Description
Technical field
The utility model relates to a kind of LED lighting device.
Background technology
Occur at present the product that LED combines LGP to be used to throw light on the market, be about to incidence surface one side of the LGP of LED module setting.This illuminating product sends soft light and receives liking of a lot of users.
In the said goods, spill from the side of LGP, can increase reflex reflector in the side of LGP usually,, improve light efficiency to utilize luminous energy as much as possible in order not make light.This structure causes the volume of light fixture to become big, and cost increases.
The utility model content
The utility model technical problem to be solved is: a kind of LED lighting device that improves the edge light leak is provided, and it is simple in structure that this lighting device is compared prior art, and can improve the utilization rate of light well.
In order to solve above-mentioned technical problem, the utility model proposes a kind of LED lighting device that improves the edge light leak, comprises LED module and LGP, and the LED module comprises the LED lamp on PCB and the PCB; To edge LED lamp should be arranged, this edge LED lamp is asymmetric LED lamp at said LGP edge, and the LED on this asymmetric LED lamp is arranged on the eccentric position of lens, and the dioptric direction of non-sym lens is in LGP.
Preferably: the lens of said asymmetric LED lamp are peanut shape, and the LED of asymmetric LED lamp is provided with the minor axis eccentric position of shelled peanut.One Chinese patent application number discloses a kind of non-sym lens of shelled peanut shape for the patent application of 200910115467.X, and the lens of asymmetric here LED lamp of the present invention can be the structures of these lens.
Preferably: be equipped with said asymmetric LED lamp in the edge of said LGP.
Preferably: said asymmetric LED lamp embeds in the incidence surface of said LGP.
Preferably: said asymmetric LED lamp is arranged on a side of said LGP incidence surface.
Preferably: exiting surface one side at said LGP is provided with the transparent panel that is used to protect LGP.
Preferably: said transparent protection plate is glass or resin.
Preferably: said transparent strip is monochromatic or colored.Monochrome can be various monochromes such as red, green, grey, Huang, and colour can be the combination of several kinds of color block.
The beneficial effect of the utility model:
Compare prior art, the LED lamp that the utility model will be located at the LGP edge changes asymmetric LED lamp into, and the dioptric direction that makes lamp is towards the inboard center of LGP.Such structure can make the few as much as possible edge from LGP of the light of LED lamp spill; And concentrate in the directive LGP; Can improve the light utilization efficiency of the LED lamp that is in the LGP edge significantly; This is for LED lamp negligible amounts, with the desk lamp that edge LED lamp is the main body, and light utilization efficiency is especially obvious.This structure can not need to be located in the prior art reflex reflector of LGP side, and therefore, the volume of light fixture can design forr a short time, and its structure is also simpler, has reduced parts and has also reduced cost.The utility model also can be used for the LED-backlit field.
