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...
A goniophotometer is a device that combines the functions of a photometer with those of a goniometric motion stage to create a single instrument. This process is also called goniophotometry. Specifically, the photometer is a photoelectric light meter that replicates the photopic spectrum sensitivity of the human eye by converting incoming illumination into an electric current. The quantity of ligh...
A drop test generally refers to a free fall drop at a certain height after the product is packaged (in the outer box), and finally see if there is any damage. The drop test is mainly used to test the damage of the product after it is packaged. It is used to evaluate the impact strength of the component when it is dropped during the handling process, and the water chestnut, corner and surface of th...
Climate chambers are enclosed spaces used to evaluate the impact of certain environmental conditions on biological things, industrial goods, materials, and electrical devices and components. Environmental chambers may also be called environmental chambers. An environmental test chamber simulates real-world circumstances to which equipment, materials, devices, or components may be subjected. ItR...
