Abstract
The utility model discloses a light-mixing LED (light emitting diode) display screen, which comprises an LED module. The LED module comprises a PCB (printed circuit board) and a plurality of LED units which are sequentially arranged on the PCB; a plurality of mounting positions are sequentially arranged on the PCB; the LED units are fixedly arranged on the PCB through the mounting positions; the mounting positions are of hollow circular-truncated-cone structures, and the height of the mounting positions is greater than the height of the LED units; a light mixing plate covers the PCB; a light mixing pin which can be inserted into each mounting position is formed on one side of the light mixing plate close to the PCB; and the side of the light mixing plate far away from the PCB is arched. According to the utility model, the light mixing plate is used for scattering the light emitted from the LED units, so that the light emitted from the LED units is scattered under the function of the light mixing plate, the lighting region and light mixing region of the LED units are enlarged, the dark space area is reduced, the uniformity of screen brightness is improved, and the display effect can be enhanced.
Description
Technical field
The utility model belongs to the LED display technical field, is specifically related to a kind of light-mixed type LED display.
Background technology
Development along with the LED technology, the application of LED display is also more and more extensive, especially outdoor display screen is widely used in station, harbour, airport, market, hospital, bank and other public place, is used for display graphics, literal, letter and various animation.Existing LED display generally comprises some LED unit of arranged in sequence on pcb board and the described pcb board, usually the spacing between the LED unit is more than or equal to the size of LED unit itself, when the LED unit is lighted, brighter in the middle of its light-emitting zone presents, the feature that the edge is darker.Outside light-emitting zone, there is non-luminous dark space, thereby causes picture disply discontinuous, affect display effect.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of light-mixed type LED display is provided, and it can avoid dark space in the light-emitting zone, has strengthened display effect.
The technical scheme that the utility model adopts is: a kind of light-mixed type LED display, comprise led module, this led module is by some LED cell formations of arranged in sequence on a pcb board and the described pcb board, described pcb board is provided with the installation position of some arranged in sequences, described LED unit is fixed on the described pcb board by above-mentioned installation position, described installation position is the hollow round table structure, and the height of described installation position is greater than the height of described LED unit, be coated with a light mixing plate on the described pcb board, described light mixing plate is provided with the mixed light pin that can fill in described installation position near a side of described pcb board, and described light mixing plate is arc away from a side of pcb board.
As preferably, the bottom surface diameter that described installation position and pcb board are affixed is less than the diameter of its another bottom surface.
The beneficial effects of the utility model are: the utility model comes the light of scattering LED unit emission by light mixing plate, the light of LED unit emission is scattered under the light mixing plate effect, enlarge light-emitting zone and the mixed light zone of LED unit, reduce the dark space area, improve the homogeneity of picture brightness, strengthened display effect.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, pcb board; 2, LED unit; 3, installation position; 4, light mixing plate; 5, mixed light pin.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of light-mixed type LED display, comprise led module, this led module is made of some LED unit 2 of arranged in sequence on a pcb board 1 and the described pcb board 1, described pcb board 1 is provided with the installation position 3 of some arranged in sequences, described LED unit 2 is fixed on the described pcb board 1 by above-mentioned installation position 3, described installation position 3 is the hollow round table structure, the bottom surface diameter that installation position 3 and pcb board 1 are affixed is less than the diameter of its another bottom surface, and the height of described installation position 3 is greater than the height of described LED unit 2, be coated with a light mixing plate 4 on the described pcb board 1, described light mixing plate 4 is provided with the mixed light pin 5 that can fill in described installation position 3 near a side of described pcb board 1, and described light mixing plate 4 is arc away from a side of pcb board 1.
The utility model comes the light of scattering LED unit 2 emissions by light mixing plate 4, the light of LED unit 2 emissions is scattered under light mixing plate 4 effects, enlarges light-emitting zone and the mixed light zone of LED unit 2, reduce the dark space area, improve the homogeneity of picture brightness, strengthened display effect.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
