Background technique

LED floodlights are also known as LED spotlights and LED projection lights. LED floodlights are mainly used in single buildings, exterior wall night scene lighting of historical buildings, interior and exterior lighting of buildings, indoor partial lighting, green landscape lighting, billboard lighting, medical culture and other special facility lighting, bars, dance halls and other entertainment Mood lighting for venues. Through the control of the built-in microchip, the LED floodlight can perform long-distance and large-area projection. Generally, it is capable of aiming in any direction and has a structure that is not affected by climatic conditions. It is mainly used for large-area operation sites, mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. The floodlights are bright in color, good in monochromaticity, soft in light, low in power, and long in life, with a luminous time of up to 50,000 hours. Moreover, its LED floodlight has a compact body, is easy to hide or install, is not easy to damage, has no heat radiation, is beneficial to protect the illuminated object, and has a wide range of applications. The angle adjustment of the existing LED floodlights is inconvenient.

The sliders are all clamped, and the right end of the sliders is provided with a top block, and the opposite side of the two top blocks to the arc-shaped slider is provided with a rubber pad in contact with the arc-shaped slider. There is a fixed rod at the front and back, the fixed rod on the two sliders is connected by a tension spring, a fixed plate is arranged in the chute between the two sliders, and a rotating rod perpendicular to it is arranged on the fixed board, and the rotating rod is hinged with the fixed board An elliptical running wheel is fixedly arranged on the rotating rod between the two sliders.

Specifically, the surface of the top block opposite to the arc-shaped slider is an arc-shaped surface.

Specifically, the rotating rod is coaxial with the elliptical rotating wheel.

Specifically, a handle is provided at the left end of the rotating rod.

Specifically, the back of the LED floodlight body is provided with a plurality of cooling fins.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model has the advantages of simple structure and convenient operation, and can conveniently adjust the irradiation angle of the LED floodlight, and at the same time, the adjustment is convenient and the structure is stable.

Detailed ways

As shown in FIGS. 1-4 , an angle-adjustable LED floodlight includes a LED floodlight body 1 , and a plurality of cooling fins 4 are arranged on the back of the LED floodlight body 1 . The LED floodlight body 1 is provided with an inverted C-shaped bracket 2, the left and right ends of the bracket 2 are hinged with the left and right sides of the LED floodlight body 1 through a rotating shaft 15, and the left side of the LED floodlight body 1 An arc-shaped slider 3 coaxial with the rotating shaft 15 is fixedly arranged on the top, and a vertical chute 5 is arranged on the left side of the bracket 2, and sliders are clamped in the chute 5 on the upper and lower sides of the arc-shaped slider 3 6. The right end of the slider 6 is provided with a top block 9, and the surface of the top block 9 opposite to the arc-shaped slider 3 is an arc-shaped surface. The opposite sides of the two top blocks 9 and the arc-shaped slider 3 are provided with rubber pads 10 in contact with the arc-shaped slider 3, and a fixed rod 8 is arranged on the left end surface of the slider 6. On the two sliders 6 The fixed rod 8 is connected by a tension spring 7, a fixed plate 11 is arranged in the chute 5 between the two sliders 6, a rotating rod 13 perpendicular to it is arranged on the fixed plate 11, and a handle is arranged on the left end of the rotating rod 13. rod 14. The rotating rod 13 is hingedly connected with the fixed plate 11, and the rotating rod 13 between the two sliders 6 is fixedly provided with an oval runner 12, and the rotating rod 13 and the oval runner 12 are coaxial.

When adjusting the angle of an angle-adjustable LED floodlight, the rotating rod 13 is rotated by the turning handle 14 to make the oval running wheel 12 rotate.
