Description

Technical Field

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

[0002] In existing vehicle lighting systems, headlights are generally designed to emit light horizontally. For example, Chinese utility model patent application number 202322508715.5 discloses a combined automotive LED work light, which includes a device body and LED bulbs. While this design meets the basic lighting needs of vehicles on flat roads or under normal driving conditions to some extent, it has revealed many limitations in practical applications.

[0003] Because light travels only horizontally, its illumination range is strictly limited and cannot effectively cover a large area around the vehicle. Especially when the vehicle needs to turn, change lanes, go up or down slopes, or is in complex terrain (such as rugged mountain roads, construction sites, etc.), the driver's field of vision is significantly limited, making it difficult to detect obstacles, pedestrians or other potential dangers around the vehicle in advance, thus greatly increasing the risk to driving safety. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a work light with a warning light function.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A work light with a warning light function includes a lamp body and a lamp holder mounted on the lamp body. The lamp body is fixed to a vehicle by the lamp holder. The lamp body includes a housing, a warning light module, an LED light module, and a lamp cover. The warning light module is installed in the upper part of the housing, and the LED light module is installed in the lower part of the housing. The lamp cover is placed over the light outlet at the front end of the housing. The lamp cover includes a warning light working area and an LED light working area. The warning light working area is aligned with the warning light module, and the LED light working area is aligned with the LED light module. The lamp cover has a forward-protruding trapezoidal structure. The inclined surfaces on both sides of the lamp cover are set as diffusion surfaces. The angle between the diffusion surfaces on both sides and the front end face is 30°. When the light shines from the lamp cover, it forms a 180° illumination range through the front end face and the diffusion surfaces on both sides.

[0007] In this invention, a diffusion edge extends horizontally inward from the bottom edge of the LED working area on the lampshade. The cross-section of the LED working area is L-shaped. Part of the light emitted by the LED module is emitted from the LED working area, and the other part is emitted from the diffusion edge.

[0008] Furthermore, the LED lamp module includes an LED lamp circuit board and a heat dissipation bracket. The heat dissipation bracket is fixed inside the housing at the position corresponding to the working area of ​​the LED lamp. The heat dissipation bracket is also provided with a mounting surface for mounting the LED lamp circuit board. The mounting surface is inclined at a 45° angle to the front end of the lamp cover. After the LED lamp circuit board is mounted on the mounting surface, it shines at a 45° angle downwards, thereby forming a 135° illumination angle.

[0009] In this utility model, the warning light module includes a warning light circuit board and a warning light lens. The warning light circuit board is installed inside the housing, and the warning light lens is installed in the warning light working area after being aligned with the warning light circuit board.

[0010] Furthermore, the warning light lens and the lamp cover are integrally formed.

[0011] In this utility model, the rear part of the housing is provided with a connecting part for connecting the lamp holder. The lamp holder is a fixed bracket. The fixed bracket is rotatably mounted on the connecting part. The fixed bracket includes a U-shaped bracket and a fixing bolt. The U-shaped bracket is hinged to the connecting part by a rotating shaft. The fixing bolt fixes the U-shaped bracket to the vehicle.

[0012] Furthermore, the lamp holder is a flange frame, which is fitted onto the rear of the lamp body and connected to the housing by bolts. The lamp body is fixed to the vehicle by the flange frame.

[0013] This utility model has the following advantages and beneficial effects:

[0014] By designing the entire lamp cover as a forward-protruding trapezoidal structure, with the two diffuser surfaces forming a 30° angle with the front surface, and extending the diffuser horizontally inward at the bottom edge of the LED working area to form an L-shaped structure, combined with the 45° angled illumination of the LED circuit board, the illumination angle in both the left and right and up and down directions is effectively increased, resulting in a larger illumination range. This solves the problem of limited illumination range caused by the horizontal beams of existing vehicle lighting systems, which leads to limited driver visibility and high driving safety risks when turning, changing lanes, going up and down slopes, or on complex terrain. At the same time, the warning light lens and lamp cover are integrally molded, reducing the number of light propagation times and improving brightness.

