Embodiment approach

[0025] As an embodiment of the present invention, the wrapping arrangement wraps the heater on the outer wall of the air outlet pipe 6, which can achieve a sufficient heating effect and achieve the purpose of accelerating the operation of the cooling system of the lamp; There is a gap between 6 to prevent the temperature of the heater from being too high to cause the outlet pipe 6 to rupture; the half-side setting sets the heater on the side of the outlet pipe 6 away from the return pipe 7 to prevent the temperature of the heater from affecting the cooling and returning heat transfer fluid 2.

[0026] As an embodiment of the present invention, the upper vitreous body 12 and the lower vitreous body 13 are seamlessly fixedly connected by a sealant 14; the air outlet pipe 6 and the upper vitreous body 12 are seamlessly fixedly connected by a sealant 14; The backflow pipe 7 and the upper vitreous body 12 are seamlessly connected by a sealant 14; the fixed ring 8 is an interference...

Abstract

The invention belongs to the field of photoelectronic device service life prolonging and particularly relates to a method for prolonging the service life of an LED lamp. According to the method, an LED lamp is adopted; a heater is arranged on the outer wall of an air outlet pipe of the LED lamp, a temperature sensor is mounted on the outer wall of a glass container, and a PLC control system is arranged; when the temperature sensor senses that the internal temperature of the glass container does not change, this shows that the LED lamp dissipates heat slowly at present; the heater is controlledto heat the air outlet pipe through a PLC to promote heat conducting liquid to be evaporated to get into an airbag to make the airbag larger, the area of the airbag is increased, cooling is accelerated, and more cooled heat conducting liquid is generated and flows back through a return pipe. Accordingly, heat dissipation of the LED lamp is promoted.

Description

technical field [0001] The invention belongs to the field of improving the service life of optoelectronic devices, and in particular relates to a method for improving the service life of LED lamps. Background technique [0002] Light-Emitting Diode Light-EmittingDiode, LED, is a semiconductor component. At the beginning, it was mostly used as indicator lights, display light-emitting diode boards, etc.; with the emergence of white LEDs, it was also used as lighting. In the LED lighting system, the decisive factor that determines its luminescence and service life is the heat dissipation of the chip, so the heat dissipation of LED lamps has always been the focus of attention. The aluminum heat dissipation structure used in the early days used multiple heat sinks to make waves or folds to increase the contact area with the air, thereby reducing the chip temperature. With the increase of LED chip power, heat production also increases, and the original aluminum heat dissipation ...
