Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting fixture and an ambient light. Background Technology

[0002] Lighting fixtures generally consist of a housing, a lamp cover, a lamp panel, and wires. The housing has a cavity and a through-hole. The wires pass through the through-hole into the cavity and are electrically connected to the lamp panel. The lamp cover is placed on the housing to cover the cavity. Existing lighting fixtures on the market achieve waterproofing and dustproofing through potting and sealant at the through-hole to isolate the cavity from the external environment. However, potting sealant structures are prone to problems such as air bubbles in the glue and inadequate control of the potting process, leading to exposed components. The sealant also has the same problem, failing to guarantee complete isolation between the cavity and the external environment. Neither of these methods can achieve a good sealing effect, allowing dust and water droplets to easily enter the lighting fixture. Over time, this will affect the lighting effect and the stable power supply of the lamp panel. Utility Model Content

[0018] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please see Figures 1 to 5 This utility model discloses a lamp, which includes: 1. Base; 2. Light-transmitting cover; 3. Circuit board; 4. Multiple connecting wires. The base 1 includes a base 11 and a boss 12 extending upward from the top of the base 11. The base 1 has a receiving groove 13 that extends vertically through the boss 12 and into the base 11.

A light-emitting element 31 that is electrically connected to the circuit board 3 is disposed in the middle of the top surface of the circuit board 3. The connecting wire 4 is sequentially passed through one of the connecting holes 14a, the receiving groove 13 and another connecting hole 14b. Each connecting wire 4 includes a conductive wire 41 and an outer sheath 42 that wraps the conductive wire 41.

The outer side wall of the outer sheath 42 is fixedly connected to the inner side wall of the connecting hole 14 by integral injection molding. A light-transmitting cover 2 is placed on one end of the base 1 where a receiving groove 13 is provided. The light-transmitting cover 2 includes a flat part 21 and a side part 22. The side part 22 is formed on the side of the flat part 21 near the base 1 and extends circumferentially along the flat part 21.

A connecting protrusion 25 extending along the connecting part 23 is provided on the inner sidewall of the connecting groove 24 near the side part 22. The end of the protrusion 12 away from the base 11 is ultrasonically welded to the connecting protrusion 25 so that part of the connecting protrusion 25 flows out in a fluid manner and fills the gap between the outer sidewall of the protrusion 12 and the inner sidewall of the side part 22. The end of the protrusion 12 away from the base 11 is inserted and fixed in the connecting groove 24.

[0020] Compared with the prior art, the base 1 of this utility model has connecting holes 14 on both inner sidewalls of the receiving groove 13. The connecting wire 4 passes through one connecting hole 14a, the receiving groove 13 and the other connecting hole 14b in sequence. The light-transmitting cover 2 is placed on the base 1. A connecting part 23 is provided at the angle formed by the connection between the flat part 21 and the side part 22 of the light-transmitting cover 2. The connecting part 23 is provided with a connecting groove 24. A connecting protrusion 25 is provided on the inner sidewall of the connecting groove 24 near the side part 22. The outer sidewall of the outer sheath 42 of the connecting wire 4 is connected by an integral The injection-molded part is fixedly connected to the inner wall of the connecting hole 14 of the base 1. The boss part 12 of the base 1 and the connecting protrusion 25 of the light-transmitting cover 2 are ultrasonically welded so that part of the connecting protrusion 25 flows out in a fluid manner and fills the gap between the outer wall of the boss part 12 of the base 1 and the inner wall of the side part 22 of the light-transmitting cover 2. The end of the boss part 12 away from the base 11 is inserted and fixed in the connecting groove 24. The above structure enables the lamp to have good sealing performance, so as to achieve good dustproof and waterproof effect, which is conducive to ensuring the luminous effect and circuit stability of the lamp.

[0021] See Figures 1 to 5The material of the light-transmitting cover 2 is PC material, the material of the outer skin 42 is PVC material, and the material of the base 1 is PVC-ABS alloy material. The material of the base 1 can be ultrasonically sealed to the light-transmitting cover 2, and can also be integrally fused with the outer skin 42 of the connecting wire 4. It can also meet the requirements of the F1 material grade, which is conducive to the formation of good air tightness and adhesion after the base 1 and the outer skin 42 are integrally injection molded. At the same time, it can make the base 1 and the light-transmitting cover 2 completely fused during ultrasonic welding, effectively improving the sealing performance of the lamp.

