Embodiment Construction
[0016] A method for flexible start-up of an LED lamp, comprising an LED lamp and a dimmer of the LED lamp. When the LED lamp is started, the dimmer controls the brightness of the LED lamp to change according to a time-related function. The mathematical expression of the brightness-time function (1) is:
[0017] (1)
[0018] The meanings of the variables in the mathematical expression (1) are:
[0019] L 1 (t) represents the normalized brightness, the value type is a positive real number, and the value range is (0,1], dimensionless;
[0020] t max Indicates the maximum value of time, the value type is a positive real number, the value range is (0,5], and the unit is s;
[0021] t represents time, the value type is a positive real number, and the value range is (0, t max ], the unit is s.
[0022] The curve of the mathematical expression (1) is as figure 1 shown.
[0023] When using a dimmer to adjust the start-up brightness of LED lamps, first set the time i...
