DETAILED DESCRIPTION OF THE INVENTION
(11) Provided is a thin fire rate rated recessed light fixture.
(12) The top of the body 1 is closed. The center part of the body 1 can have a downwardly depression. The depression can be circularly shaped other than fora portion where the wire leaves the body 1. The body 1 can have fastener openings on top for attaching clip holder 8 and wire guide 10.
(13) A circular LED board 2 configured to rest on one of its sides is placed inside of body 1 against the sidewall of the body 1. Reflective paper 4 rests below and against a depression on the top of the body 1. LED lights sources 3 are placed on the inner side of the LED Board 2.
(14) Light guide 5 which is typically made from transparent glass or plastic that is placed directly, in front of the LED light sources 3. The body 1 is circular and can have a height of 15 mm to 22 mm, such as 17 mm to 20 mm, such as 18.5 mm. The depression can have a height of 3 mm to 7 mm, such as about 5.5 mm.
(15) The light from the LED light sources 3 travels to inside of the light guide 5 from the sides of the light guide 5. The light then leaves the light guide 5.
(16) A lens 6 is placed below the light guide 5. The diffuser lens 6 can be made from plastic or glass. The diffuser lens 6 can be a translucent or semi-transparent cover that spreads out or scatters light. The diffuser lens 6 can control brightness and give off a soft light.
(17) A ring 7 is placed below the lens 6. The ring 7 can be made from a non-metallic material such as plastic with a high melting point, and is pushed against inside of body 1. The plastic can have high tear and tensile strength, and resistant to high temperatures. The ring 7 can be manipulated by hand (the plastic is not rigid), and is stretchable. The ring 7 is attached tightly without a fastener to inside of the body 1, and keeps the components of the body 1 inside of the body 1.
(18) The top of the body 1 can have two openings on opposite sides for attachment of clip holders 8. Clips 9 can be attached to clip holder 8. Each clip 9 can have a spring for keeping the clip 9 in place. The clip holder 8, clip 9 and its spring, as well as all the fasteners can be made from steel and be resistant to melting in the event of a fire.
(19) The top of the body 1 can have a circular depression, all along or partially on top of the body. As illustrated, the top of the body 1 has a partially circular depression. The non-circular portion that curves inwardly is positioned next to where a wire comes out of the body 1. An opening exists on top of the body 1 for a wire come out. Wire guide 10, which can be made from steel, is fastened to two openings on the body 1, and covers the wire opening and the wire.
