Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, and specifically relates to a high-ceiling lamp. Background Technology

[0002] High-ceiling lights are fixed lighting fixtures widely used in workshops, stadiums, parking lots, large indoor gymnasiums, high-ceiling factories, supermarkets, highway toll stations, and other high-ceiling lighting locations for floodlighting. Due to the variety of applications and the different luminous efficacy requirements of various locations, the luminous efficacy requirements for lighting fixtures are diverse. Generally speaking, spotlights illuminate a small area with a high illuminance value, suitable for locations with high illuminance requirements; floodlights illuminate a wide area with a low illuminance value, suitable for general locations with lower illuminance requirements; and medium-light distribution lights illuminate a moderate area with a moderate illuminance value.

[0003] Existing high-ceiling lights are generally installed and fixed according to the needs of the site by adjusting the angle as required. However, if the angle of the high-ceiling light needs to be changed, it needs to be removed from the high place and then reinstalled and fixed. Generally, high-ceiling lights are relatively large and heavy, which can easily cause injury to workers during installation and disassembly, and the efficiency is relatively low. Summary of the Invention

[0004] I. Technical problems to be solved This utility model addresses the aforementioned deficiencies in existing technologies by proposing a high-domed lamp. Users can rotate the lampshade to change the relative positions of the lens and LED beads, thereby altering the path of light through the lens and adjusting the illumination angle to meet lighting needs in different scenarios and improve the utilization rate of the lamp.

[0005] II. Technical Solution To solve the above-mentioned technical problems, this utility model provides a high-domed lamp, including a lamp holder and a lampshade mounted on the lamp holder. The lamp holder contains equidistantly distributed LED beads in a vortex pattern. The lampshade is provided with a vortex-shaped lens corresponding to the LED beads. The lens has a semi-circular cross-section. The lampshade is rotatably mounted on the lamp holder. The lamp holder is provided with an adjusting component. The side wall of the lampshade is provided with a limiting part. By rotating the lampshade to different positions, the adjusting component and the limiting part are limited, so that the lampshade is limited between itself and the lamp holder after being rotated to different angles. Correspondingly, the position of the LED beads relative to the lens is offset to adjust the light emission angle.

[0006] Preferably, the lamp holder has a protruding edge forming a mounting frame, and the lampshade is rotatably mounted in the mounting frame. The mounting frame has a through hole. The limiting part includes a sliding guide rail disposed on the side wall of the lampshade and a limiting groove disposed in the sliding guide rail. The adjusting member includes an elastic member and a pin. Both the elastic member and the pin are mounted in the through hole. The elastic member is used to press the pin to extend into the sliding guide rail, and one end of the pin extending into the sliding guide rail is used to cooperate with the limiting groove to achieve limiting.

[0007] Specifically, the elastic element is a spring.

[0008] Preferably, one end of the ejector pin extending into the sliding guide rail is a hemispherical structure, and the other end of the ejector pin is an abutment block, the diameter of which is larger than the diameter of the hemispherical structure; a limiting platform is provided in the through hole, and the limiting platform abuts against the abutment block.

[0009] Preferably, the adjusting member further includes a screw, and the through hole has an internal thread on the side away from the lamp cover. The screw is installed in the through hole through the internal thread to limit the elastic member.

[0010] Specifically, one end of the spring abuts against the screw, and the other end of the spring abuts against the ejector pin.

[0011] Preferably, one end of the ejector pin extending into the sliding guide rail has a hemispherical structure, and a transition guide surface is provided between the limiting groove and the bottom surface of the sliding guide rail, so that the ejector pin can enter the limiting groove through the transition guide surface.

[0012] Specifically, the limiting groove is a hollow trapezoidal structure, with the larger diameter end of the trapezoid being open and connected to the bottom surface of the sliding guide rail via a transition guide surface.

[0013] Preferably, the sliding guide rail is inclined.

[0014] Preferably, multiple limiting grooves are provided, and the multiple limiting grooves are arranged along the inclined direction of the sliding guide rail.

[0015] Specifically, in this embodiment, three limiting grooves are provided, which are spaced apart within the sliding guide rail. The angles corresponding to the three limiting grooves are 60°, 90°, and 110°, respectively.

[0016] Preferably, an angle mark is provided at the edge of the lampshade, directly opposite the limiting groove, and the value of the angle mark corresponds to the angle of the lampshade when the adjusting member and the limiting groove at that position are engaged.

