Problems solved by technology

[0008] However, in practice it may happen that the mains power supply is out of power for a period longer than the battery or charge storage capacitor's power duration, for example in the case of a severe power failure or power interruption that is not repaired during this period

Embodiment Construction

[0057] figure 1 The reference number 10 in the figure represents a lighting device according to an embodiment of the present invention, which is composed of a housing 11 , such as a moisture-proof or waterproof housing for outdoor use of the lighting device 10 . It should be understood that the housing 11 can eg also be designed for indoor use or can have an armored design for use as security lighting.

[0058] The housing 11 accommodates a light emitting module 12 such as a light emitting module 12 composed of, for example, a plurality of light emitting diodes LED connected in series and parallel. The lighting module 12 is powered by a driver circuit 13 in the housing 11, the power input 14 of which is electrically connected to a mains power supply, such as a separately switched mains power supply or grid 15, as schematically represented by a switch 16, at Certain power cycles provide power to the lighting device 10 .

[0059] The switch 16 may be timed from a central serve...

Abstract

A timing circuit (24) in a lighting device (10) where the power condition of the auxiliary power supply (23) is insufficient to sustain periodic power supply from the main power supply (15) according to a power cycle having a power-on time and a power-off time— - Automatically synchronizing the timing circuit ( 24 ), especially in the case of correct operation of the real-time clock circuit. The power condition of the auxiliary power supply (23) is monitored at each power-up of the power supply cycle. If the determined power condition exceeds the set power threshold, then the instantaneous timing value of the timing circuit (24) is assumed to be correct and the value is stored in the non-volatile memory (29). The timing circuit (24) is synchronized to the stored timing value if the determined power condition, eg due to an extended power outage, results in a hypothetical timing circuit (24) failure.

Description

technical field [0001] The present disclosure relates generally to the field of lighting, and more particularly to a clocked switching lighting device and a method arranged to automatically synchronize a timing circuit for clocking switching of the lighting device after a power interruption. Background technique [0002] In recent years, there has been a migration from simple stand-alone luminaires to lighting systems consisting of multiple luminaires equipped with automatic switching and communication facilities, such as eg timed switching and wireless communication. Such a system of interconnected lighting devices or luminaires provides a wide range of control functions, but is more expensive than a basic luminaire with only a simple on-off function. [0003] In situations where the more basic functionality is sufficient, but an easy adaptation of settings for lighting operations such as timed lighting operation is still required, the TM Or a local point-to-point wireless...
