The invention relates to a method for making a thin finished product to be formed by deformation that combines strength with resistance to a highly corrosive environment. The method comprises forming a sheet of stainless steel with a microstructure consisting predominantly of ferrite, austenite, martensite or a mixture thereof, with a thickness of less than 3 mm, to a three dimensional semi finished product, treating said semi finished product with a nitrogen-containing atmosphere at a temperature of between 1000° C. and 1200° C. during a time and under a nitrogen pressure, sufficient to saturate the product through the thickness with a nitrogen content between a lower limit of 0.3 wt % and an upper limit that is provided by the beginning of nitride separation, cooling down said product at such a rate and nitrogen pressure that nitride separation is avoided, and subsequently machining the nitrogen saturated semi- finished product to the finished product. The invention further relates to a rotary shaving assembly prepared by the method of the invention.

The invention relates to selecting a light source from a plurality of light sources, particularly to the selecting of a light source by pointing to it with a light source selection device. An embodiment of the invention relates to a light source selection device (10) comprising—at least one photosensor (36, 38, 40) with a field of view (20, 22, 24), wherein light (26, 28, 30) from one or more light sources (32, 34) may be received by the photosensor within the field of view, and—a photosensor output signal processing unit (42) being adapted to select one or more light sources by processing the light received by each photosensor. The present invention may be for example used to select appliances or devices or objects provided with the ability to transmit coded light in the ultra violet, visible or infra red spectra, for example lights, climate, curtains, kitchenware, etc.

The invention relates to color selection input, for example by means of a color selection wheel or pad, particularly for a lighting system. The invention provides color selection means (10) representing selectable colors in terms of hue gradation (12) along a direction thereof, wherein the hue gradation is adapted to user preferences in that the hue gradation is divided into non-equal segments (20, 22) with segments of user preferred hue (20) larger than segments of non user preferred hue (22). The invention has the main advantage that the input of a color selection may be better adapted to user preferences.

A relative flux sensor (122) and a method of characterizing characteristics of light emitters are provided. The relative flux sensor (122) comprises a color point sensor (108) and a sensor color (118). The color point sensor (108) measures a color point in a color space of light emitted by a light source (101) comprising a first light emitter (102) for emitting light of a first color and a second light emitter (114) for emitting light of a second color being different from the first color. The light source (101) is arranged for emitting light of a controllable color, being a mix of light of the first color and light of the second color. The sensor controller (118) is coupled to the color point sensor (108) for receiving a measuring signal and is arranged for i) providing a first signal to the light source (101), the first signal comprising a dimming factor D1 and a dimming factor D2, the dimming factor D1 and the dimming factor D2 indicating a fraction of a maximum flux of the first light emitter (102) and the second light emitter (114), respectively, and receiving the measuring signal representing a first color point when the light source (101) emits light according to the first signal, wherein at least one of the dimming factors D1 and D2 is different from 0, ii) providing a second signal to the light source (101), the second signal comprising a dimming factor D4 and a dimming factor D5, the dimming factor D4 and the dimming factor D indicating a fraction of the maximum flux of the first light emitter (102) and the second light emitter (114), respectively, and receiving the measuring signal representing a second color point when the light source (101) emits light according to the second signal, wherein both dimming factors D4 and D5 are different from 0, iii) calculating within a model of the color 20 space a ratio between a maximum flux of the first light emitter (102) and a maximum flux of the second light emitter (114) on the basis of the first color point, the second color point, the dimming factors D1, D2, D4 and D5.

The present invention relates to a control unit (108) for a lighting system (100) comprising at least two individually controllable light sources (102, 104), wherein the control unit (108) is connectable to the at least two individually controllable light sources (102, 104) and configured to control the at least two individually controllable light sources (102, 104), wherein the control unit (108) is further configured to control a first lighting system configuration comprising the at least two individually controllable light sources (102, 104) so as to cause it to emit a first illumination pattern (120) provided jointly by the at least two light sources (102, 104) of the first lighting system configuration, detect and store an initial set of illumination parameters being indicative of the first illumination pattern (120), determine a subsequent set of illumination parameters being indicative of a second illumination pattern (122) provided by a second lighting system configuration comprising individually controllable light sources (102, 106), the second lighting system configuration being different from the first lighting system configuration, and control, in dependence on the initial set and the subsequent set of illumination parameters, the second lighting system configuration so as to cause it to emit a third illumination pattern (124), the third illumination pattern (124) being an approximation of the first illumination pattern (120). The present invention provides advantages in respect of e.g. automatic “healing” of the lighting system (100), for example in the case where a light source (102, 104) of the lighting system (100) fails or is only capable of providing less than the normal rated light output.

The invention relates to a control device for controlling the hue of light emitted by a light source. The control device comprises a hue selection surface capable of displaying one or more hues available for said light of said light source and interaction detection means for detecting interaction between said hue selection surface and a user of said control device in selecting said hue for said light of said light source. The control device allows the user to select the desired hue for the light source simply by interacting with the hue selection surface that displays the available hues. Consequently, the control device can be operated easily and intuitively.

The present invention provides a lighting system with a color indicator surface (24, 30). The surface receives light via a cover (18) of the lighting system, mainly through internal reflection. Hence, the light from the light sources, here at least two different colored LEDs (14), is guided away from the main light emitting surface (20), such that well-mixed light with a lower intensity may be used to determine the color of the light. The color indicator surface may be a surface (24) of the cover (18), or may be a surface (30) of a separate outer part (26). The lighting system may be used to illuminate objects in houses, shops and so on. The color indicator surface provides a convenient and easily accessible color reference.
