Description

An embodiment of the present invention relates to a luminaire that can be wirelessly controlled.

Conventionally, in a lighting fixture capable of wireless control, a wireless signal transmitted from a remote controller is received by a receiving unit, and a light source is dimmed and controlled according to the received wireless signal.

Further, for example, there are lighting fixtures for high ceilings used for lighting spaces with high ceilings such as facilities. In this luminaire for high ceilings, a light emitting module having a light emitting element is used, and this light emitting module is attached to the lower surface of the radiator. A plurality of heat radiating fins for radiating heat generated by the light emitting element are projected on the upper surface of the radiator. The radiator is supported by a main body chassis arranged above the radiator, and a power supply unit is arranged on the main body chassis. An arm for installing on the ceiling is connected to the main body chassis.

In such a lighting fixture for a high ceiling, when the receiving unit is arranged to enable wireless control, the receiving unit may be affected by the heat from the light emitting module depending on the place where the receiving unit is arranged. The reception strength of the receiver may be low.

Omitted). As the light emitting element 21, for example, an LED is used, but another light emitting element such as an organic EL may be used. The other surface of the substrate 20 is arranged on the lower surface of the radiator 12, and the light emitting module 11 is thermally connected to the radiator 12.

The light emitting module 11 is covered with a translucent cover 22 attached to the lower surface of the radiator 12.

Further, the radiator 12 includes a light source mounting portion 26 and a plurality of heat radiating fins 27 protruding from the upper surface of the light source mounting portion 26. The radiator 12 is made of a metal material such as aluminum. The light source mounting portion 26 and each heat radiation fin 27 may be separated from each other, and each heat radiation fin 27 may be inserted and fixed in a plurality of slits provided on the upper surface of the light source mounting portion 26, or the light source mounting portion 26 and the heat radiation fin 27 may be fixed. May be integrally formed by, for example, extrusion molding.

Further, the main body chassis 13 is provided on both sides of the power supply mounting portion 32 arranged so as to face each other with a space 31 above the radiator 12 and connected to the radiator 12. It has a support portion 33. The main body chassis 13 is formed of, for example, a metal plate.

Further, the power supply unit 14 is mounted on the upper side of the power supply mounting unit 32 of the main body chassis 13. The power supply unit 14 includes a power supply box 37 mounted on the upper side of the power supply mounting unit 32, and a power supply circuit 38 housed in the power supply box 37. Further, the power supply box 37 includes a terminal block box 39 provided on the upper side of the power supply box 37. A terminal block (not shown) for AC power input is arranged in the terminal block box 39. Then, the power supply unit 14 (power supply circuit 38) inputs an AC power source, converts the AC power source into a predetermined DC power source, supplies the AC power source to the light emitting element 21 of the light emitting module 11, and lights the light emitting element 21. Further, the power supply unit 14 (power supply circuit 38) inputs a dimming signal from the wireless module 16 and dimming controls the light emitting element 21 according to the dimming signal.

Further, the arms 15 are a pair of an installation portion 44 arranged above the power supply portion 14 with a predetermined space 43 so as to face each other, and a pair of arms 15 provided at both ends of the installation portion 44 and connected to the main body chassis 13. It has a side 45 of. The tip of the side portion 45 is rotatably and adjustablely attached to the connecting metal fitting 46 attached to the main body chassis 13.

Further, the wireless module 16 is a receiving unit 50 that receives a wireless signal of a predetermined frequency, and a control unit 51 that outputs a dimming signal corresponding to the wireless signal received by the receiving unit 50 to the power supply unit 14 (power supply circuit 38). , And a connection line 52 that electrically connects the receiving unit 50 and the control unit 51. The wireless signal is a signal that controls the lighting state of the light emitting element 21, and includes dimming information. The receiving unit 50 has an antenna for receiving a radio signal, and sends the received signal to the control unit 51. The control unit 51 outputs a dimming signal such as a PWM signal according to the signal input from the reception unit 50 to the power supply unit 14 (power supply circuit 38).

The receiver 50 of the wireless module 16 disposed in the luminaire 10 can be easily disposed in the luminaire 10, is not easily affected by the heat from the light emitting module 11, and is disposed at a position where the reception intensity can be secured. Has been done. This position is above the radiator 12 (radiating fins 27).

If the position of the receiving unit 50 is above the radiator 12 (radiating fin 27), the position a or side surface of the upper surface of the main body chassis 13 or the position c or side surface of the upper surface of the power supply unit 14. It may be either d, the position e on the lower surface of the installation portion 44 of the arm 15, the position f on the inner surface side of the side portion 45, or the position g on the outer surface side.

The position of the receiving unit 50, which can be easily arranged on the luminaire 10 and is not easily affected by the heat from the light emitting module 11 and secures the receiving intensity, is the position f on the inner surface side of the side portion 45 of the arm 15. Alternatively, there is a position g on the outer surface side. Further, the wiring distance between the receiving unit 50 and the control unit 51 is short, and in order to make the receiving unit 50 difficult to see from the outside in consideration of the appearance, the more preferable position of the receiving unit 50 is the arm 15 shown in the present embodiment. There is a position f on the inner surface side of the side portion 45.

Since the control unit 51 is electrically connected to the receiving unit 50 and the power supply unit 14 (power supply circuit 38), it is preferable to dispose of the control unit 51 at a position close to each of the receiving unit 50 and the power supply unit 14. For example, the inside of the power supply box 37 of the power supply unit 14 shown in this embodiment is preferable. When arranged in the power supply box 37, a wiring hole 37a through which the connection line 52 passes is formed in the power supply box 37.

The control unit 51 may be arranged at each position a to g where the receiving unit 50 is arranged together with the receiving unit 50. In this case, the receiving unit 50 and the control unit 51 may be integrated.

Further, FIG. 2 shows a lighting system using the lighting fixture 10. In the lighting system, the lighting state of the lighting fixture 10 is controlled by a terminal 56 including a mobile terminal such as a tablet terminal or a smartphone.

By manipulating the lighting state of the terminal 56, a radio signal of a predetermined first frequency is transmitted from the terminal 56, the controller 57 receives the radio signal, and the controller 57 receives a radio signal of a predetermined first frequency different from the first frequency. A radio signal having a frequency of 2 is transmitted, and the receiving unit 50 of the lighting fixture 10 receives this radio signal, and the lighting state of the lighting fixture 10 is switched.

Then, according to the lighting fixture 10 of the present embodiment, by disposing the receiving unit 50 of the wireless module 16 above the radiator 12 (radiating fins 27), the receiving unit 50 receives heat from the light emitting module 11. It is not easily affected and the reception strength of the receiving unit 50 can be secured.

Further, the receiving unit 50 may be arranged on any of the main body chassis 13, the power supply unit 14, and the arm 15 as long as it is above the radiator 12 (radiating fin 27), but the receiving unit 50 may be arranged on the side portion 45 of the arm 15. By disposing the arrangement, the receiving unit 50 is less likely to be affected by the heat from the light emitting module 11, the receiving intensity of the receiving unit 50 can be ensured, and the receiving unit 50 can be easily attached.
