Abstract

The present application discloses linear solid state lighting with reliable shock current control without fire hazard, wherein a linear light emitting diode (LED) tube light comprises: a housing, two lamp caps at both ends of the housing, a full wave rectifier, an LED driver Circuit, LED array, two displacement sensors, and two pairs of electrical contacts controlled by the two displacement sensors, the lamp is used to replace fluorescent tubes or traditional LED tube lamps. The two displacement sensors and the two pairs of electrical contacts are configured to perform position sensing for the risk of electric shock, respectively. The two pairs of electrical contacts work by using a low direct current (DC) voltage provided by the power maintenance device. When both lamp caps are inserted into the two sockets, the two pairs of electrical contacts are driven to make electrical connections from the power maintenance device to the low voltage input of the LED driver circuit and to power the LED driver circuit. The use of low DC voltage when used with ballasts eliminates arcing that can cause internal fires, and when used with AC mains prevents large amounts of shock current from passing through the human body to the ground and causing electrocution.

Description

technical field [0001] The present invention relates to linear light emitting diode (LED) lamps, and more particularly to linear LED lamps with reliable low voltage control for electric shock hazards, configured to eliminate arcing that can cause internal fires when used with ballasts and when used in conjunction with AC ( When used together with AC) mains, it prevents electric shock current from reaching the ground through the human body. Background technique [0002] Solid-state lighting derived from semiconductor light-emitting diodes (LEDs) has thus far received a great deal of attention in general lighting applications. LED-based solid-state lighting will soon become the norm for general lighting due to its potential to be more energy-efficient, more environmentally friendly (without the use of hazardous materials), more efficient, smaller and have a much longer lifespan than traditional incandescent bulbs and fluorescent tubes. mainstream. With the development of LED...
