Modes for Carrying Out the Invention

[0016] <Embodiment 1> <Configuration> Fig. 1 shows a perspective view of the lighting device 100 according to the present embodiment. The lighting device 100 is a spotlight that can be attached to the wiring duct 180. The lighting device 100 includes a light source 130 as shown in Fig. 4 which is a partial side view and a partial cross-sectional view, and this is a general term for a single-color light source 130N, a two-color light source 130T, and a three-color light source 130S. Further, the lighting device 100 may be a dimmable lighting device 100A including a single-color light source 130N, a lighting device 100B capable of changing the color temperature and dimming including a two-color light source 130T, or a lighting device 100C capable of changing the chromaticity and dimming including a three-color light source 130S.

[0017] In the following description, the terms "front F direction", "rear B direction", "upper U direction", and "lower D direction" are used with reference to the axis AX in Fig. 1. Also, the direction orthogonal to the axis AX and the vertical direction may be described as left and right.

[0018] In Fig. 1, the lighting device 100 includes a lamp body 110, and the lamp body 110 includes a lamp body rear surface 111, a lamp body side surface 112, and a light emitting portion 160. The lighting device 100 also includes an arm 170 rotatably attached to the lamp body side surface 112, and an attachment portion 178 at the other end of the arm 170 and attached to the wiring duct 180. Inside the arm 170, there is an electric lamp wire 138 for transmitting the commercial power supplied to the wiring duct 180 to the power source 140. The lamp body 110, the arm 170, and the attachment portion 178 together will be referred to as the outer shell portion 101 of the lighting device 100.

[0019] The axis AX, which is the orientation of the lighting device 100, can be rotated horizontally by the rotation of the arm 170 in the Φ direction with respect to the attachment portion 178. Also, by rotating the arm 170 in the θ direction, the orientation can be changed to an appropriate direction from downward to upward.

[0020] As shown in FIG. 2, which is a rear view of the lamp body of the lighting device 100, a wireless switch 144 is attached to the rear surface 111 of the lamp body, and a mark 144M for identifying whether the function of wireless control is on or off is printed. By moving a wireless switch slider 144S that contacts the knob of the wireless switch 144, it is possible to switch the on / off of the function of wireless control.

[0021] When a setter such as a lighting device installer turns on (enables) the wireless switch 144, the wireless control function of the lighting device 100 is enabled, and the light quantity and lighting color can be controlled by wireless communication from a lighting control device 190 composed of a tablet, smartphone, PC, or remote control. Hereinafter, the control of the light quantity is called dimming, and the control of the lighting color is called color adjustment. When the wireless switch 144 is turned off (disabled), the wireless control function of the lighting device 100 is disabled, and it operates at a predetermined dimming rate (for example, dimming rate 100%).

[0022] As another example of the rear view of the lamp body of the lighting device 100, FIGS. 3(a) and (b) show the cases where the wireless control is enabled and disabled, respectively. A wireless switch 144 is attached to the rear surface 111 of the lamp body. In order for the setter to identify whether the function of wireless control is enabled or disabled, the lower part 144P of the switch is visible when the function of wireless control is enabled, and the lower part 144Q of the switch is visible when the function of wireless control is disabled. It is preferable that the color of the lower part 144P of the switch is different from the color of the lower part 144Q of the switch, and it is preferable that the color of the lower part 144P of the switch is different from the color of the wireless switch slider 144S (knob part). On the other hand, it is preferable that the color of the lower part 144Q of the switch is the same as the color of the wireless switch slider 144S. For example, the color of the lower part 144P of the switch is green, and the colors of the lower part 144Q of the switch and the wireless switch slider 144S are black. Thereby, the setter can identify the on / off of the wireless control. Thereby, it is possible to identify the on / off of the wireless control without printing the mark 114M. When the mark 144M is not displayed, it is difficult for users other than the setter to know the on / off of the wireless control, and there is an advantage that the wireless switch is not inadvertently operated by the user.

[0023] FIG. 4 is a partial side view and partial cross-sectional view including the axis AX of the lamp body 110. Inside the lamp body 110, there are a heat sink 120, a light source 130, a reflector 132, a lens 134, a power supply 140, a signal cable 142 for a wireless module, a wireless module socket 146, and a wireless module 148 which is a wireless communicator, including the parts described in FIG. 5. The wireless module 148 is detachable from the wireless module socket 146.

[0024] Note that the length of the lamp body 110 of the lighting device 100 is 190 mm and the outer diameter is 85 mm, but this is only an example, and lighting devices with different sizes may also be used.

