Abstract
Disclosed in the utility model is a uniform-luminescence SMD surface mount unit-based backlight comprising a PCB board, an SMD wafer and a lamp cup. The SMD wafer is fixed at the center of the lamp cup; and the PCB board is provided with a positive line and a negative line, wherein the positive line and the negative line are consistent with the polarity of the SMD wafer. According to the scheme, the SMD wafer is fixed at the center of lamp cup and the PCB board is provided with the positive line and the negative line, wherein the connection direction of the positive line and the negative line is opposite to the polarity direction of the SMD wafer. Therefore, the uniform luminescence of the backlight is realized and the light emitting effect is good.
Description
Technical field
The utility model relates to backlight, the backlight of a kind of luminous even SMD Surface Mount relating in particular to.
Background technology
On market, yellow green patch-type SMD wafer is all reversed polarity, and die bond position is a side in Lamp cup partially, causes when luminous the bright side of a side dark, the bad improvement of bright inequality.
Therefore, there is defect in prior art, needs to improve.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of luminous even, the backlight of the luminous even SMD Surface Mount that illumination effect is good.
The technical solution of the utility model is as follows: a kind of backlight of luminous even SMD Surface Mount, comprise pcb board, SMD wafer and Lamp cup, described SMD wafer is fixed on the center of described Lamp cup, and, described pcb board arrange closure respectively with anodal circuit and the negative pole circuit of described SMD wafer opposite polarity directions.
Adopt such scheme, the utility model is by being fixed on SMD wafer the center of Lamp cup, and, by pcb board is set, and on pcb board, arrange closure respectively with anodal circuit and the negative pole circuit of SMD wafer opposite polarity directions, the cathode and anode directions that changes SMD wafer by anodal circuit and negative pole circuit, makes the both positive and negative polarity position of backlight with existing identical; And, can make backlight luminous evenly, illumination effect is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The present embodiment provides a kind of backlight of luminous even SMD Surface Mount, and described mould backlight can improve the problem of existing backlight luminance nonuniformity.
As shown in Figure 1, backlight comprises pcb board 103, SMD wafer 102 and Lamp cup 101, SMD wafer 102 is fixed on after Lamp cup 101, again according to being fixed on pcb board 103, and, SMD wafer 102 is fixed on the center of Lamp cup 101, and, on pcb board 103, arrange simultaneously closure respectively with anodal circuit and the negative pole circuit of described SMD wafer 102 opposite polarity directions.
For example, SMD wafer is placed on behind the center of Lamp cup, SMD wafer becomes positive polarity by original negative polarity, the both positive and negative polarity position of backlight changes, so, by at pcb board, arrange closure respectively with anodal circuit and the negative pole circuit of the SMD wafer opposite polarity directions of positive polarity, anodal circuit is connected with SMD wafer respectively with negative pole circuit, thereby can change the cathode and anode directions of positive polarity SMD wafer, make the positive extreme direction of backlight identical with original negative polarity SMD wafer with negative pole direction, the installation link position that keeps its original positive pole and negative pole, can also make brightness disproportionation and bad the improving of backlight, backlight is lighted rear cost effectiveness and is improved, quality-improving.
And for example, because SMD wafer becomes positive polarity, make its positive pole by the left end that is arranged on pcb board, become the right-hand member that is arranged on pcb board, so, anodal circuit can be set, and change the direction of anodal circuit, guided to the right-hand member of pcb board, thereby make the anodal position of backlight with originally identical.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
