LIGHTING DEVICE
First Claim
1. A lighting device (1) comprising:
- a. one or more light sources (10) arranged to generate light (11);
b. an accommodating device (5) having an external boundary (2) which is at least partly translucent and is arranged to accommodate the one or more light sources (10); and
c. a controller (40) connected to the one or more light sources (10);
whereina first part (21) of the external boundary (2) and the one or more light sources (10) are arranged to provide at least part of the light (11) through the first part (21) of the external boundary (2), thereby providing a first flux of a first type of light (111), the first type of light (111) having a color and a first luminous intensity;
a second part (22) of the external boundary (2) and the one or more light sources (10) are arranged to provide at least part of the light (11) through the second part (22) of the external boundary (2), thereby providing a second flux of a second type of light (112), the second type of light corresponding to white light and having a second luminous intensity; and
the controller (40) comprises a trigger input for receiving a trigger signal and is arranged to increase the first luminous intensity of the first type of light (111) after receiving the trigger signal, wherein the color of the first type of light (111) initially has a dominant wavelength in the range of 580 to 770 nm, and to subsequently increase the second luminous intensity of the second type of light (112).

Abstract
The invention provides a lighting device (1) comprising one or more light sources (10) arranged to generate light, an accommodating device (5) having an external boundary (2) which is at least partly translucent and is arranged to accommodate the one or more light sources and a controller (40). The lighting device can generate two types of light. One or more lighting parameters selected from the group consisting of the first luminous intensity of the first type of light, the second luminous intensity of the second type of light, the color point of the first type of light and the color point of the second type of light can be controlled. This allows task lighting and atmosphere lighting. The invention is also directed to a method of providing a wake-up stimulus by means of such a lighting device.
