Description

Technical Field

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

[0002] Lawn lights, as an important component of outdoor landscape lighting, are widely used in parks, courtyards, residential green spaces, scenic trails, and other scenarios. They not only provide basic lighting but also need to blend with the surrounding landscape to enhance the aesthetic appeal of the environment. Currently, the structural design of lawn lights on the market is relatively simple, usually just mounting the bulb on the lamp holder without considering waterproofing, heat dissipation, or emergency lighting functions. When used outdoors, they are easily damaged by rainwater intrusion, affecting their lifespan. At the same time, they cannot provide emergency lighting in the event of a power outage, failing to meet the lighting needs of some special scenarios. Furthermore, the installation and disassembly of the lights are not convenient, bringing certain difficulties to installation and maintenance work. Utility Model Content

In one embodiment, it includes a base 1, a support frame connected to the bottom of the base 1, a lamp post 2 installed on the top of the base 1, and a lamp holder 3 installed on the top of the lamp post 2. The bottom of the lamp holder 3 has a power supply cavity, and a power supply 32 is installed inside the power supply cavity. The top of the lamp holder 3 has a first mounting cavity 33, and the upper part of the inner wall of the first mounting cavity 33 has a mounting step 34. A lamp plate 35 connected to the power supply 32 is installed on the mounting step 34, and a plurality of LED beads are installed at the bottom of the lamp plate 35. A lens 36 covering the LED beads is also installed below the lamp plate 35. A plurality of light-transmitting holes 37 penetrating into the first mounting cavity 33 are spaced apart in the circumferential direction on the middle part of the outer wall of the lamp holder 3, and a grid 38 is installed in each light-transmitting hole 37. The bottom of the lamp holder 3 is also connected to a power supply bottom cover 4, and the top of the lamp holder 3 is also installed with a top cover 5.

The heat sink 31 can effectively dissipate the heat generated by the lamp panel 35 during operation, prevent the lamp panel 35 from overheating and affecting its performance and service life, and improve the heat dissipation performance of the lawn light; the second wire hole 341 is used for the wire to pass through, so that the wire can be connected from the power supply cavity to the lamp panel 35 to realize power supply; the second waterproof ring 51 embedded in the second mounting groove can improve the sealing performance between the upper cover 5 and the lamp holder 3, and prevent rainwater and dust from entering the lamp holder 3.

[0030] In one embodiment, the base 1 has three arc-shaped mounting slots 11 evenly spaced on the top circumference; the support frame includes three support rods 12; the support rods 12 are L-shaped, and the upper part of the L-shaped vertical end of the support rod 12 is threaded; the upper part of the L-shaped vertical end of each support rod 12 is locked into a mounting slot 11 by a nut. The base 1 has three equally spaced arc-shaped mounting slots 11 on its top circumference for mounting support rods 12. Three support rods 12 are provided to ensure the stability of the lawn light. The support frame also includes a triangular bracket connecting piece 13. The bracket connecting piece 13 is located below the base 1, and the L-shaped vertical ends of the three support rods 12 are connected to a corner of the bracket connecting piece 13 via nuts. The bracket connecting piece 13 connects the three support rods 12 together to form a stable triangular structure, further improving the stability of the support frame and enabling it to better support the lawn light, preventing it from shaking or tipping over during use. In addition, a wire bracket 14 is installed on the top of the base 1. The wire bracket 14 is located inside the lamp post 2, and a hook 15 is provided on its upper part.
