Why Photobiological Testing of LED Lighting Is Important

A large number of light sources including LEDs and Incandescent lamps discharge Ultra Violet (UV), Infra-red and blue and white light, which are probably hazardous to the human being eyes and skin. The three parts of the body that can be damaged by hazardous lights would be the epidermis, the front of the eye (cornea, conjunctiva and the lens) and the retina in the back of the attention. The hazard affecting the retina is UV light triggering denaturation of protein and key biological components, leading to deterioration in view creating possible loss of sight and the need for glasses.

The image organic effects caused by lighting fixtures and luminaires mean suppliers carry great burden of responsibility, and should be doing all they can to ensure the basic safety of their products. A large number of LED chip suppliers are already testing for image biological effects. However, once we manufacture LED lamps and luminaires, the new system we have created has altered these test results. This raises serious questions whenever we purchase LED. Offers the supplier tested to ensure safety? If there is a claim in the foreseeable future, where does the the liability sit? Will the distributor still be in operation should a claim arise? And would this mean the end user becomes responsible? This tells us the supplier and the end user need to make sure they see evidence of testing for these effects. The test data should form part with their due persistence or tender process.

Generally there is a standard which exists today for the image biological safety of lamps and lamp systems, EN 62471: 2008. Particularly, the typical specifies the publicity limits, reference measurement approach and classification scheme for the analysis and control of image biological problems from all electrically power incoherent broadband sources of optical radiation, including LEDs.

The testing standard provides us with a description scale categorised into Risk Groups (RG) depending how hazardous the light source is. The higher the group, the greater hazardous the image biological effects will be. You will discover four RGs ranging from RG0 – RG3

So what about the growing popularity of LED lighting? LED lighting are one of this most energy efficient and quickly developing lighting systems and found in many non commercial and commercial environments. The LED or light-emitting diode lasts longer than typical lighting and is more powerful. LED lighting when in contrast to other varieties of light not only lasts for a longer time that other varieties of typical lighting but offers better lighting quality which is much more efficient.

The future with this country really is brighter as LED lamps technology can significantly change the future of lamps in the UK. Very good quality LED products use much less energy and last longer than normal incandescent lamps

LEDs are the size of a fleck of pepper, and a mix of red, green, and blue LEDs is typically used to make white light. LEDs emit light in a specific direction, reducing the advantages of reflectors and diffusers that can snare light. This feature makes LEDs better for many uses such as indented down lights and activity lighting. With other types of lighting, the light must be reflected to the required direction and more than half the light may never leave the fixture. LEDs emit very little heat. In evaluation, incandescent bulbs release 90% with their energy as heat

LEDs are being used in a large variety of ways both commercial LED lighting and standard residential usage. The beauty of this is that as the CONTRIBUTED technology develops and increases more and more people will be using them which will bring about lower prices for the products.
