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 power supply device having a thermal insulation function includes a circuit board, and at least one heat-sensitive component and a plurality of heat-generating electronic components that are disposed on the circuit board and spaced apart from one another. The heat-generating electronic components include a transformer, an inductor, an integrated circuit, or a metal oxide semiconductor (MOS). A minimum distance between the heat-sensitive component and the heat-generating electronic components is 7 mm. A thermal insulation area is defined between the heat-sensitive component and the heat-generating electronic components, and none of the heat-generating electronic components is disposed within a 270° range of the thermal insulation area. The heat-generating electronic components are disposed outside the thermal insulation area to separate the heat-sensitive component from a heat source on the circuit board, such that a high temperature of the heat source has less influence on the heat-sensitive component.

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.

Abstract: A lamp includes main bodies, casings, two joint fixing members, two cover plates, a control module and lighting-emitting modules. Each of the lighting-emitting modules is disposed on a side of each of the main bodies and is electrically connected to the control module. Each of the main bodies has a casing fixedly disposed on a side opposite to the lighting-emitting module. A passage is formed between the casing and the main body. The lighting-emitting module has a light-transmitting component and a plurality of light-emitting units corresponding to a plurality of lens structures of the light-transmitting component. The joint fixing members are fixed to at least one of the main bodies and the casings such that the main bodies and the casings are arranged side by side. The passages communicate with each other to form a through passage with the control module disposed therein.

Abstract: A lamp device includes a shell and a light-emitting module. The shell has two guiding fastener members opposite to each other. The light-emitting module includes a carrier board body, fastening members, light-emitting assemblies, and a light-permeable shield module. One side of the carrier board body has two opposite connecting members. The carrier board body is connected with the two guiding fastener members through the connecting members to move relative to the shell along the guiding fastener members. The carrier board body has fastening holes cooperating with the fastening members so that the carrier board body and the guiding fastener members are fastened to each other. The light-emitting assemblies and the light-permeable shield module are fixedly disposed on one side of the carrier board body. The light-permeable shield module does not protrude from the ends of two side walls of the shell that are away from a top wall.
