Abstract
The utility model discloses an annular conversion device of a flash lamp of a camera, which comprises a condensing box, an optical fiber cable and an annular flash ring, wherein an opening which is matched with a flash lamp of the camera is arranged at one end of the condensing box, and the other end of the condensing box is connected with the optical fiber cable; a port which is matched with a camera lens is arranged on one side of the annular flash ring, and a plurality of diffusing elements are evenly distributed on the annular end surface of the other side; and the diffusing elements are respectively connected with optical fibers in the optical fiber cable. When in use, the condensing box is sheathed on the ordinary flash lamp of the camera, and the annular flash ring is fixed on the camera lens. A light source of the flash lamp is focused through the condensing box, and then the light source is conducted to a diffusing lens of the annular flash ring through the optical fiber cable, thereby achieving small loss of the light source, uniform flash and the availability to use with a variety of lenses. The device has the advantages of simple structure, environmental protection, simple operation, convenient carrying and the like.
Description
Technical field
The utility model relates to a kind of camera flashlamp annex, relates in particular to a kind of camera flashlamp annular conversion equipment that the ordinary camera flashlamp can be converted to doughnut-shaped flash lamp.
Background technology
Doughnut-shaped flash lamp is one of camera flash light fixture of using always, and special when carrying out microshot, doughnut-shaped flash lamp has been indispensable Flash lamps and lanterns.Then, common in the market doughnut-shaped flash lamp costs an arm and a leg, and function singleness.Increase the acquisition cost of photographic equipment greatly, and caused the significant wastage of resource easily.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of camera flashlamp annular conversion equipment that common flashlamp can be converted to doughnut-shaped flash lamp is provided, characteristics such as that this conversion equipment has is simple in structure, with low cost, of many uses, be convenient for carrying and the light conduction loss is atomic, the flashlamp that is used band TTL pattern can be realized flash of light and photometry automatically.
In order to achieve the above object, the utility model has adopted following technical scheme:
A kind of camera flashlamp annular conversion equipment comprises optically focused box, optical fiber cable and annular flash of light circle, and optically focused box one end is provided with the opening that cooperates with camera flashlamp, and the other end is connected with optical fiber cable; Annular flash of light circle one side is provided with the port that matches with camera lens, is evenly distributed with several astigmatic elements on the annular end face of opposite side; The astigmatism element is connected with optical fiber in the optical fiber cable respectively.
Be provided with light source with flashlamp in the described optically focused box and be gathered in beam condensing unit on the optical fiber cable.
Described beam condensing unit is a collector lens.
Described astigmatic element is an astigmat.
Owing to adopted said structure, camera flashlamp annular conversion equipment of the present utility model is sheathed on the optically focused box on the common flashlamp of camera in use, annular flash of light circle is fixed on the camera lens to get final product simultaneously.Assemble the light source of flashlamp by the optically focused box after, light source conducts on the annular astigmat that encloses that glistens by optical fiber cable and glistens, loss of light source is little, flash of light is even and can cooperate multiple camera lens to use, have simple in structure, environmental protection, easy and simple to handle, be convenient for carrying and advantage such as the light conduction loss is atomic, the flashlamp that is used band TTL pattern can be realized flash of light and photometry automatically.
