What does LED street light rely on to achieve the heat dissipation effect?
The heat dissipation effect is good because it incorporates a seemingly ordinary white semiconductor chip, the size and thickness are equivalent to dried tofu. The only difference is that one side of the chip is connected to two wires, one red and one black. If the two wires are connected to positive and negative DC power supplies, the chip, which was originally at room temperature, will quickly cool down on one side, and the surface will condense into water droplets. The other side will become hot, even hot.
This chip is the core of the heat dissipation of LED street lamps. It is used to cool the road LED street lamps. It can ensure that the lamp bead's working temperature is below 60 ℃, completely solve the LED light decay problem and improve the life of the street lamp. After switching on the positive and negative currents, the single-sided temperature can quickly drop below 0°C within 90 seconds.
Naturally, it is impossible to rely on only one chip. When making, first install the LED lamp on a high-conduction uniform temperature aluminum substrate through a grid matrix circuit, and then determine the number of chips and heat sinks according to the power of the LED lamp , To ensure that the temperature of the light board is always controlled within 60 ℃, completely solve the problem of high-power LED street light attenuation, and improve the service life. At the same time, the total weight of street lights can be reduced by more than 70%.
