The LED module is the core component of a display system. It consists of an LED circuit board enclosed in a housing, with LED lamp beads arranged according to specific patterns and often treated for water resistance. As the LED display industry continues to evolve and application requirements become more demanding, the importance of LED modules has only increased.
Today, we’ll take a closer look at the seven key parameters that define an LED module:
1. **LED Module Color**
This is the most basic characteristic of an LED module. Different colors are used in various applications. The color types can be divided into two main categories: monochrome and full-color single-point control. Monochrome modules emit a single, unchangeable color and operate when connected to a power source. Full-color single-point modules allow individual color control per unit, enabling image and video displays when multiple modules are combined. With the addition of a control system, full-color modules can produce dynamic visual effects.
2. **LED Module Brightness**
Brightness is one of the most important factors people consider when evaluating LED modules. It refers to the light intensity and transparency of the LEDs, typically measured as the sum of brightness levels across each module. High brightness ensures visibility even in bright environments, making it crucial for outdoor and large-scale displays.
3. **LED Module Viewing Angle**
The viewing angle of an LED module without a lens depends largely on the LED lamp beads used. Different lamp beads have varying angles, and manufacturers usually specify this angle as part of the module’s performance. A wider viewing angle allows for better visibility from different positions, enhancing the overall user experience.
4. **LED Module Operating Temperature**
The normal operating temperature range for an LED module is generally between -18°C and 58°C. If the environment exceeds these limits, additional measures such as air conditioning or fans may be required to ensure stable operation and prevent damage.
5. **LED Module Voltage**
Voltage is a critical parameter for LED modules. Most commonly, 12V low-voltage modules are used. When connecting power and control systems, it’s essential to verify the voltage value before powering up to avoid damaging the module.
6. **LED Module Size**
This refers to the physical dimensions—length, width, and height. In large-scale projects, the maximum number of modules that can be connected in series is also an important consideration. This is influenced by the length of the connection cables and may require customization based on project needs.
7. **LED Module Waterproof Rating**
For outdoor use, the waterproof rating is a key factor in ensuring long-term reliability. An IP65 rating is typically recommended for open-air installations, as it provides protection against dust and water spray, making the module suitable for harsh weather conditions.
By understanding these seven parameters, you can make more informed decisions when selecting and using LED modules for your display applications.
