Description

The present invention relates to a luminaire, and more particularly to a luminaire with a specific wavelength cut.

Conventionally, lighting fixtures that cut a specific wavelength have been used in the manufacturing process of liquid crystal displays and semiconductor devices, or as lighting for directing. In recent years, as an alternative to general lighting, white LED lighting with low power consumption and high luminous efficiency has become widespread. Since the light emitted from the white LED element includes a wide wavelength range, it is used by dimming the light in a target wavelength range with a filter that cuts a specific wavelength. The filter used here contains a substance having an action of absorbing light having a specific wavelength.

For example, in the manufacturing process of a liquid crystal display or a semiconductor device, there is a photolithography process using a photosensitive material such as a photoresist that reacts with light of a specific wavelength. At this time, the lighting in the clean room needs to be insensitive to the photosensitive material used in the photolithography process. While the wavelength of light sources for exposure is becoming shorter due to the miniaturization of semiconductor circuits, the g-line (wavelength 436 nm) of high-pressure mercury lamps is inexpensive and is therefore widely used in applications that do not require such miniaturization.

Conventionally, as an indoor light source used in such a clean room, a light source that cuts off all short wavelength regions of 500 nm or less (so-called "yellow lamp") has been used, but it is dark due to poor luminous efficiency. There was a problem that the number of lights increased and power consumption increased, and there was a problem that the color gap with the outside was large, which made me feel sick when leaving the room. Here, a clean room in which a yellow lamp is arranged is generally referred to as a yellow room.

Therefore, in Patent Document 1, "an illumination light source having a substantial emission intensity from 450 nm to 500 nm and having no substantial emission intensity in a region shorter than 400 nm and a product in a photosensitive state are mounted. A "manufacturing system using a photoresist having a product mounting portion having a yellowish appearance" has been proposed. The technical gist of Patent Document 1 is that a product mounting portion having a yellowish appearance is provided (claim 1 of the same patent document). By the way, Patent Document 1 discloses "an illumination light source having a substantial emission intensity in the range of 450 nm to 500 nm and no substantial emission intensity in a region having a wavelength shorter than 400 nm" (claim 1), and more white light. However, no specific example of such an illuminating light source is given.

Conventionally, when dimming LED lighting, a dimming agent such as an ultraviolet absorber is arranged in the housing portion of the LED element. Specifically, Patent Document 2 discloses a straight tube type lighting fixture as a substitute for a fluorescent lamp having a structure in which a resin covering an LED element contains an ultraviolet absorber. Further, Patent Document 3 has a structure in which the light emitting surface of an LED array source in which a plurality of LED elements are arranged on a support frame is covered with an arc-shaped light filter containing a light absorber that absorbs light of a specific wavelength. Straight tube lighting fixtures are disclosed. Further, Patent Document 4 discloses a cylindrical diffuser for an LED lighting cover containing a light diffuser and a dye that cuts at least a part of a wavelength range of 300 to 500 nm.

On the other hand, even in the portable lighting equipment used for equipment inspection in the above-mentioned yellow room, it is necessary to cut a specific wavelength in the ultraviolet region as described above, but the dedicated portable lighting that can be used for such a purpose. The instrument did not exist. Therefore, in the past, a flashlight was used by wrapping an ultraviolet absorbing film around it. Although the usage is different, in order to prevent insects from reacting particularly to ultraviolet rays and gathering in the light, in Patent Document 5, the inner surface of the arc-shaped transparent cover made of synthetic resin covering the light source has a range of 300 to 400 nm. Patent Document 6 provides a resin material of a cylindrical transparent glove that covers a light source and a kneaded ultraviolet absorber that cuts 400 nm or less, to which a transparent filter that absorbs ultraviolet rays is attached.

Japanese Patent No. 5221267 Utility Model Registration No. 3134432 Japanese Unexamined Patent Publication No. 2012-104480 Japanese Unexamined Patent Publication No. 2016-103017 Jitsukaihei 3-58801 (Microfilm of Jitsugyohei 1-119610) Japanese Unexamined Patent Publication No. 10-334701

However, since the ultraviolet absorber is expensive, if it is contained in a portion constituting the main body of the luminaire and molded by resin, the amount of the ultraviolet absorber used increases and the cost increases. On the other hand, it is difficult to form a film into a film that requires only a small amount of an ultraviolet absorber, and there is a problem that the cost is high when small lot production is performed. In addition, it is necessary to adjust the specific wavelength to be cut according to the application and mode in which the lighting equipment is used. In this case, if the dimmer is changed for each adjustment, the productivity will be improved. It's bad, and the cost is high.

