Abstract

The invention provides an experimental device for the LED chip heat radiation testing. The device comprises an adjustable support, a power supply module, heat insulation material, an LED chip to be tested, a heat radiator and a temperature measuring instrument. The adjustable support comprises a fixing base, a supporting rod and a height adjusting rod; the heat insulation material is installed on the fixing base of the adjustable support; the LED chip to be tested is installed above the heat insulation material; the heat radiator is installed above the LED chip to be tested. The power supply supplies the operating voltage for the LED chip, fan and other active heat radiation devices, and the temperature measuring instrument measures the temperature of the LED chip to be tested. The experimental device is simple in structure and convenient to install and operate, and the active and natural heat radiation experimental testing can be performed on the LED chip.

Description

Technical field [0001] The technical field of LED heat dissipation of the present invention specifically relates to an experimental device for testing the heat dissipation of LED chips. Background technique [0002] In the modern rapid development of LED lighting, LED lamps are favored by people due to their energy-saving, long life and easy maintenance characteristics. More and more LED lighting will be used in various parts of production and life, but the current technology has certain limitations, mainly in the life of LED lamps and maintenance of light efficiency will present huge challenges. The lifespan of LED lighting depends on heat dissipation, power supply technology and lamp bead technology. At present, lamp bead technology and power supply technology have been widely resolved. The lifespan of lamp beads can reach 2-3 million hours, and the power supply can also reach 1.5-5 Ten thousand hours of life, the life of lamp beads directly depends on the heat dissipation tec...
