    • A pulse width (PW) digitizer comprises a current pump, a capacitor, a quantizer, a feedback controller, and a digital filter. The current pump provides a current signal in response to a PW signal. The capacitor obtains a voltage signal in response to the current signal. The quantizer obtains a digital signal in response to the voltage signal. The feedback controller determines a feedback PW signal in response to the digital signal. The feedback PW signal is fed back to the current pump for controlling the current signal converging to a specific value and controlling the digital signal switching between a first code and a second code. The digital filter counts times that the digital signal indicating the first code/the second code and accordingly obtains the PW of the PW signal.

    • A light guide lens includes a lens body having a light incidence surface and a light emission surface, a plurality of refraction structures formed on the light incidence surface, and a plurality of reflection structures formed on the light emission surface. The refraction structures send incoming light rays to the light emission surface by refraction. Each of the refraction structures turns incoming light rays coming in all directions into refracted parallel light rays. The refracted parallel light rays arriving from the refraction structures reflect off the corresponding reflection structures and then laterally exit the lens body. The refracted parallel light rays arriving from each of the refraction structures travel to a corresponding one of the reflection structures, such that eventually the incoming light rays exit laterally. The present invention further provides a light emitting diode package structure having the light guide lens.
    • 导光透镜包括具有光入射面和发光面的透镜体,形成在光入射面上的多个折射结构以及形成在发光面上的多个反射结构。 折射结构通过折射将入射光线发射到光发射表面。 每个折射结构将来自各个方向的入射光线转换成折射平行光线。 从折射结构到达的折射平行光线反射出相应的反射结构,然后横向离开透镜体。 从每个折射结构到达的折射平行光线行进到相应的一个反射结构,使得最终入射光线横向离开。 本发明还提供一种具有导光透镜的发光二极管封装结构。
