Abstract: A lighting system comprising a first light source adapted to emit light substantially only in a first predetermined spectrum in a range from 600 nm to 1400 nm, and a driver circuit arranged to provide a first pulsed current to the first light source for producing the light in the first predetermined spectrum. The driver circuit is adapted to generate multiple pulses of the first pulsed current during a first period and no pulses of current during a second period, the first period and the second period alternating with each other, and the first pulsed current has a first pulse frequency and a first duty cycle during the first period, the first pulse frequency being 100 Hz or higher, and the first duty cycle being 0.5 percent or above.

Abstract: A lighting arrangement for general lighting, comprising a first light source Oadapted to emit a first light substantially only in a first predetermined spectrum in a range from 615 nm to 690 nm, one or more driver circuits adapted to provide a first pulsed driving current to the first light source for producing the first light pulsing with a first peak radiant power in the first predetermined spectrum sufficient to induce a photo-biomodulation response in a human body, and a second light source adapted to emit a second light, the second light source being capable of emitting at least 250 lumens.

Abstract: A safety endcap assembly to be arranged at an end of an LED lamp. It has an endcap base element, an endcap cover element, a connector pin, a contact element for connecting to the connector pin to LEDs, and a switch button. The endcap cover element is moveable between a protracted position and a retracted position, and the switch button is moveable between a first position and a second position. The switch button is arranged to disconnect contact element from the LEDs when the switch button is in the first position. The safety endcap assembly further has a switch opening mechanism configured to move the switch button to the first position when a certain condition is met.
