Light emitting diode (LED) ceiling lamp

Abstract

The invention provides a light emitting diode (LED) ceiling lamp which is provided with nine condensing lenses and a surface cover which is covered on the condensing lenses, wherein the diameters of the condensing lenses range from 11.6mm to 12mm, and the diameter of the surface cover ranges from 96mm to 100mm. An inner circle distribution line and an outer circle distribution line are installed on the surface cover, three condensing lenses are evenly installed on the inner circle distribution line, and six condensing lenses are evenly distributed on the outer circle distribution line. By means of light condensation and reflection technology of transparent plastic, the diameters of the condensing lenses range from 11.6mm to 12mm, the nine condensing lenses are distributed on an inner circle and an outer circle of the surface cover through the inner circle distribution line and the outer circle distribution line of the surface cover, and therefore, the size of the surface cover is reduced. By means of adjustment of the sizes and reasonable distribution positions of the condensing lenses, the LED ceiling lamp has the small size, LED lamp beads emit light and irradiate uniformly, good illuminating effects are obtained, no light spot is produced, and cost is lowered.

Description

technical field [0001] The invention relates to the technical field of lamp lighting, and more specifically, to an LED ceiling lamp. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode) is widely used in indoor lighting, outdoor lighting and commercial lighting. 10 times, the service life can reach 50,000 hours, which is 50 times that of ordinary incandescent bulbs), the output has increased, and the price has decreased. It is a new generation of energy-saving and environmentally friendly green lighting. [0003] There are many types of LEDs, generally including ceiling lights, down lights, spotlights, track lights, buried lights, wall washers, underwater lights, light strips, etc. Among them, ceiling lights are the most widely used. There are two types of ceiling lamps: concentrating and diffusing. The structure of concentrating LED ceiling lamps currently on the market is roughly composed of lamp beads, aluminum substrates, lenses, covers, outer ...

Problems solved by technology

[0006] Moreover, when the lamp is screwed to the bottom plate during assembly, the lens, panel, and lamp beads are rotated at the same time. When screwed to the step between the panel and the inner ring, if the rotation force is not properly controlled, friction will be generated between the panel and the inner ring. It is clamped by the lamp bead and the cover. The cover does not rotate when encountering friction, but the bottom plate is still rotating, which is easy to damage the lamp bead.
