“…PCB assembly was then performed to fabricate the PCB evaluation board shown in Figure 13. The PCB evaluation board had a compact size of 50 × 50 mm 2 . From Figure 12, it is noted that there was still space between the GaN LED and the GaN FET due to machine constraints, which can be reduced in the future.…”

“…LED bulbs are also much more energy efficient and have a longer lifespan compared to other types of light bulbs [1]. Other than providing illumination with great energy savings, LEDs can play a significant role in smart cities, such as in the implementation of visible light communication (VLC) technology, where digital lighting is enhanced to complement radio frequency (RF) transmissions [2][3][4][5][6]. To enable the next generation of smart lighting, it is therefore crucial to explore methods that improve the energy efficiency of current integrated LED technology to reduce such costs.…”

Light-emitting diodes (LEDs) are solid-state devices that are highly energy efficient, fast switching, have a small form factor, and can emit a specific wavelength of light. The ability to precisely control the wavelength of light emitted with the fabrication process enables LEDs to not only provide illumination, but also find applications in biology and life science research. To enable the new generation of LED devices, methods to improve the energy efficiency for possible battery operation and integration level for miniaturized lighting devices should be explored. This paper presents the first case of the heterogeneous integration of gallium nitride (GaN) power devices, both GaN LED and GaN transistor, with bipolar CMOS DMOS (BCD) circuits that can achieve this. To validate this concept, an LED driver was designed, implemented and verified experimentally. It features an output electrical power of 1.36 W and compact size of 2.4 × 4.4 mm2. The designed fully integrated LED lighting device emits visible light at a wavelength of approximately 454 nm and can therefore be adopted for biology research and life science applications.
