Abstract
A molded plastic lamp component includes, in an exemplary embodiment, a first portion formed from a first material having a first heat distortion temperature, and a second portion formed from a second material having a second heat distortion temperature. The first heat distortion temperature is higher than the second heat distortion temperature.
Claims21
A molded lamp component comprising:
- a first portion formed from a first material having a first heat distortion temperature;
- and
- a second portion formed from a second material having a second heat distortion temperature, said first heat distortion temperature greater than said second heat distortion temperature.
A method of fabricating a lamp component, said method comprising:
- forming a first portion of the component from a first material having a first heat distortion temperature;
- and
- forming a second portion of the component from a second material having a second heat distortion temperature, the first heat distortion temperature higher than the second heat distortion temperature.
A method of fabricating a composite lamp component comprising:
- forming a first portion from a first material having a first heat distortion temperature, and
- molding a second portion around the first portion from a second material having a second heat distortion temperature to form a composite material lamp component, the first heat distortion temperature higher than the second heat distortion temperature.
