Introduce the parameter value of LED light source module

LED LED Light module source module parameters:

1. Luminous flux classification: Luminous flux value is an indicator that LED users are very concerned about. LED application customers must know which range of LED luminous flux they use, so as to ensure the uniformity and consistency of their product brightness.

2. Reverse leakage current test: The reverse leakage current should be lower than the required value under a certain voltage. The LED reverse leakage current is too high due to static electricity, chip quality and other factors during the production process, which will Bury a great hidden danger to the LED light source module, and it is easy to cause the LED to die after a period of use.

3. Forward voltage test: The range of forward voltage needs to be within the allowable range of the circuit design. Many customers design to drive the LED to LED Light module up in the form of voltage. The magnitude of the forward voltage directly affects the overall parameters of the circuit. Change, which will bring hidden dangers to product quality. In addition, for some products that require circuit power consumption, it is desirable to ensure that the forward voltage is as low as possible under the same luminous efficiency.

4. Relative color temperature classification: The color temperature of white light LED is a parameter that is used to characterize its color industry. This parameter can directly show whether the color of the LED is warm, cool or white.

5. Chromaticity coordinate x, y bin: For white light or monochromatic light, chromaticity parameters can be used to express which color area the LED is in. Generally, four points x, y are required to determine a chromaticity area. Certain test methods must be used to ensure whether the LED falls within the required four-point x, y chromaticity area.

6. Dominant wavelength binning: For monochromatic LEDs, the dominant wavelength is an important indicator to measure its color parameters, and the dominant wavelength directly reflects the human eye's visual experience of the LED light.

7. Color rendering index classification: The color rendering index is directly closed to the degree of discoloration of the object on the object when the LED Light module is irradiated. This parameter is very important for LED lighting products.
