Focusing cylinder for high-power LED spotlight for shooting

Abstract

The invention discloses a focusing cylinder for a high-power LED spotlight for shooting and aims at solving the problem that by considering to adopt electric exhaust to efficiently lower a temperaturein the focusing cylinder, an external power line needs to be externally induced to become an encumbrance of the focusing cylinder and increase the disassembling and assembling workload, and a lamp main body is not provided with a connectable power supply socket, so that electric exhaust cannot be reasonably realized. The technical key points are as follows: the focusing cylinder comprises a cylinder body rear part which is connected with the lamp main body, a cylinder body front part, the front side of the which is provided with a condensing lens and a rotating focusing ring which is matchedwith the front part and the rear part of the cylinder body and is used for controlling the front part of the cylinder body to move; and the rear wall surface of the rear part of the cylinder body is provided with a light-passing window which is matched with an LED light source. The focusing cylinder is characterized in that the inner wall of the rear part of the cylinder body or the front part ofthe cylinder body is fixedly provided with a photocell panel; an electric cooling fan is fixedly installed on the wall part of the rear part of the cylinder body or the front part of the cylinder body; and the electric output end of the photocell panel is electrically connected with the power input end of the electric cooling fan.

Description

technical field [0001] The invention relates to lighting equipment for shooting, in particular to a focusing tube for high-power LED spotlights for shooting. It is suitable for focusing tubes that can be disassembled and separated. Background technique [0002] At present, LED spotlights are commonly used for shooting, and are generally used in outdoor shooting occasions, photography studios, studios, conference rooms, studios, multi-functional halls, theater auditoriums and other occasions. The structure of the LED spotlight for shooting of the same kind includes a light body and a focusing tube installed in front of the light body. The focusing tube is an independent component that can be disassembled and separated. The focusing tube structure is generally composed of the rear part of the tube connected to the main body of the lamp, the front part of the tube with a condenser lens on the front side, and the rotating focusing ring matched on the front and rear parts of the...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the consideration of using electric exhaust to reduce the temperature inside the focusing tube of the LED spotlight for shooting more efficiently, there must be an external power line, which becomes a burden on the focusing tube and increases the workload of disassembly. The plug interface of the external power supply has caused the problem that the electric exhaust cannot be reasonably realized at present. The purpose of the present invention is to provide an improved focusing tube for high-power LED spotlights for shooting, which can overcome the defects of the prior art
