Abstract
The present invention relates to the technical field of advertising and label, in particular to an LED area light source, which comprises a transparent or translucent board. Two ends of the transparent or translucent board are respectively provided with a circuit board. The circuit board is provided with a group of LEDs. Light shielding materials are respectively arranged above and under the LEDs. The irradiation light of the LEDs irradiates into the inner of the transparent or translucent board. At least a side of a front side or a back side of the transparent or translucent board is provided with a logo. The logo arranged on the front side of the transparent or translucent board is a light-permeation logo. The present invention solves the technological problems of high price and large energy consumption of the existing fluorescent lamps or energy-saving lamps used for the label and advertising board as the light source, and not only has low cost and energy consumption but also has even and soft light.
Description
Technical field
The present invention relates to advertisement, label technical field, especially a kind of LED area source.
Background technology
Existing label, billboard, as office's board, classroom board, the indication of market shopping district, escape way board, trail guide, rules and regulations and advertising poster etc., there is not light source mostly, be just can see clearly, do not have next these labels of extraneous lamplit situation, Warning Mark and billboard etc. just to perform practically no function at night by natural daylight (sunlight) or extraneous lighting.Have in order to be equipped with light source, have to adopt short fluorescent lamp lamp box of costliness, power consumption, heaviness and life-span; Also paid electricity-saving lamp on probation replaces traditional fluorescent lamp, reaching purpose of energy saving, but the advertising lamp box of this use electricity-saving lamp, power consumption is still quite surprising.For this reason, people attempt the light source as advertising lamp box or label with LED, a kind of " traffic sign group of synchronous flashing " disclosed as Chinese patent CN1388487A, it uses a large amount of LED set of devices battle arrays, and it takes up room greatly, and particularly thickness space is big, in addition, because it is with a large amount of LED set of devices battle arrays, is the combination of spot light, light is not soft also inhomogeneous.
Summary of the invention
The technical problem to be solved in the present invention is: solve existing label and billboard with fluorescent lamp or electricity-saving lamp as light source costs an arm and a leg, energy consumption is big technical problem, the invention provides a kind of LED area source, not only cost is low for it, energy consumption is low, and light is evenly soft.
The technical solution adopted for the present invention to solve the technical problems is: a kind of LED area source, it has transparent or semitransparent plate, transparent or semitransparent plate two ends are respectively arranged with wiring board, one group of LED is housed on the wiring board, the above and below of LED is provided with light screening material, the front or the back side at transparent or semitransparent plate have at least one side to be provided with sign, and the printing opacity that is designated that is arranged on the front of transparent or semitransparent plate identifies.The light that LED sends is injected transparent or semitransparent intralamellar part, forms area source, and light is soft evenly and not dazzling.
When only when the one side of transparent or semitransparent plate is provided with the printing opacity sign, be provided with at the back side of transparent or semitransparent plate and be in the light or reflectorized material, sign is arranged between light-locking material and transparent or semitransparent plate or is arranged on the front of transparent or semitransparent plate.The light that LED sends is injected transparent or semitransparent intralamellar part, forms area source, illuminate be arranged on be in the light or reflectorized material and transparent or semitransparent plate between or be arranged on the sign in the front of transparent or semitransparent plate, light is soft evenly and not dazzling.
For improving the luminosity of LED area source, make light more even soft, described transparent or semitransparent plate adopts poly (methyl methacrylate) plate to make.
For more improving the luminosity of LED area source, on thickness direction, the center line in center line of LED lamp pearl and transparent or semitransparent plate cross section is on same straight line.
The invention has the beneficial effects as follows that LED area source cost of the present invention is low, energy consumption is low, and light is evenly soft.
