Description

   The present invention relates to an illumination device using a semiconductor light emitting element such as a light emitting diode as a light source.

  Conventionally, there are those using a fluorescent lamp or an incandescent bulb as a light source. However, a lighting fixture using this type of light source has a diameter of a glass tube or a glass bulb constituting a fluorescent lamp at least. It must be constructed as an instrument having dimensions.

  Moreover, since the power supply part for lighting control of a light emission light source is integrated, the magnitude | size of an instrument will increase further.

  Furthermore, in this type of instrument, in order to control the optical path of the light source, it is necessary to provide an optical path control means for controlling the light in a desired direction by various covers made of a reflector or a translucent material. This leads to an increase in size, resulting in problems of installation space and restrictions on design freedom.

  In other words, a fluorescent lamp or an incandescent lamp or the like as a light source must be configured as a luminaire having an optical path control means such as a so-called reflector, resulting in problems such as an increase in manufacturing cost. Therefore, there is a demand from the market for a lighting device that is smaller and thinner and does not cause installation space problems or design restrictions, and is advantageous in terms of cost.

  In order to solve this problem, lighting fixtures using light-emitting diodes have been developed in recent years as small light-emitting light sources, but fixtures using this light-emitting diode are mainly configured with a separate power supply. The thermal power supply can be avoided by installing the power supply unit separately, but there is a problem that the installation work is complicated.

In order to solve this problem, there is a lighting fixture with a built-in power supply unit (see, for example, Patent Document 1).

  However, light emitting diodes generally have good light rectilinearity. Patent Document 1 discloses a light distribution control member made of a Fresnel lens so as to cover a light emitting diode as a light source, so-called optical path control means. However, the light path control means is configured separately from the light emitting diode and is screwed into a screw portion formed on the base plate.

  In the case of a separate body, the positional relationship between the light emitting diode and the optical path control means tends to fluctuate. For example, in Patent Document 1, the positional relationship between the light emitting diode and the optical path control means changes depending on the degree of screwing. In some cases, the light from the light emitting diode cannot be controlled according to the optical design.

  In addition, in the case of a linear planar light source, the light emitting diodes are arranged in a straight line, so depending on the position of the power circuit board, the light emission that is greatly affected by thermal among the individual light emitting diodes.

FIG. 4 is a right side view, FIG. 4 is an enlarged longitudinal sectional view taken along the line AA in FIG. 1, and FIG. 5 is an explanatory view showing the main part separately.

  The lighting device of the present embodiment is configured as a sink lamp used in a sink in a general household kitchen. Reference numeral 10 denotes a lighting device, a light-emitting element substrate 12 having a semiconductor light-emitting element 11, and a light-transmitting cover. The member 13, the support member 14, the main body case 15, and the power circuit board 16 are configured.

  The semiconductor light emitting element 11 is composed of a light emitting diode (hereinafter referred to as “LED”), and the LED 11 is provided with a plurality of LEDs of the same color, in this embodiment, white, and each LED is unidirectional, that is, an LED. It is composed of the same kind of performance in which light rays are mainly emitted in the axial direction (indicated by a dashed line in FIG. 4).

  Further, a plurality (18 in this embodiment) of LEDs 11 are arranged in a line in a substantially straight line on a long light-emitting element substrate 12 having an elongated planar shape. At this time, the LEDs are arranged such that the directions of the rectangular element pieces are alternately changed at an angle of 90 degrees.

  The light emitting element substrate 12 is made of a heat resistant and electrically insulating synthetic resin.

  As for the long light emitting element substrate 12 in which the 18 LEDs 11 are arranged in a row, two identically arranged light sources having the same shape are prepared, and a total of 36 LEDs are used.

  The translucent cover member 13 is formed of a synthetic resin such as a long, colorless and transparent polycarbonate having a concave cross section and a substantially straight shape, and has a lens body 13a on the concave inner surface, and further a lens body. A recess 13b is formed on the inner surface of the substrate.

  The recess 13b is opposed to each of the 18 LEDs 11 and is formed integrally with the transparent cover member 13 so that 18 holes form a line. The 18 recesses 13b are arranged on the light emitting element substrate 12. Each of the 18 LEDs 11 is arranged one by one.

  The lens body 13a constitutes an optical path control means for controlling the optical path of each LED 11, and is configured to control the optical path of the light beam emitted from the LED so that the light distribution angle is about 30 degrees.

  The light-emitting body A is configured by combining a light-emitting element substrate 12 and a cover member 13 and positioning a light-transmitting cover member 13 having an optical path control means on the LED 11.

