Description

Technical Field

[0001] This application belongs to the field of lighting equipment technology, and in particular relates to a lamp. Background Technology

[0002] Currently, lighting fixtures consist of a lamp holder and a driver. The driver is mounted on the back of the lamp holder, meaning it's externally mounted. Therefore, when electrically connecting the driver to the LED light source in the lamp holder, wiring must be laid between them. This results in each wire having a section exposed, making them prone to aging from sun and rain. Furthermore, the exposed wires affect the overall appearance of the lighting fixture, especially for high-power fixtures where the number of wires between the driver and lamp holder is even greater, creating a messy and unsightly appearance.

[0040] like Figures 1 to 5 , Figure 7 As shown, the lamp fixture of this application includes a lamp holder assembly 10 and a driving device 20. The lamp holder assembly 10 includes a metal housing 11, an LED light source 12, and a lens 13. The metal housing 11 forms an assembly space 112 with a light outlet 111. The LED light source 12 is mounted in the assembly space 112, and the lens 13 is sealed and mounted in the light outlet 111. The metal housing 11 is provided with a wiring channel 114 communicating with the assembly space 112. The driving device 20 is mounted on the back side 113 of the metal housing 11 away from the light outlet 111. The port of the wiring channel 114 communicates with the interior of the driving device 20 and is sealed to the outer wall of the driving device 20. The wire 60 that electrically connects the LED light source 12 and the driving device 20 passes through the wiring channel 114.

[0041] In the lamp provided in the embodiments of this application, the metal housing 11 of the lamp holder 10 is provided with a wire passage 114. The port of the wire passage 114 communicates with the interior of the drive device 20, and the port of the wire passage 114 is sealed to the outer wall of the drive device 20. In this way, the wires 60 that connect the drive device 20 and the LED light source 12 of the lamp holder 10 can be run through the wire passage 114, thus protecting the wires 60 from the effects of sun and rain, greatly slowing down the aging of the wires 60 and improving the overall lifespan of the lamp. Furthermore, the wires 60 run through the wire passage 114 are no longer messily exposed, making the overall appearance of the lamp simple and neat, improving its aesthetic quality.

[0042] like Figure 4 and Figure 7As shown, the wiring channel 114 includes a first channel segment 115 and a second channel segment 116 that are connected. The extension direction of the first channel segment 115 is perpendicular to the extension direction of the second channel segment 116. The first channel segment 115 is connected to the assembly space 112, and the port of the second channel segment 116 away from the first channel segment 115 is sealed to the outer wall of the drive device 20. By setting the first channel segment 115 and the second channel segment 116, a turning point is achieved, which facilitates the bending of the wire 60 within the wiring channel 114, thereby extending the wire 60 to the connector position of the LED light source 12 within the assembly space 112, thus facilitating wire threading.

[0043] like Figure 3 As shown, the first channel segment 115 is located in the edge region near one side of the back side 113, and the extension direction of the first channel segment 115 is parallel to the corresponding side of the back side 113. Correspondingly, the second channel segment 116 is also located in the edge region near one side of the back side 113. In this way, the overall wiring channel 114 is located near the edge of the back side 113, thereby avoiding other components of the lamp, avoiding assembly interference, and reasonably optimizing the spatial layout of the entire lamp.

[0044] like Figure 5 and Figure 7 As shown, the first channel segment 115 includes a first sub-segment 117 and a second sub-segment 118, which are symmetrically arranged with respect to the extension axis of the second channel segment 116. That is, when the wire 60 is threaded from the second channel segment 116 to the first channel segment 115, the wire 60 is threaded into the first sub-segment 117 and the second sub-segment 118 respectively, and then each wire 60 extends to the connector position of the LED light source 12 located on both sides of the second channel segment 116. This allows the numerous wires 60 to be divided into two groups for threading, simplifying the threading process and reducing the length of the wires 60 used to a certain extent, saving the amount of wires used and reducing costs.

[0045] In the lighting fixture of the embodiments of this application, the driving device 20 includes a base box 21, a cover 22, a driver 23, and a mounting bracket 24. The base box 21 is connected and fixed to the back side 113, and the cover 22 is closed and fixed to the base box 21 to form a receiving space 25. The driver 23 and the mounting bracket 24 are both located within the receiving space 25, and the driver 23 is fixedly connected to the base box 21 via the mounting bracket 24. Specifically, the base box 21 has a first enclosure wall 211, and the cover 22 has a second enclosure wall 221. The first enclosure wall 211 and the second enclosure wall 221 are connected to form the receiving space 25. The driving device 20 also includes a sealing ring 26, which is disposed between the first enclosure wall 211 and the second enclosure wall 221 to achieve a seal. By assembling the first enclosure wall 211 and the second enclosure wall 221 with the sealing ring 26, a sealed receiving space 25 is formed, ensuring the dustproof and waterproof capability of the driver 23. Furthermore, the base box 21 is locked to the back side 113 by multiple anti-vibration screws 212, reducing the possibility that the drive unit 20 may become loose from the lamp holder assembly 10 due to frequency vibration. The mounting bracket 24 is locked to the base box 21 by the first screw 27, and the driver 23 is locked to the mounting bracket 24 by the second screw 28.

