Grow Lighting Source

I. Characteristics of Grow Lighting Source

1.1. Application Advantages & Spectral Characteristics

The Sunlight Plant Growth Lighting Source produces continuous full-spectrum white light from 280nm to 2500nm, with visible light accounting for 85% and infrared and ultraviolet light together making up 15%. Its color temperature is as stable as sunlight at 10 a.m. With an exceptionally long lifespan, it requires no bulb replacement for 10 years, maintaining over 80% luminous efficiency. Its modular design enables more flexible and simpler optical configuration.

With a well-balanced spectral distribution, the Sunlight Plant Growth Lighting Source provides the essential light quality and energy for healthy plant growth, helping to enhance the vitality, quality, and yield of plants and animals. Invisible light (infrared and ultraviolet) plays a key role in plant development and healthy growth, significantly increasing the content of antioxidants (such as flavonoids and vitamin C) in fruits, promoting the accumulation of sugars, anthocyanins, phenolic acids, and aromatic compounds. This improves flavor and taste while enhancing broad-spectrum resistance to pests, diseases, drought, and cold, achieving higher yields, better quality, and more natural cultivation results.

As a result, it is not only energy-efficient but also delivers planting outcomes closer to natural sunlight: plants grow vigorously, with rich nutritional content and authentic flavor, while also reducing pest occurrence. The visible light portion of the Sunlight Plant Growth Lighting Source has a red/green/blue ratio of 41/32/27, closely matching that of natural sunlight, as shown in the table below:

1.2 Research Results on Application of Sunlight Plant Growth Lighting Source

The Sunlight Plant Growth Lighting Source contains approximately 14% infrared light and 1% ultraviolet light, primarily UVA and UVB, providing the essential light quality and energy required for biological growth.

A study conducted by Wageningen University & Research in the Netherlands compared different light sources for plant growth. The results showed that this light source not only saves energy and increases yield, but also enhances authentic flavor and reduces pest incidence.

Four light sources of similar power were used to study their effects on five plant species. Comparisons were made across multiple dimensions including color, growth rate, flowering, fruiting, flavor, and nutritional content. The results showed that LEP was not only energy-efficient but also delivered the best growth performance—shorter growth cycles, higher nutritional value, and more authentic flavor.

In the early stages of plant development, plants grown under the Sunlight Plant Growth Lighting Source (LEP) exhibited more compact internodes, grew more vigorously, faster, and produced more biomass compared to those grown under HPS. Experimental results showed that a 230W LEP significantly outperformed a 600W HPS in terms of nutritional performance, flowering, and fruiting. Tomatoes grown under LEP were not only visually appealing with uniform size, but also had exceptionally rich flavor. Additionally, no spider mite infestation was detected on the plants.

1.3 Application Areas

The Sunlight Plant Growth Lighting Source is suitable for greenhouse cultivation, plant factories, seedling nurseries, agricultural research, hydroponics, and animal farming—ideal for indoor environments or regions with limited winter sunlight. It can be used for plant growth lighting as well as supplemental lighting where natural light is insufficient.

2.2 Environmental requirements

A) Work Environment

Temperature -25℃ to +45℃, humidity 5%-95%.

B) Storage environment temperature

Temperature -40℃ to +80℃, humidity 5%-95%.

2.3. Heat dissipation requirements

A) Power supply cooling

If the power supply is external, the power supply shell itself can meet the heat dissipation requirements. If the power supply is built-in, the heat dissipation must meet the requirement that the temperature rise is less than 35°C under a 25W heat source.

B) Power amplifier heat dissipation

The power amplifier (microwave solid-state source) must meet the requirement that the temperature rise is less than 35°C under an 80W heat source.

C) System cooling

When the ambient temperature is 30°C, the shell temperature of the entire Sunlight simulation source system must be kept below 70°C to meet safety regulations.
