Description

Technical Field

[0001] This utility model relates to the field of outdoor lighting technology, and in particular to an outdoor lamp with adjustable color temperature. Background Technology

[0002] Outdoor lighting fixtures are lighting devices specifically designed for outdoor environments such as courtyards, roads, squares, and parks. To adapt to complex outdoor conditions, these fixtures typically need to be waterproof, resistant to high and low temperatures, and resistant to wind erosion to ensure stable operation under various environmental conditions and meet the functional and environmental lighting needs of different outdoor spaces.

[0003] However, most ordinary outdoor lighting fixtures use halogen or ordinary LED light sources with plastic covers, which generally suffer from insufficient brightness or uneven light emission, easily causing visual fatigue. At the same time, their light source color temperature is relatively uniform and cannot be adjusted according to seasonal changes or scene changes, which limits the actual application range and user experience of the lighting fixtures. Therefore, we propose an outdoor lighting fixture with adjustable color temperature to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing outdoor lighting fixtures, such as insufficient or uneven brightness that easily causes visual fatigue, and a single color temperature that cannot meet the lighting needs of different seasons and environments. Therefore, this invention proposes an outdoor lighting fixture with adjustable color temperature.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An outdoor lighting fixture with adjustable color temperature includes an end cap, an LED light fixedly mounted on the bottom of the end cap, two mounting brackets symmetrically fixedly mounted on the outer wall of the end cap, a base detachably connected between the two mounting brackets via a snap-fit ​​assembly, a light-emitting cover fitted on the LED light, and light guide ribs provided on the inner wall of the light-emitting cover. The bottom of the end cap is provided with a groove I, the top of the base is provided with a groove II, the top and bottom of the light-emitting cover are respectively inserted into groove I and groove II, and a sealing ring is provided in both groove I and groove II; The bottom of the end cap is provided with two fixing components for fixing the light-emitting cover in the groove I; A control box is fixedly installed on one side of the end cap, and a color temperature control module is installed inside the control box. The color temperature control module is electrically connected to the LED lamp.

[0006] In one possible design, the buckle assembly includes two fixing blocks II symmetrically fixedly disposed at the bottom of the base. Each fixing block II has a sliding cavity through which a fixing pin slides. Each of the two mounting brackets has a pin hole on its side that is close to each other. The two fixing pins are inserted into the corresponding pin holes. Each of the bottoms of the two fixing blocks II has a sliding opening that communicates with the corresponding sliding cavity. Each of the two sliding openings has a connecting block that slides within it. Each of the two connecting blocks is respectively sleeved on the corresponding fixing pin and fixedly connected to the fixing pin. Each of the two sliding cavities is provided with a reset mechanism.

[0007] In one possible design, the reset mechanism includes a spring II located inside the slide cavity and sleeved on a fixing pin, with both ends of the spring II abutting against one side of the inner wall of the slide cavity and one side of the connecting block, respectively.

[0008] In one possible design, the fixing component includes a fixing block I, one end of which is connected to a groove I and has a positioning hole. A positioning bead is rolled in the positioning hole. A limiting groove matching the positioning bead is radially formed on the outer wall of the light-emitting cover. When the light-emitting cover is inserted into the groove I, the positioning bead is embedded in the limiting groove. The fixing component also includes a spring I, which is located in the positioning hole and its two ends abut against the inner wall of the positioning hole and the positioning bead, respectively.

[0009] In one possible design, the outer wall of the end cap is provided with a handle.

[0010] In one possible design, three limiting rings are fixedly provided on one side of the two mounting brackets that are close to each other. The three limiting rings are all sleeved on the outer wall of the light-emitting cover and slidably connected to the light-emitting cover.

[0011] In one possible design, the bottom of the base is provided with multiple drainage holes, the bottom of the end cap is provided with a vent, and a breathable sponge is provided at the vent.

