Light sources

LED lamps

LED lamps
With substantial progress of LED technique in the last years today exists new product-specific designed light sources.
DAEYANG as a pioneer for innovative light systems starts with the introduction of the new Lighting this LED technique combined with optimized technique.

 

LED: Light source of the future
A good example of this is our policy for the testing and selection of LED light sources. Light Emitting Diodes are in rapid development, and the lighting industry is disadvantaged by the lack of international standards. At DAEYANG we aim to produce LED luminaires with single LEDs, LED modules and LED drivers of the best possible quality. For this purpose our test centers are hard at work identifying the components that will provide the most efficient and reliable over time when included in one of our LED luminaires.

 

5 Year Warranty

5 Year Warranty
DAEYANG warrants for 5 years on the manufacture of all LED products and material defects. This applies to defects if the product is used and installed professionally in accordance with the product data sheet, user manual. Products subject to normal wear and extreme environmental conditions are not covered by the warranty.
* Note: Please contact us for the latest version of the instruction manual and warranty terms.

 

Fluorescent lamps

Fluorescent lamps
The powerful, explosion-protected hand and machine lamps with bi-pin fluorescent lamps fulfill the requirements of ATEX directive 94/9/EC. They are generally suited for use in potentially

 

Incandescent lamps

Incandescent lamps
These lamps offer much light output because of their high efficiency despite of their small dimensions. They are not very sensitive to vibration and have proved as outdoor floodlights on board of ships. You need a ballast and an igniter. The average lifetime is about 6000 hours.

 

Sodium lamps

Sodium lamps
High intensity sodium lamps do not require secondary electrodes. The Xenon gas is ionized with the help of an external starting ignitor that also starts the discharge of sodium vapor. Beyond this starting the operation is as with metal halide lamps.

 

Halogen lamps

Halogen lamps
Traditional incandescent lamps lose part of their light intensity in the course of time since tungsten evaporates from the filament and condenses on the inside surface of the bulb forming a dark layer. In modern halogen lamps they prevent this effect by adding halogens to the filling gas. Within the so-called halogen cycle the halogens combine with the evaporated tungsten. This gaseous combination drifting with the heat flow towards the hot filament the tungsten will leave the combination and re-join the filament. The released halogens are again available for the cycle.

 

Further advantages of halogen lamps:

  • Equally bright light throughout life time
  • Nice, brilliant light for fresh colors and attractive glamour effects
  • Increased light output about 25 % compared with traditional incandescent lamps
  • Small dimensions
           

Xenon

Xenon
Xenon lamps are DC-operated lamps that are especially suited for applications requiring excellent arc stability and a high luminance. Xenon lamps are short arc lamps in which the discharge arc fires in a pure xenon atmosphere under high pressure. Xenon lamps have a very good color rendering and extremely high luminance. For this reason they are often used in light guide systems, e.g. for endoscopy or dental technology. The Xenon lamps are designed for horizontal burning position, and excel with their compact dimensions. The Xenon lamps are designed for horizontal burning position, and excel with their compact dimensions.

 

Metal halide lamps

Metal halide lamps

  • Positive Environmental Impact
    Since metal halide lamps deliver light more efficiently than incandescent, widespread acceptance of the technology has a positive effect on air quality and the environmental waste stream. Lower electrical power generating requirements means less air pollution. Efficient long-life systems mean less landfill waste.
  • Wider Range of Applications
    Specifiers can now select from a broad variety of lamp types and wattages to suit almost any application. Metal halide lighting is used today indoors and out, for industrial, commercial, retail and municipal spaces. Popular for sports facilities, and site lighting, it is increasingly found in supermarkets, big box retail, offices and lobbies.

Fire Classification

In order to restrict the spread of fire the bulkheads and decks of a vessel are constructed to a particular standard. Various standards apply depending on the type of vessel and the nature of the space surrounded. Generally the fire resistance of a bulkhead is expressed as A, B or C followed by a number indicating the time that division will prevent a specified temperature rise.

Class "B"
A division capable of preventing the passage of flame the first half an hour of the standard test. The insulation should be such that on the side opposite to a fire the average temperature will not rise more 139 °C above the original temperature nor more than 225 °C at any one point.

