According to foreign media reports, Toyota Synthetic Co., Ltd. (Toyoda Gosei Co., Ltd.) developed its first headlight light-emitting diode (LED). According to its internal test evaluation, the brightness and low energy consumption of such LEDs have reached world-class levels.
Toyota Synthetic uses LED blue crystal growth technology, which has been developed for many years to enhance the crystal structure of gallium nitride (GaN) in LED light sources.
In addition, Toyota Synthetic also uses flip-chip technology, which has good heat dissipation. These headlamp LEDs have a brightness of up to 2,300 lm and can be used in bi-functional systems to produce low beam and high beam with a single source.
The headlights using such LEDs help to reduce the energy consumption of electric vehicles and fuel cell vehicles. It is expected to be widely used in the future and is an environmentally friendly product. To meet the needs of users, Toyota Synthetic will continue to develop LED light sources for various headlights.
With flip chip technology, the LED chip will be directly connected to the substrate, eliminating the need for wiring. Compared to wire bonding, it helps to improve its heat dissipation because wire bonding requires wires to connect the LED chips to the circuit.
