Embodiment 1

[0029] see Figure 1-3 , the present invention provides a technical solution: an automatic focusing spotlight, including a spotlight body 1, a control switch 5, a heat dissipation device 14, a heat dissipation window 19 and an adjustment mechanism 26 are respectively installed on the spotlight body 1, and the spotlight body The position corresponding to the heat dissipation window 19 on 1 is detachably connected to the dustproof device 12 through the connecting mechanism 20, the shock absorbing device 25 is installed on the adjusting mechanism 26, the zoom ring 16 is installed on the shock absorbing device 25, and the light outlet of the spotlight body 1 The position is detachably connected to the light blocking device 13 through the clamping mechanism 24, and the input end of the control switch 5 is electrically connected to the output end of the external power supply.

Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is:

[0032] In this embodiment, the heat dissipation device 14 includes a heat-conducting silica gel sheet 10, which is attached to the spotlight body 1, and the heat-conducting silica gel sheet 10 is evenly provided with cooling fins 11, and the heat-conducting silica gel sheet 10 generated during the working process of the spotlight body 1 The heat is gathered on the heat-conducting silica gel sheet 10, and the heat on the heat-conducting silica gel sheet 10 is dissipated through the cooling fins 11, which has a good heat dissipation effect and is convenient for the spotlight to work efficiently.

[0033] The dust-proof device 12 includes a frame 3, on which a dust-proof net 2 is installed, and the dust-proof net 2 is used to prevent external dust from entering its interior through the heat dissipation window 19 on the spotlight body 1, which greatly increases the service life of the spotlight .

[0034] The co...

Embodiment 1-2

[0041] The focusing method of embodiment 1-2 comprises the following steps:

[0042] A. The heat generated by the spotlight body 1 during the working process gathers on the heat-conducting silica gel sheet 10, and the heat on the heat-conducting silica gel sheet 10 is dissipated through the cooling fins 11;

[0043] B. The dust-proof net 2 is used to prevent external dust from entering the interior of the spotlight body 1 through the heat dissipation window 19;

[0044] C. Connect the frame 3 with the spotlight body 1 through the magnetic strip 4 and the magnetic connection of the adsorption hoop 21;

[0045] D. Control the work of the linear motor 23 through the control switch 5. The linear motor 23 makes a linear motion on the guide rail 22 through the slider. The linear motor 23 drives the zoom ring 16 away from or close to the light source through the shock absorber 25, so as to adjust the focus;

[0046] E, the bad vibration that the zoom ring 16 receives is eliminated b...

Abstract

The invention discloses an automatic focusing spotlight and a focusing method thereof. The automatic focusing spotlight includes a focusing spotlight body. The spotlight body is provided with a control switch, a heat dissipation device, a heat dissipation window and an adjusting mechanism. A dustproof device is detachably connected to a position, which corresponds to the heat dissipation window, on the spotlight body through a connection mechanism. The spotlight focusing method is good in heat dissipation effect, facilitates the efficient work of the spotlight, has dustproof capability, greatly increase the service life of the spotlight, is convenient in disassembly, and is in convenient in the cleaning of a dustproof net. A zoom ring is driven by the adjusting mechanism away from or neara light source so as to focus, which is convenient in adjustment and facilitates the switching of different optical requirements. Negative vibration of the zoom ring is eliminated by a shock absorbingdevice, which facilitates the stable work of the spotlight. Light emitted by the spotlight body is blocked by a light blocking device so as to adjust the shape of projection, which greatly improves the working ability of the spotlight.

Description

technical field [0001] The invention relates to the technical field of spotlight focusing, in particular to an automatic focusing spotlight and a focusing method thereof. Background technique [0002] In the prior art: the patent application publication number CN 105404090 A discloses a lens focusing device and a focusing method thereof. By placing the lens module to be focused on the focusing positioning device of the lens module, the lens module The focusing and positioning device will automatically bring the lens module to the focusing station to ensure the accuracy of the focusing and positioning of the lens module. The control system automatically completes the focusing of the lens module, and the focusing and positioning device of the lens module automatically drives the lens module to return to its original position after the focusing is completed; [0003] The existing spotlights cannot be adjusted to change the light spot, the heat dissipation effect is poor, and t...
