High-power LED street lamp features:
1. high transmittance (> 97%) of flexible packaging materials, substrates and packaging materials to eliminate the stress due to thermal expansion and contraction.
2. heat pipes and aluminum fins with high-density cooling mode, the heat can quickly export the chips, the chip temperature is maintained at its maximum allowable operating temperature.
3. affirm the power control and power LED driver IC, power efficiency "90%, and light stability.
4. a single chip power of 5-12W, high luminous flux to the ground, suitable for road lighting.
5.PCB of series-parallel circuit design, fault the wind is low, easy to mass production.
6. to use a different color temperature, CRI high.
7. heat sink down and difficult to attach due to dust or bird droppings, the lower heat dissipation, resulting in light failure or malfunction.