[0012] In this application, firstly, during the lamp assembly stage, the pre-installation of each component is completed; the LED lamp is securely installed at the bottom of the end cover, and two mounting brackets with limit rings are symmetrically installed on the outer wall of the end cover, while the handle is installed. Subsequently, the light-emitting cover and the end cap are connected; the top of the light-emitting cover is aligned with and inserted into the groove I at the bottom of the end cap. During this process, the outer wall of the light-emitting cover will squeeze the positioning bead in the fixing block I and compress the spring I; when the limiting groove on the light-emitting cover moves to align with the positioning bead, the spring I pushes the positioning bead into the groove, realizing the upper connection and radial limiting. At the same time, the outer wall of the light-emitting cover passes through the limiting ring on the mounting bracket to form auxiliary support. After completing the upper installation, install the base. At this time, lift the light cover assembly that is connected to the end cover, align the bottom of the light cover with the groove II of the base, and then press the connecting block in the fixing block II on the base to drive the fixing pin to compress the spring II and retract inward. Align the mating surfaces of the base and the mounting bracket, and then release the connecting block. The spring II returns to its original position and pushes the fixing pin into the pin hole of the mounting bracket to achieve quick locking at the bottom. In this step, the bottom of the light cover is also fully embedded in the groove II, and the sealing rings in the upper and lower grooves are compressed to ensure overall sealing. Once assembled, the lamp is ready for use. Operators adjust the color temperature control module via a DIP switch outside the control box. This module changes the color temperature of the LED light, and the light is diffused as it passes through the light-emitting cover with light guide ribs, creating a uniform light effect. The drainage holes in the base and the vents in the end cap work together to maintain a stable environment inside the lamp. When maintenance is required, first press the connecting block to disengage the fixing pin from the pin hole, then remove the base. Next, apply a downward force to the light cover to squeeze the positioning bead and compress spring I on the side wall of the limiting groove, thus removing the top of the light cover from the groove I. After disassembly, reassemble according to the above steps to restore the original performance.

[0013] Beneficial effects: In this utility model, the outdoor lamp with adjustable color temperature adopts a high-efficiency LED light source and is equipped with a diffused light cover with light guide ribs on the inner side. This can effectively constrain the light propagation path, reduce the loss of light energy inside the medium, and significantly improve the brightness of the light-emitting surface. At the same time, it transforms the originally concentrated beam of light into uniform and soft diffused light, eliminates local overly bright or dark areas, creates a comfortable lighting environment for human vision, and relieves the fatigue caused by looking at the lamp for a long time. In this utility model, the outdoor lamp with adjustable color temperature, through the cooperation of an external DIP switch and an internal color temperature control module, allows the operator to conveniently switch and set multiple different light source color temperature states according to the needs of actual application scenarios. This provides visually warm warm-toned lighting in cold seasons or converts to visually cool cool-toned lighting in hot seasons, greatly expanding the application range and scene adaptability of a single lamp and meeting diverse lighting needs. In this utility model, the outdoor lamp with adjustable color temperature, together with the buckle assembly set between the base and the mounting bracket and the fixing assembly at the bottom of the end cap, constitutes a detachable connection structure for the light cover. The light cover can be completely removed from the lamp body without the aid of tools, which provides convenient conditions for regular cleaning and maintenance, helps to maintain the light transmittance of optical components, and ensures stable lighting quality. In this invention, a high-efficiency LED light source is combined with a diffused light cover with light guide ribs to effectively improve the brightness of the emitted light and form uniform and soft diffused light, avoiding visual fatigue. With the linkage of an external DIP switch and a color temperature control module, the color temperature of the light source can be easily adjusted to adapt to the environmental needs of different seasons. The detachable structure composed of snap-fit ​​components and fixing components allows the light cover to be disassembled and assembled without tools, facilitating maintenance and cleaning, and ensuring a long-lasting and stable lighting effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In one embodiment: Refer to Figure 1-6An outdoor lighting fixture includes components such as an end cap 1, a mounting bracket 2, a base 3, an LED light 4, a light cover 5, a control box 6, a color temperature control module 7, a handle 8, a limit ring 9, a fixing block I 10, a positioning bead 11, a spring I 12, a fixing block II 13, a fixing pin 14, a connecting block 15, a spring II 16, a drainage hole 17, and a vent 18. The connection and cooperation methods of each component are as follows.

[0018] An LED light 4 is fixedly installed at the bottom of the end cap 1. The LED light 4 serves as the light source of the lamp and adopts a high-efficiency type to improve the basic lighting performance. Two mounting brackets 2 are symmetrically fixed on the outer wall of the end cap 1. Three limiting rings 9 are fixed on the side of the two mounting brackets 2 that are close to each other. The three limiting rings 9 are all sleeved on the outer wall of the light-emitting cover 5 and are slidably connected to the light-emitting cover 5. The limiting rings 9 provide auxiliary support for the light-emitting cover 5 and ensure the stability of the light-emitting cover 5 after installation. The outer wall of the end cap 1 is also provided with a handle 8, which allows the operator to directly lift the lamp and facilitate the relocation of the lamp during installation or transportation.

