Description
Technical Field
The application relates to a lamp, in particular to a light-transmitting plate and a panel lamp.
Background
In the existing planar light-emitting products, the light sources are all point light sources or linear light sources or surface light sources formed by combining the point light sources and the linear light sources, and the areas of the light sources are smaller than the area required to emit light on the plane.
For example, a flat lamp for lighting use, there are three modes, in which a light source is placed at a side of a lamp, passed through a reflecting plate, a light guide plate, a diffusion plate, and then emitted from a plane of the diffusion plate. The structure has the advantages of uniform planar light emission, high cost and multiple materials. The weight is heavy, and the accumulated weight of the various materials is the heaviest of the planar light emitting types. Meanwhile, the light efficiency is very low, the light source emits light to pass through the inside of the light guide plate and then the reflection of the reflecting plate, then passes through the diffusion plate and emits light, so that the light loss is relatively large for a plurality of times, and the light emitting efficiency is greatly reduced.
The second mode is a mode that the light source is directly matched with the diffusion plate, but the structure needs to control the light source to have a large distance from the diffusion plate so as to avoid bright spots and dark spots which are alternately bright and dark on the diffusion plate, and the mode has the advantages of lower cost than side light emission and higher light efficiency than side light emission. The disadvantage is that the light source must be a large distance from the diffuser plate, resulting in a loss of light efficiency, which does not reach a higher light efficiency. And the larger the distance between the light source and the diffusion plate, the larger the bracket between the fixed light source and the diffusion plate, the higher the cost.
The third mode is that the light source is matched with a lens firstly, the lens is adopted to perform the primary diffusion effect, and then the light source passes through the diffusion plate to solve the planar luminous effect. This has the advantage that the distance between the light source and the diffuser plate can be reduced. The disadvantage is that adding lenses reduces the light efficiency and adding lenses increases the cost.
For example, a bottom-lighting lamp box adopts a plurality of LED light sources or lamp tubes, and adopts two modes, wherein the first mode is that the light sources or lamp tubes are quite large in distance from a display board of the lamp box, the display board has the advantages of being uniform in appearance, and the defects of being quite large in size, occupying larger space of a place and increasing potential safety hazards due to the influence of wind power on high altitude. The second mode is that a lens is additionally arranged on the light source, the lens is adopted to perform the primary diffusion effect, and then the primary diffused light rays are projected onto the display board. The advantage is that the volume of the lamp box can be reduced, and the wind power can be reduced. The disadvantage is that adding lenses reduces the light efficiency and adding lenses increases the cost.
For example, there are two modes of backlight sources of a liquid crystal display television, in which a light source is placed at a side of a lamp, and light is emitted from a plane of the diffusion plate through a reflection plate, a light guide plate, a prism plate, a diffusion plate. The advantage of this construction is that the planar light output is relatively uniform. The disadvantage of this construction is the high cost and the need for multiple materials to solve. The weight is heavy, and the accumulated weight of the various materials is the heaviest of the planar light emitting types. Meanwhile, the light efficiency is very low, the light source emits light to pass through the inside of the light guide plate and then the reflection of the reflecting plate, then passes through the prism plate and the diffusion plate and then emits light, so that the light loss is relatively large for a plurality of times, and the light emitting efficiency is greatly reduced.
The second mode is a bottom lighting mode, which adopts a plurality of LED point light sources, a diffusion lens is additionally arranged on each LED light source to perform preliminary diffusion of light, and the light after preliminary diffusion passes through a diffusion plate, so that the backlight source of the television emits light uniformly. The advantage of this approach is that the light efficiency of the backlight is uniform. The disadvantage is that the lens is added and the thickness of the backlight cannot be made thinner. And adding lenses increases cost.
For example, if a bottom lighting mode that the light source is vertical or approximately vertical is adopted in the decorative plane lighting product, the optical effect that a consumer sees the plane through plane lighting is solved by adopting two modes of increasing the distance between the light source and the plane and adding lenses. The cost is increased and the light efficiency is reduced.
