  • Low-pressure mercury vapor discharge lamp with amalgam
    Patent number: 8018130
    Abstract: The invention relates to a lamp system comprising a low-pressure mercury vapor discharge lamp having a discharge vessel (6) enclosing a discharge space (8), with two electrodes (10, 30) positioned in the discharge vessel and an amalgam (18) arranged at a first end section (28) outside the discharge path between the first electrode and the second electrode. A ballast generates an electrical discharge current independently of an electrical heating current. A heating element (22) is positioned in the first end section for heating the amalgam using the electrical heating current. The temperature of the amalgam can be kept within its optimal temperature range for a relatively broad range of operating conditions.
    Type: Grant

  • Lamp assembly
    Patent number: 7878688
    Abstract: The invention relates to a lamp assembly (1) for illuminating a surface (S) comprising a chamber (3) accommodating a plurality of light-emitting diodes (11R, 11G, 11B) capable of emitting visible light. The lamp assembly comprises diffusing means (12) capable of diffusing said visible light of said light-emitting diodes to produce diffuse light (D), and said chamber further accommodates collimation means (5) arranged to collimate at least a portion of said diffused light for illuminating said surface. The lamp assembly is especially suitable for ambiance and atmosphere lighting applications.
