Problems solved by technology

[0006] However, this known luminaire has the disadvantage that the reduction of the risk of blue hazards is relatively poor, since the known work light is aimed at the comfort and improvement of visual acuity for the human eye, not at blue Hazard Risk Reduction

Embodiment Construction

[0063] figure 1 A lighting device 1 is shown, in the figure a desk lamp, comprising a light source 3 inside a housing 5 with a reflector 7, but alternatively the reflector may be absent or a diffuser, the housing being via a flexible The hinge lever 9 is connected to the base 11 . The base includes a control unit 13 , an intensity adjustment button 15 and a first control button 17 . The lighting device is connectable to mains via a cable 19 . The light source comprises a plurality of LEDs 21 comprising at least a first lighting element 23 and a second lighting element 25 . The embodiment shown in the figures also comprises at least one green-emitting LED 22 as a third lighting element and at least one orange-red emitting LED 24 as a fourth lighting element. Both the first and second lighting elements may be a single LED or a plurality of LEDs. The lighting device emits with its light source a preferably white spectral beam 31 , which is the source light tuned via the contr...

Abstract

A lighting device comprising a light source being configured to generate source light of a white light emission spectrum having a color correlated temperature (CCT) in a range of 2500-20000K and comprising a control unit being configured to control a lighting element for tuning of the source light with respect to a ratio between a first emission peak in a wavelength range of 460-490nm and a second emission peak in a wavelength range of 430-460nm. Thus a lighting device with a tunable / adjustable spectrum is provided that can switch between a first operation state of energy efficiency lighting with a blue peak in the second wavelength range of 430-460nm, but with blue hazard risk, and a second operation state of less efficient but safe, healthy lighting with a biological stimulant having a blue peak in the first wavelength range of 460-490nm.

Description

technical field [0001] The invention relates to a lighting device for emitting light with an adjustable frequency spectrum. The invention also relates to a kit of parts, a lighting system comprising such a lighting device and the use of both the lighting device and the lighting system. Background technique [0002] Light is an essential part of life and affects us in various ways—visually, psychologically, and physiologically. The most obvious effect of light on humans is to allow vision: 83% of the information we receive from the world passes through our eyes. In recent decades, much has been learned about the biological or non-imaging effects of light, for example, the identification of a new photoreceptor that resides in a cell type in the retina of the eye. It is called melanopsin and regulates the biological effects of light. When light from the eye (light perceived by the eye) reaches these cells, a complex chemical reaction occurs that generates electrical impulses...
