In modern commercial freezer lighting, most commercial freezer luminaires on the market are equipped with lenses. This is because lenses have the ability to focus light, enabling the precise projection of light onto product surfaces, effectively avoiding the generation of ineffective light, and thus enhancing display effects and energy utilization efficiency. Ошондой, how can we determine the optimal installation position for luminaires, and how should products be arranged to achieve uniform illumination? Here are the detailed answers.
Key Points for Installation of Pillar Lights and Product Placement
For pull-door freezers, we generally recommend using a combination of pillar lights and ceiling lights. As a matter of common sense, the closer to the light source, the brighter the area. But does the same apply to luminaires with polarizing technology? We conducted tests to find out.

Key Points for Installation of Horizontal Luminaires and Product Placement
Horizontal luminaires are used in air curtain freezers. For horizontal freezer lights, we strongly recommend using frosted lampshades. This is because transparent lampshades tend to produce glaring light, клиент-влаклан эҥгекым ыштыше’ visual experience, while frosted lampshades can diffuse light more softly and uniformly, creating a comfortable shopping environment.
When installing horizontal luminaires, what is the relationship between the installation position of the luminaires and the placement of products? Professional tests have revealed that when products are placed 50mm away from the edge of the shelves, the lumen value reaches its peak. This means that at this position, products can receive the most abundant light, and the lighting effect for an entire row of products is very uniform, without local over-brightness or under-brightness. This can fully display the details and features of the products, клиент-влакым тарватымаш’ шекланен.

Case Study about Freezer Lighting Upgrade and Renovation Project

The pain points were crystal clear:
The T8 LED tubes originally used by the customer had significant limitations. When it came to product display, the lighting could only effectively illuminate the products if they were placed snugly against the inner side of the shelves. Once the products were positioned at the outermost edge of the shelves, they would be plunged into darkness, severely impacting the product display effect and the customers’ шопинг опыт.

Taking into account the customer’s need to save costs, we replaced the T8 fluorescent tubes with SPU series luminaires.

This helps the customer save on operational costs, achieving a win-win situation in terms of economic and environmental benefits.

SPU Series Luminaire User Guide
When using our SPU series luminaires, there are corresponding optimal installation and placement plans based on different types of luminaires. If you install shelf lights, even when products are placed at the outermost edge of the shelves, they can be fully illuminated without worrying about lighting dead zones. For pillar lights, as previously mentioned, placing products 100mm away from the lights will provide uniform and bright illumination, allowing products to be presented in their best light to customers.
