Specific embodiment
The purpose of the present invention can be achieved through the following technical solutions：
A kind of ultra-thin LED advertisement cabinet, referring to Fig. 1-7, including outline border 1, light source 2, light guide plate 3, backboard 4, screw 5；
Backboard 4 is provided on the outline border 1, backboard 4 is mounted on 1 lower surface of outline border by screw 5；4 inner sidewall of backboard
It is provided with light source 2；Light guide plate 3 is provided in the outline border 1；
3 lower surface of light guide plate is provided with the first site 31, and 3 upper surface of light guide plate is provided with the second site 32；
The shape of first site 31 is semicircle, circular shaped lattice point, annular one of site or bar shaped salient point or more
Kind combination, the arrangement mode of the first site 31 are one of linear array, arcuate array, random number arrangement；
The shape of second site 32 is semicircle strip projected parts, semicircle strip groove, triangle strip projected parts, three
One of angular strip groove or multiple combinations, several second sites 32 are parallel to each other, two neighboring second site, 32 spacing
It is equal；
Second site 32 is vertical with the light source 2；
Extend to center first is provided on 1 inner sidewall of outline border along side 11, fixing groove 12 is arranged in 1 back side of outline border,
12 edge of fixing groove is provided with limit edge 14, and fixing groove 12, limit edge 14 and backboard 4 cooperate, and backboard 4 is embedded in fixing groove
In 12；Outline border screw hole 13 is provided on outline border 1 in the fixing groove 12；
The light source 2 is made of PCB circuit board 21, LED lamp bead 22, and LED lamp bead 22, LED is provided in PCB circuit board 21
Lamp bead 22 equally arranges；
4 lower surface of backboard is provided with limit plate 41, and limit plate 41 is rectangular shaped rim structure；The back in 41 outside of limit plate
It is provided with outwardly extending second on 4 lower surface of plate and is provided with screws of backboards hole 43, screws of backboards along side 42 along side 42, second
Hole 43 and outline border screw hole 13, screw 5 cooperate, and backboard 4 is mounted on outline border 1 by screw 5, and advertisement poster is pressed in by limit plate 41
First along side 11；
4 upper surface of backboard is provided with reflectance coating 44；Light source 2 is irradiated on reflectance coating 44, is reflected into and is led
In tabula rasa 3, under conditions of cancelling reflecting paper, the light efficiency of the flat lamp is promoted.
The working principle of the invention：
Traditional LED advertisement cabinet, advertisement poster is attached on outline border 1, and the light that the light source 2 in advertisement cabinet issues passes through light guide plate 3
The reflecting paper of 4 inside of side wall and backboard reflects light into light guide plate 3, by the optical surface reflection of multiple light guide plate 3, reflects,
Finally go out illumination from 3 front of light guide plate and be mapped to diffuser plate, then is projected through advertisement poster；
Reflecting paper and diffuser plate in tradition LED advertisement cabinet increase the thickness of advertisement cabinet, and multiple reflections, refracting process
Middle energy loss is huge；And the present invention uses and is cooperated by outline border 1 and backboard 4, fixation of advertisement is drawn；The light warp issued than light source 2
It crosses reflectance coating 44 to be reflected on light guide plate 3, then the second site 32 being arranged on 3 through the light guide plate, direct irradiation is wide after diffusion
Announcement is drawn, and the energy loss without multiple reflections, refraction, therefore the advertisement cabinet has very high light efficiency.
The advertisement cabinet promotes light-emitting uniformity by light guide plate 3, to reduce the diffusion being arranged above conventional light guiding plate 3
Plate, reduces the production cost of the advertisement cabinet, and the thickness of the advertisement cabinet is thinned；
The advertisement cabinet substitutes traditional reflecting paper by reflectance coating 44 by being provided with reflectance coating 44 on backboard 4,
While reducing production cost, the thickness of the advertisement cabinet is further thinned；
After the light that the light source 2 issues enters from the side of light guide plate 3, the second site of 3 lower surface 32 is reduced through the light guide plate
The total reflection of 3 upper surface of light guide plate increases light diffusion angle and range of scatter of the incident light in light guide plate 3, through the light guide plate 3 table
After the multiple reflections of face, projected behind the second site 32 amendment direction of 3 lower surfaces through the light guide plate, the second site 32 has cohesion light
Line promotes frontal luminance, corrects light direction, promotes the light-emitting uniformity of the flat lamp.
The present invention provides a kind of ultra-thin LED advertisement cabinet, have the characteristics that thickness reduction, uniform in light emission, production cost are low.
Above content is only to structure of the invention example and explanation, affiliated those skilled in the art couple
Described specific embodiment does various modifications or additions or is substituted in a similar manner, without departing from invention
Structure or beyond the scope defined by this claim, is within the scope of protection of the invention.
