As shown in FIG. 2 to FIG. 5, the main body 1 is a chassis formed in a circular shape from a flat plate of a metal material such as a cold rolled steel sheet, and has a circular shape for arranging the attachment portion 6 described later in a substantially central portion. The opening 11 of the image is formed. Moreover, the step part 13 which faces the back side is formed in the outer peripheral side of the flat part 12 of the inner surface side to which the light source part 2 is attached, and the cylindrical recessed part 14 is formed. In addition, a cover receiving member to which the cover member 7 is detachably attached is disposed on the step portion 13. In more detail, the cover receiving member is a cover receiving bracket 75 and is arranged in the recess 14 formed by the step portion 13. Moreover, the elastic member 15 is provided in the back side of the main body 1. As shown in FIG.

The light source part 2 is provided with the board | substrate 21 and the some light emitting element 22 mounted in this board | substrate 21 so that it may demonstrate with reference to FIG. 6 (in FIG. Omit the illustration). The board | substrate 21 is arrange | positioned so that the four board | substrates 21 of the circular arc shape which may have predetermined width | variety dimension may be joined, and are formed in substantially circle shape as a whole. That is, the board | substrate 21 formed in substantially circle shape as a whole is comprised from four board | substrates 21 divided.

By using the board | substrate 21 divided in this way, thermal contraction can be absorbed in the division part of the board | substrate 21, and the deformation | transformation of the board | substrate 21 can be suppressed. On the other hand, although it is preferable to use the board | substrate 21 divided into several, you may use one board | substrate integrally formed in substantially circle shape.

The board | substrate 21 consists of a flat plate of glass epoxy resin (FR-4) which is an insulating material, and the wiring pattern is formed in the surface side by copper foil. In addition, a white resist layer serving as a reflective layer is provided on the wiring pattern, that is, on the surface of the substrate 21. On the other hand, when the substrate 21 is made of an insulating material, a ceramics material or a synthetic resin material can be used. In the case of a metal, a metal base substrate having an insulating layer laminated on one surface of a base plate having good thermal conductivity and excellent heat dissipation such as aluminum can be used.

The light emitting element 22 is an LED and is a surface mount type LED package. The LED package is arranged along the circumferential direction of the plurality of circle-shaped substrates 21, that is, on a plurality of rows on a substantially circumference centering on the attachment portion 6, and in this embodiment, on two rows on the inner circumference side and the outer circumference side. It is mounted. In the LED cages, light emitting colors of daytime white N and bulb color L are used, and these are alternately arranged, and adjacent light emitting elements 22 in each column are arranged at substantially equal intervals. Color adjustment is made possible by adjusting the current flowing through the daytime white and the bulb color LED packages.

On the other hand, on a specific substrate 21a (in Fig. 3, right side, in Fig. 6, upper right side), a light emitting element 22a for lighting overnight is mounted. As the light emitting element 22a, an LED package similar to the color of a light bulb in a main light source mounted in a circle shape is used. As a result, the members are commonly shared.

On the other hand, the light emitting element 22 does not necessarily need to be mounted in multiple rows. For example, you may mount in one row along the circumferential direction. The number or number of columns of the light emitting element 22 can be appropriately set according to the desired output.

The LED package is roughly composed of an LED chip disposed on a main body formed of ceramics or synthetic resin, and a translucent resin for a mold such as an epoxy resin or a silicone resin for sealing the LED chip.

In addition, LED may be made to mount an LED chip directly to the board | substrate 21, and may mount a shell type LED, and a mounting method and a form are not specifically limited.

The diffusion member 3 is a lens member, and as described with reference to FIG. 7, for example, a transparent synthetic resin having insulation such as polycarbonate or acrylic resin, and the arrangement of the light emitting element 22. It is integrally formed in a substantially circular shape along the surface, and is disposed to cover the entire surface of the substrate 21 including the light emitting element 22.

5 and 7, the lens member has two sets of mountain shapes in the circumferential direction opposite to the light emitting element 22 on the inner circumferential side portion and the outer circumferential side portion of the substantially circular shape. The constant protrusion part 31 is formed continuously. Inside the protruding jaw portion 31, a U-shaped groove 32 is formed continuously along the circumferential direction. Therefore, the U-shaped grooves 32 are arranged to face the plurality of light emitting elements 22, and the plurality of light emitting elements 22 are enclosed and covered in the U-shaped grooves 32. It is in a state.

