Lamp tube device used for lamp box of color selector

Abstract

The invention relates to a lamp tube device used for a lamp box of a color selector. The lamp tube device comprises two fixing brackets, a plurality of lamp tubes and a background plate, wherein the background plate and the plurality of lamp tubes are parallelly mounted between the two fixing brackets, a lamp panel is arranged on one side face of each lamp tube, a plurality of lamp beads are arranged on each lamp panel, the lamp tube device further comprises a plurality of air pipes and an air pump, two ends of each lamp tube communicate with each other, so that a hollow pipeline is formed, through holes are formed in the fixing brackets, the air pipes pass through the through holes, and the air pump is connected with two ends of each lamp tube through the air pipes. Compared with the prior art, the device provided by the invention has the advantages that two ends of the lamp tubes realize communicating, cooling air is delivered in, then the temperature of the lamp tubes during work isreduced, when the intensity of the light path needs to be promoted, after the power of the lamp beads is increased, the heat dissipation of the lamp beads and the lamp tubes is assisted through the flowing of the cooling air, then the temperature in a machine box is kept basically constant while the intensity of the light path is promoted, and the influences brought by high temperature are reduced.

Description

technical field [0001] The invention relates to the field of a light box of a color sorter, in particular to a lamp tube device used for the light box of a color sorter. Background technique [0002] The optical path plays an important role in the color recognition equipment. The quality of the optical path has a direct impact on the imaging effect of visual inspection. In the field of color sorter application, the detection of some materials needs to increase the strength of the optical path. At present, there are two main ways to increase the intensity of the light path: one is to increase the power of the lamp beads, that is, to increase the brightness of the light to improve the light path, but increasing the power will increase the overall temperature in the chassis, which will cause heat dissipation problems. At the same time, high temperature It will also seriously decline the service life of the lamp beads; the second is to increase the light path by adding lamps, bu...

Problems solved by technology

At present, there are two main ways to increase the intensity of the light path: one is to increase the power of the lamp beads, that is, to increase the brightness of the light to improve the light path, but increasing the power will increase the overall temperature in the chassis, which will cause heat dissipation problems. At the same time, high temperature It will also seriously decline the service life of the lamp beads; the second is to increase the light path by adding lamp tubes, but this method will affect the overall space layout of the equipment, and adding lamp tubes can only increase the irradiation surface of light, and the highest effect on light Brightness doesn't help, boost isn't noticeable