Therefore, in view of the above situation, the present invention seeks to solve the problem by minimizing the amount of expensive dimmers such as ultraviolet absorbers to be used, and also suitable for small lot production, resulting in cost reduction as a whole. The point is to provide a lighting fixture that cuts a specific wavelength that can be achieved.

Next, the present invention will be described in more detail based on the embodiments shown in the accompanying drawings. 1 to 3 show the lighting fixture of the first embodiment according to the present invention, FIGS. 4 to 7 show the details of the main part thereof, and FIG. 8 shows the emission spectrum and the ultraviolet ray of the white LED element used in the embodiment. 9 to 13 show the absorption characteristics of the absorber, FIGS. 9 to 13 show the lighting fixture of the second embodiment according to the present invention, in which reference numeral 1 is a housing, 2 is a light source array, 3 is a dimming member, and 4 is a substrate. Reference numeral 5 indicates a light source (LED element) 5.

As shown in FIGS. 1 and 2, the luminaire according to the present invention can surround the housing 1, the light source array 2 in which a plurality of light sources 5 are surface-mounted on the substrate 4, and the light emitting portion of the light source 5. The housing 1 includes a dimming member 3 having a cap portion 6 and a dimming agent that cuts a specific wavelength in a base resin, and a light source array 2 in a state where the dimming member 3 is attached to the substrate 4. It is a structure held inside.

The dimming agent to be blended in the dimming member can be appropriately adopted as long as it has a property of cutting a specific wavelength, but in the present embodiment, an ultraviolet absorber having a property of effectively absorbing ultraviolet rays is used. ..

The housing 1 may be a straight tube type, a surface type, a bulb fluorescent lamp type, a ring type, or a bulb type depending on the usage environment, but for reasons such as light uniformity and versatility for general facilities / factories, the housing 1 may be of a straight tube type, a surface type, a bulb fluorescent lamp type, a ring type, or a bulb type. The straight tube type is the most suitable. Specifically, as shown in FIGS. 2 and 3, the housing 1 is composed of a transparent long cylindrical tube 7 and a base 8 for closing both ends thereof. The cylindrical tube 7 is provided with a pair of holding grooves 9 on the inner surface for holding both sides of the substrate 4 on the longitudinal side in a fitted state. Further, the base 8 is provided with two pins 10 each of which can be mounted in the same socket as a conventional fluorescent lamp and for supplying electric power to the light source 5, and is fixed to the cylindrical tube 7 with a silicone encapsulant. ing.

The light source 5 may be either an organic EL or an LED element, but an LED element having extremely excellent brightness, luminous efficiency, and energy saving efficiency is most suitable in consideration of application to lighting equipment. For the LED element 5, for example, red, yellow, blue, or the like can be used, but white is most preferable. Further, in the case of the LED element 5, either a bullet type or a surface mount type may be used, but the surface mount type is preferable because it can be configured compactly.

Here, the bullet-shaped LED element 5 is a shell-shaped LED element 5 in which an LED chip is mounted in a cup integrally formed with a lead frame, a resin in which a fluorescent substance is dispersed is sealed in the cup, and the periphery thereof is made into a bullet-shaped epoxy. It is a structure molded with resin. The feature of the bullet-shaped LED is that it is possible to increase the brightness (high luminous intensity) by narrowing the beam angle due to the lens effect (beam angle 10 to 60 degrees, etc.).

Further, the surface mount type LED element 5 is a reflector in which an LED chip is mounted in a package molded of ceramic or resin, and a resin such as epoxy or silicone in which a phosphor is dispersed is enclosed in the package. It is a structure that takes out light by using the structure. Further, structurally, by designing the pattern of the package substrate, it is possible to mount 1 to 4 or more LED chips in one package to increase the brightness.

As shown in FIGS. 2, 3 and 7, the light source array 2 is the substrate 4 and is provided with a pair of locking holes 11 around the LED element 5. Then, as shown in FIGS. 4 to 7, the dimming member is integrally provided with a plurality of cap portions 6 that surround the plurality of LED elements 5, respectively, for locking into the locking holes 11. A pair of claw pieces 12 are provided.

More specifically, in the light source array 2, a plurality of LED elements 5 are linearly arranged at regular intervals on a substrate 4 and surface-mounted, and the locking holes 11 are provided on both sides of each LED element 5. The dimming member 3 has a plurality of cap portions 6 connected at regular intervals, and claw pieces 12 for locking to the locking holes 11 are provided on both sides of each cap portion 6. .. By fitting the dimming member 3 from the surface side of the substrate 4, each LED element 5 is surrounded by each cap portion 6, and at the same time, the claw piece 12 is elastically inserted into the locking hole 11. It locks. The shape of the substrate 4 and the arrangement of the LED elements 5 are determined according to the shape of the lighting fixture, and for example, the LED elements 5 may be arranged in a curved shape.

