Description

Technical Field

[0001] The utility model relates to the technical field, in particular to an adjustable-focus mining lamp with an independent heat dissipation function. Background Art

[0002] The selection of mining area lighting fixtures needs to be determined according to the actual environment, safety requirements and work needs of the mining area. LED lamps can provide high brightness and concentrated light, effectively illuminate narrow spaces such as mines, and meet the strict lighting requirements of mining areas. However, in actual use, there are usually the following three problems, resulting in large light scattering losses and low efficiency. First, the light emitted by the light source itself diffuses in space and fails to effectively concentrate on the target area; second, the reflector distributes defocus loss. When the reflector reflects light, due to uneven distribution or unreasonable design, the light fails to form an ideal focusing effect, resulting in energy loss; finally, the focal length of the lens limits the focal irradiation area. The focal length of the lens determines the focusing degree and irradiation range of the light. If the focal length is too short or too long, it will limit the focal irradiation area, thereby affecting the lighting effect.

[0003] In order to improve lighting efficiency, we need to optimize and improve these losses to ensure that light can more accurately illuminate the target, reduce scattering losses, and improve lighting quality. In addition, traditional lighting fixtures often cannot meet the actual needs of the problem of insufficient lighting brightness in ultra-high-rise factories. Especially in high-temperature areas such as smelting and steel rolling, lighting fixtures are not only easily damaged, but also have a greatly reduced lighting effect. Utility Model Content

[0017] There are four radiators 2.

[0018] The lower periphery of the tempered glass 11 is fixed to the housing 1 through a stainless steel pressing ring 12 to prevent the tempered glass from loosening or being damaged.

[0019] The surface of the radiator 2 is provided with cooling fins to enhance the heat dissipation effect.

[0020] The shaft sleeve 4 is provided with lubricating grease inside to reduce the friction resistance of the connecting rod 5 in the shaft sleeve 4 and improve the smoothness of focusing.

[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0022] First of all, the working principle of the present application mainly relies on the coordinated work of the light-emitting chip 3 and multiple independent heat sinks 2. The light-emitting chip 3 serves as a light source and is responsible for generating light. At the same time, in order to ensure the stable operation of the light-emitting chip 3 and extend its service life, the heat sink 2 is designed to effectively dissipate the heat generated by the light-emitting chip 3 during operation. During operation, the heat generated by the light-emitting chip 3 is quickly dispersed and discharged into the environment through the heat dissipation fins of the heat sink 2, thereby ensuring the normal operation of the light-emitting chip 3. At the same time, due to the design of the housing 1, it also effectively prevents external dust and debris from interfering with the light-emitting chip 3 and the heat sink 2, further improving its working stability.

[0023] The focusing principle of the mining lamp mainly relies on the coordinated action of the tuning screw 6, the connecting rod 5, the lens assembly 8, the guide rod 9 and the spring 10. When the user needs to adjust the focus of the light, the tuning screw 6 can be rotated. Since the tuning screw 6 and the connecting rod 5 are threadedly connected, rotating the tuning screw 6 will cause the connecting rod 5 to move up and down in the sleeve 4. The bottom end of the connecting rod 5 is connected to the lens assembly 8 through the fixing bolt 7, so the movement of the connecting rod 5 will drive the lens assembly 8 to move together.

[0024] During the movement of the lens assembly 8, the guide rod 9 and the spring 10 play a guiding and buffering role. The guide rod 9 ensures the stability of the lens assembly 8 during the movement and prevents it from deviating from the track. The spring 10 provides a buffering effect, so that the lens assembly 8 can move smoothly during the process of adjusting the focus, avoiding damage or position displacement caused by sudden impact or vibration.

[0025] By adjusting the position of the lens assembly 8, the user can change the focus of the light, thereby adjusting the illumination range and brightness of the light. This design enables the mining lamp to adapt to different environments and lighting requirements, greatly improving its flexibility and practicality of use.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