Class "B-15" must prevent the stated temperature rises for at least 15 minutes.

Class "B-0" must prevent the stated temperature rises for at least 0 minutes.
A Class "B" division must be constructed of approved non combustible materials except that combustible materials may be permitted provided they meet certain other requirements.

 

The lighting as a separate unit cannot be fire approved. It is the complete installation with the covering of the installed unit that have to withstand the fire load.
When completing the installation you have to have in mind:

  • Fire rating for ceiling installation
  • The maximum allowed size of recess in the actual ceiling
  • Maximum weight of fixtures/units
  • Minimum allowed distance between recesses
  • Recess construction
  • Method of fixing
  • Type of panels the lighting fixture will be accepted onto: Width and length of panel, Thickness of panel, thickness of steel plate, etc.

 

The installation on a vessel or a rig will never be exactly as the laboratory test installation. In practice there will be a mixing of cut out for lighting and ventilation as well as ceiling hatches. It is therefore very important to have in mind the minimum allowed distance between recess for the actual ceiling, as well as the maximum allowed load for each ceiling element.

IECEx and ATEX

Technically identical standards for electrical equipment since 2006. For single standards, a single set of tests and assessments can support both IECEx and ATEX. An ATEX EC-Type Examination Certificate can be based on an IECEx ExTR but ATEX documentation dose not necessarily support an IECEx certificate.The technical requirements of a manufacturer's QA system are effectively the same, both are based on ISO/IEC 80079-34 and an IECEx QAR can support the issue of an ATEX QAN.

Equipment Protection Level

IECEx for the World - Product certification:

  • Aim : One single certificate for any hazardous area product recognized and accepted throughout the world.
  • Already accepted in many countries. Alternatively a single test report(ExTR) can be sent to any member certification body(ExCB) to issue locally accepted certification.
  • Currently only electrical equipment to IEC Standards (but IEC Standards for non-electrical equipment are being developed).
  • ExCB issues an ExTR(covering the product type) and a quality assessment report(QAR) (covering the related production facility)
  • Certificates of conformity created directly on the IECEx website, fully visible for the whole world to read and check states.
  • ExCB maintains the status of certificate based on the outcome of future QARs, a minimum of 2 audit visits in a 3years period.

 

Equipment Protection Level

ATEX for Europe - Conformity Assessment:

  • A common approach to lifting barriers to trade within the European Economic Area(EEA).
  • The Directive becomes law on implementation in each member country and compliance is mandatory within the EEA.
  • Applicable to non-electrical equipment and protective system as well as electrical equipment.
  • Certification from a Notified Body is Mandatory for Category 1 and M1 equipment, protective systems and Category 2 and M2 electrical equipment. Otherwise self declaration of compliance is permitted.
  • An EC-Type Examination Certificate and Quality Assessment Notification (QAN) are issued by a Notified Body.
  • The manufacturer -alone- is responsible for the Declaration of Conformity which must accompany every product which bears the European(CE) Marking.

 

Installation and maintenance in hazardous areas

Installation and maintenance in accordance with IEC/EN 60079-10, IEC/EN 60079-14, IEC/EN 60079-17.

General requirements ( IEC/EN 60079-14 )
Hazardous areas are classified into Zones 0, 1 and 2 for gases and vapours according to IEC 60079-10-1, and into Zones 20, 21 and 22 for dusts according to IEC 60079-10-2 in order to facilitate the selection of appropriate electrical equipment and the design of suitable electrical installations.

Electrical equipment should, as far as is reasonably practicable, be located in non-hazardous areas. Where it is not possible to do this, it should be located in an area where an explosive atmosphere is least likely to occur. Electrical installations in hazardous areas shall also comply with the appropriate requirements for electrical installations in non-hazardous areas. However the requirements for nonhazardous areas are insufficient for installations in hazardous areas. Where additional protection is required to meet other environmental conditions, for example, protection against ingress of water and resistance to corrosion the method used shall not adversely affect the integrity of the equipment. Electrical equipment and materials shall be installed and used within their electrical ratings for power, voltage, current, frequency, duty and such other characteristics where non-conformity might jeopardize the safety of the installation.In particular, care shall be taken to ensure that the voltage and frequency are appropriate to the supply system with which the equipment is used and that the temperature classification has been established for the correct voltage, frequency and other parameters.