[0046] To ensure a sealed fit between the port of the wiring channel 114 and the wiring hole 213 of the base box 21 for threading the wire 60, Figure 4 and Figure 5 As shown, the luminaire also includes a sealing ring 30, which seals the port of the wiring channel 114 and the wiring hole 213. Specifically, the sealing ring 30 is clamped and fixed between the port of the second channel segment 116 and the outer wall of the wiring hole 213 of the base box 21 of the drive device 20, so as to form a seal between the port of the second channel segment 116 and the outer wall of the wiring hole 213 of the base box 21 of the drive device 20.

[0047] There are two wire-threading channels 114, which are respectively located on the edge areas of opposite sides of the back side 113. Furthermore, two first channel segments 115 are located on either side of the arrangement direction of the two second channel segments 116. This further divides the numerous wires 60 into four groups for threading, simplifying the threading process and reducing the length of the wires 60 used, thus saving on the amount of wires used and lowering costs.

[0048] During the illumination process, the LED light source 12 generates heat. To dissipate this heat effectively and maintain the LED light source 12 within its normal operating range, therefore, as... Figure 1 , Figures 3 to 5As shown, the back side 113 is also provided with a plurality of spaced heat dissipation fins 119. The heat dissipation fins 119 extend toward the drive device 20, and the ends of the heat dissipation fins 119 toward the drive device 20 are spaced apart from the outer wall of the drive device 20. The plurality of spaced heat dissipation fins 119 increases the contact area between the back side 113 of the metal housing 11 and the air of the external environment. Furthermore, the spacing between two adjacent heat dissipation fins 119 facilitates airflow, which can remove more heat transferred to the heat dissipation fins 119, thereby improving the heat dissipation and cooling efficiency.

[0049] like Figures 1 to 4 As shown, the luminaire also includes a mounting lug 40 and a flexible mounting assembly 50. Both ends of the mounting lug 40 are configured as mounting ear plates 41, as shown. Figure 6 As shown, mounting portions 120 are provided on both side walls of the metal casing 11. Wherein, as... Figure 4 , Figures 8 to 10 As shown, the elastic mounting assembly 50 includes a positioning mounting plate 51, an elastic plate 52, and a connecting bolt 53. The positioning mounting plate 51 includes a plate body 511 and a plurality of circumferentially distributed protrusions 512 disposed on one side of the plate body 511. The elastic plate 52 includes a plate body 521 and a plurality of spring pieces 522 disposed on the circumferential edge of the plate body 521. The elastic plate 52 and the positioning mounting plate 51 are stacked between the mounting ear plate 41 and the mounting part 120. The connecting bolt 53 passes through the mounting ear plate 41, the plate body 521, and the plate body 511 in sequence and is screwed to the mounting part 120. The plurality of spring pieces 522 and the plurality of protrusions 512 engage with each other. When the lamp is subjected to external force and vibrates, the vibration energy first acts on the connection between the lug 40 and the metal housing 11. Since the mounting plate 41 of the lug 40 is mounted to the mounting part 120 of the metal housing 11 through the elastic mounting component 50, and the multiple spring pieces 522 of the elastic disc 52 are clamped and undergo elastic deformation, when the vibration energy is transmitted to the spring pieces 522, the elastic capacity of the spring pieces 522 will undergo resonant elastic deformation with the vibration energy. That is, the spring pieces 522 convert the vibration energy into their own elastic potential energy and finally into the internal energy of the spring pieces 522, thereby buffering and attenuating the vibration energy transmitted to the lamp holder 10, so that the lug 40 and the metal housing 11 always maintain a stable assembly relationship, reducing the possibility that the lamp holder 10 will fall off the lug 40 due to the vibration. The frequency vibration energy continues to be transmitted along the metal casing 11 to the driver 23. Since the driver 23 is connected to the base box 21 through multiple mounting brackets 24, when the frequency vibration energy is transmitted to the multiple mounting brackets 24, the multiple mounting brackets 24 simultaneously buffer and attenuate the frequency vibration energy, further reducing the impact of frequency vibration on the driver 23 and improving the vibration resistance of the driver 23.

[0050] Furthermore, a dust cover 54 is provided on the outer side of the mounting ear plate 41, which covers the head of the connecting bolt 53 to prevent dust from entering the head of the connecting bolt 53.

[0051] like Figure 9 As shown, the positioning mounting plate 51 also includes a positioning pin 513, which is located on the side of the plate body 511 opposite to the protruding tooth 512. Figure 6 As shown, the metal housing 11 is also provided with a positioning hole 121 that matches the positioning pin 513. The positioning pin 513 is inserted into the positioning hole 121. Under the locking action of the connecting bolt 53 and the elastic force of the multiple spring pieces 522 of the elastic disc 52, as well as the contact of the mounting ear plate 41 against the elastically deformed multiple spring pieces 522, the positioning mounting disc 51 is fixed relative to the mounting part 120. Due to the positioning assembly between the positioning pin 513 and the positioning hole 121, during the resonant elastic deformation of the spring pieces 522 with the frequency vibration energy, the possibility of relative displacement between the positioning mounting disc 51 and the mounting part 120 can be reduced, so that the lamp holder device 10 can still provide normal illumination.

[0052] Preferably, the lighting fixtures provided in the embodiments of this application are floodlights for outdoor floodlighting. In other embodiments of this application, the lighting fixtures may also be other types of lighting fixtures, such as spotlights used on indoor stages, searchlights used in outdoor open areas, etc., which are not limited here.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
