LED luminarie for use in dairy barns
First Claim
1. A LED luminaire (10) for use in a livestock barn, comprising:
- a luminaire body with a base plate (13);
a first LED arrangement comprising a first electronics board (23, 25) mounted to the base plate and a plurality of LEDs mounted to the first electronics board (23, 25), the LEDs mounted to the first electronics board (23, 25) being only of a first type (28) having at least one peak wavelength in a wavelength range between 500 and 600 nm, wherein the LEDs of the first type (28) are each a white LED;
a second LED arrangement comprising a second electronics board (21, 22, 24) mounted to the base plate and a plurality of LEDs mounted to the second electronics board (21, 22, 24), the plurality of LEDs mounted to the second electronics board (21, 22, 24) comprising i) a plurality of white LEDs having at least one peak wavelength in a wavelength range between 500 and 600 nm and ii) at least one LED of a second type (27), the second type LED being a blue LED with a peak wavelength in a wavelength range between 440 and 480 nm;
a first driver operatively connected to the first LED arrangement, the first driver providing power to the LEDs mounted to the first electronics board (23, 25);
a second driver operatively connected to the second LED arrangement, the second driver providing power to the LEDs mounted to the second electronics board (21, 22, 24), the first driver (50) being separate from the second driver (51) and allowing the first LED arrangement to be operated independently of the second LED arrangement; and
an optical system (30) covering each LED, the optical system distributing light emitted by the LEDs according to an intensity distribution (40) with a peak intensity at an angle of more than zero degrees from an optical axis of the luminaire,wherein the optical system for creating the intensity distribution (40) is provided by each LED being comprised of a respective individual optical lens (30), the individual optical lens (30) of each LED distributing light emitted by each LED according to the intensity distribution (40) with the peak intensity at the angle of more than zero degrees from the optical axis of the luminaire.

Abstract
A LED luminaire for use in a livestock barn includes a base plate provided with at least one first LED arrangement configured to, in operation, emit light which simulates daylight lighting conditions. The first LED arrangement includes a plurality of LEDs of a first type, which has at least one peak wavelength in the wavelength range between 500 and 600 nm, and at least one LED of a second type, which is a blue LED with its peak wavelength in the wavelength range between 440 and 480 nm. The luminaire is provided with an optical system configured so that the intensity of light emitted by the LEDs is distributed according a distribution which has its peak intensity at an angle of more than zero degrees from the optical axis of the luminaire.
