The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
The purpose of the utility model is providing a kind of light source module exactly, in order to before promoting light source module and lighting with light the identity of back.
A kind of light source module is proposed according to the utility model one embodiment, comprise LGP, in order to light source that light to LGP is provided, be arranged on LGP exiting surface on even light film, and be arranged on the colo(u)r filter on the even light film.When the light of light source passes through even light film and colo(u)r filter mixed light, show another color.
Even light film preferably can be the white reflection sheet.The material of even light film can be polyester (polyester; PET).Colo(u)r filter comprises the look photoresist layer of a substrate and complete covered substrate.The look photoresist layer can be monochromatic light resistance layer or chromatic photoresist layer.Light source module can more optionally comprise patterned layer, is formed at even light face on one of colo(u)r filter face, when some bright light source, and the pattern of display pattern layer.Light source module more comprises transparent protection plate, is arranged on the colo(u)r filter.Light source can be arranged on one of LGP side.LGP comprises a plurality of micro-structurals, is formed at exiting surface or bottom surface on the LGP.
Below will clearly demonstrate the spirit of the utility model with graphic and detailed description; Have in the technical field under any common knowledge after the preferred embodiment of understanding the utility model; When can be by the technology of the utility model institute teaching; Change and modification, it does not break away from the spirit and the scope of the utility model.
Light source module regular meeting sets up one deck LGP in bright dipping place, with so that light disperse equably, simultaneously and above LGP, be provided with and have a color diaphragm, for example black optical filter.Therefore, the user sees that the glow color of the light source module of not lighting and lighting is for identical, only has the difference in the brightness.Therefore, the utility model has just proposed a kind of light source module with unique light guide structure, when lighting and not lighting, to have obvious color difference.
With reference to Fig. 1, it illustrates the profile of light source module one embodiment of the utility model.Light source module 100 includes LGP 110, light source 120, even light film 130, colo(u)r filter 140, transparent protection plate 150 and a plurality of transparent double faced adhesive tapes 160.Wherein light source 120 is in order to provide light to LGP 110.Even light film 130 is arranged on the exiting surface 112 of LGP 110, and even light film 130 is fixed on the LGP 110 by transparent double faced adhesive tape 160.Colo(u)r filter 140 repeatedly places on the even light film 130 again, is fixed on the even light film 130 by transparent double faced adhesive tape 160.Transparent protection plate 150 can optionally be arranged on the colo(u)r filter 140, is fixed on the colo(u)r filter 140 by transparent double faced adhesive tape 160, to reach the purpose of the structure of protecting lower floor.
The effect of even light film 130 comprises diffusion light, passes through astigmatic line or mixed light etc.Even light film 130 in the present embodiment can be reflector plate, and the material of even light film 130 can be polyester (polyester; PET).For example, even light film 130 is to present white under general state, when light penetration, can promote the brightness of light, and make the light that is sent be similar to white light.In addition, even light film 130 can be transparent or translucent material.
Colo(u)r filter 140 is arranged on the even light film 130.Colo(u)r filter 140 includes the look photoresist layer 144 of substrate 142 and complete covered substrate 142.This look photoresist layer 144 can be monochromatic light resistance layer and chromatic photoresist layer.For instance, colo(u)r filter 140 can be for having the optical filter of black look resistance.
The size of LGP 110, even light film 130 and colo(u)r filter 140 can be identical or different.This light source module 100 sees through the combination of even light film 130 and colo(u)r filter 140, can be so that light source module 100 shows various colors respectively when light source 120 is lighted and do not lighted.Promptly when light source module 100 when light source 120 is not lighted, user's meeting of seeing of ground floor visually is the color of coloured colo(u)r filter 140, black as previously mentioned.
With reference to Fig. 1 and Fig. 2, when light source 120 was not lighted, even light film 130 was hidden by colo(u)r filter 140 simultaneously, the color that the user is observed visually, i.e. and the color of light source module 100 demonstrations can be the color that colo(u)r filter 140 directly appears.But when light source 120 is lighted,, can make light after through even light film 130 and colo(u)r filter 140 mixed lights, become and be similar to white light, and make light source module 100 show another color that is different from colo(u)r filter 140 by the effect that even light film 130 is produced.
With reference to Fig. 3, it illustrates the profile of light source module 100 another embodiment of the utility model.Light source module 100 more can comprise the patterned layer 170 that is arranged on the even light film 130 except that aforementioned LGP 110, light source 120, even light film 130, colo(u)r filter 140, transparent protection plate 150 and transparent double faced adhesive tape 160.Patterned layer 170 can see through printing or mode such as paste is formed on the even light film 130, especially is positioned at even light film 130 in the face of on the one side of colo(u)r filter 140.Patterned layer 170 can comprise printing ink.
Simultaneously with reference to Fig. 3 and Fig. 4, as previously mentioned, after light source 120 is lighted; The light that LGP 110 sends can show the light that is similar to white light after sparing light film 130 and colo(u)r filter 140 mixed lights; In the present embodiment, have more patterned layer 170 on the even light film 130, therefore; When light source 120 is lighted, the pattern of meeting display pattern layer 170 on light source module 100.
With reference to Fig. 5, it illustrates the profile of the another embodiment of light source module of the utility model.The material of aforementioned even light film 130 is all done explanation with reflector plate, yet even light film 130 can also be diffusion sheet.In order to reach light that light source 120 sends through becoming the effect of another color behind colo(u)r filter 140 and even light film 130 (for the diffusion sheet) mixed light, LGP 110 lower floors more must have reflecting plate 180.
Can know by above-mentioned the utility model preferred embodiment, use and the utlity model has advantage.The light source module of the utility model has special light guide structure, makes light after through even light film and colo(u)r filter, is different from the color that shows colo(u)r filter when not selecting bright light source.So can highlight light source module light before with light after color contrast, promote the identity of light source module.
Though the utility model discloses as above with a preferred embodiment; Right its is not in order to limit the utility model; Anyly have the knack of this skill; In spirit that does not break away from the utility model and scope, when can doing various changes and retouching, so the protection domain of the utility model is when looking being as the criterion that the accompanying Claim protection domain defined.
