Abstract

The invention discloses an LED projection lamp with a telescopic function. The LED projection lamp comprises a lamp box, a lamp body regulation and control device is arranged in the lamp box, and a projection lamp shell is connected to the lamp body regulation and control device. A spiral cooling device and a projection lamp body are arranged in the projection lamp shell. The spiral cooling deviceis used for uniformly cooling the projection lamp body. A sealing mechanism is further arranged on the lamp box. The degree of freedom of the projection lamp body can be adjusted through the lamp body regulation and control device, and the flexibility of the projection lamp body is improved; the spiral cooling device arranged in the projection lamp shell can uniformly cool the projection lamp body, and the use effect of the projection lamp is improved; and the projection lamp body can be stored in the lamp box through the lamp body regulation and control device and sealed through the sealingmechanism, external dust is prevented from entering the projection lamp body, loss of the projection lamp body under severe conditions is reduced, the projection lamp body is protected, and collisionand friction of the projection lamp body are prevented.

Description

technical field

[0001] The invention relates to the technical field of lighting equipment, in particular to an LED floodlight with telescoping function. Background technique

[0002] LED floodlights are also called spotlights, projection lights, spotlights, etc. They are mainly used for architectural decoration lighting and commercial space lighting. Traditional spotlights are different. For example, in a Chinese patent with an application date of 2018.06.14, a publication number of CN110608371A, and an invention titled "A LED Flood-light Lamp That Facilitates Adjusting the Lighting Angle", a new type of LED Flood-light Lamp is disclosed. However, the aforementioned patent is in In actual use, there are still the following problems:

[0003] 1. The projection lamp in the above patent can only adjust the projection angle, but cannot adjust the degree of freedom of the projection lamp body, which has poor flexibility, and the cooling and heat dissipation of the projection la...

Embodiment Construction

[0027] In order to better understand the present invention, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0028] Such as Figure 1 to Figure 5 As shown, an LED floodlight with a telescopic function includes a light box 1. A lamp body control device 2 is arranged inside the light box 1. A floodlight housing 3 is connected to the lamp body control device 2. Inside the floodlight housing 3 The spiral cooling device 4 and the projection lamp body 5 are respectively provided, and the projection lamp body 5 is uniformly cooled by the spiral cooling device 4. The light box 1 is also provided with a closing mechanism 10. When the projection lamp body 5 needs to be used, Open the closing mechanism 10, use the lamp body control device 2 to transport the floodlight housing 3 and the floodlight body 5 to the outside of the light box 1, and adjust the degree of freedom of the floodlight body 5 according to actual...
