[Figure 10] 3 is a cross-sectional view of a lighting device according to a third embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0016] <Embodiment 1> <Configuration> FIG. 1 shows a perspective view of a lighting device 100 according to this embodiment. The lighting device 100 is a spotlight that can be attached to a wiring duct 180. As shown in FIG. 4, which is a partial side view and partial cross-sectional view, the lighting device 100 is equipped with light sources 130, which collectively refer to one-color light source 130N, two-color light source 130T, and three-color light source 130S. The lighting device 100 may be a dimmable lighting device 100A equipped with one-color light source 130N, a lighting device 100B equipped with two-color light source 130T that can change color temperature and be dimmed, or a lighting device 100C equipped with three-color light source 130S that can change chromaticity and be dimmed.

[0017] In the following explanation, the terms F direction, B direction, U direction, and D direction will be used, based on the axis AX in Figure 1. The direction perpendicular to the axis AX and the up-down direction will sometimes be referred to as left and right.

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

[0019] The axis AX, which is the direction of the lighting device 100, can be rotated horizontally by rotating the arm 170 in the Φ direction relative to the mounting portion 178. Ruθ The rotation of the direction allows the orientation to be changed from downward to upward as appropriate.

[0020] 2, which is a rear view of the lamp body of the lighting device 100, a wireless switch 144 is attached to the lamp body rear surface 111, and a mark 144M is printed on it to indicate whether the wireless control function is on or off. The wireless control function can be switched on or off by moving a wireless switch slider 144S, which corresponds to the knob of the wireless switch 144.

[0021] When a lighting device installer or other setter turns on the wireless switch 144, the wireless control function of the lighting device 100 is turned on, and the light intensity and lighting color can be controlled via wireless communication from a lighting control device 190, which is made up of a tablet, smartphone, PC, or remote control. Hereinafter, control of light intensity will be referred to as dimming, and control of lighting color will be referred to as color adjustment. When the wireless switch 144 is turned off, the wireless control function of the lighting device 100 is turned off, and the lighting device 100 operates at a predetermined dimming rate (for example, 100% dimming rate).

[0022] As another example of a rear view of the luminaire of the lighting device 100, FIGS. 3(a) and (b) show the cases when the wireless control is on and off, respectively. A wireless switch 144 is attached to the rear surface 111 of the luminaire. To enable the operator to distinguish whether the wireless control function is on or off, a lower switch portion 144P is visible when the wireless control function is on, and a lower switch portion 144Q is visible when the wireless control function is off. The color of the lower switch portion 144P is preferably different from the color of the lower switch portion 144Q, and the color of the lower switch portion 144P is preferably different from the color of the wireless switch slider 144S (knob portion). On the other hand, the color of the lower switch portion 144Q is preferably the same as the color of the wireless switch slider 144S. For example, the color of the lower switch portion 144P is green, and the colors of the lower switch portion 144Q and the wireless switch slider 144S are black. This allows the operator to distinguish whether the wireless control is on or off. This allows the operator to distinguish whether the wireless control is on or off without printing a mark 114M. If the mark 144M is not displayed, it is difficult for users other than the person who set it up to know whether the wireless control is on or off, which has the advantage that users will not operate the wireless switch inadvertently.

[0023] Fig. 4 is a partial side view and partial cross-sectional view including the axis AX of the lighting body 110. Inside the lighting body 110, there are provided a heat sink 120, a light source 130, a reflector 132, a lens 134, a power supply 140, a wireless module signal cable 142, a wireless module socket 146, and a wireless module 148 which is a wireless communication device, as well as the parts that will be described in Fig. 5. The wireless module 148 is detachable from the wireless module socket 146.

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

[0025] <Wiring diagram around the wireless switch> 5 shows a conceptual diagram of a circuit including the wireless switch 144 of the lighting device 100. The wireless module 148 functions as a wireless transmitter / receiver and has a built-in antenna. The wireless module socket 146 is a socket to which the terminals of the wireless module 148 are connected.

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

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

[0028] IC 141A of power supply 140 supplies LED drive output controlled based on the lighting control signal to light source 130 via drive cable 135. When using LEDs of one color, drive cable 135 consists of drive line 135A and ground line 135G, but when, for example, LEDs of three colors are driven independently, drive lines 135A, 135B, and 135C and ground line 135G are used.

[0029] As described above, circuit 141B is used to set the default lighting control conditions when wireless switch 144 is off, but memory 141M storing preset default lighting control conditions may also be used in circuit 141B in Fig. 5, for example. Memory 141M can be used particularly preferably when there are multiple default lighting conditions, as will be described later.

