Embodiment Construction

[0019] Refer to the attached figure 1 to attach Figure 7 Combined with preferred embodiments of the present invention, it will be further described in detail. In addition, the same part is represented by the same symbol to avoid repeated description.

[0020] According to attached figure 1 It means that the LED ceiling lamp is mainly composed of a lampshade (10), a driving cover (40), a driving module (50), a light source cover (60), a light source module (70), and a chassis (80). During the installation process of the LED ceiling lamp, the lampshade (10) is screwed to the chassis (80) to form a cavity, and the driving cover (40) and the driving module (50) are arranged in the cavity and fixed together on the chassis (80). Wherein the convex post (81) passes through the center gap designed in the driving module (50); the light source cover (60) is fixed on the chassis (80) together with the light source module (70). The lampshade (10) is threadedly connected with the chas...

Abstract

The invention provides an LED ceiling lamp and belongs to the field of application of lighting techniques. The LED ceiling lamp mainly comprises a bottom disc and a shade. The bottom disc is connected with the shade in a threaded manner. A projecting post is arranged at the inner center of the inner surface of the bottom disc. A drive module and a light source module are sequentially arranged from inside to outside by centering on the projecting post. The light source module and the drive module are stacked. The LED ceiling lamp has the advantages the structure is simplified, the heat dissipation structure is simplified and facilitated, temperature rise of LEDs is controlled, and accordingly the temperature of the LED ceiling lamp is decreased and the service life thereof is prolonged; the LED layout is reasonably designed, so that light from the multiple LEDs is evener.

Description

technical field [0001] The invention relates to the technical application field of lighting fixtures, in particular to an LED ceiling lamp. Background technique [0002] Traditional ceiling lamps generally use ring-shaped fluorescent lamps as the light source. The main design of this traditional ceiling lamp is to install the ring-shaped fluorescent lamp on the inner side of the lamp body, and then cover it with a light-transmitting lampshade. After the power is turned on, the light Lighting in the downward direction, this kind of lamp is very popular. [0003] At present, due to the advantages of long life, high luminous efficiency, energy saving and environmental protection, LEDs have been mass-produced and popularized at the same time. As a light source, LEDs will be widely used in ceiling lamps, and it is imperative to replace traditional ceiling lamps that use ring-shaped fluorescent lamps. [0004] On the other hand, as the temperature of LED increases, the luminous ...
