Background technology
LED planar lamp is that LED point light source is converted to the light fixture of planar light source, energy-saving and environmental protection that its feature has except LED, efficiently and except the long-life, also there is " seeing that light loses lamp " that planar light source has, light-emitting area is big, light is soft, the feature such as not dazzling.It is particularly well-suited to the occasions such as office, school, library, family, hospital, is of value to the long-time sight protectio of working and learning person under light, is increasingly subject to the favor of people.LED planar lamp is usually by LED backlight principle, is divided in form " directly-down light source type " and " side-light type light source type " two kinds.At present from weight, the aspect requirement such as easy for installation and attractive in appearance, wish that LED planar lamp can realize ultrathin, but for " directly-down light source type " flat lamp, because its light source needs bigger diffusion length, so cannot slimming, general thickness is all at more than 25mm；And " side-light type light source type " flat lamp, owing to the general thickness of its light fixture is decided by the thickness of backing thickness and light guide plate, support its bad mechanical strength too thin, and the flatness of support is difficult to ensure that；And if light guide plate is too thin, its flatness requirement is significantly high, if flatness is poor, the light that then LED sends is revealed from the tangential direction of plane, the light extraction efficiency making flat lamp is relatively low, so " ultrathin " of " side-light type light source type " flat lamp is decided by the flatness of support and light guide plate, therefore ultra-thin LED lamp structure of the prior art needs to be improved further.
Utility model content
This utility model provides a kind of ultra thin LED flat lamp easy to use for above-mentioned the deficiencies in the prior art.
This utility model is the technical scheme that solution the problems referred to above adopt:
This utility model provides a kind of ultra thin LED flat lamp, including support, reflectance coating, light guide plate, light source fixing part, LED light source and diffusion barrier, described reflectance coating, light guide plate, light source fixing part, LED light source and diffusion barrier are placed in described internal stent, described support is suppressed with reinforcement, described reflectance coating is positioned over described frame bottom, described LED light source is welded on described light source fixing part and forms light source assembly, described light source assembly is placed in the one or both sides of described light guide plate, described light source assembly and described light guide plate are positioned on described reflectance coating, described diffusion barrier is placed on described light guide plate.
Further, described light source fixing part is pcb board, and such as aluminium base, printed circuit board (PCB) or flexible PCB, described pcb board is connected with described LED light source by covering copper wire.
Further, described support is metal rack, and described support is formed by foil compacting, or is formed by die cast metal, and foil thickness used by described support is 0.1～1mm.
Further, described reinforcement is arranged as required to into difformity.
Further, described light guide plate is substrate by refractive index and the akin acrylic board of air.
Further, described LED light source is made up of at least 1 LEDs chip or paster.
The beneficial effects of the utility model are in that:
This utility model provides a kind of ultra thin LED flat lamp, this ultra thin LED flat lamp efficiently solves the contradiction between the material thickness of support and mechanical strength, its flatness is made to reach the requirement of design, simultaneously by the embedding of light guide plate, also ensure that the flatness of light guide plate, it is achieved thereby that LED planar lamp superthin structure and the unification of light extraction efficiency, bring a kind of brand-new use to user and enjoy.

Detailed description of the invention
Specifically illustrate embodiment of the present utility model below in conjunction with accompanying drawing, accompanying drawing is only for reference and illustrates to use, and does not constitute the restriction to this utility model scope of patent protection.
nullAs shown in Figure 1 to Figure 3，This utility model provides a kind of ultra thin LED flat lamp，Including support 1、Reflectance coating 2、Light guide plate 3、Light source fixing part 4、LED light source 5 and diffusion barrier 6，Described reflectance coating 2、Light guide plate 3、Light source fixing part 4、It is internal that LED light source 5 and diffusion barrier 6 are placed in described support 1，Described support 1 is suppressed with reinforcement 11，Described reflectance coating 2 is positioned over bottom described support 1，Described LED light source 5 is welded on described light source fixing part 4 and forms light source assembly，Described light source assembly is placed in the one or both sides of described light guide plate 3，Light source assembly is placed in the both sides of light guide plate 3 in the present embodiment，Uniform light is sent to the exiting surface of flat lamp by the refraction site on light guide plate 3，Described light source assembly and described light guide plate 3 are positioned on described reflectance coating 2，Described diffusion barrier 6 is placed on described light guide plate 3，The point source that LED light source 5 sends converts the light of area source to through light guide plate 3，Exiting surface above light fixture is reflexed to the leakage light in base plate direction，Thus improving the light extraction efficiency of LED planar lamp.
