Description

Technical Field

[0001] This utility model relates to the field of downlight technology, and in particular to a high-protection downlight. Background Technology

[0002] White light-emitting diodes (LEDs) are a new type of all-solid-state lighting source, hailed as the green lighting source of the 21st century. White LED lighting has three most important advantages: energy saving, environmental protection, and green lighting. In addition, white LEDs also have advantages such as miniaturization, long lifespan, planar design, and high design flexibility, making them promising for a wide range of applications.

[0003] Currently, the demand for decorative lighting in subways is diverse. For example, to create a unique "starry sky" effect by matching the special colors of the subway ceiling, multiple downlights of different specifications need to be installed on the ceiling. Furthermore, due to the special environment inside the subway, there are certain IP65 waterproof requirements for the lighting fixtures. Traditional surface-mounted downlights are indoor lighting fixtures, and their backs are mostly designed with a completely hollow back or a combination of a hollow back cover and a metal shell, mainly for the purpose of easy installation. However, this design obviously cannot meet the IP65 waterproof requirement. If used in subway stations, the humid environment or sudden water seepage inside the station will damage the electrical components of the downlights and cause safety hazards. Secondly, the protection level of existing downlights that can be used in subway stations is basically below IP54. To achieve the IP65 level, it is necessary to apply glue to the entire process, which makes the assembly process inefficient and difficult to maintain. At the same time, improper use of glue may also lead to the volatilization of chemicals that are harmful to LED light sources. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-protection downlight that can be quickly disassembled and assembled, which not only ensures convenient installation and applicability, but also reduces the risk of lamp protection failure.

[0013] Furthermore, it also includes a power supply assembly, which is disposed outside the cylinder. A through hole is provided on the opposite end face of one end face of the cylinder, and a waterproof connector is installed on the through hole. The cable of the power supply assembly passes through the waterproof connector and extends into the inside of the cylinder.

[0014] Furthermore, the opposite end face of the cylinder is stepped.

[0015] Furthermore, the light inlet of the reflector is provided with a mounting bracket, which is detachably connected to the reflector. A light inlet hole is provided through the mounting bracket, which is opposite to and communicates with the light inlet of the reflector.

[0018] The beneficial effects of this utility model are as follows:

[0019] This solution involves placing the reflector at the opening of the cylinder body, with a sealing ring connecting the reflector to the inner wall of the opening. A connecting ring extends outward from the edge of the opening, and a cover is placed over the connecting ring, pressing the reflector and sealing ring together. The cover and connecting ring are threaded together and secured by hand-tightening, effectively reducing the number of screws required for fixing, greatly improving production efficiency.
