DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a fan in which a blower propeller blade according to a first embodiment of the present invention is configured with EL elements. In FIG. 1, 1 is a blower propeller blade at least a part of which is configured with EL elements, 2 is an EL element lighting control unit that controls lighting of EL elements that make up the blower propeller blade 1, 3 is an EL element lighting control unit 2 are connected,
It is a lighting pattern generation unit that generates a signal for controlling the lighting pattern of the EL element.

In the first embodiment, for example, the three blower propeller blades 1 of a fan are composed of EL elements,
The EL element lighting control unit 2 is the E of the blower propeller blade 1.
The L elements are generated uniformly and evenly, and the lighting pattern generation unit 3 controls the blinking dimming of the EL elements via the EL element lighting control unit 2.

Since the EL element is a surface emitting light source capable of forming a curved surface, the light emitting surface in the curved propeller blade 1 for blowing is uniformly generated. Further, since the emitted light is based on the principle of luminescence, the emitted heat is small and the air blown is not warmed. Further, since it is a thin surface light source, it is possible to suppress the generation of noise without disturbing the air flow during air blowing.

When the blower propeller blade 1 rotates with the EL element turned on at night, a visual afterimage is generated on the rotational movement locus of the EL element of the blower propeller blade 1, producing a decorative illumination effect. Also, the EL is linked to the strength of the air blow.
By adjusting the brightness of the EL element by the element lighting control unit 2, the fan operating state can be shown to the user of the fan as an optical signature. Furthermore, if the three blower propeller blades 1 are composed of EL elements of three colors, red, yellow, and green, and the blower propeller blades 1 rotate fast enough to cause a visual afterimage, the colored light is mixed in time series. When illuminated, the rotational movement locus of the EL element produces a decorative effect in which white light emission starts. Also,
The color of the mixed light is changed by changing the intensity of light emission of the three colors.

Next, the lighting pattern generating section 3 is composed of a timing generating circuit, and the rotation speed of the blower propeller blade 1 and the blinking control of the EL element by the EL element lighting control section 2 are synchronized to make the blower propeller blade 1 of the blower propeller blade 1. If the EL element is turned on when it reaches a certain point within one rotation cycle, E
The light emission shape of the L element shines as if it is fixed at a point in space, and a character display based on the light emission shape of the EL element becomes possible.

FIG. 2 is a block diagram of a fan in which an LED element is installed in a blower propeller blade according to a second embodiment of the present invention. In FIG. 2, 4 is a propeller blade for blowing, 5 is an LED element arranged on the propeller blade for blowing 4 in a plurality of rows in a line from the rotation axis of the propeller blade 4 for blowing to the outer circumferential direction, and 6 is for blowing LE for controlling lighting of the LED element 5 installed on the propeller blade 4
The D element lighting control unit 7 is a lighting pattern generation unit that is connected to the LED element lighting control unit 6 and generates a signal for controlling the lighting pattern of the LED element 5. LED here
The element 5 is a high-brightness / low-power-consumption source and emits light according to the principle of luminescence. Therefore, the element 5 generates less heat and the air blown is not warmed.

In the second embodiment, when the lighting pattern generator 7 sends to the LED element lighting controller 6 a control signal for sequentially turning on the LED elements 5 in a row, the propeller blades for blowing air. A circular pattern of varying size can be drawn within the motion circle of 4. If this is a random point-by-point lighting, the effect of flickering the circle drawn by the afterimage locus of light in the operating circle of the blower propeller blade is given.

In this embodiment, the light-emitting body is an LED, but the light-emitting body is an opening of an optical fiber, the light source for the optical fiber is built in the fan body, and the optical fiber lighting pattern generating section of the optical fiber forms a line-shaped optical fiber. Even if the openings are sequentially turned on, the same effect can be obtained. Further, even if the incandescent light source is used as the light source, since it is housed in the main body, the blown air is not warmed. Further, the weight of the blower propeller blade is not increased, so that the load on the motor can be reduced.

The lighting pattern generating circuit 7 is provided with a synchronizing circuit for synchronizing the rotation of the blower propeller blade 4 and a frequency dividing circuit for frequency-dividing one rotation within an equal time. When the lighting pattern is controlled within each frequency dividing time, It is possible to give the effect of a sign capable of performing dot matrix display of any character or figure in a dot matrix shape within the operating circle of the blower propeller blade 4.

[0022]

As described above, according to the present invention, when an EL element which is a thin surface light source and which can be formed into a curved surface is used, it is possible to emit light without increasing the thickness of the blower propeller blade. Therefore, the blower propeller blade can be made to emit light decoratively without increasing wind noise. Also,
Since the EL element or the LED element has a light emission principle based on luminescence, the EL element or the LED element generates heat due to light emission and does not warm the blown air. Further, by providing an optical fiber on the blower propeller blade, the light source and the light emitting portion can be separated, and an inexpensive incandescent light source such as a light bulb can be separately installed in the fan body.
