  • the very close to the apex of the reflector incident luminous flux is reflected back to the LED 24 and its board 26, so that it comes in this area to a certain shade. Due to the narrow shape of the board 26, the overall shading effect remains relatively low. Later, in the context of FIGS. 20a, 20b, a possibility is discussed of how the shading is further reduced.
  • the reflector wall 13 is of parabolic shape.

  • the shape of the reflector surface 13 is an elliptical shape with two focal plane planes Fi and F2.

  • the light emitted from there is focused in the second focal plane F2 arranged at a distance in front of the light exit region 16.

  • the lamellae 40 are formed in the example shown as a flat diaphragm, which are arranged parallel to the emission direction of the reflector 12. They have a certain height in the light emission direction, with which the beam angle is defined in the longitudinal direction.
  • 24 lamellae 42 are arranged on the circuit board 26 between the individual LED elements. These lamellae serve to limit the width of the light distribution in the longitudinal direction. Depending on the height, the distribution can be set as narrow as desired.
  • the fins 42 may be opaque. Particularly preferred is a reflective surface of the fins 42, in particular in conjunction with a curved cross-sectional shape of the fins 42 as shown in Fig. 16. Since the fins 42 are arranged between the LED elements 24, despite the associated limitation of the width of the radiation, an almost complete utilization of the emitted light can be achieved.

  • a further optical effect can be achieved by the use of a prism structure according to the second embodiment (FIGS. 18a, 18b).
  • the prismatic structure of the lens 18 leads to a deflection of the perpendicularly incident rays on both sides, so that the relatively wide light distribution curve shown in Fig. 18b is formed.

Laterally, the completed reflector space is completed by a flat mirror surface 46. As FIG. 21b shows, the corresponding light intensity distribution is asymmetrical. The entire luminous flux of the LED light source passes through an approximately half the size of the lamp termination as in the previously described embodiments.

Abstract

L'invention concerne une unité de lampe (10) présentant un réflecteur (12) et une zone de sortie de lumière (16). Une unité de source lumineuse linéaire (30) présentant au moins une source lumineuse LED (24) est disposée dans la zone de sortie (16), à distance de la paroi du réflecteur, de façon que la totalité du flux lumineux soit irradiée en direction de la paroi du réflecteur, et réfléchie de cette paroi dans la zone de sortie de lumière. La zone de sortie est fermée par une unité terminale de transmission (18) de manière à former une chambre de réflecteur fermée. Le réflecteur (12), l'unité terminale (18) et l'unité de source lumineuse (30) sont connectés de manière inamovible entre eux en vue de former une unité de lampe (10).
