Reflecting plate

Abstract

The invention discloses a reflecting plate, which is provided with a base, a protective film and a plurality of directional reflecting-scattering layers. Each directional reflecting-scattering layer is composed of a dispersoid, namely at least one of fluorescent powder, metallic oxide, barium sulfate and barium carbonate. The directional reflecting-scattering layers have high reflective index and the function of directional reflection, and further have the effect of fluorescence enhancement and the function of light scattering. When the reflecting plate is irradiated with a light source, the light is directionally reflected by the directional reflecting-scattering layers and is also subjected to fluorescence enhancement and scattering. The light is cast to an object to be irradiated in the form of diffuse reflection so as to achieve even lighting. The shape of the reflecting plate is not especially limited, and the reflecting plate can be made into reflectors or flat plates in various shapes as required, so that the problems of dazzling, non-uniform brightness, infrared radiation and the like are solved, the brightness is improved, the effective utilization rate of light sources is increased greatly, and energy conservation is achieved.

Description

technical field [0001] The invention relates to a photoelectric material, in particular to a reflection plate suitable for various lighting lamps and displays. Background technique [0002] The reflector of lamps and lanterns for general lighting is used in conjunction with the lamp, and its purpose is to improve the utilization rate of the light emitted by the lamp. In the absence of a reflector, the light of the lamp diverges around the lamp at a 360-degree angle, of which only about 120 degrees (about one-third) directly irradiated to the working or living surface to be used, and most of the light scattered to other places is wasted; in order to improve the light utilization rate of the lamp, generally a reflector or reflector is added to the lamp Reflectors; the main methods are diffuse illumination reflectors using the principle of diffuse reflection and directional illumination reflectors using specular reflection. Directional lighting reflectors mainly include direct...

AI Technical Summary

Problems solved by technology

Directional lighting reflectors mainly include directional light-emitting panels made of PVC lattice reflectors, electroplating, mirror aluminum and other materials. Although the reflectivity of this technology can be as high as 98%, and the brightness can even be increased by more than 60%, the entire lamp The light utilization rate is only about 60%-70%, and there is still a lot of light that has not been utilized.

Moreover, the result of its directional reflection will bring a series of shortcomings that affect people's vision, such as uneven illumination and glare.

However, the scattering material coating based on diffuse reflection, surface micro-engraving, and micro-foaming reflective diffuse lighting reflectors can solve the problems of glare and uneven brightness of lamp lighting, but this is at the expense of lighting utilization.
