Abstract
Provided is an energy-saving condensing light-emitting diode (LED) display screen. A module bottom case is connected with a printed circuit board (PCB) which is connected with an LED screen. The LED screen is provided with a plurality of rows of LED lights, every three LED lights is a group and distributed in triangle shape, and each group of lights is distributed in a row. A reflective cup cover is sleeved outside each LED light in the LED display screen. Each group of the LED lights can respectively emit light sources of different colors. The LED lights respectively emit red, green, and blue light sources. An included angle between light distribution angles of the reflective cup covers of the red and green LED lights and a horizontal plane is 55+/-1 degrees. The included angle between the light distribution angle of the reflective cup cover of the blue LED light and the horizontal plane is 37.5+/-1 degrees. The display screen carries out secondary light distribution of LEDs, collects light which is not used to fullest extent to form effective and even light beams, increases divergence angles of the light, increases a pixel area of pixel points, improves clearness and smoothness of images, lowers power of a screen body, and is energy-saving and environment-friendly, and suitable for various market demands.
Description
Technical field
The utility model relates to a kind of LED display, relates in particular to a kind of energy-conservation optically focused LED display.
Background technology
The face shield that conventional LED display adopts only plays the guard lamp pearl to display screen surface, the effect of sunshade.Yet, display screen LED luminotron itself has certain lighting angle, the general angle of outdoor light-emitting pipe is at vertical 50 degree, about level 110 degree, although outdoor conventional display screen face shield has blocked the interference of part sunshine to the brightness of screen body, but also blocked the part light of screen body itself, screen body brightness is reduced greatly, moreover because of the angle problem of luminotron itself, also some is to scatter out, do not form efficient beam and enter into human eye, become the pollution of a kind of waste and light yet.
The utility model content
Brightness reduces for existing LED display screen body, and the problem of waste and light pollution the utility model discloses a kind of optically focused LED display, adopt the optically focused face shield, by display screen LED luminotron is processed row luminous intensity distribution colour mixture, overcome the problems referred to above, have energy-efficient effect.
For achieving the above object, the technical solution of the utility model is as follows:
Energy-conservation optically focused LED display, the module drain pan is connected with pcb board, pcb board is connected with the LED screen, it is characterized in that: on the described LED screen several rows LED lamp is arranged, per three LED lamps are one group, distribution triangular in shape, every group of lamp pearl by rows, in the LED display each LED lamp overcoat the reflector face shield is arranged.
Further, the LED lamp of each group sends respectively the light source of different colours
Further, the LED lamp is rubescent look, green and blue light source respectively, and reflector face shield light distribution angle and horizontal plane angle red and green LED lamp are 55 ± 1 degree, and the reflector face shield light distribution angle of blue led lamp and the angle of surface level are 37.5 ± 1 degree.
Further, the low 1.4MM of the aspect ratio of the reflector face shield of blue led lamp height red and green LED lamp reflector face shield does not block light beam red and that green LED lamp is sent to reach.

Embodiment
In giving accompanying drawing, reflector face shield-1, pcb board-2, module drain pan-3, red LED lamp-4, green LED lamp-6, blue LED lamp-5, the light distribution angle of green LED lamp-7, the pipe arrangement angle-8 of blue led lamp, the light distribution angle of red LED lamp-9.
Has several rows LED lamp on the display screen, there are some lamp pearls in every delegation, the Led lamp is divided into respectively red LED lamp-4, green LED lamp-6, blue LED lamp-5, the Led lamp of per three different colours is one group, distribution triangular in shape, at each LED lamp reflective face shield 1 is installed, reflector face shield light distribution angle red and green LED lamp is 71 degree, and namely the angle with surface level is 55 ± 1 degree, is 35 ± 1 to spend with the angle of vertical direction, blue lamp is 105 degree, be 37.5 ± 1 degree with the angle of surface level namely, with the angle of vertical direction be 52.5 ± 1 degree, the height of blue reflector has done 1.4mm low simultaneously, the effect that reduces height is not block red light, the light beam that green light sends adopts such structure, is that the LED luminotron is carried out secondary light-distribution, collect to greatest extent the light source that does not use, make it to form efficient beam, increased the dispersion angle of light, strengthened the sharpness of elemental area and the image of pixel, smoothness, reduced simultaneously the power of screen body, more energy-conserving and environment-protective.
This product can be according to display screen installation environment position difference and the special secondary light-distribution face shield of adapted.Product comprises that outdoor series LED energy-saving light display screen is applicable to P10, P12, P16, P18, P20 etc.
How aforesaid embodiment can realize if only being used for explanation the utility model, and unrestricted the utility model is only realized with aforesaid way.Those skilled in the art carry out the change such as size, length or material and replace and still belong to protection domain of the present utility model to technical solutions of the utility model according to common practise.
