Abstract
The utility model discloses a panel lamp with laterally-arranged light sources. The panel lamp comprises a lamp frame and a light guide module. The two sides of the light guide module are simultaneously provided with LED light source bars. The light guide module is formed by sequentially stacking a light guide plate, a light homogenizing plate, a light scattering plate and a light reflecting plate. The light guide plate, the light homogenizing plate and the light scattering plate are connected and fixed to be a whole. When the light sources on the two sides of the light guide module emit light rays, the light rays are reflected by a light reflecting coating at first, and then the reflected light rays are sequentially scattered by light scattering points on the light scattering plate and further homogenized by homogenizing blind holes in the light homogenizing plate. Thus, the light rays emitted by the light guide plate are quite gentle, visual experience is quite good and the panel lamp with the laterally-arranged light sources is quite suitable for ceiling overhead lamps of chambers or offices with large area.
Description
Technical field
The utility model relates to lighting, relates in particular to a kind of flat lamp for large-scale office space and club.
Background technology
At present, large-scale office or club are used built-in CCFL fluorescent tube as smallpox overhead light fixture.Along with the application of LED light source, large-scale office or club bring into use LED light source as smallpox overhead light fixture.But, use LED light source to have obvious shortcoming as smallpox overhead light fixture: light efficiency is not ideal enough compared with the conventional lamp of equal-wattage, so that Energy Intensity Reduction is not obvious; The hot spot of lamp brightness is obvious, and the uniformity is poor.
Summary of the invention
For solving above-mentioned problems of the prior art, the utility model proposes the flat lamp of the light source side that a kind of luminous efficiency is good, optical fiber is very soft.
The flat lamp of a kind of light source side the utility model proposes, it comprises lamp door and leaded light module, is characterised in that: described leaded light module both sides are provided with LED light source bar simultaneously, and leaded light module is stacked gradually and formed by LGP, even tabula rasa, astigmatism plate, reflector.
One side of described even tabula rasa is provided with the even smooth blind hole of different-diameter different depth.
One side of described astigmatism plate is provided with the scattering points of different-diameter differing heights.
Described scattering points surface is provided with the concentric astigmatic circle of different-diameter.
The medial surface of described reflector is provided with reflecting coating.
Compared with prior art, the utility model arranges even tabula rasa and astigmatism plate at LGP inner face simultaneously.And a side of even tabula rasa is also provided with the even smooth blind hole of different-diameter different depth and be provided with the scattering points of different-diameter differing heights in a side of astigmatism plate.When leaded light module two side light sources are injected light, first pass through the reflection of reflector reflecting coating, through the scattering points in astigmatism plate, reverberation is broken up successively again and even tabula rasa on the further even light of even smooth blind hole, being located at the circle of confusion on scattering points surface further breaks up reflection ray, thereby make the light that irradiated out by LGP very soft, vision is given sympathetic consideration to very good.In addition, by leaded light module both sides, LED light source bar is set simultaneously, at the medial surface of reflector, reflecting coating is set again, this efficiently utilizes the light that LED light source sends, so that obviously reduces energy consumption.Be specially adapted to the smallpox overhead light fixture of large-area office or club.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in detail, wherein:
Fig. 1 is the schematic perspective view of the utility model preferred embodiment;
Fig. 2 is the structural representation of the utility model preferred embodiment;
Fig. 3 is the leaded light module cross-sectional view of the utility model preferred embodiment.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of flat lamp of light source side that the utility model preferred embodiment proposes, it comprises: leaded light module 2 and the lamp door 1 that this leaded light module is connected and fixed, can be flush-mounted in ceiling by lamp door, and as the flat lamp at top.Described leaded light module is provided with LED light source bar 3 in both sides Shang Xia 2 simultaneously, and leaded light module 2 is laminated by LGP 9, even tabula rasa 4, astigmatism plate 6, reflector 8 successively.In this example, as shown in Figure 3, a side of described even tabula rasa 4 is provided with the even smooth blind hole 5 of different-diameter different depth, and this blind hole can be circular hole, elliptical aperture or rectangular opening.One side of described astigmatism plate 6 is provided with the scattering points 7 of different-diameter differing heights, and this scattering points surface is provided with the concentric astigmatic circle 10 of different-diameter.And astigmatic garden circle 10 can be circle projection or lower embedding.The medial surface of described reflector 6 is provided with reflecting coating.Described LGP 9, even tabula rasa 4, astigmatism plate 6 can be made by plastics, acrylic or lucite.
The LED light source bar 3 of leaded light module both sides is injected light, can pass through the reflection of reflector reflecting coating, then through the scattering points in astigmatism plate, reverberation is broken up, and then passes through the further even light of even smooth blind hole on even tabula rasa.Being located at the projection on scattering points surface or the astigmatic circle of lower embedding can further break up reflection ray, again due to light-conductive medias different on the even tabula rasa of light approach (being air in even smooth blind hole), to there is irregular variation in the crevice projection angle of light, thereby make the light that irradiated out by LGP very soft, vision is given sympathetic consideration to very good.In addition, by leaded light module both sides, LED light source bar is set simultaneously, at the medial surface of reflector, reflecting coating is set again, this efficiently utilizes the light that LED light source sends, so that obviously reduces energy consumption.Be specially adapted to the smallpox overhead light fixture of large-area office or club.
Above embodiment is only for illustrating, but not provides constraints.Anyly do not depart from the utility model spirit and category, and equivalent modifications or change that it is carried out all should be contained among the claim scope of rear attached application.
