Abstract

The utility model provides an LED lamp backlight. LED lamps are arranged on inclined faces of arrayed polygonal pyramids in a transparent substrate and connected with a wire film preset on the transparent substrate, and after power is on, the LED lamps emit light from all angles to a diffuse reflection board to achieve the diffuse reflection effect. A luminous faces of the LED lamps on the transparent substrate are opposite to the front face of a light box, a diffuse reflection reflector having an area the same as that of the diffuse reflection board is mounted at a position on the luminous face of the transparent substrate by a certain distance, point-source of light of the LED lamps is reflected into area-source of light by means of diffuse reflection by the aid of the diffuse reflection reflector, then area-source of light is scattered secondarily by the transparent substrate and a scattering panel mounted parallel thereto, and the light source is evener. The light can be in single colors, mixed colors or variable seven colors, and spaces among the polygonal pyramids and area of the substrate are adjustable flexibly. The backlight is applicable to various backlight fields, is energy-saving and environment-friendly, has the advantages of simple process, low cost and the like, fills the gap of application products medium and large sized thin LED backlights, can be used for light boxes, information boards, frames of calligraphy and painting and the like, and is excellent in market prospect.

Description

Polygonal pyramid body LED diffuse reflection backlight

Technical field

The utility model relates to a kind of backlight assembly of usefulness of large tracts of land brightening illumination, is exactly a kind of ultra thin LED lamp brightening background light source particularly.

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 purpose of this utility model is to adapting to the needs of low-carbon economy development situation, provide a kind of LED diffuse reflection backlight: the polygonal pyramid volume matrix matrix structure transparent panel base that has certain angle, 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 scheme that the utility model adopted is as follows: adopt the matrix structure polygonal pyramid body transparent panel base that has certain angle, 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 matrix structure polygonal pyramid body 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 structure polygonal pyramid body transparent panel base LED lamp light-emitting area is oppositely installed, the i.e. front of advertising lamp box, information board and calligraphy and painting frame etc. dorsad, at the diffuse reflection reflector of its light-emitting area a distance installation, the diffuse reflection of LED lamp spot light is made it to form uniform area light source with homalographic.

In order to obtain purer area source from fronts such as advertising lamp box, illuminated message plate and calligraphy and painting frames, utilize the matrix structure polygonal pyramid body 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 thereof 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 utility model 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.
