Phosphor distribution for helical compact fluorescent lamp |
摘要 |
A compact fluorescent lamp is provided in a coiled or helical configuration in order to maximize the length of discharge tubing for a given height. A non-uniform coating of phosphor is provided on the interior surface of the discharge envelope to inhibit light otherwise directed inwardly into the lamp toward a longitudinal axis of the helical configuration and redirect the light outwardly through an outer circumferential portion having a thinner phosphor coating. This results in increased light output for an given lamp geometry and lamp power.
