Embodiment Construction

[0007] Below in conjunction with accompanying drawing, the utility model is described in detail.

[0008] The utility model is characterized in that its working circuit is sequentially connected with a DC12V storage battery and a DC / DC boost circuit, and the output ends of the DC / DC boost circuit are respectively connected to the xenon lamp for photography through a high-voltage ignition circuit and a DC and AC conversion circuit. The lamp tube voltage and current output by the xenon lamp are processed by the control and drive circuit and then fed back to the DC / DC step-up circuit and DC / AC conversion circuit at the same time. After the DC12V battery is exhausted, it will be charged by a 12V charger.

Abstract

A flash lamp used for photography, which uses a Xe lamp as the artificial light source.There are a storage battery and a boosting circuit in order in its working circuit.The output end of the boosting circuit is connected to the Xe lamp through a high voltage trigger circuit and a converter circuit.The voltage and current of the Xe lamp are processed by a controlling and driving circuit and then feeded back to the boosting circuit and the converter circuit synchronously.

Description

Technical field: [0001] The utility model relates to an artificial light source for camera and photography. Background technique: [0002] In general video cameras, in order to be able to take pictures under weak light conditions, a separate video light connected to the main body of the camera is required. Traditional video lights generally use tungsten filament lamps such as quartz lamps, iodine tungsten lamps, and halogen tungsten lamps as artificial light sources, which generate a large amount of heat, and the electrical energy is converted into useless heat. The user inflicts damage. On the other hand, since the power consumption is large, the usage time of the battery after one charge is short. If you want to extend the use time, you must use a battery that is large in size and weight. Tungsten lamps also have a short lifespan. Therefore, it is inconvenient to use and difficult to promote in cameras. Invention content: [0003] The purpose of the utility model is...
