Description

  The present invention relates to an illuminating device using an LED element as a light source, and particularly senses information necessary for controlling the illuminating device in a ceiling-mounted ceiling light connected to a wiring fixture installed on a ceiling surface. The present invention relates to improvement of the sensor unit.

  2. Description of the Related Art In recent years, due to an increase in environmental awareness, a self-powered light bulb type LED lamp using an LED element excellent in power saving as a light source has been widespread. Furthermore, recently, lighting devices using LED elements have been developed and introduced into the market for ceiling-mounted ceiling lights and hanging lighting devices that are suspended from the ceiling and illuminate the interior of the room.

  As such a ceiling-mounted ceiling light, it has recently been desired to provide a ceiling light with a small thickness. In this case, such a lighting device is mounted on a wiring device such as a hooking rosette attached to the ceiling surface with a thread blade integrally formed with an adapter (for example, see Patent Document 1).

  Specifically, the lighting fixture described in Patent Document 1 includes a blade, an adapter provided with a blade, a power circuit, a board on which an LED is mounted, a blade, an adapter, a power circuit, and a board. And the blade has a hooking claw that is hooked and fixed to a hooking ceiling fixed to the ceiling, and the adapter is connected to the blade and is electrically connected to supply power to the power supply circuit. The power supply circuit includes a connection terminal that supplies power to the substrate by being coupled to a connection pin provided on the substrate. Thereby, while being able to make it still thinner, the lighting fixture which can aim at reduction of an assembly man-hour and cost reduction is provided.

  However, because the power supply circuit and the board on which the LED is mounted are configured separately as in the lighting fixture of Patent Document 1, the number of parts and assembly man-hours increases, and the power supply circuit and the board are coupled to the conductive portion and the connection pin. Therefore, there are problems that the number of parts and assembly man-hours increase accordingly, and the lighting apparatus can be reduced in size and thickness, but the cost reduction cannot be accurately met.

  A human sensor that detects whether or not a person is present, a plurality of light sources that surround the human sensor and are arranged at approximately equal distances from a predetermined center position; A cylindrical partition that extends from the edge of the opening to the inside of the cover and surrounds the side surface of the human sensor that penetrates the opening. There is provided a luminaire including a light source module provided with a light source. (For example, refer to Patent Document 2). Thereby, the detection range of the human sensor and the entire irradiation range obtained by combining the irradiation ranges of the plurality of light sources can be matched, and a 360-degree uniform light distribution can be realized as a whole.

  However, in the luminaire of Patent Document 2, in order to block the light from the light source by providing a cylindrical partition wall extending from the edge of the opening of the cover to the inside of the cover and surrounding the side surface of the human sensor. In addition, the partition walls need to be made of a colored resin, which may complicate the cover creation process.

  Furthermore, in each of the illumination devices described in the cited documents 1 and 2, since the translucent cover is attached to the outer peripheral portion of the instrument main body, the shape and size of the translucent cover attached from the attachment position. As a result, multiple types of translucent covers with different tastes cannot be easily attached to a single-shaped instrument body, and it is difficult to reduce costs by sharing parts. There was a problem that there was.

As shown in FIGS. 9 and 10, the substrate 15 is configured by mounting a sensor portion 17 in which a plurality of sensors are incorporated at the center of the upper surface of the substrate 15 (the direction of emitted light from the LED element 15 e). This board | substrate 15 consists of a glass composite board | substrate (CEM-3) wired on both surfaces, and is a substantially disc shape as shown in FIG. 11 thru | or FIG. At the time of assembly, the blade connection hole 15 g of the substrate 15 and the blade terminal portion 12 e of the hooking blade 12 are fitted, and external power is input to the substrate 15. In this case, in the present invention, as shown in FIGS. 9 to 12, the LED element 15 e and the circuit component 15 f constituting the lighting circuit are mounted or mounted on the same substrate 15. That is, the circuit component 15f constituting the lighting circuit is mounted on the same board 15 as the board 15 on which the LED element 15e is mounted, and the board for the LED element 15e and the board for the lighting circuit are not provided separately. Since the LED element 15e and the lighting circuit are provided on the same single substrate 15, there is no need for a separate device for connecting the LED element 15e to the lighting circuit, thereby achieving further reduction in thickness and size. In addition, since a plurality of substrates are not required, the cost can be reduced.

