Description
Technical field
The utility model relates to a kind of LED light device, is a kind of multifunctional high-power integrated LED flash lamp for photography specifically.
Background technology
Lighting is one of equipment indispensable in movies-making process.Along with the progress of science and technology, video display lamp experienced by from stages such as incandescent lamp, tungsten halogen lamp, metal halide lamp, xenon short-act lamps.In recent years, due to development and the maturation of LED technology, revolutionary development was brought to lighting technology.Video display light fixture also more and more employs LED technology.Vehicles Collected from Market also occurs bring some photography and vedio recording lamps using LED light source conveniently to the illumination of news interview, wedding celebration, shooting and light filling.But these light fixtures adopt discrete direct insertion LED mostly, because single led brightness is inadequate, dozens of, even hundreds of LED are usually used to be arranged in two-way array, its power supply also uses outside lithium battery mostly in addition, causes these light fixture volumes comparatively large, but still underpower, brightness is inadequate, and its function is simple, it is convenient not to portably use, and is difficult to meet the demand of going out to take.
Chinese utility model patent specification CN203686949U discloses a kind of chargeable video display lamp of built-in lithium battery, employs 80-120 LED and is arranged in ellipse, built-in lithium battery and power supply adaptor, and uses monolithic computer to control electric fan to dispel the heat for LED.Whole apparatus structure is complicated, and volume is comparatively large, uses inconvenience.
US Patent specification US2010/0014274A1 discloses a kind of photoflash lamp of LED matrix, and employing is many
Individual LED is arranged in matrix, uses brightness and the time of a control circuit control LED, to save electric energy and to prevent LED overheated.This lamp is mainly used in the photo illumination light filling of short time, is not suitable for long camera operation.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of structure simple, portably use conveniently, function is relatively complete, can meet the photography and vedio recording lamp of general spot coverage photographing request.
For solving the problems of the technologies described above, the utility model is realized by following technical proposal, and it comprises: input power interface, lithium battery, LED drive circuit, out-put supply interface, intednsity circuit, LED selection circuit, two groups of integrated LEDs.LED drive circuit input is connected with input power interface and lithium battery respectively, and its output is connected with out-put supply interface and intednsity circuit, and intednsity circuit is connected with LED selection circuit, and LED selection circuit is connected with two groups of integrated LEDs respectively.
External input power or built-in lithium battery power supply can change into and can meet high-power integrated LED and normally to work required voltage and current by LED drive circuit of the present utility model, lead up to intednsity circuit and LED selection circuit, light two groups of integrated LEDs respectively, and control its brightness; Another road, as out-put supply, is supplied to other electronic equipments as stand-by power supply, and external power supply also can charge for built-in lithium battery.The LED that the utility model uses is the integrated high power LED adopting chip on board (COB) to encapsulate, and is characterized in that volume is little, power is large, brightness is high, greatly reduces the volume of light fixture; Two groups of integrated LEDs can use the integrated LED of identical colour temperature or different-colour.
Compared with prior art, the utility model has following beneficial effect: use integrated high power LED, volume is little, power is large, brightness is high; External power supply or built-in lithium battery can be used to power for equipment, and external power supply also can charge for built-in lithium battery; Identical colour temperature or different-colour integrated LED can be used, meet different photography demand; By brilliance control, the power-on time of lithium battery can be extended; There is out-put supply interface, stand-by power supply can be provided for some video camera or relevant device.
