Abstract
The utility model discloses a light-emitting diode (LED) light-emitting disc which is mainly formed by a fixed seat, a reflecting plate, a diffusion plate and an LED light source. The reflecting surface of the reflecting plate is arc-shaped, and light emitted by the LED light source first shines to the reflecting surface of the reflecting plate. Because the reflecting surface is arc-shaped, the light emitted by the LED light source can be evenly dissipated according to the law of light reflection, the aim of improving uniformity is achieved, and dazzle is effectively avoided through the diffusion plate. Accordingly, the LED light-emitting disc can emit uniform and soft light. Moreover, the aim of improving uniformity of the light is achieved by adopting the arc-shaped reflecting surface, a light guide plate universally used in the prior art is not adopted, lighting effect loss caused by the light guide plate can be avoided, the light effect is improved by over 25% in comparison with the prior art, and the LED light-emitting disc can be widely applied to the fields of lighting and display and the like.

The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of LED luminosity scale; Comprise holder, reflecting plate, diffuser plate and led light source; The reflecting surface of said reflecting plate is an arc; Said led light source is positioned at before the said reflecting surface and is connected in said holder, and said led light source shine towards said reflecting surface, and said diffuser plate is positioned at said led light source before and be fixed in said holder.The light that led light source sends exposes to the reflecting surface of said reflecting plate earlier, because reflecting surface is an arc, according to the light reflection law; Can the light that led light source sends evenly be dispersed, reach the purpose that improves the uniformity, effectively prevent dazzle through diffuser plate again; Therefore the LED luminosity scale of the utility model can send even and soft light; It will be further appreciated that the utility model is to adopt curved reflecting surface to reach the purpose that improves the light uniformity, the LGP that does not adopt prior art generally to use; Therefore the light efficiency loss that can avoid LGP to cause, and then make the utility model can increase light efficiency more than 25% than prior art.
The utility model for the further technical scheme that solves its technical problem and adopt is:
Said reflecting plate can be the reflector plate of integrally bending camber.Certain said reflecting plate also only reflecting surface be arc, but its back side is plane or other shapes.
The reflecting surface of said reflecting plate is an arc and can smooth surface.The reflecting surface of said reflecting plate also can be whole curved and its surperficially have some concavity structures and convex structure one of at least.
Said holder has an opening and from the said opening accommodation space that sets to the concave, said reflecting plate and said led light source all are positioned at the said accommodation space of said holder, and said diffuser plate is fixed in the opening part of said holder and seals said opening.
Said led light source can be at least one LED lamp bar.
Said holder has bottom surface and sidewall, and the said accommodation space of holder is surrounded by the said bottom surface and the said sidewall of holder, and said LED lamp bar is connected in the side wall inner surface of said holder.
Said LED lamp bar can be to be rotationally connected with said holder and can to rotate the adjustment irradiating angle around tie point.
Said holder can be for square, and promptly the whole LED luminosity scale also is square, and can be used for lighting field and field of display.Certainly the LED luminosity scale of the utility model is not limited to square; Can be circle, triangle, rhombus, irregularly shaped or other every shapes; Can change the shape of the utility model LED luminosity scale through the shape that changes holder, to adapt to different purposes, different occasion or different aesthetic demand.
The beneficial effect of the utility model is: the LED luminosity scale of the utility model mainly is made up of holder, reflecting plate, diffuser plate and led light source, and the reflecting surface of reflecting plate is arc, and the light that led light source sends exposes to the reflecting surface of said reflecting plate earlier; Because reflecting surface is an arc; According to the light reflection law, can the light that led light source sends evenly be dispersed, reach the purpose that improves the uniformity; Effectively prevent dazzle through diffuser plate again; Therefore the LED luminosity scale of the utility model can send even and soft light, it will be further appreciated that, the utility model is to adopt curved reflecting surface to reach the purpose that improves the light uniformity; The LGP that does not adopt prior art generally to use; Therefore the light efficiency loss that can avoid LGP to cause, and then make the utility model can increase light efficiency more than 25% than prior art, can be widely used in fields such as illumination and demonstration.
