Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lamp head structure for an LED outdoor lamp. Background Technology

[0002] As people's living standards improve, they are paying more and more attention to healthy lifestyles and are more actively engaging in outdoor activities. To create a comfortable outdoor living environment and to ensure a smooth and safe camping trip, people usually use outdoor lighting fixtures for illumination.

[0003] Current outdoor lighting fixtures consist of a lamp holder, a lamp tube, and a light bulb. The lamp tube is mounted on the lamp holder, and the light bulb is installed inside the lamp tube, with the light focused by a condenser inside the lamp tube. However, this structure has some drawbacks:

[0004] 1. The difficulty in assembling the photoconcentrator results in poor production efficiency and high production costs;

[0005] 2. Poor light-gathering efficiency affects outdoor lighting use;

[0006] 3. During the lighting process, heat is concentrated too much inside the lamp tube and cannot be dissipated quickly. Prolonged high temperature will reduce the lifespan of the LED light board.

[0007] Therefore, it is necessary to develop a lamp holder structure that can achieve quick installation, improve light focusing effect, and ensure service life. Utility Model Content

[0008] The purpose of this utility model is to provide a lamp head structure for an LED outdoor light, which solves the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A lamp holder structure for an LED outdoor light, comprising:

[0011] The lamp holder includes a lamp tube and a base and a cover respectively disposed at both ends of the lamp tube. A heat dissipation plate is disposed at one end of the lamp tube near the base, and the heat dissipation plate is connected to the base by screws.

[0012] A lighting assembly, the lighting assembly including at least an LED light-emitting board, the LED light-emitting board being fixed to the heat sink;

[0013] A focusing assembly includes a first focusing lens and a second focusing lens. The first focusing lens is mounted on the front end of the lamp tube via a cover, and the second focusing lens is mounted on the front end of the LED light-emitting panel via a lens mount. The lens mount is connected to the heat sink via screws.

[0014] Furthermore, the heat sink and the lamp tube are an integral structure and are made of aluminum alloy.

[0015] Furthermore, the lighting assembly also includes a PCB connector, the LED light-emitting board is disposed on the top surface of the heat sink, the PCB connector is disposed on the bottom surface of the heat sink, and the LED light-emitting board and the PCB connector are connected by copper pillars.

[0016] Furthermore, the cover is threaded to the outer front end of the lamp tube, and a mounting ring is provided between the first condensing lens and the lamp tube. The first condensing lens is embedded in the mounting ring, and the mounting ring is embedded in the inner front end of the lamp tube, so that the mounting ring and the first condensing lens are fixed when the cover is threaded on the lamp tube.

[0017] Furthermore, a first sealing ring is provided at the bottom of the first condensing lens, and the first sealing ring is sealed and connected to the first condensing lens and the mounting ring respectively.

[0018] Furthermore, the top of the mounting ring is provided with a groove along the circumference, and a second sealing ring is provided in the groove. The second sealing ring is sealed and connected to the cover and the mounting ring respectively.

[0040] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0041] refer to Figures 1 to 6 A lamp head structure for an LED outdoor light includes a lamp holder 100, a lighting component 200, and a focusing component 300;

[0042] The lamp holder 100 includes a lamp tube 110 and a base 120 and a cover 130 respectively disposed at both ends of the lamp tube 110. A heat sink 111 is disposed at the end of the lamp tube 110 near the base. The heat sink 111 is connected to the base 120 by screws. It should be noted that the heat sink 111 and the lamp tube 110 are integral structures and are preferably made of aluminum alloy. When the lighting assembly 200 is turned on, the heat sink 111 is heated and conducts heat to the lamp tube 110, so that the lamp tube 110 exposed to the outside helps the heat sink 111 dissipate heat, thereby increasing the service life of the lighting assembly 200.

[0043] The lighting assembly 200 includes an LED light-emitting board 210 and a PCB wiring board 220. The LED light-emitting board 210 is disposed on the top surface of the heat sink 111, and the PCB wiring board 220 is disposed on the bottom surface of the heat sink 111. The LED light-emitting board 210 and the PCB wiring board 220 are connected by copper pillars. Since the LED light-emitting board 210 is the heat-generating end, placing the LED light-emitting board 210 and the PCB wiring board 220 on opposite sides of the heat sink 111 facilitates wiring and power supply, reduces circuit load, and extends circuit life.

[0044] The focusing assembly 300 includes a first focusing lens 310 and a second focusing lens 320. The first focusing lens 310 is mounted on the front end of the lamp barrel 110 via a cover 130, and the second focusing lens 320 is mounted on the front end of the LED light-emitting panel 210 via a lens mount 330. The lens mount 330 is connected to the heat sink 111 via screws. It should be noted that the light emitted from the LED light-emitting panel 210 is first refracted and focused by the second focusing lens 320, and then the light is further refracted by the first focusing lens 310, resulting in a more concentrated light source and better lighting effect. In addition, the lens mount 330 is connected to the heat sink 111 via screws. During installation, the first focusing lens 310 is threadedly connected to the lamp barrel 110 via the cover 130, while the second focusing lens 320 is mounted on the front end of the LED light-emitting panel 210 via the lens mount 330. This structure facilitates the assembly of the lamp head, thereby improving production efficiency.

[0045] Specifically, the cover 130 is threaded to the outer front end of the lamp barrel 110, and a mounting ring 140 is provided between the first condensing lens 310 and the lamp barrel 110. The first condensing lens 310 is embedded in the mounting ring 140, and the mounting ring 140 is embedded in the inner front end of the lamp barrel 110, so that when the cover 130 is threadedly installed on the lamp barrel 110, the mounting ring 140 and the first condensing lens 310 are fixed.

[0046] Specifically, a first sealing ring 150 is provided at the bottom of the first condensing lens 310, and the first sealing ring 150 is sealed and connected to the first condensing lens 310 and the mounting ring 140 respectively; in addition, a groove 141 is provided along the top of the mounting ring 140, and a second sealing ring 160 is provided in the groove 141, and the second sealing ring 160 is sealed and connected to the cover 130 and the mounting ring 140 respectively; by providing two sealing structures on the mounting ring 140, the sealing performance is further enhanced, preventing external rainwater, dust and debris from entering the lamp tube 110.

[0047] Specifically, the heat sink 111 is provided with at least two positioning holes 112, and the base 120 is provided with positioning posts 121 corresponding to the positioning holes 112. The positioning posts 121 are inserted into the positioning holes 112. During installation, the lamp tube 110 is placed on the base 120. The positioning fit between the positioning posts 121 and the positioning holes 112 ensures that the position of the lamp tube 110 and the base 120 will not be deviated when they are connected.

[0048] Specifically, a third sealing ring 170 is provided on the top of the base 120, and the third sealing ring 170 is sealed to the base 120 and the heat sink 111 respectively; this structure is used to improve the sealing performance between the base 120 and the lamp tube 110.

[0049] Specifically, the lens mount 330 has a through groove 331 at its center, and the second condensing lens 320 is embedded in the through groove 331. The two ends of the lens mount 330 are bent downward to form connecting parts 332, and the connecting parts 332 are connected to the heat sink 111 by screws. It should be noted that a cavity is formed between the two connecting parts 332, and the cavity is used to avoid the LED light-emitting plate 210.
