2835 LED tube heat dissipation problem
2835 LED lamp beads are used more and more because of its many advantages, especially the LED light source (2835) with a patented structure of Taiwan wafer. The chip is placed on the pin, and the heat energy directly transfers the chip node to the pin. The heat generated is different from traditional in-line products and traditional SMD products in terms of heat dissipation. The node temperature of the chip will not accumulate, thus ensuring the good usability of the light source lamp beads and ensuring the light source lamp beads Long life, low light decay.
In traditional SMD products, although the positive and negative electrodes can be connected through the gold wire of the chip, it also allows the heat generated by the chip to be connected to the silver pin through the gold wire. The conduction of heat and electricity is conducted by money, and the heat accumulation time is long. Will directly affect the life of the LED fluorescent tube. The introduction and application of infrared radiation heat dissipation to the LED tube is an important means to improve the service life of the LED tube. In consideration of heat dissipation, we separate the heat dissipation of the LED light source lamp beads and the heat dissipation of the power supply, and do not interfere with each other, so as to ensure the rationality of heat dissipation.
Safety, here is mainly the PC flame-retardant plastic tube, because the infrared heat can penetrate the PC tube, when we design the use of LED lights, we can consider its safety more, and use the all-plastic physical insulation method, even if it is not used. The isolated power supply can absolutely guarantee the safety of use. There are three ways of heat conduction, convection, conduction and radiation. In a closed environment, convection and conduction may be less likely to be achieved, and heat dissipation through radiation is the focus of LED tube consideration.
The development of LED fluorescent lamps has been around for a long time. From the perspective of energy-saving effects, its future applications are quite broad. In addition to energy-saving, its safe and long-life use is something we should pay more attention to!
When choosing an aluminum substrate, use aluminum with high thermal conductivity, which is conducive to heat dissipation, and the aluminum tube should be close to the aluminum substrate.