In the present embodiment, the light source array 2 has 22 LED elements 5 surface-mounted on each of the four substrates 4, and the substrates 4 are connected to each other by jumper pins (not shown) and integrated in a circuit. Further, the pin 10 of one of the bases 8 is connected to the wiring pattern of the board 4 at one end by a harness, and a bridge diode is mounted to supply a current to each LED element 5 on the board 4. In the dimming member 3, 2 to 22 cap portions 6 are connected in series, but it is desirable that 8 to 11 cap portions are connected for reasons such as reduction of manufacturing man-hours and ease of fitting work. .. In the present embodiment, the dimming member 3 has a structure in which eight cap portions 6 are linearly connected at regular intervals by a constricted connecting portion 13. The arrangement of the plurality of cap portions 6 may be linear or curved depending on the arrangement of the LED elements 5.

Here, the shape of the cap portion 6 of the dimming member 3 may be any three-dimensional shape such as a hemisphere, a cube, a triangular pyramid, a triangular prism, a cylinder, etc. A hemisphere is the most suitable. Further, in the case of a hemispherical shape, the size of the cap portion 6 of the dimming member 3 is preferably a radius of 3 to 8 mm, preferably 4 to 5 mm from the viewpoint of ease of handling. The height is 3 to 8 mm, preferably 4 to 5 mm. The distance between the LED elements 5 is 8 to 25 mm, preferably 10 to 15 mm, and the distance between the cap portions 6 is also adjusted accordingly.

As the base resin of the dimming member 3, for example, a thermoplastic resin such as vinyl chloride, vinyl chloride resin, polycarbonate resin, polyethylene terephthalate, polymethyl methacrylate resin (PMMA) is used, but the strength and transmission are high. Polycarbonate resin is the most suitable because of its excellent rate.

As the dimming agent to be blended in the above-mentioned base resin, an ultraviolet absorber, a visible light absorber, a pigment, and a dye are used. It is suitably used for all indoor lighting fixtures used in the yellow room of a semiconductor factory. In particular, it is preferable to use an ultraviolet absorber that does not excessively absorb the blue component having high emission intensity while cutting the g-ray (436 nm) of the high-pressure mercury lamp.

The dimming member 3 uses a resin material in which a dimming agent is blended with these base resin and further usually used, such as a lubricant and a heat stabilizer, and is used for injection molding and press molding (vacuum molding, pressure molding, heat). It is molded into a predetermined shape by (drill molding) and extrusion molding, but for dimming members having a three-dimensional structure such as a cap part, injection molding is desirable for reasons such as material cost reduction and small lot support. Further, once the mold is manufactured, the dimming member can be easily repeatedly manufactured even when it becomes necessary to change the dimming agent. Therefore, it is easier to change and adjust the dimmer as compared with the film format in which the roll is manufactured, and the cost increase of the lighting equipment can be suppressed as a whole.

The ratio of the ultraviolet absorber to the base resin is 0.1 to 3.0% by weight, preferably 0.5 to 1.5% by weight. If it is less than 0.1% by weight, the effect of cutting ultraviolet rays of a specific wavelength is poor, while if it exceeds 3.0% by weight, the effect of cutting ultraviolet rays is not proportionally improved and it is uneconomical. Of the preferable ratio, if it is less than 0.5% by weight, a remarkable effect of blocking ultraviolet rays cannot be obtained, while if it exceeds 1.5% by weight, bleed-out becomes remarkable and the effect of blocking ultraviolet rays is lowered.

Examples of the resin used for the housing 1 include vinyl chloride resin, polycarbonate, polyethylene terephthalate, polyethylene, polypropylene, and acrylic resin. More preferably, at least one selected from the group of vinyl chloride resin, polycarbonate, polyethylene terephthalate, and polymethyl methacrylate resin (PMMA) in consideration of the balance between transparency, deterioration resistance due to light, and cost. Resin.

FIG. 8 shows the emission spectrum of the white LED element 5 used in the present embodiment and the absorption characteristics of the ultraviolet absorber. As the ultraviolet absorber, one having a characteristic of selectively absorbing ultraviolet rays having a wavelength near the absorption peak wavelength (Λmax) of 394 nm was used.

A polycarbonate resin (manufactured by Idemitsu Kosan Co., Ltd.) was impregnated with 0.5% by weight of an ultraviolet absorber and molded by injection molding to prepare a dimming member 3 having a cap portion 6 having a thickness of 1.0 mm. Next, the light source array 2 was manufactured by covering the light emitting portion of the white LED element 5 mounted on the substrate 4 with the cap portion 6 of the dimming member. The g-line (436 nm) transmittance of the cap portion 6 of the dimming member 3 was 0.08%. The spectral spectrum of the light source array 2 was measured.

