- FIG. 4 is a perspective view of the heat sink of the ceiling fan according to the embodiment of the present invention.
- the feature of the embodiment of the present invention is the configuration of the illumination upper cover 16. Specifically, a heat radiating portion 20 is provided on the side surface of the illumination upper cover 16. Therefore, the heat generated by the light emitting element 18 is radiated from the heat radiating unit 20, and the amount of heat transferred to the control unit 5 above the lighting unit 6 is reduced.
- the heat radiating section 20 is composed of a heat radiating plate 21 which is a plurality of plates extending outward from the side surface of the lighting upper cover 16.
- the heat sink 21 is formed radially from the central axis of the lower illumination cover 15 and extends downward. Thereby, the surface area of the side surface of the illumination upper cover 16 is increased, and the heat radiation from the heat sink 21 is increased.
- the lighting upper cover 16 spreads as it goes downward.
- the upper length 21 a of the heat radiating plate 21 that protrudes from the illumination upper cover 16 is longer than the lower length 21 b that protrudes from the illumination upper cover 16. That is, the heat sink 21 is a trapezoidal plate whose upper side is longer than the lower side.
- the upper surface area of the heat sink 21 is larger than the lower surface area, heat dissipation from the upper portion of the heat sink 21 increases, and the amount of heat transfer from the upper surface of the lighting upper cover 16 to the heat sink 21 increases.
- the lighting upper cover 16 is made of aluminum. Since aluminum has a high thermal conductivity, the amount of heat transferred from the upper surface of the illumination upper cover 16 to the heat sink 21 increases. As a result, conduction of heat generated by the light emitting element 18 to the control unit 5 shown in FIG. 3 is suppressed.
- the LED board part 17 shown in FIG. 3 is flat plate shape.
- a plurality of light emitting elements 18 are mounted on the lower surface 17a of the LED substrate portion, and at least a part of the upper surface 17b of the LED substrate portion is in contact with the upper inner surface 16a of the illumination upper cover. As a result, the heat generated by the light emitting element 18 is transmitted to the illumination upper cover 16 via the LED substrate portion 17, so that the temperature rise in the illumination upper cover 16 is suppressed.
- the illumination upper cover inner surface 16b of the illumination upper cover 16 shown in FIG. 3 is white. Specifically, the illumination upper cover inner surface 16b is painted white. When the light emitted from the light emitting element 18 hits the white illumination upper cover inner surface 16 b, a part of the light is reflected, and the lower part of the light is illuminated through the illumination lower cover 15 to increase the illuminance.
- the lower illumination cover 15 shown in FIG. 3 includes a plurality of openings 15a on the side surface. That is, a plurality of openings 15 a are provided on the side surface of the lower illumination cover 15 so as to face the heat radiating plate 21 provided on the side surface of the upper illumination cover 16. Therefore, heat from the heat radiating plate 21 is released to the outside of the lower illumination cover 15 through the plurality of openings 15a.
- FIG. 5 is a plan view of the LED substrate portion of the ceiling fan according to the embodiment of the present invention.
- each of the plurality of light emitting elements 18 is located on at least three circumferences 31, and the centers of the circles of each circumference 31 are the same. That is, the light emitting element 18 is located on the circumference 31 of a circle having radii R1, R2,. Of the radius differences between two adjacent circles, Rn ⁇ R (n ⁇ 1) is the largest.
- a rectangular plate-shaped LED chip as the light emitting element 18 is mounted on four circumferences 31 having different radii with the receiving unit 19 as the center.
- the long sides of the LED chips are arranged along the circumference 31.
- the light emitting element 18 is arranged such that Rn ⁇ R (n ⁇ 1) is the largest of the radius differences between two adjacent circles. Therefore, the number of the light emitting elements 18 is reduced because the light emitting elements 18 are less on the outer peripheral side of the LED substrate portion 17 and more on the inner peripheral side. As a result, the temperature rise in the illumination upper cover 16 shown in FIG. 3 can be reduced. Furthermore, the illumination upper cover inner surface 16b is white, and the light emitted from the light emitting element 18 located on the circumference 31 of the circle having the radius Rn is reflected. Therefore, even if the light emitting element 18 has few outer peripheral sides of the LED board part 17 and is arrange
- FIG. 6 is a perspective view of the case portion of the ceiling fan according to the embodiment of the present invention.
- a plurality of flat partition portions 26 are arranged on the inner surface of the case portion 7.
- the partition portion 26 has a flat plate shape extending from the inner surface of the case portion 7 in the vertical direction.
- the partition portion 26 is formed radially with the case opening 25 as a center.
- the gap 24 shown in FIG. 2 communicates with the opening 27 of the control case portion 13 shown in FIG.
- the partition portion 26 is formed to bend in the direction opposite to the rotation direction of the blade portion 4. Thereby, when the blade part 4 and the support part 23 shown in FIG. 2 are rotated, the direction of the air entering from a part of the gap 24 and the direction in which the partition part 26 extends inward from the outside of the case part 7 are almost the same. The same direction. For this reason, it is considered that air can further easily enter from the part of the gap 24 along the partition portion 26. As a result, the temperature rise in the control case unit 13 is further suppressed.
- the present invention is useful as a ceiling fan for home use or office use.
