  When an LED is used as the illumination device, the LED generates heat, and thus heat dissipation is required. Therefore, a heat radiating member such as a heat sink is provided. The heat generated from the LED is transmitted to the heat radiating member and is radiated from the heat radiating member. If such a heat radiating member is provided, the ion generator becomes larger and heavier and cannot be smoothly attached to the ceiling.

  By the way, the ion generator is provided with a fan for discharging the generated ions. If the ventilation by this fan is utilized, it can be radiated from an illuminating device. In view of the above, an object of the present invention is to provide an ion generator that cools an illuminating device by using air blown from a fan.

It is a thing.

  Since the blowing direction by the fan and the irradiation direction of the lighting device are the same direction, the lighting device can be positioned in the wind for blowing out ions, and the blowing of the fan can be used for cooling the lighting device.

  A ventilation path that guides the generated ions to the outside is formed in the case, and a lighting device is arranged on the outlet side of the ventilation path. The lighting device can be cooled by the wind flowing through the ventilation path.

  The lighting device includes a mounting board on which a plurality of light emitting elements are mounted. The mounting board is disposed along the peripheral edge of the ventilation path, and a part of the mounting board protrudes into the ventilation path. The mounting board is exposed to the wind and is dissipated from the mounting board without disturbing the air flow.

  Electronic components for collecting information or transmitting information are mounted on a mounting board protruding into the ventilation path. The vacant space can be used effectively, and the installation space for such electronic components can be saved.

  A ventilation hole is formed in the mounting board, and the ventilation hole serves as an outlet for blowing out ions. The wind in the ventilation path passes through the mounting board, and the area of the mounting board that hits the wind can be increased.

  According to the present invention, the mounting plate whose temperature is increased by the heat generated by the lighting device can be cooled by the wind for blowing out ions. Thereby, it is not necessary to provide a heat radiating member, and the number of parts can be reduced and the apparatus can be downsized.

  The lighting device 3 includes a plurality of light emitting elements 20 and a mounting plate 21 on which the light emitting elements 20 are mounted. The lighting device 3 is provided at the outlet of the ventilation path 10. The mounting board 21 is disposed in the opening on the front surface of the case 4. The mounting board 21 is a circuit board formed in a disk shape. The outer peripheral portion of the mounting board 21 is an annular mounting portion 22. A plurality of light emitting elements 20 made of LEDs are mounted on the same circumference at a fixed interval on the mounting portion 22. The mounting portion 22 is attached to the periphery of the outlet of the ventilation path 10 with screws. The front surface of the mounting portion 22 is covered with a translucent cover 23.

  An island portion 24 is formed at the center of the mounting board 21, and the island portion 24 is connected to the mounting portion 22 by a plurality of bridge portions 25. Electronic parts for collecting information or transmitting information are mounted on the disk-shaped island 22. Examples of such electronic components include a human sensor that detects the presence or absence of a person in the room, a notification lamp such as an LED that notifies various types of information, an illuminance sensor, and an odor sensor. Here, the human sensor 26 and the notification lamp 27 are mounted on the island portion 24. Printed wiring is applied to the bridge portion 25, and the mounting portion 22 and the island portion 24 are electrically connected. The island part 24 and the bridge part 25 are covered with a non-translucent front cover 28 and a rear cover 29. The front cover 28 covers the front surfaces of the island portion 24 and the bridge portion 25 with a gap therebetween and is held by the rear cover 29. The rear cover 29 covers the back surface of the island portion 24 and the bridge portion 25 with a gap, and is attached to the inner wall of the case 4. Wind flows through these gaps.

  The inner periphery of the mounting portion 22 faces the ventilation path 10. Moreover, the bridge part 25 and the island part 24 which are a part of the mounting board 21 are located in the ventilation path 10 and protrude into the ventilation path 10.

  The mounting board 21 has a vent hole 30 communicating with the ventilation path 10, and the vent hole 30 is formed on the inner peripheral side of the mounting portion 22. A plurality of openings between the mounting portion 22 and the island portion 24 serve as the air holes 30. The vent hole 30 communicates with the ventilation path 10 and serves as an outlet of the case 4 for blowing out ions. Here, the bridge part 25 is made into three so that ventilation may not be prevented, and ion is discharge | released indoors smoothly from a blower outlet.

