Waterproof and dustproof downlight
First Claim
1. A waterproof and dustproof downlight comprising:
- a housing cylinder havinga cavity having a top opening and a bottom opening; and
a partition board separate from the housing cylinder and inserted into the housing cylinder and mounted horizontally in the cavity;
a top cover, mounted in the top opening of the cavity of the housing cylinder;
an upper waterproof casing, being hollow, being mounted on a top surface of the partition board, and havingan upper chamber defined in a bottom of the upper waterproof casing; and
an upper waterproof O-ring mounted on an annular periphery of the upper waterproof casing, hermetically contacting the top surface of the partition board and the annular periphery of the bottom of the upper waterproof casing, and sealing the upper chamber;
a lower waterproof casing being hollow, being mounted a bottom surface of the partition board and havinga lower chamber defined in a top of the lower waterproof casing;
a lower waterproof O-ring mounted on an annular periphery of a top of the lower waterproof casing, hermetically contacting a bottom surface of the partition board and the annular periphery of the top of the lower waterproof casing, and sealing the lower chamber; and
a lower through hole defined in a bottom of the lower waterproof casing and communicating with the lower chamber;
a power supplying circuit element mounted in the upper chamber of the upper waterproof casing; and
a lighting assembly mounted securely on the bottom surface of the partition board, mounted in the lower chamber of the lower waterproof casing, and electrically connected to the power supplying circuit element.

Abstract
A waterproof and dustproof downlight has a housing cylinder, a top cover, an upper waterproof casing, a lower waterproof casing and a lighting assembly. The housing cylinder has a cavity with a top opening and a bottom opening. A partition board is mounted in the cavity. The top cover is mounted in the cavity of the housing cylinder. The upper waterproof casing is mounted on a top surface of the partition board and has an upper chamber defined in the upper waterproof casing. The lower waterproof casing is mounted on a bottom surface of the partition board and has a lower chamber defined in the lower waterproof casing a top. The lighting assembly is mounted securely on the bottom surface of the partition board in the lower chamber of the lower waterproof casing. The upper and lower waterproof casings provide excellent dustproof and waterproof functions.
