[0002] The fluorescent-free dual-color LED lamp for outdoor environment care is a special LED lighting device designed for outdoor environments to provide safe and efficient lighting while meeting specific care needs. It is particularly suitable for outdoor environments such as parks, gardens, courtyards, roads, etc. The LED lamp can emit two different colors of light, which can be adjusted as needed. This dual-color design makes the LED lamp more flexible and can meet the needs of a variety of application scenarios;

However, when actually used in outdoor environments, the application environment of lighting is more varied. Often, a single light source needs to be suitable for large-area lighting while also being able to concentrate light in a smaller area to produce a stronger light intensity. A light source with fixed lamp beads cannot switch between scattering and focusing. Utility Model Content

When the connecting rod ring frame 4 is expanded or contracted, the guide slider 7 slides in the reducing guide groove 102 and changes accordingly, while providing axial positioning for the connecting rod ring frame 4 to prevent it from torsional deformation during expansion or contraction.

[0025] Preferably, the main body of the reducing turntable 10 is in the shape of a T-shaped truncated cone, and a penetrating connecting hole is arranged in the center of the reducing turntable 10T table. The connecting hole of the reducing turntable 10 is fixedly sleeved on the output shaft of the silent motor 6, and a circular shaft-shaped connecting shaft is eccentrically arranged on the upper surface of the reducing turntable 10T table. The reducing pull rod 11 is a strip body with circular holes at both ends. One end of the reducing pull rod 11 is rotatably sleeved on the connecting shaft, and the other end of the reducing pull rod 11 is rotatably sleeved on the outer wall of the LED lamp head 9 on the connecting rod ring frame 4.

When the reducing turntable 10 rotates, the center distance between the LED lamp head 9 connected to the top of the reducing pull rod 11 and the reducing turntable 10 will switch with the rotation angle. When the LED lamp head 9 is close to the reducing turntable 10, the connecting rod ring frame 4 is pulled inward and contracted.

[0028] When the utility model is used, the connecting rod ring frame 4 is a parallelogram connecting rod ring composed of multiple connecting rod bars 41. An LED lamp head 9 is rotatably penetrated on the inner shaft hole of the parallelogram connecting rod ring of the connecting rod ring frame 4. The LED lamp head 9 is a silicon-based yellow light LED and a red light LED, which are distributed in an alternating manner. The LED lamp head 9 and the silent motor 6 are connected to the control board 5 through internal circuits. When the connecting rod ring frame 4 is scaled, the spacing between the LED lamp heads 9 is changed synchronously, so that the light source can be switched between scattering and focusing. The control board 5 is used to control the start and stop of the lamp beads inside the LED lamp head 9, so that the light source can be switched between monochrome and two-color.

[0029] When the utility model is used, when it is needed to be applicable to large-area lighting, the silent motor 6 rotates, and the silent motor 6 pulls the connecting rod ring frame 4 to expand outward through the reducing pull rod 11 with the assistance of the guide slider 7, and the spacing between the LED lamp heads 9 that are rotatably inserted through the inner shaft hole of the connecting rod ring frame 4 is increased, resulting in a wider illumination radius, making the light more evenly distributed. When it is necessary to concentrate the light in a smaller area, the silent motor 6 pulls the connecting rod ring frame 4 to contract inward through the reducing pull rod 11 with the assistance of the guide slider 7, and the spacing between the LED lamp heads 9 that are rotatably inserted through the inner shaft hole of the connecting rod ring frame 4 is reduced, resulting in a smaller illumination radius, making the light brightness and penetration higher.
