  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
Embodiment 1 of the present invention will be described below with reference to FIGS.

  In addition, the same number is attached | subjected about the same part as a prior art example, and detailed description is abbreviate | omitted.

  An abduction type motor 102 pivotally supported by a shaft 101, a blade 104 fixed to the rotor 103 of the motor, a control box 106 fixed to the lower surface of the stator 105 of the motor, and this control The light guide plate 1 exposed in a ring shape on the lower surface of the box 106 and having a semicircular cross section at the exposed lower portion, and a plurality of illumination elements 2 provided toward the light guide plate 1 are formed in a single color, for example, a red light emitting diode 3. 2 and a control means 5 housed in the control box 106. As shown in FIG. 2, the control means 5 controls the motor, a motor control part 109, and the illumination part 4 The illumination control unit 6 controls the sensor and the sensor unit 111 that receives an infrared signal from the remote controller.

  FIG. 3 is a diagram showing the positional relationship between the light guide plate 1 and the light-emitting diode 3, so that eight light-emitting diodes 3 emit light in the horizontal direction above the circumference of the ring-shaped light guide plate 1 equally divided into eight. It is arranged. The light incident portion from the light emitting diode 3 of the light guide plate 1 rises vertically upward, and gently enters the downward direction from the surface rising vertically so that the incident light does not directly reflect downward but reflects in the circumferential direction. It is inclined. In addition, the light emitting plate 3 is separated from the light guide plate 1 by a control box 106 so that the light source of the light emitting diode 3 is not directly visible from below, and the light guide plate 1 protrudes upward and sideways. The upper and side surfaces of the light guide plate 1 are covered with a control box 106 so as to reflect light.

  In the above configuration, when the ceiling fan is in operation, the motor 102 is energized from the control means 5 via the motor control unit 109, and the blades 104 rotate to blow air.

  On the other hand, the illumination unit 4 composed of a plurality of illumination elements 2 is turned on via the illumination control unit 6 provided in the control means 5, and the light emitted from the illumination elements 2 enters from the vertical surface of the light guide plate 1 and is inclined. The light guide plate 1 emits light by reflecting slightly downward in the circumferential direction, partially reflecting on the lower surface, and partially passing through the surface. Light reflected by the semicircular lower surface of the light guide plate 1 is transmitted and reflected by the upper surface and side surfaces, and light transmitted by the upper surface and side surfaces is reflected by the control box 106 and enters the light guide plate 1 again. By repeating reflection and transmission by the light guide plate 1 and the control box 106 as described above, the entire light guide plate 1 emits light substantially uniformly. Furthermore, by making the exposed part of the lower part of the light guide plate 1 semicircular, the light emitted from the light guide plate 1 is emitted not only directly below but also uniformly in all directions from the semicircular part.

  Further, when a remote controller (not shown) is operated, the ceiling fan is controlled to operate through the sensor unit 111 provided in the control means 5.

  As described above, according to the first embodiment, the light of the light emitting diode 3 is once put into the light guide plate 1 and the light is emitted from the light guide plate 1 downward from the ceiling fan. Since the light does not enter and disappears and the light emitted from the light guide plate 1 spreads over a wide range, the entire room can be uniformly brightened.

(Embodiment 2)
As shown in FIG. 4, the illumination element 2 is a light-emitting diode having a single emission color, for example, a red light-emitting diode 7, a yellow light-emitting diode 8, a green light-emitting diode 9, and a blue light-emitting diode 10. Are arranged two by two on the upper side which is equally divided into eight.

  In the above configuration, if only the yellow light-emitting diode 8 is lit, the light guide plate 1 emits yellow light, so that the illumination color can be changed to four types.

(Embodiment 3)
Eight light emitting diodes 3 capable of emitting light of three colors of red, green, and blue are arranged above the light guide plate 1 by equally dividing the circumference of the light guide plate 8 into eight.

  In the above configuration, if only one chip of red, green, and blue in one element is lit, three basic colors can be emitted. For example, if red and green chips are lit simultaneously, light is emitted in yellow. When two lights are turned on at the same time, three colors of yellow, light blue, and purple can be emitted. When all of red, green, and blue are lit, light can be emitted in white. By simply changing the number and color of the lights, seven colors are emitted. It becomes possible.

