摘要： A linear light-emitting diode (LED)-based solid-state lamp comprising an LED driving circuit, LED arrays, at least one pair of electrical contacts, and a controller, is used to replace a fluorescent tube or a conventional LED tube lamp in an existing lamp fixture. The controller and the at least one pair of electrical contacts are configured to perform galvanic isolation between the controller and the LED driving circuit connecting with LED arrays. Thus an overall through-lamp electric shock current can be limited only from the controller, eliminating a substantial electric shock current flow through the LED driving circuit and subsequently the LED arrays. The scheme can effectively reduce a risk of electric shock and an internal fire hazard to users during relamping or maintenance.

摘要： An illumination device includes a laser element, a fluorescent material, a light projection lens, a laser light reflector, a detection element, and a control unit connected to the detection element. The fluorescent material is disposed in a direction of propagation of laser light from the laser element, and converts the laser light into illumination light. The light projection lens and the laser light reflector are disposed in a direction of propagation of the illumination light from the fluorescent material. The detection element can detect the laser light reflected on the laser light reflector and external light. The control unit calculates a comparison value by comparing the amount detected by the detection element when the laser element is emitting the laser light and the amount detected by the detection element when the laser element is not emitting the laser light. When this comparison value becomes larger than the first threshold, the control unit stops or attenuates the laser light from the laser element.

摘要： An LED tube lamp is disclosed. The LED tube lamp includes an LED module for emitting light, the LED module comprising an LED unit comprising an LED; a rectifying circuit for rectifying an external driving signal to produce a rectified signal; and a mode determination circuit configured to detect a state of a property of the rectified signal, for selectively determining on performing a first mode or a second mode of lighting according to the state of the property of the rectified signal; wherein when the LED tube lamp performs the first mode of lighting, the mode determination circuit allows continual current to flow through the LED unit until the external driving signal is disconnected from the LED tube lamp; and when the LED tube lamp performs the second mode of lighting, the mode determination circuit regulates the continuity of current to flow through the LED unit.

摘要： A linear light-emitting diode (LED) tube lamp using a six-diode combination and a ballast compatible and AC mains operable (BA) LED driving circuit operate normally with AC mains in a single end and with an electronic ballast in double ends. The BA LED driving circuit configured to operate in a wide range of input voltages and frequencies, especially for various high voltages and high frequencies associated with various electronic ballasts to provide a regulated power and a current from either electronic ballast or AC mains. With a cycle-by-cycle current control and power switching at a constant on-time and varied off-time, an over-rated surge current is limited, preventing occasional fire hazards occurred in the ballast. An additional frequency sensitive device is used to prevent a possible electric shock from occurring for both configurations during initial installation and re-lamping, thus no shock protection switches needed.
