Abstract
A slim linear LED lighting device is provided, including: a printed circuit board on which a connecting circuit is provided, at least one power input component, and a plurality of LED Bars. The LED Bar is formed by a plurality of the same kind of LED chips, and has a slim strip-shaped condensing lens structure integrally formed in the LED Bar packaging process by molding process to control the beam angle of the LED Bar and therefore the light distribution of the slim linear LED lighting device. The LED Bar's condensing lens has a small cross-sectional dimension; therefore the effective utilization factor of the light is improved as the slim linear LED lighting device is applied to a linear automotive lamp designed with a thin light blade structure.
