Embodiment approach 1

[0066] figure 1 It is a schematic cross-sectional view of the ceiling fan according to Embodiment 1 of the present invention. figure 2 It is a circuit diagram of the ceiling fan according to Embodiment 1 of the present invention. image 3 It is a front view of the remote controller of the ceiling fan in Embodiment 1 of this invention.

[0067] Such as Figure 1 ~ Figure 3 As shown, the ceiling fan of the present invention includes: an outer-type motor 2 supported by a hollow shaft 1, a blade 3 fixed on the rotor of the motor 2, a control box 4 fixed on the lower end of the shaft 1, exposed to the control On the lower surface of the box 4 , an illuminating unit 7 in which a plurality of illuminating elements are formed of visible light emitting diodes 6 , and a control unit 8 accommodated in the control box 4 . The control unit 8 is composed of a microcomputer 8 a, a motor control unit 9 for controlling the motor 2 , an illumination control unit 10 for controlling the illu...

Embodiment approach 2

[0076] Figure 4A It is a circuit diagram of the ceiling fan in Embodiment 2 of this invention. 4B is a time chart showing the number of flashes of the visible light emitting diode according to Embodiment 2 of the present invention.

[0077] Such as Figure 4A , 4B, in the case of using the remote control to change the air volume, the control unit 8A makes only the number of visible light-emitting diodes 6A corresponding to the air volume flash through the lighting control unit 10A.

[0078] In the above structure, components such as transistors for individually controlling the plurality of visible light emitting diodes 6A are not required, and the air volume can be indicated by a circuit with a simple circuit structure and a small area.

Embodiment approach 3

[0080] Figure 5A It is a circuit diagram of the ceiling fan in Embodiment 3 of this invention. 5B is a timing chart showing changes in luminance of visible light emitting diodes used in the ceiling fan according to Embodiment 3 of the present invention.

[0081] Such as Figure 5A , 5B, in the case of using the remote control to change the air volume, the control unit 8B can increase the brightness of the visible light-emitting diodes 6B sequentially through the lighting control unit 10B until the brightness corresponding to the air volume.

[0082] In the above configuration, since the luminance of the visible light emitting diode 6B is changed by changing the timing of energizing the visible light emitting diode 6B, components such as transistors for individually controlling the plurality of visible light emitting diodes 6B are not required. In addition, the air volume can be represented by a circuit with a simple circuit structure and a small area.

Abstract

Provided is a ceiling fan which comprises a vane (3) fixed to a rotor of a motor (2) fixed at its center with a shaft (1), a lighting part (7) consisting of a plurality of lighting elements (5) exposed to the lower face of a control box (4) fixed to the lower end of the shaft (1), and a control means (8) stored in the control box (4). The control means (8) which controls the motor (2) and the lighting part (7) has a sensor part (12) for receiving infrared signals from a remote control. Thus, the ceiling fan is obtained with the body wholly shaped smaller while allowing easy wiring.

Description

technical field [0001] The present invention relates to a ceiling fan provided with an illuminating part. Background technique [0002] The ceiling fan used in conjunction with the air conditioner supplies cool air from the top in summer, and at the same time diffuses the cold air gathered on the ground when cooling the equipment; The warm air moves towards the ground. The function of equalizing the indoor temperature is comfortable and beneficial to health, and it is becoming more and more popular because of the economical effect of energy-saving operation of air conditioners. [0003] Conventionally, as an example of such a ceiling fan, for example, Japanese Patent Application Laid-Open No. 10-306792 discloses a ceiling fan provided with lighting fixtures. [0004] Below, refer to Figure 23 , Figure 24, illustrates this ceiling fan. [0005] Figure 23 A sectional view of an existing ceiling fan. Fig. 24 is a cross-sectional view showing a state in which a lighting fi...
