【考案の詳細な説明】 〔技術分野〕 この考案は照明器具に関するものである。[Detailed explanation of the idea] 〔Technical field〕 This invention relates to lighting equipment.
非常灯、スポツトライト、ダウンライト等では
高精度の配光が要求されることがある。
Emergency lights, spot lights, downlights, etc. may require highly accurate light distribution.
ところで、従来のダウンライトにおいて、第１

As shown in the figure, the frame 1 was attached to the main body 3 of the appliance by means of a stiff spring 2, and the reflector plate 4 was held by a pair of bending springs 6 protruding from the lamp socket 5. 7 is a ceiling material, and 8 is a lamp.

という欠点がある。 However, since the bending spring 6 protrudes to the side of the lamp 8, there is a drawback that the lamp light is blocked. In addition, when the reflector plate 4 is attached to the bending spring 6, the reflector plate 4 may be deformed, the spring 6 may be plastically deformed, or due to dimensional variations, etc., the lamp 8
The vertical position of the reflector 4 is not stable with respect to the
Therefore, there is a drawback that the control angle θ of the lamp light changes. Furthermore, although the frame 1 is held in contact with the surface of the ceiling material 7, the resting position changes vertically due to the unevenness of the surface of the ceiling material 7, and the position of the center hole 9 of the frame 1 changes in the vertical direction. However, the control angle θ of the lamp light changes, and a highly accurate and stable light distribution cannot be obtained.
したがつて、この考案の目的は、遮光がなくし
かも高精度かつ安定な配光を得ることができる照
明器具を提供することである。
Therefore, the purpose of this invention is to provide a lighting fixture that does not block light and can provide highly accurate and stable light distribution.

This idea involves installing a lamp socket in the main body of the device so that it can move freely in the vertical direction, while also providing a reflector on the frame that is attached to the main body of the device using a tight spring. It is supported on the surface of Since the conventional bending spring is not required, there is no light shielding, and since the reflector comes into contact with the lamp socket, the position of the reflector relative to the center of the lamp is stabilized without being affected by unevenness on the surface of the ceiling material.

る。反射板１９の天部にはランプ２２を通すラン
プ挿通孔２３を形成している。 An embodiment of this invention is shown in FIGS. 2 and 3. That is, 10 is a ceiling material, 11 is an embedding hole thereof, and 12 is a device main body. A socket support 15 is provided at the top of the appliance body 12, and a lamp socket 16 is provided at the bottom thereof so as to be slidable in the vertical direction. The frame body 17 has a reflective plate 1 in the center hole 18.
9 are integrally provided, a pair of tightening springs 20 are provided on both sides of the frame 17, and the tips of the tightening springs 20 are hooked on a receiving fitting 21 attached to the inner surface of the instrument body 12. A lamp insertion hole 23 through which the lamp 22 passes is formed in the top of the reflection plate 19.
枠体１７を押上げると反射板１９の天部がラン
プソケツト１６の下面に当接し、さらに押上げる
とランプソケツト１６がともに上方に移動すると
ともに枠体１７が天井材１０の表面に当接した位
置でキツクばね２０の保持力で係止状態となる。 When the frame 17 is pushed up, the top of the reflector 19 comes into contact with the lower surface of the lamp socket 16, and when it is pushed up further, both the lamp sockets 16 move upward and the frame 17 comes into contact with the surface of the ceiling material 10. The locking state is achieved by the holding force of the tight spring 20.
このように構成したため、従来のようなランプ
遮光がなく、また反射板１９とランプ２２との位
置関係はランプソケツト１６の下面で決定され、
天井材１０の表面凹凸の影響を受けないので、ラ
ンプ光の制御角が高精度に安定する。 With this configuration, there is no lamp light shielding as in the conventional case, and the positional relationship between the reflector 19 and the lamp 22 is determined by the lower surface of the lamp socket 16.
Since it is not affected by surface irregularities of the ceiling material 10, the control angle of the lamp light is stabilized with high precision.
なお、ランプソケツト１６はキツクばね２０よ
りも弱い力のばねで下方向に付勢されてもよい。
またソケツト支持体１５がランプソケツト１６と
一体になり、ソケツト支持体１５が器具本体１２
に対し上下移動自在に構成されてもよい。 Note that the lamp socket 16 may be biased downward by a spring with a force weaker than that of the tight spring 20.
Further, the socket support 15 is integrated with the lamp socket 16, and the socket support 15 is integrated with the appliance main body 12.
It may also be configured to be movable up and down.
以上のように、この考案の照明器具によれば、
従来に比して光の有効利用が図れ、ランプ光の制
御角が高精度に安定するという効果がある。
As mentioned above, according to the lighting equipment of this invention,
This has the effect of making more effective use of light than in the past, and stabilizing the control angle of the lamp light with high precision.
