Abstract
This invention relates to an optical channel structure composed of multiple reflecting plates, in which, these plates are not completely the same and laminated to form a hollow pipe and light passes through it.
Description
Technical field
The present invention is about a kind of light channel structure, particularly a kind of light channel structure that is used in optical axis and the uneven projector system of optical channel central shaft.
Background technology
In general optical projection system, need a condenser system usually, with the back outgoing that evenly distributes of the light of incident, use optical channel (light tunnel) at present usually.
And traditional optical channel generally is coated with optical thin film by the inner wall surface of four slides, and superimposed each other by these slides again, its inside surface forms an optical channel, and light just can enter optical channel and produce reflection.As shown in Figure 1, it is the synoptic diagram of traditional optical channel 100, and it is made of the slide 101 that four leaf length equate, these slides are superimposed with each other, and form an optical channel 102, and wherein the both ends of the surface of these slides are all in the same plane.
The shortcoming of traditional optical channel be optical axis must with the optical channel central axes, for the uneven optical channel of optical axis and optical channel center, only have part light to be entered optical channel and reflect, so the luminosity deficiency, effect extreme difference on essence is used.
In addition, because of optical axis must with the optical channel central axes, light just must enter optical channel and carry out outgoing after the homogenising, thus the contraposition between optical axis and optical channel central shaft, must be very accurate, can guarantee just that light is unlikely scatters and disappears.
Summary of the invention
Therefore, for addressing the above problem, the present invention proposes a kind of light channel structure, can in special light path, use,, can reach when optical axis and optical channel central shaft are not parallel by light channel structure of the present invention, by light channel structure of the present invention, light still can effectively enter optical channel, therefore still can homogenized back outgoing via light that optical channel sent, not because of optical axis and the optical channel central shaft is not parallel can't practical application.
Light channel structure of the present invention is made of a plurality of reflector plate, and wherein these reflector plates are superimposed with each other, and forms a hollow pipeline, and this hollow pipeline is optical channel, and at these reflector plate inside surfaces difference plated films, so that light enters and can produce reflection.
The present invention utilize four reflector plates wherein one or more pieces, protrude from other reflector plate, make when the optical axis of projector and optical channel central shaft are not parallel, light still can enter by the reflector plate that protrudes in other reflector plate in the optical channel, and reflect, making still can be homogenized via the light that optical channel sent.The present invention compares with traditional optical channel, can solve when optical axis and optical channel central shaft are not parallel the shortcoming that traditional optical channel can't effectively be used; The present invention still can make light inject the back outgoing when optical axis and optical channel central shaft are not parallel.
In addition, that the shape of these reflector plates can be is trapezoidal, rectangle, rule or irregular polygon, and the material of these reflector plates is a glass.
And light channel structure proposed by the invention not only can be used for the optical projection system of optical axis and optical channel central axes, more can be used for optical axis and the uneven optical projection system of optical channel central shaft, is a multi-functional optical channel.
In addition, light channel structure proposed by the invention, optical axis and optical channel central shaft needn't can guarantee that the light quantity of injecting with outgoing is certain through contraposition accurately.The present invention is compared to traditional optical channel, and not only fineness is lower, and can be suitable for multiple situation.
For above and other objects of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
