Abstract
The invention discloses a mobile phone micro projection system which includes an LED light source and a condenser. The system is characterized in that: a Tacepro simulation method is used to design an array of a TIR condenser; an LED light source module is arranged before the array of the TIR condense; a back side of the LED light source module is fixed with a cooling plate; the outlet of the cooling plate is connected with a filtering device through a cooling pipe and a check valve A; the outlet of the filtering device is connected with the inlet of the cooling plate through a check valve B and the cooling pipe; light emitted by the LED light source module is compressed by a quasi value compression mirror before one TIR condenser and the quasi value compression mirror after the one TIR condenser, and is then further outputted by a DM color combination prism and a compound eye system. The brightness of the center of the visual field is increased by 50 times to reach 60Lm / W, so as to match the brightness of the business projector and fully meet the requirements of the projector.
Description
Technical field
The present invention relates to a kind of optical projection system, relate in particular to the micro-optical projection system of a kind of mobile phone.
Background technology
As everyone knows, optical projection system is the requisite equipment of a lot of occasions, no matter is products propaganda, still trains various students, all needs to carry out live play with projector equipment, introduces and explanation to facilitate.But projector equipment generally has larger volume, carry and use all extremely inconvenient.Along with the continuous enhancing of the universal and cell-phone function of mobile phone, the sixth of the twelve Earthly Branches is through having the people in research micro-optical projection system of design and installation one in mobile phone now, still, size is large owing to existing, field luminance not, cost is higher and can't promote the use of.
Summary of the invention
The object of the invention is to provide in order to overcome the deficiencies in the prior art a kind of and can meet field luminance requirement, physical dimension is suitable, cost the is low micro-optical projection system of a kind of mobile phone.Concrete technical scheme is: the micro-optical projection system of a kind of mobile phone, comprise LED light source, condenser, with Tacepro analogy method design an array TIR condenser, before condenser, be provided with a LED light source module, the back side of LED light source module is fixed with a coldplate, cooling tube is passed through in the outlet of coldplate, retaining valve A connects a filtration unit, cooling tube is passed through in the outlet of filtration unit, retaining valve B is connected with the import of coldplate, the light that the LED light source module sends by accurate value compressional mirror and a TIR condenser before a TIR condenser after accurate value compressional mirror compress after again through the DM color-combination prism, the output of compound eye system.
Said LED light source module is that 54 LED light sources of one or six row nine row form.
In said LED light source module, each 18 of red, green, blues, its specification is 1 * 1mm
2.
In said filtration unit, evenly be interval with filter.
From technical scheme of the present invention, can find out, due to the increase of LED light-emitting area, its field of view center brightness will increase 50 times, reach 60Lm/w, and this brightness reaches the brightness of business's thing projector, meets the requirement of projector fully.Simultaneously, owing to having adopted cooling structure of the present invention, in the time of the work of LED light source module, the heat that light source the produces liquid that is cooled absorbs.When absorbing energy and reaching the value of defining of system, retaining valve A opens, and the liquid that absorbs heat energy enters cooling tube, release energy with filtering system in impurity.Retaining valve B opens simultaneously, enters cooling tube through overcooled liquid, the heat energy produced while absorbing the work of LED light source module.Then enter next circulation, reach reciprocation cycle with this, when the LED light source module quit work, corresponding cooling system just can stop circulation.Cooling system can reach pressure equilibrium automatically, and the cooling surface of liquid is large, cooling effectiveness is high, and filtration unit more makes it increase radiating surface, and the impurity that in filtration unit, the tube wall material different with filter medium well produces in filtering system, the stability of keeping system.So structure can be less, cost also reduces greatly, has realized meeting field luminance requirement, physical dimension is suitable, cost is low goal of the invention fully.
