LED植物生长灯是节能型人工照明设备,旨在发射驱动植物光合作用的特定光谱。现代全光谱LED取代或补充室内和垂直农业系统中的阳光,提供植物最有效利用的目标波长——主要是红色和蓝色。
关键事实
- Full-spectrum LEDs cover 380–750 nm, mimicking natural sunlight
- Red light (630–660 nm) drives flowering and fruiting; blue (430–460 nm) drives vegetative growth
- Up to 70% more energy-efficient than HPS or fluorescent grow lights
- Produce minimal heat compared to HID lights, reducing cooling costs
- Lifespan of 50,000+ hours — significantly longer than HPS bulbs
- Key metric is PPFD (µmol/m²/s) — the amount of usable light reaching the plant canopy