[0025] <Conceptual Wiring Diagram around the Wireless Switch> FIG. 5 shows a conceptual diagram of the circuit including the wireless switch 144 of the lighting device 100. The wireless module 148 has a function as a wireless transceiver and incorporates an antenna. The wireless module socket 146 is a socket for connecting the terminals of the wireless module 148.

[0026] The power supply 140 converts the power supplied from the commercial power supply through the electric lamp wire 138 into a drive output for the light source 130. Inside the power supply 140, there are an IC 141A and a circuit 141B. The circuit 141B is composed of individual elements such as diodes, resistors, and FETs. The power supply 140 is connected to the wireless module socket 146 and the signal cable 142 for the wireless module (including a signal line 142S, a power supply line 142P, and a ground line 142G).

[0027] When the wireless switch 144 is on, power is supplied to the wireless module socket 146 via the power supply line 142P. The wireless module 148 receives a wireless control signal having an identification signal addressed to itself, and converts the lighting control signal in the wireless control signal into a PWM (Pulse Width Modulation) lighting control signal corresponding to the dimming rate from the signal line 142S and inputs it to the IC141A of the power supply 140. On the other hand, when the wireless switch 144 is off, the power supply line 142P is cut off and the wireless module 148 does not operate. Therefore, the level (voltage) of the signal line 142S is made constant by the circuit 141B, and a signal with a dimming rate of 100% is input to the IC141A. The ground line 142G is commonly used for both the lighting control signal and the power supply.

[0028] The IC141A of the power supply 140 supplies an LED drive output controlled based on the lighting control signal to the light source 130 through the drive cable 135. When using a single-color LED, the drive cable 135 consists of a drive line 135A and a ground line 135G. For example, when independently driving a three-color LED, drive lines 135A, 135B, 135C and a ground line 135G are used.

[0029] As described above, in order to set the default lighting control conditions when the wireless switch 144 is off, the circuit 141B is used. However, for example, a memory 141M in which preset default lighting control conditions are stored may be used in the circuit 141B in FIG. 5. In particular, when having a plurality of default lighting conditions described later, the memory 141M can be preferably used.

[0030] <Operation control> The lighting control device 190 shown in FIG. 1 can perform dimming, color adjustment, and schedule operation of the lighting device 100. By the schedule operation, for example, it can be set to turn on when the opening time or the start time of work arrives, and turn off at the closing time or the end time of work. If the lighting device 100 is dimmable and color-adjustable, it can be changed according to the time, such as a color temperature of 6500K and a dimming rate of 100% in the morning, and a color temperature of 2700K with a low color temperature and a dimming rate of 60% in the evening, as lighting suitable for the human biological rhythm.

[0031] <Operation when the wireless switch is OFF> When the wireless switch 144 is OFF (turned off), control by the lighting control device 190 cannot be performed. In that case, the dimmable lighting device 100A performs lighting under the preset default lighting control conditions, for example, at a dimming rate of 100%. In the case of the dimming / color-tuning lighting device 100B or the lighting device 100C using three-color LEDs, the default lighting control conditions are, for example, a dimming rate of 100% and a color temperature of 5500K. When the wireless switch 144 is OFF, the lighting device 100 is turned ON / OFF by turning ON / OFF the main power switch installed in the building.

[0032] Such default lighting control conditions may be stored in the memory 141M. The storage in the memory 141M may be written by a memory reader outside the lighting device 100, or after the lighting device 100 is installed, the "preset lighting conditions" may be written into the memory 141M by wireless communication.

[0033] <Advantage 1 of the wireless switch> If a lighting device without a wireless control function is used instead of a lighting device equipped with a wireless switch, problems related to the setting of the lighting device that can be controlled and the use of the radio wave band do not occur. Compared with such a lighting device, the following advantages can be cited for the lighting device with a wireless switch.

[0034] · When a problem related to wireless control occurs, the wireless control function can be temporarily stopped, or limited to some appliances.

[0035] · When performing wireless control in the future, since wireless control can be performed only by switching the wireless switch, there is no need to replace the lighting device.

[0036] <Advantage 2 of the wireless switch> Even if the wireless module 148 is removed from the wireless module socket 146 without using the wireless switch 144, the same effect as turning off (switching off) the wireless switch 144 can be obtained. In contrast, the following advantages can be cited for the lighting device with a wireless switch.

[0037] · Since the wireless module 148 is installed inside the lamp body 110, the wireless module 148 cannot be removed without, for example, removing the screws on the back surface 111 of the lamp body. However, by using the wireless switch 144, it is not necessary to disassemble the lamp body.

