Produce the device of illumination effect visually at on-plane surface

Technical field

The utility model relates to and a kind ofly produces the device of illumination effect visually at on-plane surface.

Background technology

Light source can be divided into direct light source and indirect light source haply; By bulb, fluorescent tube ... the light source that waits luminescence component directly to launch light can be considered direct light source.Light with the light of direct light source presents after via conducting subassembly then can be considered indirect light source.Generally speaking, directly the brightness of light source is higher, therefore is used in lighting use usually; Though also have utilization such as LED to come from the decorative use, when large tracts of land is used, need lay a large amount of LED, and brightness be comparatively dazzling as direct sunshine.The brightness of indirect light source is relatively low, but softer, so be used in decoration, indication usually and as purposes such as backlight modules, and can use a small amount of light source to reach the larger area illumination effect.

Conducting subassembly as indirect light source generally includes optical fiber and LGP; Wherein, optical fiber is the form that belongs to the wire conduction, therefore, for the product that must present planar or visual aspects, all is to adopt LGP as the light conducting subassembly.For example, as LCD TV, display ... wait the backlight module of the light source of product, promptly include LGP and light source, for the electronic product that the body thickness requirement approaches, typically use LED as light source, and this light source is located at the side of LGP, first side of LGP then is provided with a reflector plate, second side surface opposite then is provided with the plural blooming piece of being made up of diffusion sheet and prismatic lens etc., and the periphery in those assemblies surrounds with a housing again.The light that light source sent is entered by the side projection of LGP, and part light is reflected by reflector plate, penetrates by diffusion sheet and prismatic lens in regular turn again.

In order to keep the stability of conducting light, aforementioned LGP all is as far as possible near rigidity, that is LGP is a plane, therefore, only can be applied to the purposes that the plane shows, if to be applied to on-plane surface (for example curved surface, wavy surface ... etc.), then must use the LGP of most small sizes to be spliced into to form that should curved surface, thus, not only processing procedure is loaded down with trivial details, cost is very high, and the curved surface fluency that assembly is formed also can't be perfect.

Summary of the invention

The utility model technical issues that need to address have provided and have a kind ofly produced the device of illumination effect visually at on-plane surface, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

Device of the present utility model comprises: one has flexible and flexible LGP; Also comprise: ray cast can be entered at least one light source in this LGP; This light source is laid at least one side of this LGP.

Compared with prior art, the beneficial effects of the utility model are: can be applied to the usefulness of the on-plane surface case surface of any electrical equipment generation as luminous ornament; Also can be applied to the usefulness of the luminous ornament of the cylinder of any building or non-planar surfaces; Even when producing nonplanar face glass, can cooperate the form of this nonplanar face glass to make backlight module in the future.
