Definitions

  • the LED flood light provided by the utility model comprises a light board and a convex lens, the light board is installed at the end of the LED flood light, the convex lens is mounted on the opening of the front end of the LED flood light, and the geometry of the convex lens The center is on the same line as the geometric center of the light panel, the light panel is parallel to the convex lens, and the light panel is trapezoidal.
  • the LEDs on the lamp panel are arranged in an equal difference from top to bottom.
  • the LEDs of the equidistant arrangement are distributed according to the attenuation of the light on the surface to be illuminated, so that the illumination value of the LED can be more evenly distributed on the surface to be illuminated.
  • the utility model provides the beneficial effects that by adding a convex lens at the front end of the LED floodlight, the LED floodlight can be refracted by the LED light, and the trapezoidal light panel can be used.

Abstract

L'invention concerne une lampe de projection de lumière à LED qui se rapporte au domaine de l'éclairage à LED et comprend une carte de lampe (1) et une lentille convexe (4). La carte de lampe est installée à l'extrémité arrière de la lampe de projection de lumière à LED; la lentille convexe est installée dans une ouverture à l'extrémité avant de la lampe de projection de lumière à LED; le centre géométrique de la lentille convexe et le centre géométrique de la carte de lampe se trouvent sur la même ligne; la carte de lampe et la lentille convexe sont parallèles; et la carte de lampe est trapézoïdale. La lampe de projection de lumière à LED présente les avantages que grâce à l'ajout de la lentille convexe à l'extrémité avant de la lampe de projection de lumière à LED, il devient possible que la lampe de projection de lumière à LED peut réfracter les rayons de lumière de LED. Grâce à la coopération de la carte de lampe trapézoïdale, il est possible d'éclairer avec précision une zone rectangulaire à éclairer dans le cas où un angle est formé par la lampe de projection de lumière et la zone à éclairer.
