Publication number: 20170038009Abstract: An AC LED lamp structure includes a light-emitting module and a protection module. The light-emitting module includes a circuit substrate positioned on a carrier body and a light-emitting unit disposed on the circuit substrate. The protection module includes a transparent element disposed under the light-emitting unit and separated from the light-emitting unit and a plurality of connection components connected between the transparent element and the carrier body for positioning the transparent element under the circuit substrate by a predetermined distance. Therefore, the flammability class of the AC LED lamp structure is increased by using the transparent element. The predetermined distance from the transparent element to the circuit substrate is smaller than a finger of a user in order to prevent the finger of the user from touching the circuit substrate through a gap between the transparent element and the circuit substrate, and avoid electric shock.Type: ApplicationFiled: October 7, 2015Publication date: February 9, 2017Inventors: CHIA-TIN CHUNG, SHEN-TA YANG, SHIOU LIANG YEH
