Solution to the heat dissipation problem of high-power LED tube

    Whether the high-power LED tube can work normally, the quality of the lamp beads is directly related to the heat dissipation of the high-power LED tube. Now the heat dissipation of the high-power LED tube is natural heat dissipation. The effect is not ideal. High-power LED The lamp bead is composed of LED; heat dissipation structure; driver; lens. The heat dissipation part is a very important part. The quality of heat dissipation directly affects the service life and conditions of high-power LED tubes.

Regarding metal heat dissipation substrates, currently there are aluminum substrates and copper substrates. As a professional manufacturer of metal substrates, it is recommended that you use cost-effective aluminum substrates. The price of copper substrate and aluminum substrate are quite different. Copper substrate is better than aluminum in terms of thermal conductivity, but the cost and weight are much higher than aluminum. Aluminum substrate is recommended. Furthermore, some manufacturers of high-power LED lamp beads add a temperature control switch to the high-power LED lamps and set the temperature value, and when the temperature here is higher than this value, the current is reduced. The disadvantage is that the light will be darker, but the effect is not big, so this method is still feasible

Temperature protection is a must. The product is not only required but also responsible for the customer. How much temperature protection is appropriate? Calculate it. The maximum ambient temperature is 40°C in summer, 50°C in summer light exposure, and 50°C ambient temperature is practical. Refer to the general high-power LED lamp bead specifications. The junction temperature is acceptable at 120°C. The thermal resistance from the chip to the aluminum substrate, The specification generally recommends 10-15℃, and the LED substrate should be guaranteed to be at 120-15=105℃. Good, the retained temperature difference is taken as the intermediate value of 50-105°C, 77.5°C. Generally, the operating temperature of electronic components is reliable at 85°C, and 77°C is in line with this principle. It is recommended to start the protection at 77°C, reduce the current drastically before 85°C, and complete the product temperature protection function at 90°C.
