[0002] Industrial and mining lamps are high-efficiency indoor LED lamps that can be widely used in industrial plants, production workshops, supermarkets, sports and entertainment venues, warehouses, etc. General industrial and mining lamps are composed of power boxes, radiators, lampshades, light sources and lenses. They have simple structures and single functions.

[0003] When existing industrial and mining lamps are in use, their luminous power and color temperature are generally unchanged, which makes it impossible for them to take into account the lighting needs of different scenarios. They have a structure that can adjust the luminous power and color temperature of the light source. However, as people's demand for the functional use of lamps increases, the existence of this problem will limit the application scope of industrial and mining lamps. In addition, although the structure of existing industrial and mining lamps is simple, the number of its components is still relatively large. Therefore, when assembling industrial and mining lamps, too many components will affect the assembly efficiency and are not conducive to the development of industrial and mining lamps towards miniaturization.

DETAILED DESCRIPTION

[0020] The utility model discloses a mining lamp with a simple structure. Figures 1 to 3 As shown in combination, the mining lamp includes a power box 1, a radiator 2 and a lampshade 3, the lampshade 3 is connected to the bottom end of the radiator 2, and the bottom of the radiator 2 is connected with a first PCB4 and a lens 5 in sequence from top to bottom. The first PCB4 is provided with a plurality of light sources 41, and the power box 1 is integrally formed in the middle of the radiator 2. A first cavity 11 and a second cavity 12 are provided in the power box 1, and a second PCB6 is fixedly connected in the first cavity 11. The second PCB6 integrates a control chip 61 and a power supply 62, and a dial module switch 7 electrically connected to the control chip 61 is provided in the second cavity 12. The control chip 61 is electrically connected to the first PCB4, and a matching hole 13 is provided on the top surface of the power box 1 above the dial module switch 7, and the matching hole 13 is matched with a plug 8.

[0021] It should be noted that the dial module switch 7 in the mining lamp adopts a small modular design, the structure of the control components in the mining lamp is simplified, and the dial module switch 7 is set in the second cavity 12 in the power box 1 for protection. After unscrewing the plug 8 that seals the second cavity 12 where the dip module switch 7 is located, the operator can adjust the dip module switch 7. The action of the dip module switch 7 forms an electrical signal transmitted to the control chip 61. The control chip 61 controls the power and color temperature of the light source 41 to adjust the power and color temperature, thereby realizing the dial adjustment of the power and color temperature of the light source 41, which is easy to operate. Moreover, the power box 1 is integrated into the design of the radiator 2, thereby further simplifying the structure of the top of the mining lamp and making the assembly operation of the mining lamp more convenient.

[0022] It needs to be further explained that, Figures 2 to 4As shown in combination, the dip module switch 7 includes a first dip switch 71 for adjusting the luminous power of the light source 41, a second dip switch 72 for adjusting the color temperature of the light source 41, and a third PCB 73. The third PCB 73 is fixedly connected in the second cavity 12 and electrically connected to the control chip 61. The first dip switch 71 and the second dip switch 72 are both arranged on the third PCB 73. The working ends of the first dip switch 71 and the second dip switch 72 are both facing the matching hole 13.

[0023] Among them, after unscrewing the plug 8 from the matching hole 13, by toggling the working end of the first dial switch 71, the first dial switch 71 can form an electrical signal and transmit it to the control chip 61. The control chip 61 adjusts the luminous power of the light source 41 according to the electrical signal control, thereby adjusting the brightness of the light source 41, and by toggling the working end of the second dial switch 72, the second dial switch 72 can form an electrical signal and transmit it to the control chip 61. The control chip 61 controls the color temperature of the light source 41 according to the electrical signal control, thereby adjusting the light color of the light source 41.

[0024] It needs to be further explained that, Figure 5 As shown, the surface of the plug 8 is provided with an external thread section 81, and the matching hole 13 is an internal thread hole. The plug 8 is matched with the matching hole 13 by means of internal and external threads.

[0025] The plug 8 is engaged with the mating hole 13 by means of a threaded engagement, so that the plug 8 can be re-engaged in the mating hole 13 after the power and color temperature of the light source 41 are adjusted by dialing, and the mating hole 13 continues to be sealed.

[0026] It needs to be further explained that, Figure 2 and Figure 6 As shown in the figure, the plug 8 is a pin 82, and the plug 8 is fitted in the fitting hole 13 by interference fit.

[0027] When it is necessary to perform a dial operation to adjust the power and color temperature of the light source 41, the matching hole 13 above the second cavity 12 is opened by destroying the pin 82, so that the operator can adjust the dial module switch 7 in the second cavity 12. After the adjustment is completed, a new pin 82 is installed into the matching hole 13 to complete the sealing of the matching hole 13.

[0028] It needs to be further explained that, Figure 2 As shown, a plurality of heat dissipation fins 21 are provided on the circumference of the top surface of the radiator 2 , and the ends of the heat dissipation fins 21 close to the middle of the radiator 2 are integrally formed on the outer wall of the power box 1 .

[0029] Among them, the heat dissipation fins 21 on the radiator 2 are integrally formed with the power box 1. Not only can the heat energy in the power box 1 be transferred to the heat dissipation fins 21 by heat conduction when the industrial and mining lamp is working, so that the heat dissipation of the internal power box 1 is cooled by using the heat dissipation fins 21, making the internal heat dissipation of the power box 1 faster, but also the design of the heat dissipation fins 21 and the power box 1 being integrally formed can make the top of the industrial and mining lamp more beautiful.

[0030] It needs to be further explained that, Figure 7 As shown, a plurality of waist holes 31 are provided on the circumferential edge of the top of the lampshade 3 , and a plurality of connection holes 22 are provided on the circumferential edge of the bottom of the radiator 2 , the positions of which correspond to the waist holes 31 above and below.

[0031] Among them, the connection between the lampshade 3 and the radiator 2 is achieved by inserting the connecting components into the waist hole 31 and the connecting hole 22. The setting of the waist hole 31 makes it easier for the connecting components to align with the position of the connecting hole 22 when the lampshade 3 is connected to the radiator 2, avoiding the phenomenon that the position on the lampshade 3 for connecting the connecting components cannot be aligned with the connecting hole 22 after the lampshade 3 is deformed, thereby ensuring that the lampshade 3 can be normally connected to the radiator 2.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
