Abstract

PURPOSE:To correctly indicate the dimming state of a lamp on dimming indicators by arranging the dimming indicators displaying the dimming state of a dimming means in the inner periphery range of the circular lamp on the reflecting face of an apparatue main body. CONSTITUTION:A slender dimming indicator slit A is provided perpendicularly to a coupling recess 5 on a reflecting face 4, and a dimming level scale B with a numeral in 60-100% is printed along the slit A. Multiple light emitting diodes D are arranged in response to the slit A as dimming indicators E and illuminated in response to the output level of a dimming means C. When a reception section H receives a dimming signal, the dimming signal is transferred to a remote control unit F, and the unit F outputs the dimming signal to the dimming means C. The means C sets a lamp to the preset dimming state and illuminates the diode D corresponding to the indicator E. The dimming level of the lamp can be correctly indicated.

It is connected to the lighting control circuit of the circuit tile board 16, and the light receiving section H is connected to a remote control unit. In this state, the lower surface portion 42 of the lamp holding portion 21 forms a curved surface flush with the reflective surface 4 of the appliance body 1.

According to this embodiment, when a dimming signal is output from the transmitter, the light receiving section H receives the signal and transmits it to the remote control unit F. Then, the remote control unit F outputs a dimming signal to the dimming means C, and the dimming means C sets the lamp in a predetermined dimming state and also switches the light emitting diode D corresponding to the scale B of the dimming indicator E. to emit light. In this embodiment, for example, 6
If the dimming level is 0%, one light emitting diode D on the center side of the cover 3 will emit light, and if the dimming level is 90%, four light emitting diodes D from the center side of the cover 3 will emit light. In this embodiment, a scale is used, but it is sufficient that the degree of dimming can be recognized numerically or quantitatively, so a scale without a scale may be used. In addition, depending on the dimming level, for example, a reflective LCD
It may also be something that displays the numbers themselves, like a clock.

This embodiment has the following effects.

First, the limoncon unit and the light receiving section are separated, and the limoncon unit is placed within the inner periphery of the annular lamp.
Since the light receiving section is arranged outside the outer periphery of the annular lamp, in the case of a lighting fixture that is hung from the ceiling, stability is improved and malfunction of the light receiving section due to light from the lamp can be reduced.

In other words, if the light receiving part is placed within the inner periphery of an annular lamp, there is no point in giving the light receiving part directionality because light from the lamp enters the light receiving part from all directions. By placing the lamp outside the outer periphery of the lamp and providing directivity outside the lighting fixture, it is possible to block the light from the lamp.

As a means for imparting directivity, in addition to a means for imparting directivity to the light receiving element itself, a means for providing a light shielding member in the vicinity of the light receiving element may be used.

Further, the lamps 22 and 23 are held from the road direction by the holding parts 28, 32, and 33 of the lamp holding part 21, and the lamps 22, 23 are held by the lamp socket receiving part 27 and the holding part 2.
8 from the J direction on the road, so the lamp 22.2
Even if the ring-shaped lamp 22, 23 comes off from the lamp socket receiving part 27 and the lamp socket 30, there is no fear that the annular lamp 22, 23 will fall. When replacing the annular lamps 22 and 23, press the removal operation parts 35 on both sides of the lamp holding part 21 from the operation recess 15, and move the locking pieces 34 inward as shown in FIG. The lamp holder 21 can be removed from the fitting recess 5 of the instrument main body 1 by deforming the lamp holder 21 to release the lock between the locking piece 34 and the locking hole 6. In this way, the lamp holder 21 can be separated from the appliance main body 1 while the annular lamps 22, 23 are attached to the lamp holder 21. This lamp holder 21 is then moved to a position where the annular lamp 22.23 can be easily replaced, thereby facilitating the replacement of the annular lamp 22.23. When holding the lamp holder 21, the lamp 22 with a larger tube diameter is located at the bottom, providing good stability and allowing the lamp holder 21 to be stably placed.
can be easily replaced.
