摘要： A light fixture includes a housing with a hollow inner cavity, and a first ventilation region and a second ventilation region are arranged on the housing; a heat sink disposed in the hollow inner cavity of the housing, wherein the heat sink includes a plurality of fins disposed side-by-side corresponding to the first ventilation region and the second ventilation region; and a blocking mechanism disposed between the heat sink and an inner wall of the housing to divide the hollow inner cavity into a first cavity and a second cavity. The plurality of fins are disposed in the first cavity, the first cavity and the second cavity are isolated from each other. A gap is formed between any two adjacent fins, and the first ventilation region the gap and the second ventilation region are communicating to form a channel. The light fixture has good heat dissipation and waterproof effects.

摘要： A lamp includes a housing, a heat sink, a light source and at least a bracket. The heat sink is disposed within the housing. The light source is connected with the heat sink. The bracket is disposed within the housing, and the bracket includes a main body and a first fixing portion arranged along the outer edge of the main body. The main body of the bracket connected to a side surface of the heat sink is connected to the housing through the first fixing portion to dispose the heat sink in the housing. When the bracket is fixedly connected to the inner wall of the housing, the heat sink can be firmly installed inside the housing and it is not easy to loosen during use, so that the heat sink can continuously and stably dissipate for the lamp.
