Underwater strobe lamp and underwater strobe lamp frequency and duty-ratio regulating method

Abstract

The present invention discloses an underwater strobe lamp, and the underwater strobe lamp comprises at least one lamp body unit. The lamp body units are connected to a T-connector via watertight cables, and the T-connector is connected to a controller via cables. The controller is provided with a first nixie tube, a second nixie tube, a frequency regulating potentiometer, a duty-ratio regulating potentiometer and a switch. Each lamp body unit comprises a lamp body, and the lamp body comprises a lighting source. Each lighting source is arranged in the front end of a cylindrical body, a driving circuit board is arranged in the middle of the cylindrical body and the driving circuit board is mounted on a supporting plate. Each supporting plate is connected with the inner wall of the corresponding cylindrical body, each lighting source is connected to the corresponding driving circuit board, each driving circuit board is connected to a socket, and the socket is arranged on a sealing rear cover. The underwater strobe lamp can solve the existing problems of a conventional strobe lamp, for example, the conventional strobe lamp is not capable of meeting the demand of underwater usage, frequency and duty-ratio regulation and underwater photography supplemental lighting and auxiliary lighting.

Description

technical field [0001] The invention relates to an underwater observation device, an underwater strobe light, in particular to an underwater strobe light and a method for adjusting its frequency and duty cycle. Background technique [0002] At present, strobe lights have been widely used in camera supplementary light and auxiliary lighting. The lamp body with higher illuminance is often bulky, and the control method of strobe lights is usually level triggering, which cannot realize remote operation control The flashing frequency and duty cycle are fixed. In special application fields, such as supplementary light for propeller blade cavitation observation in scientific research, higher requirements are placed on the frequency and duty cycle accuracy of the strobe light. The underwater LED strobe light with adjustable frequency and duty ratio involved in the present invention realizes flexible and adjustable frequency and duty ratio, with a frequency accuracy of 2% and a duty...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an underwater strobe light and a method for adjusting its frequency and duty cycle, which can solve the problem that the existing strobe light cannot be used underwater, and the frequency and duty cycle cannot be adjusted. Meet the needs of supplementary lighting and auxiliary lighting for underwater photography
