Specific embodiment

In order to make those skilled in the art more fully understand the technical solution in the utility model, below in conjunction with this reality With the attached drawing in new embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that The described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on the utility model In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts The range of the utility model protection all should belong in example.

The utility model embodiment provides a kind of optical device, including for the ontology by light, in the body interior Be provided with the channel that the other end is extended to from described ontology one end, the outlet in the channel prevent take up the ontology plane of illumination or Person's light-emitting surface.It the channel can be from the light transmission medium of the bulk absorption heat for flowing into.

The ontology is used for through light, it has specific shape or with the production of specific material, for realizing guidance Light propagation realizes light modulation effect.

By flowing into the channel of body interior and can carry over channel from the light transmission medium of bulk absorption heat in medium and flow During medium simultaneously from bulk absorption heat, so that the heat generated in optical device be taken out of, realize to optical device Heat spreading function, preferable heat dissipation effect can be reached, the medium light transmission flowed in channel passes through light so that not influencing light Learn device.Therefore compared with prior art, the present embodiment optical device can reach preferable heat dissipation effect, and not influence light It propagates.

With reference to embodiment and this optical device is described in detail in attached drawing.

A kind of optical device provided in this embodiment includes ontology, and the ontology is for passing through light.

The channel that the other end is extended to from ontology one end is provided in body interior, channel can be from bulk absorption for flowing into The light transmission medium of heat, channel, which extends to the other end from ontology one end, keeps the medium of flowing larger by the range of ontology, can Effectively absorb the intrinsic heat of optical device.The outlet in channel prevents take up the plane of illumination or light-emitting surface of ontology, keeps away in this way Exempt to influence the light propagation by optical device.
