Description

Mains switch

Technical field

The utility model relates to a kind of mains switch, more particularly, relates to a kind of mains switch that light-emitting diode is installed.

Background technology

Normally used mains switch generally is made of mains switch body and switch panel, and a shift knob is installed on the mains switch body, and by being opened in the outstanding switch panel in hole on the switch panel, so that the on off operating mode of power supply is controlled.But therefore this mains switch can be difficult to accurately search out the position of its shift knob owing to there is not position indicator in the time need using night, make troubles to the user.Therefore, some follow-on mains switches have also appearred in the market.

For example, in utility model patent CN2612046Y, put down in writing a kind of night vision mains switch.This mains switch comprises mains switch body, switch panel and is installed on the Switch main body and by being opened in the shift knob of the outstanding switch panel in hole on the switch panel.In addition, two light-emitting diodes also are housed on Switch main body.When mains switch was in interrupt status, lumination of light emitting diode was so that the user accurately searches out the position of the button of mains switch at night; And when mains switch was in opening, light-emitting diode was closed, with conservation of power.

But, because light-emitting diode generally is positioned at the below of switch panel, its top also is equipped with the transparent prevention plate that prevents that dust from entering sometimes, therefore most of light that light-emitting diode sent all is blocked, its brightness is generally all fainter, only reaches the usefulness that the user finds the position of push-button switch.Therefore, still there is the shortcoming that illumination range is narrow, power consumption is big in these improved mains switches.

For this reason, still need at present to develop and a kind ofly under the prerequisite that keeps original advantage, have bigger illumination range, the mains switch of more significant power savings.

The utility model content

The purpose of this utility model is to provide a kind of have bigger illumination range, the mains switch of more significant power savings.

Mains switch of the present utility model comprises: the mains switch body; Be installed in a shift knob and a light-emitting diode on the mains switch body; And the switch panel that covers the mains switch body, the light-emitting area of light-emitting diode is positioned at the position of 1 millimeter of the horizontal surface below that is not less than switch panel at least.More preferably, this light-emitting area is positioned at the position of the horizontal surface that exceeds switch panel.

In addition, the mains switch body has cube or stage body shape, and switch panel is installed in the front face side of this mains switch body.Perhaps, the mains switch body is writing board shape, and switch panel is directly installed on this flat board.

In another embodiment, the mains switch body also is provided with the device of the opening of control light-emitting diode.

Learn that by experiment the illumination space of the light-emitting diode after the improvement is obviously greater than the illumination space of traditional flush type light-emitting diode.Therefore, under the situation of using same amount electric power, can obtain better illuminating effect; And illuminate at needs under the situation of identical lighting space, employed electric power consumption is minimum.

Embodiment

Below with reference to description of drawings most preferred embodiment of the present utility model, wherein identical label is represented identical parts.

See also Fig. 1, this figure is the schematic perspective view of mains switch of the present utility model.As shown in Figure 1, mains switch is made of mains switch body 1, the switch panel 2 that covers mains switch body 1 and shift knob 3 and the light-emitting diode 4 that is installed on the mains switch body 1.Generally speaking, mains switch body 1 can have cube or stage body shape, and switch panel 2 is installed in its front face side.But mains switch body 1 also can present a writing board shape, and switch panel 2 then is directly installed on this flat board.These modification all will drop in the protection range of the present utility model.

Shift knob 3 and light-emitting diode 4 are arranged on the mains switch body 1, and by being opened in the horizontal surface 2 ' of the outstanding switch panel 2 in hole on the switch panel 2, wherein shift knob 3 plays the effect of the on off operating mode of control power supply, and light-emitting diode 4 then plays the effect into shift knob 3 illuminations.

Fig. 2 and 3 is cross-sectional schematic of mounted switch panel and light-emitting diode.Well-knownly for those skilled in the art be, the light-emitting area of light-emitting diode 4 is a linear plane, i.e. arrow among Fig. 2 and 35 light-emitting area pointed.Therefore, in order further to increase the illumination range of light-emitting diode 4, the light-emitting area 5 of light-emitting diode 4 can be arranged on the position of 1 millimeter of the horizontal surface 2 ' below that is not less than switch panel 2 at least.That is to say that the position that is provided with of light-emitting area 5 comprises the horizontal surface 2 ' below that is positioned at switch panel 2 but the zone (as shown in Figure 3) that spacing is no more than 1 millimeter zone (as shown in Figure 2) and is positioned at the horizontal surface 2 ' top of switch panel 2.But generally speaking, preferably light-emitting area 5 is set in place in the zone of the horizontal surface 2 ' top of switch panel 2.

Fig. 3 shows a most preferred embodiment of the present utility model.In this most preferred embodiment, the light-emitting area 5 of light-emitting diode 4 just is arranged in the zone of horizontal surface 2 ' top of switch panel 2, that is, light-emitting area 5 is configured to exceed the horizontal surface 2 ' of switch panel 2.Can see that the illumination space of light-emitting area 5 is obviously greater than the illumination space of traditional flush type light-emitting diode.In addition, as shown in Figure 2, even the light-emitting area 5 of light-emitting diode 4 is set in place in the horizontal surface 2 ' below of switch panel 2 but spacing is no more than in 1 millimeter the zone, experiment by the applicant as can be known, the illumination space greater than traditional flush type light-emitting diode is also wanted significantly in its illumination space.

By adopting above-mentioned setting, can obviously increase the illumination space of the light-emitting diode 4 on the switch panel 2, thereby under the situation of using same amount electric power, obtain better illuminating effect, perhaps illuminate under the situation of identical lighting space at needs, employed electric power consumption is minimum, thereby satisfies modern society about energy-efficient requirement.

In addition, circuit or the induction installation that the opening of light-emitting diode 4 is controlled can also be set in mains switch body 1, so that when not needing to use light-emitting diode 4 (for example daytime) light-emitting diode 4 is closed, thereby further strengthen the power savings of mains switch.

Though more than combining preferred embodiment has done to further specify to the purpose of this utility model, structure and technique effect, but those of ordinary skill in the art will be appreciated that, above-mentioned example only is used for illustrating, and can not be as to restriction of the present utility model.Therefore, can carry out modification to the utility model in the connotation scope of claims, for example, what can change light-emitting diode 4 arbitrarily is provided with position etc., and these modification all will drop within the desired scope of claims of the present utility model.
