Linear solid-state lighting with broad viewing angle

A linear light-emitting diode (LED) tube lamp, comprising:

• a housing having two ends and a curved surface on a top side thereof between the two ends;
• a light-emitting diode printed circuit board (LED PCB) which is curved to closely fit the curved surface and is fixed on the curved surface, the LED PCB having a plurality of LEDs fixed thereon;
• an LED driver that powers the plurality of LEDs on the LED PCB, wherein the LED driver has two inputs and is fixed inside the housing below the curved surface;
• and
• two lamp bases respectively connected to the two ends of the housing, each lamp base having an end cover and a lamp base PCB assembly comprising a bi-pin with two pins protruding outwards through the end cover, a lamp base PCB, and a shock protection switch mounted on the lamp base PCB, wherein:
• when the shock protection switch is off, the bi-pin is not electrically connected with the LED driver;
• when the bi-pin is inserted into a lamp socket, the shock protection switch is actuated to electrically connect the bi-pin with one of the inputs of the LED driver.
