[0002] LED ceiling lamps are new ceiling lamps designed and produced with highly thermally conductive aluminum alloy and patented structural technology. LED ceiling lamps are widely used in the field of commercial lighting, and are slowly penetrating into the field of home lighting. The specifications of LED ceiling lamps widely used in commercial lighting are single (one LED lamp bead, and so on), 3, 5, 7, 9, 12, 15, 18, 21, 24, 30, and 36. The power of each lamp bead is 1W and 3W. Different specifications are suitable for different places, mainly depending on the brightness required by the user, the irradiation distance, the width of the installation, etc. With the increasing application of LED in the field of lighting, there are currently two ways to focus LED lamps on the market: 1. Stretch focus; 2. Rotate focus; Generally, stretch focus is used in ceiling spotlights to obviously protrude from the ceiling, which directly affects the beauty of the ceiling, while rotary focus is mainly in a single lens, but it is difficult to achieve a combination of more than two single lenses and two or more in one lens.
