Abstract

The utility model discloses an ultrathin light-emitting device for an elevator button, comprising a light-emitting part (2) and a light counterbalancing part (1). The light-emitting part is arranged on one side of the side edge of the light counterbalancing part so as to be combined with the light counterbalancing part; only the upper light-emitting surface and the lower light-emitting surface of the light counterbalancing part can transmit light, and the other four side edges are all covered by reflective materials; light emitting directions of the upper light-emitting surface and the lower light-emitting surface of the light counterbalancing part face to the side surfaces of the light counterbalancing part, and light emitted from the upper light-emitting surface and the lower light-emitting surface is counterbalanced through the reflection of the four side edges. The utility model can effectively reduce overall thickness of the light-emitting part to be less than 2 mm, can make the design of an ultrathin elevator button possible, and can effectively reduce the number of LEDs to two so as to reduce material cost and energy consumption.

Description

A kind of ultra-thin light-emitting device of elevator button

Technical field

The utility model relates to a kind of ultra-thin light-emitting device of elevator button.

Background technology

The luminous component of existing elevator button is by LED (light-emitting diode, light-emitting diode) luminous component and even light partly constitute, because button is done thinner and thinner, thickness requirement to luminous component is also more and more harsher, traditional improving one's methods is to select for use smaller and more exquisite LED to make luminous component and select thin more even luminescent material for use, but also has been difficult to have breakthrough aspect thickness again; For guaranteeing the even of even light, must adopt the LED (generally using 4) of sufficient amount, energy-conservation inadequately.

The utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of ultra-thin light-emitting device of elevator button.

The utility model is achieved through the following technical solutions: a kind of ultra-thin light-emitting device of elevator button, comprise luminous component and even light part, even light partly has the side surface part that receives behind the light that luminous component sends in inner daylighting, after the light that luminous component sends is directed into even light part, substantially press the right angle orientation reflection by reflecting surface, these reverberation are scattered after the material scattering luminous by even light part, it is characterized in that even light part is except two light-emitting area printing opacities up and down, all the other sides material that all is reflected covers, and the mode that luminous component adopts the side to install combines with even light part.

The ultra-thin light-emitting device of aforesaid elevator button, it is characterized in that described luminous component is installed in a side of the side of even light part, the light emission direction of luminous component is facing to the side surface part of even light part, after then light sends from luminous component, by the reflection of 4 sides, send uniform light.

The beneficial effects of the utility model are: the utility model can effectively reduce the integral thickness (can accomplish that 2mm is following) of luminous component, for the design of thin more button provides possibility, and can effectively reduce the quantity (using 2 gets final product) of LED, reach the purpose that reduces Material Cost and energy consumption.

Fig. 2 is the upward view of Fig. 1;

Fig. 3 is the right view of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail:

With reference to Fig. 1-3, a kind of ultra-thin light-emitting device of elevator button, comprise luminous component 1 and even light part 2, described even light partly is light guide plate, this light guide plate has the side surface part that receives behind the light that luminous component sends in inner daylighting, after the light that luminous component sends is directed in the light guide plate, press the right angle orientation reflection substantially by reflecting surface, and by scattering film 3 that these reflection light diffusings are luminous by the end face of light guide plate.

Described luminous component 1 is LED, the mode that LED adopts the side to install, it is the side that LED is installed in the side of even light part, even light part is except two light-emitting area printing opacities up and down, and all the other 4 sides material that all is reflected covers, and the light emission direction of LED is facing to the side surface part of light guide plate, after light sends from LED, by the reflection of 4 sides, send uniform light, thereby improved the utilance of light greatly.

Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection range of the present utility model.

Claims