In the light obtained by the produced light source array 2, wavelengths having a wavelength of 440 nm or less, specifically, a wavelength of about 436 nm or less were substantially cut. For this reason, the luminaire of the present invention cuts light of a specific wavelength that reacts with the photosensitive material in the process of using a photosensitive material such as a photoresist, and the obtained light is yellowish. It can be seen that a white color that is very close to natural light can be obtained.

Next, the lighting fixture of the second embodiment according to the present invention will be described with reference to FIGS. 9 to 13. The lighting fixture of the present embodiment is a portable lighting fixture that can be carried around and used, and the housing 1A includes a light projecting unit 14 having a light source array 2 in a state where the dimming member 3 is attached to the substrate 4, and one end thereof. It is composed of a grip portion 15 provided in the portion.

Here, the overall shape of the housing 1A is a stick shape, and the power switch 16 of the light source 5 is provided in an appropriate place, preferably the grip portion 15, of the housing 1. Further, a magnet 17 is formed in a part of the housing 1 so that it can be attracted to and held by a facility made of a magnetic material, a steel portion of a pillar, or the like.

More specifically, as shown in FIGS. 9 to 12, the housing 1A has a semi-cylindrical base portion 18, a cylindrical tube 19 housed in a groove on the distal end side of the base portion 18, and the base portion 18. The base end side cover portion 20 is attached to the proximal end side, and the distal end side cover portion 21 is attached to the distal end side of the base portion 18, and the proximal end side cover portion 20 and the distal end side cover portion 21 are attached to the base portion 18. Both ends of the cylindrical tube 19 are held by fixing the cylindrical tube 19 to the screw 22. Therefore, about half of the cylindrical tube 19 is exposed.

Here, the exposed portion of the cylindrical tube 19 becomes the light projecting portion 14, and the portion to which the base end side cover portion 20 is attached becomes the grip portion 15. The power switch 16 is provided in the base end side cover portion 20, and a battery (not shown) is housed in a space portion formed by the base portion 18 and the base end side cover portion 20, and the power supply is supplied. A current is supplied to the LED element of the light source 5 via the switch 16. Further, the magnet 17 is adhered and integrated in the recess 23 formed on the back surface side of the base portion 18.

In the present embodiment, the base portion 18 has a structure in which molded products divided at the central portion are joined and integrated, but the entire base portion 18 may be integrally molded. It is more economical to divide because a small mold and a molding machine can be used. The cylindrical tube 19 is the same component as the cylindrical tube 7 of the first embodiment, and the same light source array 2 is held in the cylindrical tube 19 by a holding groove 9. The light source array 2 of this embodiment is shown in FIG. Since the dimming member 3, the substrate 4, and the light source 5 constituting the light source array 2 are the same as described above, the same components are designated by the same reference numerals and the description thereof will be omitted.

The total length of the portable lighting fixture of the present embodiment is preferably 300 to 500 mm in that the brightness as lighting is 500 lumens (lm) or more and the ease of handling is ensured at the time of equipment inspection. The overall shape of the portable luminaire may be any shape such as a stick shape, a lantern shape, a pen shape, a bar shape, etc., and a stick shape is desirable in that it can uniformly illuminate the entire object in equipment inspection.

By arranging the magnet 17 on the back surface of the base portion 18 as described above, it is possible to attract and fix the magnet 17 to equipment made of a magnetic material such as steel or a pillar, and the work can be done by taking the hand away from the lighting equipment. The light projecting unit 14 of the portable lighting fixture may be a straight tube type, a surface type, a bulb fluorescent type, a bulb type, or the like, and the straight tube type is desirable in that it can uniformly illuminate the entire object in equipment inspection.

As the power switch 16, various switches such as a button switch, a slide switch, and a rocker switch can be adopted, but the button switch is desirable because it can be formed in a small space and the overall shape can be made compact.

The grip portion 15 occupies about 1/3 of the entire lighting fixture, and may have any shape such as a cylinder, a grip shape, and a ring shape. A cylindrical shape or a grip shape is preferable because it does not cast a shadow on the light. The materials of the base portion 18, the base end side cover portion 20 and the tip end side cover portion 21 are ABS resin, nylon resin, vinyl chloride resin, polycarbonate, polyethylene terephthalate, polyethylene, polypropylene, acrylic resin, and rubber resin. , Elastomer resin and the like, but ABS resin is preferable because it is relatively inexpensive and can impart sufficient strength as a portable lighting device.

The power supply may be either an external power supply or an internal power supply. In the case of an internal power supply (battery), there is no need to use a power cord, and there is no risk of the power cord being caught in mechanical equipment when carrying. In the case of an external power supply, the overall weight is light, and it does not burden the operator even during long-term inspection work.