  In addition, the positioning of the translucent cover member 13 by the LED 11 is performed by providing the translucent cover member 13 and the light emitting element substrate 12 with an engaging member with another unevenness or the like corresponding to each other, and engaging them. The positioning of both may be performed more reliably.

  Reference numeral 13e denotes attachment flanges integrally formed at both ends of the concave shape, and is a member for attaching the cover member 13 to the support member 14 described later.

  The lengths of the long light emitting element substrate 12 and the cover member 13 are configured to be approximately equal.

  In the figure, reference numeral 14 denotes an elongated, substantially linear support member that supports the light emitting element substrate 12 and the translucent cover member 13, and is made of a metal such as aluminum having good thermal conductivity.

  The support member 14 has a substantially L-shaped cross section, a planar substrate portion 14a, a mounting portion 14c formed of concave grooves 14b and 14b formed in opposite directions on both sides of the substrate portion 14a, and further 90 with respect to the substrate portion 14a. The contact portion 14d for positioning is formed with an angle of degrees.

  The substrate portion 14a, the attachment portion 14c, and the contact portion 14d are integrally formed by drawing an aluminum material.

  The length of the support member 14 is also configured to have substantially the same dimensions as the long light emitting element substrate 12 and the cover member 13.

  The light emitter A described above is incorporated into the support member 14 configured as described above.

  That is, each LED 11 is inserted into the recess 13b of the cover member 13 and the bottom surface of the light emitting element substrate 12 is placed on the substrate portion 14a of the support member in a state where the cover member 13 and the light emitting element substrate 12 are combined. 13 are attached to the recessed grooves 14b and 14b, and the cover member 13, the light emitting element substrate 12, and the support member 14 are positioned and fixed.

  As a result, the optical axis of the LED 11 and the optical axis of the lens body 13a are difficult to shift.

  As described above, two sets of light emitters A having the same configuration and performance and integrated into the support member 14 are prepared.

  The main body case 15 is made of a heat-resistant and electrically insulating synthetic resin, has a rectangular outer shape in plan view, and has a mounting portion 15a having a flat plate surface. Side plates 15b and 15b are integrally formed on both side surfaces of the mounting portion.

  Mounting portions 15c and 15c, which are two mounting pieces standing upright at an angle of 90 degrees and parallel to the side surface plates 15b and 15b on both sides, are integrally formed at a substantially intermediate portion of the plate portion 15a.

  A space portion 15d is formed between the attachment portions 15c and 15c, and support portions 15e and 15e having a planar shape are formed on both sides.

  The side plates 15b and 15b have a substantially chevron-shaped outer shape and are formed with attachment holes 15f made of through holes on both sides.

  Further, the dimension between the side plates 15b, 15b located on both sides of the main body case 15 is configured to be approximately equal to the lengths of the light emitting element substrate 12, the cover member 13 and the support member 14 which are long.

  In the main body case 15 configured as described above, two sets of the light emitters A integrally incorporated in the support member 14 are incorporated.

  That is, both ends of the long support member 14 in which the cover member 13 and the light emitting element substrate 12 are integrated are fitted between the side plates 15 b and 15 b on both sides of the body case 15.

  Further, the planar substrate portion 14a of the support member 14 is placed on the planar support portions 15e and 15e of the main body case 15, and the contact portion 14d formed at an angle of 90 degrees is also set to 90 degrees. Positioning is performed by abutting the mounting portions 15c, 15c formed at the angles of 15mm and 15c so that the angles match.

  At this time, it is assembled so that both end surface portions a of the support member 14 made of aluminum are exposed to the outer surface.

  As described above, the two sets of the light emitters A are positioned with respect to the main body case 15, and the light emitters A and the main body case 15 are reliably assembled in a state where the positional relationship does not change.

  Thus, the state where the optical axis of the LED in the light emitter A is set in a predetermined vertical direction and the light distribution angle is set to about 30 degrees does not change.

  Further, the contact portion 14d of the support member 14 and the attachment portion 15c of the main body case 15 are screwed into the support member 14 and the main body case 15 by screwing bolts 15g from a direction substantially orthogonal to the optical axis of each LED 11 (horizontal direction in FIG. 4). To fix.

  At this time, since the bolting is performed from a direction substantially orthogonal to the optical axis of each LED 11, the support member 14 moves slightly from a predetermined position depending on the tightening condition of the bolt, but the direction is substantially orthogonal to the optical axis. It only moves in the horizontal direction, and the optical axis of each LED 11 does not deviate from the vertical direction.

