1. Field of the Invention
The present utility model relates to the LED lighting field, and more specifically to an LED ceiling lamp.
2. Description of the Related Art
Ceiling lamps are a type of light fixture installed on the ceiling inside a room or a corridor and in close proximity to its ceiling with the bottom surface fully affixed to the roof during installation. Ceiling lamps, featuring concise structure and quick installation, are broadly applied in corridors, bedrooms, toilets and other places of homes and office sites, hospitals, schools, and hotels. The light sources of the ceiling lamps in the prior art include general incandescent bulbs, fluorescent lights and LED lights, etc. In particular, LED lights are widely used in ceiling lamps due to the advantages such as reduced cost, excellent light effect, low energy consumption, and long service life.
However, a majority of ceiling lamps currently realize luminance uniformity by relying on the front giving light through the LED lamp beads arranged on the lamp panel in the shape of a circle or a matrix. LED lamp beads generally send out light at a lighting angle of 120°. Because dark regions may be formed as a result of the relative arrangement relation of LED lamp beads on the lamp panel or blocking and absorption of other structures, a series of problems may appear, for example: weakened lighting effect, nonuniform luminescence, and less attractive look.
Therefore, based on the problems above, it is necessary to provide an LED ceiling lamp which can solve the technical problems such as how to let LED ceiling lamps realize high luminance uniformity, how to reduce the formation of dark regions, and how to simplify the structure of LED ceiling lamps. Moreover, the present utility model can also solve the problems of how to realize automatic assembly of LED ceiling lamps and how to improve the heat dissipation effect of LED ceiling lamps, etc.
An LED ceiling lamp, comprising: a base; a lampshade, permanently connected with the base to form an enclosed space; an LED assembly, accommodated in the enclosed space formed by the lampshade and the base, including a lamp panel and several LED lamp beads, wherein the side of the lamp panel away from the LED lamp beads is fixed on the base; a protective cover, including a cover body and several lenses arranged in the cover body, wherein the cover body is arranged on the lamp panel and connected with the base, and lens shades are arranged onto the LED beads with each lens corresponding to one LED lamp bead.
In one of the embodiments, openings are made along the edge of the lamp panel, hold-down blocks for matching the openings are arranged on the base, and the lamp panel is affixed to the base through the openings and the hold-down blocks.
In one of the embodiments, several protruding cylinders are arranged on the cover body of the protective cover, several sticking holes are made on the corresponding positions of the base, and the protruding cylinders are fixed in the sticking holes.
In one of the embodiments, the lens is made with a concave cavity in which at least part of an LED lamp bead is accommodated.
In one of the embodiments, a terminal is also included, the output of which is electrically connected with the lamp panel and the input is intended for electrical connection with the external power supply.
In one of the embodiments, a through-hole is made in the lamp panel so that the terminal is inserted through the through-hole and fixed to the lamp panel.
In one of the embodiments, the lamp panel is round in shape.
In one of the embodiments, several LED lamp beads are evenly distributed along the perimeter of the lamp panel.
In one of the embodiments, the cover body and the lens are integrally formed.
For the LED ceiling lamp above, since the light from the LED lamp beads is refracted by the lens shades arranged on the LED lamp beads, better light distribution and uniform luminance can be achieved, making the light more uniform and softer and producing fewer dark regions.
Moreover, since the lamp panel is affixed to the base though the hold-down blocks and the openings and the protective cover are fixed to the base though the sticking holes and the protruding cylinders, this makes the installation of the LED ceiling lamp simple and free from screws so as to realize an automatic assembly process, substantially raising the assembly efficiency of LED ceiling lamps.
In addition, the heat generated by the LED assembly can be effectively dissipated to the outside through the base by affixing the lamp panel on the base; besides, no heat sink is required, reducing the complexity of the structure and the production cost of LED ceiling lamps and providing a more attractive look.
Additional aspects and/or advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
These and/or other aspects and advantages of the invention will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
The embodiments of the present utility model will be detailed hereinafter with the accompanying figures to make the aims, features, and advantages of the present utility model above more apparent. Many details are given in the following description for full understanding of the present utility model. However, the present utility model can be implemented by embodiments other than what is described herein. Those skilled in the field can make similar modifications without departing from the connotation of the present utility model. Therefore, the present utility model is not subject to the limitation of the embodiments disclosed below.
It is important to explain that when an element is described to be “fixed” to another element, it can be directly on another element or there can be one centered element. When one element is described as being “connected” with another element, it can be directly connected with another element or there can be a centered element. Expressions of the nomenclature such as “Vertical”, “Horizontal”, “Left” and “Right” used herein are only for description and do not indicate a unique embodiment.
Unless otherwise defined, all technical and scientific terms used herein have the same meaning with what those skilled in the technical field of the present utility model generally accepted. The terms used herein for the specification of the present utility model are only for describing the embodiments, but not intended to limit the present utility model. The term “and/or” used herein includes any and all combinations of one or more relevant items listed.
The present utility model provides an LED ceiling lamp, comprising: a base, a lampshade, an LED assembly and a protective cover, wherein the lampshade is permanently connected with the base to form an enclosed space, the LED assembly and the protective cover are accommodated in the enclosed space formed by the lampshade and the base; the LED assembly includes a lamp panel and several LED lamp beads arranged on the lamp panel, and the side of the lamp panel away from the LED lamp beads is fixed on the base; the protective cover includes a cover body and several lenses arranged in the cover body, wherein the cover body is arranged on the lamp panel and connected with the base, and lens shades are arranged onto the LED beads with each lens corresponding to one LED lamp bead.
