Abstract
The utility model relates to a trapezoid-shaped photoconductive tube component for light gathering, light uniform distribution and shaping of a projector. The trapezoid-shaped photoconductive tube comprises a light guide tube and an iron jacket, wherein the light guide tube is a gradually-tapered trapezoid-shaped tube barrel formed by four quartz glass plates which are distributed on the upper, the lower, the left and the right sides and then adhesively bonded; the diameter of the input port of the tube barrel is larger than that of the output port of the tube barrel; a reflecting film is coated on the inner surface of each quartz glass plate; the iron jacket is an equal-diameter rectangular tube barrel fixedly arranged outside the circumference of the light guide tube and provided with a spring presser. Compared with the prior art, the trapezoid-shaped photoconductive tube component has a good use effect and a low cost and is easy to manufacture, the structural strength of the trapezoid-shaped photoconductive tube component is the same as the most commercially-available adhesive-type rectangular light guide tubes, the reliability can meet the requirements, and the actual trial shows that the cost of the trapezoid-shaped photoconductive tube component is close to that of the adhesive-type rectangular light guide tube and the trapezoid-shaped photoconductive tube component can meet the application requirements for light gathering, light uniform distribution and light type change.
Description
Technical field
The utility model belongs to the optical projection display device technical field, relates to a kind of trapezoidal light pipe assembly that is used for projector's light harvesting, even light, shaping.
Background technology
Known light pipe assembly is by photoconductive tube (Light tunnel) and be fixedly set in the outer rigid structure guard member (being called mail) of photoconductive tube and form, and wherein the shape of photoconductive tube mainly contains rectangle and trapezoidal two kinds.Rectangular light pipes two ends port sizes is identical, and its supporting way adopts two kinds of structures, and a kind of is by some glue fixed form each reflecting optics to be enclosed the measure-alike rectangle socket of two-port, is used in the rigid structure guard member of then it being packed into regulating or protection; Another kind is to add that by support structure the spring pressuring plate of outside mail structure compresses, and does not use a glue mode.Trapezoidal photoconductive tube is the member of the big small-bore inconsistent wedgewise in a kind of two ends, its collection efficiency, even light effect, the shaping shape is better than the rectangular light pipes of using under the equal conditions, the similar rectangular light pipes of its assembling mode, but such structure is because the cutting profile of reflecting optics is a non-rectangle, cause accurate cutting technique to cost an arm and a leg, while is owing to the taper that is shaped as of the mail that is mated, processing technology requires high, cause its price to want expensive several times, therefore also cause the component price of existing market upper trapezoid photoconductive tube and its mail will be much higher than the price of rectangular light pipes assembly than the ordinary rectangular mail.
The utility model content
The purpose of this utility model is to connect the problem that art exists and solve existing, provide a kind of rational in infrastructure, result of use good, cost is low, the trapezoidal light pipe assembly that is used for projector's light harvesting, even light, shaping that is easy to process.
The technical scheme that adopts is so for achieving the above object: the trapezoidal light pipe assembly that is provided comprises photoconductive tube and mail (rigid structure guard member), it is characterized in that: said photoconductive tube is the trapezoidal socket in convergent footpath that forms that distributed by upper and lower, left and right by four quartz glass plates and surround by a glue, the input bore of socket is greater than the output bore, and the inside surface of each quartz glass plate is coated with reflectance coating; Said mail is one and is fixedly set in the isometrical rectangle socket that the outer wall of photoconductive tube has spring pressuring plate.
A kind of concrete technical scheme of the present utility model is: the photoconductive tube in the assembly can be one and be surrounded the trapezoidal socket in convergent footpath that forms by four rectangle quartz glass plates, the size of upper and lower two rectangle quartz glass plates wherein equates and is symmetrical arranged by wedge shape that the size of left and right two rectangle quartz glass plates equates and uprightly be bonded in by a glue both sides of upper and lower two rectangle quartz glass plates.Though this modular construction photoconductive tube is of a size of trapezoidal, but the silica glass material of forming its four limit need not be cut into trapezoidal plate again, be still rectangle, use the wedge shape mandrel, the mode of points of engagement glue, the size up and down of this structural change light shape, its collection efficiency, even light effect, shaping shape all are better than traditional rectangular light pipes.
The concrete technical scheme of another kind of the present utility model is: the photoconductive tube in the assembly can be one by last, the trapezoidal quartz glass plate and the left side of following two same sizes, the rectangle quartz glass plate of right two same sizes surrounds the trapezoidal socket in convergent footpath that forms, wherein, following two trapezoidal quartz glass plates are symmetrical arranged by wedge shape, a left side, right two rectangle quartz glass plates uprightly are bonded in by a glue, the both sides of following two trapezoidal quartz glass plates, this structure changes simultaneously to the light molded dimension on four limits, its collection efficiency, even light effect, the shaping shape all is better than equal rectangular light pipes, again because the outer mail of secure light pipe is shaped as rectangle rather than trapezoidal, can reduce the cost of section and outside mail like this, generally speaking cost can drop to almost identical with rectangular light pipes price.
Compared with prior art, result of use of the present utility model is good, cost is low, be easy to processing, its structural strength is identical with the rectangular light pipes of the viscose glues that adopt in a large number at present, reliability can reach requirement, the cost of finding this photoconductive tube by reality trial-production is approaching with viscose glue formula rectangular light pipes cost, and can reach light harvesting, even light and change the application requirements of light-changing type.
