Abstract
The invention provides a light emitting diode (LED) lamp backlight source. The LED lamps are distributed on slopes of matrix multi-pyramid in a transparent panel base, so as to a connect conductor wiring film pre-arranged on the transparent panel base, the LED lamp lights eject to a diffuse reflection plate from various angles so as to obtain a diffuse reflection effect. The light-emitting area of the transparent panel base LED lamp is back to the front face of a lamp box and the like, a diffuse reflection reflector, which has the same area with the light-emitting area, is arranged at a certain position far away from the light-emitting area so that the point light source of the LED lamp is subjected to diffuse reflection so as to form a plane light source, then secondary diffusion reflection is formed by the transparent panel base and the scattering surface parallel to the transparent panel base, thus the light source is more uniform. According to the requirements, the light can be emitted in a form of single color, color mixture and colorful change, and the distances among the multi-pyramids and the area of the panel base can be flexibly adjusted. The LED lamp backlight source can be applied to the multiple backlight source fields, thereby achieving the purpose of energy conservation and environmental protection; the LED lamp backlight source has the characteristics of simple process, low cost and the like; and the LED lamp backlight source fills the gap of slim large and medium-sized backlight source application products, can be used in the situations such as common lamp boxes, information plates, high grade calligraphy and painting frames and the like, and has an extremely market prospect.
Description
Technical field
The present invention relates to a kind of backlight assembly of usefulness of large tracts of land brightening illumination, rice is exactly a kind of ultra thin LED lamp brightening background light source specifically.
Background technology
Present slim advertising lamp box, illuminated message plate and calligraphy and painting frame etc. generally do not have suitable ultrathin large tracts of land brightening illumination backlight source because of thickness is little, information faces is used the positive shot-light light projector of installing more, do the backlight direct irradiation if adopt common LED, can't avoid on picture, forming luminous point one by one again because of irradiation distance is too small, make effect not good enough, and effects of energy conservation and environmental protection is good, the ultra thin LED backlight technical products of long service life, because manufacturing process is complicated and cost an arm and a leg, now only be applied in miniature and specialty products occasion miniature dimensions, do not relate to large-scale brightening lighting field backlight as yet.
Summary of the invention
The objective of the invention is to for adapting to the needs of low-carbon economy development situation, provide a kind of LED diffuse reflection backlight: the plastic, transparent plate base that has the design of certain angle polygonal pyramid volume matrix formula, the LED lamp is installed on each inclined-plane of polygonal pyramid body, the conductor lines film that orderly connection transparent panel base presets is switched on and is carried out the science combination with diffuse-reflective material, can obtain the high-quality area source backlight of ultrathin large tracts of land brightening illumination, both expand the led light source application, had advantages of energy saving and environmental protection again.
The technical solution adopted in the present invention is as follows: the plastic, transparent plate base that has the design of certain angle polygonal pyramid volume matrix formula that adopts Shooting Technique processing, the spacing of polygonal pyramid body can be determined according to different needs, the LED lamp is installed in is arranged into matrix on each inclined-plane of polygonal pyramid body to increase the light irradiation distance, the conductor lines film built-up circuit that LED lamp array and transparent panel base preset is also connected power supply, make LED light from all angles directive diffuse reflector to obtain best diffuse effect.
In the such scheme, matrix transparent panel base LED lamp light-emitting area is oppositely installed, the diffuse reflection reflector with homalographic is installed in the i.e. front of advertising lamp box, information board and calligraphy and painting frame etc. dorsad in its light-emitting area a distance, the diffuse reflection of LED lamp spot light is made it to form uniform area light source.
In order to obtain purer area source from fronts such as advertising lamp box, illuminated message plate and calligraphy and painting frames, utilize the transparent panel base of LED to form primary scattering, and do not have LED lamp face one determining deviation place arranged parallel scattering material plate as the light source panel front with the transparent panel base, form scattering for the second time.
In the such scheme, can be as required, luminous with various solid colors, colour mixture or seven color changes, polygonal pyramid body dot spacing and plate basal plane are long-pending can be by being spliced into arbitrary dimension, connect for cutting with scissors button and being aided with hold-down screw between the LED lamp matrix transparent panel base, to satisfy the demand of large-scale backlight.
The present invention passes through such scheme, make the structure of a whole set of backlight very scientific and reasonable, on overall plan with LED matrix polygonal pyramid body transparent panel base and diffuse reflection, scattering material makes up, energising rear drive LED, obtain high-quality large tracts of land thin-type LED area source, reach information issue or the instructions for uses of high-grade calligraphy and painting frame decoration backlight such as lamp box and illuminated message plate, it is low that a whole set of products has power consumption, heat is little, technology is simple and cheap, splice convenient, flexible, luminous characteristics such as evenly, because power consumption is extremely low, can also select solar powered, to produce bigger economic results in society, filled up the blank of current large tracts of land thin-type LED high-quality backlight market application product, good market prospects have been arranged.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 connects the combination schematic diagram for each parts of the present invention.
Fig. 2 is a LED matrix polygonal pyramid body transparent panel base profile schematic diagram of the present invention.
Among the figure: 1, light source panel, 2, the polygonal pyramid body, 3, matrix structure polygonal pyramid body transparent panel base, 4, the LED lamp, 5, the diffuse reflection reflector, 6, the light source backboard.7, LED lamp pin, 8, the conductor lines film that presets of transparent panel base, 9, power supply, 10, the plate base connects the hinge button.
Shown in Fig. 1 embodiment: on each face of polygonal pyramid body 2 on the matrix structure transparent panel base 3, arrange LED lamp 4, constitute light emitting array, conductor lines film 8 built-up circuits that the pin 7 of LED lamp 4 and transparent panel base preset on the polygonal pyramid body 2, be connected with power supply 9 again, make all LED lamp 4 energising backs form light-emitting area, it keeps at a certain distance away towards the diffuse reflection reflector 5 that invests light source backboard 6, the diffuse light transmission forms uniform surface light source by the light source panel 1 of matrix structure transparent panel base 3 and scattering material.
Shown in Figure 2: equally distributed polygonal pyramid body 2 each faces are installed LED lamp 4 formation light emitting arrays on matrix structure polygonal pyramid body transparent panel base 3, and a plurality of matrix structure polygonal pyramid body transparent panel bases 3 connect hinge button 10 with the plate base and are spliced into arbitrary dimension.
Form luminous uniform area source by described LED lamp 4 and diffuse reflection reflector 5, light source panel 1 through matrix structure transparent panel base 3 and scattering material obtains rescattering again, so that brightening advertisement and even, the clear and colorful graph text informations of high-grade calligraphy and painting frame information products display brightness such as thin-type lamp box, illuminated message plate have the advantage of energy-saving and emission-reduction and slimming.
