Abstract
A light emitting diode (LED) device including a transparent substrate, a plurality of LED chips, a circuit, and a transparent encapsulant is provided. The LED chips are fixed on the transparent substrate, and utilized for radiating at least a light beam. The circuit is disposed on the transparent substrate and electrically connected to the LED chips. The transparent encapsulant is utilized for packaging the LED chips. The light beam of the LED chips can propagate from two opposite sides of the transparent substrate. Blue LED chips and the circuit of the transparent substrate can be directly soldered, and the phosphors are arranged to convert the wavelength of blue light, so a dual-side white light emitting device can therefore be provided.
