Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a working lamp with adjustable lens angle. Background Art

[0002] The conventional angle-changing method on the market is to change the focal length, which uses a light board or lens to promote the zoom to achieve the angle change. The lens angle is not accurately controlled and has a large tolerance when the focal length is pushed to change the angle. It is not easy to control waterproofing when pushing. There is also a kind of industrial and mining lamp that directly adds a set of lens accessories to replace the lens to change the angle. Conventional industrial and mining lamps are of a single angle, which is usually 60°, 90°, and 120°. Customers then buy other angles as accessories. If industrial and mining lamps with lenses of different angles need to be processed, multiple lens accessories of different angles are purchased to increase the inventory of lenses. If the three angles are combined in one lens on the existing industrial lamp, the overall size of the product will be larger and the cost will be relatively high. Utility Model Content

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Reference Figure 1 As shown, the working condition lamp with adjustable lens angle described in the utility model comprises: a lamp holder 1; an LED lamp board 2, which is arranged on the lamp holder 1 and electrically connected to the lamp holder 1, and the LED lamp board 2 is provided with an indicating angle; a heat dissipation structure 3, which is arranged around the lamp holder 1 for dissipating heat to the LED lamp board 2, and a lens 4, which is rotatably arranged on the outside of the LED lamp board 2, and the edge of the lens 4 is locked and fixed to the LED lamp board 2 by fasteners; a Fermat spiral curve 5 is provided on the lens 4, and a hollow indicating arrow 6 is provided at the edge of the lens 4. When it is necessary to adjust the angle of the lens 4, the fasteners at the edge of the lens 4 are removed, and the lens 4 is started to rotate. When the indicating arrow 6 is aligned with a certain indicating angle on the LED lamp board 2, the indicating angle can be seen from the hollow indicating arrow 6, which is convenient for the staff to observe the indicating angle, and then the lens 4 is fixed to the LED lamp board 2, so as to achieve the angle adjustment of the lens 4. The rotating lens 4 in this embodiment can be adjusted at multiple angles, which reduces excess inventory and the disposal of plastic waste, which is of certain significance to carbon neutrality. Customers can reduce material preparation costs and increase profits.

[0029] like Figure 2 and 3As shown, the heat dissipation structure 3 includes a heat dissipation plate 31, heat dissipation ribs 32 and an air convection combination plate 33. The heat dissipation ribs 32 are radiated from the center of the heat dissipation plate 31, and the air convection combination plate 33 is arranged around the heat dissipation plate 31. The air convection combination plate 33 includes a first convection plate 331 and a second convection plate 332. A plurality of heat dissipation holes 333 are evenly spaced on the first convection plate 331 and the second convection plate 332. The first convection plate 331 and the convection plate 332 are arranged at an angle, and the heat dissipation holes 333 on the first convection plate 331 and the heat dissipation holes 333 on the second convection plate 332 correspond to each other one by one. The heat on the LED light board 2 can be transferred through the heat dissipation plate 31, and the heat dissipation ribs 32 further dissipate the heat. The angle design of the first convection plate 331 and the second convection plate 332 can enable the heat dissipation holes 333 on the first convection plate 331 and the second convection plate 332 to perform air convection, thereby enhancing the heat dissipation effect of the heat dissipation structure 3.

[0030] In this embodiment, the back of the heat sink 31 is provided with a plurality of bolt locking fixing seats 34. When the working condition light needs to be fixed on the wall, the bolts can be inserted into the bolt locking fixing seats 34 to fix the working condition light. In addition, a hanging ring 11 is provided at the center of the back of the lamp holder 1. When the hanging ring 11 is used for lighting, the lamp holder 1 will be hoisted for use, meeting various installation requirements of the working condition light.

[0031] In this embodiment, the lamp holder 1 is provided with a power switching button 12 and a color temperature switching button 13. The working lamp integrates the functions of switching power and color temperature with a sensor. The power of the working lamp is switched by operating the power switching button 12. The working lamp can realize 150w and 200w. When the color temperature needs to be changed, it is changed through the color temperature switching button 13 to meet the lighting needs of industrial and mining lamps.

[0032] like Figure 4 and 5 As shown, the indication angles include 60°, 90° and 120°, and the above three indication angles are set at intervals of 120°. If the original angle is 60°, remove the fasteners between the lens 4 and the LED light board 2 (the fasteners here are screws), turn the lens 4 120 degrees, and then install the screws. The angle will change from the original 60° to 90°. After the product removes the screws, turn it 120° again, and then install it. The angle will change from the original 90° to 120°. Customers only need to buy one working condition light that is compatible with three angles, which helps to greatly reduce the purchase cost.

[0033] Preferably, a protrusion 40 is provided in the middle of the lens 4 , a sensing plate 7 is provided in the cavity of the protrusion 40 , and the sensing plate 7 is electrically connected to the lamp holder 1 ; and the Fermat spiral curve 5 is provided around the protrusion 40 .

[0034] In this embodiment, a circular hole 401 is provided in the middle of the protrusion 40 for installing a sensing element with microwave or infrared sensing function. A sealing plug 402 is provided on the circular hole 401. When the circular hole 401 does not need to be embedded with a sensing element, the circular hole 401 is sealed by the sealing plug 402.

[0035] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
