Definitions

  • the lamp is characterized in that a second signal is generated by an external component of the lamp, which is adapted to generate said signal when a transducer element is actuated.
  • the generated signal is transmitted through a communication channel, by means of the intervention of at least one emitting element and a corresponding receiving element.

  • the dissipation plate 3 is covered on its inner face with a reflective layer 6 to improve the projection of the light emitted by the LEDs 1 to the outside of the lamp 9.
  • the controllers 7 are mounted on the same support plate 2 of the LEDs 1. Naturally, the invention also contemplates the possibility that the controllers 7 are located outside the housing 1 1 of the lamp, also being connected to the LEDs 1.
  • the LEDs 1 are designed to never have to be replaced throughout the life of the lamp 9, given the longevity of said components, and for this reason they are welded in the support plate 2. However, the LEDs 1 they are very sensitive to temperature increases and if they work above the safety temperature, their useful life would be drastically reduced, reaching the point of melting instantly, so that the entire lamp should be replaced 9. To avoid In this overheating situation, the controllers 7 monitor the temperature sensors and, if it exceeds the operating safety temperature of the LEDs 1, the duty cycle of the supply pulses of the LEDs 1 is temporarily reduced, so that Stop the increase in temperature and favor the cooling of the support plate 2 and therefore of the LEDs 1. By getting the desired temperature levels of the Ia to be restored support plate 2, the duty cycle of the power pulses of the LEDs 1 is restored again.
