LED (light emitting diode) ceiling lamp

Abstract

The invention discloses an LED (light emitting diode) ceiling lamp. The LED ceiling lamp comprises a base plate, an LED light source subassembly, a driving device and a light transmitting cover, wherein the center of the back surface of the base plate extends to form a cavity; and the driving device and a wire can be accommodated in the cavity and are not exposed, so that the light ceiling lamp is simple and attractive in appearance. The LED light source subassembly is fixedly arranged on the front surface of the cavity. Compared with the traditional fluorescent tube, the LED ceiling lamp is high in lighting effect, low in power consumption and long in service life, and is energy-saving and environment-friendly. An annular groove is formed in the front surface of the base plate and surrounds the cavity; an annular inclined plane which is inclined outwards is arranged on the front surface of the base plate; the height of the cavity is greater than that of the outer edge of the annular groove by 0.2 centimeter to 0.5 centimeter, light emitted from the LED ceiling lamp cannot be shielded by the annular groove, and dark zones do not exist. The LED ceiling lamp is wide in light emitting range, high in light using rate and high in lighting effect.

Description

technical field [0001] The invention relates to a ceiling lamp, in particular to an LED ceiling lamp. Background technique [0002] Ceiling lamp is a kind of light fixture. As the name suggests, it is called ceiling light because the top of the light fixture is relatively flat and the bottom is completely attached to the roof when installed. Ceiling lamps are widely used in various occasions such as homes, offices, and entertainment venues. The light source of existing ceiling lamps generally adopts ordinary fluorescent tubes, which have mediocre luminous effects, high power consumption, and short service life, and the internal fluorescent powder is likely to cause harm to the environment, which does not conform to the concept of energy saving and environmental protection. Moreover, parts such as the ballast or the driving device of the existing ceiling lamp are generally arranged between the front of the chassis of the ceiling lamp and the light-transmitting cover, or are ...

AI Technical Summary

Problems solved by technology

The light source of existing ceiling lamps generally adopts ordinary fluorescent tubes, which have mediocre luminous effects, high power consumption, short service life, and the internal fluorescent powder is easy to cause harm to the environment, which does not conform to the concept of energy saving and environmental protection

Moreover, parts such as the ballast or the driving device of the existing ceiling lamp are generally arranged between the front of the chassis of the ceiling lamp and the light-transmitting cover, or are exposed on the back of the chassis, and the driving device is arranged on the front of the chassis and the transparent cover. Between the mask, it is easy to block the light, resulting in a dark area of ​​light emission, a narrow light emission range, and poor light emission effect. When the driving device is installed on the back of the chassis, it will be exposed, which affects the appearance of the appearance.
