Abstract
A light box (10), for illuminated advertising, has at least one transparent front face (FS), which is illuminated by at least two lamps, includes at least two lighting devices (La1, La2), at least two operating devices (BG1, BG2) for operating each lighting device (La1, La2), wherein the operating devices (BG1, BG2) each have a first interface (IN11, IN12) and the first interfaces (IN11, IN12) are connected to each other and to a control device (SG). Two different sensors (SE1, SE2) are connected to the control device (SG) and the lighting devices (La1, La2) are actuated by the operating devices (BG1, BG2) according to the control signals received via the first interface (IN11, IN12).

Method for illuminating a light box (10) for illuminated advertising, having at least two lighting devices, wherein
- at least two lighting devices (La1, La2), each being operated by an operating device (BG1, BG2),
- the operating devices (BG1, B2) are connected to each other through an interface (IN11, IN12),
- a control device (SG) which is connected with both operating devices (BG1, BG2) through the interface (IN11, IN12),
- at least two different sensors (SE1, SE2) connected with the control device (SG),
- wherein the control device (SG) transmits control signals through the first interface (IN11, IN12), which depend on the sensor signals detected by the sensors and which control the lighting devices (La1, La2) depending on the control signals received through the first interface.
Light box (10), for illuminated advertising, having at least one transparent front side (FS) which is illuminated by at least two lighting devices, comprising:
- at least two lighting devices (La1, La2),
- at least two operating devices (BG1, BG2), each operating one lighting devices (La1, La2), wherein each of the operating devices (BG1, BG2) is equipped with a first interface (IN11, IN12) and the first interfaces (IN11, IN12) are connected with each other and with a control device (SG), wherein two different sensors (SE1, SE2) are connected with the control device (SG) and the lighting devices (La1, La2) are controlled by the operating devices (BG1, BG2) depending on the control signals received through the first interface (IN11, IN12).
A method for illuminating a light box (10), for illuminated advertising, having at least one lighting device (La1), the method comprising:
- arranging at least one sensor (SE1) in the light box (10),
- detecting, via the sensor (SE1), a sum of artificial light and ambient light,
- deactivating the artificial light and performing a measurement, via the sensor (SE1), during the deactivated period,
- adjusting the lighting with respect to brightness.
Light box (10), for illuminated advertising, comprising at least a transparent front side (FS), which is illuminated by at least one lighting device (La1), and at least one sensor (SE1), wherein the sensor (SE1) detects a sum of artificial light and ambient light, the artificial light is deactivated and a measurement is performed by the sensor (SE1) during deactivation, the illumination is correspondingly adjusted with respect to brightness.
