Description

  The present invention relates to a lighting apparatus suitable for a store such as a show window or a show room that reflects light from a light-emitting body by a reflection layer and indirectly irradiates light to an irradiated site, for display, or for a house such as a reception room or living room. In addition, the present invention relates to a reflecting member used in the lighting fixture.

  For example, as shown in FIG. 3 of Patent Document 1, this type of lighting fixture reflects a light emitted from a substrate 102 on which a plurality of light emitters (LED chips) 104 are attached at intervals, and the light emitters 104. Then, a tool body including a reflecting member that radiates through the opening (light exit surface) 124, and a translucent filler (sealing material) 110 filled in the tool body so as to embed and fix the plurality of light emitters 104. It consists of.

  In the technique of Patent Document 1, the reflecting member is composed of a reflector block 106 which is fixed to be integrally attached facing the substrate 102, and the opening 124 of the instrument body is formed between the substrate 104 and the reflector block 106. The translucent filler 110 is formed in a space surrounded by the substrate 104 and the reflector block 106.

  As shown in FIGS. 4 to 6 of Patent Document 1, the reflecting member of the lighting device of the prior art is attached relative to the substrate 102, so it has to be fixed to the substrate 102 by adhesion or the like. In addition, since the substrate and the reflective member are fixed and attached to each other with a small contact portion, the strength of the instrument body is low, and even if the translucent filler is filled across the substrate and the reflective member, illumination There was a drawback that the device could not be given high durability. Furthermore, if the reflecting member is displaced and fixed with respect to the substrate 1, the position of the reflecting member with respect to the light emitter is also displaced, and the light of the light emitter is not reflected well. It was necessary to provide a reflective layer.

  Means for solving the second problem of the present invention comprises a reflecting member for a lighting fixture having a reflecting layer that reflects light from at least one light emitter, and a support to be supported by the light emitter. It is providing the reflecting member for lighting fixtures characterized by the above-mentioned.

  In the second problem-solving means of the present invention, the support preferably has a light-transmitting property, and the support preferably has a claw for temporarily fixing the light-emitting body.

  According to the present invention, the reflective member is not attached to the substrate, but is attached to the light emitter on the substrate and embedded in the light transmissive filler together with the light emitter. It is possible to provide a lighting device that is fixed and has high durability.

In addition, since the reflecting member is attached to the light emitter rather than relative to the substrate, it is easy to attach the reflecting member, and a part of the light from the light emitter is directly guided to the opening of the instrument body. However, since the other part is reflected by the reflecting layer of the reflecting member and guided to the opening of the instrument body, it is effectively radiated with high intensity in a state where the light is squeezed as a whole without light dispersion. can do.

  A luminaire 10 according to one embodiment of the present invention is illustrated in FIGS. 1-5, which includes a substrate 30 having a plurality of light emitters 20 mounted at intervals and these light emitters. The instrument main body 50 including the reflecting member 40 that reflects light from the light 20 and emits the light through the opening 52H, and the translucent material filled in the instrument main body 50 so as to be embedded and fixed together with the reflecting member 40. It consists of the filler 60 (refer FIG. 2).

  The instrument body 50 includes a housing 52 having a substantially U-shaped cross section having a bottom surface 52B on which the substrate 30 is placed. In the illustrated form, the casing 52 may have both side walls 52S having the same height, but as shown in FIGS. 2 and 9, one side wall 52SR is formed higher than the other side wall 52SL. Has been. The housing 52 is shown to have screw through holes 52TH for screwing the luminaire 10 to a mounting wall W (see FIG. 2) such as a show window at both ends where the substrate 30 does not extend. The attaching means may be an adhesive or other appropriate means other than screws.

  The light emitter 20 can be an LED lamp or other appropriate light emitting element, but in the illustrated example, the substrate 30 is an LED lamp in which a circuit board is also connected to a predetermined drive circuit by printed wiring on the circuit board. It is shown that there is. In FIG. 1, reference numeral 22 denotes a lead wire that is connected to the wiring portion of the circuit board and is connected to an external power source.

  The reflective member 40 is formed on the support 42 so that the light L is reflected toward the opening 52H of the instrument body 50 and the transparent support 42 made of transparent plastic such as polycarbonate which is supported and attached to each light emitter 20. And the reflecting layer 44 formed.

