摘要： A luminaire is provided, which includes a first light source for providing an illumination light and a second light source passing through at least one image pattern for providing a patterned light. The first light source and the second light source are coupled to a driving circuit and covered by a lamp cover. The driving circuit is used to selectively drive at least one of the first light source and the second light source for providing the illumination light and/or the patterned light. A user may turn on or switch different patterns by touching a casing of the luminaire.

摘要： An alternating current (AC) light-emitting device includes a waveform generating unit and an AC light-emitting unit. The waveform generating unit is configured to receive an AC electrical signal and to generate a drive signal by adjusting one of: voltage amplitude of the AC electrical signal during one of positive and negative half-cycles of the AC electrical signal, and waveform level of the AC electrical signal. The AC light-emitting unit includes a first light-emitting component and a second light-emitting component, and the second light-emitting component emits a different wavelength light compared to that emitted by the first light-emitting component. The first and second light-emitting components are electrically coupled to the waveform generating unit to receive the drive signal, and emit light according to the drive signal.

摘要： A method and an apparatus for automatically controlling rotation speed of a cooling fan are provided. The method includes the following steps: Sampling temperature values of the electronic component at Time (n−1) and at Time (n). Then storing the temperature values at Time (n−1) and at Time (n). Then comparing the temperature vale at Time (n−1) with that at Time (n). And then setting the rotation speed of the cooling fan according to the comparison result in the last step. The present invention can not only automatically control the rotation speed of a cooling fan, but also reduce the noise of the cooling fan.
