Description

Technical Field

[0001] The invention belongs to the field of lamp technology, and in particular relates to a multi-purpose electrically adjustable focusing lamp. Background Art

[0002] At present, if the existing LED film and television lighting fixtures need to illuminate a large area with high illumination, many LED lamps must be hoisted on the frame to illuminate the object being filmed at the same time. However, this hoisting has the following disadvantages:

[0003] 1. The hoisting is inconvenient. Each time the hoisting is done, the first thing to do is to select the rack, and then calculate the number of hoisted lamps, including the weight, etc. At the same time, each time the disassembly and installation is used, a lot of manpower, material and financial resources are wasted;

[0004] 2. The lamp cannot be focused. Each time it is used, a fixed-angle beam barrel must be selected and replaced to change its irradiation area;

[0005] Moreover, because many individual lamp bodies are hung on the rack, there will be a problem of particularly obvious double shadow of the light emitted because it is not a single light source. Summary of the invention

[0006] The present invention aims to at least solve the problem that the LED film and television lighting fixture cannot be focused after being hoisted, and the problem of ghosting when using multiple single-light-source low-power lamps.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: A multi-purpose electrically adjustable focusing lamp proposed by the present invention includes a main body for installing the lamp, a hanging lamp bow is connected to the side of the main body, a base is provided at the bottom of the main body, and a liquid cooling station and a light source driving system located below the main body and a liquid cooling heat dissipation exhaust fan are respectively installed therein, and also includes:

[0008] Electric focusing mechanism: located in the main body, on which a light source is installed, the light emitting angle of the light source is 120°, emitting different lights and adjusting the distance through the electric focusing mechanism for focusing;

[0009] Reflective bowl: fixed in the main body, reflecting the light emitted by the light source;

[0010] Rotating mechanism: It is located below the electric focusing mechanism and connected to the electric focusing mechanism. The electric focusing mechanism is rotated 180° to switch between high and low color temperatures.

[0011] Glass: fixed on the side of the main body away from the reflective bowl and symmetrical with the reflective bowl to protect the light source.

[0012] As a preferred solution one: the electric focusing mechanism includes two groups of focusing slides fixed in the base, a focusing screw that rotates on the base and is parallel to the base is provided in the middle of the two focusing slides, a focusing sliding block is threadedly connected to the focusing screw, and the focusing sliding block is slidably connected to the focusing slide, a rotating bracket that rotates on the focusing sliding block passes through the focusing sliding block, the rotating bracket is connected to the rotating mechanism, the light source is provided at the top of the rotating bracket, and a focusing motor is connected to the end of the focusing screw.

[0013] As a second preferred solution: the rotating mechanism includes gear 1 arranged below the focusing sliding block, the gear 1 is connected to the rotating bracket, a rotating motor is also provided below the focusing sliding block, a gear 2 is provided on the output shaft of the rotating motor, and a rotating belt is wound between the gear 1 and the gear 2.

[0014] As a preferred solution three: the light source includes a lamp board radiator fixed on a rotating bracket, and color temperature lamp board assemblies are installed on both sides of the lamp board radiator. The color temperature lamp board assembly consists of a protective cover fixed on both sides of the lamp board radiator, and a color temperature lamp board positioned and installed on the light board radiator by the protective cover. The protective cover not only protects the color temperature lamp board, but also can install different optical glasses thereon to obtain different lighting effects.

[0015] As a fourth preferred solution: a retaining ring and a rear cover are respectively provided at the front and rear ends of the main body, and the glass is located on the retaining ring, and a color paper clamping claw extends from the circumferential surface close to the retaining ring.

[0016] As a fifth preferred solution: the light source driving system is electrically connected to the liquid cooling exhaust fan, the light source, the focusing motor and the rotating motor respectively.

[0017] As a sixth preferred solution: a heat dissipation fan is also provided on the focusing sliding block to achieve cooling.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows:

[0019] 1. Place the light source in front of a specially designed reflective bowl, which reflects 100% of the light emitted by the light source. The light efficiency is 50% higher than that of the traditional design, and the same power will get brighter illumination;

[0020] 2. At the same time, this equipment has an electric focusing function. With the electric focusing mechanism, engineers can operate the lamp from below after it is hoisted, so that they can easily get the light required by the scene; this design is different from the traditional design of focusing through Fresnel lens, because the light attenuation of Fresnel lens reaches between 30%-50%, while this design reduces the light attenuation to between 5%-10%;

[0021] 3. Furthermore, the rotating mechanism can improve the brightness while also satisfying the switching between high and low color temperatures;

[0022] 4. The liquid cooling station of this equipment can solve the problem of high-concentration heat dissipation, so that the power of the light source can be increased or decreased. BRIEF DESCRIPTION OF THE DRAWINGS
