Description

  The present invention relates to a lighting device.

  In recent years, lighting devices using LEDs (Light Emitting Diodes) have become widespread. 2. Description of the Related Art Conventionally, as this type of lighting device, a long LED illumination including a long casing and a plurality of LED modules arranged linearly in the casing is known (for example, Patent Document 1). .

  In order to realize long LED lighting, a technique for connecting a plurality of long lighting units in which light sources are housed in a straight line has also been proposed (for example, Patent Document 2).

JP 2012-84367 A JP 2009-99363 A

  When a plurality of lighting units in which light sources are stored are connected in a straight line, not only two adjacent lighting units are electrically connected but also mechanically connected in some cases.

  In this case, for example, a male connector is provided at one end in the longitudinal direction of the illumination unit and a female connector is provided at the other end, and the male connector of one illumination unit of the two illumination units and the other illumination are provided. It is conceivable to connect the two lighting units electrically and mechanically by connecting the female connector of the unit. That is, a structure for mechanically connecting the two lighting units is provided in the male connector and the female connector for electrical connection.

  However, when a structure for mechanically connecting the two lighting units is provided in the male connector and the female connector for electrical connection, a gap is generated in the male connector and the female connector, and the inside of the lighting unit is formed from this gap. There is a risk that insects and dust may enter. As a result, there is a possibility that a conductive portion such as a wiring may be short-circuited or an electronic component may be deteriorated due to insects or dust that have entered the lighting unit. Moreover, there is a possibility that the appearance of the lighting unit may be deteriorated by the dead carcasses (black particles) that have entered.

  In particular, when an LED is used as a light source, since the insect is attracted to the wavelength of light emitted from the LED, the insect is likely to enter the lighting unit. Moreover, since the LED has a long life and does not require replacement of the light source for a long period of time, insects and dust tend to accumulate in the lighting unit.

  The present invention has been made in order to solve such a problem, and when connecting a plurality of lighting units, a plurality of insects and dust are prevented from entering a region where a light source is arranged. It is an object of the present invention to provide an illumination device that can easily perform electrical and mechanical connection of the illumination unit.

  In order to achieve the above object, an aspect of the illumination device according to the present invention includes a long illumination unit that houses a light source and has a light-transmitting portion that transmits light from the light source, and a longitudinal direction of the illumination unit. A first connecting portion and a second connecting portion provided at one end of the lighting unit, and a first connected portion and a second connected portion provided at the other end in the longitudinal direction of the illumination unit. The lighting unit includes a first housing region and a second housing region which are divided in the width direction of the lighting unit with a partition wall therebetween, and the light source is provided in the first housing region. And each of the first connecting portion and the first connected portion has a structure capable of being electrically connected to each other, and in the side view from the longitudinal direction of the lighting unit, 1 in a position overlapping with the housing area of 1, The two connecting portions and the second connected portion have a structure that can be mechanically connected to each other, and are in a position overlapping the second housing region in a side view from the longitudinal direction of the lighting unit.

  Hereinafter, each component of the illuminating device 1 which concerns on this Embodiment is demonstrated in detail using FIGS. 1-4.

[Light emitting module]
The light emitting module 110 is an example of a light source unit of the illumination unit 100 and emits white light, for example. In the present embodiment, the light emitting module 110 is an LED module configured by LEDs. Note that the light emission color of the light emitting module 110 is not limited to white light.

  The light emitting module 110 is housed in the lighting unit 100. Specifically, the light emitting module 110 is housed in the housing 120. The light of the light emitting module 110 passes through the light transmitting portion 121a of the housing 120 and is emitted to the outside of the housing 120 as illumination light.

  As shown in FIGS. 3 and 4, the light emitting module 110 includes a substrate 111, a light emitting element 112, a first connection terminal 113, a second connection terminal 114, and a circuit element 115.

  The substrate 111 is a long plate member whose longitudinal direction is the Y-axis direction. The substrate 111 is, for example, a resin substrate, a ceramic substrate, a metal base substrate, or the like. Note that the substrate 111 is not limited to a rigid substrate, and may be a flexible substrate or a film substrate.

