Description

  The present invention relates to a luminaire and a method for manufacturing the luminaire, and more particularly to a luminaire having a specific wavelength cut and a method for manufacturing the luminaire.

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

  For example, a manufacturing process of a liquid crystal display or a semiconductor device includes a photolithography process using a photosensitive material such as a photoresist that reacts with light of a specific wavelength. At this time, the illumination in the clean room needs to be insensitive to the photosensitive material used in the photolithography process. While the wavelength of an exposure light source has been shortened by miniaturization of a semiconductor circuit, the g-line (wavelength 436 nm) of a high-pressure mercury lamp is inexpensive, and thus is frequently used in applications that do not require such miniaturization.

  Conventionally, as a light source for indoor use used in such a clean room, a light source (so-called “yellow lamp”) in which a short wavelength region of 500 nm or less is completely cut has been used. The problem is that the number of lamps increases and power consumption increases, and the color gap between the outside and the room increases, so that the person feels sick when leaving the room. Here, the clean room in which the yellow lamp is arranged is generally called a yellow room.

  For this reason, in Patent Document 1, an illumination light source that has substantial emission intensity from 450 nm to 500 nm and does not have substantial emission intensity in a region shorter than 400 nm and a product in a photosensitive state are placed. There has been proposed a “manufacturing system that uses a photoresist having a product mounting portion whose appearance is yellowish”. The technical point of Patent Document 1 is that a product mounting portion having an appearance of yellow is provided (Claim 1 of the Patent Document). By the way, Patent Document 1 discloses an “illumination light source that has substantial emission intensity from 450 nm to 500 nm and does not have substantial emission intensity in a region where the wavelength is shorter than 400 nm” (Claim 1). However, no specific example of such an illumination light source is shown.

  Conventionally, when dimming LED lighting, a dimming agent such as an ultraviolet absorber has been disposed in the housing portion of the LED element. Specifically, Patent Document 2 discloses a straight tube illuminating device instead of a fluorescent lamp having a structure in which an ultraviolet absorber is contained in a resin covering an LED element. Patent Document 3 discloses a structure in which a light emission 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. A straight tube luminaire is disclosed. Patent Document 4 discloses a cylindrical LED illumination cover diffuser that includes a light diffusing agent and a pigment that cuts at least part of a wavelength range of 300 to 500 nm.

  On the other hand, it is necessary to cut a specific wavelength in the ultraviolet region similarly to the above in the portable lighting fixture used for equipment inspection in the above-mentioned yellow room. The instrument was not present. Therefore, conventionally, an ultraviolet absorbing film is wrapped around a flashlight. In addition, although the use is different, in order to prevent insects from reacting particularly to ultraviolet rays and gathering in light, Patent Document 5 discloses that the inner surface of a synthetic resin arc-shaped transparent cover that covers the light source is 300 to 400 nm. Patent Document 6 in which a transparent filter that absorbs ultraviolet rays is pasted, and a resin material of a cylindrical transparent glove that covers a light source are kneaded with an ultraviolet absorber that cuts 400 nm or less are provided.

  However, since the ultraviolet absorber is expensive, if it is contained in a portion constituting the main body of the lighting fixture and molded with resin, the amount of the ultraviolet absorber used increases and the cost increases. On the other hand, forming into a film form that requires a small amount of ultraviolet absorber is difficult to produce in a small quantity, and there is still a problem of increasing the cost when producing a small lot. In addition, it is necessary to adjust the specific wavelength to be cut according to the application and mode of using the lighting fixture, but in this case, if the dimming agent was changed for each adjustment, the productivity was It ’s bad and it ’s expensive.

  Therefore, in view of the above-described situation, the present invention intends to solve the problem that the amount of expensive light control agents such as ultraviolet absorbers is kept to a minimum and suitable for small-lot production, and the cost is reduced as a whole. It is in the point which provides the manufacturing method of the lighting fixture and the lighting fixture which cut the specific wavelength which can aim at.

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

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

  The housing 1 may be a straight tube type, a surface type, a bulb fluorescent lamp type, an annular type, or a bulb type depending on the use environment, but for reasons such as uniformity of light, versatility for general facilities and factories, The straight pipe type is 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 that closes 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 long side in a fitted state.

  The light source 5 may be either an organic EL or an LED element, but an LED element that is extremely excellent in brightness, light emission efficiency, and energy saving efficiency is most suitable in consideration of application to a lighting fixture. For example, red, yellow, and blue can be used for the LED element 5, 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 made compact.

  Here, the bullet-type LED element 5 is an LED chip mounted in a cup formed integrally with a lead frame, encapsulating a resin in which a phosphor is dispersed in a cup, and surrounding the resin into a bullet-shaped epoxy. It is a structure molded with resin. The bullet-type LED is characterized by high brightness (high luminous intensity) by narrowing the beam angle due to the lens effect (such as a beam angle of 10 to 60 degrees).