  Furthermore, as shown in FIG. 5, by controlling the lighting time of two or three chips with the pulse width, it becomes possible to emit any color.

(Embodiment 4)
As shown in FIG. 6, the illumination control unit 6 of the control means 5 performs control so as to increase the width of the pulse of the light emitting diode 3 that is turned on in response to the air volume, for example, weak, medium, and strong.

  In the above configuration, when the pulse width to be lit increases, the luminance of the light emitting diode 3 increases, the light guide plate 1 becomes brighter, and the set air volume can be notified by the brightness of the light guide plate 1.

(Embodiment 5)
As shown in FIG. 7, the illumination control unit 6 of the control means 5 has one light-emitting diode 3 when the air volume is weak corresponding to, for example, weak, medium, and strong, and two light-emitting diodes 3 when medium. If it is strong, control is performed so that three light emitting diodes 3 are lit.

  In the above configuration, when the number of light-emitting diodes 3 that are turned on changes, the area of the light-emitting portion of the light guide plate 1 increases, so that the set air volume can be notified.

(Embodiment 6)
As shown in FIG. 8, the illumination control unit 6 of the control means 5 has a yellow light emitting diode 8 when the air volume is weak corresponding to, for example, weak, medium, and strong, and a green light emitting diode 9 when the medium is strong. In this case, the blue light emitting diode 10 is controlled to be lit.

  In the above configuration, when the color of the light emitting diode to be lit changes, the color of light emitted from the light guide plate 1 changes, and the set air volume can be notified.

(Embodiment 7)
As shown in FIG. 9, the illumination control unit 6 of the control means 5 sets the maximum value of the pulse width in one cycle of the light emitting diode 3 that is turned on by the operation of the remote controller, and changes the brightness when changing the luminance. Control is performed so that the pulse width is changed within the range where the maximum value is the upper limit.

  In the above configuration, by setting the maximum luminance, the illumination is not unnecessarily bright, and it is possible to prevent sleep from being disturbed at bedtime.

(Embodiment 8)
As shown in FIGS. 10 and 11, when the air volume is switched from medium to weak, for example, with the remote control when the green illumination is turned on, the illumination controller 6 of the control means 5 turns off the green light emitting diode 9 and turns blue. After the light emitting diode 10 is turned on for a certain period of time, for example, 5 seconds in which it can be recognized that the color has changed reliably, the blue light emitting diode 10 is turned off and the green light emitting diode 9 is turned on to return to the original state.

  In the above configuration, it is not necessary to separately provide the air volume setting display by switching the illumination and the air volume setting display according to time.

(Embodiment 9)
As shown in FIG. 12, the control means 5 is provided with a clock count means 11 for counting time, and the clock count means 11 allows the control means 5 to know the current time.

  In the above configuration, by setting the daytime and nighttime brightness with the remote controller, the illumination control unit 6 of the control means 5 corresponds to the brightness set as shown in FIG. 13 during the daytime from 7 am to 10 pm The light emitting diode 3 is turned on with the width of the pulse to be changed, and after 10 pm, the pulse width is changed to change to the set brightness at night.

  In this way, since the luminance automatically changes between daytime and nighttime, it is not necessary to operate the illumination with a remote control such as at bedtime.

(Embodiment 10)
As shown in FIG. 14, the switch 12 is provided in a place different from the main body of the ceiling fan, for example, a wall or the like so that the power can be turned on and off.

  With the above configuration, when the switch 12 is turned on and the control means 5 is energized, the control means 5 reads the current time from the clock count means 11, and if it is night, the light emitting diode is connected via the illumination control unit 6. 3 is lit.

  In this way, since the illumination is turned on only at night when the switch 12 is turned on, when there is no other illumination in the room, the trouble of searching for the remote control in the dark and turning on the illumination can be saved. In addition, when no illumination is necessary during the daytime, the illumination is not turned on.

  In addition to the use as the main illumination through the light guide plate, it can be applied to illumination and indirect illumination by arranging the light guide plate on the top and side surfaces of the ceiling fan.
