Abstract
The utility model discloses a reverse back type luminescence indication switch for decorative lamps. A luminescence device on the switch is installed in the switch; an indication lamp eyelet is not arranged on a switch panel; the profile of the switch is set off only by residual light. Thus, the position of the switch can be easily found in the dark. The utility model does not glare and does not influence sleep.
Description
The utility model relates generally to a kind of lamp switch, particularly has the switch of indicator light.
Known switch generally is installed on the indoor wall.In order to solve the problem that is not easy to find immediately the position of the switch in the inlet chamber at night, on the switch that has indicator light is housed.For example the positions of panels perforate at switch is provided with neon lamp or light-emitting diode, be very easy to find the position of switch so in the dark, but so also bring certain problem, for example the light of indicator light is dazzling especially in the dark, be unfavorable for very much some people's sleep, the so-called favourable fraud that also has to light sensitive.The utility model is to address the above problem and produces.
The purpose of this utility model then is to provide a kind of luminous indication decorative lamp of reverse back type switch that does not influence sleep.
For achieving the above object, scheme of the present utility model is: the light-emitting device of switch is installed in switch inside, does not have the indicator light eyelet on the switch panel.
Adopt such scheme, dazzling light-emitting component is hidden in switch enclosure, only depend on faint surplus light to set off out the position of switch, thereby realized the purpose of this utility model.
Below in conjunction with diagram and embodiment this programme is described in more detail.
Fig. 1 is the front view of the luminous indication decorative lamp of reverse back type switch;
Fig. 2 is the light-emitting device line map of the luminous indication decorative lamp of reverse back type switch.
Be illustrated in figure 1 as the embodiment of a described switch of scheme.This switch is made up of panel (1) and switch enclosure (2), and switch enclosure is equipped with the contact element that is made by metal in (2).The application's object of protection is applicable to the switch of any structure.Light-emitting device (3) is installed in switch inside, on panel (1), do not establish eyelet, present embodiment is installed in light-emitting device the position of close switch side, therefore light spills from the slit (4) of switch enclosure and switch room, extremely faint, can't see daytime, only night dim light can blur and see, this not dazzling influence sleep with regard to being enough in the dark the indicator cock position.
In fact as long as light-emitting device is equipped with in switch inside, see through very thin plastic cover flaggy, still can demonstrate the position in the dark.
Fig. 2 is described to be concrete light-emitting device line map, and described light-emitting device comprises that a light-emitting diode (5) is connected in series with a load resistance (6), a diode, and two ends are again with switch (7) and connect.Above-mentioned circuit has reduced a half voltage by the diode halfwave rectifier, by the resistance of adjusting load resistance light-emitting diode is operated in the suitable electric current and voltage again, makes the light-emitting device reliably working, and when load (8) was worked, light-emitting device extinguished.In addition, this light-emitting device, is not indicated as filament break when breaking down in load (8) yet, so the effect that shows fault is arranged.
Said apparatus has overcome the defective of prior art, and can be the warmth service of family better, will be subjected to people's welcome.
In sum, the utility model is effective.
Claims (2)
1, the luminous indication decorative lamp of reverse back type switch is characterized in that: the light-emitting device on the switch is installed in switch inside, does not have the indicator light eyelet on the switch panel.
2, the luminous indication decorative lamp of reverse back type according to claim 1 switch is characterized in that: described light-emitting device comprises that a light-emitting diode is connected in series with a load resistance, a diode, and two ends are again with switch and connect.
