Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, specifically to a double-helix LED industrial and mining lamp. Background Technology

[0002] LED industrial and mining lamps have been widely used, and LED industrial and mining lamps with variable beam angles can meet the complex and diverse lighting requirements of factories with fewer types of lamps, making them a hot development trend in LED industrial and mining lamps.

[0003] Patent document CN222047538U discloses a variable beam angle industrial lamp, which adjusts the beam angle by rotating a rotating lens to change the relative position of the rotating lens and the lighting components. Patent document CN213542255U discloses a spiral ceiling light, which improves luminous efficiency and light source utilization by covering LED beads with a spiral lens. However, in actual production activities, such as... Figure 7 As shown, for single-spiral LED industrial and mining lamps, when mounting color-temperature adjustable LED light sources on a PCB board, it is difficult to arrange the traces of LEDs with two different color temperatures in a cross pattern, resulting in insufficient spacing between the LED light sources and affecting the improvement of luminous efficiency. At the same time, in order to facilitate circuit layout, the radial distance between the inner and outer coils of the spiral lens needs to be greater than 10mm. This results in a smaller number of LEDs that can be accommodated on the PCB board, leading to poor luminous efficiency of the industrial and mining lamp.

[0004] Therefore, how to improve the ease of wiring for LED industrial and mining lamps has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a double-helix LED industrial and mining lamp to address the above-mentioned technical problems, so as to improve the wiring convenience of the LED industrial and mining lamp and improve the luminous efficiency of the LED industrial and mining lamp.

[0006] The technical solution adopted in this utility model is: a double-helix LED industrial and mining lamp, comprising:

[0007] Lamp housing;

[0008] PCB board, which is installed inside the lamp housing;

[0009] A double-helix lens is mounted on the side of the PCB board away from the lamp housing. The double-helix lens includes a first helical protrusion and a second helical protrusion, which are alternately arranged in the radial direction. A first helical receiving groove and a second helical receiving groove that are concave upward are formed on the lower surface of the double-helix lens. The first helical receiving groove is located directly below the first helical protrusion, and the second helical receiving groove is located directly below the second helical protrusion.

[0010] LED light sources, with multiple LED light sources spirally distributed on the PCB board and located in the first spiral receiving groove and the second spiral receiving groove.

[0011] Preferably, the double-helix lens includes a lens body, the edge of which is detachably and fixedly connected to the lamp housing. A first helical protrusion and a second helical protrusion are integrally formed on the upper surface of the lens body, and a first helical receiving groove and a second helical receiving groove are formed on the lower surface of the lens body.

[0012] Preferably, the radial distance between two adjacent spiral segments of the first or second spiral protrusion is 9 mm.

[0013] Preferably, the mirror body is provided with an indicator arrow, and multiple indicator marks that cooperate with the indicator arrow are provided on the edge of the PCB board.

[0014] Preferably, the mirror body has 10 connecting through holes evenly distributed around its edge, and connecting screws are installed in the connecting through holes and are threadedly connected to the lamp housing.

[0015] Preferably, the mirror body is made of PC material.

[0016] Preferably, the LED light source includes low color temperature LEDs and high color temperature LEDs, with a plurality of low color temperature LEDs spirally distributed in a first spiral receiving groove and a plurality of high color temperature LEDs spirally distributed in a second spiral receiving groove.

[0017] Preferably, the power of the low color temperature LED and the high color temperature LED is 0.5W~1W.

[0018] Preferably, the package size of the low color temperature LED and the high color temperature LED is 2.8mm*3.5mm or 3.0mm*3.0mm.

[0019] The beneficial effects of this utility model are:

[0020] This invention utilizes a double-helix structure, with a first helical protrusion and a second helical protrusion formed on the upper surface of the double-helix lens. A first helical receiving groove and a second helical receiving groove, corresponding to the first and second helical protrusions respectively, are formed on the lower surface of the double-helix lens. Multiple LED light sources are helically distributed on the PCB board below the first and second helical receiving grooves. This not only allows LED light sources of different color temperatures to be distributed in different helical receiving grooves and achieves cross-arrangement of LED light sources of different color temperatures in the radial direction, enabling convenient routing of LED light sources, but also reduces the radial distance between the inner and outer coils of the helical lens, allowing a larger number of LED light sources to be arranged on the PCB board, thereby improving the luminous efficiency of LED industrial and mining lamps.

The first helical protrusion 32 and the second helical protrusion 33 have the same helical direction and are alternately arranged in the radial direction. That is, the first helical protrusion 32 and the second helical protrusion 33 are formed on the upper surface of the lens body 31.
