The led lamp circuit board with the reflection layer is characterized in that the surface on one side of the circuit board which is provided with the light-emitting diode is fixed with a reflection layer. The utility model aims to provide a novel circuit board with a reflection layer, which has higher practicality and low cost, and is mainly used in the lighting field. The utility model can provide a novel circuit board with a reflection layer, which has higher practicality and low cost, and is mainly used in the lighting field.
Description
[technical field]
The utility model belongs to a kind of led lamp driver plate that has reflector layer in field of backlights, and this wiring board can improve the brightness of the lamp plate that the led light emitting diode makes.
[background technology]
Existing backlight in the process of practical application, brightness is difficult to satisfy the requirement of TFT glass, in order to strengthen the brightness of backlight, basically all will be at external BEF bright enhancement film, realize with the brightness that improves lamp, though the brightness by BEF bright enhancement film and raising lamp promotes height backlight. cost backlight all will significantly increase, existing BEF bright enhancement film is owing to make material and production technology problem simultaneously, cause the BEF bright enhancement film to exist easy scuffing, problems such as black-white point is many, the BEF bright enhancement film has limited the speed of its popularization because the production technology problem causes its price high.Above-mentioned problem long-term existence in industry, the very effective technical solution of neither one so far.
[summary of the invention]
The purpose of this utility model provides a kind ofly to be had than high practicability, and with low cost, mainly uses the novel wiring board with reflector layer in lighting field.
In order to reach above-mentioned technical purpose, the technical solution that the utility model adopts comprises following content: a kind of led lamp driver plate that has reflector layer, be fixed with the led LED light lamp on this wiring board, it is characterized in that: the surface that described wiring board is provided with led light emitting diode one side is fixed with reflector layer.
Described reflector layer is that the reflective printing ink that is coated in PCB surface constitutes.
Described reflective printing ink is white or silver color.
Described reflector layer is for pasting the film that has reflecting coating in the circuit board, on this film with wiring board on corresponding position, led light emitting diode position be provided with through hole, the led light emitting diode is by stretching out in these through holes.
By adopting above-mentioned technical solution, the utility model has obtained following technological merit and effect: the structure that reflector layer is set in the circuit board by employing in the utility model, the light that the led light emitting diode is sent is fully reflected by reflector layer, significantly improves the brightness of illumination; By adopting the reflective printing ink coating of direct use to constitute the structure of reflector layer in the circuit board, make the making of this reflector layer simple, cost is cheaper, also can obviously improve the bond strength of reflector layer and wiring board simultaneously; Reflector layer of the present utility model in addition also can be realized by the film that stickup has the performance of giving out light, adopt this stickup to have the mode of the film of reflector layer, can enhance productivity significantly, reduce cost of manufacture simultaneously, by adjusting the position of offering of through hole on it, in the led lamp driver that can use in plurality of specifications, have with low cost, adaptable advantage.
[description of drawings]
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a cutaway view of the present utility model.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is the technological improvement of having done at the shortcoming of the BEF bright enhancement film that uses in the existing backlight, the wiring board that provides a kind of novel led LED light lamp to use, common structure all is the lamp plate that the welding of led LED light lamp is constituted in the circuit board an integral body, lamp plate is fixed on makes the led led lamp in the shell then.As depicted in figs. 1 and 2, the technological improvement of being carried out in the utility model is that the surface that wiring board 1 is provided with led light emitting diode one side is fixed with reflector layer 2.The light that utilizes reflector layer 2 will shine wiring board 1 surface fully reflects, and reaches the effect that improves lamplight brightness.
Its structure comprises following two kinds of structures, and as depicted in figs. 1 and 2, the reflector layer 2 of first kind of embodiment constitutes for the reflective printing ink that is coated in wiring board 1 surface.In order to be that reflector layer 2 has reflecting effect preferably, described reflective printing ink is white or silver color.The advantage that adopts this structure is easy to process, and reflector layer 2 and wiring board 1 bond strength height.Above-mentioned this luminescent layer 2 manufacturing process are, at first process will be carried out in dust-free workshop, at first deployed reflective printing ink, preferably use the reflective printing ink of white, certainly according to using needs also can adopt silver color or other reflective printing ink, adopt silk screen printing process that above-mentioned reflective printing ink is printed on the wiring board 1 then, in the circuit board, promptly can be made into the lamp plate in the utility model then with reflector layer 2 with the welding of led light emitting diode.
Second kind of embodiment of the present utility model, described reflector layer is for pasting the film that has reflecting coating in the circuit board, on this film with wiring board on corresponding position, led light emitting diode position be provided with through hole, the led light emitting diode is by stretching out in these through holes.Adopt this structure, can shift to an earlier date batch making and have the film of reflector layer, then by adjusting the stamping position of through hole on the film, can use in the wiring board of different size and use, so it is strong that this frame mode has adaptability, processing and fabricating is advantage easily, is fit to more use use in small lot batch manufacture.
Should be pointed out that the above specific embodiment can make those skilled in the art more fully understand the utility model, but limit the utility model never in any form.Therefore, although this specification has been described in detail the utility model with reference to drawings and Examples,, it will be appreciated by those skilled in the art that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the middle of the protection domain of the utility model patent.