Products for use in hazardous areas are commonly designed for IEC standard voltages according IEC 60038. If a supply voltage is outside of these standardized voltages, then equipment should be specially selected and certified. All electrical equipment and wiring in hazardous areas shall be selected and installed in accordance with Clauses 5 to 13 inclusive and the additional requirements for the particular type of protection (Clauses 14 to 23). Installations should be designed and equipment and materials installed with a view to providing ease of access for inspection and maintenance (IEC 60079-17).

Equipment and systems used in exceptional circumstances, for example research, development, pilot plant where explosion protected equipment is not available, need not meet the requirements of this standard, provided that the installation is under the supervision of a competent body and one or more of the following conditions, as appropriate, are met:

  • measures are taken to ensure that an explosiveatmosphere does not occur, or
  • measures are taken to ensure that this equipment is disconnected before an explosive atmosphere occurs, in which case ignition after disconnection, e.g. due to heated parts, shall be prevented also; or
  • measures are taken to ensure that persons and the environment are not endangered by fires or explosions.
In addition, the measures or conditions or control shall be documented by a competent body who:
  • is familiar with the requirements for this, and any other relevant standards and code of practice concerning the use of electrical equipment and systems for use in hazardous areas, and,
  • has access to all information necessary to carry out the assessment.

NVG / NVIS Compatible Lights

icon_NVG_Nightvisiongoggle

Fire NVG (Night Vision Goggle) Compatible Light

NVG is intended to amplify the minimum amount of light so that objects can be seen at night. However, when the bright light of the luminaries passes through the NVG, it becomes invisible due to the amplification of the light.The NVG filter installed in the NVG compatible light enables the use of NVG by removing the light of the recognized wavelength band of NVG.
The first is to enable the night tactical activities of the NVG users, and the second is to enable the least work of the non-NVG users.
NVG compatible light is required to enable night tactical activities of NVG users and minimal work of non-NVG users.

LED lamps

Classification

Night vision imaging system(NVIS) compatible aircraft interior lighting is divided into the following types and classes.

TYPE I  Lighting compatible with any direct view image NVIS utilizing Generation III image intensifier tubes
TYPE II  Lighting compatible with any projected image NVIS utilizing Generation III image intensifier tubes.
Class A  Lighting compatible with NVIS utilizing 623nm minus blue objective lens filters with the specifications.
Class B  Lighting compatible with NVIS utilizing 665nm minus blue objective lens filters with the specifications.
Class C  Lighting compatible with NVIS having a ‘green leak’.
            This edition of this document assumes that lighting meeting class B compatibility criteria is also compatible with Class C NVIS.

Definition

2-1.Night vision imaging system (NVIS)
Any system that uses image intensifier tubes to produce an enhanced image of a scene in light conditions too low for normal navigation and pilotage.

2-2.Direct view image NVIS (Type I)
Any NVIS that uses generation III image intensifier tubes and displays the intensified image on a phosphor screen in the user’s direct line of sight.

2-3.Projected image NVIS (Type II)
Any NVIS that uses generation III, image intensifier tubes and projects the intensified image on a see through medium in the user’s line of sight. This configuration allows simultaneous viewing of the intensified image and visual cues such as HUD symbology.

2-4.Class A NVIS
Class A NVIS is not compatible with red cockpit lights because of the overlap between the spectrum of red light and the sensitivity of Class A NVIS

2-5.Class B NVIS
A Class B NVIS is compatible with NVIS Red and therefore is compatible with properly filtered red lights and color electronic displays that meet the requirements of Table II,III .

2-6.Class C NVIS
Some aircraft have HUDs that use a hologram as the reflective element in the combining glass. Holograms typically work with only one wavelength of light. This feature can be used to improve the efficiency and see-through clarity of the HUD, but it means the light coming from the HUD is concentrated at one wavelength. since this wavelength is in the green part of the spectrum and is blocked by the minus blue filter in the NVIS, it is nearly impossible to see a holograph HUD with Class A or Class B NVIS. Consequently modified NVIS have been built and tested which have a ‘notch’ or ‘leak’ in the green part of the spectrum The Class C filter is sometimes called the ‘leaky green’filter.

