First, heat dissipation
The heat accumulation of the LED tube not only affects the electrical performance of the LED, but may also eventually lead to LED failure. Therefore, in order to ensure the life of the LED lamp, heat dissipation becomes a key technology for white LED application, and reducing or rapidly dissipating the heat generated by the LED becomes the primary problem in the application design of the white LED.
Second, the light source material
LED is a point light source. If poor LED is used, the LED will release a lot of heat during the working process, which will make the junction temperature rise rapidly. The higher the LED power, the greater the heating effect. The LED chip temperature will rise. It causes the change of the performance of the light-emitting device and the electro-optical conversion efficiency to attenuate, and even fails in severe cases.
Third, the drive power
The quality of LED power supply directly restricts the reliability of LED products. Therefore, the requirements of efficiency conversion, effective power, constant current accuracy, power supply life and electromagnetic compatibility of LED driver power supply are very high for foreign customers in the international market, because the power supply is throughout The role of a luminaire is just as important as a human heart.
Fourth, the drive current
The greater the current flowing through the LED in the range of its current limit parameter, the higher the brightness of the LED. The brightness of the LED is proportional to its operating current. However, if the current flowing through the LED exceeds the limit parameter range, the LED will Saturation occurs, which not only greatly reduces the luminous efficiency, but also shortens the service life.
Fifth, light distribution processing
LED is a directional point source. How to creatively apply this feature of LED to create a comfortable light environment is the core of LED light optical design technology. The LED light source itself generally has a lens or a transmissive material for improving the light emission efficiency, and at the same time satisfies the light distribution of about 120 degrees of light emission, which is generally called a primary optical design. However, in order to meet the various needs of indoor lighting, it is necessary to redistribute the light according to the needs, and the way to distribute the light emitted by the LED to achieve a comfortable light environment is also an important factor affecting the quality of the LED.
