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.

Abstract: A lamp having the thermal sensing elements disposed at optimal positions includes a heat sink, a light-emitting module and a power supply module. The heat sink includes a plurality of heat dissipating fins, and a heat dissipating channel formed between each two of the plurality of heat dissipating fins, therefore forms an accommodating space. The power supply module is disposed in the accommodating space. The power supply module includes a conductive base and a controlling module. The power source module and thermal sensitive elements are disposed at the lamp cold zone. First thermal sensing elements of the controlling module are disposed at the lamp heat zone to sense the first operating temperature. A processing unit of the control module lowers the output power of the power source module to the light-emitting module when the first operating temperature is greater than or equal to a first critical operating temperature.

Abstract: A heat dissipating device for lightings includes a light source module, a heat sink, and a converter. The heat sink has a substrate and a plurality of heat dissipating fins extending outward from the substrate. A plurality of channels is formed between the heat dissipating fins. Insides of the channels respectively have a port open to the center of the heat sink. Thereby, the channels of the heat sink can effectively direct the airflow into the center of the heat sink, enhancing the heat dissipating effect of the heat sink.
