- External differences
LED, also known as light-emitting diode, is a chip composed of P-type and N-type semiconductors. There is a transition layer between the P-type and N-type semiconductors, called the P-N junction. When the current flows from the LED anode to the cathode, the semiconductor crystal emits light of different colors from purple to red, and the strength of the light is related to the current.
The study of plant lamps as supplementary lighting for plant photosynthesis traditional artificial light sources generate too much heat, such as using LED supplementary lighting and hydroponic systems, where air can be recycled and excess heat and water can be removed.
- Different uses
Normal lamps can replace spiral incandescent lamps or energy-saving bulbs, ranging from 5-40 watts, low-power incandescent lamps, to 60 watts (only about 7 watts of electricity are needed).
Plant lamps can help shorten the growth cycle of plants, as the light source of this lamp is mainly composed of red and blue light sources, using plant sensitive light bands. The red light wavelength uses 620-630nm and 640-660nm, while the blue light wavelength uses 450-460nm and 460-470nm.
- Differences in wavelength of luminescent spectra
The wavelength types are diverse and perfectly match the spectral range of plant photosynthesis and light morphology; The half width of the spectral wave is narrow, which can be combined as needed to obtain pure monochromatic light and composite spectra; Can concentrate specific wavelengths of light to evenly illuminate crops; Not only can it regulate crop flowering and fruiting.
