照明

illuminate
💡 照 shine + 明 bright = lighting; 明 itself = 日 sun + 月 moon
照明 stacks 照 (to shine, light cast on something) with 明 (bright), so the pair means lighting or illumination. The 明 half is sun plus moon set side by side, the two brightest things, reinforcing the brightness sense.
照 — 昭 (bright) phonetic + 灬 (fire radical)
照 is a semantic-phonetic compound. The bottom 灬 is a variant of 火 'fire', giving the meaning of light or illumination, while 昭 'bright' on top supplies the sound 'zhào' and reinforces the brightness sense. It originally meant to shine light on something, later extending to 'reflect', 'photograph', and 'according to'.
