Abstract
The utility model discloses an LED (light-emitting diode) display special for an elevator. The LED display comprises a PCB (printed circuit board) and a reflection cover arranged on the PCB, wherein connecting gold fingers are arranged on the two sides of the PCB; a surface-mounted LED electrically connected with the PCB is arranged in each frame of the reflection cover; an epoxy resin adhesive for packaging the surface-mounted LED is also arranged in each frame of the reflection cover; a black printing ink layer is arranged on the reflection cover. According to the LED display, light emitted by the LEDs is soft, and the edges of light spots are clear, so that the visual fatigue of people can be effectively reduced; the display is manufactured by tested and separated surface-mounted LEDs, so that the display consistency of a product can be ensured, and the yield of the product is greatly increased.
Description
Technical field
The utility model relates to a kind of light-emitting diode display being exclusively used on elevator control panel.
Background technology
Along with scientific and technological development, LED display device is used widely.On the control panel of current all kinds of elevators, all adopt light-emitting diode display to indicate floor, up and down or the information such as switch.Because LED light is clear, can select different colors, and power saving, users' favor obtained.Light-emitting diode display is located at circuit onboard led by wiring board, dot matrix way conventionally and the reflection cap that covers in above matrix LED forms an integral module structure.Along with the increase of pile, the light-emitting diode display being exclusively used on all kinds of elevators also gets more and more, and the deficiency of light-emitting diode display starts to display.
The light-emitting diode display using on existing elevator, luminous mildness is not good enough, easily makes people's eyes feel tired; In addition, the light source of installing is LED bare chip, while making display due to employing LED bare chip, also relate to more processing technology, therefore can leave some defects, after causing display to use a period of time, indivedual LED just break down, thereby need to change monoblock display apparatus module, therefore make maintenance cost increase.
Summary of the invention
The utility model, in order to solve above-mentioned technical matters, proposes the special light-emitting diode display of a kind of luminous elevator soft, reliable product quality.
The special light-emitting diode display of a kind of elevator the utility model proposes, it comprise both sides with connect golden finger PCB, be located at the reflection cap on this PCB.In each frame of this reflection cap, be provided with the paster LED being electrically connected with PCB, be also provided with the epoxide-resin glue of the described paster LED of encapsulation in the each frame of reflection cap, described reflection cap upper surface is provided with black ink layer.
Preferably, described epoxide-resin glue is the epoxide-resin glue that mixes diffusant.
Described paster LED is that glow color is at least redness, yellow, blueness, green and a kind of paster LED of white.
The bottom surface of described PCB is provided with protection ink layer.
The color of described protection ink layer is black, green or white one.
The utility model adopts, at reflection cap upper surface, one black ink layer is set, and encapsulates paster LED with the epoxide-resin glue that mixes diffusant, and this makes LED luminous soft and keep luminous point edge clear, can effectively improve the fatigue of people's vision.The more important thing is the paster LED making display adopting after test, sorting, can guarantee the consistance that product shows, the acceptance rate of product is improved greatly, effectively reduce the mass defect that LED stays because of following process link, guarantee the fiduciary level of product quality, therefore made maintenance cost greatly lower.
Accompanying drawing explanation
Fig. 1 is the utility model preferred embodiment front schematic view;
Fig. 2 be Fig. 1 A-A to cross section schematic diagram;
Fig. 3 is the front schematic view of the utility model embodiment.
Embodiment
As shown in Figure 1 and Figure 2, the special light-emitting diode display of elevator that the utility model preferred embodiment provides, it comprises: PCB 1, be located at PCB both sides as the connection golden finger 6 of pegging graft, be located at the reflection cap 2 of dot matrix on this PCB 1.In the each frame of this reflection cap 2, be provided with the paster LED 4 being electrically connected with PCB 1, be also provided with the epoxide-resin glue that mixes diffusant 3 of the described paster LED 4 of encapsulation in the each frame of reflection cap 2, reflection cap 2 upper surfaces are provided with black ink layer 7.Can select as required to send the paster LED 4 of redness, yellow, blueness, green and any light of white, also can select to send the paster LED 4 by red, yellow, blue, green and the light that white random colour combines.Also be provided with protection ink layer 5 in the bottom surface of PCB 1.The color of protection ink layer 5 is to select black, green or white any.
As shown in Figure 3, the utility model the second embodiment, the structure of its structure and above-mentioned preferred embodiment is basic identical, and difference is that arranging of paster LED 4 is different.In the present embodiment, paster LED 4 is arranged to figure---and two arrows dorsad, can be used for indicating elevator door and open.As required, paster LED 4 is also arranged to other figures, as, indicating elevator door is closed, inferior on elevator.
At reflection cap upper surface, one black ink layer is set, and encapsulates paster LED with the epoxide-resin glue that mixes diffusant, this makes LED luminous soft and keep luminous point edge clear, can effectively reduce the fatigue of people's vision.Adopt the paster LED after test, sorting to make display, can guarantee the consistance that product shows, the acceptance rate of product is improved greatly.
Above specific embodiment is only in order to illustrate structure of the present utility model, and those of ordinary skill in the art can make various deformation and variation under design of the present utility model, and these distortion and variation include within protection domain of the present utility model.
