On the light-guide plates are disposed light-guide patterns. The two or more light sources connected with the power supply are disposed on the sides of the above several light-guide plates. The light-guide plates made up of Yakeli plates include reflecting plates. The light source is made of LED set.
Description
Technical field
The present invention relates to a kind of area source that is used to throw light on that constitutes by a plurality of LGPs.
Background technology
Also there is not the area source that is used to throw light at present with the LGP formation, what the present invention relates to is the implementation of a kind of innovation of the illuminated area light source that constitutes with LGP, sees also following related application: 1. 2. " area source that is used to throw light on that is made of curved-surface reflection side and LGP " (application number 200610150100.8) 3. " area source that the LGP of band reflection plated film constitutes " (200610140517.6) of " area source that is used for desk lamp/reading lamp " (application number 200610137749.6)
When the LGP area source is the LGP area source of primary source with the LED group especially, when being used for lighting use, the problem of illumination deficiency can appear.This problem because the LGP area source is originally penetrated luminous dispersing and caused, is under the arranging density that allows of the encapsulation diameter at LED on the other hand on the one hand, and the LED group is incident to that the incident intensity deficiency of LGP causes.
The not enough problem of illumination when being used to throw light on for the LGP area source can not improve illumination effectively in the mode that enlarges the LGP area simply, and its volume also is subjected to the restriction as the lighting practicality.
Summary of the invention
At above-mentioned existing LGP area source especially is the deficiency of LGP area source when being used to throw light on of primary source with the LED group, the present invention has adopted a plurality of LGPs to arrange in parallel overlapping, parallel staggered or not parallel staggered mode with innovating, add corresponding reflecting plate, improve the illumination of LED LGP area source in the small product size that can be less effectively.
The present invention is achieved in that a kind of area source that is used to throw light on that is made of a plurality of LGPs, include a plurality of LGPs, a plurality of light source and power supply, wherein, described a plurality of LGP is provided with the leaded light pattern, described a plurality of light source is connected in described power supply, described a plurality of light source is arranged at described a plurality of LGPs side, and by its side incident.Wherein, a plurality of being meant more than 2 or 2.
Wherein, described a plurality of light source is made of a plurality of LED groups.
Wherein, described a plurality of LGPs become parallel overlapping, parallel staggered or not parallel interlaced arrangement, the emission light of described a plurality of LGPs can be overlapped or converge, to improve illuminance.
Wherein, this area source also includes reflecting plate, and reflecting plate is positioned over the back side of described LGP, makes the positive area source that forms than high light of described LGP.Described reflecting plate simultaneously has high reflectance towards LGP, and the shape of reflecting plate is plane, concave surface, U-shaped, arc, cylinder, sphere or prismatic surface, and reflecting plate can be single or multiple, and reflecting plate can be an integral body or is spliced by a plurality of.
The present invention becomes parallel overlapping, parallel staggered or not parallel arrangement with a plurality of LGPs, again with baffle reflection, make its luminous coincidence or converge in LGP just in face of, improved the especially illumination of LED LGP of LGP effectively, make its be more suitable in the illumination purposes.
Description of drawings
Fig. 1 is a decomposition texture schematic diagram of the present invention;
Fig. 2 is a lateral plan embodiment illustrated in fig. 1;
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention.
Fig. 1 is a decomposition texture schematic diagram of the present invention.Shown in the figure is the embodiments of the invention that are staggeredly arranged in parallel by before and after 2 rectangle LGPs, adopts the curved-surface reflection side of curved circular cylinder, and its pattern backlight is a line graph, and each LGP all is one-sided light inlet.
As shown in Figure 1, the present invention includes 11,2 LGPs of 2 LGPs and be provided with 12,2 light sources of leaded light pattern and be made up of LED group 13 and strip pcb board 16, LED organizes the 13 side incident raies from LGP, the curved-surface reflection side 14 of curved circular cylinder and power supply 15.When the present invention worked, LED group 13 made 2 two-sided area sources of the luminous formation of LGP from 2 LGP side incident raies.2 LGPs are reflected to the light of camber reflection surface launching, overlap and converge at the field of illumination outside the LGP front, realize the function of illumination.
2 LGPs 11 can form different shape, and the leaded light pattern can be point-like or wire, and the shape of 2 LGPs can be different with size.LED group 13 can also be carried out half coating makes more light enter LGP from the side.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those skilled in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