[0038] · When the wireless module 148 is removed, it needs to be properly stored and there is a risk of loss. However, by using the wireless switch 144, there is no need for storage and no risk of loss. · By using the wireless switch 144, it is possible to immediately return to a state where wireless control is possible.

[0039] <Advantage 3 of the wireless switch> For example, compared with the case of providing a control ON / OFF switch in a dimmer or its wireless version, a lighting control device, the following advantages can be cited for the lighting device with a wireless switch.

[0040] · By performing the on / off of the wireless control function in the lighting device on the wireless switch provided in the lighting device itself, it is possible to intuitively recognize which lighting device's wireless control function is turned off.

[0041] · Since the lighting device is usually installed on the ceiling, the wireless switch provided in the lighting device 100 is not accidentally operated by the user who is simply present in the room.

[0042] <Modification example of the installation position of the wireless switch> The installation position of the wireless switch 144 is not particularly limited. For example, it may be installed at the upper position of the side surface 112 of the lamp body shown as the wireless switch 144B in FIG. 1.

[0043] <Modification Example of Wireless Switch Function> The wireless switch 144C shown in FIG. 6(a) can select one of a plurality of preset lighting control conditions (for example, 70 and 100 indicated by the mark 144M2 correspond to dimming rates of 70% and 100%) when the wireless control function is turned off. The wireless switch 144D shown in FIG. 6(b) can select one of a plurality of preset lighting control conditions (for example, 4200, 3500, and 3000 indicated by the mark 144M3 correspond to color temperatures of 4200K, 3500K, and 3000K) when the wireless control function is turned off.

[0044] As described above, it was explained that the same effect can be obtained by removing the wireless module 148 instead of turning the wireless switch 144 on / off. However, in that case, there is only one preset lighting control condition. The wireless switch 144C and the wireless switch 144D have the advantage of being able to select one of a plurality of preset lighting control conditions.

[0045] The wireless switch 144C and the wireless switch 144D are switches that perform wireless on / off and selection of preset lighting control conditions in one operation. However, separately from the wireless switch, another switch for selecting preset lighting control conditions that operates when the wireless switch is turned off may be provided.

[0046] <Embodiment 2> <Configuration> The lighting device 300 of this embodiment is a spotlight that can be attached to a wiring duct 380 installed on the ceiling 395.

[0047] FIG. 7 is a perspective view of the lighting device 300. In FIG. 7, the lighting device 300 includes a lamp body 310 and a power supply case 372, and both are rotatably connected in the horizontal and vertical directions by an arm 370. The outer contour parts of the lamp body 310, the arm 370, and the power supply case 372 are combined and referred to as the outer contour part 301 of the lighting device 300.

[0048] On the lamp body 310 side, a heat sink 320, a light source 330 installed on the heat sink 320, and a lens 334 are provided.

[0049] Inside the power supply case 372, a power supply 340 is installed. The power supply case 372 is provided with a front attachment part 376 for connecting to a wiring duct 380, a lever 375 for moving the front attachment part, and a rear attachment part 378. Commercial power is input from the front attachment part 376 to the power supply 340.

[0050] As shown in FIG. 8 showing the back of the power supply case 372, a wireless module 348 and a wireless switch 344 are provided on the back of the power supply case 372, and a mark 344M for identifying the on / off of the wireless control function is printed. By moving the wireless switch slider 344S, the on / off of the wireless control function can be switched.

[0051] Referring to FIG. 5, the power supply 340 has a function of converting the power supplied from a commercial power supply (corresponding to the electric light wire 138 in FIG. 4) into a drive output for the light source 330. For controlling the drive output, the power supply 340 includes a wireless module socket 346. The wireless module 348 receives a wireless control signal addressed to itself sent from the lighting control device 390 and transmits the lighting control signal included in the wireless control signal to the power supply 340. Here, when the wireless switch 344 is off, power is not supplied to the wireless module 348, so the lighting control signal is not transmitted to the power supply 340. In that case, the power supply 340 supplies a drive output under the preset default lighting control conditions to the light source 330.

[0052] <Embodiment 3> <Overview> A perspective view of the lighting device 300 according to this embodiment is shown in FIG. 9. The lighting device 500 includes a fixture body 510 directly attached to the ceiling and a light source unit 520 attached to the fixture body 510. The light source unit 520 can be attached to, removed from, and temporarily fixed to the fixture body 510. Since the fixture body 510 and the light source unit 520 can be attached and removed, screws or suspension bolts for attaching the fixture body 510 to the ceiling, and the power supply case 525C and wiring on the upper surface side of the light source unit 520 can be hidden. As an example, the width of the lighting device is 2 cm and the length is 120 cm, and the fixture has a shape designed with consideration for design.

