Description

Technical Field

[0001] The utility model belongs to the technical field of floodlights, in particular to an anti-glare floodlight. Background Art

[0002] Floodlights are lamps that make the illumination on the designated illuminated surface higher than that of the surrounding environment. They are also called spotlights. Usually, they can be aimed in any direction and have a structure that is not affected by climatic conditions. Floodlights have strong light and focusing characteristics, but they have the disadvantage of glare. Glare refers to the phenomenon that the light source directly or strongly reflects into the eyes, causing visual discomfort or interference. This often occurs during night driving, outdoor sports or indoor lighting.

[0003] In the process of using the floodlight, the angle of the lamp needs to be adjusted. Frequent rotation of the connection between the floodlight and the bracket will make it loose, thereby affecting the adjustment of the angle of the floodlight. Frequent maintenance is required, which is inconvenient. Therefore, we propose an anti-glare floodlight. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-glare floodlight. By setting a rotating component, when the rotation stops, the angle of the floodlight can be fixed after adjustment, and it will not become loose due to frequent rotation. This solves the problem that the angle of the lamp needs to be adjusted during the use of the floodlight, and the connection part between the floodlight and the bracket will become loose due to frequent rotation, thereby affecting the adjustment of the angle of the floodlight and requiring frequent maintenance, which is inconvenient.

When the lamp board 34 inside the floodlight needs to be repaired or replaced, the pull block 23 is pulled to drive the plug rod 24 to move downward, and the circular plate 26 is driven to move downward to squeeze the spring 1 25 to generate an upward elastic force. When the plug rod 24 is away from the limit block 21, the transparent plate 14 is flipped over, and the notch on the front side of the lamp housing 11 is opened. At this time, the lamp board 34 can be taken out for repair and replacement, and the replaced lamp board 34 is placed inside the lamp housing 11, and the transparent plate 14 is rotated to reset, and the pull block 23 is released. The elastic force generated by the spring 1 25 pushes the limit block 21 to move upward, driving the plug rod 24 to be inserted into the limit block 21, and the transparent plate 14 is fixed. The material of the transparent plate 14 is an uneven surface, which can avoid direct light while ensuring that light energy is transmitted, thereby achieving an anti-glare effect.
