Description

Technical Field

[0001] The utility model belongs to the technical field of lighting lamps and relates to a work lamp, in particular to a headlamp. Background Art

[0002] A headlamp is a headlight worn on the head, providing hands-free illumination. It's an essential piece of equipment for outdoor activities. Traditional work lights, most of which use flashlights, require the user to hold the light in their hand, making it inconvenient when both hands are needed. This is when a headlamp is needed. However, existing headlamps lack adjustable illumination angles, have a limited illumination range, and offer insufficient brightness, making them unsuitable for practical applications.

[0003] Upon investigation, the Chinese patent number CN202323209153.0, "A Combined Headlamp," was found to include a headband with a mounting plate at its front end; a main lamp holder, mounted at the front end of the mounting plate, with an arc-shaped support plate at its front end, and at least one transversely extending slot formed on the front face of the arc-shaped support plate; and a secondary lamp structure, selectively mounted on the arc-shaped support plate. The secondary lamp structure includes at least one secondary lamp holder slidably connected to the arc-shaped support plate, an adjustment tube at its front end, and a secondary lamp at its front end. The lighting angle of the secondary lamp can be changed by adjusting the bending angle of the adjustment tube. This headlamp is equipped with a secondary lamp to expand the lighting range, making it more convenient for nighttime use. The secondary lamp can also slide to adjust its angle. However, the structure is relatively complex, the lamp cannot be easily disassembled, and its use is not flexible. Summary of the Invention

[0019] like Figures 1 to 5 As shown, a headlamp includes a headband 6 and a lamp body A, a top band 7 is installed above the headband 6, and the lamp body A is detachably mounted on the front end of the headband 6. The lamp body A is a cylindrical structure composed of a lamp head 1, a handle part 2 and a tail sleeve 3 assembled in sequence. A lamp body mounting seat 8 is installed at the front end of the headband 6. C-shaped buckles 81 for the handle part 2 of the lamp body A to be snapped into are convexly provided on the left and right sides of the front end surface of the lamp body mounting seat 8. The lamp body A is horizontally arranged at the front end of the lamp body mounting seat 8 and is clamped in place by the C-shaped buckle 81. The lamp head 1 can rotate 360° relative to the handle part 2. The top and side of the lamp head 1 are respectively mounted with a first light-emitting element 120 and a second light-emitting element 17.

[0020] The specific structure is as follows: the lamp body mounting base 8 is a plastic part, and the lamp body mounting base 8 includes a rectangular mounting plate 82, and a C-shaped buckle 81 is protruded on the left and right sides of the front end surface of the mounting plate 82. The left and right sides of the mounting plate 82 are formed with a first buckle 83 connected to the two ends of the headband 6, and the upper end of the mounting plate 82 is formed with a second buckle 84 connected to one end of the top strap 7. One end of the top strap 7 is fixed through the second buckle 84, and the other end is placed on the headband 6. Both the headband 6 and the top strap 7 are installed with an adjustment buckle 9 for adjusting the length of the strap.

[0021] The handle portion 2 of the lamp body A is cylindrical, and a battery 5 is installed in the handle portion 2. The lamp head 1 includes a lamp head shell 11, and a lamp holder with a circuit board 1a is installed in the lamp head shell 11. The front end and side of the lamp head shell 11 are provided with mounting ports 111 and 112 for installing light-emitting elements. The first light-emitting element 120 is a high-power LED lamp bead 120 that emits white light. The LED lamp bead 120 is integrated on the LED lamp board 12 and electrically connected to the circuit board 1a. A lamp bowl 13 is provided at the front end of the LED lamp bead 120. A pressure cover 14 and a front cover 15 are provided at the front end of the lamp bowl 13 to be fixed to the mounting port 111 at the front end of the lamp head shell 11. A waterproof ring 16 is provided between the lamp bowl 13 and the pressure cover 14. The side mounting opening 112 of the lamp housing 11 is rectangular. The second light-emitting element 17 is a rectangular light panel 17 that combines white, red, and UV light. This rectangular light panel 17 is electrically connected to the circuit board 1a. A heat sink 18 is located at the side mounting opening 112 of the lamp housing 11. The rectangular light panel 17 is mounted on the heat sink 18 and secured via a rectangular transparent cover 19. This cover 19 is secured to the lamp housing 11 with an outer ring 10 and screws. A sealing ring is located between the rectangular light panel 17 and the rectangular transparent cover 19. A charging port 1b and a control switch are integrated into the circuit board 1a. A corresponding charging port and a switch button 1c are located on the other side of the lamp housing 11 corresponding to the second light-emitting element 17. The switch button 1c enables independent or combined illumination of the first light-emitting element 120 and the second light-emitting element 17, as well as switching between the white, red, and UV light modes of the second light-emitting element 17. A dust plug 1d is located at the charging port. The rear end of the lamp holder housing 11 is provided with a circular connecting sleeve 113 which is rotatably connected to the front end of the handle portion 2. The tail sleeve 3 is arranged at the rear end of the handle portion 3 through a threaded connection. The rotation of the lamp holder 1 and the installation of the tail sleeve 3 are consistent with the existing technology and will not be explained here.

[0022] An annular groove is formed between the connecting sleeve 113 of the lamp housing 11 and the lamp housing 11, and an arm clip 4 is detachably mounted in the annular groove through a C-shaped buckle 41.

[0023] When in use, the lamp body A can be clamped on the lamp body mounting base 8 and used as a headlamp, and the lamp head 1 can be rotated to adjust the lighting angle as needed, so that the headlamp can achieve better use effect. Since the lamp body 1 and the lamp body mounting base 8 are clamped and fixed by a C-shaped buckle 81, the lamp body 1 can be easily removed, which is convenient for storage and maintenance. The lamp body 1 can also be removed and held in hand for use as a flashlight alone; since the second light-emitting element 17 has white light, red light and UV light, it can be switched according to different usage needs for lighting, warning or disinfection, which greatly increases the use function of the headlamp.

[0024] At the same time, in addition to charging the battery 5, the charging port 1b can also be used to charge mobile phones, further increasing its usage functions.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
