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, a light transmitting cover, an LED light source structure, a driving device, a functional electrical device and a mounting steel plate, wherein an annular convex ring is arranged on the base plate; a cavity is formed in the inner side of the annular convex ring; the driving device and the functional electrical device are accommodated in the cavity; the upper end of the annular convex ring is an annular plane; the LED light source structure comprises a substrate and an LED bulb, wherein the substrate is adhered to the annular convex ring and covers the cavity; the driving device, the functional electrical device, the wire and the like are concealed in the bottom of the substrate and are not exposed, so that the LED ceiling lamp is simple and attractive in appearance; the mounting steel plate comprises a first plane and a second plane; the first plane is arranged on a ceiling through first screws; the second plane is fixedly connected with the inner side wall of the base plate through second screws from outside to inside; the light transmitting cover covers the base plate so that the LED ceiling lamp is simple and attractive in appearance; the light transmitting cover is provided with an inner edge, nuts of the second screws are positioned on the outer side wall of the base plate, and the inner edge is supported and fastened by the nuts; and the LED ceiling lamp is quick, easy and convenient to mount and detach.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED ceiling lamp. Background technique [0002] Ceiling lamps are lamps that are absorbed or embedded in the roof ceiling. Like chandeliers, they are also the main lighting equipment in the room. They are often used in various places such as homes, offices, and entertainment venues. LED has the characteristics of mercury-free, non-toxic, no electromagnetic pollution, no harmful rays, energy saving, environmental protection, and long service life. Therefore, the existing ceiling lamps gradually use LEDs to replace energy-saving lamps as light sources. [0003] Existing LED ceiling lamps generally include a chassis, a light-transmitting cover, an LED light source structure and a driving device arranged on the chassis. around the device. Since the driving device is set in the middle of the chassis, once the translucent cover is set as a transparent cover with a high degree of light transmission, the d...

AI Technical Summary

Problems solved by technology

Since the driving device is set in the middle of the chassis, once the translucent cover is set as a transparent cover with a high degree of light transmission, the driving device and circuits inside the lamp can be seen, and the appearance is not beautiful, so the existing translucent cover is generally set to a high degree of light transmission Poor non-transparent cover not only limits the material and style selection of the light-transmitting cover, but also has low utilization rate of light, low luminous intensity, and poor light effect; in addition, because the driving device is arranged in the middle of the chassis, the central area of ​​the chassis There is no light source and the driving device will block part of the light so that there will be a dark area in the central area of ​​the lamp. In order to reduce the dark area in the existing LED ceiling lamp, the light transmission cover is usually set as an arc-shaped mask that arches upwards. Repeated multiple reflections and diffuse emission in the shaped mask to fill the dark area, because the arc mask is far away from the light source, coupled with the loss of light caused by reflection, resulting in low luminous efficiency, weakened luminous intensity, and insufficient brightness, which can only be achieved by increasing the power A certain brightness, and the shape selection of the translucent cover is limited, resulting in a narrow range of options for the shape and style of the translucent cover

[0004] In addition, in the existing structural design, the light-transmitting cover cannot cover the entire chassis, so that the edge of the chassis is exposed, and the appearance is not beautiful and simple. In addition, an additional installation structure is generally required to install the light-transmitting cover on the chassis. The structure is complex, and the production and assembly are cumbersome and complicated, which increases the production cost of the product
