Abstract

The utility model discloses a light-emitting diode (LED) side light-emitting flat plate lamp which comprises a light guide plate and LED light bars. Four corners of the light guide plate are provided with light inlet surfaces, the LED light bars comprise high-power LED lamps, and the light bars are arranged at the positions of the light inlet surfaces of the four corners of the light guide plate. According to the LED side light-emitting flat plate lamp in the technical scheme, due to the fact that the high-power LED lamps are adopted, the four corners of the light guide plate are provided with the light inlet surfaces correspondingly, the number of used LED lamp beads is reduced, the number of used aluminum substrates is reduced, and accordingly the cost is reduced. The light inlet surfaces are small, rays are reduced, and the LED side light-emitting flat plate lamp is favorable for reducing bright sides and glare and improving light outlet uniformity.

Description

A kind of LED side light emitting plane lamp

Technical field

The utility model relates to LED lighting technical field, is specifically related to a kind of LED side light emitting plane lamp.

Background technology

Side light emitting plane lamp as depicted in figs. 1 and 2, generally comprises: LGP 10, LED lamp bar 20, diffuser plate 30 and framework 40.LED lamp bar 20 is arranged on the side of LGP 10, and diffuser plate 30 is stacked with LGP 10, and LGP 10, LED lamp bar 20 and diffuser plate 30 are all fixedly installed in described framework 40.The square frame that framework 40 adopts aluminium section bar to make conventionally.On LED lamp bar 20, be provided with some LED lamps (all adopting low-power LED lamp, as 3014,3528), the light that LED lamp sends penetrates after diffuser plate 30 diffusions from LGP one side after injecting LGP 10, thereby realizes illumination.

At present LED side light emitting plane lamp application is on the market a lot, with regard to it enters light mode, generally has two kinds: the first as depicted in figs. 1 and 2, is that four sides are entered light mode, in four sides of LGP 10, is provided with a LED lamp bar 20.The side light emitting plane lamp of this kind of structure, owing to adopting low-power LED lamp, but also needs four aluminium bases to make LED lamp bar 20, causes LED lamp pearl, aluminium base large usage quantity thereby cost higher; And owing to entering, light area is large, ray is many, causes bright border phenomenon and dazzle serious; In addition, low-power LED lamp pearl often quality is unstable, easily affects the quality of LED side light emitting plane lamp.

LED side light emitting plane lamp in up-to-date technology, has adopted structure as shown in Figure 3 and Figure 4, is the structure that two offsides enter light mode.The LED side light emitting plane lamp of this structure is by being the LED lamp pearl (as 5630 lamp pearls) of power in use, LED lamp bar 20 is only set in the two opposite sides of LGP, and another dual-side can adopt reflecting paper that light reflection is utilized, compare LED side active flat panel that four sides enter light mode etc. and there is certain progress, but the consumption of LED lamp pearl and aluminium base is still slightly large, cost needs further to be reduced; And outgoing light homogeneity is on the low side, enter light area still large, ray is more, bright border phenomenon, dazzle are serious; And framework 40 area of dissipations are limited, cause heat radiation bad, therefore still have much room for improvement.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of LED side light emitting plane lamp, further solves the large usage quantity of existing LED side light emitting plane lamp LED lamp pearl and aluminium base, enters that light area is large, bright border, problem that glare phenomenon is serious.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A side light emitting plane lamp, comprising: LGP and LED lamp bar, and four jiaos of described LGPs have into light face, and described LED lamp bar comprises high-powered LED lamp, and described lamp bar is arranged on the Guang Mianchu that enters of four jiaos of LGPs.

In preferred technical scheme, described in to enter light face be plane.

In further preferred technical scheme, described plane becomes miter angle with the side of LGP.

In preferred technical scheme, described in to enter light face be arc surface.

In further preferred technical scheme, two adjacent side of described arc surface and LGP are tangent.

The beneficial effects of the utility model are:

Adopted a kind of LED side light emitting plane lamp of technical solutions of the utility model, owing to having adopted high-power LED lamp, and four jiaos at LGP arrange into light face accordingly, thereby have reduced the usage quantity of LED lamp pearl and the consumption of aluminium base, thereby have saved cost.And this kind of mode to enter light face less, ray reduces, and is conducive to reduce bright border and glare phenomenon, and improves and uniformity of light.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The specific embodiment

Embodiment mono-

A kind of LED side light emitting plane lamp that this specific embodiment provides as shown in Figure 5 and Figure 6, also comprises: LGP 10, LED lamp bar 20, diffuser plate 30 and frame 40.Be with the difference of prior art, four jiaos of described LGP 10 are specially provided with into light face, what on described LED lamp bar 20, adopt is high-power LED lamp (as the above LED lamp of the 1W pearls such as 3030,3535), and described lamp bar 20 relative set are at the Guang Mianchu that enters at LGP 10Si angle.

Adopted a kind of LED side light emitting plane lamp of this specific embodiment technical scheme, owing to having adopted high-power LED lamp, and four jiaos at LGP 10 arrange into light face accordingly, thereby the usage quantity of LED lamp pearl and the consumption of aluminium base have been reduced, because the power of single led lamp is larger, requirement reduces naturally, and then the length of aluminium base is corresponding reduces, thereby has saved material cost.And the LED side light emitting plane lamp of this kind of mode, enter light face accordingly less, cause ray in LGP 10 to reduce, be conducive to reduce bright border and glare phenomenon, and improve and uniformity of light.

In preferred technical scheme, described in to enter light face be plane.In this specific embodiment, particularly, the light face that enters of described plane becomes miter angle with LGP 10 side.

Embodiment bis-

A kind of LED side light emitting plane lamp that this specific embodiment provides as shown in Figure 7, is with the difference of embodiment mono-, described in to enter light face be arc surface.Particularly, two adjacent side of entering light face and LGP 10 of described circular arc are tangent.

Circular arc is entered light mode and is compared that to enter the lighting angle of light mode large for plane, and coverage is wider, effectively improves the uniformity of surperficial bright dipping.

Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
