A sequential LED module is a special kind of LED light that has a built-in circuit board with light-emitting diodes (LEDs) for advanced lighting. These lights are mainly used in vehicles for turn signals, taillights, accent lighting, and other customizable lighting applications. One of the most recognized features of LED sequential lights is the dynamic and attractive light patterns they are capable of. When the turn signal is activated, the LEDs light up one after the other in a flowing or sweeping pattern. This not only looks great but also makes the signal more noticeable to other road users.
1. 12V vs 24V LED Modules
12V LED sequential turn signal lights are the most common and popular choice among vehicle owners. They are perfect for most car lighting applications, easy to install, and compatible with a wide range of vehicles. The 12V LED modules are available in a variety of styles, including one-row and multi-row layouts, with different shapes and light effects.
24V LED sequential turn signals are designed for use in larger vehicles like trucks and buses. Their higher voltage allows for longer runs of LED lights without significant voltage drop, making them suitable for larger vehicles with longer wiring lengths. The 24V modules are also designed to be more robust and durable, with features like enhanced weather resistance and protection against electrical surges.
2. Color Options
White LED sequential modules are the most commonly used for daytime running lights (DRL) and various other lighting applications. They provide a bright, clean light that enhances the vehicle's visibility and aesthetics. Some white LEDs may have a cooler or bluish tint (5000K-6500K) that distinguishes them from others.
Amber LEDs are mainly used for turn signals and side markers. They are bright and highly visible, making them the ideal choice for turn signals, as they can easily be noticed by other road users.
Red LEDs are used for taillights, brake lights, and accent lighting. They provide a warm and vibrant red glow that enhances the vehicle's visibility and style, particularly at night or in low-light conditions.
Sequential LED modules are also available in dual-color or RGB options. These versatile modules can produce a wide range of colors and effects, allowing for customizable lighting.
3. Number of LEDs
The number of LEDs on a sequential LED module can vary significantly, from a few to several dozen, depending on the size and intended use of the module. Smaller modules with fewer LEDs are suitable for use in tight spaces or as accent lighting, while larger modules with more LEDs provide more significant illumination and are ideal for primary lighting functions.
4. Waterproof Rating
Waterproof sequential LED modules come with an Ingress Protection (IP) rating. The IP ratings indicate the level of protection against water and dust ingress. For instance, IP65-rated LEDs can withstand water splashes from any direction and are also dust-resistant. They are suitable for use in most weather conditions. IP67-rated LEDs can be submerged in water for a short time and are completely dust-tight. These IP67-rated modules are used in extreme weather conditions or applications where immersion in water is possible.
Every sequential LED module has its specifications. The specification of an LED module determines its performance and application. Here are the key specifications to consider;
LED Type;
The type of LED used in a sequence matters. The type of LED affects the brightness and color quality. Some types of LEDs are SMD 5050, SMD3528, and SMD2835.
Voltage;
Every sequential LED module has a designated voltage. Common voltage options are 12V and 24V. The voltage affects the brightness and power consumption of the module.
Wattage;
The power consumed by an LED module is directly proportional to its brightness. Higher wattage modules are brighter. The wattage of a sequential LED module ranges from 0.24W to 2.5W or more.
Color Temperature;
Color temperature determines the color appearance of the LED light. LED modules offer different color temperatures ranging from cool white, warm white, to daylight.
Brightness (Lumen);
Brightness is an important specification of a sequential LED module. The brightness affects where the LED module can be applied. Higher brightness modules can be used in places with high ambient light. Brightness is measured in lumens, and the sequential LED module has a lumen range of 100 to 5000 lumens.
Beam Angle;
The beam angle of a sequential LED module determines the coverage area of its light. Modules with a wider beam angle have a broader coverage area.
IP Rating;
The IP rating of a sequential LED module indicates the level of resistance to dust and water. It also shows the ability of the LED module to withstand harsh environments. Higher IP-rated modules can be used outdoors or in industrial settings.
Cutting Length;
Some LED modules allow users to cut them into smaller lengths to suit different applications. The cutting length is specified in terms of the number of LEDs or the length in millimeters.
It is important to maintain the sequential LED module to prolong its lifespan and performance. Sequential LED modules have superior quality, so the maintenance process is straightforward. Dust and dirt are the primary enemies of LED modules. They can clog the light emitted by the LED module. The best way to get rid of dust and dirt is to use a microfiber cloth or soft brush. Wipe or dust the LED module regularly. Cleaning the LED module regularly will prevent the build-up of dirt and dust. If the LED modules are in a dirty environment, increase the frequency of cleaning.
Harsh chemicals can damage the LED module. Use only mild cleaning solutions or isopropyl alcohol to clean the LED module. Before cleaning, ensure the power supply is turned off. This will prevent electrical shock and damage to the LED module. Also inspect the wiring and connections periodically. Ensure all the connections are secure. Loose connections can cause flickering lights or module failure.
When buying sequential LED modules for sale, business buyers should consider the following:
