Conventionally, as shown in FIG. 6, there is a lighting fixture in which a bowl-shaped reflector plate 52 is provided within a shade 51. The socket 54 of the lamp 53 is attached to a rib 55 protruding from the bottom surface of the shade 51. The reflective plate 52 has an opening peripheral portion 52a sandwiched and fixed between the shade 51 and the lower cover 56. The lower cover 56 is a shade 51
Fix it with mounting screws, etc.

In the lighting fixture with the above configuration, the focal position of the reflector 52 and the center of the lamp 53 are determined by the height of the shade 51, the height of the rib 55, the degree of contact with the shade 51 at the opening periphery 52a of the reflector 52, etc. There is a high possibility that the ends will be misaligned. This deviation has a significant effect on the light distribution, and the desired light distribution may not be obtained.
また、組立作業においても、セード５１に順次
ソケツト５４，反射板５２，および下カバー５６

According to the lighting device of claim (1), since the reflector and the lamp socket constituting the optical system are attached to the same cylindrical mounting member, the dimensional variations of many components do not overlap as in the conventional case. This reduces the deviation between the center of the lamp and the focal point of the reflector. Further, during assembly, the cylindrical mounting member with the socket and the reflector attached can be treated as a block and attached to the shade. Furthermore, the cylindrical mounting member prevents air heated by the lamp from flowing into the inside of the shade from the bottom opening of the reflector, thereby preventing heating of the shade. In addition, since the flange portion of the cylindrical mounting member is sandwiched between the inner flange of the lower shade and the boss of the upper shade, the contact area between the lower shade and the cylindrical mounting member is widened even if heat is transferred from the cylindrical mounting member. It can be done safely and reliably.

Since the second support springs are provided protruding in the insertion direction of the engagement protrusion at a plurality of locations in the circumferential direction of the reflector fixing metal fitting, in addition to the effect of claim (1), the engagement protrusion can be moved to the first support simply by pushing the reflector. Since it fits between the spring and the second support spring and holds the reflector, it is easy to attach and remove the reflector, and the engagement protrusion only needs to be provided on the outer circumferential surface of the reflector instead of being provided on the inside or outside. Therefore, the shape is not complicated. Since the first support spring and the second support spring that engage with the reflection plate opening side and the bottom side of the reflection plate of the reflection plate engagement protrusion, respectively, are provided on the reflection plate fixing fitting, the engagement protrusion can be moved by simply pushing the reflection plate. The reflection plate is held between the first support spring and the second support spring.

９に取付けるので、従来のように数多くの部品の
寸法ばらつきが重なることがなく、ランプ８の中
心と反射板２の焦点位置とのずれを少なくするこ
とができる。そのため、目的の配光が得やすく、
また寸法管理が行い易い。 According to this configuration, the reflection plate 2 constituting the optical system
Since the lamp and socket 7 are attached to the same cylindrical mounting member 9, the dimensional variations of many parts do not overlap as in the conventional case, and the deviation between the center of the lamp 8 and the focal point of the reflector 2 can be prevented. It can be reduced. Therefore, it is easy to obtain the desired light distribution,
Also, it is easy to manage dimensions.
組立に際しては、筒状取付部材９にソケツト７
および反射板２を取付けたものをブロツクとして
取扱つてセード１に取付けることができるので、
組立性が良い。 When assembling, insert the socket 7 into the cylindrical mounting member 9.
And the one with the reflector 2 attached can be treated as a block and attached to the shade 1, so
Easy to assemble.

筒状部２ｂの外周のみに形成すればよいので構造
が簡単になる。 After the cylindrical mounting member 9 is attached to the reflecting plate 2,
You may also do this from the opening side of the shade 1. In this case, by simply pushing the cylindrical portion 2b of the reflector 2 into the ring-shaped reflector fixing fitting 11, the engagement protrusion 13 will overcome the second support spring 11b of the reflector fixing fitting 11, and the first support spring 11a and second support spring 11b
is held between. Therefore, the reflection plate 2 can be easily attached. The reflection plate 2 can also be removed by simply pulling it out. Further, since the engaging protrusion 13 only needs to be formed on the outer periphery of the cylindrical portion 2b of the reflecting plate 2, the structure is simplified.
筒状取付部材９は、前記のようにソケツト７お
よび反射板２の取付けを行うものであるが、遮熱
部材を兼用する。すなわち、ランプ８で加熱され
た空気が反射板２の底部開口２ａから上セード１

るため安全確実にできる。 The cylindrical mounting member 9 is used to mount the socket 7 and the reflecting plate 2 as described above, and also serves as a heat shielding member. That is, the air heated by the lamp 8 flows through the bottom opening 2a of the reflector 2 into the upper shade 1.
Since the cylindrical mounting member 9 prevents the water from flowing inside the upper shade 1A, heating of the upper shade 1A is prevented.
It is safe to touch from the outside. Also lower shade 1B
Since the flange portion 9a of the cylindrical mounting member 9 is sandwiched between the inner brim of the sleeve 1B and the boss 14 of the upper shade 1A, contact between the lower shade 1B and the cylindrical mounting member 9 is prevented even if heat is transferred from the cylindrical mounting member 9. It can be done safely and reliably because the area can be expanded.
また、第５図に示すように、アーム３を連結し

きに、前方への倒れ角度の条件が良い。 Furthermore, as shown in FIG. 5, the instrument main body 16 to which the arm 3 is connected is tilted and installed on the mounting base 18. Therefore, when bending the arm adjustment knob 15, a horizontal external force F is applied. The instrument body 16 rotates around the support shaft 19. Therefore, no excessive force is applied to the mounting base 18, and the mounting base 18
8 damage can be prevented. Furthermore, since the instrument main body 16 is tilted backward, even when the instrument main body 16 is of a fixed type, the condition of the forward tilting angle is good when it is installed on an inclined surface such as a drafting table.
なお、前記実施例では筒状取付部材９に対して
反射板２を板ばね状の反射板固定金具１１で取付
けたが、反射板２を筒状取付部材９にねじ等で固
定しても良い。 In the above embodiment, the reflector 2 was attached to the cylindrical mounting member 9 using a plate spring-shaped reflector fixing fitting 11, but the reflector 2 may be fixed to the cylindrical attaching member 9 with screws or the like. .

The shade is prevented from heating and is safe to touch from the outside. In addition, since the flange portion of the cylindrical mounting member is sandwiched between the inner flange of the lower shade and the boss of the upper shade, the contact area between the lower shade and the cylindrical mounting member is widened even if heat is transferred from the cylindrical mounting member. This has the effect that it can be done safely and reliably.

ならないという効果がある。 According to the lighting device of claim (2), the bottom opening of the reflector is formed of a cylindrical part, and the engaging protrusion is provided on the outer surface of the cylindrical part, and the engaging protrusion has a side surface at the distal end of the cylindrical part and a proximal end of the cylindrical part. Since a first support spring and a second support spring that respectively engage with the side surfaces are provided on the reflection plate fixing fitting, the engagement protrusions can be connected to the first support spring and the second support spring by simply pushing the reflection plate.
It fits between the support spring and the reflector is held. Therefore, it is easy to attach and detach the reflector. Furthermore, since the engaging protrusions need only be provided on the outer peripheral surface of the reflector, the shape is less complicated than when provided on the inside and outside of the reflector.