[0017] Preferably, four adjusting members are evenly spaced along the circumferential direction of the lamp holder, and the number and position of the limiting parts are matched accordingly.

[0018] III. Beneficial Effects 1. Compared with the prior art, the lampshade with lens installed in this utility model is rotatably connected to the lamp holder. The lampshade and the lamp holder are limited by the cooperation between the adjusting part and the limiting part. When the lampshade is rotated to different positions, the adjusting part and the limiting part achieve the limiting, so that the lampshade is limited with the lamp holder after rotating to different angles. Correspondingly, the position of the lamp bead relative to the lens is offset to adjust the light emission angle, thereby changing the path of the light through the lens and adjusting the illumination angle of the light, so as to meet the lighting needs in different scenarios and improve the utilization rate of the lamp.

[0019] 2. Compared with the prior art, in this utility model, the elastic element presses against the ejector pin, so that the ejector pin can be locked in the limiting groove, thereby achieving the limiting between the lamp cover and the lamp holder; the sliding guide rail has a guiding function. When the lamp cover is rotated, the sliding guide rail is used to limit the movement trajectory of the ejector pin, so as to prevent the ejector pin from moving to other positions and missing the limiting groove.

[0020] 3. Compared with the prior art, the transition guide surface and the hollow frustum-shaped limiting groove in this utility model cooperate to facilitate the quick engagement of the ejector pin with the limiting groove, which helps to limit the lampshade relative to the lamp holder; on the other hand, when the lampshade is rotated, the ejector pin can smoothly slide out of the limiting groove from the transition guide surface, and the lampshade can still be rotated by continuing to rotate it to adjust the angle. The structure is simple and the operation is convenient. Attached Figure Description

[0026] like Figures 1-5 As shown, a high-domed lamp includes a lamp holder 1 and a lampshade 2 mounted on the lamp holder 1. The lamp holder 1 contains LED beads evenly distributed in a vortex pattern. The lampshade 2 is provided with a vortex-shaped lens 3 corresponding to the LED beads. The lens 3 has a semi-circular cross-section. The lampshade 2 is rotatably mounted on the lamp holder 1. The lamp holder 1 is provided with an adjusting member 4. The side wall of the lampshade 2 is provided with a limiting part 5. By rotating the lampshade 2 to different positions, the adjusting member 4 and the limiting part 5 are limited, so that the lampshade 2 is limited between itself and the lamp holder 1 after being rotated to different angles.

[0027] Specifically, the lamp holder 1 integrates a power module and an electronic control unit, providing a stable power supply for the LED beads and potentially including intelligent control functions such as dimming and color temperature adjustment to adapt to lighting needs in different scenarios. The LED beads are arranged in a spiral pattern at equal intervals on the lamp holder 1, achieving a more uniform light distribution, reducing shadow areas, and improving lighting quality.

[0028] In this embodiment, the lampshade 2, on which the lens 3 is mounted, is rotatably connected to the lamp holder 1. The lampshade 2 and the lamp holder 1 are limited by the mutual cooperation between the adjusting member 4 and the limiting part 5. When the lampshade 2 is rotated to different positions, the adjusting member 4 and the limiting part 5 achieve the limiting, so that the lampshade 2 is limited between itself and the lamp holder 1 after rotating to different angles. Correspondingly, the position of the lamp bead relative to the lens 3 is offset to adjust the light emission angle, thereby changing the path of the light through the lens and adjusting the illumination angle of the light, thus meeting the lighting needs in different scenarios and improving the utilization rate of the lamp.

[0029] Preferably, the lamp holder 1 has a protruding mounting frame 11, and the lamp cover 2 is rotatably mounted in the mounting frame 11. The mounting frame 11 has a through hole 12. The limiting part 5 includes a sliding guide rail 51 disposed on the side wall of the lamp cover 2 and a limiting groove 52 disposed in the sliding guide rail 51. The adjusting member 4 includes an elastic member 41 and a pin 42. The elastic member 41 and the pin 42 are both installed in the through hole 12. The elastic member 41 is used to press the pin 42 into the sliding guide rail 51, and one end of the pin 42 extending into the sliding guide rail 51 is used to cooperate with the limiting groove 52 to achieve limiting.

[0030] Specifically, the elastic element 41 is a spring.

