The present disclosure discloses a hybrid LED lighting method and system for chicken coops. For example, a closed or semi-open chicken coop is provided with the hybrid LED lightings including white LED beads and yellow LED beads in a mixing ratio of about 1:5 to about 5:1 in a regularly alternating manner. The average light intensity on the chicken cages' underside exposed to the light of the hybrid LED lighting is about 5 to about 30 Lux. The closed chicken coop is lit by a hybrid LED lighting every day during fattening period; the semi-open chicken coop is exposed to natural light in the daytime and lit by the hybrid LED lighting at night during fattening period. Implementation of the present disclosure improves growth of chickens, increases uniformity of chickens, and improves health and resistance to epidemic diseases.
A barton hybrid LED lightening method and a system. In an enclosed or a half-open barton (4), a hybrid LED lamp (1) is installed, which comprises white lamp beads (2) and yellow lamp beads (3) that are evenly arranged in a cross in a hybrid proportion of 1:5-5:1. Average intensity of light emitted by the hybrid LED lamp (1) to a bottom surface of a coop is 5-30 Lux; in the enclosed barton (4), the lamp is used for lightening every day in a fattening period; and in the half-open barton (1), natural light is received in daytime and the lamp is used for lightening at night in the fattening period. At two sides of the barton (4) in a length direction, windows (5) are arranged in intervals respectively and the hencoop is placed directly facing each window (5). The hybrid LED lamp (1) is installed in a distance right above a bottom of each coop. The average intensity of the light emitted by the hybrid LED lamp (1) to the bottom surface of the coop is 5-30 Lux.
A Light Emitting Diode (LED) light source control system for intelligentized layer breeding, comprises a plurality of LED lamps (30) equipped at a layer breeding place and a LED light source controller (10). Each of the LED lamps (30) comprises a red light LED and a green light LED. The LED light source controller (10) controls the LED lamps (30) to emit green light during the brooding period and the improved period of a layer; and the LED light source controller (10) controls the LED lamps (30) to emit red light during the egg producing period of a layer. The LED light source controller (10) controls the illumination intensity of the LED lamps (30) by regulating the duty ratio of an output Pulse-Width Modulation (PWM). The LED light source controller (10) controls the illumination time of the LED lamps (30) by utilizing a clock unit so as to implement different illumination time respectively during various stages of the brooding period, the improved period and the egg producing period of a layer. The system can improve the production performance of the layer effectively, realize the purpose of increasing production and emission reduction, and decrease the mortality of the layer.
phalaenopsis. This inventions adopts a technical proposal as follows: a LED fixed lighting for tissue culture of orchids is characterized in that said many red and blue LEDs will constitute several units; each unit has 3 blue LEDs and there are 8 red LEDs in elliptical or rounded patterns surrounding said 3 blue LEDs, and said 3 blue LEDs are gathered in triangular pattern, and said 8 red LEDs are separated at interval. This invention makes special arrangement of lamps and realizes adjustment of light quality and light period by turning on or turning off red LEDs and blue LEDs, and by this way, a LED mixed light which is distributed evenly and suitable for tissue culture of orchids.