[0030] <Operation control> The lighting control device 190 shown in Fig. 1 can adjust the brightness and color of the lighting device 100 and perform scheduled operation. Scheduled operation can turn the light on when the store opens or when the shift starts, and off when the store closes or when the shift ends. If the lighting device 100 is capable of adjusting brightness and color, it can change the lighting according to the time of day to suit human biorhythms, for example, by setting a color temperature of 6500K and a dimming rate of 100% in the morning and a lower color temperature of 2700K and a dimming rate of 60% in the evening.

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

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

[0033] <Advantage 1 of wireless switches> If a lighting device without wireless control function is used instead of a lighting device with a wireless switch, the problems of setting up a lighting device that can be controlled and the problems of using radio frequency bands do not occur. Compared to such lighting devices, the advantages of a lighting device with a wireless switch are as follows:

[0034] If a problem occurs with wireless control, you can disable the wireless control function temporarily or for only some devices.

[0035] If wireless control is required in the future, it can be done simply by flipping the wireless switch, so there is no need to replace the lighting equipment.

[0036] <Advantage 2 of wireless switches> For example, even if the wireless module 148 is removed from the wireless module socket 146 without using the wireless switch 144, the same effect can be obtained as if the wireless switch 144 were turned off. In contrast, the advantages of a lighting device with a wireless switch include the following.

[0037] Since the wireless module 148 is installed inside the lighting body 110, it cannot be removed unless, for example, a screw on the back surface 111 of the lighting body is removed. However, by using the wireless switch 144, it is not necessary to disassemble the lighting body.

[0038] When the wireless module 148 is removed, it needs to be stored properly and there is a risk of losing it. However, by using the wireless switch 144, there is no need to store it and there is no risk of losing it. The wireless switch 144 can be used to immediately return to a wirelessly controllable state.

[0039] <Advantage 3 of wireless switches> For example, compared to a dimmer or its wireless equivalent, a lighting control device, which has an ON / OFF switch, the advantages of a lighting device with a wireless switch are as follows:

[0040] By turning the wireless control function of a lighting device on and off using a wireless switch that is equipped on the lighting device itself, you can intuitively recognize which lighting device's wireless control function you want to turn off.

[0041] Since lighting devices are usually installed on the ceiling, the wireless switch provided on the lighting device 100 cannot be inadvertently operated by a user who is simply present in the room.

[0042] <Modification of the installation position of the wireless switch> There is no particular limitation on the installation position of the wireless switch 144. For example, it may be installed at a position on the upper side of the lamp body side surface 112, as shown as wireless switch 144B in FIG.

[0043] <Modification 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, 70-100 indicated by the mark 144M2 corresponds to a dimming rate of 70%-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, 4200·3500·3000 indicated by the mark 144M3 corresponds to color temperatures of 4200K·3500K·3000K) when the wireless control function is turned off.

[0044] As explained above, the same effect can be achieved by removing the wireless module 148 instead of turning the wireless switch 144 on and off, but 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 multiple preset lighting control conditions.

[0045] Wireless switch 144C and wireless switch 144D are switches that turn the wireless on and off and select the default lighting control conditions, but it is also possible to provide another switch that selects the default lighting control conditions and that is activated when the wireless switch is turned off, separate from the wireless switch.

[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 a ceiling 395.

[0047] Fig. 7 is a perspective view of lighting device 300. In Fig. 7, lighting device 300 comprises a lamp body 310 and a power supply case 372, which are connected to each other by an arm 370 so as to be rotatable in the horizontal and vertical directions. The lamp body 310, arm 370, and the outer casing of power supply case 372 will collectively be referred to as outer casing 301 of lighting device 300.

[0048] The lamp body 310 is provided with a heat sink 320, a light source 330 mounted on the heat sink 320, and a lens 334.

[0049] Power supply 340 is installed inside power supply case 372, which is provided with a front mounting portion 376 for connecting to wiring duct 380, a lever 375 for moving the front mounting portion, and a rear mounting portion 378, and commercial power is input to power supply 340 from front mounting portion 376.

[0050] 8, which shows the back of power supply case 372, wireless module 348 and wireless switch 344 are provided on the back of power supply case 372, and mark 344M is printed on it to indicate whether the wireless control function is on or off. The wireless control function can be switched on or off by moving wireless switch slider 344S.

[0051] Referring to Fig. 5, power supply 340 has a function of converting power supplied from a commercial power source (corresponding to power line 138 in Fig. 4) into a drive output for light source 330. To control the drive output, power supply 340 is provided with a wireless module socket 346. Wireless module 348 receives a wireless control signal addressed to itself sent from lighting control device 390, and transmits the lighting control signal included in the wireless control signal to power supply 340. Here, when wireless switch 344 is turned off, no power is supplied to wireless module 348, and therefore the lighting control signal is not transmitted to power supply 340. In this case, power supply 340 supplies a drive output of preset lighting control conditions to light source 330.