[0019] The light-emitting cover 5 adopts a diffused structure, with multiple radially spaced light-guiding ribs arranged on its inner wall. The light-guiding ribs and the light-emitting cover 5 are integrally molded by injection molding. This integral molding structure makes the light-guiding ribs also serve as structural reinforcements of the light-emitting cover 5, enhancing its structural strength. When the light emitted by the LED lamp 4 passes through the light-emitting cover 5, the light-guiding ribs effectively constrain the light propagation path, reduce the loss of light energy inside the medium, improve the brightness of the light-emitting surface, and convert the concentrated beam of light into uniform and soft diffused light, eliminating local overly bright or dark areas and avoiding eye fatigue caused by prolonged viewing.

[0020] Two fixing components for fixing the light-emitting cover 5 are symmetrically arranged at the bottom of the end cap 1. The fixing components include fixing block I10 and spring I12. One end of fixing block I10 is connected to the groove I101 opened at the bottom of the end cap 1. The fixing block I10 has a positioning hole, and a positioning bead 11 is rolled in the positioning hole. The spring I12 is located in the positioning hole, and its two ends abut against the inner wall of the positioning hole and the positioning bead 11, respectively. The outer wall of the light-emitting cover 5 has a limiting groove 501 that matches the positioning bead 11 radially. When installing the light-emitting cover 5, the top of the light-emitting cover 5 is aligned and inserted into the groove I101. During the insertion process, the outer wall of the light-emitting cover 5 squeezes the positioning bead 11, which compresses the spring I12. When the limiting groove 501 on the light-emitting cover 5 moves to align with the positioning bead 11, the spring I12 returns to its original position and pushes the positioning bead 11 into the limiting groove 501, realizing the upper connection and radial limiting of the light-emitting cover 5 and the end cap 1.

[0021] The bottom of the base 3 is provided with multiple drainage holes 17 and a vent 18. A breathable sponge is provided at the vent 18. The drainage holes 17 can drain the water that has entered the lamp in time. The vent 18, together with the breathable sponge, can realize the air circulation inside and outside the lamp, while blocking the entry of external impurities, and together maintain the stability of the internal environment of the lamp.

[0022] A control box 6 is fixedly installed on one side of the end cap 1. A color temperature control module 7 is fixedly installed inside the control box 6. A DIP switch is installed below the control box 6. The color temperature control module 7 is electrically connected to the LED lamp 4 and the DIP switch. The operator can send an adjustment signal to the color temperature control module 7 by toggling the DIP switch. After receiving the signal, the color temperature control module 7 changes the emission color temperature of the LED lamp 4, thereby switching between warm and cool light according to different seasons or environmental needs, expanding the application range and scene adaptability of the lamp.

[0023] This application can be used in the field of outdoor lighting technology, or in other fields applicable to this application.

[0024] In another embodiment: Reference Figure 3-6 An improvement based on Embodiment 1: An outdoor lighting fixture with adjustable color temperature, applied to the field of outdoor lighting technology, has a base 3 detachably connected between two mounting brackets 2 below the LED lamp 4 via a snap-fit ​​assembly. The top of the base 3 has a groove II 301, and the bottom end of the light-emitting cover 5 is inserted into the groove II 301. Both groove I 101 and groove II 301 are provided with sealing rings. When the two ends of the light-emitting cover 5 are respectively inserted into the two grooves, the sealing rings are compressed, realizing a sealed fit between the light-emitting cover 5 and the end cap 1 and the base 3. The snap-fit ​​assembly includes two fixing blocks II 13 symmetrically fixed to the bottom of the base 3. The fixing blocks II 13 are provided with sliding cavities and have fixing pins 14 sliding through them. The two mounting brackets 2 have pin holes on their adjacent sides, and the fixing pins 14 can be inserted into the corresponding pin holes. The bottom of the fixing block II 13 has a sliding opening that communicates with the sliding cavity. A connecting block 15 is slidably installed in the sliding opening. The connecting block 15 is sleeved on the fixing pin 14 and fixedly connected to the fixing pin 14. A reset mechanism is provided in the sliding cavity. The reset mechanism is a spring II 16 sleeved on the fixing pin 14. The two ends of the spring II 16 abut against one side of the inner wall of the sliding cavity and one side of the connecting block 15, respectively. When installing the base 3, pressing the connecting block 15 causes the fixing pin 14 to compress the spring II 16 and retract inward. After aligning the mating surfaces of the base 3 and the mounting bracket 2, the connecting block 15 is released. The spring II 16 resets and pushes the fixing pin 14 into the pin hole, realizing the quick locking of the base 3 and the mounting bracket 2. When disassembling, simply press the connecting block 15 again to make the fixing pin 14 exit the pin hole to separate the base 3 and the mounting bracket 2.

[0025] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
