Actuellement, there are two main types of vertical refrigerators on the market: Refrigerated multi-deck cabinet open or closed. Refrigerated multi-deck cabinet closed are primarily used to display products that require high refrigeration temperatures, such as beverages, while refrigerated multi-deck cabinet open are mainly used to display frozen foods, légumes, and fruits, which are convenient for customers to grab and go. Although their structures differ, they share similar application scenarios and a common lighting design solution: canopy and shelf lighting.
The types of lighting in retail stores or supermarkets.
As a top LED factory in China with 13 years of experience in LED R&D and manufacturing in refrigerated display lighting, Laidishine’s product design focuses on addressing customers’ needs for refrigerated display case lighting. The primary challenge facing vertical refrigerators is uniform illumination of the displayed merchandise. This led to the development of the canopy light. This product not only illuminates the top shelf, but also the entire front of the cabinet. Laidishine uses high-CRI LEDs, and their unique arrangement ensures uniform light distribution across the surface. The IP65-rated LED strips for humid environments can withstand temperatures ranging from -30°C to +30°C. The high-quality aluminum profile inside the cabinet effectively dissipates heat and maintains the internal temperature.
Cependant, illuminating only the cabinet surface can create dark areas deep within the shelves. To address this, separate luminaires are installed on each shelf. Le SPU-H et SPU-HB illuminate the surface while also penetrating deep into the shelves to illuminate these dark areas. Aussi, the products all use waterproof refrigerator LED strips, which can reach an IP65 rating. Their high CRI, lens design, and wide beam angle ensure excellent illumination deep within the commercial shelf lighting systems. The lamps are compact and lightweight, making them easy to install. They can be attached directly to steel shelves using strong magnets, but other materials can also be secured with screws. Both products are UL and CE certified, meeting the requirements of the import and export corporation.
The main difference between the SPU-H et SPU-HB is that the SPU-H has a single-ended cable outlet and a milky white cover to reduce glare, making it suitable for customers seeking a softer lighting effect and a smaller number of shelves. Le SPU-HB has a double-ended cable outlet and often features a transparent cover, making it suitable for island cabinet lighting. When used as a shelf light, the double-ended cable outlet allows for series connection of the lamps, reducing the need for connecting cables and making it suitable for customers with a large number of shelves. Of course, for customers with multiple shelves who desire a softer lighting effect, Laidishine specially developed a wiring harness for the series connection of shelf lights is available. We provide a main bus followed by 3, 4, 5, ou 6 branch lines.
Vertical Refrigerators Lighting Solution – The Use of Vertical Lighting
The aforementioned products can fully meet the lighting needs of refrigerated multi-deck cabinets, open or closed. Cependant, for refrigerated multi-deck cabinets-closed, due to the different internal structure of the cabinet and the obstruction of the glass door, a dark spot is created at the door frame of the glass door. The illumination from the canopy light and shelf light is insufficient to solve this problem. Donc, vertical lights are installed in the door frame to cover the shelf surface. The vertical lights, through the support of lenses, cross-radiate light from the left and right sides of the freezer, ensuring uniform light distribution across the entire surface, thus eliminating dark areas and shadows.
How to distinguish during installation – The principle of the special lens
To increase the beam angle, reduce the glare of LED beads, improve light utilization, optimize lighting, and provide more uniform light, Laidishine has incorporated a lens design into its products. This control of the light propagation path is achieved through refraction, reflection, and total internal reflection. Donc, when installing products with lenses, pay attention to the installation direction. When installing horizontally, the person faces the cabinet, with the lens facing downward, allowing light to reach both the shelves and the surface. When installing vertically, the person faces the cabinet, with the lens facing the cabinet door, as shown in the example image. (Please note “Gauche” ou “Droite” is based on “a person facing the cabinet.”)
