METHOD OF LIGHT DISPERSION AND PREFERENTIAL SCATTERING OF CERTAIN WAVELENGTHS OF LIGHT FOR LIGHT-EMITTING DIODES AND BULBS CONSTRUCTED THEREFROM

摘要

A method for preferential scattering of certain wavelengths of light and/or dispersing light in an LED or LED bulb. The method includes emitting light from at least one LED die, and scattering the light from the at least one LED die by dispersing a plurality of particles having a size a fraction of at least one dominant wavelength of the light from the at least one LED die in the LED outer shell or in an LED bulb or in an at least one shell of an LED bulb. Alternatively, the method includes emitting light from the at least one LED die, and dispersing the light from the at least one LED die by distributing a plurality of particles having a size one to a few times larger than a dominant wavelength of the light from the LED in an outer shell, or body of the LED bulb.
