Abstract:
1. An LED (Light-Emitting Diode) light bar, comprising a heat dissipation strip, a printed circuit board (PCB) mounted on the heat dissipation strip, LED chips mounted on the heat dissipation strip and electrically connected to the PCB, and a thermal interface material layer arranged between the LED chips and the heat dissipation strip; wherein the heat dissipation strip comprises an inverted T-shape that comprises a base and a raised portion that is an elongate continuous portion provided on the base and two recesses on opposite sides of the raised portion, the PCB comprising two split pieces respectively received in the recesses, the LED chips being distributed along the raised portion and spaced from each other, each of the LED chips being arranged astride the raised portion to electrically engage the two PCB pieces, the thermal interface material layer being sandwiched between a bottom of each of the LED chips and the raised portion of the T-shape of the heat dissipation strip.
