Description

A rotatable LED spotlight

Technical Field

The utility model relates to the technical field of LED spotlights, in particular to a rotatable LED spotlight.

Background Art

LED spotlights are spotlights that use light-emitting diodes as light sources. Traditional spotlights mostly use halogen lamps, which have low luminous efficiency, high power consumption, increased ambient temperature, and short service life. LED light sources are far superior to traditional lighting fixtures in terms of luminous principle, energy saving, and environmental protection. LED spotlights are widely used and are often used in shopping malls, performance stages, parks and other places.

CN202691803U of the Jingjian Institute discloses a rotatable LED spotlight, including a lamp holder, a U-shaped bracket connected to the lamp holder, threaded holes on both sides of the U-shaped bracket, screws connecting the U-shaped bracket to the lamp housing to form a rotating structure in which the lamp housing rotates with the screws as the axis, the lamp housing as a whole is in a concave cylindrical shape, an arc-shaped convex groove is provided on its outer circumferential end face, a through hole is provided in the arc-shaped convex groove, a circuit board is provided in the concave surface of the lamp housing, LED lamp beads are inlaid on the circuit board, a circular heat sink is installed on the rear end face of the lamp housing, a number of heat sinks are provided in the circumferential direction of the heat sink, the end cover matches the shape of the lamp housing and the two are fixed by threaded holes provided on the end cover. The advantages of the utility model are: the rotatable LED spotlight designed by the utility model has fast heat dissipation, low cost, easy disassembly, and can be rotated in a vertical plane.

However, this patent still has some shortcomings. This type of LED spotlight does not have a height adjustment function, which makes the illumination range of the LED spotlight relatively limited. The lamp housing is connected to the U-shaped bracket by bolts, and external tools need to be carried each time for installation and disassembly, which is relatively troublesome. After long-term use, the bolts are easily rusted, making it difficult to disassemble, which is not conducive to subsequent maintenance and replacement.

To this end, we proposed a rotatable LED spotlight.
