Contrast LED bulb cooling water cooling and traditional way

by Ente G. LED lighting for sale
Traditional metal cooling LED bulbs through a metal heat sink cooling, this approach has two drawbacks, including thermal performance and high prices. This time liquid cooling LED bulb is proposed. But there is little on its thermal performance and life parameters studied. This experiment compares the liquid cooling LED bulb and traditional metal cooling LED bulb thermal performance and life. By finite element software to simulate the transient and steady-state temperature change characteristics of these two lamps, a temperature curve and obtain steady-state temperature field. Through a life cycle process, evaluated life. The results show that its liquid cooling fixture junction temperature is below 40 ℃, at 3W when life is 6.28 times the theoretical tradition of LED lamps. The junction temperature rise rate of the liquid cooling LED lamps is slow. Liquid Cooling LED lamps are more reliable, more long life.

Experimental procedure: First, the thermal performance simulation of the liquid cooling LED bulb and traditional metal heat sink LED bulb, awakened from two lamps structural analysis; and analysis of traditional metal cooling LED bulb structure, reanalysis liquid cooling LED bulb structure, then the simulation results of the two LED bulb is compared, and finally life assessment of two LED bulb. led explosion proof lighting

From the above analysis of a series of comparative experiments in the final conclusion is the temperature field simulation and two LED bulb life assessments, the liquid cooling LED bulb lowers junction temperature by 40.2 ℃, its life is 6.28 times more than a traditional LED bulb. Thermal performance liquid cooling LED bulbs are better and live longer. Since there is no metal heat sink, the liquid cooling structure of the lamp is cheaper. LED Underwater Fishing Lights
