Abstract

The invention discloses a device for detecting aging of fluorescent powder. The device comprises a blue light lamp, a metal tube, a metal cover and a photoelectric detector. The blue light lamp comprises a lamp panel and a plurality of blue light chips. The plurality of blue light chips are arranged and packaged on the first surface of the lamp panel in an array manner; the lower end of the metaltube is embedded into a circular groove; a glass sheet is mounted in the metal tube; the glass sheet divides the inner cavity of the metal tube into a first inner cavity and a second inner cavity which are arranged up and down in an axial direction; the photoelectric detector comprises a detector body, a detection circuit and a detection probe. When aging detection of the fluorescent powder is carried out, the fluorescent powder is flatly laid on the glass sheet. The detection device provided by the invention can simulate the working condition and the aging degree of the fluorescent powder under an extreme condition; meanwhile, a switch of the blue light lamp can be controlled to simulate the working condition and the aging degree of the fluorescent powder in actual work.

Description

technical field [0001] The invention belongs to the technical field of photoelectric performance detection, and in particular relates to a detection device for fluorescent powder aging. Background technique [0002] With the continuous rapid development of photoelectric technology and the continuous improvement of lighting technology, LED fluorescent lighting has gradually replaced energy-saving lamp lighting recently, becoming one of the earliest LED lamps to enter the room. But the photoelectric conversion efficiency of LED lamps is about 20%, and most of the rest is converted into heat. [0003] The main problems that affect the life and efficiency of LEDs come from the heat quenching and light decay caused by the heat generated by LEDs concentrated in fluorescent materials. Therefore, the essence of solving this problem is to improve the thermal conductivity and heat distribution uniformity of the fluorescent material. The study found that in LED packaging, it is neces...
