Abstract
The utility model provides a light-emitting diode (LED) luminous panel, and relates to an illuminating device. The LED luminous panel is used for realizing a direct type backlight structure on a wedged light guide plate. The LED luminous panel comprises the wedged light guide plate and an LED lamp. The LED lamp comprises an LED chip and a secondary lens on the LED chip. The secondary lens is an asymmetrical batwing lens. A trough is formed on the back surface of the thinnest part of a wedge, and the LED lamp is arranged in the trough. The emergent direction of the batwing lens is deviated to the thick end of the wedge of the light guide plate. The shape of the trough is formed by two integral curved surfaces which are consistent with the emergent surface of the batwing lens. The LED luminous panel has an ingenious structure; and the direct type structure of the wedge light guide plate is realized by utilizing the characteristics of the asymmetrical batwing lens and own shape of the wedge, and many choices are provided for many fields where the application of the wedged light guide plate is required. The LED luminous panel can be used in the fields of illumination and backlight.
Description
Technical field
The utility model relates to a kind of LED lighting device.
Background technology
The LED illumination has replaced traditional incandescent lamp and fluorescent lamp gradually.The LED lamp is a spot light, and its light that sends is concentrated, and can produce dazzling effect.In order to solve the luminous dazzling and dazzling problem of LED, in the prior art, generally adopt light conducting plate structure, promptly adopt the combining structure of the LED and the LGP of straight-down negative or side entering type.
For straight-down negative LED lamp plate, this structure is that led light source is placed the LGP back, and it exists light utilization efficiency to tell somebody what one's real intentions are, and the thicker problem of lamp plate.In order to address this problem; Some improve technology and have adopted the structure of on LGP, establishing groove; As Chinese patent number be 200980107512.5, name is called " lighting device and forming method thereof ", date of publication is the file on February 16th, 2011, it mentions a kind of employing direct-light type LED backlight structure, wherein; Be mentioned to the scheme of on LGP, establishing the groove structure in this document, be used to increase the utilization rate of light.
Chinese patent number discloses a kind of asymmetrical secondary bat wing lens for the patent document that 200910115467.X, name are called " LED lens and LED array structure thereof ".
From present LED-backlit technology, do not have a kind of straight-down negative technology of suitable wedge shape LGP.What the wedge shape LGP all adopted is the side entering type technology.
The utility model content
The utility model technical problem to be solved is: a kind of LED luminous plaque is provided, in order on the wedge shape LGP, to realize the downward back photo structure.
In order to solve above-mentioned technical problem, the utility model proposes a kind of LED luminous plaque, comprises wedge shape LGP and LED lamp, and
Said LED lamp comprises the secondary lens on led chip and the led chip, and secondary lens is asymmetrical bat wing lens;
The back side at the thinnest part of wedge shape is provided with groove, and the LED lamp is located in the groove;
The thick end of wedge shape of the light direction deflection LGP of bat wing lens;
Said groove be shaped as two the disjunctor curved surfaces consistent with bat wing lens light output surface.
Preferably: the LED lamp is located on the substrate, is provided with reflector layer at substrate surface.
Preferably: said substrate is located on the radiator.
Preferably: the LGP both sides in said wedge shape are provided with reflector.
Preferably: be provided with luminescent film at the said LGP back side, the reflective membrane region covered be with substrate on the complementary zone of reflector layer.
Preferably: said reflective membrane is the aluminium film.
The beneficial effect of the utility model:
Compare prior art, the utility model utilizes the uneven characteristics of wedge shape light guide plate, and the place thin at LGP is provided with the LED lamp.Be located at the light that causes at thin place and transmit not enough problem in order to remedy LED, the LED lamp has adopted asymmetric bat wing lens, and on LGP, establishes groove, and this structure makes the light thick zone of wedge shape of fully having led, thereby has realized the effect of even light-guiding.This structure can be utilized the idle space at the thin regional back side of wedge shape LGP, therefore, can not take the space of LGP side, and the device of working it out so can not take bigger space.This structure has been used the characteristics of asymmetric bat wing lens and the characteristics of wedge shape self shape cleverly, has realized wedge shape LGP straight-down negative structure, and for the field that much must use the wedge shape LGP, the utility model provides more choices.The utility model can be used for illumination and backlight all passable.
