Abstract
The utility model discloses a rectangular border distributed LED (light-emitting diode) light source substrate which comprises a substrate body, wherein a plurality of LED lamp beads are arranged on the substrate body, the LED lamp beads are arranged into a rectangular structure on the substrate body and are distributed on all rectangular edges of the rectangular structure respectively. For the LED light source substrate, since the LED lamp beads are arranged into the rectangular structure on the substrate body and each LED is in a rectangular shape, the LED lamp beads are arranged in the way that the long edges of LED lamp beads are parallel with a line direction determined by the rectangular edge on which the LED lamp beads are placed, and the LED lamp beads also are arranged in the way that the short edges of the LED lamp beads are parallel with a line direction determined by the rectangular edge on which the LED lamp beads are placed and a light equalizing chip and a lens are installed on the front side of the LED light source substrate, and thus a complete light emitting system is formed and the light equalizing effect can be reached; meanwhile, as the LEDs are used as light sources, the LED light source substrate provided by the utility model has the advantages of small size, low power consumption, long service life and the like, thus having good application prospect.
Description
Technical field
The utility model relates to lighting technical field, particularly relates to a kind of rectangular shaped rim distribution type LED light source substrate.
Background technology
At present, still traditional xenon source that the light source of projector equipment or some special demonstration product mainly utilizes, the limited service life of xenon source; Generally can only keep hundreds of individual hour or about 1,000 hours; Light source almost just needs about 2 years to change, and the light source of influence, especially projector equipment that secondly also receives weather and external environment condition easily is all the more so; Along with the continuous development of LED technology and perfect; Also have some projector equipments to use LED as light source at present, but the design of led light source still is the basic structure that employing is arranged in proper order or is arranged in parallel basically in the existing projector equipment, all light effect is good inadequately.
Because the problem and the defective of above-mentioned existence are necessary the light source of existing projector equipment or special display device is proposed new improvement.
The utility model content
To the problems referred to above, the utility model provides the rectangular shaped rim distribution type LED that a kind of equal light effect is good, low in energy consumption and volume is little light source substrate.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
A kind of rectangular shaped rim distribution type LED light source substrate; Comprise substrate body; Said substrate body is provided with plurality of LEDs lamp pearl, it is characterized in that: said LED lamp pearl is arranged in a rectangular configuration on substrate body, and said LED lamp pearl is distributed on each bar rectangular edges of rectangular configuration.
As the further improvement to such scheme, said LED lamp pearl is a rectangular shape, and said LED lamp pearl is arranged according to its long limit and the mode that rectangular edges determined line orientations in place parallels.
In addition, said LED lamp pearl is a rectangular shape, and said LED lamp pearl is arranged according to its minor face and the mode that rectangular edges determined line orientations in place parallels.
The beneficial effect of the utility model is: the utility model is as a kind of rectangular shaped rim distribution type LED light source substrate; Because LED lamp pearl is arranged in a rectangular configuration on substrate body; And LED is originally as rectangular shape, and the mode that the mode that mode is arranged and LED lamp pearl parallels according to its minor face and each limit of said rectangular configuration that therefore can take LED lamp pearl to parallel according to its long limit and each limit of said rectangular configuration is arranged is behind positive equal mating plate of installation of the utility model and lens; Can constitute a complete luminescent system; Can reach all effects of light, simultaneously, owing to adopt LED as light source; The utility model not only volume is little, low in energy consumption but also have advantage such as long service life, therefore possesses good prospects for application.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the utility model overall structure sketch map one;
Fig. 2 is the utility model overall structure sketch map two.
The specific embodiment
See figures.1.and.2, a kind of rectangular shaped rim distribution type LED light source substrate comprises substrate body 1; Substrate body 1 is provided with plurality of LEDs lamp pearl 2, and LED lamp pearl 2 is arranged in a rectangular configuration on substrate body 1, and said LED lamp pearl 2 is distributed on each bar rectangular edges of rectangular configuration; Because LED lamp pearl 2 is a rectangular shape, LED lamp pearl can be arranged according to its long limit and the mode that rectangular edges determined line orientations in place parallels, or LED lamp pearl is arranged according to its minor face and the mode that rectangular edges determined line orientations in place parallels; The light-source system basic structure of the utility model is; On this encapsulated LED light source, be equipped with even mating plate of high reflective, high light transmission film and optical thin film lens, also can directly adopt the high light transmittance lens of optical design to realize the optical effect of light source, this kind design can reduce the size of light source greatly; Improve the uniformity of light source; Reduce the power consumption of light source,, can improve light source quality and light efficiency effectively simultaneously through optical design and toning.
More than the preferable enforcement of the utility model is specified; Certainly; The utility model can also adopt the form different with above-mentioned embodiment; These do not constitute any restriction to this embodiment, and those of ordinary skill in the art should belong in the protection domain of the utility model conversion of under the prerequisite of the utility model spirit, being done that is equal to or corresponding the change.
