【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 drawings and FIG. 2, the frame 1 was attached to the main body 3 of the instrument by means of a tight 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.
しかしながら、屈曲ばね６がランプ８の側方に

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.

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 loosely fitting the mounting shaft provided at the upper end of the lamp socket into the mounting hole in the top of the appliance body, engaging its head with the mounting hole, and passing a coil spring through the mounting shaft to connect the appliance body and the lamp socket. A reflector is provided on the frame which is compressed between the lamps and attached by a tight spring, and the frame is supported on the surface of the ceiling in a state in which it is brought into contact with the lower surface of the lamp socket.
There is no need for conventional bending springs, so there is no light blocking, and since the reflector comes into contact with the lamp socket, the position of the reflector relative to the center of the lamp is stable without being affected by unevenness on the surface of the ceiling material, allowing for highly accurate control angles. can get.
Further, even if an external force is applied in the lateral direction when the frame is attached, it can be absorbed by the spring.

を形成している。 An embodiment of this invention is shown in FIGS. 3 to 5. That is, 10 is a ceiling material, 11 is an embedding hole thereof, and 12 is a device main body. A socket support 15 (constituting a part of the device main body in this invention) is provided on the top of the device main body 12, and a screw 17 serving as a mounting shaft is loosely fitted into a mounting hole 16 at the bottom of the socket support 15. The upper surface of the lamp socket 18 is screwed to the tip of the screw 17.
This lamp socket 18 has guide grooves 19 formed on both sides as shown in FIG. In addition, a guide body 23 having a pair of legs 22 guided by the guide groove 19 is slidably engaged with the lamp socket 18, and a hole 24 into which the screw 17 is loosely fitted in the center of the guide body 23 and leads are formed on both sides. A notch 25 is formed that escapes the line 20. Furthermore, screw 17
A coil spring 26 is passed through the coil spring 26, and both ends of the coil spring 26 are
3 and the rear surface of the lamp socket 18. The frame body 27 has a reflecting plate 29 integrally provided in the central hole 28, a pair of stiff springs 30 on both sides of the frame body 27, and a receiving bracket 3 attached to the inner surface of the instrument body 12.
Hook the tip of the tight spring 30 onto 1. Reflector 2

is formed.

ドして容易に傾くことができ、衝撃吸収となる。 When the frame 27 is pushed up, the top of the reflector 29 comes into contact with the lamp socket 18, and when it is pushed up further, the coil spring 26 is compressed and the tight spring 30 is released at the position where the frame 27 comes into contact with the surface of the ceiling material 10. It becomes locked by the holding force. Further, when an external force is applied in the horizontal direction during such an insertion process, the coil spring 26 is compressed as shown in FIG. 5, and the guide body 23 can slide and tilt easily, thereby absorbing shock.
このように構成したため、従来のようなランプ

ができる。 With this structure, there is no lamp light shielding as in the conventional case, and the positional relationship between the reflector 29 and the lamp 32 is determined by the lower surface of the lamp socket 18.
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. Furthermore, since the lamp socket 18 rotates together, eccentricity and damage to the lamp due to unexpected external forces can be prevented.
以上のように、この考案の照明器具によれば、
従来に比してその有効利用が図れ、ランプ光の制

ランプの偏心等を防止できるという効果がある。
As mentioned above, according to the lighting equipment of this invention,
The present invention has the advantage that it can be used more effectively than in the past, the control angle of the lamp light is stabilized with high precision, and eccentricity of the lamp due to unexpected external forces can be prevented.
