  Further, in the lighting device 1 according to the embodiment described below, the portion 102 of the radiating fin below the base 110 extends outward from the inner diameter of the base 110.

(External appearance of lighting device)
FIG.1 and FIG.2 is a perspective view which shows the example of an external appearance of the illuminating device 1 which concerns on embodiment. In FIG. 1, the example which looked at the illuminating device 1 from diagonally upward direction is shown, and in FIG. 2, the example which looked at the illuminating device 1 from diagonally downward direction is shown.

  The illuminating device 1 shown in FIGS. 1 and 2 is, for example, a downlight type luminaire that is embedded in an indoor ceiling. The illuminating device 1 shown in FIGS. 1 and 2 illuminates the room located in the downward direction shown in FIGS. 1 and 2, for example, by causing a light emitting element such as an LED to emit light. Such an illuminating device 1 includes a radiator 100, a planar substrate 110, a mounting member 200, a decorative frame 400, chassis 510 and 520, and a reflector 700.

  The radiator 100 is made of a metal having high thermal conductivity. For example, the radiator 100 is molded by aluminum die casting. The radiator 100 includes a plurality of radiating fins that are planar members. A light emitting module 600 having a light emitting element such as an LED is provided inside the radiator 100 (see FIG. 5). The heat radiator 100 releases heat generated from the light emitting element to the outside. Thereby, the heat radiator 100 can suppress the temperature rise of the lighting device 1. As will be described later, the radiator 100 is attached to the base 110 with a fixing screw or the like.

  The substrate 110 is a member that supports the radiator 100. The base material 110 is an annular member, for example, and is provided around the radiator 100. Here, an example of the position where the base material 110 is provided will be described. Here, a force is applied in a direction in which the two extending portions 704a of the fixed spring 704 approach each other, and the length of the fixed spring 704 in a state where the distance between the two extended portions 704a becomes substantially zero is “L1”. And Similarly, the length of the fixed spring 705 in a state where the force is applied and the distance between the two extending portions 705a becomes substantially zero is “L2”. The base material 110 is provided at a position where the distance between the base material 110 and notches 104 and 105 to be described later is larger than “L1” and “L2”. That is, in the radiator 100, the position where the base 110 is attached is configured such that the base 110 does not contact the fixed spring 704 and the fixed spring 705. Therefore, it can prevent that the base material 110 and the extending | stretching part 704a, 705a contact.

  Further, around the radiator 100, a notch 104 into which the extending portion 704a of the fixed spring 704 is inserted is formed, and a member 106 in which a notch 105 into which the extended portion 705a of the fixed spring 705 is inserted is formed. Is provided. Specifically, the member 106 and the radiator 100 are integrally formed. Therefore, the number of parts of the member 106 and the heat dissipation unit 100 is one. Therefore, it can suppress that the number of parts increases. The notch 104 can be formed on the member 106 at a central portion between two adjacent chassis 510 and 520. Thereby, when the extending portion 704a of the fixed spring 704 is inserted through the notch 104, the extending portion 704a and the chassis 510 and 520 can be prevented from contacting each other. In addition, the notch 104 can be formed in the member 106 with an interval of a predetermined value or more from each of the two adjacent chassis 510 and 520. Also by this, when the extending portion 704a of the fixed spring 704 is inserted through the notch 104, it is possible to prevent the extending portion 704a and the chassis 510, 520 from contacting each other. The notch 105 is formed at a position facing the notch 104. Similarly to the notch 104, the notch 105 can be formed on the member 106 at the central portion between the two adjacent chassis 510 and 520. Similarly, the notch 105 can be formed in the member 106 with an interval of a predetermined value or more from each of the two adjacent chassis 510 and 520.

  Further, the notches 104 and 105 are larger in the inner portion than in the outer portion (see FIG. 5). Therefore, according to the member 106 having the notches 104 and 105, the extending portions 704a and 705a of the fixed springs 704 and 705 can be supported more reliably.

  Further, the portion 102 of the heat radiating fin below the base 110 extends beyond the inner diameter of the base 110. Thereby, in the part 102 of the radiation fin below the base material 110, the magnitude | size of a radiation fin becomes larger. Therefore, according to the heat radiator 100, more heat generated from the light emitting element can be released to the outside.

  The attachment member 200 is a member that can be attached to the ceiling. For example, the lighting device 1 is installed on the ceiling by attaching the mounting member 200 to the ceiling. The attachment member 200 is attached to the base material 110 with a fixing screw or the like. The mounting member 200 is appropriately provided with holes so as not to obstruct the flow of air discharged from the radiator 100.

  The decorative frame 400 is made of, for example, a synthetic resin such as ABS resin or a metal such as aluminum die casting. The decorative frame 400 is formed in a cylindrical shape with both upper and lower ends opened in a substantially circular shape, and has an annular flange 410 that protrudes outward from the lower end.