  The surface-mounted LED element 5 is an LED chip mounted in a package molded of ceramic or resin, encapsulated with a resin such as epoxy or silicone in which a phosphor is dispersed, It is a structure that extracts light using the structure. Further, it is possible to increase the brightness by mounting one to four or more LED chips in one package by structurally designing the pattern of the package substrate.

As shown in FIGS. 4 to 7, the dimming member is integrally provided with a plurality of cap portions 6 that respectively surround the plurality of LED elements 5, and is used for locking in the locking holes 11. A pair of claw pieces 12 are provided.

  More specifically, the light source array 2 has a plurality of LED elements 5 arranged in a straight line 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 includes a plurality of the cap portions 6 connected at regular intervals, and claw pieces 12 that are locked to the locking holes 11 on both sides of each cap portion 6. . By fitting the light control 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. 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 mounted on the surface of 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, a pin 10 of one base 8 is connected to the wiring pattern of the substrate 4 at one end by a harness, a bridge diode is mounted, and current is supplied to each LED element 5 on the substrate 4. And the said light control member 3 connects the said cap parts 6 2-22 pieces, However, It is desirable that 8-11 pieces are connected for reasons, such as reduction of a manufacturing man-hour and the ease of a fitting operation | work. . In the present embodiment, the light control member 3 has a structure in which eight cap portions 6 are linearly connected at regular intervals by a constricted connection portion 13. In addition, the arrangement | sequence of the said some cap part 6 becomes a linear form or a curve form according to the arrangement | sequence of the said LED element 5.

  Here, the shape of the cap portion 6 of the light adjusting member 3 may be any solid shape such as a hemisphere, a cube, a triangular pyramid, a triangular prism, and a cylinder. However, there is no corner portion and light is transmitted uniformly. A hemisphere is most suitable. In the case of a hemispherical shape, the cap portion 6 of the light control member 3 has 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 adjusted accordingly.

  The base material resin of the light control member 3 is, for example, a thermoplastic resin such as vinyl chloride, vinyl chloride resin, polycarbonate resin, polyethylene terephthalate, or polymethyl methacrylate resin (PMMA). Polycarbonate resin is most suitable because of its excellent rate.

  As the light adjusting agent to be blended with the base resin, an ultraviolet absorber, a visible light absorber, a pigment, and a dye are used. All indoor lighting fixtures used in the yellow room of a semiconductor factory are preferably used. In particular, it is preferable to use an ultraviolet absorber that cuts off the g-line (436 nm) of a high-pressure mercury lamp and does not excessively absorb a blue component with high emission intensity.

  The light-modulating member 3 uses a resin material in which a base material resin is blended with a light-modulating agent and is further blended with commonly used lubricants, heat stabilizers, and the like, and is used for injection molding, press molding (vacuum molding, pressure molding, heat In a light control member having a three-dimensional structure such as a cap portion, injection molding is desirable for reasons such as reducing material costs and dealing with small lots. In addition, once the mold is manufactured, the light control member can be easily manufactured repeatedly even when it is necessary to change the light control agent. Therefore, compared with the film format which manufactures a roll, it is easy to change and adjust a light control agent, and can suppress the raise of the cost of a lighting fixture 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 off ultraviolet rays having a specific wavelength is poor. On the other hand, if it exceeds 3.0% by weight, the effect of ultraviolet ray cutting is not proportionally improved, and it is uneconomical. In addition, if the amount is less than 0.5% by weight, a remarkable ultraviolet cut effect cannot be obtained. On the other hand, if the amount exceeds 1.5% by weight, the bleed out becomes remarkable and the ultraviolet cut effect is lowered.

  The resin used for the housing 1 is preferably vinyl chloride resin, polycarbonate, polyethylene terephthalate, polyethylene, polypropylene, acrylic resin, or the like. More preferably, at least one selected from the group consisting of vinyl chloride resin, polycarbonate, polyethylene terephthalate, and polymethyl methacrylate resin (PMMA) in consideration of the balance between transparency, light-resistant deterioration, and cost. Resin.

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

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

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

The power switch 16 is provided in the base end side cover portion 20, and a battery (not shown) is accommodated in a space formed by the base portion 18 and the base end side cover portion 20, so that the power source A current is supplied to the LED element of the light source 5 through the switch 16. Further, the magnet 17 is bonded and integrated in a recess 23 formed on the back side of the base portion 18.

  In the present embodiment, the base portion 18 has a structure in which a molded product divided at the central portion is joined and integrated, but the entire base portion 18 may be integrally formed. The division is more economical because a small mold and 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 by the holding groove 9 in the cylindrical tube 19.