In addition, in these protrusion parts 31, the flat part 33 extended in the width direction is formed, and the whole surface of the board | substrate 21 is covered by this.

According to the lens member configured as described above, as shown in FIG. 5, the light emitted from the plurality of light emitting elements 22 is diffused and radiated mainly in the circumferential inner and outer circumferential directions by the projection jaw 31. . That is, the light emitted from the light emitting element 22 is mainly diffused and radiated in the radial direction having the origin as the center of the circle shape at the point where the light emitting element 22 is disposed.

Therefore, it becomes possible to improve the balance of the irradiation light by the light emitted from the plurality of light emitting elements 22 by the lens member. In addition, the compactness caused by the luminance of each light emitting element 22 can be suppressed. In this case, it is preferable to set the light distribution angle by diffusion to about 120 to 160 degrees.

In addition, since the flat part 33 is formed in the diffusion member 3 and covers the whole surface of the board | substrate 21, the charging part is covered and protected by the diffusion member 3 which has reinforced insulation performance.

On the other hand, the diffusion member 3 may not be integrally formed in a substantially circle shape. For example, the substrates 21 may be formed by dividing the substrates 21 into respective ones of the substrates 21. In this case, each of the plurality of light emitting elements 22 mounted on one substrate 21 is successively covered by the diffusion member 3.

Further, the diffusion member 3 may be applied to a diffusion sheet or the like, without being limited to the lens member.

It is arrange | positioned facing the downward irradiation direction. Moreover, the back surface side of the board | substrate 21 is attached by surface contact so that the flat part 12 of the inner surface side of the main body 1 may be in intimate contact. Specifically, the diffusion members 3 overlap with each other from the front surface side of the substrate 21, and the diffusion members 3 are attached to the main body 1 by fixing means such as screws S, for example. The board | substrate 21 is sandwiched between the main body 1 and the diffusion member 3, and is pressed and fixed. That is, the board | substrate 21 and the diffusion member 3 are simultaneously fixed by one screw S. FIG.

Therefore, the board | substrate 21 is thermally coupled with the main body 1, and the heat from the board | substrate 21 is conducted to the main body 1 from the back surface side, and is radiated | emitted. On the other hand, the surface contact between the substrate 21 and the main body 1 is not limited to the case where the entire surface of the substrate 21 contacts the main body 1. Partial surface contact may be sufficient.

In addition, since the flat part 33 in the diffusion member 3 is in surface contact so as to be in close contact with the mounting surface side of the substrate 21, heat is transmitted to the diffusion member 3 from the mounting surface side of the substrate 21. It is possible to dissipate heat via the diffusion member 3. That is, it is possible to radiate heat from the front side of the substrate 21 as well.

The lighting device 4 is provided with the circuit board 41 and the circuit components 42, such as a control IC, a transformer, a capacitor, mounted in this circuit board 41, as shown to FIG. have. The circuit board 41 is formed in a substantially arc shape so as to surround the periphery of the attachment part 6, the adapter A side is electrically connected, and is connected to the commercial AC power supply via the adapter A. As shown in FIG. Therefore, the lighting device 4 receives this AC power, generates a DC output, supplies the DC output to the light emitting element 22 via a lead wire, and controls the light emitting element 22 to be lit.

Such a lighting device 4 is disposed between the attachment portion 6 and the light source portion 2, that is, the substrate 21.

As shown in FIGS. 2 and 4, the lighting device cover 5 is formed in a substantially short cylindrical shape by a metal material such as a cold rolled steel sheet, and is installed in the main body 1 so as to cover the lighting device 4. It is. The side wall 51 is inclined so as to extend toward the rear side, and the opening 53 is formed in the front wall 52 so as to correspond to the attachment portion 6. Therefore, a part of light emitted from the light emitting element 22 is reflected by the side wall 51 to the front side, and is used effectively. Further, an arc-shaped guide recess 54 is formed at the circumferential edge of the opening 53 to be recessed toward the rear side.

The attachment part 6 is an adapter guide formed in substantially cylindrical shape, and the engagement hole 61 which an adapter A passes through and engages is provided in the center part of this adapter guide. This adapter guide is arrange | positioned corresponding to the opening 11 formed in the center part of the main body 1. As shown in FIG. On the outer circumferential portion of the adapter guide, a base is formed so as to protrude from the outer circumferential portion, and electrical auxiliary parts 62 such as an infrared remote control signal receiver and an illuminance sensor are disposed on the base.

