How to buy LED fluorescent tubes
Light source material
Led belongs to point light source. If a poor LED is used, the LED will release a lot of heat during operation, resulting in a rapid rise in the junction temperature of the tube core. The higher the LED power, the greater the heating effect. The increase of LED chip temperature will lead to the change of light-emitting device performance and the attenuation of electro-optic conversion power, and even failure in serious cases.
Driving current
The greater the current flowing through the LED within its current limit parameter scale, the higher its luminous brightness. That is, the brightness of the LED is directly proportional to its operating current. However, if the current flowing through the LED exceeds the limit parameter scale, the LED will be saturated, which will not only greatly reduce the luminous power, but also shorten the service life. The quality of LED power supply directly restricts the reliability of LED products.
Heat dissipation
The heat accumulation of LED tube not only affects the electrical performance of LED, but also may eventually lead to LED failure. Therefore, in order to ensure the longevity of LED lamps, heat dissipation has become a key technology in the application of white LED.
