LED straight lamp

Abstract

The invention provides an LED straight lamp. According to the LED straight lamp, the safety function that energizing is achieved only when two end covers of a lamp tube are put in a lamp holder of the lamp simultaneously is achieved, and the effect that installation personnel can avoid the danger of electric shock during installation is ensured. The LED straight lamp comprises the lamp tube, two lamp holders, a rectifying circuit, a filter circuit, an LED driving module and a detection module. The two lamp holders are each provided with a pin used for receiving an outside driving signal and are suitable for being connected with the two ends of the lamp tube correspondingly in a coupling mode. The rectifying circuit is used for rectifying the outside driving signal so as to generate a post-rectifying signal. The filter circuit is used for generating a post-filtering signal. The LED driving module is configured to generate a driving signal to make the LED straight lamp emit light. The detection module is used for determining whether the outside driving signal is stopped from flowing through the LED straight lamp and is provided with a first detection end and a second detection end. When an electric current flowing through the first detection end and the second detection end is higher than or equal to an electric current value, the detection module is switched on. When the electric current flowing through the first detection end and the second detection end is lower than the electric current value, the detection module is switched off.

Description

technical field [0001] The invention relates to the field of lighting appliances, in particular to an LED straight tube lamp. Background technique [0002] LED lighting technology is rapidly developing to replace traditional incandescent and fluorescent lamps. Compared with fluorescent lamps filled with inert gas and mercury, LED straight tube lamps do not need to be filled with mercury. Therefore, in a variety of lighting systems for home or workplace dominated by lighting options such as traditional fluorescent bulbs and tubes, it is no surprise that LED straight tube lights have gradually become a highly anticipated lighting option. The advantages of LED straight tube lights include increased durability and lifespan as well as lower energy consumption. Therefore, after all factors are considered, LED straight tube lights will be a cost-effective lighting option. [0003] Known LED straight tube lamps generally include a lamp tube, a circuit board with a light source in...

AI Technical Summary

Problems solved by technology

[0007] When the LED straight tube lamp is a double-terminal power supply, if one of the two ends of the LED straight tube lamp has been inserted into the lamp holder and the other end has not been inserted into the lamp holder, if the user touches the metal or conductive metal at the end that is not inserted into the lamp holder part, there may be a risk of electric shock