[0031] In this embodiment, the elastic member 41 presses against the ejector pin 42, allowing the ejector pin 42 to engage within the limiting groove 52, thus limiting the distance between the lampshade 2 and the lamp holder 1. The sliding guide rail 51 has a guiding function; when the lampshade 2 is rotated, the sliding guide rail 51 restricts the movement trajectory of the ejector pin 42, preventing the ejector pin 42 from moving to other positions and missing the limiting groove 52.

[0032] Preferably, one end of the ejector pin 42 extending into the sliding guide rail 51 is a hemispherical structure 44, and the other end of the ejector pin 42 is an abutment block 45, the diameter of the abutment block 45 being larger than the diameter of the hemispherical structure 44; a limiting platform 13 is provided in the through hole 12, and the limiting platform 13 abuts against the abutment block 45.

[0033] In this embodiment, the abutment block 45 and the limiting platform 13 are provided to prevent the ejector pin from falling out of the through hole 12, so as to ensure the stability of the ejector pin 42 when it moves in the sliding track 51.

[0034] Preferably, the adjusting member 4 further includes a screw 43, and the through hole 12 is provided with an internal thread on the side away from the lamp cover 2. The screw 43 is installed in the through hole 12 through the internal thread to limit the elastic member 41.

[0035] Specifically, one end of the spring abuts against the screw 43, and the other end of the spring abuts against the ejector pin 42.

[0036] In this embodiment, the screw 43 is provided to facilitate user disassembly and assembly when replacing parts.

[0037] In other embodiments, a limiting block may be integrally formed within the through hole 12, such that one end of the spring abuts against the limiting block, and the other end of the spring abuts against the ejector pin 42.

[0038] Preferably, the end of the ejector pin 42 extending into the sliding guide rail 51 is a hemispherical structure, and a transition guide surface 53 is provided between the limiting groove 52 and the bottom surface of the sliding guide rail 51, so that the ejector pin 42 can enter the limiting groove 52 through the transition guide surface 53.

[0039] Specifically, the limiting groove 52 is a hollow trapezoidal structure, with the larger diameter end of the trapezoid being open and this end connecting to the bottom surface of the sliding guide rail 51 through the transition guide surface 53.

[0040] In this embodiment, the transition guide surface 53 and the hollow frustum-shaped limiting groove 52 cooperate to facilitate the quick engagement of the ejector pin 42 with the limiting groove 52, which helps to limit the lampshade 2 relative to the lamp holder 1. On the other hand, when the lampshade 2 is rotated, the ejector pin 42 can smoothly slide out of the limiting groove 52 from the transition guide surface 53. Continuing to rotate the lampshade 2 with force can still rotate the lampshade 2 for angle adjustment. The structure is simple and the operation is convenient.

[0041] Preferably, the sliding guide rail 51 is inclined.

[0042] In this embodiment, the sliding guide rail 51 is inclined so that the lamp holder 1 can drive the lens 3 to adjust the tilt angle.

[0043] Preferably, multiple limiting grooves 52 are provided, and the multiple limiting grooves 52 are arranged along the inclined direction of the sliding guide rail 51.

[0044] Specifically, in this utility model, three limiting grooves 52 are provided, and the three limiting grooves 52 are spaced apart in the sliding guide rail 51. The angles of the three limiting grooves 52 are 60°, 90° and 110° respectively.

[0045] In this embodiment, the arrangement of multiple limiting grooves 52 enables the lamp holder 1 to be adjusted at multiple angles.

[0046] Preferably, an angle mark 20 is provided at the edge of the lampshade 2, directly opposite the limiting groove 52, and the value of the angle mark 20 corresponds to the angle of the lampshade 2 when the adjusting member 4 and the limiting groove 52 at that position are engaged.

[0047] In this embodiment, the setting of the angle mark 20 makes it easy for the user to quickly and conveniently adjust the lampshade 2 with the lens 3 to the required angle.

[0048] Preferably, four adjusting members 4 are evenly spaced along the circumferential direction of the lamp holder 1, and the number and position of the limiting parts 5 are matched accordingly.

[0049] In this embodiment, four of the adjusting members 4 and four of the limiting parts 5 are provided. This is beneficial for the lampshade 2 to rotate smoothly when the user adjusts the angle, avoiding the problem of unstable rotation that could damage the lamp.

[0050] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
