Patent number: 8390196Abstract: The invention provides a metal halide lamp having a ceramic discharge vessel, wherein the discharge vessel has a spheroid-like shape with a length L1 and a largest outer diameter d2, the discharge vessel further having curved extremities and openings at the curved extremities which have a curvature r3. The discharge vessel has an aspect ratio L1/d2 of 1.1??L1/d2??2.2 and a shape parameter r3/d2 of 0.7?r3/d2?1.1. This lamp has the advantage that it can be operated at a relatively high power. Furthermore, the lamp has a relatively high efficacy. Moreover, the lamp can be operated horizontally and vertically, i.e. it can be qualified for universal burning.Type: GrantFiled: April 16, 2008Date of Patent: March 5, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Josephus Theodorus Van Der Eyden, Oscar Gerard Stappers, Jacobus Johannes Franciscus Gerardus Heuts

Patent number: 6688753Abstract: The lighting unit comprises a first lighting element (10) and a second lighting element (11). In operation, the first lighting element (10) has a comparatively high light output. The second lighting element (20, 20′) has a light output, in operation, which is relatively low in comparison with that of the first lighting element (10). The lighting unit comprises a control mechanism (40) including a switching means with a toggle function that is responsive to sequential switches in the power applied to the lighting unit. By selecting the proper switching sequence, either the first lighting element or the second lighting element or both lighting elements are switched on. Preferably, the first lighting element is a compact fluorescent discharge vessel (10), and the second lighting element comprises a plurality of LEDs (20, 20′). The lighting unit enables remote-controlled switching between orientation light (night lamp) and normal light, using the toggle function in the lighting unit.Type: GrantFiled: January 31, 2002Date of Patent: February 10, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Georges Marie Calon, Josephus Theodorus Van Der Eyden, Annemarie Paulien Buddemeijer-Lock
