Abstract

The utility model discloses a machine visual light source, which comprises a case and a printed circuit board (PCB), wherein the printed circuit board is welded with a light emitting diode (LED) lamp, the PCB is arranged in the case, and a gap is formed between the PCB and the case. The machine visual light source is characterized in that heat conduction silicon gel is arranged in the gap part between the PCB and the case. The machine visual light source has the advantages that the structure is simple, the heat radiation rate of the machine visual slight source can be effectively improved, simultaneously, the brightness stability of the light source is enhanced, the service life is long, in addition, the power consumption is low, and simultaneously, the integral use cost of the light source can also be reduced.

Description

The machine vision light source

Technical field

The utility model relates to the quality detection system technical field, especially a kind of machine vision light source that is used for quality detection system.

Background technology

In suitability for industrialized production, intelligentized Quality Detection is generally used in the whole world, and the machine vision light source is the core component in this detection system.General machine vision light source is made up of LED lamp, pcb board and shell, and the LED lamp is welded on the pcb board, and pcb board is mounted in the metal-back.

But the heat dissipation design of most of light sources is the natural heat dissipation modes that adopt, because have the space between the pcb board of conventional light source and the metal shell, its heat-conducting mode mainly arrives metal shell through cross-ventilation and radiation delivery; Simultaneously, the surface of conventional light source metal-back is smooth, and its area of dissipation is less relatively.

Because the brightness constancy of LED lamp receives Influence of Temperature very big, when temperature was too high, the brightness of LED lamp will reduce along with the rising of temperature, but power consumption can increase gradually, and caused the decay of LED lamp, and caused the lost of life of LED lamp.

Employing at present is low with the design and the production difficulty of upper type, and cost is relatively low, but radiating efficiency is low, and temperature meeting sustainable growth causes stability of light source poor, and the life-span is short, and power consumption is high.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provides that a kind of thermal diffusivity is good, long service life and machine vision light source low in energy consumption.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of machine vision light source; Comprise shell and the pcb board that is welded with the LED lamp; Pcb board is installed and is provided with the space in the enclosure and between pcb board and the shell, and it is characterized in that: the gap between said pcb board and shell is provided with heat conductive silica gel.

The outer surface of said shell is provided with groove.

Said groove is provided with 2 at least, and distance equates between each groove, and each groove width, the degree of depth are identical.

The beneficial effect of the utility model is: simple in structure, good heat dissipation, long service life and low in energy consumption.

Compared with prior art; The gap of the utility model between pcb board and shell is provided with heat conductive silica gel and is provided with groove at the outer surface of shell; Can effectively improve the rate of heat dissipation of machine vision light source; The brightness constancy of the light source that strengthens simultaneously, long service life and low in energy consumption, the while can also be reduced the whole use cost of light source.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment, the utility model done further being described in detail.

Shown in Fig. 1-3; A kind of machine vision light source; Comprise shell 1 and the pcb board 3 that is welded with LED lamp 2, shell 1 is processed by metal material, and pcb board 3 is installed in the shell 1 and between pcb board 3 and the shell 1 and is provided with the space; Gap between pcb board and shell is provided with heat conductive silica gel 4, is provided with groove 11 at the outer surface of shell 1.Groove 11 is provided with 2 at least, and as 3 or 4, distance equates between each groove, and each groove width, the degree of depth are identical.

When carrying out the assembling of light source; After being welded to LED lamp 2 on the pcb board 3; Fill enough heat conductive silica gels 4 at the back of pcb board 3 again, and revise filling back heat conductive silica gel 4, shape and volume can be decided according to the size of the space between pcb board 3 and the shell 1; After having revised heat conductive silica gel 4 shapes, again pcb board 3 and heat conductive silica gel 4 are installed in the shell 1, the inwall of shell 1 closely is fitted on the silica gel, with screw pcb board 3 is locked in the metal shell 1 then.

When pcb board 3 produced heat, the heat of pcb board 3 can be delivered to heat on the heat conductive silica gel 4 rapidly through heat conducting mode during use; Heat conductive silica gel 4 promptly is delivered to heat on the shell 1 through heat conducting mode again; Shell 1 is delivered to heat in the air through thermal-radiating mode; Owing on shell 1, processed groove 11, make shell 1 have bigger area of dissipation, so radiating efficiency is higher, it is faster to dispel the heat.

Should be noted that at last; Above content is only in order to explain the technical scheme of the utility model; But not to the restriction of the utility model protection domain; The simple modification that those of ordinary skill in the art carries out the technical scheme of the utility model perhaps is equal to replacement, does not all break away from the essence and the scope of the utility model technical scheme.
