Description
Technical field
The utility model relates generally to a kind of desk lamp with projecting function.
Background technology
Desk lamp is widely used in people's the routine work and study as a kind of illuminations.In the working and learning process, people usually need to view and admire reading some videos, image or written historical materials, and perhaps the short time amusement is loosened to adjust current state, raising work or learning efficiency.It is contemplated that, if desk lamp has projecting function, people only need carry out simple key-press operation, need not to open multimedia tool such as TV, display, just can very easily these videos, image or written historical materials be projected to surroundings wall or roof is viewed and admired reading.And, after work and study gap or tired work and study, also can open the projecting function of desk lamp easily, loosen fully lie on a bed or sofa on heartily appreciation movie and video programs.
Traditional projector not only volume is big but also cost an arm and a leg, and its embedding can not be applied on the desk lamp.LED (Light Emitting Diode) has compact conformation as the projection lighting light source, and (LED can directly send R, G, three kinds of primary lights of B or white light, simplified the light channel structure of projector), (LED is a cold light source in environmental protection and energy saving, caloric value is low, and non-radiating ultraviolet light and infrared light), advantages such as the life-span is long, obtained global numerous projection manufacturer and consumer's favor, promote the micro projection technology and not broken hair exhibition occurs, the more and more littler manufacturing cost of appearance and size of minitype projection machine is also more and more lower at present, make shadow casting technique be penetrated into unapproachable market segment in the past gradually, be applied to mobile phone as embedding, digital camera, mobile devices such as notebook computer, increase the function and the attraction of the said goods, had vast market prospect.The appearance of small size, low-cost micro projection technology and development also provide the foundation for we develop a kind of popular desk lamp with projecting function.
The utility model content
The utility model does not have the actual conditions of projecting function desk lamp at existing market, a kind of desk lamp with projecting function of embedded minitype projection module is provided, the user can be in work and study, can open the projecting function of desk lamp when needed, video, image or literal are projected to the wall aid reading, also can be after work and study gap or work and study fatigue, open the projecting function of desk lamp, video, image or literal are projected to wall appreciate, experience for the user provides a kind of brand-new high-tech.
For achieving the above object, the utility model has adopted following technical proposals: design a kind of desk lamp with projecting function, it is to embed minitype projection module on the conventional table modulated structure, and this desk lamp not only has the illumination functions that general desk lamp provides, and also has projecting function.About the general lighting function of this desk lamp,, no longer describe in detail because everybody knows.The projecting function of this desk lamp is realized that by embedded minitype projection module this embedded minitype projection module comprises input module, power module, signal processing module and projection module four parts.Wherein first three module embeds and is installed in Desk lamp feet, and projection module embeds and is installed on the desk lamp lamp holder, data wire, power line in the desk lamp pole by and the projection module of lamp holder and other module of base coupled together.
This input module comprises card reader interface, video input interface, USB interface and VGA computer signal interface, be used to receive the data such as video, image or literal of external equipment, these data comprise data, cd resource, television video frequency signal, flash memory disk or the data on hard disc of memory card and other data of importing by USB interface and VGA computer signal interface.The data message that input module receives all input interfaces is sent to signal processing module and carries out data processing and conversion.
This power module can be dc-battery power supply, DC line power supply or the electric supply installation that interchange is converted to direct current for light path illumination, data reception and the image processing of this minitype projection module provide electric energy.
This signal processing module carries out computing and processing with the data message that input module provides, and with computing and the conversion after the photoelectricity signal be input to led chip and LCOS chip, LCOS carries out image modulation to the LED polarised light that receives, and the light modulated of having carried picture signal is reflected away.
This projection module comprises led light source, condenser, PBS, projection driving, LCOS and projection lens, the light path of projection module is as shown in Figure 4: red, green, blue primary lights that LED sends or white light are after condenser converges, enter the PBS polarization manipulation, polarised light is entered LCOS by the PBS reflection and carries out image modulation, and the light modulated of having carried picture signal enters projection lens and projects on the screen.(promptly three kinds of primary lights are luminous in turn chronologically because led light source can directly send R, G, three kinds of primary lights of B and realize the separately fast break-make of three kinds of primary lights, timesharing arrives optical projection system fast), need not just can be applicable to projector through complicated and accurate colour wheel (Color Wheel) beam splitting system, simplify the light channel structure of projector, reduced the size of this projection module greatly.This projection drives and is used to drive the LCOS chip with the sequential of control LCOS acceptance pattern as red, green, blue optical information and liquid crystal reaction, and driving LED is with the luminous sequential and the frequency of three kinds of primary lights of control LED.
This described projection module can be fixedly mounted on the correct position of desk lamp lampshade, also can be installed in the correct position of desk lamp lampshade by heads such as rotating shaft, screw threads.Itself can not move hard-wired projection module or rotate, can only or rotate by the mobile of desk lamp fuselage and change projecting direction and angle, realize that by adjusting the desk lamp fuselage projection optical axis is vertical with projection screen, avoid occurring the projected picture trapezoidal distortion, also can realize the picture trapezoidal correction by in projection module, increasing the trapezoidal correction function.Can realize that by the projection module that heads such as rotating shaft, screw thread are installed 0 °-360 ° are rotated or move, the user can arbitraryly project image onto the multiple different angles and the position of surroundings wall and roof, avoid the obstacle between projection lens and perspective plane, lock pleasant and projection angle and position clearly.And rotating shaft and screw thread have auto-lock function, and it is motionless to stop at this angle after rotation finishes, because the image trapezoidal distortion that optical axis and curtain wall out of plumb cause can be corrected by the embedded trapezoidal correction function of projection module.
Certainly, the utility model also can be designed to all four modules with minitype projection module, be that input module, power module, signal processing module and projection module are assembled in the same movable component, and this movable component is movably arranged in desk lamp lampshade or the base, the user can select to buy and projecting subassembly is installed or not bought the installation projecting subassembly according to the needs of oneself.
Pass through technique scheme, thereby this utility model has following beneficial effect: the user can be in work and study, can open the projecting function of desk lamp when needed, video, image or literal are projected to the wall aid reading, also can be after work and study gap or work and study fatigue, open the projecting function of desk lamp, video, image or literal are projected to wall appreciate, experience for the user provides a kind of brand-new high-tech.
