  • Reflector and a method of generating a reflector shape
    Patent number: 5408363
    Abstract: A reflector for radiation disseminated by a radiation source is of a shape with which the reflector curve of intersection in a plane including an axis (A) of the reflector and the radiation source comprises segments (S1-A1, A2-B2) of different conics whose merging is edge-free. These conic segments are joined directly and the tangents at the point of contact (A1,A2) of two joined conic segments are alike. A method of generating such a reflector is indicated as well.

  • Lamp with ventilated housing
    Patent number: 5138541
    Abstract: In a lamp (10) equipped with a cold-light reflector (18) behind the cold-light reflector (18) a further reflector (32) is provided which reflects the infrared radiation onto a housing wall (14) of the lamp (10).

  • Reflector for a lamp and method of determining the form of a reflector
    Patent number: 5136491
    Abstract: A reflector for a lamp has a form which in a section containing the optical axis 1 lies between two curves enveloping the reflector section curve R. The enveloping curves may be two ellipses, two parabolas or an ellipse and a parabola.

  • Illumination equipment
    Patent number: 4956751
    Abstract: An apparatus for illumination generating artificial light which resembles natural light as much as possible comprises a light source radiating substantially in the blue-green region, such as a fluorescent lamp (16a,b,c,d) and at least one incandescent lamp (18). Prior to exiting from a housing (12) of the illumination equipment the light of the light source radiating blue-green is reflected at least once from a white wall (14). This applies also, in part at least, to the light of the incandescent lamp (18).

  • Lamp
    Patent number: 4814956
    Abstract: A lamp is provided having a light source and a suppression mechanism, for example an absorbing mirror reflector and/or an absorbing or reflecting filter, for partially suppressing color components of the light coming from the light source for the purpose of enhancing surface colors of an object to be illuminated, said surface colors being different from the suppressed color components.
