Problems solved by technology

[0003] At present, electrical methods and spectroscopic methods have been used to measure the junction temperature of LED lamps, but the detection device can only detect the junction temperature of the entire LED lamp or LED module, and cannot accurately obtain the junction temperature of each LED in the LED lamp. The damage of any LED will cause the failure of its LED module or the entire LED lamp, making the LED lamp unable to work normally

Abstract

The invention discloses a junction temperature measuring device for an LED (Light Emitting Diode) lamp, which comprises a plurality of optical fibers, optical fiber fixing seats, a moving mechanism, a lifting mechanism, a universal clamping platform, a counterweight mechanism and a frame, wherein each optical fiber is fixedly arranged on the moving mechanism by one optical fiber fixing seat, and the moving mechanism is arranged on the lifting mechanism; the LED lamp is arranged on the universal clamping platform, and the counterweight mechanism is fixedly arranged at the bottom of the universal clamping platform; and the lifting mechanism and the universal clamping platform are arranged on the frame, and a diaphragm structure is arranged on each optical fiber fixing seat. The LED lamp can stably rotate along with the universal clamping platform through a counter weight, the positions of the optical fibers are adjusted by the moving mechanism and the lifting mechanism, and each diaphragm structure eliminates the impact of other LEDs or stray light in the LED lamp on the measured LED spectrum acquisition, so that the spectrum of each LED in the LED lamp is acquired, and thus the junction temperature of each LED is accurately obtained, and the operation is convenient and quick.

Description

technical field [0001] The invention relates to a junction temperature measuring device of an LED lamp. Background technique [0002] With the rapid development of semiconductor lighting technology, lamps with high-power LEDs as light sources (such as LED street lights, LED car lights, etc.) are being gradually developed, and related applications are being carried out. Since the application of these high-power LED lamps is in its infancy, there are great differences in the technical status and functional performance of the products. On the one hand, users urgently need to obtain LED lamps with stable performance, safety and reliability, energy saving and environmental protection, and long life, but there is no quantitative selection standard for product performance (especially reliability, life, etc.) of different manufacturers; Manufacturers lack technical means to quantify the quality, reliability, and lifespan of LED lamps in a short period of time, which severely restri...