  A plurality of light emitting elements 112 are arranged on the substrate 111. Each of the plurality of light emitting elements 112 is a light source of the lighting device 1 and is housed in the lighting unit 100. Specifically, the light emitting element 112 is housed in the housing 120. Each light emitting element 112 emits light by DC power supplied from the circuit element 115 constituting the power supply circuit.

  As shown in FIG. 3, the plurality of light emitting elements 112 are arranged in a line on the substrate 111 along the longitudinal direction of the substrate 111. The plurality of light emitting elements 112 arranged in a line function as a line light source that emits light in a line.

  In the present embodiment, each light emitting element 112 is an LED light source composed of LEDs. Specifically, each light emitting element 112 is an SMD type LED element in which an LED chip is packaged, and is a resin or ceramic white container having a recess and a primary mounting 1 on the bottom surface of the recess of the container. It has one or more LED chips and a sealing member sealed in the recess of the container. The sealing member is made of a translucent resin material such as silicone resin. The sealing member may be a phosphor-containing resin containing a wavelength conversion material such as a phosphor.

  The LED chip is an example of a semiconductor light emitting element that emits light with a predetermined DC power, and is a bare chip that emits monochromatic visible light. The LED chip is, for example, a blue LED chip that emits blue light when energized. In this case, in order to obtain white light, the sealing member contains a yellow phosphor such as YAG (yttrium, aluminum, garnet) that emits fluorescence using blue light from the blue LED chip as excitation light.

  Thus, the light emitting element 112 in this Embodiment is a white LED light source comprised by the blue LED chip and the yellow fluorescent substance. Specifically, the yellow phosphor absorbs a part of the blue light emitted from the blue LED chip and is excited to emit yellow light, and the yellow light and the blue light not absorbed by the yellow phosphor are mixed. White light. The sealing member is not limited to the yellow phosphor, and may include a red phosphor and a green phosphor.

  A first connecting terminal 113 and a second connecting terminal 114 are arranged on the substrate 111. The first connection terminal 113 is disposed at one end portion in the longitudinal direction of the substrate 111, and the second connection terminal 114 is disposed at the other end portion in the longitudinal direction of the substrate 111. Each of the first connection terminal 113 and the second connection terminal 114 is a pair of connector terminals to which an electric wire such as a lead wire is connected, for example, a quick connection terminal.

  The first connection terminal 113 is an input side terminal to which electric power is input from the outside of the light emitting module 110. That is, the first connection terminal 113 is a power receiving terminal that receives power from the outside of the light emitting module 110. The first connection terminal 113 is electrically connected to the first connection part 210 by a lead wire (not shown) or the like, and the first connection terminal 113 is input to the first connection part 210. Power is input. For example, AC power from a commercial power source is input to the first connection terminal 113 via the first coupling unit 210.

  The second connection terminal 114 is an output side terminal that outputs electric power to the outside of the light emitting module 110. That is, the second connection terminal 114 is a power transmission terminal that transmits power to the outside of the light emitting module 110. The second connection terminal 114 is electrically connected to the first coupled portion 310 by a lead wire (not shown) or the like, and is externally connected from the second connection terminal 114 via the first coupled portion 310. Power is output.

  The first connection terminal 113 and the second connection terminal 114 are electrically connected by a feed wiring (not shown). The feed wiring is, for example, a pair of metal wirings and is formed as a pattern wiring of the substrate 111. As an example, the pair of feed wirings are two metal wirings formed in parallel, and both ends thereof are connected to the pair of first connection terminals 113 and the pair of second connection terminals 114. The feed wiring is composed of only metal wiring, and the first connection terminal 113 and the second connection terminal 114 have the same potential except for the resistance component of the feed wiring. As a result, the AC power input to the first connection terminal 113 is supplied to the second connection terminal 114 through the feed wiring (AC feed wiring) with the AC waveform as it is without changing the frequency and amplitude. . For example, when AC 100V AC power is supplied to the first connection terminal 113, AC 100V AC power is supplied to the second connection terminal 114 as it is. Therefore, in this case, the second connection terminal 114 transmits AC 100V AC power to the outside of the light emitting module 110. Thereby, transmission of AC power from the first connecting unit 210 to the second connecting unit 220 is realized.

