Description

Technical Field

[0001] This utility model relates to the field of LED arc lamp technology, specifically an LED arc lamp with an adjustable illumination direction. Background Technology

[0002] A rotatable LED arc lamp with adjustable illumination direction is a specialized lighting device that combines LED lighting technology, arc lamp characteristics, and flexible steering functionality. It is primarily used in various scenarios requiring directional lighting. Using LEDs as the light-emitting element, it boasts advantages such as high efficiency, energy saving, and long lifespan. Typically composed of multiple LED beads, it emits light of specific colors and intensities, such as common red, green, blue, and orange, to meet lighting needs in different environments. The lamp can be rotated horizontally within a certain angle (within 180°) via a rotating adjustment mechanism, allowing operators to flexibly adjust the direction of the light beam for precise illumination.

[0003] Patent document CN207250457U discloses an arc lamp, which states that "the arc lamp includes an arc tube, a cylindrical protective member, and an end protective member. The cylindrical protective member surrounds the arc tube. The end protective member is disposed at at least one end of the cylindrical protective member and is spaced apart from the cylindrical protective member."

[0004] However, one of the arc beam methods mentioned in the aforementioned published documents mainly considers the problem of avoiding high-temperature fragments generated by the arc tube explosion falling on the ground or other objects, which makes it difficult for operators to intuitively determine the location of the irradiated target.

[0005] In view of this, it is necessary to develop an auxiliary positioning mechanism to help operators visually determine the position of the irradiated target and improve accuracy. Utility Model Content

[0006] The purpose of this invention is to provide an LED arc lamp with an adjustable irradiation direction, so as to solve the technical problem mentioned in the background art of enabling the LED arc lamp with an adjustable irradiation direction to have an auxiliary positioning function.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an LED arc lamp with rotatable and adjustable illumination direction, comprising: a lens cover, a PCB board, a lamp housing, an adjustment cylinder, and a mounting bracket. The outer wall of the PCB board is provided with an auxiliary positioning mechanism, which is used to assist the operator in visually determining the position of the illumination target and improving accuracy.

[0008] The auxiliary positioning mechanism includes a small laser diode lamp, a diode magnetic chuck plate is installed on the outer wall of the PCB board, a laser diode lamp is installed on the outer wall of the diode magnetic chuck plate, an interlocking groove is provided on the outer wall of the PCB board, a magnetic block is installed on the inner wall of the interlocking groove, a splicing groove is provided on the inner wall of the PCB board, a splicing stud is installed on the outer wall of the diode magnetic chuck plate, and a splicing nut is installed around the outer wall of the splicing stud.

[0009] Preferably, a lamp housing is mounted on the outer wall of the lens cover, a PCB board is mounted on the inner wall of the lamp housing, a power cord is provided on the outer wall of the lamp housing, a mounting bracket is provided at the bottom of the lamp housing, an adjusting screw is provided on the inner wall of the mounting bracket, an adjusting nut is mounted around the outer wall of the adjusting screw, an adjusting cylinder is mounted at the bottom of the lamp housing, and mounting bolts are provided on the inner wall of the mounting bracket.

[0010] Preferably, the outer wall of the mounting bracket is provided with a reflective mechanism, which is used to facilitate locating the position of the lamp.

[0011] Preferably, the reflective mechanism includes a first Velcro strap, and the outer wall of the mounting bracket is fitted with the first Velcro strap.

[0012] Preferably, the outer wall of the first Velcro is provided with a reflective strip.

[0013] Preferably, a second Velcro strap is installed on the outer wall of the reflective strip.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by installing an auxiliary positioning mechanism, assists operators in visually determining the position of the irradiated target, improving accuracy. A small laser diode is installed inside the lamp near the light source, ensuring its emitted laser point is parallel to the lamp's main irradiation direction. When adjusting the irradiation direction, the laser point serves as a reference, helping operators more intuitively determine the target position and improving adjustment efficiency and accuracy. The laser diode is controlled by a separate switch, located to the side of the LED arc lamp's control button. It is turned off when not in use to save power. The laser diode... The magnetic plate and magnetic block are attracted to each other, and one end of the splicing stud penetrates the inside of the splicing groove. Then, the splicing nut is fixed to the outside of the splicing stud. The diode magnetic plate and laser diode lamp are then installed near the light source and parallel to the irradiation direction. The laser diode lamp is then electrically connected. When the angle needs to be adjusted, the switch can be used to turn on the laser diode lamp to emit a beam of light, and the LED arc lamp also emits light. At this time, the staff can use the beam of light emitted by the laser diode lamp (not scattered, but a straight line) to determine the position of the target to be irradiated, thus improving the adjustment efficiency and accuracy.

