摘要： A method for controlling the rotational speed of a fan of an LED lamp, comprising: presetting a corresponding relationship between a voltage, a current and a temperature for an LED chip in the LED lamp in the controller, as well as presetting a corresponding relationship between the temperature of LED chip and the speed of the fan in the controller, measuring the voltage and current of the LED chip, obtaining the current calculated temperature of the LED chip through the measured voltage and current, and further determining the current desired fan speed through the obtained current calculated temperature, using the controller to control the fan to rotate at the current desired speed, thereby cooling the LED chip. Additionally a corresponding system for controlling the rotational speed of the fan of an LED lamp and an LED lamp including the system.

摘要： This invention provides a ventilation kit adapted to be coupled to a recessed light fixture, and comprises two supporting members. The first is adapted to be coupled with at least one edge of the recessed light fixture, while the second is adapted to be coupled with the grid system of the ceiling. There is also through-hole for air circulation. Mounting the ventilation kit onto an existing recessed light fixture enables the existing recessed light fixtures to have either an air supply or air return ventilation feature. This invention also discloses a recessed light fixture assembly with either an air supply or air return ventilation feature.

摘要： The present invention discloses a lamp, mounted on a socket when in use, comprising a cap, a housing, and a light source, wherein the cap is adapted to connect to the socket, one of the cap and the housing comprises a tubular body, and the other comprises a cylindrical cavity for accommodating the tubular body, and the tubular body rotates in the cylindrical cavity around an axis of the cap and moves along the axial direction of the cap to effect relative rotation and relative telescopic motion between the cap and the housing. The lamp of the present invention allows both relative rotation and relative telescopic motion between the cap and the housing, therefore facilitating adjustment of the illumination direction, and is adaptable to different types of fittings.
