Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail:
External flash lamp described in the utility model, be placed in the outside of the smart machine with camera function, here smart machine refers to smart mobile phone, panel computer of having camera function etc., the smart mobile phone (being equipped with APP/IOS software) of take is below example, and the composition structure of described external flash lamp is described.
With reference to Fig. 1, described external flash lamp comprises main control unit 1 and the communication unit, photosensitive unit 8, flashing light unit 4 and the power subsystem that are connected with described main control unit 1 communication respectively, described power supply is also electrically connected to flashing light unit 4, is main control unit 1 and flashing light unit 4 power supplies simultaneously.
Particularly, power subsystem comprises battery 2, battery charging and discharging control unit 5, voltage regulation unit 9 and boosting rectifier control unit 3, described battery 2 is electrically connected to voltage regulation unit 9 by battery charging and discharging control unit 5, described battery 2 is also electrically connected to flashing light unit 4 by boosting rectifier control unit 3, and described boosting rectifier control unit 3 and battery charging and discharging control unit 5 are electrically connected to described main control unit 1 respectively.
Communication unit, described communication unit is connected with outside smart mobile phone communication, for receiving the flash command that smart mobile phone sends and this flash command being transferred to main control unit 1.Described communication unit can be also radio communication unit 7 for wire communication unit 6, or is both combination.Wherein, wire communication unit 6 can adopt data wire, that is, main control unit 1 is realized on-line real-time by data wire and smart mobile phone; In addition, radio communication unit 7 is Wi-Fi signal and communication unit, infrared signal communication unit, Bluetooth signal communication unit or above-mentioned combination, and main control unit 1 is realized online without time delay by Wi-Fi wireless communication mode, wireless infrared communication mode or blue tooth wireless communication mode and smart mobile phone.
Photosensitive unit 8, for perception from the light signal of outside input and by this optical signal transmission to main control unit 1.Described photosensitive unit 8 is the photometry control head of high inspiration degree, can realize like a cork the luminous index that regulates photoflash lamp according to the power of natural daylight.
The lamp source of flashing light unit 4 adopts xenon lamp, to guarantee colour temperature, lumen value and stroboscopic efficiency and continuous working period.
