Abstract
Optical components may be made with reflectors that increase the reflectivity of the resulting device. Increasing in the reflectivity may reduce the need for higher power light sources. In particular, the use of deposited silver layers may dramatically increase the reflectivity compared to aluminum and copper alloys. In addition, an absorptive layer may be positioned over the reflective layer to reduce the amount of blue light output from the reflector. This blue light absorber may be used to automatically rebalance light sources that produce an excessive proportion of blue light.
Claims30
A reflector comprising:
- a reflective layer;
- and
- an absorbing layer that preferentially absorbs blue light, said absorbing layer being located over said reflective layer.
A method comprising:
- forming a reflective layer;
- and
- forming an absorbing layer over said reflective layer that absorbs a particular wavelength of light.
A reflector comprising:
- a silicon substrate;
- and
- a silver layer formed directly on said silicon substrate.
A method comprising:
- depositing silver on a silicon substrate at a temperature less than 50° C.;
- and
- forming an absorbing layer over said silver.
