    • An LED tube lamp (50) includes a tube (100), two end caps (300), a power supply (400), and an LED light strip (200). The tube (100) includes two rear end regions (101), two transition regions, and a main body region (102). The end caps (300) are respectively connected to the rear end regions (101). The power supply (400) is in one or both of the end caps (300). The LED light strip (200) including one or more LED light sources (202) is in the tube (100). The LED light sources (202) are electrically connected to the power supply (400) via the LED light strip (200). The end cap (300) includes a lateral wall (301), an end wall (302), and at least one opening (320) for heat dissipation and/or pressure releasing. The at least one opening (320) penetrates through the end cap (300) with a light sensor (450) inside the end cap (300) collimating with the opening (320).
    • LED管灯(50)包括管(100),两个端盖(300),电源(400)和LED灯条(200)。 管(100)包括两个后端区域(101),两个过渡区域和主体区域(102)。 端盖(300)分别连接至后端区域(101)。 电源(400)在一个或两个端盖(300)中。 包括一个或多个LED光源(202)的LED灯带(200)在管(100)中。 LED光源(202)经由LED灯条(200)电连接到电源(400)。 端盖(300)包括侧壁(301),端壁(302)和用于散热和/或释放压力的至少一个开口(320)。 所述至少一个开口(320)通过与所述开口(320)准直的所述端盖(300)内的光传感器(450)穿透所述端盖(300)。

    • An LED tube lamp (500), in which an installation detection circuit (2520) is configured to receive an external driving signal. The installation detection circuit (2520) is configured to detect during one or more pulse signals whether the LED tube lamp (500) is properly installed on a lamp socket, based on detecting a signal generated from the external driving signal. The installation detection circuit (2520) includes a switch circuit (2580,2680,2780,2880) coupled to the pulse generating circuit (2540,2640,2740,2840), wherein the one or more pulse signals control turning on and off of the switch circuit (2580,2680,2780,2880). The installation detection circuit (2520) is further configured to: when it is detected during one or more pulse signals that the LED tube lamp (500) is not properly installed on the lamp socket, control the switch circuit (2580,2680,2780,2880) to remain in an off state to cause a power loop of the LED tube lamp (500) to be open; and when it is detected during one or more pulse signals that the LED tube lamp (500) is properly installed on the lamp socket, control the switch circuit (2580,2680,2780,2880) to remain in a conducting state to cause the power loop of the LED tube lamp (500) to maintain a conducting state.
    • 其中安装检测电路(2520)被配置为接收外部驱动信号的LED管灯(500)。 安装检测电路(2520)被配置为基于检测到从外部驱动信号产生的信号,在一个或多个脉冲信号期间检测LED管灯(500)是否正确安装在灯插座上。 安装检测电路(2520)包括耦合到脉冲生成电路(2540,2640,2740,2840)的开关电路(2580,2680,2780,2880),其中该一个或多个脉冲信号控制开关电路 开关电路(2580,2680,2780,2880)。 安装检测电路2520还用于当在一个或多个脉冲信号中检测到LED灯管500未正确安装在灯座上时,控制开关电路2580,2680,2780, 2880)保持断开状态以使LED管灯(500)的电源回路断开; 当在一个或多个脉冲信号中检测到LED灯管(500)正确安装在灯座上时,控制开关电路(2580,2680,2780,2880)保持导通状态,使电源 LED灯管(500)的回路保持导通状态。
