UV test also known as UV aging test which is a process of simulating the various factors involved in the actual use of the product to carry out corresponding conditions to strengthen the experiment on the aging of the product. The UV aging test experiment is mainly for plastic materials, and the common aging mainly includes light aging, damp heat aging, hot air aging. The ultraviolet aging test ch...
Vibration test is to simulate the various vibration environment impacts encountered by the product in the transportation, installation. This test is to simulate the various impacts encountered by the product in the transportation, installation and use environment. This kind of vibration environmental impact is used to determine whether the product can withstand various environmental vibrations. Vi...
Electromagnetic compatibility difficulties in electrical engineering include the impact of electromagnetic coupling, electronic switching, and semiconductor devices on power quality. Restricting or reducing electromagnetic energy creation, propagation, and reception in the electromagnetic environment affects all linked system devices in the environment. The conducted emissions are measured by usi...

The reason why LED lighting is easy to spread the flame inside the equipment insulation material or other solid combustible material parts may be ignited by the glowing wire or hot components. Under certain conditions, such as fault current flowing through wires, component overload, and poor contact, some components will reach a certain temperature and cause nearby parts to ignite. The glow wire t...
LED chip are small in size, low energy consumption, long life, and other advantages, which promote their rapid development and are widely used in various fields of lighting. Among them, long life is a very important advantage of LED lights. To ensure this advantage of LED, R & D personnel need to ensure good EMC and reliability of the LED power system. Power system compatibility The root of im...
In LED lighting products, due to the heat generated by some high-current components, their own temperature rise is often too high. Working in this state for a long time may reduce or destroy the characteristics of the insulating materials in the product, resulting in electric shock or even fire. The dangerous result of the product; the temperature of the accessible parts such as the product shell ...
The International Electrotechnical Commission (IEC) created the IEC 60068 standard, which is widely accepted throughout the world. Environmental testing for electronic equipment, components, and electromechanical products is covered by IEC 60068, which is a collection of methods for determining the performance and survival of these items under various environmental conditions such as transportatio...
Definition of light distribution curve: It refers to the light intensity distribution of light sources (or lamps) in all directions in space. On the metering plane passing through the center of the light source, the light intensity values of the lamps at different angles are measured. Starting from a certain direction, the light intensity of each angle is marked with a vector with the angle as a f...
