The invention discloses a cylindrical lens annular-distributing type high-brightness ceiling lamp which comprises an aluminum substrate, a high-power LED chip, a cylindrical lens array, an inner radiating cover and an outer radiating cover. The high-power LED chip is fixed on the aluminum substrate. The aluminum substrate is fixedly connected with the inner radiating cover, a cavity for containing the cylindrical lens array is formed in a surrounding mode, and light of a light-out face of the high-power LED chip is emitted out through the cylindrical lens array. The inner radiating cover and the outer radiating cover are connected through two fixing points. The relative positions of the inner radiating cover and the outer radiating cover can be changed through the two fixing points. Light emitted through the LED chip is processed by the cylindrical lens array, then a dazzling-free parallel light source is formed, the structure is simple, assembling and disassembling are convenient, and maintaining cost is low. The inner radiating cover and the outer radiating cover can rotate relatively, accordingly the light ray irradiation angle of the ceiling lamp is adjusted, the structure is simple, and emitting angle adjusting is convenient.
Description
technical field [0001] The invention relates to the technical field of LED lighting, in particular to a cylindrical lens ring-distributed high-brightness ceiling lamp. Background technique [0002] LED ceiling lights are generally used in the fields of indoor lighting, atmosphere lighting and commercial lighting. Convenience and so on. [0003] The Chinese patent application number "201310264584.9" discloses a LED ceiling lamp. The bottom outer edge of the reflector cup of the ceiling lamp is provided with a flange, and a process edge and a plate ring are provided on the lamp circle. The bottom and diffuser plates are arranged on the process side inside the plate circle. Such a structure requires a plurality of components such as a diffusion plate, which is inconvenient to assemble and disassemble. At the same time, the light of this structure depends on the reflector, which is easy to produce glare and affect the lighting. Contents of the invention [0004] Aiming at ...