  For example, when the bolt is tightened from the optical axis direction of the LED (the one-dot chain line direction in FIG. 4), the support member 14 may be inclined with respect to the horizontal plane due to the tightening condition, and this inclination is caused by the optical axis of the LED from the vertical direction. There arises a problem that the predetermined light distribution characteristic cannot be obtained because it is inclined at an angle.

  In the figure, reference numeral 15h denotes a power cord lead-out portion comprising a through hole formed at an angle of 90 degrees from the lower side of one right side plate 15b of the main body case 15 to the bottom surface of the mounting portion 15a.

  The power supply circuit board 16 is mounted with power supply circuit components for controlling the lighting of each LED 11, and is constituted by a long and long printed circuit board having a substantially straight planar shape. The components are mounted so that the longitudinal direction of each component is parallel to the longitudinal direction of the printed circuit board.

  Further, each part is positioned on the bottom surface of the space portion 15d formed in the substantially middle portion of the main body case 15 so as to face the surface side, and both ends of the printed board are fixed by means such as screws.

  As described above, the long light emitting element substrate 12 and the long power supply circuit substrate 16 are adjacent to each other, and the respective plate surfaces are arranged side by side so as to be substantially parallel to the horizontal plane. The illumination device having a substantially linear light emitting surface can be configured, and the plurality of LEDs 11 that are susceptible to thermal influence can be substantially equally affected by the thermal influence from the power supply circuit board 16, thereby providing a plurality of semiconductors. The degree of change in the lifetime and chromaticity of the light emitting element can be made substantially the same.

  Further, the space 15 d that houses the power circuit board 16 of the main body case 15 is covered with a decorative board 17.

  The decorative plate 17 is formed of a long and substantially straight metal plate having a chevron-shaped cross section, its surface is painted in a predetermined color, and the engagement plate is formed toward the inner sides of the chevron. The portions 17a and 17a are attached so as to cover the space portion 15d by fitting the concave portions 14f and 14f formed at the upper end of the contact portion 14d of the support member 14 using the elasticity of the metal plate.

  When disassembling the lighting device configured as described above for repair, inspection or the like, the decorative plate 17 covering the space 15d of the main body case 15 is resisted against the elasticity of the metal plate. Remove from the grooves 14f, 14f.

  In this state, since the power circuit board 16 is exposed, the power circuit board 16 is removed from the space 15d of the main body case 15 to be repaired or exchanged.

  Further, the four bolts 15 g are removed, and the support member 14 is removed from the main body case 15.

  Thereby, the light emitter A in which the cover member 13 and the light emitting element substrate 12 are integrated into the support member 14 can be removed from the main body case 15.

  Furthermore, in a state where the cover member 13 and the light emitting element substrate 12 are combined, the cover member 13 is pulled out from the concave grooves 14b and 14b of the support member 14, and the support member 14 is separated.

  Further, each LED 11 is pulled out from the recess 13 b of the cover member 13 to separate the light emitting element substrate 12 and the cover member 13.

  As a result, each LED 11 is exposed on the light emitting element substrate 12, and in this state, replacement, repair, etc. of the LED are performed.

  In the figure, 18 and 18 are lead wires for wiring connection between the power supply circuit of the power supply circuit board 16 and the LEDs 11 arranged in two rows.

  The power supply circuit is a constant current circuit, and is configured to supply power to each LED 11 connected in series to perform illumination with high power supply efficiency.

  With the above configuration, the plurality of LEDs 11 are arranged in two rows with the decorative plate 17 in between, forming a substantially linear light emitting surface that is rectangular in plan view as a whole, the horizontal dimension a is about 220 mm, and the vertical dimension An illuminating device as a sink lamp having a size of about 85 mm and a height h of about 20 mm, which is smaller and thinner, is configured.

  In order to install the above-configured sink lamp on the top plate of the cupboard located above the sink, four wood screws are attached to the mounting holes 15f formed in the side plates 15b and 15b of the main body case 15. Insert and screw onto the top plate. Further, the power cord is pulled out from the drawer portion 15h of the main body case, connected to a predetermined outlet, supplied with power, and each LED 11 is turned on.

  Each LED 11 has a substantially linear light-emitting surface, and a light distribution angle is set to about 30 degrees, and light rays are radiated in a straight line downward, and desired illumination along the longitudinal direction of a rectangular sink. I do.

  At this time, since both end portions a of the support member 14 made of aluminum are exposed to the outer surface, heat generated from each LED 11 is conducted from the light emitting element substrate 12 to the support member 14 and is radiated to the outside.

  Thereby, the temperature rise of each LED11 is suppressed and the light beam reduction can be prevented.

