Description

Charger and light equalizing plate for status indication

Technical Field

The utility model relates to a charger field, in particular to charger and be used for the equal worn-out fur of state indication.

Background

Most charging devices (e.g., mobile power supplies, chargers, etc.) in the prior art use a common LED for power indication or operation status indication, and the display area is usually small. If the whole surface of the product body is used for lighting indication, the common LED lamp cannot meet the application requirement, on one hand, a plurality of LEDs are required to be used according to the actual lighting area, so that the cost is increased, and on the other hand, when the plurality of LEDs are used, the phenomenon that the brightness of a light source is not uniform enough is caused.

SUMMERY OF THE UTILITY MODEL

The utility model provides a charger and the board that equalizes that is used for status indication to solve at least one above-mentioned technical problem.

To solve the above problem, as an aspect of the present invention, there is provided a light equalizing plate for status indication, including: last diffusion piece, prism piece, diffusion piece, light guide plate and the reflector plate down set gradually from top to bottom, be formed with a plurality of semi-transparent diffuse reflection portion that are the array and arrange on the upper surface and the lower surface of light guide plate.

Preferably, the semi-transmissive diffuse reflection part is printed on the light guide plate by a screen printing method.

Preferably, the semi-transparent diffuse reflection part is formed by laser etching.

Preferably, the semi-transmissive diffuse reflection part has a circular shape.

Preferably, a light shielding plate is disposed at a circumferential edge of the light guide plate.

The utility model also provides a charger, including shell, circuit board, light-passing board and the foretell board that all shines that is used for status indication, the light-passing board, all shinning board and circuit board set gradually from top to bottom, the light-passing board is installed the opening part of shell.

Since the technical scheme is used, the utility model provides a be provided with semi-transparent diffuse reflection portion on the light guide plate for the total reflection characteristic of the inside light of entering light guide plate is destroyed, makes light can follow the upper and lower surface of light guide plate and jets out, thereby has improved the homogeneity of display area light source luminance, can use in the scene that needs use large tracts of land light source to instruct operating condition, has avoided adopting a plurality of LEDs to lead to the cost to increase, the inhomogeneous problem of luminance.

Detailed Description

The embodiments of the invention are described in detail below, but the invention can be implemented in many different ways, which are defined and covered by the claims.

As an aspect of the present invention, there is provided a light equalizing plate for status indication, including: last diffusion sheet 1, prism piece 2, diffusion sheet 3, light guide plate 4 and reflector plate 5 down set gradually from top to bottom, be formed with a plurality of semi-transparent diffuse reflection portion 6 that are the array and arrange on the upper surface and the lower surface of light guide plate 4.

Preferably, the semi-transmissive diffuse reflection part 6 is printed on the light guide plate 4 by a silk screen printing method.

Preferably, the semi-transparent diffuse reflection part 6 is formed by laser etching.

Preferably, the semi-transmissive diffuse reflection part 6 has a circular shape.

Preferably, a light shielding plate is disposed at a circumferential edge of the light guide plate 4.

The utility model discloses in, the light guide plate adopts silk screen printing net or laser technique to form intensive latticed light spot (semi-transparent diffuse reflection portion 6) on PMMA PC or other high-transparent materials, and in particular, light spot density is relevant with concrete demands such as light guide plate thickness, practical application, and the setting of semi-transparent diffuse reflection portion 6 for the total reflection characteristic of the inside light of entering light guide plate is destroyed, makes light can follow the upper and lower surface of light guide plate and jets out. In addition, single-side light guiding is adopted in most light indication application scenes, and the light reflecting sheet is used for reflecting light rays emitted from the bottom surface back to the light transmitting surface. The shading plate is used for shading the edge of the light guide plate and ensuring that light emitted by the light source cannot leak out of the side face of the light guide plate. The diffusion sheet is used for atomizing the light source and concentrating the light rays with different angles to the front side for emitting light. When the LED light source is used, the LED light source is arranged on the outer side of the light guide plate and can be a light emitting source such as a common monochromatic LED, an analog color RGB LED and an integrated digital control full-color LED, wherein the light emitting source can be sealed into a whole with the side face of the light guide plate through a narrow strip type PCB.

The utility model also provides a charger, including shell 7, circuit board 8, light-passing board 9 and foretell equal worn-out fur 10 that is used for the status indication, light-passing board 9, equal worn-out fur 10 and circuit board 8 set gradually from top to bottom, light-passing board 9 is installed shell 7's opening 11 department.

The circuit board 8 and the light equalizing plate 10 carried by the circuit board are connected in a welding mode and then connected with the internal hardware of the product as a whole, and a clamping groove with a proper size and a large-area welding disc can be designed according to the stacking mode of the internal hardware of the product to ensure the connection stability. The light-transmitting plate 9 can be designed with static display contents and is embedded into the shell 7 of the product in a buckling mode.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
