Abstract
Traditional incandescent and halogen lamps produce a high CRI warm white light with indirect emission patterns at the cost of poor energy efficiency. This new advancement in solid-state lighting enables the production of a new solid-state filament wherein the tungsten filament is replaced with an array of high efficiency LED emitters which combine through an equiangular spiral, or t-spline/TNURCC lightpipe network to produce a single homogeneous blue light source which then pumps a luminescent filament comprised of a phosphor loaded silicone, phosphor loaded polymer, a lanthanide doped fluoro-phosphate glass, glass ceramic tape, quantum dot filled composite, or super-continuum spectrum producing photonic crystalline structure.
Claims37
A solid-state luminescent filament lamp comprising:
- a. a luminescent glass envelope structure;
- b. a source filament emitting device housed within the luminescent glass envelope structure;
- c. a wavelength conversion shell or envelope structure connected to the source filament;
- d. a lightpipe network comprised of high efficiency, low absorption glass, polymer, or photonic crystalline holey fiber structure which guides light from the source array and then injects light into the luminescent glass envelope structure and connected to the wavelength conversion shell;
- e. a waveguide combining light from a spider of source locations, or to direct and guide through high efficiency TIR the light from a central lightpipe trunk illuminated by a large emitter or emitter array housed within the luminescent glass envelope structure or coupled to the encapsulant immersing the source array and connected to the lightpipe network;
- f. thermal dissipation structures attached to the source array package structure creating an enclosed area;
- g. a base attached to the thermal dissipation structures;
- and
- h. a power electronics device converting line AC to a stabilized power factor corrected DC to drive the solid-state emitter devices located within the base.
