Therefore, selecting and designing a heat dissipation technology method suitable for heat dissipation of LED lamps will have very important practical significance for the application of LED lighting products.

Standing lamp and a 16-watt LCP-16WLED water-cooled pendant lamp. However, there is currently no relevant technology that considers the heat dissipation of the system from the perspective of the entire LED lighting system, especially an integrated heat dissipation solution for a large lighting system composed of multiple high-power LED lighting systems.

对LED灯具水冷装置进行性能测试,结果如下: The performance test of the water-cooling device for LED lamps is carried out, and the results are as follows:
参照图6,相同条件下,对于不同功率的LED光源模组,对比水冷单元内部有散热片与没有散热片的情况,有散热片的冷却效果明显优越于没有散热片的散热效果。随着LED光源模组的功率增大,使用散热片的LED光源模组的最高温度的增长速率远小于没有使用散热片的;当功率从36W增大到108W,使用了散热片的水冷单元,LED光源模组的最高温度只增加了15度,控制效果明显。 Referring to Figure 6, under the same conditions, for LED light source modules with different powers, comparing the cases with and without heat sinks inside the water cooling unit, the cooling effect with heat sinks is obviously superior to that without heat sinks. As the power of the LED light source module increases, the growth rate of the maximum temperature of the LED light source module using a heat sink is much smaller than that without a heat sink; when the power increases from 36W to 108W, the water cooling unit with a heat sink, The maximum temperature of the LED light source module is only increased by 15 degrees, and the control effect is obvious.
参照图7,相同条件下,对于不同功率的LED光源模组,对比使用水冷却和使用空气自然冷却的冷却方式,使用水冷的效果明显优越于使用空气自然冷却的效果。随着LED光源模组的功率增大,使用水冷却的LED光源模组的最高温度的增长速率远小于使用空气自然冷却的;当功率从36W增大到108W后,使用水冷却的LED光源模组的最高温度只增加了约14度,控制效果明显。 Referring to Figure 7, under the same conditions, for LED light source modules with different powers, comparing the cooling methods of using water cooling and using air natural cooling, the effect of using water cooling is obviously superior to that of using air natural cooling. As the power of the LED light source module increases, the growth rate of the maximum temperature of the LED light source module using water cooling is much smaller than that of the natural cooling of the air; when the power increases from 36W to 108W, the LED light source module using water cooling The maximum temperature of the group only increased by about 14 degrees, and the control effect was obvious.
参照图8,分析不同高度的水冷单元的高度对散热效果表明改变水冷单元尺寸对散热效果影响并不大;对不同功率的LED光源模组,高度分别为95cm和65cm的水冷单元相差的LED光源模组的最高温度只有2-4度,暗示着水冷单元小型化存在较大的优化空间。 Referring to Figure 8, the analysis of the height of water-cooling units of different heights on the heat dissipation effect shows that changing the size of the water-cooling unit has little effect on the heat dissipation effect; for LED light source modules with different powers, the LED light sources with different heights of water-cooling units of 95cm and 65cm are different The maximum temperature of the module is only 2-4 degrees, implying that there is a large room for optimization in the miniaturization of the water cooling unit. the
参照图9,使用本实用新型装置及方法,并测量80W的LED光源模组的基板温度表明,在外界条件一定时,LED光源模组的基板温度达到一个可控平衡温度,控制效果明显。在室温13度的时候,基板的平衡温度只上升到约46度,散热效果优越。 Referring to Fig. 9, using the device and method of the present invention, and measuring the substrate temperature of the 80W LED light source module shows that under certain external conditions, the substrate temperature of the LED light source module reaches a controllable equilibrium temperature, and the control effect is obvious. When the room temperature is 13 degrees, the equilibrium temperature of the substrate only rises to about 46 degrees, and the heat dissipation effect is excellent.
