[0029] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions.

[0030] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0031] Example 1

[0032] See also Figures 1 to 5 , a lamp, which is a work lamp and can be used as an outdoor camping lamp.

[0033] The lamp of this embodiment includes a lamp body 1, a housing 2, and an outer cover 3. The lamp body 1 includes a lamp holder 11. The lamp holder 11 includes a first shell 111 and a second shell 112 that cover each other. A lamp board 13 is disposed in the space formed between the first shell 111 and the second shell 112. The lamp board 13 is disposed adjacent to the second shell 112. The area on the lamp board 13 where the lamp beads (not shown) are disposed constitutes a light-emitting area 131. The portion of the second shell 112 corresponding to the light-emitting area 131 of the lamp board 13 may be transparent or hollowed out, thereby forming a light-emitting area 1121 for emitting light from the lamp beads.

[0034] The lamp body 1 also includes a heat dissipation rib 14, which is arranged on the side of the light board 13 away from the light emitting area 1121 of the second shell 112, that is, the back of the lamp board 13. The side of the lamp board 13 forming the light emitting area 131 is recorded as the front side, and the side opposite to it is the back side. When the lamp board 13 is powered on, the lamp beads thereon emit light, causing the temperature to rise. At this time, the heat dissipation rib 14 can dissipate heat from the lamp board 13. In order to enable the heat dissipation rib 14 to quickly dissipate heat to the outside of the lamp body 1 to avoid heat retention in the lamp body 1, a heat dissipation channel 15 that connects the inside and outside of the lamp body 1 is provided on the side wall of the whole formed by the first shell 111 and the second shell 112. The position of the heat dissipation channel 15 corresponds to the heat dissipation rib 14, thereby quickly dissipating heat to the outside of the lamp body 1 to avoid excessive temperature when the lamp board 13 is working. The phrase "the heat dissipation channels 15 are positioned correspondingly to the heat dissipation ribs 14" here means that the heat dissipation ribs 14 can be a plate that is closely attached to or close to the light board 13, while the heat dissipation channels 15 are located at both ends of the heat dissipation ribs 14 along their length. Because the back of the light board 13 is protected from direct water ingress, portions of the light board 13 can be exposed through the heat dissipation channels 15, directly dissipating heat from the light board 13. This improves heat dissipation and allows the first housing 111 and the second housing 112 to be made of plastic, further reducing costs.

[0035] In this embodiment, the cover 2 is a soft light cover, which is at least arranged outside the light-emitting area 131 of the lamp board 13. Here, "arranged outside the light-emitting area 131 of the lamp board 13" means covering the light-emitting area of ​​the lamp board 13 so that the light emitted by the lamp board 13 first passes through the cover 2 and radiates outward. In this embodiment, since the second shell 112 is arranged on the light-emitting path of the lamp board 13, the cover 2 is arranged on the side of the second shell 112 facing the outside of the lamp body 1, and it at least covers the light-emitting area 1121. The cover 2 and the lamp body 1 are detachably connected, thereby achieving quick disassembly and assembly. In this embodiment, the connection between the lamp body 1 and the cover 2 is through magnetic attraction. Specifically, the cover 2 includes a cover body 21 and a first magnet 22 arranged on the cover body 21. A second magnet 16 is arranged inside the lamp body 1, such as to fix the inner side of the second shell 112 facing the inside of the lamp body 1. A mounting plate 17 can also be separately provided inside the first shell 111 and the second shell 112 to mount the second magnet 16. The lamp board 13 can also be fixed to the mounting plate 17, which is located between the lamp board 13 and the second housing 112. The number and position of the first magnets 22 correspond to the second magnets 16. Preferably, the number of the first magnets 22 and the number of the second magnets 16 are both three.

[0036] The cover body 21 can be translucent, and its surface facing the inside of the lamp body 1 is smooth, while the surface facing the outside of the lamp body 1 is evenly distributed with protrusions 23, such as multi-layer annular protrusions. The protrusions 23 and the rest of the cover body 21 can be an integrally molded structure. The protrusions 23 can make the cover body 21 as a whole better play the role of softening light.

[0037] The outer cover 3 is positioned outside the housing 2, on the side away from the lamp body 1. It comprises a cover portion 31 and connecting bars 32. In this embodiment, the housing 2 is roughly disc-shaped, and the cover portion 31 is annular and fixed near the periphery of the housing 2 to avoid blocking light and facilitate securing the first magnet 22. Multiple connecting bars 32 may be provided, protruding from the side of the housing 31 away from the housing 2. "Protruding" here means that the connecting bars 32 have portions that do not contact the cover portion 31, thereby protruding relative to the surface of the housing 31. The connecting bars 32 can be arranged horizontally and vertically in a crosswise manner, which increases the strength of the cover portion 31 and protects the outer cover 3 from damage caused by collisions and falls. During installation, the housing 2 and outer cover 3 can be assembled as a single unit. The arrangement of the outer cover 3, particularly the connecting bars 32, allows the user to easily handle the housing 2. The outer cover 3 is preferably made of metal for increased strength.

[0038] Example 2

[0039] See also Figures 6 to 9 In this embodiment, the difference from the first embodiment is that the housing 2 is a lampshade, and the housing 2 and the lamp body 1 are connected by a rotating snap-fit ​​connection. The lamp body 1 uses a single lamp holder 11 instead of the separate lamp holders 11 described above. The bottom end of the lamp holder 11 is open to facilitate installation of a lamp board (not shown in the figure) into the lamp holder 11.

[0040] The cover body 2 is installed under the lamp holder 11 . The cover body 21 is roughly cylindrical with an open top. A screw button 24 extending along the circumference of the cover body 21 is formed on the outer periphery of the open end of the cover body 21 . The screw button 24 is formed with a groove 241 .

[0041] The inner wall of the lamp holder 11 is formed with a slot 113 extending along the circumference of the lamp holder 11. Positioning protrusions 114 are formed on the inner circumference of the lamp holder 11 at locations corresponding to the wall of the slot 113. Therefore, when installing the lamp body 1 and the cover 2, the open ends of the cover 2 and the open ends of the lamp holder 11 are aligned, so that the knob 24 is aligned with the slot 113. Then, by rotating the lamp body 1 and the cover 2 relative to each other, the knob 24 is engaged with the slot 113 until the positioning protrusion 114 engages with the groove 241, completing installation. To disassemble, simply rotate the knob in the opposite direction.
