Fan lamp with fan light control circuit structure integrated with light-emitting diode

The present invention is a fan lamp, especially a fan lamp having a fan light control circuit structure with integrated light-emitting diodes.

With the trend of global warming and energy saving and carbon reduction, air conditioners, which are high in power consumption and cause global warming, are increasingly restricted. One air conditioner is equivalent to the electricity consumption of 20 ceiling fans. When using more than 30 degrees, the fan can fully achieve the effect of cooling and heating. In all fans, only the ceiling fan produces the largest amount of air under the same power consumption (the air volume is the product of wind speed and area), so there are many in the world. The country recommends using energy-saving appliances such as ceiling fans. Moreover, the use of a ceiling fan with an air conditioner can reduce the load of the air conditioner, and can also cause a large temperature difference in the room, which is not easy to cause a cold.

Moreover, as modern people pay more and more attention to interior decoration, ordinary ceiling fans can no longer meet the needs of modern people for interior decoration. Therefore, ceiling fan lamps with practicality and good decorative effect came into being.

Among them, the ceiling fan combined with the light-emitting diode (LED) lamp is the most attractive product in recent years, and the light-emitting diode has high efficiency, long life, not easy to break, high switching speed, high reliability and other traditional light sources. advantage. However, in general, the light-emitting diode lamp is made into a light bulb, so that it is limited in the limited space of the light bulb, and the heat dissipation of the light-emitting diode lamp is extremely difficult. In addition, the illumination angle of a general light-emitting diode bulb is often limited by the directionality of the light-emitting diode wafer, so it is not large, so the lighting design of the ceiling fan may cause problems, and generally for the light-emitting diode bulb. The light can be evenly glazed, and a diffuser can be added, but This lampshade causes a drop in light transmittance.

Furthermore, the most common method of dimming a dimmer is to use a phase-cut dimmer (TRIAC dimmer) for dimming, but the phase-cut dimmer is not a dimmer designed for a diode diode. It is more suitable for the resistive load provided by incandescent lamps or halogen lamps. Therefore, the method of adjusting the LED light by using the phase cutoff dimmer has the following disadvantages: 1. Since the phase cutoff is dimmed by means of interception Dimming, there will be a problem of low power factor; 2. Phase cutoff dimming will produce severe electromagnetic interference (EMI); 3. Phase cutoff dimming will cause low power conversion efficiency of the entire luminaire when deep dimming When the efficiency is lower than 20%; 4. The phase cutoff dimmer is not designed for the light emitting diode, and it is easy to cause the output light to flicker; 5. Phase cutoff dimming will bring serious harmonic distortion (THD) )The problem.

In summary, the conventional fan lamp is integrated into the bulb because of the LED driving circuit, so the phase cutoff dimmer can only be used to adjust the brightness of the LED, so that the power factor of the circuit is low when the dimming is deep. The problem is that the light-emitting diode bulb has a diffusing lamp cover, and there is a problem that the light-emitting diode lamp has low light transmittance. Therefore, an creation is needed to solve the above problems.

The second objective of the present invention is to provide a fan lamp with a fan light control circuit structure integrated with a light-emitting diode, which uses a pulse width modulation method to dim the light-emitting diode, and can accurately dim and not have The problem of low power factor during deep dimming.
