Lamp unit with a plurality of light source and toggle remote control method for selecting a drive setting therefor
First Claim
1. A lamp unit comprising:
- a plurality of light sources;
a control unit adapted to control a sequence of drive settings for said plurality of light sources based on a switching signal supplied to the lamp unit;
wherein said control unit is arranged such that;
if the switching signal is deactivated and within a first predetermined time interval is subsequently reactivated, a subsequent drive setting of said light sources is employed, or elseif the switching signal is deactivated and after a second predetermined time interval, is subsequently reactivated, a previous drive setting of said light sources is employed, or elseif the switching signal is deactivated and within a predetermined first intermediate time interval, arranged between the end of said first predetermined time interval and the end of said second predetermined time interval, is subsequently reactivated, a predetermined drive setting is employed.

Abstract
The present invention relates to a lamp unit (100) in which a plurality of light sources (120a-e) are controlled by means of a control unit (110) which is adapted to control a sequence of drive settings (Sa-e) for the plurality of light sources based on a switching signal (Sin) supplied to the lamp unit. The control unit is arranged such that depending on the elapsed time between deactivation of and subsequent reactivation of the switching signal, the control unit sets the current drive settings in a predetermined manner. Within a first predetermined time interval a subsequent drive setting of the light sources is employed, after a second predetermined time interval a previous drive setting of the light sources is employed, and within an intermediate time interval, arranged between the end of the first predetermined time interval and the end of the second predetermined time interval a predetermined drive setting is employed.

14. A method for controlling a plurality of light sources based on a switching signal comprising:
-
providing a sequence of drive settings for said light sources from which sequence a present drive setting for said light sources is set; detecting a deactivation of said switching signal; measuring the elapsed time between said deactivation and a subsequent activation of said switching signal; and if said elapsed time is less than a first predetermined time interval; setting a subsequent drive setting as present drive setting;
orif said elapsed time is more than a second predetermined time interval; keeping said present drive setting;
orif said elapsed time is within a first intermediate time interval arranged between the end of said first predetermined time interval and the end of said second predetermined time interval; setting said present drive setting to a predetermined drive setting. - View Dependent Claims (15)
