Description

Technical Field

[0001] This utility model relates to the field of work light technology, specifically a work light with snow melting function. Background Technology

[0002] Currently, common vehicle work lights on the market (such as engineering vehicle lights, off-road auxiliary lights, and special vehicle warning lights) have significant functional defects in cold climates or icy and snowy environments. The main problem is the lack of active snow-melting capability, leading to the following issues:

[0003] (1) Snow cover causes lighting failure: The outer lens surface of traditional work lights is prone to snow accumulation and ice formation in snowy weather, and there is no active heating function, resulting in a decrease in luminous flux of more than 50%, which seriously affects work safety. For example, after a mining truck works in a -20℃ environment for 1 hour, the snow thickness on the lamp cover can reach 3-5mm, and the brightness is only 30%.

[0004] (2) Low snow removal efficiency: Some vehicles use passive measures such as manual snow scraping or spraying antifreeze, which frequently stops to clean up and reduces work efficiency (manual intervention is required every 2 hours). Antifreeze corrodes the lamp housing sealing material (such as EPDM rubber aging speed is 3 times faster).

[0005] No solutions have yet been proposed for the relevant technical issues. Utility Model Content

[0006] To address the problems in related technologies, this utility model proposes a work light with snow-melting function to overcome the aforementioned technical problems in existing related technologies. The purpose of this utility model is to achieve reliable all-weather lighting, ensure operational safety, reduce manual operation, extend the service life of the work light, and prevent the work light from deforming due to the weight of accumulated snow. Compared with traditional electroplated conductive coating snow melting, it greatly reduces the cost of snow melting function.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a work light with snow melting function, comprising a lamp body, an outer cover connected to one side of the lamp body, an outer cover panel, an inner cover, a decorative frame, a reflector cup and a circuit board arranged sequentially between the lamp body and the outer cover, and a plurality of ceramic heating elements arranged between the decorative frame and the reflector cup.

Two limiting plates are provided, located on both sides of the fixing protrusion. Each of the two limiting plates has a fixing groove that matches the fixing protrusion. Several adjusting blocks are provided on the opposite sides of the two limiting plates. Adjusting grooves that match the adjusting blocks are provided on the inner walls of both sides of the support. The base is located at the bottom of the support. One end of the screw passes through one side of the base, one side of the support, one of the limiting plates, the other limiting plate, the other side of the support, and the other side of the base in sequence, and the end extends to the outside of the base and is threadedly connected to the nut.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1

[0025] Please see Figure 1-3 This utility model proposes a technical solution for a work light with snow-melting function: A work light with snow-melting function includes a lamp body 1, an outer cover 2 connected to one side of the lamp body 1, and an outer cover panel 3, an inner cover 4, a decorative frame 5, a reflector cup 6 and a circuit board 7 arranged sequentially between the lamp body 1 and the outer cover 2. Several ceramic heating elements 8 are arranged between the decorative frame 5 and the reflector cup 6. Specifically, the ceramic heating elements 8 provide heat to melt the snow.

[0026] In this embodiment, the snow melting function is achieved by setting an inner cover 4, a decorative frame 5, a reflector cup 6, and a ceramic heating element 8, using a laminated structure to reduce the cost of use.

[0027] Please see Figure 1-3 As shown, a rotating base 10 is further provided at the bottom of the lamp body 1.

[0028] In this embodiment, the rotating base 10 can adjust the angle of the lamp body 1.

[0029] Please see Figure 1-3As shown, the rotating base 10 further includes a fixing protrusion 1001, a limiting plate 1002, a support 1003, a screw 1004, a nut 1005, and a base 1006. The fixing protrusion 1001 is fixedly installed at the bottom of the lamp body 1. Two limiting plates 1002 are provided, located on both sides of the fixing protrusion 1001 respectively. Both limiting plates 1002 have fixing grooves that match the fixing protrusion 1001. Several adjustment points are provided on the opposite sides of the two limiting plates 1002. The inner walls of both sides of the block 1007 and the support 1003 are provided with adjustment grooves 1008 that match the adjustment block 1007. The base 1006 is located at the bottom of the support 1003. One end of the screw 1004 passes through one side of the base 1006, one side of the support 1003, one limiting plate 1002, another limiting plate 1002, the other side of the support 1003 and the other side of the base 1006 in sequence, and the end extends to the outside of the base 1006 and is threadedly connected to the nut 1005.

[0030] In this embodiment, the bottom end of the fixing protrusion 1001 is respectively inserted into the fixing groove of the two limiting plates 1002 to facilitate the connection between the lamp body 1 and the rotating seat 10. By rotating the limiting plate 1002, the adjusting block 1007 on the limiting plate 1002 is rotated. The angle of the adjusting block 1007 when it is inserted into different adjusting grooves 1008 on the support 1003 is different. The limiting plate 1002 can be fixed by the nut 1005 to prevent loosening after the angle is adjusted. The base 1006 plays a supporting role.

[0031] Please see Figure 1-3 As shown, furthermore, the outer cover 2 is provided with several card plates 11, and the lamp body 1 is provided with several card slots that match the card plates 11.

[0032] In this embodiment, four card plates 11 are provided to facilitate the connection between the outer cover 2 and the lamp body 1.

[0033] Please see Figure 1-3 As shown, the support 1003 is further provided with fixing screws 12.

[0034] In this embodiment, the lamp body 1 is easy to install in the required position, and the installation and disassembly steps are simple.

[0035] Furthermore, the decorative frame 5 is made of aluminum.

[0036] In this embodiment, the service life of the decorative frame 5 is extended.

[0037] Please see Figure 3As shown, further, the outer cover panel 3 is mounted on the outer cover 2 by screw one, the circuit board 7 is mounted on the lamp body 1 by screw two, and two ceramic heating elements 8 are provided, and are respectively mounted on the left and right sides of the reflector cup 6 by screw three.

[0038] In this embodiment, installation and disassembly are convenient, improving practicality and facilitating later maintenance and repair.

[0039] Please see Figure 1-3 As shown, furthermore, the lamp body 1 is also provided with several heat dissipation fins 13.

[0040] In this embodiment, the heat dissipation fins 13 effectively accelerate the dissipation of heat.

[0041] This invention utilizes a ceramic heating element 8 for snow melting. The ceramic heating element 8 reaches its operating temperature (60-80℃) in 3-5 seconds and can melt 5mm thick snow (in an environment of -20℃) within 5 minutes, significantly reducing the time required for traditional manual snow removal or natural melting (usually more than 30 minutes). The PTC characteristic automatically limits the maximum temperature to prevent overheating and damage to the lens (e.g., the upper temperature limit of PC material is about 120℃), while ensuring optimal energy consumption, long service life, and low power consumption. The ceramic heating element 8 is only 0.5-1.2mm thick, allowing it to be directly attached to the inner wall of the lens or embedded in the lamp body structure without altering the original appearance. Furthermore, the ceramic heating element 8 has a flame retardant rating of UL94 V-0, eliminating the risk of open flame and meeting the safety standards for mining / explosion-proof scenarios. It does not affect the light performance (transmittance > 90%) and meets ECE / SAE regulatory requirements.

[0044] In this embodiment, the cost of use is reduced and the practicality is improved.