  The chassis 510 and 520 are rod-shaped fixing members that are molded from a metal such as aluminum die casting, for example. Such chassis 510 and 520 are fixed to a part of the peripheral part of the base 110 and a part of the peripheral part of the decorative frame 400. For example, one end of the chassis 510 is attached to a part of the peripheral part of the base 110 by a fixing screw or the like, and the other end of the chassis 510 is attached to a part of the peripheral part of the decorative frame 400 by a fixing screw or the like. . Similarly, one end of the chassis 520 is attached to a part of the peripheral part of the base 110 by a fixing screw or the like, and the other end of the chassis 520 is attached to a part of the peripheral part of the decorative frame 400 by a fixing screw or the like. It is done. Thereby, the chassis 510 and 520 fix the base material 110 and the decorative frame 400 in a separated state.

  The chassis 510 and 520 are fixed to the base 110 and the decorative frame 400 so that a gap is formed between the chassis 510 and 520. Accordingly, heat generated from the light emitting element is released from the radiator 100 into the atmosphere. Therefore, according to the chassis 510 and 520, the heat dissipation effect can be improved.

  The chassis 510 and 520 are fixed to the base 110 and the decorative frame 400 so that a gap is formed between the chassis 510 and 520 and the reflector 700 that is attached to the radiator 100 through the light projection opening 401 of the decorative frame 400. Is done. Thereby, the reflector 700 can be attached to the heat radiator 100 without being obstructed by the chassis 510 and 520.

  Further, the chassis 510 and 520 include pressing members 511 and 521 used when the lighting device 1 is installed in a ceiling. When the lighting device 1 is embedded and installed in the ceiling, first, the pressing members 511 and 521 are inserted into the embedded holes in the ceiling wall and pushed up until the annular flange 410 contacts the ceiling. Thereafter, the pressing members 511 and 521 sandwich the ceiling wall with the annular flange 410, so that the lighting device 1 is embedded in the ceiling.

  The reflector 700 is made of, for example, a synthetic resin such as an ABS resin or a metal such as an aluminum die cast, and is formed in a cylindrical shape with both upper and lower ends opened in a substantially circular shape (see FIG. 5). The reflector 700 is inserted from the opening of the decorative frame 400 and fixed by inserting fixing springs 704 and 705 described later through the notches 104 and 105. The reflector 700 is removed when the fixing springs 704 and 705 are detached from the notches 104 and 105. A specific fixing method of the reflector 700 will be described later.

  The reflector 700 adjusts the light distribution by reflecting the light emitted from the light emitting module 600. Specifically, since the light emitted from the light emitting surface of the light emitting module 600 passes through the opening of the reflector 700, the irradiation direction is adjusted by the cylindrical shape of the reflector 700 (see FIG. 5).

  An example of the appearance of the reflector 700 will be described. FIG. 3 is a diagram illustrating an example of the appearance of a reflector. As shown in the example of FIG. 3, the reflector 700 includes a mounting bracket 701 and a reflector 702.

  As will be described later, when the threaded portion of the mounting bracket 701 and the threaded portion of the reflector 702 are threaded, the mounting bracket 701 and the reflector 702 are integrated as shown in FIG.

  Also, as shown in FIG. 3, the mounting bracket 701 is provided with two spring support members 703 at positions facing each other. The spring support member 703 is a member that rotatably supports the fixed springs 704 and 705.

  The fixed spring 704 is an elastic member and has an extending portion 704a extending in two directions. Similarly, the fixed spring 705 is an elastic member and has an extending portion 705a extending in two directions. Here, a method of fixing the reflector 701 to the radiator 100 using the fixing springs 704 and 705 will be described with reference to FIGS. 3 and 4. FIG. 4 is a diagram illustrating an external appearance example of the lighting device 1 before the reflector 700 is attached. First, a force is applied to the two extending portions 704a in a direction in which the two extending portions 704a approach each other. If it carries out like this, the two extending | stretching parts 704a will deform | transform and become a magnitude | size which can be inserted in the notch 104 shown in FIG. In this state, the two extending portions 704a are inserted into the notch 104. Similarly, the two extending portions 705a are inserted through the notch 105. When the force applied to the extending portions 704a and 705a is loosened, each of the two extending portions 704a spreads in a direction away from each other and is supported by the member 106, and each of the two extending portions 705a moves away from each other. And is supported by the member 106. Therefore, the reflector 701 is pressed against the radiator 100 by the extending portions 704 a and 705 a and the member 106. As a result, the reflector 700 is fixed to the radiator 100 as shown in FIGS.

  As described above, in the lighting device 1 according to the embodiment, the extending portion 704a, 705a is not supported by the member provided outside the lighting device 1, but the extending portion is connected to the member 106 provided in the radiator 100. 704a and 705a are supported. Therefore, according to the illuminating device 1 which concerns on embodiment, the position of the reflector 700 can be accurately fixed with respect to the heat radiator 100. FIG. As a result, according to the illuminating device 1 which concerns on embodiment, the position of the reflector 700 can be accurately fixed with respect to the light emitting element provided in the heat radiator 100.
