A new energy-efficient lighting technology, ESL (Electron-Stimulated Luminescence) has been patented by a startup company Vu1.

The technology uses accelerated electrons to stimulate phosphor to create light, making the surface of the bulb “glow”.  ESL Technology creates the same light quality as an incandescent but is more energy conserving. There is no use of the neurotoxin Mercury (Hg) in the lighting process.

In creating ESL Technology, Vu1 merged several technologies then adapted them for “lighting”.  The company uses commonly sourced, non-hazardous, commercial materials. The technology is encased in standard light bulb glass which is sourced from existing light bulb glass manufacturers. No specialized glass is required.

Safe as a lighting source, the ESL Technology fits neatly into classic light bulb shape. This eliminates the need to bend the technology into an unusual, twisted spiral shape (CFL) or have costly and heavy heat dissipation designed into the bulb housing (LED).

Key gate-keeping elements of the technology and associated manufacturing processes are patent pending.