  As described above, the sink lamp is configured to be small and thin, and can be installed in a narrow space at the top of the sink without problems, and the lighting device projects like a conventional lighting fixture. Therefore, desired illumination can be performed without hindering the work in the sink.

  Furthermore, since the drawer portion 15h is formed with a hole penetrating from both the bottom of the side plate 15b of the main body case 15 to the bottom surface of the mounting portion 15a, the power cord is pulled out in the direction of the side plate 15b of the main body case 15. It can be pulled out in the direction along the plate surface of the top plate from the lower hole and also in the direction penetrating the top plate from the hole in the bottom surface of the mounting portion 15a.

  Although not shown, a pull switch or the like is installed in the main body case 15 so that each LED 11 is turned on and off.

  In the present embodiment, the illuminating device 10 configured as described above can be used alone. For example, two illuminating devices 10 described above are prepared and continuous in the longitudinal direction of the main body case 15. It may be arranged side by side so as to be configured as a longer and narrower illuminating device. Furthermore, it may be arranged side by side so as to be continuous in the short direction perpendicular to the longitudinal direction of the main body case 15 so as to constitute a square lighting fixture having a substantially square shape.

  Furthermore, the light emitter A set at a desired light distribution angle by the elongated light emitting element substrate 12, the cover member 13 and the support member 14 is configured as one standard part, and 1 according to the scale of lighting, the situation, etc. A desired number of light emitters may be prepared, and a desired lighting device may be configured by being provided side by side so as to be continuous in the longitudinal direction or the lateral direction.

  At this time, as the main body case 15, various types of dimensional configurations are prepared in accordance with the standardized number of light emitters A used.

  Each LED 11 is configured in white, but may be configured in red, yellow, green, or a combination of various colors depending on the use of the lighting device.

  The translucent cover member 13 is made of a colorless and transparent synthetic resin. However, the translucent cover member 13 may be colored or semi-transparent, not completely transparent, and the material is not limited to a synthetic resin. You may comprise glass.

  Moreover, although the main body case 15 is made of a heat-resistant and electrically insulating synthetic resin, it is made of a metal having good thermal conductivity such as aluminum so that the heat generated from each LED 11 can be radiated more efficiently. It may be. In this case, electrical insulation from the power circuit board 16 is performed with a separate configuration.

  Although the illuminating device of the present embodiment is configured as a source lamp, it may be configured as various illuminating devices for other homes, facilities, and businesses.

  According to the present embodiment, the long light emitting element substrate and the long power supply circuit substrate are arranged side by side so as to be adjacent to the main body case. Thus, it is possible to provide a lighting device having a substantially linear light-emitting surface that is advantageous in terms of cost.

  In particular, since the power supply circuit board and the light emitting element substrate are disposed so that the plate surfaces thereof are substantially parallel to the horizontal plane, it is possible to achieve further reduction in size and thickness.

  Furthermore, since it is possible to perform desired illumination without providing a large reflector in the lighting fixture, it is possible to provide a lighting device that does not cause an increase in size of the fixture as in a conventional lighting fixture with a reflector.

  Further, since the optical path control means is provided by being positioned corresponding to the semiconductor light emitting element, it is assembled as a light emitter that does not change the positional relationship between them, so that a change in desired light distribution characteristics can be suppressed.

  Since the optical path control means is positioned corresponding to the semiconductor light emitting element and positioned relative to the main body case, it can be reliably incorporated in a state where the positional relationship between the light emitter and the main body case does not change, It is possible to further suppress changes in desired light distribution characteristics.

  Further, since the support member abutment portion and the main body case attachment portion are screwed from the direction substantially orthogonal to the LED optical axis to fix the support member and the main body case, the LED optical axis is deviated from the vertical direction. There is no inclination, and the change in desired light distribution characteristics can be further suppressed.

  In addition, since the light emitting element substrate and the power circuit board are arranged side by side, the plurality of semiconductor light emitting elements that are susceptible to thermal influence can be substantially equally affected by the thermal influence from the power source. The degree of change in the lifetime and chromaticity of the light emitting element can be made substantially the same.

  When disassembling the lighting device configured as described above for repair, inspection, etc., it is possible to repair, replace, etc. the power circuit board with a simple operation of removing the decorative plate covering the space of the main body case. it can.

  In a state where the cover member and the light emitting element substrate are combined, each LED can be pulled out and replaced, repaired, etc. by a simple operation of pulling out from the concave groove of the support member.

  In this embodiment, by preparing and combining a plurality of lighting devices, it is possible to provide a variety of shapes and sizes of lighting fixtures with a simple configuration and method in accordance with the lighting scale and situation. It becomes.

