Claim Text:
1. A light emitting diode (LED) device, comprising: a transparent substrate comprising a first surface and a second surface opposite to the first surface, wherein the first surface has a first reflection zone, a second reflection zone and a transparent zone outside of the first reflection zone and the second reflection zone thereon; a first and a second reflection layers disposed on the first and the second reflection zones respectively; a first and a second LED chips electrically connected with each other and disposed on the first and the second reflection layers respectively, wherein an orthographic projection of the first LED chip onto the transparent substrate is located within the first reflection zone and an orthographic projection of the second LED chip onto the transparent substrate is located within the second reflection zone; a positive electrode and a negative electrode disposed on an end of the transparent substrate and electrically connected to the first and the second LED chips respectively; and a wavelength-converting layer at least covering the first and the second reflection layers and the first and the second LED chips, wherein the first and the second reflection layers respectively reflect a portion of light beams emitted from the first and the second LED chips to the wavelength-converting layer.
