Abstract:
An LED bulb having bulb-shaped shell and thermally conductive fluid or gel within the shell. The bulb includes at least one LED within the shell. The bulb includes at least one LED within the shell and a base. The base can be configured to fit within an electrical socket and can include a series of screw threads and a base pin, wherein the screw threads and base pin are dimensioned to be received within a standard electrical socket. Alternatively, the base can be configured to fit within a suitable electric socket.
Abstract:
An LED light source is described. The light source includes an LED and a diffuser. The LED emits a light having a dominant wavelength. The diffuser includes a filler material, which includes particles. The mean diameter of the particles is at least as large as the dominant wavelength of the light emitted by the LED. The particles are configured to scatter the light emitted by the LED.
Abstract:
A light emitting diode (LED) bulb configured to scatter certain wavelengths of light. The LED bulb includes a base having threads, a bulb shell, at least one LED, and a plurality of particles disposed within the bulb shell. The plurality of particles has a first and second set of particles. The first set of particles is configured to scatter short wavelength components of light emitted from the at least one LED and has particles with an effective diameter that is a fraction of the dominant wavelength of the light emitted from the at least one LED. The second set of particles is configured to scatter light emitted from the at least one LED, and has particles with an effective diameter equal to or greater than the dominant wavelength of the light emitted from the at least one LED.
