Abstract: A ceiling fan with a ceiling projection function includes a ceiling fan body and a ceiling fan housing. The ceiling fan body includes a plurality of blades, a motor that drives the blades to rotate, and a hanging rod. The ceiling fan housing is provided with a pattern hole unit and a light-emitting unit. The pattern hole unit has at least one pattern hole. The pattern hole of the pattern hole unit passes through the ceiling fan housing. The light-emitting unit has at least one light-emitting member. When in use, the light-emitting member of the light-emitting unit projects a light beam passing through the pattern hole of the pattern hole unit to project a pattern of the pattern hole of the pattern hole unit outside the ceiling fan housing and above the blades.

Abstract: A ceiling fan upper light includes a light casing. The light casing has at least one side wall made of a light-pervious material. At least one shielding plate made of an opaque material is annularly disposed inside the light casing. At least one groove is annularly disposed inside the light casing. The at least one groove is located between the at least one side wall and the at least one shielding plate. A plurality of light-emitting diodes is annularly disposed inside the light casing. The light-emitting diodes are located in the at least one groove. The light-emitting diodes do not extend out of the at least one groove. The light-emitting diodes emit light toward the opening of the groove, so as to prevent the light from directly irradiating the outside of the at least one side wall, so that the at least one side wall displays the light color of the light-emitting diodes.

Abstract: A quick assembling structure for a ceiling fan with a lamp is provided. The quick assembling structure includes a first seat and a second seat. The first seat has positioning members. The second seat has recesses and guide holes corresponding to the respective positioning members. The second seat has a plurality of elastic plates corresponding to the guide holes. When the positioning members are inserted into the recesses and the guide holes, the positioning members are pushed to pass through the elastic plates for the positioning members to be secured in the guide holes so that the first seat is combined with the second seat. In addition, the guide holes each have an accommodating groove to prevent the positioning members from being separated. The quick assembling structure improves the convenience and safety for the assembly of a ceiling fan with a lamp.

Abstract: A ceiling fan having double-layer blades includes a motor unit, a blade frame unit, a first blade unit, and a second blade unit. The blade frame unit has a blade frame body. The first blade unit includes a plurality of first blades. The second blade unit includes a plurality of second blades. The first blades and the second blades surround the outside of the blade frame body, so that there is no need for the motor unit to provide a motor housing for connecting the first blades and the second blades, thereby saving costs and installation costs. With the arrangement of the first blades and the second blades, the ceiling fan can increase the current of air for cooling.

Abstract: A long-distance speed control system for a brushless DC motor of a fan is provided. The long-distance speed control system includes a switch connected with a mains power supply, a switch circuit, a voltage detection module, a power cord, a processing unit, and a drive unit, which can control the multi-stage rotational speed of the motor. In the field of brushless DC motors for fans, there is no need to use analog-to-digital conversion chips between the mains power supply and the processor, having the advantages of low cost, environmental protection, and reduction of waste of earth resources. Besides, the switch, the switch circuit and the power cord can withstand the mains power supply, having the advantages of less signal attenuation and long-distance transmission.

Abstract: An installation structure of a ceiling fan and an upper illuminating lamp includes a first mounting unit that is disposed on one of a connecting portion of a ceiling fan body and a lamp unit and a second mounting unit that is disposed on the other one of the connecting portion and the lamp unit. The second mounting unit corresponds to the first mounting unit. The first mounting unit and the second mounting unit are connected to each other so that the lamp unit and the ceiling fan body are coupled together, so as to complete the assembly quickly.

Abstract: A down rod installation structure for a ceiling fan has a coupling seat, a down rod, and an elastic member. The down rod is threadedly connected to the coupling seat. The elastic member has a fixed end that is fixed to the coupling seat. The elastic member further has an abutment portion to be engaged in a perforation of the coupling seat and an aperture of the down rod, so that the down rod installation structure invention has the advantages of quick installation and increasing the stability of the ceiling fan.

Abstract: A color temperature and brightness control system for an LED lamp of a ceiling fan includes a switch, a detection module, a determining module, a memory module, a control module, and a drive unit. The detection module detects the actuation of the switch, and the determining module performs a comparison. The control module outputs a control signal to the drive unit according to the calculation result of the determining module and the memory module to drive the lamp to actuate. The color temperature and brightness control system is able to control the lamp to be turned on/off and the brightness and color temperature of the lamp through a single switch.

Abstract: A quick ceiling fan mounting bracket with a safety protection structure has a bracket, two guide rails and an elastic engaging member. The bracket is configured to connect a junction box and a ceiling fan motor unit. The junction box is locked with two locking members. When installed, the locking members are half locked into locking holes of the junction box, and the heads of the locking members are positioned at positioning holes and a force is applied to the elastic engaging member for the locking members to pass through the guide rails. When the head of the locking member is displaced, an engaging portion of the elastic engaging member is against the head of the locking member to achieve the effect of safety protection.

Abstract: A color temperature control device for an LED lamp is disclosed. The color temperature control device is electrically connected to a lamp and comprises a power supply and a power control circuit. The processor can output a color temperature change processing signal. The power control circuit can control the lamp to change the color temperature in a full-on state according to the full-on state of the lamp and a color temperature change processing signal. The power control circuit can control the lamp to change the color temperature in a dimming state according to the dimming state of the lamp and a color temperature change processing signal. Thereby, the color temperature of the lamp can be changed in the full-on state of the lamp or in the dimming state of the lamp, thereby increasing the convenience of use.
