Abstract

The invention provides an anti-stroboscopic lamp with a constant luminous flux compensation function, which is characterized by comprising a current detection unit configured with current for detecting a power supply module, a current setting unit connected with the current detection unit through a circuit and capable of setting target current of the power supply module, a control signal unit respectively connected with the current detection unit and the current setting unit through circuits and capable of obtaining and comparing current values of the current detection unit and the current setting unit and storing a current control flow, and an adjustment control unit connected with the compensation unit in the power supply module and capable of controlling the current control amplitude ofthe compensation unit so as to compensate the luminous flux of the lamp and prevent stroboflash. The invention further provides a luminous flux compensation control method of the anti-stroboscopic lamp.

Description

technical field [0001] The invention relates to the field of output luminous flux control of lamps, in particular to an anti-flicker lamp with constant luminous flux compensation function and a luminous flux compensation control method for the anti-stroboscopic lamp. Background technique [0002] As we all know, when the power supply device provides power for electrical appliances, its current will change due to the influence of the mains voltage change, and the lamps will flicker or change temperature due to electromagnetic interference. Therefore, it is necessary to control the current through the compensation unit. At present, all kinds of LED lamps are facing various problems of dimming and color adjustment. Dimming has always been a very challenging task. Dimming is very important in many luminaire applications because dimming technology allows customers to set the desired brightness according to actual needs, and it can also save a lot on electricity bills. But now th...
