Abstract: A power conversion device having a temperature determination function is provided. The power conversion device is disposed on a light fixture and includes a housing, a power converter, and at least one temperature determination component. The power converter and the temperature determination component are disposed within the housing, and the temperature determination component is a temperature fuse. When an ambient temperature of the power converter reaches a preset temperature, the temperature determination component melts to indicate that the power converter is used under the abnormal ambient temperature. Accordingly, the ambient temperature of the power converter can be determined to be abnormal.

Abstract: A lighting device includes a plurality of main bodies, a first casing, a plurality of second casings, a control module, and a plurality of light-emitting modules. One side of each of the plurality of main bodies has the light-emitting modules arranged thereon, and the light-emitting module is electrically connected to the control module. One second casing is fixedly disposed on another side of each of the plurality of main bodies that is opposite to the one side where the light-emitting module is disposed, and a passage is formed between the second casing and the main body. The control module with a plug-in design is disposed in the first casing, so that the control module is arranged away from the plurality of light-emitting modules.
