Abstract
Packaged LEDs with phosphor films, and associated systems and methods are disclosed. A system in accordance with a particular embodiment of the disclosure includes a support member having a support member bond site, an LED carried by the support member and having an LED bond site, and a wire bond electrically connected between the support member bond site and the LED bond site. The system can further include a phosphor film carried by the LED and the support member, the phosphor film being positioned to receive light from the LED at a first wavelength and emit light at a second wavelength different than the first. The phosphor film can be positioned in direct contact with the wire bond at the LED bond site.
Claims20
A method for manufacturing an LED assembly, comprising:
- mounting an LED to a support member;
- electrically connecting the LED to the support member with a wire bond;
- heating a self-supporting pre-shaped phosphor film;
- applying the heated self-supporting pre-shaped phosphor film to the wire bond, the LED and the support member such that the phosphor film deforms around and completely surrounds the wire bond without changing a location and/or shape of the wire bond;
- and
- curing the phosphor film.
A method for manufacturing a plurality of LED assemblies, comprising:
- mounting a plurality of LEDs to a wafer;
- electrically connecting the plurality of LED to the wafer with a corresponding plurality of wire bonds;
- heating a self-supporting pre-shaped phosphor film;
- applying the heated self-supporting pre-shaped phosphor film to the plurality of wire bonds, the plurality of LEDs and the wafer such that the phosphor film deforms around and completely surrounds each of the plurality of wire bonds without changing a location and/or shape of the plurality of wire bonds;
- and
- curing the phosphor film.