2-7.Compatible interior lighting
The aircraft interior lighting that provides acquisition of aircraft interior information with the unaided eye without degrading the image intensification capabilities of the NVIS during night flight operations. Conforming to the detailed performance and test requirements specified herein shall be considered as meeting this definition

2-8.Secure
An army definition often applied to ground vehicles and equipment meaning that the visible light emitted is reduced to the minimum needed to do the mission and the near IR content is reduced to less than an estimated 5% of the visible light.

2-9.Friendly
Exterior lighting that is fully usable by people without NVIS but has drastically reduced IR content so that it can be used while flying formation with aircraft in which NVIS are being used.

2-10.Covert
IR lights or lights that are typically filtered so they are not visible to the naked eye beyond approximately 20 to 30 feet. These lights may be intended to provide illumination so that NVIS will work without adequate natural light.

Relative spectral response characteristics of Class A,B,C NVIS

This document defines the radiant energy interface requirements and test procedures applicable to NVIS compatible lighting systems for new or modified aircraft lighting equipment and crew stations. Figure is the assumed NVIS spectral response characteristics that shall be used to define NVIS compatibility criteria herein.NVIS_spectral_response
Relative spectral response characteristics of Classes A, B and C NVIS

NVIS lighting color limits

The color of illuminated information on instruments, control, control panels, and on illuminated areas in designated crew station and compartment areas shall be as specified herein for that component. These lighting colors and limits are shown on the chromaticity diagram and are designated as ‘NIVS GREEN A’, ’NVIS GREEN B’, ’NVIS YELLOW’, ‘NVIS RED’, ’NVIS WHITE’

Conformance to these colors and color limits is determinated by the following formula(u’- u1)2 + (v’- v1)2 ≤( r ) 2
where ;u’and v’ = 1976 UCS chromaticity coordinates of the test article
       u1’ and v1’= 1976 UCS chromaticity coordinates of the center point of the specified color area
       r = radius of the allowable circular area on the 1976 UCS chromaticity diagram for the specified color
NVIS_color_limit
CIE 1976 UCS Chromaticity Diagram

NVG compatible and incompatible lighting relative to the NVG response

A complication is the existence of different ‘classes’ of NVG, which refers to the exact response bands of the devices. Class A NVGs have a response that starts at around 625nm and extends to about 930nm, while Class B NVGs respond in the range 655nm to 930nm.
These wavelengths are controlled by the use of special filters, often referred to as ‘ minus blue’ filters, mounted on the front of the NVGs.
NVIS_NVG_response

NVG compatible green & red lighting and Class A & B NVG response

One effect of this is that it is harder to make lighting compatible with Class A NVGs than Class B.
Indeed red lighting can not be used successfully in a cockpit with Class A NVGs.
MIL-STD-3009 takes account of these two classes in defining colors and levels of compatibility.
They relative responses of Class A and Class B NVGs, with NVG compatible green and red light outputs superimposed.
NVIS_NVG_response

NVG compatible & NVG friendly light relative to NVG response

Whereas internal lighting is generally required to be very compatible, with negligible impact on NVGs, external lighting needs Lighting needs to be visible, both through NVGs and to the naked eye, in order to perform its intended function of providing awareness of position and direction of flight.
This means there has to be a greater degree of overlap between the emissions and the NVG response, but not so much that the NVGs are degraded -a balance is required where an NVG friendly light output is compared with an NVG compatible source, relative to the Class B NVGs response

IP and IK Classification

Indicates IP rating

IP CLASS

IP (Ingress Protection) classification tells us the product capability to avoid ingress from water or solid objects. The first number refers to solid objects/dust and the second to water. DAEYANG has laboratories for testing IP classification. Mainly, higher IP-rating means higher dust and watertightness.

IP and IK Classification
 If one or both numerals are stated as "X", the product could not be subjected to the relevant test. The statement "X" cannot, however, be used to signify any random IP rating.
 

IP protection degrees for enclosures

Degrees of protection against solid foreign objected by the first characteristic numeral.

First characteristic numeral : Protection against solid bodies
