Abstract
The utility model discloses a machine vision light source which comprises a shell and a PCB (printed circuit board) welded with an LED (light-emitting diode) lamp, wherein the PCB is mounted in the shell and a gap is reserved between the PCB and the shell. The machine vision light source is characterized in that the back side surface of the shell is provided with a radiator with an electric driver; a temperature sensor is arranged in the gap; and the temperature sensor is electrically connected with a temperature controller which is used for controlling the starting and stopping of the electric driver. The machine vision light source is simple in structure, long in service life and low in power consumption; and by using the machine vision light source, the heat radiating rate of the light source is greatly improved, the brightness stability of the machine vision light source is enhanced, and simultaneously, the whole use cost can be reduced.
Description
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 system generally uses 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 and shell, and the LED lamp is welded on the PCB, and pcb board is mounted in the metal-back.
But the heat dissipation design of most of machine vision light sources is the natural heat dissipation modes that adopt, and promptly adopts the natural radiation heat radiation in air of light source metal-back.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, reduces the machine vision light source of light source power 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; It is characterized in that: on the dorsal surface of said shell, be provided with the radiator of a charged drive unit, be provided with a temperature sensor in said gap, temperature sensor is electrically connected with the temperature controller of control electric driver start and stop.
Said radiator comprises a housing and an exhaust fan, and exhaust fan is installed in the housing, is provided with the air outlet of exhaust fan in the both sides of housing, on air outlet, is provided with the exhaust grid.
Be provided with fin in the housing of said radiator.
Two sides at said shell are equipped with groove, are provided with the heat radiation groove at the shell dorsal surface.
The beneficial effect of the utility model is: simple in structure; Through radiator is set, can improve the rate of heat dissipation of machine vision light source greatly, strengthen the brightness constancy of machine vision light source; Reaching under the condition of same brightness; The operating current and the voltage of light source are relatively low, and long service life and low in energy consumption can reduce whole use cost simultaneously.
Two sides at shell are equipped with groove, and dorsal surface is provided with the heat radiation groove, can increase the area of dissipation of shell.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the cutaway view of A-A direction among Fig. 2.
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 comprises shell 1 and the pcb board 3 that is welded with LED lamp 2; Pcb board 3 is installed in the shell 1 and between pcb board 3 and the shell 1 and is provided with the space; Shell 1 is processed by metal material, is equipped with groove 11 in the two sides of shell 1, is provided with heat radiation groove 12 at shell 1 dorsal surface; So can increase the radiating surface of shell 1, help heat radiation.On the dorsal surface of shell 1, be provided with the radiator 5 of a charged drive unit; Gap between pcb board 3 and shell 1 also is provided with a temperature sensor 6; Temperature sensor 6 is electrically connected with a temperature controller, and temperature controller is connected with the electric driver circuit, the start-stop of control electric driver.
The operation principle of the utility model is: when pcb board produces heat; The temperature sensor that is arranged on space between pcb board and the shell can be delivered to current temperature temperature control controller; When temperature reaches preset temperature, temperature controller will start cooling device automatically and carry out forced heat radiation.
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.