  Further, the AC power input to the first connection terminal 113 is also supplied to the power supply circuit configured by the plurality of circuit elements 115. For example, when AC 100V AC power is supplied to the first connection terminal 113, AC 100V AC power is supplied to the power supply circuit. That is, the first connection terminal 113 also functions as a power supply terminal that supplies AC power to the power supply circuit.

  As described above, in the light emitting module 110 according to the present embodiment, when AC power is supplied to the first connection terminal 113, AC power is supplied to the second connection terminal 114 through the feed wiring, and a plurality of the power is supplied. AC power is also supplied to the power supply circuit constituted by the circuit element 115.

  The plurality of circuit elements 115 are arranged along the longitudinal direction of the substrate 111. The plurality of circuit elements 115 are arranged in parallel with the element rows of the plurality of light emitting elements 112. That is, the plurality of circuit elements 115 are arranged side by side with the plurality of light emitting elements 112.

  The plurality of circuit elements 115 include electronic components that constitute a power supply circuit (power supply) that generates power for causing the plurality of light emitting elements 112 to emit light. The electric power generated by the plurality of circuit elements 115 constituting the power supply circuit is supplied to each of the plurality of light emitting elements 112 via the pattern wiring formed on the substrate 111.

  In the present embodiment, since the light emitting module 110 is driven by an AC direct method, AC power is supplied to the first connection terminal 113. In this case, the plurality of circuit elements 115 included in the power supply circuit convert AC power supplied to the first connection terminal 113 into DC power for causing the light emitting element 112 to emit light. Therefore, the plurality of circuit elements 115 include, for example, a rectifying element that rectifies an AC voltage and converts it into a DC rectified voltage, and the plurality of light emitting elements 112 emit light according to the rectified voltage. The plurality of circuit elements 115 constituting the power supply circuit include, for example, a capacitor element such as an electrolytic capacitor or a ceramic capacitor, a resistor element such as a resistor, a rectifier element, a fuse, a noise filter, a diode, a switching element, or an integrated circuit element. These are semiconductor elements.

  The plurality of circuit elements 115 may include elements that do not constitute a power supply circuit. For example, the plurality of circuit elements 115 may include a control circuit element for controlling the light emission state of the light emitting element 112 or a communication circuit element for performing communication with other devices.

[Case]
As shown in FIGS. 1 to 4, the casing 120 is an outer casing that forms an outer casing of the lighting unit 100, and houses the light emitting module 110. Specifically, the housing 120 has a substantially rectangular tube shape whose longitudinal direction is the Y-axis direction.

  As shown in FIGS. 3 and 4, the housing 120 includes a long cover 121 and a long base 122 facing the cover 121. The cover 121 is an upper cover that covers the front side (the light emitting element 112 side) of the light emitting module 110, and the base 122 is a lower cover that covers the back side of the light emitting module 110.

  The cover 121 includes a light transmitting portion 121 a that covers the plurality of light emitting elements 112, a light shielding portion 121 b that covers the plurality of circuit elements 115, and a flange portion 121 c that protrudes in the shape of a flange on the outer side in the width direction of the housing 120. The translucent part 121a, the light shielding part 121b, and the flange part 121c are arranged side by side in the X-axis direction, and each extends in the Y-axis direction.

  The light transmitting part 121a transmits light emitted from the light emitting element 112 (light source). The translucent part 121a is made of a translucent material such as a translucent resin material such as acrylic or polycarbonate, or a glass material. The translucent part 121a is formed by, for example, extrusion molding using a resin material such as polycarbonate.

  The translucent part 121a may further have light diffusibility (light scattering). By providing the light transmissive part 121a with light diffusibility, even if the light emitting element 112 is a highly directional LED light source, the light from the light emitting element 112 can be scattered. Crushing feeling (brightness unevenness) due to brightness difference can be suppressed.

  When the light transmissive part 121a has light diffusibility, a light diffusing material such as light reflecting fine particles is dispersed in the light transmissive resin material to produce the light transmissive part 121a or the surface of the light transmissive part 121a made of a transparent member By forming a milky white light diffusing film including a light diffusing material or the like (inner surface or outer surface), the translucent part 121a can have light diffusibility. Alternatively, instead of using a light diffusing material, fine irregularities are formed on the surface of the transparent part 121a made of a transparent member by applying a texture processing or the like, or a dot pattern is formed on the surface of the transparent part 121a made of a transparent member The light transmissive part 121a may be given light diffusibility by printing.

