Photobiological Safety

As the technology and performance of LEDs have progressed, there are increasing concerns regarding optical radiation produced by LEDs, and the potential exposure risks to humans. Therefore, we apply the necessary testing against blue light hazard in our lighting fixtures.

Goniophotometer (C Type)

It is used to measure the intensity of light leaving a luminaire at various vertical and horizontal angles.

 

From this information, the photometric light distribution of the luminaire is derived, and quantities such as total lumen output, luminaire luminance, zonal lumen summary and other information that is included in a photometric report can be computed.

Light Transmittance

Light Transmittance and Haze Tester is the best suitable instrument for evaluation of light transmitting and light scattering properties of transparent materials.

The transmittance of an object or instance of material measures its effective transmission, given as a ratio of the total amount of light or electromagnetic radiation that is transmitted compared to the whole amount incident upon it.

Corrosion Test
(Salt Spray Test)

Stimulate the actual natural conditions to do accelerated corrosion test; all the testing are based on common states on the natural environmental: such as combine with salt spray, hot air drying, humidity, low temperature, etc.

Electrical Safety

Testing electrical and electronic products for electrical safety is intended to identify the potential risk of electrical shock to users. Evaluating a product for electrical safety usually includes the following tests:

High voltage test (dielectric withstand test) - measures the ability of an electrical product to withstand a high voltage applied between a product’s electrical circuit and ground. Leakage current test - evaluates whether current that flows between an AC source and ground does not exceed a specified limit. Insulation resistance test - calibrates the quality of the electrical insulation used. Ground continuity test - ensures that a clear path is available between all exposed metal surfaces and the power system ground.
