Abstract
LED LGP, is mainly comprised of sheet material, and plate surface has some light guiding points, and the side opening of sheet material has for placing the groove of LED lamp bar.LED LGP of the present utility model by LGP groove at side surface, make LED lamp bar more multiple beam enter LGP, owing to entering the light beam of LGP, increase, the light of its derivation also increases, thereby the brightness of LED panel light is increased, light efficiency gets a promotion.
Description
Technical field
The utility model relates to field of illumination lamp technology, is specifically related to a kind of LED LGP.
Background technology
At present the light efficiency of LED panel light is 50-60lm/W, and to compare light efficiency lower with other light fixtures, and LED fluorescent tube light efficiency is generally at 80-100lm/W, LED Down lamp light efficiency is generally at 80-90lm/W, because LED panel light light efficiency is lower, cause whole lamp brightness lower, thereby cause irradiated area to reduce.
Figure mono-is existing LED LGP, LED lamp bar is placed on to two sides or four sides of LGP, light beam is entered in LGP, the material of LGP is acrylic/PC sheet material of optical grade, then with thering is high reflectivity and the hitech materials of extinction not, acryl plates bottom surface in optical grade stamps light guiding points with UV screen printing technology, the light that utilizes optical grade acryl plates to draw to send from lamp is in the stop on optical grade acryl plates surface, when light is mapped to each light guiding points, reverberation can be toward all angles diffusion, then destroying conditioned reflex penetrates by LGP is positive, by various density, light guiding points not of uniform size, can make LGP uniformly light-emitting.Owing to LED lamp bar being placed on to two sides or four sides of LGP, prior art is that LED lamp bar width is greater than light guide plate, and a part of light can not enter in tabula rasa, causes the loss of some light, thereby causes light efficiency lower.
Utility model content
The utility model provides a kind of LED LGP, the low problem of light efficiency existing to solve prior art.
LED LGP of the present utility model is mainly comprised of sheet material, and plate surface has some light guiding points, and the side opening that solves technical scheme that its technical problem adopts and be sheet material has for placing the groove of LED lamp bar.
Compared with prior art, LED LGP of the present utility model by LGP groove at side surface, make LED lamp bar more multiple beam enter LGP, owing to entering the light beam of LGP, increase, the light of its derivation also increases, thereby the brightness of LED panel light is increased, and light efficiency gets a promotion.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of prior art LED LGP;
Fig. 2 is the structural representation of the utility model LED LGP in specific embodiment 1;
Fig. 3 is the structural representation of the utility model LED LGP in specific embodiment 2.
The specific embodiment
Example 1
As shown in Figure 2, a kind of LED LGP, mainly by sheet material, formed, plate surface has some light guiding points, two side openings in sheet material left and right have for placing the groove 1 of LED lamp bar, during use, LED lamp bar is put into groove 1, thereby make the LED lamp bar light beam overwhelming majority enter LGP, thereby the light extraction efficiency of LED panel light is got a promotion.
Example 2
As shown in Figure 3, a kind of LED LGP, mainly by sheet material, formed, plate surface has some light guiding points, four sides of sheet material all have for placing the groove 1 of LED lamp bar, during use, LED lamp bar is put into groove 1, thereby make the LED lamp bar light beam overwhelming majority enter LGP, thereby the light extraction efficiency of LED panel light is got a promotion.
Claims (1)
1. a LED LGP, is mainly comprised of sheet material, and plate surface has some light guiding points, it is characterized in that the side opening of sheet material has for placing the groove of LED lamp bar.
