Description
Technical field
What the present invention relates to is a kind of led light source light-collecting module, particularly be that a kind of clamping device that utilizes is with a kind of led light source light-collecting module and clamping device thereof on the optical collector LED pedestal that is fixed on projector fast and accurately.
Background technology
Because advancing by leaps and bounds of high-tech technology especially maked rapid progress in the field of microelectronics correlation technique processing procedure especially in recent years, so the electronic correlation product has been embedded in each family and all trades and professions, becomes some indispensable in the modern life.
Certainly because human wants is more and more, make electronic installation must reach the use of greater functionality relatively, and each electronic product more stride forward towards the target of short and small frivolous structure and diversification effect.In numerous electronic goods, the development of projector and application, also all the more extensively convenient human life.And along with projector's development of technology, projector's product is because volume is little, in light weight, easy to carry, add that the mobile computer performance constantly promotes day by day to increase with sales volume and popularize, and then it is in fashion also to drive the multimedia bulletin.Make script just based on projector's product in office automation (OA) market, following except the consumer electronics market development, also will cut personal computer (PC) market.And the development trend of whole projector product concentrates on functional promotion, price reduction and three directions of volume-diminished.
With the present less relatively DLP projector of volume on the market, its principle is to include shown in figure one: a light source module A (Illuminator Module), a collector lens B (Condenser), a prism group C (Prism Module), a digital micromirror device D (Digital Micro-mirror Device; DMD) and a projection lens group E (Projection Lens Set).The light of being launched from light source module A, earlier after collector lens B assembles, by prism group C light is folded to the described digital micromirror device D of directive, after digital micromirror device D reflection and video picture, by prism group C light is folded to projection lens group E once more, and is focused on for being imaged on an extraneous projecting plane F.
As for described light source module A, it is mainly formed (as shown in Figure 2) by three the led light source light-collecting module G and most optical filter H that can send red, blue, green three kinds of different colours, wherein said each led light source light-collecting module G further is made up of LED pedestal I and optical collector J (collimator), and its brightness is concentrated and promoted to the light that described optical collector J can be produced the last LED K of LED pedestal I.Therefore, whether the relative position of described optical collector J and LED K correctly will have influence on the collection efficiency of described optical collector J.
Because the characteristic of optical collector J (collimator) requires and can not too much contacting be arranged with clamping or fixing structure, otherwise can have influence on the efficient of light harvesting.Therefore, how accurately and simplify clamp structure, become the required effort of dealer and go to overcome the problem that research and development and careful consideration solve to be adapted at a large amount of productions.
Summary of the invention
Fundamental purpose of the present invention, be to provide a kind of led light source light-collecting module and clamping device thereof, it is the accurate and LED pedestal positioning and fixing with optical collector fast, simultaneously, surface of contact between described clamping device and the optical collector is also minimized, to obtain best collection efficiency.
Another object of the present invention is the clamping device that is to provide a kind of led light source light-collecting module, utilizes the clamping device of a symmetrical expression, can effectively save die cost, promotes its price competitiveness.
Another object of the present invention is the clamping device that is to provide a kind of led light source light-collecting module, by modular design, promotes the assembling convenience of product, can effectively promote the quality and the degree of stability of product.
For reaching above-mentioned purpose, the technical solution used in the present invention is, a kind of led light source light-collecting module is provided, and it is mainly by comprising that a LED pedestal, an optical collector and a clamping device are formed.Wherein, described clamping device further is made up of one first grip block and one second grip block.Described first grip block and second grip block are can fast optical collector be gripped within it and utilize a fastening structure to give quick snap fit between the two.On the other hand, then be to utilize a location mechanism to provide described clamping device to be fixed on accurately on the LED pedestal between described clamping device and the LED pedestal.
In a preferred embodiment, on optical collector, more be provided with a collar flange, and the relative position on first and second grip block is respectively equipped with a groove that can cooperate with described collar flange.Only be to cooperate with the clamping of groove, promptly be enough to make optical collector by firm clamping and be positioned between first and second grip block by described collar flange.In other words, described optical collector except its collar flange can by the groove clamping of first and second grip block with contact, the other parts of described optical collector all can not touch other any part of first and second grip block.Make that the surface of contact between optical collector and other assembly is minimized, and then promote the collection efficiency of optical collector relatively.