  In the illumination device of this embodiment, a plurality of LEDs are provided adjacent to each other in two rows on the light emitting element substrate 12, and the power supply circuit substrate is vertically installed to achieve further miniaturization and thickness reduction. It is what I did.

  The lighting device of the present embodiment is also configured as a source lamp, and each of the plurality of LEDs 11 is arranged in two lines in a substantially straight line on a long light-emitting element substrate 12 having a long and narrow flat shape. Place them next to each other.

The light emitter A is constituted by

  As in the first embodiment, the light emitter A is configured by combining the light emitting element substrate 12 and the cover member 13 and positioning the light transmissive cover member 13 having the optical path control means on the LED 11.

The concave lens body 13a is fitted and positioned and fixed.

  As a result, as in the first embodiment, the optical axis of the LED 11 and the optical axis of the lens body 13a of the optical path control means are less likely to shift.

  The main body case 15 constitutes a mounting portion 15a composed of a thick mounting base, and side plates 15b and 15b are formed on both side surfaces of the mounting portion.

  A support portion 15e that stands up at an angle of 90 degrees on the outer end surface portion of the mounting portion 15a, is integrally formed with a mounting portion 15c across the side plates 15b and 15b on both sides, and is continuously flat with the mounting portion 15c. Is formed.

  That is, both ends of the long support member 14 in which the cover member 13 and the light emitting element substrate 12 are integrated are fitted between the side plates 15 b and 15 b on both sides of the body case 15.

  Further, the planar substrate portion 14a of the support member 14 is placed on the planar support portion 15e of the main body case 15, and the contact portion 14d formed at an angle of 90 degrees is also set at an angle of 90 degrees. Positioning is performed by abutting on the attachment portion 15c formed in such a manner that the respective corners coincide with each other.

  At this time, the side surface portion a and the upper surface portion b of the support member 14 made of aluminum are assembled so as to be exposed to the outer surface.

  As described above, similarly to the first embodiment, the light emitter A is positioned with respect to the main body case 15, and the light emitter A and the main body case 15 are reliably incorporated in a state where the positional relationship does not change.

  Thus, the state where the optical axis of the LED in the light emitter A is set in a predetermined vertical direction and the light distribution angle is set to about 30 degrees does not change.

  Further, the support member 14 and the main body case 15 are fixed by screwing four bolts 20.

  Further, the main body case 15 is integrally formed with a second mounting portion 15a ′ comprising a mounting base, and stands up at an angle of 90 degrees with respect to the outer end surface portion of the second mounting portion 15a ′. A second mounting portion 15c ′ is formed integrally over the face plates 15b and 15b. As a result, a space portion 15d is formed between the placement portion 15a and the second placement portion 15a ′.

  The decorative plate 17 is supported by the second attachment portion 15c ′.

  That is, the decorative board 17 in the present embodiment is formed of a long heat-resistant and electrically insulating synthetic resin having a substantially L-shaped cross section, and the vertical portion 17a has an angle of 90 degrees with the main body case. Positioning is performed by placing the second mounting portion 15 c ′ formed upright, the horizontal portion 17 b is brought into contact with the side surface portion c of the support member 14, and the three bolts 21 are moved from the vertical portion 17 a to the second portion. It is screwed and fixed to the mounting portion 15a '.

  In this state, the power supply circuit board 16 is vertically brought into contact with the inside of the vertical portion 17a of the decorative board 17, and the bolts 22 are screwed into the vertical portion 17a from the power supply circuit board 16 to fix the power supply circuit board 16.

  As described above, the power supply circuit board 16 is arranged so that the plate surface thereof is substantially orthogonal to the plate surface of the light emitting element substrate 12, and this arrangement contributes to making the entire illumination device more elongated and thinner.

  With the above configuration, each of the plurality of LEDs 11 is formed in two rows adjacent to each other on the light emitting element substrate 12 to form a substantially linear light emitting surface having an elongated rectangular shape in a plan view as a whole, and a lateral dimension a is about 214 mm. Thus, a lighting device is constructed as a source lamp having a smaller size and a thinner thickness, with a vertical dimension b of about 60 mm and a height h of about 18 mm.

  According to the present embodiment, since the plate surface of the power circuit board is arranged so as to be substantially orthogonal to the plate surface of the light emitting element substrate, the illumination device that forms a substantially elongated light-emitting surface of a longer rectangular shape is provided. Can be provided.

  Other configurations, functions, modifications, functions and effects are the same as those in the first embodiment.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and various design changes can be made without departing from the scope of the present invention.
