Understand the LED street light heat dissipation problem dynamic | | industry of lamps and lanterns lighting: the rural solar LED street lamp manufacturers

LED street light use of LED light source, cold light, although it is not what the hot body, but the LED street light in the process of lighting, when the current through the LED heat resistance or can make the lamp body temperature, semiconductor materials produced by the LED will rapidly aging at high temperature. So, in order to droop down to slow the LED lighting, LED street lamps and lanterns have longer service life, we must reduce the junction temperature of LED chip, to reduce the junction temperature, will reduce the lamp body temperature, and to reduce the thermal resistance between LED chips and light body. This is we solve the problem of LED street lamps and lanterns, heat dissipation. LED lights for outdoor lamps, it USES the LED lamps and lanterns is generally above IP65 protection grade, this request if shell material of metal material, so that LED to connect to the aluminum substrate, aluminum substrate heat effectively conduction to the surface of the shell, won't make the gathered heat can make the aluminum substrate temperature has risen sharply, the LED high temperature caused by increasing the possibility of failure, cause the LED road light failure, shorten service life. Actually, want to care about is whether the temperature of the LED street lamp parts within the temperature range of can tolerate, that is to calculate these parts at the temperature of the thermal stability, because the lamps and lanterns is in open after heats up, finally to achieve thermal stability state, that is to say, each point has the highest temperature of thermal stable state, so the heat calculation of lamps and lanterns of steady state is considered, the transient temperature distribution is not important.
