Abstract: A hollow brushless motor and a fan include a center shaft, a rotating housing, a stator, a driver, and a permanent magnet. The center shaft is of a hollow structure. A wire passing channel allowing power lines to penetrate through is defined in the center shaft. A through hole communicated with the wire passing channel is defined on one side of the center shaft. An accommodating cavity is formed in the rotating housing. The stator is fixed on the center shaft and is disposed in the accommodating cavity. The driver is electrically connected to the stator. The driver is disposed beside the through hole. The permanent magnet is fixed to an inner side wall of the accommodating cavity and is disposed on an outer periphery of the stator. The fan includes the motor and fan blades.

Abstract: An LED filament lamp having a memory function includes a bulb shell, a lamp cap, a stem, LED light strips and a driver. The lamp cap is disposed on the bulb shell, and the lamp cap and the bulb shell encircle to form an accommodating cavity. The stem is disposed in the accommodating cavity, and the stem has three lead wires. The LED light strips are disposed on the stem are connected to the three lead wires. The driver is disposed in the lamp cap and the drive is connected to the three lead wires. By setting a receiving module and a dimming and toning IC on the drive, color temperature may be adjusted by powering on or off the switch, brightness and colors of the LED filament lamp may be adjusted by a remote controller transmitting 2.4 GHz signals.
