Lighting for Industrial Greenhouses

How Should Industrial Greenhouse Lighting Be Designed?

Lighting is of great importance for efficient and healthy plant cultivation in industrial greenhouses. Therefore, greenhouse lighting should be designed to provide sufficient light intensity, appropriate color temperature, and uniform distribution to support the photosynthesis process of plants. Since the light spectrum requirements vary at different stages of plant growth, modern greenhouses generally use LED-based systems. This approach ensures energy savings, minimizes heat, and does not negatively affect plant health. Additionally, in industrial greenhouses, lighting must have high durability and long lifespan, and the lighting system must be resistant to humidity, temperature, and water vapor conditions in the greenhouse. As a result, even light distribution enables plants to grow homogeneously throughout the area and improves product quality.

• Growth Areas: These are the most critical regions of industrial greenhouses. Lighting used on shelves and beds where plants are densely concentrated must be designed to provide sufficient light intensity and homogeneous distribution. This ensures that photosynthesis occurs at the maximum level, all plants grow equally, and crop yield increases.
• Germination and Seedling Areas: Special lighting is required in areas where natural light is insufficient for seedlings to root and grow healthily. At this point, LED fixtures that provide low heat emission are generally preferred; this way, young plants are protected from negative temperature effects.
• Harvest and Maturation Areas: The light spectrum is important for the development of the color and quality of the products. LED systems that provide the appropriate spectrum and light intensity are used in areas where plants in the maturation phase are located. This increases product quality while ensuring the maturation process is homogeneous.
• Internal Greenhouse Paths and Maintenance Areas: Since adequate lighting is essential for employee safety and production efficiency, linear LED fixtures or ceiling-mounted spotlights are used in these areas to ensure that employees can move comfortably and perform maintenance operations safely.

What Are the Lighting Products Used in Industrial Greenhouse Lighting?

Industrial greenhouse lighting models are generally categorized based on the size of the area, lighting requirements, and lighting efficiency. Therefore, many industrial greenhouse lighting models are designed with the functional needs of the users in mind. The most frequently preferred industrial greenhouse lighting fixtures are:

• High Bay Lighting Fixtures: Ideal for greenhouses with high ceilings to ensure even light distribution across large areas.

• LED Projectors (Floodlights): Used for wide-angle illumination and high-intensity lighting requirements.

• Floor Lighting Fixtures: Designed to provide targeted light at the plant level or for pathways.

• Weatherproof (Etanj) Fixtures: Essential for humid and harsh environments due to their high IP rating, protecting the inner components from moisture and dust.

How to Choose Lighting Fixtures for Industrial Greenhouses?

When choosing from industrial greenhouse lighting options, attention should be paid to the light spectrum, light intensity, fixture type, and IP protection class. In this context, the points to consider in industrial greenhouse lighting are as follows:

• Light Intensity and Homogeneity: Fixtures that provide sufficient light intensity and homogeneous distribution should be preferred to ensure that plants grow equally in all areas.
• Color Spectrum: Fixtures capable of providing the blue, red, and white light combinations that plants need at different growth stages should be preferred.
• Energy Efficiency: Low-consumption systems, such as LEDs, which provide energy savings during long-term use, should be prioritized.
• Resistance to Water and Humidity: It should be ensured that the fixtures are resistant to the high humidity and temperature conditions of the greenhouse environment.
• Longevity and Durability: It should not be overlooked that the fixtures must be long-lasting and durable to minimize maintenance and replacement costs.
• Ease of Installation and Positioning: Attention should be paid to ensuring that the fixtures are designed to be mounted appropriately in the greenhouse and to direct the light correctly.
• Heat Management: Keeping the heat production of the fixtures to a minimum and ensuring they do not negatively affect the greenhouse temperature should be among the priorities.
