Abstract

The utility model discloses a round uniformly-distributed LED (light-emitting diode) light source substrate. The LED light source substrate comprises a substrate body, wherein a plurality of LED lamp beads are arranged on the substrate body; a round area formed by adjacent connection of a plurality of triangles is distributed on the substrate body; and the LED lamp beads are arranged on the vertexes of the triangles, so that a round uniform lighting structure taking the triangles as basic lighting units is formed. According to the round uniformly-distributed LED light source substrate, after a light-equalizing plate and a lens are mounted on the front side, a complete lighting system can be formed, so that the light-equalizing effect can be further enhanced; and meanwhile, an LED is utilized as a light source, so that the LED light source substrate is small in volume and low in power consumption and also has the advantages of long service life and the like, therefore, the LED light source substrate is good in application prospect.

Description

The even distribution type LED light source substrate of a kind of circle

Technical field

The utility model relates to lighting technical field, particularly relates to the even distribution type LED light source substrate of a kind of circle.

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 circular evenly distribution type LED light source substrate that a kind of equal light effect is good, low in energy consumption and volume is little.

The utility model is that the technical scheme that its technical problem of solution is adopted is:

The even distribution type LED light source substrate of a kind of circle; Comprise substrate body; Said substrate body is provided with plurality of LEDs lamp pearl; It is characterized in that: be distributed with the border circular areas that is adjoined each other and arranged and form by a plurality of triangles on the said substrate body, said LED lamp pearl is located on the vertex of a triangle, and forming one is the circular uniformly light-emitting structure of basic luminous units with the triangle.

As the further improvement to such scheme, said triangle is an equilateral triangle.

In addition, the length of side of said equilateral triangle is 5.2mm.

The beneficial effect of the utility model is: the utility model is as the even distribution type LED light source substrate of a kind of circle, and owing to being distributed with the border circular areas that is adjoined each other and arranged and form by a plurality of triangles on the substrate body, the LED lamp is located on the vertex of a triangle by pearl; Forming one is the circular uniformly light-emitting structure of basic luminous units with the triangle; 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, the even distribution type LED light source substrate of a kind of circle comprises substrate body 1; Substrate body 1 is provided with plurality of LEDs lamp pearl 2, is distributed with the border circular areas that is adjoined each other and arranged and form by a plurality of triangles 3 on the substrate body 1, and LED lamp pearl 2 is located on the summit of triangle 3; Forming one is the circular uniformly light-emitting structure of basic luminous units with triangle 3, and said triangle 3 be an equilateral triangle, starts from the consideration of size of LED own and product illumination effect; The length of side of equilateral triangle 3 is set to 5.2mm, and the light-source system basic structure of the utility model is on this encapsulated LED light source, to 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, improves the uniformity of light source, reduces the power consumption of light source; Through optical design and toning, can improve light source quality and light efficiency effectively simultaneously.

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.
