Abstract
The utility model relates to a kind of LED area light source, comprise acrylic board, 90 ° of knuckle type aluminium heat sinks, two-sided tape, with the LED lamp bar of live wire and SR protective sleeve, shading rubber belt, reflective membrane and filler, a plane of described acrylic board is provided with guide-lighting line and embedded groove, described reflective membrane is close on this plane, the LED lamp bar of described band live wire and SR protective sleeve is installed in embedded groove, short inwall of described 90 ° of knuckle type aluminium heat sinks by two-sided tape and LED lamp bar bonding, long face inwall is pressed on the upside of reflective membrane, short of 90 ° of knuckle type aluminium heat sinks is filled by filler in the space between outer wall and embedded groove, described acrylic board all the other five planes except light source front use shading rubber belt sealing.The beneficial effects of the utility model are: product thickness reduces greatly, and can be made into arbitrary shape, good heat dissipation effect, life of product is high, and the uniformity is high.
Description
Technical field
The present invention relates to a kind of light source, particularly relate to a kind of LED light source, belong to lighting technical field.
Background technology
Generally, the background light source of existing advertising lighting, territory lighting, floor light etc. is all adopt traditional back-lighting and general side luminous lighting, traditional back-lighting directly uses fluorescent tube or LED, after keeping certain height, cover diffuser plate or lamp box panel, and the product of general side luminous lighting has the ultra-fine fluorescent tube of design or LED, fluorescent tube or light bar must rely on or embed in special section bar, again by luminous plaque, diffuser plate or lamp box panel card, be fixed together.
There is following shortcoming in traditional back-lighting: 1. thickness is all thicker, generally at about 80mm; 2. the light of product has dark space, and the life-span is short, and the maintenance frequency increases, costly; 3. waterproof can not be done; 4. uniformity weak effect,
There are the following problems for the back lighting product of general side luminescence: 1. product is thicker, generally at about 10-30mm; 2. profile is single, can not be diversified, because fluorescent tube or LED must ride on section bar, so can only do rectangular dimension, is unfavorable for the processing of various shapes; 3. water proofing property is poor; 4. the uniformity is not enough, generally about 80%.
Utility model content
The present invention is directed to the deficiencies in the prior art, a kind of LED area light source is provided.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A kind of LED area light source, comprise acrylic board, 90 ° of knuckle type aluminium heat sinks, two-sided tape, with the LED lamp bar of live wire and SR protective sleeve, shading rubber belt, reflective membrane and filler, described acrylic board is provided with guide-lighting line and embedded groove, described reflective membrane is close on guide-lighting line, the LED lamp bar of described band live wire and SR protective sleeve is installed in embedded groove, short inwall of described 90 ° of knuckle type aluminium heat sinks by two-sided tape and LED lamp bar bonding, long face inwall is pressed on the upside of reflective membrane, short of 90 ° of knuckle type aluminium heat sinks is filled by filler in the space between outer wall and embedded groove, described acrylic board all the other five planes except light source front use shading rubber belt sealing.
The invention has the beneficial effects as follows:
(1) product thickness reduces greatly, minimumly accomplishes 4-8mm;
(2) arbitrary shape can be made into, without the need to any auxiliary equipment;
(3) by design 90 ° of knuckle type aluminium heat sinks, and paste double faced adhesive tape at this heat sink short inwall, light bar can be made to become to be integrated with heat abstractor, once dispel the heat the heat conduction of LED to short realization of 90 ° of knuckle type aluminium heat sinks by double faced adhesive tape, after the short face of 90 ° of knuckle type aluminium heat sinks is heated, longitudinal heat conduction is given the long face of 90 ° of knuckle type aluminium heat sinks, thus by the heat conduction of inside to outside, thus the heat reducing LED realizes secondary heat radiation, effectively the heat of light bar is taken out of, improve the life-span of product;
(4) different sizes and light bar arrangement, can form the spacing of proportional spacing and gradual change, significantly promote the uniformity, the uniformity can reach more than 90%.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described filler is aluminium flake.
The beneficial effect of above-mentioned further scheme is adopted to be that the more effective heat taken light bar out of and produce, improves the life-span of product.
Further, described guide-lighting line forms through single head engraving machine engraving.
The beneficial effect of above-mentioned further scheme is adopted to be that light bar arrangement can form proportional spacing, improves the uniformity by a larger margin.

Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with example, example, only for explaining the present invention, is not intended to limit scope of the present invention.
A kind of LED area light source, comprise acrylic board 1, 90 ° of knuckle type aluminium heat sinks 2, two-sided tape 3, with the LED lamp bar 4 of live wire and SR protective sleeve, shading rubber belt 5, reflective membrane 6 and aluminium flake filler 7, acrylic board 1 is provided with guide-lighting line 8 and embedded groove 9, described reflective membrane 6 is close on guide-lighting line 8, LED lamp bar 4 with live wire and SR protective sleeve is installed in embedded groove 9, short inwall of 90 ° of knuckle type aluminium heat sinks 2 is bonding by two-sided tape 3 and LED lamp bar 4, long face inwall is pressed on the upside of reflective membrane 6, space between short outer wall of 90 ° of knuckle type aluminium heat sinks 2 and embedded groove 9 is filled by aluminium flake 7, acrylic board 1 all the other five planes except light source front 10 use shading rubber belt 5 to seal.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in invention.