  In this case, as shown in FIGS. 11 and 14, the substrate 15 is divided into a plurality of areas, and each area has a different function. In addition, the plurality of areas are not set only on one surface of the substrate 15, but are set on the front surface and the back surface of the substrate 15 as shown in FIGS. In the form, a total of five areas are set, with three areas on the front surface (surface arranged toward the floor) and two areas on the back surface (surface arranged toward the ceiling surface and other mounting surfaces). Yes.

  More specifically, as shown in FIGS. 11 to 14, the substrate 15 has an LED element 15 e, a circuit component 15 f, and a sensor unit 17, so that the front surface and the back surface are respectively outside from the inside (center side). It is divided into a plurality of areas in a substantially annular shape toward the (outer peripheral side). For each area, an LED element 15e, a circuit component 15f for a lighting circuit for lighting the LED element 15e, and a sensor unit 17 on which a plurality of sensors are mounted are mounted. In this case, for example, as shown in FIG. 13, the front surface from which light is emitted includes an LED element mounting area 15 a for mounting the LED element 15 e on the substrate 15 on the outer peripheral side, and an LED from the outer peripheral side toward the center side. A circuit component mounting area 15c for mounting the circuit component 15f of the lighting circuit inside the element mounting area 15a, and a sensor for mounting the sensor unit 17 inside the circuit component mounting area 15c from the outer peripheral side toward the center side. A mounting area 15b and a circuit component mixed area 15c for mounting the circuit component 15f of the lighting circuit divided on the center side are configured. As shown in FIG. 14, the back surface of the substrate 15 to be brought into contact with the heat radiating contact portion 14b of the heat radiating member 14 is a heat radiating area 15d where the outer peripheral side is brought into contact with the heat radiating contact portion 14b, and the circuit component 15f of the lighting circuit is mounted at the center side. Circuit component mounting area 15c for this purpose.

  In this way, the substrate 15 on which the LED element 15e, the circuit component 15f, and the sensor unit 17 are installed is divided into a plurality of areas. For each of these areas, for example, mounting of the LED element 15e, heat dissipation, and circuit component 15f Since different functions such as mounting and mounting of the sensor unit 17 are shared, the LED element 15e, the circuit component 15f, and the sensor unit 17 are arranged on the same substrate 15 to sufficiently reduce the thickness and cost. Even if the LED element 15e, the circuit component 15f, and the sensor unit 17 are arranged on the same substrate 15, the thermal interference between the LED element 15e and the circuit component 15f can be suppressed and the LED element 15e in each area. In addition, it is possible to effectively dissipate heat generated from the circuit components 15f and prevent light extraction efficiency from being lowered due to heat generation.

  In this case, since the plurality of areas of the substrate 15 are set on the front surface and the back surface of the substrate 15 at the same time, the functions are efficiently shared by the single substrate 15, and each area is more effectively It is possible to suppress the mutual interference of the electronic components mounted on the circuit board and to effectively dissipate the heat generated by the circuit components. As the circuit component 15f constituting the lighting circuit, known circuit components such as various diodes, coils, capacitors, ICs, resistors, etc. for performing overcurrent protection, noise cut, rectification, smoothing, dimming control, etc. are used. can do.

