Description
Technical field
The present invention relates to a kind of minitype projection machine, be specifically related to a kind of mobile phone minitype projection machine separate type fiber optic light source device.
Background technology
Minitype projection machine is the portable electronic consumer products of develop rapidly over the past two years, watches the big advantage of screen for a short time to carry volume, has not only obtained consumers in general's favor, and has had wide market application prospect.Current, along with improving constantly of micro projection machine technology, its volume has narrowed down to the degree that can be installed in the mobile phone, becomes the mobile phone minitype projection machine.This is one of the most fashionable instantly electric consumers.Yet when minitype projection machine became the wherein part of mobile phone, but produced a serious weak point owing to its volume is too small and exquisite: i.e. the brightness of minitype projection machine can not improve, thereby has influenced user's viewing effect.As, the brightness of existing common minitype projection machine can reach 15 lumens, and the brightness of mobile phone minitype projection machine can only reach 5 lumens, only be its 1/3.According to product analysis being caused the factor of this difference be: one, the volume of mobile phone minitype projection machine is too small and exquisite, the bigger cooling fan system of volume can't be set, the brightness of projection light source can't resolve heat dissipation problem, so just can not improve to the high-brightness projection light source; Two, the small and exquisite mobile phone minitype projection machine of volume own can't be installed high power battery, only with the used basic load of battery of mobile phone of conversation not high-brightness projection light source and the required power supply power consumption of cooling fan, thereby the brightness of projection light source can not improve.
In sum, this two large problems of light source heat radiation and power supply power consumption has not only directly influenced the raising of projection light source brightness, and has had a strong impact on the practical application request of consumers in general to the mobile phone minitype projection machine.Therefore, how to improve the projection brightness of mobile phone minitype projection machine? make the mobile phone minitype projection machine really enter the practical stage, be at present pendulum in the unusual stubborn problem of one of mobile phone minitype projection machine technical field.
Summary of the invention
In order to satisfy the functional need of vast electronic product consumer to the mobile phone minitype projection machine, overcome the existing low weak point of mobile phone minitype projection machine brightness, the present invention provides a kind of scheme of mobile phone minitype projection machine separate type fiber optic light source device according to existing in prior technology heat radiation and power consumption two large problems.Its principle is to have adopted the optical fibers technology of using always on the medicine equipment, the projection light source that is installed in projection ray machine inside in the minitype projection machine is separated to projection ray machine outside, and but the fibre-optic bundle that passes through the two ends plug connects the light source luminescent face and the image device sensitive surface of inside and outside, under the prerequisite of unattenuated projection light source intensity, making projection light source form one can independently external light source cell, that is to say to make it become an annex at random.Can cooling fan be installed and high capacity cell is provided to projection light source in this external annex, thereby the brightness of projection light source is increased substantially.
The present invention addresses the above problem the scheme that is adopted: a kind of mobile phone minitype projection machine separate type fiber optic light source device comprises mobile phone minitype projection machine, fibre-optic bundle and separate light source unit.It is characterized in that: the projection light source of the projection ray machine in the mobile phone minitype projection machine is separated external, form independent external separate light source unit.The fibre-optic bundle that use has certain-length transmits medium as light, light input end and light output end by fibre-optic bundle, connect the image device sensitive surface in the light-emitting area of separate light source unit inner projection light source and the projection ray machine respectively, make projection light source finish light source projects the projection ray machine with long distance light conduction pattern.Here the diameter of described fibre-optic bundle is 0.5～18mm, is provided with light input plug and light output plug at its two ends, is provided with protective sleeve on its surface.Described separate light source is provided with projection light source in the unit, is fixed with heat radiator thereon, is provided with heat radiation phoenix machine and supplying cell.On the phone housing of described mobile phone minitype projection machine, be provided with the light input socket that fibre-optic bundle connects the projection ray machine.On the shell of described separate light source unit, be provided with light accessory power outlet and battery charge socket.
In this programme, the fibre-optic bundle that is adopted is a kind of bending of light can the conduction, and be can only leaded light can not heat conduction medium, be usually used in optical-fibre communications and medical instruments field at present, as endoscope illumination system in the medical treatment etc.Characteristic according to this medium, just can change the prior art present situation of minitype projection machine fully, be about to the required higher source luminance of minitype projection machine, externally grow Distance Transmission, the high heat that produces because of high brightness just can not have influence on the inside of minitype projection machine like this, has the low thorny problem of brightness at present thereby solved the mobile phone minitype projection machine.
Advantage of the present invention is: a kind of mobile phone minitype projection machine separate type fiber optic light source device, the mode that adopts projection light source to separate with projection ray machine image device, by optical fibers transmission projection light source, not only improved the brightness of projection light source, solve the heat dissipation problem of higher source luminance, but also provide sufficient high capacity cell support for minitype projection machine.This device volume is small and exquisite to be easy to carry, when mobile phone need use projecting function, as long as the optical fibers that will install inserts mobile phone, go out the image of high brightness with regard to projectable, use very convenient, can satisfy the practical application request of consumers in general fully, the vast market promotion prospect is arranged the mobile phone minitype projection machine.
