Study on Temperature Rise Characteristic of LED Lighting Fixture under Different Conditions

The temperature rise characteristic of LED lighting fixture under different conditions was studied in the paper. The experimental results showed that the temperature rise of LED lighting fixture under the condition of with cover and no dust was about 1.5 times higher than that of LED lighting fixture under the condition of no cover and with dust. Apparently, the influence of the cover on the heat dissipation of LED lighting fixture was much larger than the dust.
