Abstract

A ceiling lamp comprises a mounting base (10), a power supply module (20), a chassis (30), a control circuit (40), an LED base plate (50), and a lampshade (60). The power supply module (20) is mounted on the mounting base (10). A raised ring (31) raised in a direction opposite to the mounting base (10) is disposed in the center of the chassis (30). The power supply module (20) is accommodated in the raised ring (31). A first groove (32) recessed to the direction of the mounting base (10) is disposed around the raised ring (31). The control circuit (40) is mounted on the chassis (30), and is located in the first groove (32). LED lamp beads (51) of multiple colors are attached to the LED base plate (50). The lampshade (60) is detachably mounted on the chassis (30) by means of a clamping pin buckle member (70). A neon lamp effect is achieved by using LED lamp beads (51) of multiple colors. The power supply module (20), the LED base plate (50) and the control circuit (40) of the lamp are not located on a same plane, so that the arrangement space of the LED base plate (50) is greatly released, and the LED lamp beads (51) can be placed without limitation; the LED lamp beads (51) are distant from a heat source, and accordingly the reliability and the service life of the lamp are improved.

Ceiling light

Technical field

[0001] The utility model relates to the field of LED lamps, in particular to a ceiling lamp.

Background technique

[0002] In life, neon lighting is generally used in entertainment venues (such as KTV) to enhance the entertainment atmosphere. Compared with household lighting fixtures, white light sources are generally used, and the colors of entertainment venues lack color and cannot provide a good entertainment atmosphere. . So in general gatherings, people usually go to the entertainment venues outside to make consumption. However, there are various problems in specialized entertainment venues, such as the need for queues and high consumption.

[0003] Of course, it is possible to use a luminaire of a different illuminating color to achieve a neon effect, but this method is costly. For example, the current ceiling lamp generally has no chassis or only a flat chassis. The driving power of the lamp is directly mounted on the flat chassis. The driving power source as the heat source is too close to the lamp bead and the lamp cover, so that the setting space of the lamp bead is limited. Too close to the heat source, resulting in low reliability and short life. In addition, it is inconvenient to drive or replace the lamp cover on the drive power plane chassis, and it will cause the lamp bead to illuminate the mounting structure, causing a shadow on the lamp cover.

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. [0020] Please refer to FIG. 1. In the preferred embodiment of the present invention, a ceiling lamp includes a mounting base 10, a power module 20, a chassis 30, a control circuit board 40, an LED substrate 50, and a lamp cover 60.

[0021] The power module 20 is mounted on the mounting base 10; the chassis 30 is mounted on the mounting base 10. The center of the chassis 30 of the special structure is provided with a convex ring 31 protruding in the opposite direction of the mounting base 10, and the power module 20 is received in the convex ring. 31, a convex groove 31 is provided around the first recess 32 in the direction of the mounting seat 10;

[0022] The control circuit board 40 is mounted on the chassis 30 in the first recess 32. The control circuit board 40 is provided with a wireless signal receiving circuit for receiving a remote control signal to change the color of the lamp. In this embodiment, the convex ring 31 is a circular convex ring having the same shape as the chassis 30; the first groove 32 is the same annular groove as the chassis 30; in other embodiments, the convex ring 31 may be rectangular, elliptical, etc. The first recess 32 may be a rectangular, elliptical recess that can receive the control circuit board 40.

[0023] The LED substrate 50 is fixed to the chassis 30 by screws or adhesive to cover the first recess 32, that is, it may not be completely covered. The LED substrate 50 is provided with a multi-color LED lamp bead 51; the LED substrate 50 can be modularized, and different LED light source substrates can be selected according to different lighting requirements, or the LED substrate 50 can be changed by changing the LED string.