On the other hand, the attachment part 6 does not necessarily need to be a member called an adapter guide or the like. For example, it may be an opening formed in the main body 1 or the like, and the main point is a member or part to which the adapter A is engaged, facing the pinched sealing body Cb as the wiring mechanism.

The cover member 7 is formed of a material having a light transmissive property such as acrylic resin and having a milky white diffusivity and is formed in a substantially circular shape, and an opaque circular makeup cover 71 is attached to the center portion. In addition, the makeup cover 71 is formed with a light receiving window 72 having a substantially triangular translucent light so as to face the electrical auxiliary part 62. In addition, protruding pins 73 protruding in the inner surface direction are formed near the center of the inner surface side of the cover member 7.

And the cover member 7 is detachably attached to the outer peripheral edge part of the main body 1 so that the front surface side of the main body 1 containing the light source part 2 may be covered. Specifically, as shown in FIG. 8, the cover member 7 (shown in FIG. 9 to be described later) provided on the cover member 7 is rotated by rotating the cover member 7. It is provided by engaging with the cover receiving bracket 75 arrange | positioned at the recessed part 14 of the outer periphery. In addition, when the cover member 7 is removed, the cover member 7 rotates in the opposite direction as when the cover member 7 is attached, thereby releasing the engagement between the cover mounting bracket 74 and the cover receiving bracket 75. I can remove it.

In the state where the cover member 7 is attached to the main body 1 in this manner, as shown in FIG. 4, the inner surface side of the cover member 7 faces the front wall 52 of the lighting device cover 5. Contact. Therefore, heat generated from the lighting device 4 or the like can be conducted to the lighting device cover 5 and to the cover member 7 to further promote heat dissipation.

In addition, the distance between the diffusion member 3 and the cover member 7 is set to 20 to 60 mm, preferably 30 to 50 mm. Thereby, the balance of irradiation light becomes good, and the heat | fever transmitted to the diffusion member 3 from the mounting surface side of the board | substrate 21 is effectively radiated | emitted via the cover member 7.

Here, although the cover member 7 rotates and is attached to the main body 1, it is necessary to position it so that the position of the light receiving window 72 may face the electrical auxiliary component 62. As shown in FIG. For this reason, in this embodiment, the position regulation means is comprised.

This position regulating means will be described with reference to FIG. 9 is a plan view schematically showing the relative positional relationship between the rotating cover member 7 side and the main body 1 side in a fixed state.

In addition, a protruding pin 73 is provided near the center. On the other hand, on the main body 1 side, the cover receiving bracket 75 is provided in three places of the outer peripheral edge part, and the guide concave part 54 of the lighting device cover 5 provided in the main body 1 is located.

In the state shown in FIG. 9A, the protruding pin 73 is fitted to the guide recess 54 (see also in conjunction with FIG. 4). For this reason, the cover member 7 is arrange | positioned at an appropriate position, and as shown to FIG. 9 (b) by rotating the cover member 7 clockwise from this state, the protrusion pin 73 is shown. While moving along the guide concave portion 54, the cover mounting bracket 74 is engaged with the cover receiving bracket 75, and the cover member 7 is provided in the main body 1. As shown in FIG. In this state, the light receiving window 72 is positioned to face the electrical auxiliary component 62, so that, for example, the infrared remote control signal receiver can receive the control signal from the infrared remote control transmitter.

That is, in the attachment position where the light receiving window 72 is not located opposite to the electrical auxiliary component 62, since the protruding pin 73 does not fit into the guide recess 54, the cover member 7 is the main body. Position control is not possible to attach to (1).

The adapter A is electrically and mechanically connected to the hanging sealing body Cb provided on the ceiling surface C by a hanging blade provided on the upper surface side, and forms a substantially cylindrical shape, and a pair of pairs are provided on both sides of the circumferential wall.

In addition, this step portion 13 is capable of achieving the reinforcing effect of the main body 1.

Moreover, since the lighting device 4 is arrange | positioned between the attachment part 6 and the board | substrate 21, the lighting device 4 is reduced that thermal influence is received from the board | substrate 21. FIG. This is because the heat of the board | substrate 21 tends to conduct toward the outer peripheral direction of the main body 1, and to radiate heat.

In addition, since the cover member 7 is brought into surface contact with the lighting device cover 5, heat generated from the lighting device 4 is conducted to the lighting device cover 5, and further to the cover member 7. Heat dissipation.
