LED lamp using blue and cyan LEDs and a phosphor

Many thousands of micro-LEDs (e.g., 25 microns per side) are deposited on a substrate. Some of the LEDs are formed to emit a peak wavelength of 450 nm (blue), and some are formed to emit a peak wavelength of 490 nm (cyan). A YAG (yellow) phosphor is then deposited on the LEDs, or a remote YAG layer is used. YAG phosphor is most efficiently excited at 450 nm and has a very weak emission at 490 nm. The two types of LEDs are GaN based and can be driven at the same current. The ratio of the two types of LEDs is controlled to achieve the desired overall color emission of the LED lamp. The blue LEDs optimally excite the YAG phosphor to produce white light having blue and yellow components, and the cyan LEDs broaden the emission spectrum to increase the CRI of the lamp while improving luminous efficiency. Other embodiments are described.
