The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to Fig. 1; The flashlight of a kind of LED of the having micro projector that provides for the utility model; Comprise lamp tube 2, place the switch 3 on lamp tube 2 outer walls and place illuminator 1 and the battery 4 in the lamp tube 2, also be provided with LED micro projector 5 in the said lamp tube 2, also be provided with external tapping on said lamp tube 2 outer walls; Said illuminator 1 is connected with said battery 4 two ends respectively with said LED micro projector 5, and said switch 5 two ends are connected with said LED micro projector 5 with said illuminator 1 respectively.Said illuminator 1 promptly can be common flashlight miniature bulb, also LED lamp.And the great advantage of the utility model is that micro projector 5 is applied on the flashlight; Structure is simple relatively, volume is little, make things convenient for daily life to carry and use; Make that the cost of manufacture of the utility model is lower, and need not the maintenance cost in later stage basically, economical and practical.
Referring to Fig. 2, the circuit diagram of the flashlight that provides for the utility model embodiment, the circuit of illuminator 1 and LED micro projector 5 is connected with battery 4 respectively among the figure.3 on switch is divided into three gears, has controlled three kinds of duties of the utility model respectively.When switch 3 places the left side, when being connected with the negative pole of left side illuminator 1, illuminator 1 is communicated with battery 4, and the utility model uses as flashlight; In the middle of switch 3 placed, illuminator 1 all broke off with battery 4 with LED micro projector 5 and being connected, and neither uses; When switch 3 places the right, when being connected with the negative pole of the LED micro projector 5 on the right, LED micro projector 5 is communicated with battery 4, and the utility model uses as projecting apparatus.The battery 4 that the utility model adopted is the jumbo rechargeable lithium batteries of reusable edible.This battery capacity is bigger, can guarantee no matter be the long-time electric weight supply of using of flashlight or projecting apparatus.TunePower also can be protected environment, recycle.
Please again referring to Fig. 1; In the concrete example structure of the utility model; Said LED micro projector 5 comprises control circuit board 51, micro projection module 52, video data interface 53 and universal data interface 54; Said video data interface 53 places on the said control circuit board 51 and with said lamp tube 2 external tappings with universal data interface 54 and is connected, and said micro projection module 52 is electrically connected with said control circuit board 51.Particularly, described video data interface 53 can be HDMI interface, perhaps these type of video data interfaces such as Video interface, S-Video interface, VGA interface; Described universal data interface can be USB interface etc.The utlity model has the maximum advantage of LED micro projector is exactly that its volume is urinated in carrying, and is fit to the field man and uses, because its volume is little, can takes out at any time and do demonstration.The tourism personage also can bring the appreciation photo on the road, sees a film or the like, and the amusement that has increased tourism is interesting, plays the function of dual-use material.The utility model can connect electronic equipments such as computer, mobile phone, MP4, IPAD, IPHONE, DVD, VCD, TV, top box of digital machine through described universal data interface or video data interface simultaneously; Can the video section of this kind equipment be transferred in the LED micro projector, project through the utility model again.Tent during one colourless wall is perhaps camped just can be used as projection screen, does not receive the limitation in place, can increase the scope of application of projecting apparatus as the place of using everywhere, has enlarged the use crowd of projecting apparatus.
Further, said micro projection module 52 comprises projective LED lamp 521, said LED lamp 521 light sources is divided into trichromatic projection ray machine 522, the three primary colors analyzing and processing is become the display chip 523 of data image and the projection lens 524 that the image projection of handling well is come out.
Particularly, described display chip 523 is a dmd chip, i.e. the data micro-mirror device.Dmd chip is the core component of DLP shadow casting technique.DLP shadow casting technique is the digital light treatment technology, and its core component is DMD, and this technology is to want to advance digital processing to signal of video signal earlier to project light again.The DLP technology is that a kind of optical semiconductor that adopts produces the solution that digital multiple light courcess shows, the optimized image effect can be provided.Its main operation principle is after white light that projective LED lamp 521 is sent resolves into R, G, B three primary colors through projection ray machine 522; Project on the dmd chip 523; Forms by a lot of small eyeglasses on the dmd chip 523, each eyeglass all can-10 ° with+rotate freely and locate between 10 ° by electric charge, signal input acts on dmd chip 523 after treatment; Thereby the deflection of control eyeglass, incident ray arrives projection lens 524 projection imagings after through the reflection of DMD eyeglass.Adopt the shadow casting technique of dmd chip, improved the tonal gradation of image, picture noise disappears, and image quality is stable, and digital picture is very accurate, and contrast, brightness, the uniformity are all very good, and definition is high, picture is even, color is sharp keen.
Particularly, described display chip 523 is the LCOS chip.The core component that gives the LCOS shadow casting technique of reflected light path is exactly the LCOS chip, and the basic structure of this chip is to cover the liquid crystal molecular coatings on the back plane circuitry of CMOS.Its operation principle is that the white light of at first projective LED lamp 521 being sent is divided into R, G, B three primary colors through projection ray machine 522; Then; Each primary colors light shines on the LCOS chip 523 of a blocks of reflecting; System changes the power of each pixel reflection ray of this chip block through the state of liquid crystal molecule on the control LCOS panel 523; The light that the most laggard LCOS of mistake chip 523 reflects pools Ray Of Light through the light refraction of necessity, shines on the screen through projector lens 524, forms colored image.Adopt the shadow casting technique of LCOS chip, utilize that optical efficiency is high, volume is little, high-resolution, resolution is high, power saving.
More than be merely the preferred embodiment of the utility model,, any modification of being done within all spirit at the utility model and the principle, be equal to and replace and improvement etc., all should be included within the protection domain of the utility model not in order to restriction the utility model.
