JPH11195315A - Luminaire - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a means for filling in the clearance between an aperture of a light-transmitting globe and a top plate simply and at a low cost. SOLUTION: A luminaire body 10 is provided. Light sources 22, 24 are mounted on the under surface of the luminaire body 10. A synthetic top plate 30 is detachably mounted around the luminaire body 10. A light-transmitting vase-like globe 40 which is integrally formed by blow molding of a synthetic resin and has an aperture in the upper surface is provided. Coupling means 52, 54 detachably couple the top plate 30 with the light-transmitting globe 40 to block the aperture of the globe 40 by the top plate 30. A masking edge 32 covering the coupling part from the outside is formed on the periphery of the top plate 30. The masking edge 32 is provided with elasticity and flexibility so as to fill in the clearance between the upper surface of the light-transmitting globe 40 and the masking edge 32 and to closely contact them.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting apparatus provided with a pot-shaped translucent globe integrally formed by pressure molding using a synthetic resin.

[0002]

2. Description of the Related Art An apparatus main body 10 is provided.
A light source 22/24 attached to the lower surface side of the device, a top plate 30 detachably attached to the periphery of the appliance body 10, and an opening in a pot-shaped upper surface integrally formed by pressure molding with synthetic resin. A connecting means 52 for detachably connecting the light-transmitting globe 40 with the light-transmitting glove 40 so as to close the opening 42 of the light-transmitting globe 40 with the top plate 30;
Lighting fixtures with 54 are known.

[0003]

Since the light-transmitting probe is formed by pressure molding, the shape of the peripheral edge of the opening varies. For this reason, an undesired error gap is generated between the top plate and the top plate that covers the gap. Conventionally, the error gap is left as it is, or it is closed with a packing of another part. The former case is unsightly, and the latter case requires more parts. SUMMARY OF THE INVENTION It is an object of the present invention to provide a simple and inexpensive means for closing an error gap generated between an opening of a light-transmitting probe and a top panel.

[0004]

According to the present invention, there is provided an instrument main body.
Is provided. Light sources 22 and 24 are provided on the lower surface side of the instrument body 10. A top plate 30 made of synthetic resin is detachably mounted around the instrument body 10. A light-transmitting globe 40 having an opening 42 is provided on a pot-shaped upper surface formed integrally by pressure molding with a synthetic resin. The top panel 3
A connection means 52 and 54 for detachably connecting the light-transmitting glove 40 to each other so as to close the opening 42 at 0 is provided. A shielding edge 32 is formed on the periphery of the top plate 30 to cover the connection portion from outside. The shielding edge 32 is filled with an error gap generated between the shielding edge 32 and the upper surface of the light-transmitting globe 40 to provide elasticity and flexibility enough to make the shielding edge 32 adhere tightly without any gap.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given with reference to FIGS. The illustrated lighting fixture includes a fixture main body 10. Instrument body 10
Light sources 22 and 24 mounted on the lower surface side of the camera. A top plate 30 made of synthetic resin is detachably mounted around the instrument body 10. A light-transmitting globe 40 having an opening 42 is provided on a pot-shaped upper surface integrally formed by pressure molding with a synthetic resin. A connecting means 52 for removably connecting the translucent glove 40 so that the opening 42 of the translucent glove 40 is closed by the top plate 30;
・ It has 54. A shielding edge 32 is formed on the periphery of the top plate 30 so as to cover the connection point from outside. The shielding edge 32 is filled with an error gap generated between the light-transmitting globe 40 and the upper surface, and elasticity and flexibility are provided so that the shielding edge 32 is closely adhered to without any gap. The illustrated apparatus main body 10 is of a ceiling-mounted type. Light sources 22 and 24
Is an annular fluorescent lamp. The instrument body 10 is made of metal. The top surface plate 30 mounted around it is made of a synthetic resin that can be integrally molded. The opening 42 of the translucent globe 40 is formed by cutting in a post-process after the pressure forming, but it is difficult to form an accurate circular shape. The connecting means 52 and 54 are slide fittings 52.
And a set screw 54 to be screwed therein.
The translucent glove 40 with the slide fitting 52 retracted.
, And then the tip of the slide fitting 52 is
Then, the set screw 54 is tightened and fixed to the top panel 30. The shielding edge 32 has a fin shape attached to the top panel 30 and is elastically deformed to conform to the shape near the opening 42 of the translucent globe 40.

[0006]

According to the present invention, the top plate corresponding to the opening of the light-transmitting glove 40 formed by air pressure is made of synthetic resin, and a required shielding edge is integrally attached thereto. According to this, it is possible to easily and inexpensively fill the error gap generated near the opening of the translucent glove.
