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...

Abstract

The invention discloses a flexible starting method of an LED lamp. The method comprises the 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 relationship function. According to the flexible starting method of the LED lamp, the starting time of the LED lamp is prolonged and the light intensity of the LED lamp is increased in a staged mode, so that people in the lighting environment can be provided with enough time for adjusting the light intensity changing, light adaptation can be avoided and people's eyesight can be protected.

Description

technical field [0001] The invention relates to the field of dimming control of lamps, in particular to a flexible starting method for LED lamps. Background technique [0002] LED is a kind of diode with good switching characteristics. As a lighting fixture, LED also has many excellent characteristics such as small size, low power consumption, long service life, high brightness, low heat, environmental protection, and strong controllability. The industrialization of lighting has increasingly attracted widespread attention from all over the world. Through the implementation of the "National Semiconductor Lighting Project" and the introduction of a series of policies and measures to promote the development of the green lighting industry in China, coupled with the promotion of the "Ten Cities and Ten Thousand Lights" project , so that the application scale of LED gradually expands and has a broad prospect. [0003] At present, in the dimming control technology of LED lamps, th...
