  In a lighting fixture having a reflecting mirror, a lamp is disposed on the deep side of the reflecting mirror. A lamp device has been proposed in which the lamp and the lighting device are connected with a short lead wire (see, for example, Patent Document 1). In this prior art lamp device, a lamp is inserted and held in a cylindrical portion of a reflecting mirror having a reflecting portion and a cylindrical portion connected to the reflecting portion, and the cylindrical portion of the reflecting mirror is provided at the center of the printed circuit board of the lighting device. The lamp is inserted into the through hole, and the lamp and the lighting device are connected by a lead wire. Since the lamp and the lighting device can be provided close to each other, the length of the lead wire for connecting the two is shortened. It can be done.

  And the lighting fixture which has arrange | positioned the lamp | ramp in the deep part side of a reflective mirror becomes difficult to radiate | emit the emitted light from a lamp | ramp in the diagonal direction with respect to the direct downward direction of a lighting fixture. Thereby, glare (glare) when the lighting apparatus is looked up from an oblique direction is prevented.

Moreover, the illuminating device which has arrange | positioned the light emitting diode (LED) as a lamp | ramp in the deep part side of a reflective mirror is proposed (for example, refer patent document 2).

An L-shaped attachment member 26 is fixed to the inner surface of the substantially cylindrical body 14 with a screw (not shown), and the terminal block 25 is fixed to the attachment member 26 with a screw (not shown). The terminal block 25 is electrically connected to the circuit board 3 by lead wires 27.

A wiring opening 28 is formed at a portion of the side surface 14 c of the substantially cylindrical body 14 facing the terminal block 25. An external power supply line 29 is inserted from the side surface 14 c side of the substantially cylindrical body 14 through the wiring opening 28, and the power supply line 29 is connected to the quick connection terminal of the terminal block 25. That is, the power supply line 29 is connected to the circuit board 3 by the terminal block 25 and the lead wire 27.
Next, the operation of the first embodiment of the present invention will be described.

  When power is supplied from the power supply line 29 to the terminal block 25, the lighting circuit component 7 of the circuit board 3 operates, and the light emitting diode 2 of the LED module 6 disposed on the circuit board 3 lights up in the circuit board 3. Electric power is supplied from a lighting circuit formed by the circuit component 7 to turn on and emit visible light.

  Since the light emitting diode 2 is located at or near the first opening 11 of the cylinder 4, the emitted light enters the inside of the cylinder 4 directly from the first opening 11. A part of the radiated light is reflected by the inner surface of the reflecting portion 9 of the cylindrical body 4, is emitted from the second opening 13, and is provided on the decorative frame 16 of the instrument body 5. , And exits from the opening of the opening 16a of the decorative frame 16 outward in the direction directly below the appliance body 5.

  Since the light emitting diode 2 is disposed at or near the first opening 11 formed on the one end side 4a of the cylindrical body 4 which is the opposite side of the opening 16a of the decorative frame 16, the light emitted from the light emitting diode is emitted. Is suppressed by the cylindrical body 4 and the decorative frame 16 from being emitted in an oblique direction with respect to the direction directly below the instrument body 5. That is, the light-shielding angle of the light emitting diode 2 when the fixture body 5 is looked up from an oblique direction can be reduced, so that glare and discomfort when the LED illumination fixture 1 is looked up from an oblique direction can be reduced. Can be reduced.

  The light emitting diode 2 is disposed on a circuit board 3 on which a lighting circuit component 7 is mounted as an LED module 6, and the circuit board 3 is a first opening 11 formed on one end side 4 a of the cylindrical body 4. Alternatively, since the light emitting diode 2 is disposed in the vicinity thereof, the dimension between the one end side 14a and the other end side 14b of the substantially cylindrical body 14 of the instrument body 5 can be reduced.

Since the power supply line 29 is connected from the wiring opening 28 of the body 14, the power supply line 29 does not protrude from the LED module 6 and the circuit board 3 toward the end of the one end side 14 a of the substantially cylindrical body 14. That is, since the terminal block 25 is located closer to the second opening 13 of the cylindrical body 4 than the circuit board 3, the dimension between the one end side 14 a and the other end side 14 b of the substantially cylindrical body 14 is the terminal block 25. Therefore, the size of the instrument body 5 in the height direction can be reduced.

Although the cylindrical body 4 is fixed to the decorative frame 16 of the appliance body 5, it may be fixed to the substantially cylindrical body 14 or the lid body 15. Moreover, as for the cylinder 4, the collar part 10 of the one end side 4a may be fixed to the LED module 6 or the circuit board 3. FIG.
