Description
Technical field
The utility model relates to projection art, particularly relates to a kind of projector.
Background technology
At present, in the optical projection system of projector, the single bulb of many employings is as light source, the light beam that this light source produces is after the process of equal photosystem, be sent on display device, due to the restriction of bulb power and size, projection brightness after adopting single bulb to project is limited, cannot tackle the demand of high display brightness.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of projector, can strengthen logical luminous energy power, improves projection brightness.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of projector, described projector comprises lighting unit and lens unit, described lighting unit comprises orthogonal first white light source of center line and second white light source of emergent light, catoptron and optical wand, the incidence surface of described optical wand is towards described first white light source, and described optical wand is arranged on the output light path of described first white light source, the centerline parallel of the axis of described optical wand and the emergent light of described first white light source, described catoptron is arranged on the output light path of described second white light source, for the incidence surface of the emergent light of described second white light source to described optical wand is reflected, described lens unit comprises coaxial collimating mirror, concave-convex lens, biconcave lens and the biconvex lens be arranged in order of center line along the emergent light of described optical wand.
Preferably, the center line of the axis of described optical wand and the emergent light of described first white light source on the same line.
Preferably, the incidence surface of described optical wand is halved by the side of described catoptron.
Preferably, the incidence surface of described catoptron and described optical wand angle at 45 °.
The beneficial effects of the utility model are: the situation being different from prior art, the center line orthogonal light source of projector of the present utility model by arranging two emergent lights, and the emergent light of two light sources that are coupled by an optical wand, printing opacity is carried out again by concave-convex lens, biconcave lens and biconvex lens, thus logical luminous energy power can be strengthened, improve projection brightness, improve nearly 2 times compared to projection brightness during single light source, obviously can improve projection quality.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment projector.
Embodiment
All features disclosed in this instructions, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this instructions, unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Consulting Fig. 1, is the schematic diagram of the utility model embodiment projector.The projector of the present embodiment comprises lighting unit 1 and lens unit 2.
Lighting unit 1 comprises orthogonal first white light source 11 and the second white light source 12, optical wand 13 and the catoptron 14 of center line of emergent light.The incidence surface of optical wand 13 is towards the first white light source 11, and optical wand 13 is arranged on the output light path of the first white light source 11, the centerline parallel of the axis of optical wand 13 and the emergent light of the first white light source 11, catoptron 14 is arranged on the output light path of the second white light source 12, for being reflected by the incidence surface of the emergent light of the second white light source 12 to optical wand 13.
The lighting unit 1 that the present embodiment provides adopts the orthogonal light source of the center line of two emergent lights, the emergent light of two light sources can be coupled into optical wand, improves brightness of illumination, and then improves projection brightness, through experimental verification, projection brightness can improve nearly 2 times compared to single light source.
Lens unit 2 comprises coaxial collimating mirror 21, concave-convex lens 22, biconcave lens 23 and the biconvex lens 24 be arranged in order of center line along the emergent light of optical wand 13.
The lens unit 2 of the present embodiment adopts polytype lens combination, and light utilization is high, enhances logical luminous energy power, can improve projection brightness further.
In the one application of the present embodiment, the center line of the axis of optical wand 13 and the emergent light of the first white light source 11 on the same line.In the another kind application of the present embodiment, the incidence surface of optical wand 13 is halved by the side of catoptron 14, and the incidence surface angle at 45 ° of catoptron 14 and optical wand 13.The side of catoptron 14 can be resisted against on the incidence surface of optical wand 13, shelters from half incidence surface, makes the emergent light of the first white light source 11 only can be incident on second half of incidence surface.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