  In the illustrated embodiment, the support 42 of the reflecting member 40 has an L-shaped cross section, and the horizontal wall 42H is a portion that engages with the upper surface of the light emitter 20. The front and rear end surfaces and both end surfaces of the light emitter 20 Claws 42P1 and 42P2 that can be temporarily fixed by being respectively covered. In the illustrated example, the claw 42P1 is formed higher than the claw 42P2.

  The reflection layer 44 of the reflection member 40 is formed on the inner surface (the surface on the side having the horizontal wall) of the vertical wall 42V of the L-shaped support 42. The reflective layer 44 can be formed by adhering a reflective film such as an aluminum foil or depositing aluminum.

  The translucent filler 60 is provided in a portion excluding a portion having the screw through holes 52TH at both ends of the housing 50 in a state where the substrate 30 having the light emitter 20 to which the reflecting member 40 is temporarily fixed is placed on the housing 50. The substrate 30 that is filled and has the light emitter 20 is fixed in the housing 50, and the reflecting member 40 temporarily fixed to the light emitter 20 is fixed on the light emitter 20. As this filler, a silicone polymer or other appropriate material can be used.

  Thus, the reflecting member 40 has the substantially L-shaped support body 42 and the reflecting layer 44 on the inner surface of the vertical wall 42V, and the reflecting member 40 temporarily fixes the support body 42 to each light emitting body 20 to transmit light. When fixed to the light emitter 20 with the conductive filler 60, the reflective layer 44 is positioned perpendicular to one side of the light emitting surface (upper surface) of the light emitter 20, as shown in FIG.

  Therefore, as shown in FIG. 9, the light L from the light emitter 20 is directly radiated to the opening 52H between the lower side wall 52SL of the housing 50 and the vertical wall 42V of the support 42 of the reflecting member 40, and is also reflected. In the portion below the upper edge of the vertical wall 42V of the support 42 of the member 40, the light is reflected by the reflective layer 44 and opened between the lower side wall 52SL of the housing 50 and the vertical wall 42V of the support 42 of the reflective member 40. Radiated to 52H.

  If the reflecting member 40 is not provided, all the light L from the light emitter 20 is widely emitted through the openings 52H between the side walls 52S of the casing 52, as shown in FIG. Although it becomes weak, since the lighting fixture 10 of this invention has the reflection member 40, the light L of the light-emitting body 20 is between the low side wall 52SL of the housing | casing 50, and the vertical wall 42V of the support body 42 of the reflection member 40. Since it is emitted in a narrowed state, light can be emitted with high intensity.

  Another embodiment of the present invention is shown in FIGS. 7 and 8, and in this embodiment, the reflecting member 40 includes a plurality of light emitters 20, and in the illustrated example, each of the three light emitters 20. In this case as well, a translucent filler 60 (not shown) fixes the substrate 30 having the light emitter 20 to the housing 52 and the reflecting member 40 correspondingly. The three light emitters 20 are fixed.

  In this embodiment, not only the reflective layer 44 is positioned corresponding to each light emitter 20, but also the reflective layer 44 extends into the space between the adjacent light emitters 20 (see reference numeral 44E in FIG. 8). ), The light L of the light emitter 20 does not spread between adjacent light emitters 20 as shown in FIG. 10, and it is preferable because the light L can be effectively emitted with high intensity by preventing the light L from diffusing. .

  In the above embodiment, the reflection layer 44 of the reflection member 40 is provided on the vertical wall 42V of the support 42. However, instead of the vertical wall 42V, the wall portion is slightly inclined inward or outward. , May be provided on the inclined wall.

  Moreover, in the said embodiment, although the reflection member 40 is attached for every 1 or several light-emitting body 20, one reflection member 40 may be attached ranging over all the light-emitting bodies 20. As shown in FIG.

Moreover, in the said embodiment, although the support body 42 has translucency, translucency is not necessarily required. For example, the support portion may be a ring shape, and the ring-shaped support portion may be fitted to the side surface of the light emitter.
Furthermore, in the said embodiment, although the reflection member is being fixed to the light-emitting body with the translucent filler, it is not necessary to use a translucent filler. For example, it is possible to provide a support member for the reflecting member with a retaining elastic part and fix it to the light emitter, and it is also possible to fix the support member directly to the light emitter with an adhesive.

  According to the present invention, since the reflecting member is directly attached to the light emitter on the substrate and embedded in the light-transmitting filler together with the light emitter, the reflective member has high durability and is not accompanied by light dispersion. Therefore, it can radiate with high intensity in a state where light is focused, and has high industrial applicability.
