Abstract

The utility model provides a radiation resistant light source device, which comprises a shell, an anti-radiation transparent board arranged at the front section inside the aforesaid shell, an installation board provided at the rear section inside the aforesaid shell, a LED light source board fixed to the aforesaid installation board, an axial flow blower arranged at the rear section of the aforesaid installation board and a drive circuit positioned at the lateral side of the aforesaid axial flow blower and connected electrically with the aforesaid LED light source board. The utility model, which takes the LED as the light source, can work for a long time under the environment of nuclear radiation. The luminance of the utility model will not be impaired due to nuclear radiation. What is more, with the advantages of energy saving, low heat radiation and no pollution, the utility model can be applied to realize better social and economic benefit under the environment of nuclear radiation.

Description

The device of anti-the radiation source
Technical field
The utility model relates to a kind of light source, refers in particular to a kind of device of anti-the radiation source.
Background technology
The existing used light source of nuclear radiation environment is ordinary light source, through the nuclear radiation exposure of short period, and the light shell outer cover blackening, brightness descends rapidly, and the life-span is shorter, and power consumption is big, and caloric value is big, needs often to change.
The utility model content
The purpose of this utility model provides a kind of energy-conservation, lower calorific value, pollution-free and the device of anti-radiation source that the life-span is long.
For reaching above-mentioned purpose, the device of anti-radiation source the of the present utility model, be characterized in comprising: shell, be arranged on the anti-irradiation transparent panel of described enclosure front side, be arranged on the installing plate of described enclosure rear side, be fastened on the LED source plate on the described installing plate, be arranged on the axial flow blower at described installing plate rear, the drive circuit that is arranged on described axial flow blower side and electrically connects with described LED source plate.
Adopt such structure, the device of anti-radiation source the of the present utility model utilizes light emitting diode as light source, therefore can under the nuclear radiation environment, work long hours, brightness can not descend because of the nuclear radiation exposure, and have energy-conservation, lower calorific value, advantage such as pollution-free, use and to obtain favorable economic benefit and social benefit at the nuclear radiation environment.
For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.
Description of drawings
Fig. 1 is the structural representation according to the device of anti-radiation source the of the present utility model.
Fig. 2 is the schematic diagram of the drive circuit of the device of anti-radiation source the of the present utility model.
The specific embodiment
Be illustrated in figure 1 as the structural representation of the device of anti-radiation source the of the present utility model, comprise: shell 1, anti-irradiation transparent panel 2, light emitting diode (being called for short LED down) light source board 3, drive circuit 4, axial flow blower 5, installing plate 6 is formed.
The transparent panel of anti-irradiation 2 is equipped with in front side in the shell 1, and installing plate 6 is arranged on the rear side in the shell 1, and led light source plate 3 is fastened on connecing on the post 7 of installing plate 6 by screw, and axial flow blower 5 is arranged on the rear of installing plate 6.Like this, by sans serif and the shell 1 fastening combination that led light source plate 3, installing plate 6 and axial flow blower 5 are combined into, drive circuit 4 is installed in the side of axial flow blower 5 and electrically connects with led light source plate 3.
The utility model adopts transparent anti-irradiated plastics to prepare into the White LED pipe as the sealing material of White LED luminous tube, and make parallel interval with this pipe and arrange, be in series in groups with three to six (or more) LED pipes, to organize the parallel connection of LED pipe more again and constitute led light source plate 3, power through 4 pairs of led light source plates of drive circuit 3 by switching power supply.
Be illustrated in figure 2 as the schematic diagram of the drive circuit 4 of the device of anti-radiation source the of the present utility model, led light source plate 3 drives in pulse width modulated mode, IC1-1 is an impulse generator, by resistance R 1, the capacitor C 1 parameter decision pulse period, IC1-2 is a shaping circuit, IC1-3, resistance R 2, capacitor C 2 is finished pulse width modulated, IC1-4, IC1-5, IC1-6 is an internal drive circuits, output signal drives triode T1 through resistance R 3, finish power supply control to led light source plate 3, the pulse sky is than degree decision LED luminous intensity, and the resistance of regulating resistance R 2 promptly changes the pulse sky than degree, finishes the brightness regulation to led light source plate 3.
The device of anti-radiation source the of the present utility model utilizes light emitting diode as light source, therefore can under the nuclear radiation environment, work long hours, brightness can not descend because of the nuclear radiation exposure, and have energy-conservation, lower calorific value, advantage such as pollution-free, use and can obtain favorable economic benefit and social benefit at the nuclear radiation environment.
Though the utility model is described with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, under the situation that does not break away from the utility model spirit, also can make the variation or the replacement of various equivalences, therefore, as long as in connotation scope of the present utility model in the scope to the variation of the foregoing description, claims that modification all will drop on the application.