[0022] See Figures 1 to 5 Each of the two inner sidewalls of the receiving groove 13 has a support portion 15 protruding inward. Each support portion 15 has at least one first support column 151 on its upper surface. The first support column 151 has a screw hole 152 that passes through the first support column 151 and extends vertically. Two connecting holes 14 pass through the two support portions 15 and communicate with the receiving groove 13. The end of the screw hole 152 near the support portion 15 communicates with the corresponding connecting hole 14. The bottom surface of the circuit board 3 is pressed against the first support post 151. The circuit board 3 is provided with a plurality of through-hole pads 32 that penetrate the circuit board 3 and are electrically connected to the circuit board 3. The conductive component 50 is a conductive screw 501 and multiple such screws are provided. The conductive screw 501 includes a head 51 and a screw portion 52. The screw portion 52 passes through the through hole pad 32 and is threaded into the screw hole 152. The end of the screw portion 52 away from the head 51 pierces the outer sheath 42 and is electrically connected to the corresponding conductive wire 41. The head 51 is pressed against the upper surface of the through hole pad 32 so that multiple conductive wires 41 are electrically connected to the light-emitting element 31 respectively.

[0023] The circuit board 3 is mounted to the base 1 using conductive screws 501. At the same time, the conductive screws 501 also realize the electrical connection between the through hole pad 32 of the circuit board 3 and the conductive wire 41 of the connecting wire 4, so that the connecting wire 4 can supply power to the circuit board 3 through the conductive screws 501. This structure can eliminate the original soldering operation, effectively simplify the assembly steps, improve the assembly efficiency of the lamp, and the structure of the conductive screws 501 electrically connecting the through hole pad 32 and the conductive wire 41 can improve the connection stability between the conductive wire 41 and the circuit board 3, avoid the problems of cold solder joints and false solder joints that are easy to be generated by soldering operations, and help improve the reliability and yield of the lamp.

[0024] See Figures 1 to 5 At least one edge of the head 51 is laser-welded to the upper surface of the circuit board 3, which helps the conductive screw 501 to fit firmly and tightly with the through hole pad 32 on the circuit board 3, further improving the connection stability between the conductive wire 41 and the circuit board 3.

[0025] See Figures 1 to 5Each of the two outer side walls of the base 1 corresponding to the support part 15 is provided with a limiting part 16. The connecting hole 14 passes through the limiting part 16. The setting of the limiting part 16 can increase the length of the connecting hole 14, which is conducive to further improving the airtightness and adhesion of the base 1 and the outer skin 42 after integral injection molding. At the same time, it restricts the movement of the connecting line 4 and reduces the risk of the connecting line 4 breaking.

[0026] See Figures 1 to 5 The bottom wall of the receiving groove 13 is provided with a plurality of second support columns 131 extending vertically. The second support columns 131 abut against the side of the circuit board 3 away from the light-transmitting cover 2. The end face of the second support column 131 that abuts against the circuit board 3 is at the same height as the end face of the first support column 151 that is away from the support part 15, which helps to improve the installation stability of the circuit board 3 in the receiving groove 13.

[0027] Specifically, in this embodiment, four second support columns 131 are provided and are respectively located at diagonal positions near the receiving groove 13. The inner sidewall of the receiving groove 13 is also provided with a plurality of connecting and stabilizing parts 132 protruding outward. The connecting and stabilizing parts 132 are fixedly connected to the outer sidewall of the second support column 131, but not limited thereto.

[0028] Furthermore, at least one inner sidewall of the receiving groove 13 is provided with a positioning protrusion 133, and at least one edge of the circuit board 3 is provided with a positioning opening 33 extending vertically, with the positioning protrusion 133 passing through the positioning opening 33 vertically. Specifically, in this embodiment, each inner sidewall of the receiving groove 13 is provided with a positioning protrusion 133 and is arranged on the same straight line as the two second support columns 131 in pairs. This is beneficial for the circuit board 3 to be installed into the receiving groove 13 in a specific direction so that the through hole pad 32 is accurately aligned with the screw hole 152 of the corresponding first support column 151.