[0016] 2. This utility model, by installing a reflective mechanism, facilitates the location of the lamp. Existing LED arc lamps cannot be located in low-light environments, making it difficult to quickly determine the initial position when adjusting the lamp angle. This invention improves upon this by first attaching the second Velcro strap to the first Velcro strap to install the reflective strip on both sides of the mounting bracket. When the LED arc lamp is not in operation and in a low-light environment, workers can use a flashlight to illuminate the lamp and determine its initial position through the reflective strip, thus facilitating the activation of the LED arc lamp and adjustment of its illumination direction.

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6An LED arc lamp with adjustable illumination direction includes: a lens cover 1, a PCB board 2, a lamp housing 3, an adjusting cylinder 8, and a mounting bracket 5. The lamp housing 3 is mounted on the outer wall of the lens cover 1, and the PCB board 2 is mounted on the inner wall of the lamp housing 3. A power cord 4 is provided on the outer wall of the lamp housing 3. The mounting bracket 5 is provided at the bottom of the lamp housing 3. An adjusting screw 6 is provided on the inner wall of the mounting bracket 5. An adjusting nut 7 is mounted around the outer wall of the adjusting screw 6. The adjusting cylinder 8 is mounted at the bottom of the lamp housing 3, and a mounting bolt 9 is provided on the inner wall of the mounting bracket 5. First, the LED arc lamp components are mounted on the PCB board 2. Then, the lamp housing 3 and the lens cover 1 are connected. Next, the adjusting cylinder 8 passes through the outside of the adjusting screw 6. Then, the LED arc lamp components are mounted on the PCB board 2. After adjusting the angle of the LED arc lamp to the appropriate position, fix the adjusting nut 7 to the outside of the adjusting screw 6. Use the two sides of the mounting bracket 5 to clamp and fix the angle of the adjusting cylinder 8, thus fixing the angle of the LED arc lamp. Then, install the arc lamp in the designated position using the mounting bolt 9. The LED arc lamp can be adjusted 180°. The control button for the LED arc lamp is located at the rear of the lamp housing 3. Adjust the angle as needed. The LED arc lamp has two models: F0428 and F0428RGB. Both F0428 and F0428RGB models have an arc beam lighting mode. The F0428 model has blue, red, orange, and green light colors. The RGB model features red, green, and blue lighting colors, with various mixed colors achieved through RGB and the combination of these four colors. Both models have a power of 16 watts and are compatible with voltages between 10 volts and 80 volts. Each lamp uses a single 16W LED and is connected via bare wire. The power cord has four 4-wire lengths and is 400 mm long. The lamps have a high protection rating to prevent dust ingress and can withstand high-temperature, high-pressure water jets. They can operate normally in temperatures ranging from -40 degrees Celsius to 80 degrees Celsius.

[0031] Please see Figure 1 , Figure 7 and Figure 8The outer wall of PCB board 2 is equipped with an auxiliary positioning mechanism to help operators visually determine the position of the irradiated target and improve accuracy. The auxiliary positioning mechanism includes a small laser diode lamp 11, a diode magnetic suction plate 10 mounted on the outer wall of PCB board 2, a laser diode lamp 11 mounted on the outer wall of the diode magnetic suction plate 10, a fitting groove 13 on the outer wall of PCB board 2, a magnetic block 14 mounted on the inner wall of the fitting groove 13, a splicing groove 15 on the inner wall of PCB board 2, a splicing stud 16 mounted on the outer wall of the diode magnetic suction plate 10, and a splicing nut 17 mounted around the outer wall of the splicing stud 16. A small laser diode lamp 11 is installed inside the lamp near the light source, so that the laser point emitted is parallel to the main irradiation direction of the lamp. When adjusting the irradiation direction, the laser point can serve as a reference, helping operators to more visually determine the position of the irradiated target and improve accuracy. With high adjustment efficiency and accuracy, the laser diode lamp 11 is controlled by a separate switch, located to the side of the LED arc lamp's control button. It is turned off when not in use to save power. First, the diode magnetic plate 10 and magnetic block 14 are magnetically attracted, with one end of the splicing stud 16 penetrating the interior of the splicing groove 15. Then, the splicing nut 17 is fixed to the outside of the splicing stud 16. The diode magnetic plate 10 and laser diode lamp 11 are then installed near the light source, parallel to the irradiation direction. The laser diode lamp 11 is then electrically connected. When angle adjustment is needed, the switch can be used to illuminate the laser diode lamp 11, emitting a beam of light. The LED arc lamp also emits light via the control button. The operator can then determine the location of the target to be irradiated by the beam emitted by the laser diode lamp 11 (a straight, non-scattered beam), thus improving adjustment efficiency and accuracy.

