Learn From the Parameter Value to Understand the LED Light Source Module

LED light source module parameters: 1. Light flux gear: The optical flux value is an indicator that LED users are very concerned. LED application customers must know which range of LED optical flux they use to ensure the uniformity and consistency of their product brightness and consistency sex. 2. Reverse leakage current test: The reverse leakage current should be lower than the required value under a certain voltage. During the production process, the LED reverse leakage current is too high due to factors such as static electricity and chip quality. The module lays a great hidden danger, and it is easy to cause LED dead lamps after a period of time. 3. Positive voltage test: The range of forward voltage needs to be within the scope of the circuit design. Many customer design drives the light emitting pipe to light up with a voltage. The forward voltage can directly affect the overall parameters of the circuit. It will bring hidden dangers to the quality of the product. In addition, products that require the power consumption of some circuits, you hope to ensure that the same light -emitting efficiency, the lower the voltage, the better. 4. Relative color temperature division: For white light LED color temperature is a parameter that represents the color industry, this parameter can directly present whether the LED color tone is warm or cold or white is white or white. 5. Color seat label x, y dividing: For white light or monochrome light, you can use color parameters to express which color area LED is in, generally requires four o'clock x, y to determine a color area area. It is necessary to ensure whether the LED is required to fall in the required four points X, Y color area. 6. Main wave length: For monochrome light LED, the main wavelength is an important indicator of the color parameters of its color parameters. The main wavelength directly reflects the visual experience of the light of the LED. 7, color rendering index split: color rendering index is directly turned off S to the degree of discoloration of objects on the object, which is very important for the parameter of LED lighting products.
