Abstract

The utility model discloses a back sign wall flush mounting plate of switch, it includes backlight source, printing opacity polaroid and shading material layer from the inboard outside of flush mounting plate in proper order, and backlight source includes the L ED lamp of at least a colour and forms the return circuit with switching power supply, and the shading material layer is provided with the identification character of fretwork, the utility model discloses with this flush mounting plate of switch assembly back on wall switch base, need not add in addition to label and mark the switch name, also can demonstrate a plurality of switch button's name and be convenient for discern in the environment of dark, through the different operating condition of the differentiation switch of different colours to guide the exact position of pressing.

Description

Back sign wall flush mounting plate of opening

Technical Field

The utility model relates to a wall flush mounting plate of switch technical field, especially a back sign wall flush mounting plate of switch.

Background

The existing wall switch has no corresponding application position name identification in the case of multiple keys. After the wall switch is installed, a consumer adds a label to mark the position corresponding to the name. In this case, the name of the multi-key cannot be recognized in a dark environment, and the on or off state of the wall switch cannot be displayed in a dark environment. Other switches with indicator lights are used in electrical switches, and have very few applications in domestic wall switches.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to the not enough of above-mentioned prior art, a back sign wall flush mounting plate of switch is provided.

In order to solve the technical problem, the technical scheme adopted by the utility model is that the back surface identification wall switch panel comprises a backlight source, a light-transmitting polaroid and a shading material layer from the inner side to the outer side of the switch panel in sequence, wherein the backlight source comprises L ED lamps with at least one color and forms a loop with a switch power supply, and the shading material layer is provided with hollow identification characters.

In the above technical scheme, a light diffuser is further arranged between the light-transmitting polarizer and the backlight source.

In the above technical scheme, the light-shielding material layer is a light-shielding coating layer coated on the surface of the light-transmitting polaroid, and the uncoated part of the surface of the light-transmitting polaroid forms the identification character.

In the above technical scheme, the light-shielding material layer is a light-shielding material panel, and the light-transmitting polarizer is arranged on the back surface of the light-shielding material panel.

In the above technical scheme, the light-transmitting polarizer is a negative display light-transmitting polarizer.

The utility model has the advantages that:

1) the whole combined structure is simple and reliable.

2) After the switch panel is assembled on a wall switch base, the switch name is marked without additionally labeling.

3) The names of the plurality of switch keys can be displayed in a dark environment and are convenient to identify.

4) The correct pressing position is guided by distinguishing different working states of the switch through different colors.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

In the figure, 1, a backlight source; 2. a light-transmitting polarizer; 3. a light-shielding material layer; 4. a light diffuser; 5. the character is identified.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in figure 1, the back surface identification wall switch panel sequentially comprises a backlight light source 1, a negative display light-transmitting polaroid 2 and a shading material layer 3 from the inner side to the outer side of the switch panel, wherein the backlight light source 1 comprises L ED lamps with at least one color and forms a loop with a switch power supply, and the shading material layer 3 is provided with hollow identification characters 5. for example, L ED lamps with two colors have the identification effect that the switch displays one color in an open state and displays another color in a close state, and the identification is convenient for a user to distinguish the switch state.

Specifically, a light-diffusing sheet 4 is arranged between the light-transmitting polarizer and the backlight light source, and light is uniformly diffused by combing the light-diffusing sheet, so that displayed character light is not dazzled and concentrated, and is softer at night.

Specifically, in an embodiment of the light-shielding material layer 3, the light-shielding material layer is a light-shielding coating layer coated on the surface of the light-transmitting polarizer, and the uncoated part of the surface of the light-transmitting polarizer forms the identification character; a switch panel shell can be additionally arranged. In another embodiment of the light-shielding material layer, the light-shielding material layer is a light-shielding material panel, and the light-transmitting polarizer is adhered to the back surface of the light-shielding material panel through an adhesive layer, which may be OCA optical adhesive.

The utility model discloses a theory of operation:

the backlight source is powered by the switching power supply to be lightened, and an L ED lamp of the backlight source emits light and uniformly radiates the light through the light-diffusing sheet to be emitted from the hollow identification characters through the polarizer to form the luminous identification characters.

The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention.
