Abstract

The utility model discloses a luminous switch which comprises a switch panel, wherein a tritium luminous pipe is arranged on the panel. The tritium luminous pipe is a high temperature resistance glass pipe which is filled with radioactivity tritium, and the inner wall of the glass pipe is smeared with a fluorescence powder coating. The panel is inwards extended with a groove integrally, the tritium luminous pipe is arranged in the groove, a notch is provided with a transparent protection cover, and the transparent protection cover and the panel are arranged on the same plane. The luminous switch provided by the utility model needs no power supply, which saves the producing cost and the operating cost. The utility model has simple structure and convenient fabrication and use, so the utility model expands the application field and situation. The utility model solves the technical problems that the dark vision occasion with no power supply can not shine continuously and the brightness is low. By using the tritium which is a kind of safe radioelement, the fabrication and the use are safe without pollution. Because the utility model adopts the tritium as the excitation substance for shining and the half life of the tritium is 12.3 years, the service life of the luminous switch of the utility model is more than 10 years, which is longer than that of common luminous switches.

Description

A kind of illuminated switch

[technical field]

The utility model relates to the mains switch field, and specifically, the utility model relates to a kind of illuminated switch.

[background technology]

The illuminated switch of prior art uses the noctovision occasion in the power supply power supply, is to convert electric field or magnetic excitation luminescent substance to by additional power source, by this material itself or fluorescence excitation material and luminous again.In use be subjected to the direct restriction of additional power source power supply.External power supply is depended in it luminous.Its power supply and power supply changeover device can not use separately in the process of using, and this will increase manufacturing cost and operating cost.The useful life of power-supply device and power supply changeover device, service condition have also limited the useful life and the service condition of luminous tube itself; And this type of illuminated switch construction complexity and consumed power, manufacturing cost is higher, and in case the damage maintenance is very difficult, usually changes whole switch because of the damage of electroluminescence device.

A kind of illuminated switch that is not subjected to power limitations is arranged at present, is to adopt photoinduced fluroscence powder (luminescent powder) luminous.Adopt the switch of fluoresent coating to need not power supply, but it is not luminous continuously, and brightness is subjected to the restriction of extraneous light power.Though cost is low, simple in structure, its luminescent lifetime is shorter, and brightness is very low.

At the prior art above shortcomings, the utility model is proposed.

[utility model content]

The utility model is at the technical problem that prior art exists, and provides a kind of and can long-term safety uses and without the illuminated switch simple in structure of consumed power.

For realizing above-mentioned utility model purpose, the technical scheme of illuminated switch provided by the utility model is conceived as follows substantially: a kind of illuminated switch, comprise a switch panel, and panel is provided with a tritium luminotron.Tritium luminotron is coated with fluorescent coating for the inner high-temperature resistant glass tube that is filled with the radioactivity tritium gas on the glass tube inwall.Described panel extends internally and is integrally formed with a groove, and described tritium luminotron is arranged in the groove, and the notch place is provided with transparent shield.

Described transparent shield and panel are in one plane.

Described tritium luminotron be embedded in panel around

The beneficial effects of the utility model are:

1, it is luminous that illuminated switch provided by the utility model utilizes radioactivity tritium gas excitated fluorescent powder, need not the power supply power supply, saved manufacturing cost and operating cost, expanded application and occasion.The noctovision occasion that has solved the non-transformer power supply is that noctilucence fluorescent material and fluorescent material can not be luminous continuously and brightness low technical problem.

2, used the radioelement of this fail safe of tritium gas, solved fail safe and pollution problem in manufacturing and the use, manufacturing and safe in utilization pollution-free.

3, owing to adopt tritium gas as the luminous material that excites, the half-life of tritium is 12.3, so more than 10 years, be that the common illuminated switch life-span is incomparable the useful life of the utility model illuminated switch.

4, simple in structure, be convenient to make and use, expanded application and scope.

Below in conjunction with accompanying drawing the utility model embodiment is described in detail:

[embodiment]

Fig. 1 is the utility model structural representation, Fig. 2 be Figure 1A-A to view, Fig. 3 is an I portion enlarged drawing among Fig. 2.As shown in Fig. 1, Fig. 2, Fig. 3, other structure of the utility model illuminated switch is identical with general common switch, comprise a switch panel 1, panel 1 extends internally and is integrally formed with a groove 2, and the notch place is provided with and panel 1 transparent shield 3 in one plane.Be provided with a tritium luminotron 4 in the groove 2, tritium luminotron 4 is coated with fluorescent coating 5 for the inner high-temperature resistant glass tube that is filled with the radioactivity tritium gas on the glass tube inwall.

Fig. 4 is the structural representation of another embodiment of the present utility model, as shown in Figure 3, around switch panel 1, adopt the mode of inlaying directly tritium luminotron 4 to be embedded in the panel 1, present embodiment tritium luminotron 4 has the identical structure with embodiment 1, for inside is filled with the high-temperature resistant glass tube of radioactivity tritium gas, be coated with fluorescent coating 5 on the glass tube inwall.

Those skilled in the art can carry out other change and modification after reading the utility model patent specification, but these changes and modification are all within the claim protection range that the utility model awaits the reply.
