Abstract

The utility model discloses an LED panel lamp which comprises an LED light source, a frame and a light guide plate. The frame is arranged around the periphery of the light guide plate, and the LED light source is arranged between the frame and the light guide plate which comprises a front face and a back face. The LED panel lamp further comprises light reflection paper and a back plate. A light-transmitting hole is formed in the middle portion of the light reflection paper, the light reflection paper is pasted to the back face of the light guide plate, a through hole is formed in the middle portion of the back plate, the back plate abuts against the light reflection paper, and the through hole is vertically aligned with the light-transmitting hole. Due to the fact that the through hole of the back plate is vertically aligned with the light-transmitting hole of the light reflection paper, light can be directly emitted out from the front face of the light guide plate or the back face of the light guide plate, the double-face light emitting effect is achieved, and illumination brightness is increased. Through adjustment of the size of the light-transmitting hole, various design requirements can be met, and light emitting with different proportions of the upper portion and the lower portion is achieved. Lattice points are arranged on the front face and the back face of the light guide plate respectively, so that light is even, a diffusion plate is not needed, and cost is saved.

Description

A kind of LED panel light

Technical field

The utility model relates to a kind of LED panel light.

Background technology

LED panel light is a suitable U.S. high-grade indoor illumination light fitting, not only has good illuminating effect, but also can bring beautiful impression to people, uniform flat luminous effect, illuminance uniformity is good, and light is soft, comfortable, can effectively alleviate kopiopia, obtain liking of numerous consumers.

But, existing LED panel light function singleness, it is maximum that brightness of illumination cannot reach, and for larger space, often need, multiple LED panel lights are set, cause the increase of use cost.

Utility model content

The utility model provides a kind of LED panel light, and it has overcome the existing deficiency of background technology.The utility model solves the technical scheme that its technical problem adopts:

A kind of LED panel light, comprise LED lamp source, frame and LGP, this frame is around the periphery setting of this LGP, and this LED lamp source is between this frame and this LGP, and this LGP has a positive and back side, also comprise reflective sheeting and backboard, the middle part of this reflective sheeting is run through and is provided with loophole, and this reflective sheeting abuts on the back side of this LGP, and the middle part of this backboard is run through and is provided with through hole, this backboard is pressed against on this reflective sheeting, and this through hole vertically aligns with this loophole.

Among one preferred embodiment: be all provided with site on the front and back of this LGP.

The technical program is compared with background technology, and its tool has the following advantages:

1. the loophole of this reflective sheeting and the through hole of this backboard vertically align, and light can directly penetrate from the front of this guide plate, also can penetrate from the back side of this LGP, reaches the effect of double-side, thereby increases the bright brightness of issuing permit.

2. by the size of this loophole of configuration, can meet various designing requirements, realize different upper and lower ratio bright dippings.

3. on the front and back of this LGP, be all provided with site, make light comparatively even, without using in addition diffuser plate, can reduce luminous flux loss, save cost.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Fig. 1 has illustrated the perspective exploded view of a kind of LED panel light of the utility model.

Fig. 2 has illustrated the schematic perspective view of a kind of LED panel light shown in Fig. 1.

Fig. 3 has illustrated the cross-sectional schematic along A-A line in Fig. 2 shown in Fig. 1.

Fig. 4 has illustrated the enlarged diagram at B place in Fig. 3.

The specific embodiment

Please refer to Fig. 1 to Fig. 4, a kind of LED panel light of the present utility model, has double-side function, and the intensity difference of double-side.This LED panel light comprises some LED lamps source, a frame 10, a LGP 20, a reflector 30 and a backboard 40.

This LGP 20 has one positive 22 and one back side 24.On the front 22 of this LGP 20 and the back side 24, be all provided with site, described site generates by the mode of printing or laser printing.

The middle part of this reflective sheeting 30 is run through and is provided with a loophole 32.Described loophole 32 passes through for the light that the back side 24 of this LGP 20 is sent.The brightness of light that can be as required, the size that increases or dwindle this loophole 32.

This backboard 40 is for being fixed on this LGP 20 in this frame 10.The middle part of this backboard 40 is run through and is provided with a through hole 42.Shape, the size of this through hole 42 are identical with this loophole 32.

Described LED lamp source is arranged on the medial surface of this frame 10.This LGP 20 is embedded in this frame 10, and this frame 10 is around the periphery setting of this LGP 20, and described LED lamp source is between this frame 10 and this LGP 20.This reflective sheeting 30 abuts on the back side 24 of this LGP 20, covers the peripheral position at the back side 24 of this guide plate 20.This backboard 40 is pressed against on this reflective sheeting 30, and this through hole 42 vertically aligns with this loophole 32.

This guide plate 20 whole positive 22 on have light penetrate.The back side 24 area corresponding with this loophole 32 of this guide plate 20 has light to penetrate.By regulating the size of this loophole 32, can realize the different upper and lower ratio bright dippings of this LED panel light.

The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.

Claims

1. a LED panel light, comprise LED lamp source, frame and LGP, this frame is around the periphery setting of this LGP, and this LED lamp source, between this frame and this LGP, is characterized in that: this LGP has a positive and back side, also comprise reflective sheeting and backboard, the middle part of this reflective sheeting is run through and is provided with loophole, and this reflective sheeting abuts on the back side of this LGP, and the middle part of this backboard is run through and is provided with through hole, this backboard is pressed against on this reflective sheeting, and this through hole vertically aligns with this loophole.

2. a kind of LED panel light according to claim 1, is characterized in that: on the front and back of this LGP, be all provided with site.