  The upper surface of the light transmitting part 121a is substantially flush with the upper surface of the light shielding part 121b. That is, the upper surface of the light transmitting part 121a and the outer surface of the light shielding part 121b are flush with each other, and the upper surface of the light transmitting part 121a and the upper surface of the light shielding part 121b are continuous surfaces without a step. Thereby, the thin housing | casing 120 can be formed easily.

  In the present embodiment, the translucent portion 121a has a substantially L-shaped cross section. That is, the light of the light emitting element 112 is emitted from both the upper surface portion and the side surface portion of the translucent portion 121 a of the housing 120.

  The light shielding unit 121b shields light from the light emitting element 112. The light shielding part 121b is made of a light shielding material. For example, the light shielding part 121b is made of a white insulating resin material. Therefore, the light shielding part 121b has light reflectivity with respect to visible light. That is, the light shielding unit 121b shields light by reflecting light. In the present embodiment, the light shielding portion 121b is made of white polycarbonate.

  The light shielding portion 121b may be made of a metal material such as aluminum or iron instead of the resin material. Moreover, the material of the light shielding part 121b is not limited to the material that shields light by reflecting light, but may be a material that shields light by absorbing light. In this case, for example, the light shielding part 121b may be made of a black insulating resin material. In addition, the light shielding part 121b is not limited to a non-light-transmissive part that shields incident light by 100%, but may have a low light transmittance and partially transmit light.

  The flange portion 121 c is provided on the upper portion of the housing 120. Specifically, the flange portion 121c is formed in a plate shape so as to protrude outward from the upper portion of the light shielding portion 121b in the width direction of the housing 120. In the present embodiment, the flange 121c is made of the same material as the light shielding part 121b and is formed integrally with the light shielding part 121b. The light shielding part 121b and the flange part 121c are formed by, for example, extrusion molding using a light shielding resin material.

  The cover 121 configured in this manner is integrated by joining the light transmitting part 121a, the light shielding part 121b, and the flange part 121c. For example, the translucent part 121a, the light-shielding part 121b, and the collar part 121c may be integrated by multi-color molding such as two-color molding, or a structure that engages with each of the translucent part 121a and the light-shielding part 121b. May be integrated, or may be integrated by fixing with an adhesive or a screw. In the present embodiment, the cover 121 is formed by two-color extrusion molding.

  The base 122 is a support member that supports the light emitting module 110. The base 122 is made of a light shielding material. For example, the base 122 is made of the same white insulating resin material as that of the light shielding portion 121b, but is not limited thereto.

The metal plate 150 is disposed between the substrate 111 of the light emitting module 110 and the bottom of the base body 122. Further, in order to enhance the insulation, an insulation sheet 160 made of an insulating resin material such as polypropylene is inserted between the substrate 111 and the metal plate 150. Note that the metal plate 150 and the insulating sheet 160 may not be disposed.

  In addition, a groove portion into which an end portion in the width direction (X-axis direction) of the substrate 111 of the light emitting module 110 is inserted is formed on each inner side surface of the base body 122. The movement of the substrate 111 in the width direction is restricted by the pair of grooves. The pair of groove portions extends in the longitudinal direction of the housing 120 and functions as a guide rail when the substrate 111 is slid within the housing 120.

  The cover 121 is formed with a first side wall 121 d that extends in the longitudinal direction of the housing 120. Further, the base 122 is formed with a second side wall portion 122 a extending in the longitudinal direction of the housing 120. The first side wall 121 d of the cover 121 and the second side wall 122 a of the base 122 constitute a partition wall of the lighting unit 100. That is, the inner region of the lighting unit 100 is spatially separated by being divided in the width direction of the lighting unit 100 by the first side wall part 121d and the second side wall part 122a constituting the partition wall.

  Specifically, as illustrated in FIG. 4, the lighting unit 100 includes a first housing region A1 and a second housing region A2 that are divided in the width direction of the lighting unit with such a partition wall therebetween. The first housing region A1 and the second housing region A2 are space regions in the lighting unit 100.