[0015] In addition, the lamp holder adopts two structures: a fixed bracket or a flange frame. The fixed bracket can be rotated to adjust the angle of the lamp body, while the flange frame improves the stability of the lamp body, further enhancing the practicality and safety of the work lamp.

[0025] like Figures 1 to 5As shown, this embodiment discloses a work light with a warning light function, including a lamp body 1 and a lamp holder 2 mounted on the lamp body 1. The lamp body 1 is fixed to the vehicle by the lamp holder 2. The lamp body 1 includes a housing 11, a warning light module 12, an LED light module 13, and a lamp cover 14. The warning light module 12 is installed in the upper part of the housing 11, and the LED light module 13 is installed in the lower part of the housing 11. The lamp cover 14 covers the light outlet at the front end of the housing 11. The lamp cover 14 includes a warning light working area 3 and an LED light working area 4. The warning light working area 3 is aligned with the warning light module 13. The indicator light module 12 has its LED light working area 4 aligned with the LED light module 13. Specifically, to increase the illumination angle in the left and right directions, the lampshade 14 is designed as a forward-protruding trapezoidal structure. The inclined surfaces on both sides of the lampshade 14 are designed as diffusion surfaces 141. The angle between the diffusion surfaces 141 on both sides and the front face 140 is 30°. In this way, when light shines from the lampshade 14, part of the light is emitted from the front face 140 of the lampshade 14, and the other part of the light is emitted from the diffusion surfaces 141 on both sides, thereby forming a 180° illumination range, which greatly improves the illumination angle.

[0026] In this embodiment, in order to increase the vertical illumination angle of the LED lamp working area 4, a diffusion edge 142 extends horizontally inward from the bottom edge of the LED lamp working area 4 on the lamp cover 14, making the cross-section of the LED lamp working area 4 L-shaped. Part of the light emitted by the LED lamp module 13 is emitted from the LED working area, and the other part is emitted from the diffusion edge 142, thereby increasing the vertical illumination angle. Specifically, in order to match the L-shaped structure of the LED lamp working area 4, the LED lamp module 13 includes an LED lamp circuit board 131 and a heat sink bracket 132. The heat sink bracket 132 is fixed inside the housing 11 at the position corresponding to the LED lamp working area 4. The heat sink bracket 132 is also provided with a mounting surface 133 for mounting the LED lamp circuit board 131. The mounting surface 133 is inclined at a 45° angle to the front end face 140 of the lamp cover 14. After the LED lamp circuit board 131 is mounted on the mounting surface 133, it irradiates downward at a 45° angle, thereby making the LED lamp working area 4 form a 135° illumination angle.

[0027] In this embodiment, the warning light module 12 includes a warning light circuit board 121 and a warning light lens 122. The warning light circuit board 121 is installed inside the housing 11. The warning light lens 122 is aligned with the warning light circuit board 121 and installed in the warning light working area 3. Preferably, the warning light lens 122 is integrated into the lamp cover 14, that is, the warning light lens 122 and the lamp cover 14 are integrally formed. When the LED on the warning light circuit board 121 emits light, the light is directly emitted through the warning light lens 122, reducing the number of light propagation times and improving brightness.

[0028] In this embodiment, the rear of the housing 11 is provided with a connecting part 111 for connecting the lamp holder 2. The lamp holder 2 is a fixed bracket 21 or a flange frame 22. When the lamp holder 2 is a fixed bracket 21, the fixed bracket 21 is rotatably mounted on the connecting part 111. The fixed bracket 21 includes a U-shaped bracket 211 and a fixing bolt 212. The U-shaped bracket 211 is hinged to the connecting part 111 through a rotating shaft 213. The fixing bolt 212 fixes the U-shaped bracket 211 to the vehicle. Preferably, the rotating shaft 213 is a screw and a nut, which can be tightened to adjust the angle of the lamp body 1.

[0029] When the lamp holder 2 is a flange frame 22, the flange frame 22 is fitted onto the rear part of the lamp body 1 and connected to the housing 11 by bolts. Then the flange frame 22 is fixed on the vehicle to form a fixed shape, which improves stability and prevents the light from shaking.

[0030] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
