when the brightness of an illumination area needs to be adjusted, the adjusting bolt 705 is rotated to drive the first threaded rod 704 to rotate, so that the movable top column 702 in threaded connection with the first threaded rod 704 is driven to move in the movable bottom column 701, and then the positioning circular ring 6 is driven to move upwards integrally through the sliding connection of the connecting shaft 703 and the positioning circular ring 6, and as the positioning circular ring 6 is fixedly connected with the second adjusting baffle 501 and the third adjusting baffle 503, the second adjusting baffle 501, the third adjusting baffle 503 and the first adjusting baffle 301 are mutually blocked, the scattering of light can be reduced, the light is concentrated, the height among the first adjusting baffle 301, the second adjusting baffle 501 and the third adjusting baffle 503 is always kept consistent through the design of the bearing 4, the smaller the height of the positioning circular ring 6 is, the higher the area brightness is, and conversely the larger the area brightness is lower the illumination area is;
after long-time use, the second threaded rod 801 can be rotated to drive the movable sliding block 802 to move so as to drive the third gear 803 to move and mesh with the first gear 303, at this time, the micro motor 804 can be started to drive the first adjusting baffle 301 to rotate, and through the shape design and clockwise rotation direction of the first adjusting baffle 301, the air flow can be promoted, the heat dissipation effect is further improved, and the service life is ensured;
when the third gear 803 is meshed with the second gear 504, the micro motor 804 can drive the second adjusting mechanism 5 to integrally rotate, the second adjusting mechanism 5 can rotate to drive the positioning ring 6 to rotate, and then the connecting plate 904 and the colored plate 905 are driven to rotate by the rotation of the fourth gear 903 meshed with the positioning ring 6 by taking the connecting post 902 as the center, so that the colored plate 905 can rotate to the position right above the LED chip 102 and the positioning ring 6, and the LED chip 102 emits light with different colors, thereby increasing the ornamental value.