[0029] See Figures 1 to 5 The lamp also includes multiple connecting screws 502 and a first communication line 401 and a second communication line 402 wrapped with an outer sheath 42. The first communication line 401 passes through one of the connecting holes 14a, and the second communication line 402 passes through the other connecting hole 14b. The circuit board 3 is also provided with a controller, which is provided with an input port and an output port. The through-hole pad 32 includes a plurality of first through-hole pads 321 electrically connected to the light-emitting element 31, a second through-hole pad 322 electrically connected to the input port, and a third through-hole pad 323 electrically connected to the output port. The first support column 151 is provided with multiple conductive screws 501 or connecting screws 502 respectively. Multiple first through-hole pads 321 are electrically connected to the corresponding conductive wires 41 through conductive screws 501. Second through-hole pads 322 are electrically connected to the first communication line 401 through connecting screws 502. Third through-hole pads 323 are electrically connected to the second communication line 402 through connecting screws 502.

[0030] Specifically, in this embodiment, each support portion 15 is provided with two first support posts 151, and two connecting lines 4 are arranged side by side, namely a positive line 4a and a negative line 4b. Two first through-hole pads 321 are provided corresponding to the positive line 4a and the negative line 4b. The positive line 4a is electrically connected to one of the first through-hole pads 321a through a conductive screw 501 connected to the first support post 151 on one of the support portions 15a. The negative line 4b is electrically connected to the other first through-hole pad 321b through a conductive screw 501 connected to the first support post 151 on the other support portion 15b. The first communication line 401 is electrically connected to the second through-hole pad 322 through a connecting screw 502 connected to the first support post 151 on one of the support portions 15a. The second communication line 402 is electrically connected to the third through-hole pad 323 through a connecting screw 502 connected to the first support post 151 on the other support portion 15b. However, this is not the only embodiment.

[0031] Specifically, in this embodiment, the controller is a control IC. The input interface and output interface of the controller are the DIN interface and DO interface of the control IC, respectively. These interfaces serve as the communication interfaces of the control IC and are used to receive data signals transmitted through the first communication line 401 and to transmit the data signals processed by the control IC to the next level of lamps through the second communication line 402, so as to realize individual control of each lamp.

[0032] Specifically, in this embodiment, the first communication line 401 and the second communication line 402 are arranged side by side with the connecting line 4 and are positioned between the two connecting lines 4. An insulating blocking block 134 is provided on the bottom wall of the receiving groove 13 between the ends of the first communication line 401 and the second communication line 402, but it is not limited to this. The structure and connection method of the connecting screw 502, the first communication line 401 and the second communication line 402 are the same as those of the aforementioned conductive screw 501 and conductive line 41, so they will not be described again.

[0033] See Figures 1 to 5 The light-transmitting cover 2 also includes a lens portion 26 that penetrates the middle of the planar portion 21. The light-emitting element 31 is disposed in the middle of the side of the circuit board 3 facing the light-transmitting cover 2, corresponding to the lens portion 26. The end face of the lens portion 26 facing the light-emitting element 31 is concave, and the end face of the lens portion 26 facing outward is convex.

[0034] The light emitted by the light-emitting element 31 is refracted by the concave inner end face of the lens 26 to achieve a mixed optical effect, and then refracted by the convex outer end face of the lens 26 to achieve a dispersed optical effect. By utilizing the above-mentioned secondary optical effect, the direction of the light emitted by the light-emitting element 31 is changed, and a certain beam emission angle is formed, which helps the light emission of the light-transmitting cover 2 to become more uniform.

[0035] See Figures 1 to 5 The light-transmitting cover 2 also includes a lens portion 26 that penetrates the middle of the flat portion 21. On the side of the flat portion 21 facing the light-emitting element 31, a plurality of pyramidal protrusions 27 are laid flat between the connecting portion 23 and the lens portion 26. These can eliminate some stray light emitted by the light-emitting element 31, thereby improving the light-emitting effect of the lamp and blurring the display of the internal circuit board 3, thus achieving the effect of beautifying the lamp.

[0036] See Figures 1 to 5 The light-transmitting cover 2 also includes a lens portion 26 that penetrates the middle of the flat portion 21. An annular concave surface 28 is provided around the lens portion 26 on the side of the flat portion 21 away from the base 1. Through the refraction of the annular concave surface 28, the light output of the light-transmitting cover 2 is more uniform, and the annular concave surface 28 can serve as an ID mark to improve the recognizability of the lamp.

[0037] Please see Figures 1 to 5 This utility model discloses an ambient light, which includes: a plurality of lamps with good sealing performance arranged at intervals as described above, and the connecting lines 4 of the adjacent lamps are connected to each other.

[0038] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