[0053] Cross-sectional views of the fixture body 510 and the light source unit 520 are shown in FIGS. 10(a) and 10(b), respectively.

[0054] <Fixture body> The fixture body 510 includes a box-shaped fixture body housing 515 with an open bottom surface, a spring receiver 511, and a connector 512.

[0055] <Light source unit> The light source unit 520 includes a mounting portion 521, a substrate 522, a light source 523, a cover 524, a power supply case 525C, a wireless module 526, a wireless switch 534, a mounting spring 527, and a connector 528. A plurality of light source units 520 can be arranged such that the cover end faces face each other, and the entire plurality of light source units 520 can be made into a continuous long light source. Note that not only the cover 524 that constitutes the outside of the light source unit but also the mounting portion 521 and the power supply case 525C that house the power supply 525 that appear outside when the light source unit and the fixture body are removed or in a temporarily fixed state are also referred to as the outer contour portion 501 of the light source unit.

[0056] The substrate 522 is a long printed circuit board, and a plurality of light sources 523 composed of surface-mounted LEDs are arranged in a row at intervals in the longitudinal direction. The number of rows of the light sources 523 is one row.

[0057] The mounting spring 527 of the light source unit 520 is attached to the spring receiver 511 of the appliance body 510. At this time, there are two possible mounting states: a state where the appliance body 510 and the light source unit 520 are mounted without a gap (the state shown in FIG. 9), and a temporary fixing state where a gap is formed between the appliance body 510 and the light source unit 520. By pulling down the light source unit 520 downward, the temporary fixing state can be easily achieved. In the temporary fixing state, the connector 528 of the light source unit 520 can be connected to the connector 512 of the appliance body 510. Also, in the temporary fixing state, the wireless switch 534 can be operated.

[0058] The power supply 525 converts commercial AC power into a drive output. The drive output can be controlled by an external control signal. In this embodiment, the control signal is transmitted wirelessly and received by the wireless module 526. The wireless module 526 sends the control signal to the power supply 525, and the power supply 525 is controlled. Here, the wireless switch 534 can turn off the wireless control function. In that case, the light source unit 520 is controlled by preset default lighting control conditions.

[0059] <Modification Example> As described above, the embodiments of the lighting device according to the present invention have been explained. However, it is possible to modify the illustrated lighting device as follows, for example, and it goes without saying that the present invention is not limited to the lighting device as shown in the above embodiments.

[0060] The outer shell part of the lighting device mainly refers to a single or multiple box-like structures that house the lighting device body and the power supply. When the lighting device consists of multiple components such as a lamp body and a power supply, each has an outer shell part. The arms and mounting parts that make up the lighting device also constitute the outer shell part. Therefore, the wireless switch may be provided on the arm or the mounting part. Components not covered by a case such as the heat sink 320 can have their surfaces regarded as the outer shell part.

[0061] There may be a wireless switch in a power supply case or the like, which is a part installed in the ceiling space like a ceiling-embedded downlight. Since the ceiling-embedded downlight is only attached to the ceiling recess hole with a spring, it can be easily removed from the ceiling by pulling the downlight downward, and the wireless switch can be operated in this state.

[0062] The form of the lighting control signal transmitted by the signal line 142S is not particularly limited, and in addition to the exemplified PWM signal, it can be a digital signal or the like. In the case of a PWM signal, it is common to use two signal lines to control two-color LEDs and three signal lines to control three-color LEDs. However, in the case of a digital signal, a plurality of signals can be sent through one signal line.

[0063] As an example of the wireless communicator, a wireless module detachable from the appliance body has been shown, but the detachment is not essential. Also, the module does not have to be integrated. That is, components such as an antenna, a transmitter, an encoder, a receiver, and an encoder that constitute the wireless communicator may be separated.

[0064] To prevent incorrect operation of the wireless switch by users other than the setter, an adhesive sticker may be attached to the wireless switch or it may be covered with a plate.

[0065] In Embodiment 3, the case where the power supply and the wireless communicator are provided in the light source unit has been described, but these may be provided in the appliance body.

[0066] Note that the above-described embodiments disclosed this time are illustrative in all respects and are not a basis for a limiting interpretation. Therefore, the technical scope of the present invention is not interpreted only by the above-described embodiments, but is defined based on the description of the claims. Also, all changes within the meaning and scope equivalent to the claims are included.
