Abstract
A light modifying material composed of ethylene/butene-1 copolymer or propylene homopolymer or a combination of the two, and lighting devices using the material in a light transmitting cover (20). It is preferred that the light source (10) for the devices is a semiconductor or light emitting diode (LED), to produce an energy efficient light source.
Claims16
A lighting device comprising:
- a power source electrically connected to a light source;
- and
- a light transmitting cover for the light source made from a polyolefin composed from a combination of ethylene/butene-1 copolymer and propylene homopolymer.
A lighting device comprising:
- a power source electrically connected to a light source;
- and
- a light transmitting cover for the light source made from ethylene/butene-1 copolymer wherein the cover is clear.
A lighting device comprising:
- a power source electrically connected to a light source;
- and
- a light transmitting cover for the light source made from a polyolefin from the group consisting of ethylene/butene-1 copolymer and propylene homopolymer, wherein the cover is additionally composed of a clarifying agent.
A lighting device comprising:
- a light source;
- a cover for the light source made from a plastic composed from a combination of ethylene/butene-1 copolymer and propylene homopolymer;
- a power source electrically connected to the light source;
- and
- an electronic circuit to cause the light source to flash when electrically connected to the power source and light source.
A lighting device comprising:
- a base;
- an LED;
- a cover;
- composed of a polyolefin from the group consisting of ethylene/butene-1 copolymer and propylene homopolymer
- wherein said base is attached to said cover, forming a bulb, and said LED is electrically connected to said base and contained within the bulb.
A clear light transmitting material formed by heating a ethylene/butene material above 140 degrees F., and rapidly cooling said material by bathing the material in cold water.
A light transmitting material composed of a combination of an ethylene/butene-1 copolymer and a propylene homopolymer.
