Description

Technical Field

[0001] The utility model belongs to the technical field of lamp holders, and in particular relates to an angle-adjustable rotating lamp holder. Background Art

[0002] The light bulb is connected to the lamp holder through the lamp head thread. The existing lamp holder is generally a fixed lamp holder. After the lamp holder is fixed in the specified position, the angle of the light bulb remains fixed with the fixed lamp holder. Generally, there is no need to rotate the light bulb, because ordinary light bulbs only provide lighting, and the lighting effect is the same at all angles. The atmosphere light that uses light strips to form letters, patterns, etc. is different from ordinary light bulbs. In addition to playing a certain lighting role, it plays a more atmospheric role. The letters, patterns, etc. after this kind of light bulb is lit require a specific display angle. It is difficult to achieve a suitable display angle by rotating it and threading it on an ordinary lamp holder. Rotating the light bulb to a suitable display angle relative to the lamp holder is likely to cause poor contact between the light bulb and the lamp holder, affecting the service life of the light bulb. Therefore, it is necessary to design a special lamp holder for the use of such light bulbs. Utility Model Content
