Abstract
The present disclosure relates to techniques for providing a liquid metal alloy in a light-emitting diode device that can both heal cracks formed in solder joints on the light-emitting diode (LED) device as well as improve thermal energy dissipation from the LED chips to improve the performance, reduce wear, and prolong the life of the LED chips. In an embodiment, a light-emitting diode device can include a liquid metal alloy containing gallium next to a solder joint, and when one or more cracks form, the liquid metal alloy can enter the cracks and solidify, healing the cracks. The liquid metal alloy can also be placed adjacent to, and in contact with the LED chip to transfer energy away from the LED chips.