  A main board 31 is provided on the side wall of the ventilation path 10. On the main board 31, a control device including a CPU and the like, a power supply device that supplies power to each device, and the like are mounted. The main board 31 and the mounting board 20 are electrically connected by lead wires. The control device controls the ion generator 1 and the fan 2 and the lighting device 3 by operating a remote switch installed in the room.

  Ions generated from the ion generator 1 are carried toward the outlet through the ventilation path 10 by the blower of the fan 2. Then, the ions are blown out into the room from the vent hole 30 of the mounting board 21. The light emitting element 20 arranged so as to surround the plurality of air holes 30 emits light, and the front is irradiated. The blowing direction for blowing out ions and the irradiation direction of the lighting device 3 are the same direction. In the illuminated area, blown out positive ions and negative ions will be present.

  The ion sensor 11 detects ions generated from the ion generator 1. The generated ions flow toward the ion sensor 11 by the rotation of the fan 2, and the ion sensor 11 can reliably detect the presence or absence of ions. When the ion sensor 11 detects no ions, the control device stops the operation of the ion generator 1 and operates the notification lamp 27. Thereby, the occurrence of abnormality is notified. Further, the control device controls the operations of the ion generator 1 and the lighting device 3 based on the outputs of various sensors such as the human sensor 26.

  When the illumination device 3 operates, the light emitting element 20 generates heat. Heat is transmitted from the mounting portion 22 to the island portion 24 through the bridge portion 25. By the operation of the fan 2, the wind flows through the ventilation path 10, and the wind blows out from the vent hole 30 and passes through the mounting board 21. At this time, wind strikes part of the mounting board 21 in the ventilation path 10, that is, the bridge portion 25 and the island portion 24. Further, high-temperature air around the mounting portion 22 is sucked into the wind passing through the vent hole 30, and an air flow is generated around the mounting portion 22. In this way, heat is radiated from the mounting board 21.

  As described above, the mounting plate 21 on which the lighting device 3 is mounted is disposed at the outlet of the ventilation path 10, so that the lighting device 3 can be cooled using the air blown by the fan 2. And when a part of mounting board 21 protrudes in the ventilation path 10, the wind passes the mounting board 21 and the area of the mounting board 21 which touches a wind becomes large. The heat dissipation efficiency from the mounting board 21 is increased. Therefore, the illuminating device 3 can be cooled efficiently and a heat radiating member can be reduced.

  In addition, by providing the main board 31 and the ion generator 1 so as to face the air passage 10 around the fan 2 with the fan 2 as the center, even if the electronic components mounted on the main board 31 generate heat, Heat dissipation is promoted by the wind flowing through the ventilation path 10. The main substrate 31 can be cooled, and there is no need to provide a heat dissipation member. In addition, since the static electricity can be removed by the generated ions, the electronic components on the main board 31 can be prevented from being destroyed by the static electricity.

  As described above, in the ion generator of the present invention, the case 4 includes the ion generator 1 that generates ions, the fan 2 that blows out the generated ions to the outside, and the lighting device 3. The direction and the irradiation direction of the illumination device 3 are the same direction.

  Thus, by making the blowing direction by the fan 2 and the irradiation direction of the lighting device 3 the same direction, the lighting device 3 can be installed in a space for blowing out ions, and the fan 2 is blown by the lighting device. It can be used to cool the ion generator and the ion generator can be made compact.

  A ventilation path 10 that guides the generated ions to the outside is formed in the case 4, and the lighting device 3 is disposed on the outlet side of the ventilation path 10. Thereby, since the illuminating device 3 is located downstream of the fan 2, the illuminating device 3 can be cooled with the wind which flows through the ventilation path 10. FIG.

  The lighting device 3 includes a mounting board 21 on which a plurality of light emitting elements 20 are mounted. The mounting board 21 is disposed along the periphery of the ventilation path 10, and a part of the mounting board 21 protrudes into the ventilation path 10. . Thereby, the mounting board 21 whose temperature is increased by the heat generated by the light emitting element 20 can be exposed to the wind passing through the ventilation path 10, and heat dissipation from the mounting board 21 can be promoted.

  Electronic components for collecting information or transmitting information are mounted on the mounting board 21 protruding into the ventilation path 10. Thereby, the installation space of such an electronic component can be ensured and a new installation space can be made unnecessary.

  A ventilation hole 30 is formed in the mounting board 21, and the ventilation hole 30 serves as an outlet for blowing out ions. Thereby, the wind of the ventilation path 10 passes the mounting board 21, and the mounting board 21 from which temperature becomes high can be cooled efficiently.