[0052] <Embodiment 3> <Summary> 9 shows a perspective view of the lighting device 300 according to this embodiment. The lighting device 500 comprises a fixture body 510 directly attached to the ceiling and a light source unit 520 attached to the fixture body 510, and the light source unit 520 can be attached, detached, or temporarily fixed to the fixture body 510. Because the fixture body 510 and the light source unit 520 are attachable and detachable, the screws or hanging bolts for attaching the fixture body 510 to the ceiling, as well as the power supply case 525C and wiring on the top surface of the light source unit 520, can be hidden. The lighting device has a width of 2 cm and a length of 120 cm, for example, and its shape is designed with design in mind.

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

[0055] <Light source unit> The light source unit 520 includes an attachment portion 521, a circuit board 522, a light source 523, a cover 524, a power supply case 525C, a wireless module 526, a wireless switch 534, an attachment spring 527, and a connector 528. By arranging a plurality of light source units 520 with the cover end faces facing each other, the plurality of light source units 520 can all be configured as a continuous, long light source. Note that not only the cover 524 that forms the exterior of the light source unit, but also the attachment portion 521 that appears outside when the light source unit and the fixture body are removed or temporarily fastened, and the power supply case 525C that houses the power supply 525 are hereinafter referred to as the outer casing 501 of the light source unit.

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

[0057] The mounting spring 527 of the light source unit 520 is attached to the spring receiver 511 of the fixture body 510. At this time, the fixture body 510 and the light source unit 520 can be attached in an attached state (the state shown in FIG. 9) with no gap between them, or in a temporarily attached state with a gap between them. The temporarily attached state can be easily achieved by holding the light source unit 520 and pulling it downward. In the temporarily attached state, the connector 528 of the light source unit 520 can be connected to the connector 512 of the fixture body 510. Furthermore, in the temporarily attached state, the wireless switch 534 can be operated.

[0058] The power supply 525 converts commercial AC power into a driving output. The driving 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, which then sends the control signal to the power supply 525, thereby controlling the power supply 525. Here, the wireless control function can be turned off by the wireless switch 534, in which case the light source unit 520 is controlled under preset lighting control conditions. Osa can be.

[0059] <Modification> The above describes an embodiment of the lighting device according to the present invention. However, the exemplified lighting device can be modified, for example, as follows, and it goes without saying that the present invention is not limited to the lighting device as shown in the above embodiment.

[0060] The outer casing of a lighting device is primarily a single or multiple boxes that house the lighting device body and power supply. If the lighting device is made up of multiple components, such as a lamp body and a power supply, each of these components has its own outer casing. The arms and mounting parts that make up the lighting device also constitute the outer casing. Therefore, the wireless switch may be provided on the arms or mounting parts. For components that are not covered by a case, such as the heat sink 320, their surfaces can be considered to be the outer casing.

[0061] A wireless switch may be provided in the power supply case, which is the part installed above the ceiling, as in the case of a recessed ceiling downlight. A recessed ceiling downlight is simply attached to a recessed hole in the ceiling with a spring, so it can be easily removed from the ceiling by pulling the downlight downward, and the wireless switch can be operated in that state.

[0062] The format of the lighting control signal transmitted over signal line 142S is not particularly limited, and can be a PWM signal as exemplified, as well as a digital signal, etc. In the case of a PWM signal, two signal lines are generally used to control two-color LEDs, and three signal lines are generally used to control three-color LEDs, but in the case of a digital signal, multiple signals can be sent over a single signal line.

[0063] Although an example of a wireless module that can be attached to and detached from the device body has been shown as the wireless communication device, detachment is not essential. Furthermore, the wireless communication device does not have to be a single module. In other words, the components that make up the wireless communication device, such as the antenna, transmitter, encoder, receiver, and encoder, may be separate.

[0064] To prevent erroneous operation of the wireless switch by users other than the person who set it up, an adhesive sticker may be placed on the wireless switch or the switch may be covered with a board.

[0065] In the third embodiment, the case where the power supply and the wireless communication device are provided in the light source unit has been described, but these may also be provided in the fixture body.

[0066] It should be noted that the above-described embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present invention should not be interpreted solely by the above-described embodiments, but should be defined by the claims. Furthermore, all modifications within the scope and meaning equivalent to the claims are included. [Explanation of symbols]
