Description

LED ceiling light

The invention relates to an LED ceiling lamp, in particular to an LED ceiling lamp integrating illumination and decoration effects.

With its advantages of small size, long life, low driving voltage, fast start-up, environmental protection, anti-vibration and compression resistance, LED has been widely used in daily indoor lighting, especially in ceiling lamps. LED ceiling lights meet people's requirements for brightness and energy-saving lamps, but they can't satisfy people's requirements for aesthetics. They can't form a beautiful radial shape like a crystal lamp on the ceiling, lacking decorative effect.

In view of this, the present invention provides an LED ceiling light that integrates lighting and decorative effects.

An LED ceiling lamp comprising a main illumination device for illumination, the main illumination device comprising a lamp holder and a fixing frame fixedly connected with the lamp holder, wherein the lamp holder is fixedly mounted with a first circuit of LED illuminating particles on a side of the fixing frame The board further includes an auxiliary lighting device fixed to the side of the lamp holder facing the mounting bracket, the auxiliary lighting device comprising a second circuit board mounted with LED illuminating particles, a lens and a mirror, the lens being located on the second circuit board Upper, the second circuit board and the lens are both located in the mirror, the lens is used to split the light emitted by the LED illuminating particles from the second circuit board into a plurality of light beams, and a form is formed between the two adjacent light beams In the absence of light, the mirror is adapted to reflect the plurality of beams such that the plurality of beams are projected onto the ceiling.

The LED ceiling lamp divides the light emitted by the LED illuminating particles from the second circuit board into a plurality of light beams through the lens, so that a light-free area is formed between the adjacent light beams, thereby forming a radial light shape on the ceiling to achieve a decorative effect. .

Referring to FIG. 1 and FIG. 2 simultaneously, the LED ceiling light 10 includes a main illumination device 20 for illumination and a plurality of auxiliary illumination devices 30 for decoration, and the auxiliary illumination device 30 is fixed to the main illumination device 20.

The main illuminating device 20 includes a socket 22, a lamp cover 24 fixedly coupled to the socket 22, and a holder 26 fixedly coupled between the socket 22 and the ceiling 50. The lamp holder 22 is fixed away from the side of the holder 26 to a first circuit board (not shown) on which the LED luminescent particles are mounted. Light emitted by the LED luminescent particles is transmitted through the lamp cover 24 for illumination.

The auxiliary lighting device 30 is fixed to the lamp holder 22 on the side facing the holder 26. In the present embodiment, the auxiliary illuminating device 30 is two, and is symmetrically fixed to both sides of the fixing frame 26. Each of the auxiliary lighting devices 30 includes a second circuit board 34 on which the LED luminescent particles 32 are mounted, a lens 36, a mirror 38, and a protective cover 39. The second circuit board 34, the lens 36, the mirror 38 and the protective cover 39 can be fixed to the socket 22 by screws (not shown). The mirror 38 has a hollow cylindrical shape and is disposed facing the ceiling 50. A protective cover 39 houses the mirror 38 therein for protecting the mirror 38. The second circuit board 34 and the lens 36 are both located within the mirror 38, and the lens 36 is located above the second circuit board 34.

Referring to FIG. 2 to FIG. 4 simultaneously, the lens 36 is a multi-faceted prism including a plurality of light-emitting surfaces 360 that converge toward the light incident thereon. An end of the lens 36 adjacent to the second circuit board 34 forms a receiving groove 362 and a receiving hole 363 extending through the receiving groove 362. The accommodating groove 362 is for accommodating the second circuit board 34. The accommodating hole 363 is for accommodating the LED luminescent particles 32, and the accommodating hole 363 has a semicircular arc shape to converge light from the LED luminescent particles 32. The end of the lens 36 away from the second circuit board 34 forms a recess 364. The recess 364 is formed by combining a plurality of concave reflecting surfaces 366, which may have the same shape, the same curvature, or may have The different shapes and different curvatures are used to totally reflect the light incident from the LED illuminating particles 32 at a predetermined angle to the corresponding light-emitting surface 360, and the light is refracted through the light-emitting surface 360 to emit light, thereby achieving light convergence and light-emitting. As the angle becomes smaller, the light emitted from the LED luminescent particles 32 will be split into a plurality of beams. Thus, after the light incident on the adjacent two reflecting surfaces 366 is emitted, a matte region will be formed between the two beams.

Referring to FIG. 5 and FIG. 6 , the light from the LED illuminating particles 32 is refracted by the light emitting surface 360 and then incident on the mirror 38. The light is reflected by the mirror 38 multiple times and then projected onto the ceiling 50 to form a bright region 52. Since a light-free region is formed between the two light beams incident on the mirror 38, when the mirror 38 is reflected by the mirror 38 and projected onto the ceiling 50, the light-free region 54 is also formed. Thus, the light-emitting region 52 is formed at intervals. The light zone 54 forms a radial light shape on the ceiling 50, which brings beauty and achieves a decorative effect.
