Designing and Installing LED Backlighting for Lightboxes

Illuminating lightboxes effectively is key to enhancing their visual appeal and functionality. While Hi-Line predominantly recommends and specializes in edge lighting for lightboxes — a method where LED modules are installed on just two sides of the lightbox, offering a sleek and efficient lighting solution — we also recognize the significance of backlighting in certain applications. Backlighting, where LED modules are placed directly behind the display surface, provides a different kind of efficiency, brightness, and uniformity that is preferable in specific scenarios. This case study will specifically focus on the backlighting method, utilizing our HL-S2004 modules, to demonstrate an optimal lighting solution for situations where backlighting is advantageous. It's important to note that each method has its benefits and is selected based on the unique requirements of each project.

Lightbox Specifications (example):

Typical Dimensions: 1 meter width x 2.5 meters height

Depth: 150 millimetres

Module Specifications (Example: HL-S2004):

Beam Angle: 170° for wide coverage

Dimensions: 180mm (length) x 26mm (width) x 8.4mm (height)

Luminous Flux: 500 lumens per module, ensuring bright output

Voltage: DC12V, suitable for most applications

Power: 4W per module, offering a balance of brightness and energy efficiency

IP Rating: IP65, making them ideal for both indoor and outdoor use

Maximum Series Connection: 12 modules, allowing for flexibility in installation

Design Considerations:

Height Coverage: Determine the number of modules required to cover the height of the lightbox. For example, in a 2.5-meter tall lightbox, one might use 8 modules from a chain of 12, adjusting as necessary.

Width Coverage: Plan the number of columns needed to cover the width of the lightbox, considering the module's dimensions and desired spacing. For instance, installing 4 columns with a 12cm spacing between each can effectively cover a 1-meter width.

Installation and Efficiency:

LED modules like the HL-S2004 are sold in sets (e.g., 24 modules per set), often comprising chains of 12 modules each. This allows for convenient installation and efficient usage.

Surplus modules from a set can be efficiently utilized in future projects, minimizing waste and maximizing value.

Cost Analysis:

When purchasing LED modules, consider the total cost and how it breaks down per module. Calculate the proportional cost for the number of modules used in a specific lightbox project.

Account for the value of any surplus modules, which can be beneficial for future installations.

Installation Tips:

Adhere to the maximum series connection of modules to ensure uniform brightness.

Connect additional chains in parallel if more modules are needed, while maintaining the series limit.

Choose an appropriate LED driver that matches the power requirements of the total number of modules used.

Conclusion:

Designing and installing LED backlighting in lightboxes requires careful planning in terms of module selection, spacing, and electrical considerations. By following the guidelines outlined in this case study, one can achieve a well-lit, efficient, and visually appealing lightbox display.