[0032] Please see Figure 6 and Figure 9 The outer wall of the mounting bracket 5 is equipped with a reflective mechanism to facilitate the location of the lamp. The reflective mechanism includes a first Velcro 18, which is installed on the outer wall of the mounting bracket 5. The outer wall of the first Velcro 18 is equipped with a reflective strip 20, and the outer wall of the reflective strip 20 is equipped with a second Velcro 19. In existing LED arc lamps, the location of the lamp cannot be determined in a dark environment. Therefore, when it is necessary to adjust the angle of the lamp, it is not possible to quickly determine the initial position of the lamp. This is improved by firstly attaching the second Velcro 19 and the first Velcro 18 to install the reflective strip 20 on both sides of the mounting bracket 5. When the LED arc lamp is not working and in a dark environment, the staff can use a flashlight to shine a light on it and determine the initial position of the lamp through the reflective strip 20, which facilitates the turning on of the LED arc lamp and the adjustment of the illumination direction.

[0033] The working principle is as follows: First, the LED arc lamp components are mounted on the PCB board 2. Then, the lamp housing 3 and lens cover 1 are connected. Next, the adjusting cylinder 8 passes through the outside of the adjusting screw 6. After adjusting the angle of the LED arc lamp to the appropriate position, the adjusting nut 7 is fixed to the outside of the adjusting screw 6. The angle of the adjusting cylinder 8 is fixed by clamping it on both sides of the mounting bracket 5, thus fixing the angle of the LED arc lamp. Then, the arc lamp is installed in the designated position using the mounting bolt 9. The LED arc lamp can be adjusted 180°. The control button of the LED arc lamp is located at the rear of the lamp housing 3. The angle can be adjusted as needed. The LED arc lamp has two models: F0428 and F0428RGB. Both F0428 and F0428RGB models have an arc beam lighting mode. The F0428 model has blue, red, orange, and green light colors. The RGB models offer red, green, and blue lighting colors, with various mixed colors achieved through RGB and color mixing. Both models have a power of 16 watts and operate within a voltage range of 10V to 80V. Each lamp uses a single 16W LED and features bare wire connections with a 400mm long, 4-wire power cord. The lamps have a high protection rating, preventing dust ingress and withstanding high-temperature, high-pressure water jets. They can operate normally in temperatures ranging from -40°C to 80°C. A small laser diode 11 is installed inside the lamp near the light source, aligning its laser beam with the lamp's main illumination direction. This laser beam serves as a reference when adjusting the illumination direction, helping operators more intuitively determine the target location and improving adjustment efficiency and accuracy. The laser diode 11 is controlled by a separate switch located next to the LED arc lamp's control button. It is turned off when not in use to save power. The system is first connected via a magnetic diode plate 10 and a magnetic block. 14. Magnetic attraction occurs, and one end of the splicing stud 16 penetrates the interior of the splicing groove 15. Then, the splicing nut 17 is fixed to the outside of the splicing stud 16. The diode magnetic plate 10 and the laser diode lamp 11 are then installed near the light source, parallel to the illumination direction. The laser diode lamp 11 is then electrically connected. When angle adjustment is needed, a switch can be used to illuminate the laser diode lamp 11, emitting a beam of light, and the LED arc lamp also emits light. At this time, the worker can determine the location of the target to be illuminated by the beam emitted by the laser diode lamp 11 (a straight, non-scattered beam), improving adjustment efficiency and accuracy. Existing LED arc lamps cannot determine the lamp's position in dark environments, making it difficult to quickly determine the initial position when adjusting the lamp's angle. To address this, the second Velcro 19 and the first Velcro 18 are used to attach the reflector strip 20 to both sides of the mounting bracket 5. When the LED arc lamp is not working and in a dark environment, the worker can use a flashlight to illuminate it.The initial position of the lamp can be determined by the reflective strip 20, which facilitates the activation of the LED arc lamp and the adjustment of its illumination direction.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