(4-1 Component placement)
The arrangement of the electronic components in each area of the substrate 15 will be described in more detail. First, in the LED element mounting area 15a located on the outer peripheral portion side of the surface of the substrate 15, as shown in FIGS. The LED elements 15e are mounted in an annular shape at substantially equal intervals. As shown in FIGS. 10 and 12, a heat dissipation area 15d is set on the back surface corresponding to the LED element mounting area 15a. The heat dissipation area 15d is not provided with circuit wiring, and is a heat dissipation contact portion of the heat dissipation member 14. The heat generation from the LED element 15e can be efficiently radiated from the heat radiation member 14 via the heat radiation area 15d on the back surface of the substrate 15.

  On the other hand, in the substantially annular circuit component mounting area 15c located on the center side of the LED element mounting area 15a on the surface of the substrate 15, as shown in FIGS. 12 and 13, a chip which is a short circuit component 15f is provided. Uniform light is emitted from the entire surface on the front surface (floor surface side) together with the surface mountable circuit component 15f such as the fixed resistor 151j having a shape and the coil 151a and the LED element mounting area 15a located on the outer peripheral side. As described above, the LED element 15e is mounted. The reason why the short circuit component 15f is mounted in the circuit component mounting area 15c is to prevent the light emitted from the LED element 15e from being obstructed by the circuit component 15f.

  Next, as shown in FIG. 13, the blade terminal portion 12e of the hooking blade 12 is inserted into the substantially annular sensor mounting area 15b positioned on the center side of the circuit component mounting area 15c on the surface of the substrate 15. The blade connection hole 15g and the reflection cylinder fixing hole 15k into which the fixing leg 173f of the reflection cylinder 17c is inserted and fixed are arranged. Since the substantially cylindrical reflecting cylinder 17c is mounted on the surface of the substrate 15, the light emitted from the LED element 15e is blocked by the reflecting cylinder 17c, so that the surface of the reflecting cylinder 17c irradiated with the emitted light is reflected. It is created so as to have a light reflecting function using a material, a reflection sheet, or the like.

  In the substantially circular circuit component mounting area 15c on the center side of the surface of the substrate 15, as shown in FIG. 13, surface mounting such as a chip-shaped fixed resistor 151j and a bridge diode 151b, which are short circuit components 15f, are provided. A connector 15m for wiring between the corresponding circuit component 15f and the sensor substrate 17b is disposed. Since the circuit component mounting area 15c is a portion covered with the reflection cylinder 17c constituting the sensor unit 17, since the heat dissipation condition is not good, it is necessary to consider the circuit component 15f that generates less heat.

  The circuit component mounting area 15c on the back surface corresponding to the circuit component mounting area 15c corresponds to the position of the heat radiation opening 14a of the heat radiation member 14 as shown in FIGS. Discrete circuit components such as IC, 151c, electrolytic capacitor 151d, choke coil 151e, capacitor 151f, fuse 151g, and film capacitor 151h, which are circuit components 15f that are taller than the mounted circuit component 15f, are mounted. In addition, a space in which the circuit component 15f can be inserted is provided in the central portion on the base member 10 side facing the circuit component mounting area 15c.

Further, in the circuit component 15f of the lighting circuit, for example, a heat conducting member made of silicon or the like having elastic characteristics is arranged on the substrate surface in the IC 151c or the like where the component is tall and generates heat, and then fixed to the substrate 15. Is desirable. As a result, the heat generated by the circuit component 15f can be radiated to the substrate 15 via the heat conducting member, and the heat radiation efficiency of the lighting circuit can be increased to suppress thermal interference. Further, when silicon is used as the heat conducting member, it has good heat dissipation and insulation, and is excellent in heat resistance and long-term reliability.
Furthermore, in order to increase the light extraction efficiency of the LED element 15e, further light is applied by bonding a highly reflective sheet or applying a highly reflective resin to the substrate 15 on the LED element mounting surface side of the LED element 15e. The extraction efficiency can be improved.

  In addition, as LED element 15e mounted on this board | substrate 15, various well-known LED can be used. In the present embodiment, two types of LED illumination devices 100 are configured using a high-luminance type LED element that emits white light for illumination or a high-luminance type LED element that emits light bulb color.
