  • the lighting fixtures used in the market such as fluorescent lamps, tungsten lamps, and energy-saving bulbs currently accepted by the public, have been widely used in daily life.
  • such lighting fixtures have fast light attenuation, high energy consumption, high heat generation, short service life, easy breakage, and difficulty in recycling, and the conventional fluorescent lamps have poor color rendering properties, and the current is unstable and is likely to cause flicker.
  • the combination of Light Emitting Diode (LED) lighting fixtures that have emerged in the past decade has overcome the above drawbacks to some extent.
  • the combined LED lighting fixture is composed of a multi-point light source, and when the multi-point light source directly illuminates the object, the light emitted by the soft reflection of the lampshade is easy to cause multiple shadows on the illuminated object, thereby causing glare. The situation and multiple shadows occur.
  • a high-power LED with a light guide column structure so that the high-power LED is illuminated toward the left and right ends of the light guide column, so that the light guide column is entirely illuminated, resulting in a relatively large area of soft light.
  • the utility model comprises a linear light source (LED light source) which is arranged by arranging light-emitting diode chips, wherein at least one columnar light guide body is arranged in the vicinity of the linear light source, wherein one side of the columnar light guide body is a light receiving surface, and the other side is a light emitting surface.

  • the LED chip is placed close to the surface of the arc, that is, placed at the focus, only the component perpendicular to the axial direction is concentrated by the arc section, and a uniformly projected surface light source is formed, and then projected on the front plane target. A strip of illuminated area.
  • the traditional luminaire uses the design of the reflector behind the light source to soften, concentrate or directionalize the light distribution in the illumination area, the characteristics of the LED light source that is emitted forward are completely unsuitable, so it must be between the LED light source and the target. That is, the addition of additional optical components in front of the LED light source or changing the characteristics of the cylindrical light guide refractive refraction to adjust the distribution of its optical domain can meet the needs of different illumination purposes.

Abstract

Un dispositif de source lumineuse de type à régulation comprend une source lumineuse linéaire conçue grâce à l'agencement de puces à DEL (20). Au moins une colonne de guidage de lumière (30) est disposée à côté de la source lumineuse linéaire. Un côté de la colonne de guidage de lumière est une surface de réception de lumière (32) et un autre côté est une surface d'émission de lumière (31). Le dispositif de source lumineuse présente une répartition de lumière continue et ne génère pas de lumière éblouissante.
