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.
