3W LED Power thermal problems beads:
Now many companies develop and produce LED urban lighting lamps.As is the array for low-power LED light, heat issue is resolved, the increase in the number with the LED.
Strong low-power LED light failure, the installation costs are high;Cities with high-power LED lighting LED lights are the trend.High power LED lamp beads are now more and more mature technology, LED heat problem was an effective solution.
LED control of astigmatism and the condenser;Lamps light the road surface illumination range, type and illumination of the balance;Photoelectric conversion efficiency have been effectively resolved, LED lumens has increased.
The main problem is the LED heat lamps and a good supporting drivers.These are decisions of the lamp life.Therefore, we conducted a study on the development of this high-power LED lamp beads, can be used in indoor lighting and street lighting.Quality assurance is also useful.
Using high-power lamp beads should be noted:
1.High-power lamp beads coated thermal plastic need to make a good heat dissipation.( Thermal plastic is very important)
2.Would also like to add a large aluminum plate, increase the heat dissipation area.
3.Aluminum cooling temperature is lower than 60 °C
