摘要: The disclosure provides an LED tube lamp, comprising a tube, a terminal adapter circuit, a first rectifying circuit, a filtering circuit, an LED lighting module and an anti-flickering circuit. The tube has a first pin and a second pin for receiving an external driving signal. The terminal adapter circuit has two fuses respectively coupled to the first and second pins. The first rectifying circuit is coupled to the first and second pins for rectifying the external driving signal to generate a rectified signal. The filtering circuit is coupled to the first rectifying circuit for filtering the rectified signal to generate a filtered signal. The LED lighting module is coupled to the filtering circuit and the LED lighting module having a LED module, wherein the LED lighting module is configured to receive the filtered signal and generate a driving signal, and the LED module receives the driving signal and lights. The anti-flickering circuit is coupled between the filtering circuit and the LED lighting module, and is configured such that a current higher than a particular anti-flickering current flows through the anti-flickering circuit when a peak value of the filtered signal is higher than a minimum conduction voltage of the LED module.

摘要: An LED tube lamp comprises a lamp tube, which includes a light transmissive portion, a reinforcing portion and an end cap; and an LED light assembly, which includes an LED light source and an LED light strip. The light transmissive portion is fixedly connected to the reinforcing portion. The reinforcing portion includes a plurality of bracing structures at endpoints. The bracing structure includes a combination of vertical ribs and horizontal ribs. The LED light strip abuts against the bracing structure, which guides the LED light assembly in place. The LED light assembly finds upright support by the reinforcing portion. The LED light source is thermally and electrically connected to the LED light strip. The end cap is attached to an end of the lamp tube. R15 is a ratio of an overall length of the reinforcing portion that shows itself on a circumference of a cross section of the lamp tube to an overall length of the light transmissive portion that shows itself on the circumference of the cross section of the lamp tube. R15 is a constant regardless of where the cross section finds itself on a longitudinal axis of the lamp tube. R15 is from 0.02 to 1.65.
