In order to obtain mixed light effect preferably, the RGB of LED device (RGB) chip adopts " one " word arrangement more, as shown in Figure 1, it (is when placing about the pin at two ends that RGB arrangements of chips direction is parallel to generally that the pin at two ends arranges, the RGB chip vertically is arranged on the LED display), mode by the surface mount welding is fixed on the LED device on the pcb board, and the welding of present SMD mostly is and places (being to place about pin) about leg.The welding manner of placing about pin can cause the optical profile of bright dipping inconsistent because thereby left and right sides scolding tin inhomogeneous makes the symmetry of surface light emitting of entire display screen descend to some extent, especially can variation during wide-angle observation, and the brightness irregularities phenomenon appears.If mount direction in the change of existing basis, be that pin is placed up and down in vertical direction and welded, the RGB arrangements of chips will become horizontal direction thereupon, when wide-angle is watched, the reflector of LED device will cover wherein or the bright dipping of two led chips, makes the mixed light poor effect.
At the problems referred to above that existing LED device exists, it is effective to be necessary to develop a kind of mixed light, and a kind of New LED device of even brightness reaches the LED display by its manufacturing.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency of arrangement that mounts the red, green, blue chip of device at conventional surface, a kind of New LED device of new led chip arrangement is provided, this New LED device application is when LED display, can improve the mixed light effect, make the bright dipping of whole LED display screen even, improve visual effect.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of New LED device, comprise: support, the pin that is installed in the led chip that is arranged in a linear on the described support and is positioned at described support both sides, it is characterized in that, described led chip is arranged point-blank at support, has the perpendicular bisector of pin one side parallel or overlap on described straight line and the support.
Preferably, the pin of described led chip and support both sides is " worker " font and is arranged on the LED device.
Preferably, the pin of described support both sides is symmetrical distribution with respect to perpendicular bisector.
Preferably, described led chip comprises a core assembly sheet at least, and every core assembly sheet comprises a red light chips, a blue chip and a green glow chip.
Preferably, the pin number of described support either side is 1.
Preferably, the pin number of described support either side is 2.
Preferably, the pin number of described support either side is 3.
Preferably, described led chip and pin are realized being electrically connected by gold thread.
In order to realize foregoing invention purpose of the present utility model, the utility model also provides a kind of LED display of making based on described a kind of New LED device, comprise: at least one described New LED device, the face shield that is used for the PCB circuit board of the described New LED device of electric connection and places described PCB circuit board top, it is characterized in that: the horizontal direction when using with described LED display is reference system, led chip orientation in the described New LED device is vertical direction, and the pin arrangements direction of either side is horizontal direction in the described New LED device.
Compared with prior art, the utlity model has following advantage:
1, the RGB chip in the LED device vertically is arranged on the display screen, about when watching display screen, thereby avoid having improved the whole LED display screen and having gone out uniformity of light because the excessive bright dipping that causes led support to cover one of them chip in visual angle makes bright dipping inhomogeneous.
2, the pin of LED device is distributed in up and down on the PCB circuit board, avoids causing the left and right sides bright dipping of whole LED display screen asymmetric because welding is uneven, has improved the symmetry of whole LED display screen bright dipping.
