Detailed Description

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the coupling/connection relationships mentioned herein do not mean that the components are directly connected, but mean that a better coupling structure can be formed by adding or reducing coupling accessories according to specific implementation conditions. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.

Embodiment 1, referring to fig. 1, 2 and 3, a low light attenuation LED ceiling lamp comprising: the LED lamp comprises a lamp housing 100, a substrate 200, a reflection cup 300 and an LED lens 400, wherein the lamp housing 100 is provided with a light outlet 410 and a mounting cavity, the substrate 200, the reflection cup 300 and the LED lens 400 are all arranged in the mounting cavity, the LED lamp bead 210 is welded on the surface of the upper side of the substrate 200, the LED lens 400 is covered on the LED lamp bead 210, the bottom of the LED lens 400 is provided with an edge 220 extending outwards, the lower side surface of the edge 220 is attached to the upper side surface of the substrate 200, the reflection cup 300 is provided with a wide cup opening and a narrow cup opening, the narrow cup opening surrounds the cup body of the LED lens 400, the wide cup opening is overlapped with the light outlet 410, the edge of the narrow cup opening is provided with a step 310, the edge 220 is embedded into the step 310, and the side wall of the edge 220 is abutted to the side wall of the step 310.

When the LED ceiling lamp works, the LED lamp bead 210 emits light to pass through the LED lens 400, and the emergent light of the LED lens 400 is reflected out of the wide cup opening by the reflection cup 300. In order to avoid light leakage, the LED lens 400 is arranged to limit the emission angle of the LED lamp bead 210 by the LED lens 400, so that most of the light emitted by the LED lamp bead 210 is emitted from the wide cup opening of the reflective cup 300. The first stage prevents light leakage. A step 310 is provided at the edge of the narrow rim of the reflective cup 300, and the rim 220 is embedded in the step 310, and the side wall of the step 310 and the side wall of the rim 220 are abutted. The second stage of preventing light leakage is performed in such a manner that defects of the LED lens 400 itself, such as lens notches, are considered, and thus, a part of light cannot be confined.

This LED ceiling light is through the structural scheme who prevents the light leak in two stages to make the overwhelming majority that LED lamp pearl 210 sent all jet out from LED lens 400, promote the light efficiency, reduce whole light decay.

In some preferred embodiments, the substrate 200 is an aluminum substrate. As the substrate 200 is made of an aluminum substrate, the LED lamp beads 210 can radiate heat conveniently.

In some preferred embodiments, the inner side wall of the reflector cup 300 is provided with a scaly reflective surface. The reflecting efficiency of the reflecting cup 300 is improved by the scaly reflecting surface.

In some preferred embodiments, a spring-type butting bar 110 is connected to the outside of the lamp housing 100. The abutting end of the spring type abutting rod 110 is provided with a plastic sleeve 111. The installation of the LED ceiling lamp can be facilitated through the spring type abutting rod 110. In order to prevent the spring type abutting rod 110 from being worn and simultaneously improve the abutting friction force, a plastic sleeve 111 is arranged at the abutting end of the spring type abutting rod 110.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and changes without departing from the spirit of the invention.
