Abstract: A lighting apparatus includes a light source, a light housing, a light passing cover and a connector module. The light source includes multiple LED modules. The light housing has an internal container and a light opening. The light source is placed inside the internal container. A light of the multiple LED modules escapes from the light opening. At least a portion of light housing is made with a plastic material mixed with an anti-fire material. The anti-fire material increases a melting temperature for deformation of the light housing. The light passing cover covers the light opening. The connector module has a fixing connector and an elastic unit. The fixing connector is fixed to the light passing cover. The elastic unit is used for fastening the light housing to an installation platform when no external force is applied on the elastic unit.

Abstract: An LED tube lamp and an impedance detection method thereof are provided. The LED tube lamp includes a power supply module comprising an impedance detection controller, configured to perform, before the LED tube lamp being lighted up, an impedance detection to determine whether the LED tube lamp is electrically connected to a foreign external impedance in series. When the LED tube lamp is connected to the foreign external impedance in series, the impedance detection controller causes at least two transient variations to an operating current of the LED tube lamp and limits the operating current of the LED tube lamp to not exceed 5 MIU in root-mean-square (RMS), in which a duration of each transient variation does not exceed 1 millisecond when the impedance detection controller performs the impedance detection.

Abstract: An anti-shock night light comprises pins, a night light main body, an anti-shock device, and an elastic resetting member. A first end of the anti-shock device is movably connected to an opening to enable the anti-shock device to move in a length direction of the pins, and a second end of the anti-shock device extends away from the night light main body along the length direction so as to enable a part of the pins, which is exposed out of the night light main body, to be contained within the anti-shock device. When plugging the pins into a socket, the anti-shock device abuts the socket and is retracted toward the night light main body to enable the part of the pins to be exposed and plugged into the socket. When the anti-shock device is retracted toward the night light main body, the elastic resetting member generates an elastic resetting force.

Abstract: An LED tube lamp including an LED module and a power supply module is provided. The LED module is configured to emit light in response to a driving current. The power supply module is electrically connected to the LED module to provide the driving current based on an external driving signal. The power supply module includes a rectifying circuit, a filtering circuit, a driving circuit, a flicker suppression circuit, and an installation detection circuit. The flicker suppression circuit is electrically connected to the LED module, and configured to control a conduction state of a current path passing through the LED module. The installation detection circuit is electrically connected to the flicker suppression circuit, and configured to detect whether a foreign external impedance is electrically connected to the LED tube lamp. When the foreign external impedance is detected, the installation detection circuit disables the flicker suppression circuit to restrict current from flowing through the current path. When the foreign external impedance is not detected, the installation detection circuit enables the flicker suppression circuit to smooth the driving current by controlling the conduction state based on the external driving signal.

Abstract: A power supply module is configured to provide, based on an external driving signal, a driving current for driving an LED tube lamp. The power supply module includes a detection path circuit, configured to establish a detection path which is capable of affecting an electrical signal on a power line of the power supply module when the detection path is turned on, and a driving circuit, electrically connected to the detection path circuit, and configured to produce the driving current based on the external driving signal. When the driving circuit is activated by receiving the external driving signal, the driving circuit enters into a first mode to detect whether a foreign external impedance is electrically connected to the LED tube lamp. When the foreign external impedance is detected, the driving circuit remains in the first mode, and when the foreign external impedance is not detected, the driving circuit enters into a second mode to produce the driving current. The driving circuit is further configured to obtain a dimming message from the electrical signal and adjust the magnitude of the driving current according to the dimming message when in the second mode.
