Abstract:
A luminaire includes a base, a light-emitting unit, and a lamp cover. The base includes a first tube part, a second tube part having an inner diameter smaller than that of the first tube part, and a joint part connected between the first and second tube parts. An inner flow path is defined by at least the first tube part, the joint part, and the second tube part in a coaxial manner. The lamp cover is fixed on the base for covering the light-emitting unit. As such, air heated by the light-emitting unit flows out of the inner flow path to thereby allow cold air to be sucked into the inner flow path.

A wireless input device configured for a computer device is provided. The wireless input device includes a main body and an extension base, wherein the main body has a control unit, an operating unit, a switch, and a first wireless transceiver unit, and the extension base has a processor, a memory unit, a second wireless transceiver unit, and a display. When the switch is triggered, the switch transmits a switch signal to the control unit, and the control unit, according to the operating signal, transmits an adjusting signal to the processor of the extension base in response to the switch signal via the first wireless transceiver unit and the second wireless transceiver unit. The processor changes the parameter(s) in the memory unit according to the adjusting signal and then the changed parameter(s) is stored in the memory unit.
Abstract:
An illumination lamp comprises a lamp body, a light-emitting module, a power supply module, and a circuit module. The lamp body defines an inner space. The partitioning unit is disposed in the lamp body for dividing the inner space into a first space for receiving the power supply module, and a second space for receiving the circuit module. Due to the presence of the partitioning unit, thermal convection between the first and second spaces is prevented to reduce adverse influence of a high temperature of the circuit module on the power supply module.
Abstract:
A computer mouse includes a casing, a skidding pad and a cushion member. The casing has a bottom surface and a side surface adjacent to a peripheral of the bottom surface. The skidding pad is applied on the bottom surface of the casing for sliding upon a working surface. The cushion member is formed at a corner defined between the bottom surface and the side surface of the casing. Additionally, when the computer mouse is stand still on the working surface, only the skidding pad is in contact with the working surface.
