Abstract
The utility model discloses a light-emitting diode (LED) light source substrate of rectangular stagger distribution type, which comprises a substrate body. A plurality of LED beads are disposed on the substrate body and distributed on the substrate body in a rectangular structure, and the LED beads are distributed on each side of the rectangle. An additional LED unit parallel to long sides of the rectangle is disposed in the rectangular structure and formed by arranging a plurality of additional LED beads, and the additional LED beads and two adjacent LED beads on the long sides of the rectangular structure are arranged alternately. The LED light source substrate of the rectangular stagger distribution type is capable of forming a rectangular luminous structure with good light equalizing effect. Meanwhile, due to the fact that an LED is used as a light source, the LED light source substrate of the rectangular stagger distribution type has the advantages of being not only small in size, low in power consumption but also long in service life and the like and thus has broad application prospects.
Description
Technical field
The utility model relates to lighting technical field, particularly relates to a kind of rectangle formula led light source substrate that is interspersed.
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 good, the low in energy consumption and rectangle that volume is little of a kind of equal light effect formula led light source substrate that is interspersed.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
A kind of rectangle formula led light source substrate that is interspersed; 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, is provided with the additional LED unit parallel with the long rectangular edges of rectangular configuration in the said rectangular configuration; Said additional LED unit is arranged by many additional LED lamp pearls and is constituted, and adjacent two LED lamp pearls are arranged alternately on the long rectangular edges of additional LED lamp pearl and rectangular configuration.
As the further improvement to such scheme, additional LED lamp pearl is arranged on the symmetry axis of adjacent two LED lamp pearls on the long rectangular edges of rectangular configuration.
Further, two LED lamp pearl spacings are 4.58mm on the long rectangular edges of said rectangular configuration, and two LED lamp pearl spacings are 4.68mm on the short rectangular edges.
In addition, the vertical range of LED lamp pearl is 1mm on the long rectangular edges of said additional LED lamp pearl and rectangular configuration.
The beneficial effect of the utility model is: the utility model is as a kind of rectangle formula led light source substrate that is interspersed, because LED lamp pearl is arranged in a rectangular configuration on substrate body, and also is provided with the additional LED unit parallel with the long rectangular edges of rectangular configuration in the said rectangular configuration; Can form the good rectangle ray structure of an equal light effect; The utility model is positive equal mating plate and lens are installed after, can constitute a complete luminescent system, can further increase equal light effect; 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.
The specific embodiment
With reference to Fig. 1, a kind of rectangle formula led light source substrate that is interspersed 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 LED lamp pearl 2 is distributed on each bar rectangular edges of rectangular configuration; Be provided with the additional LED unit 3 parallel with the long rectangular edges of rectangular configuration in the rectangular configuration, additional LED unit 3 is arranged by many additional LED lamp pearls 31 and is constituted, and adjacent two LED lamp pearls 2 are arranged alternately on the long rectangular edges of additional LED lamp pearl 31 and rectangular configuration; Said additional LED lamp pearl 31 is arranged on the symmetry axis of adjacent two LED lamp pearls 2 on the long rectangular edges of rectangular configuration; Two LED lamp pearls, 2 spacings are 4.58mm on the long rectangular edges of rectangular configuration, and two LED lamp pearls, 2 spacings are 4.68mm on the short rectangular edges, and the vertical range of LED lamp pearl 2 is 1mm on the long rectangular edges of additional LED lamp pearl 31 and rectangular configuration; 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.
