LED lighting technology has advanced leaps and bounds over the past few years and is continuing to grow as a primary light source for a variety of applications. Amongst the many solutions available, one of the most versatile and durable solutions is that of the SI-B8U15156CWW series of COBs (Chips On Board). This article will explore the application field and working principle of the SI-B8U15156CWW series COBs.

What is a COB?

Before diving into how the SI-B8U15156CWW series works and in what application it may be used, it is important to understand what a COB is. COB stands for \'Chip on Board\' and is a technology developed by LED manufacturers to increase the performance and lifespan of LED lightbulbs or COB modules. It is essentially a substrate combined with LED chips (typically 10-100’s of milliwatts) that are placed directly on the circuit board in an array pattern.

By doing this, the LED manufacture is able to benefit from improved thermal performance and cooler operation as the substrate transfers the heat from the LED chip. This in turn increases the lifespan of the bulb and provides improved efficiencies of up to 50%. The substrate is typically ceramic or aluminum, which keeps the chips in place, while still allowing a small amount of efficient cooling between them. As a result, COBs tend to be significantly more efficient than normal LEDs.

The SI-B8U15156CWW Series

The SI-B8U15156CWW series are a range of low-cost, high-power COBs, suitable for a variety of different applications. These COBs employ high-power flip-chip technology made from high-rejection chips and are easily configured for different lighting situations. The array of chips on the board can be used as an engine or module with multiple LEDs on the same motor, allowing for greater power output, flexibility and scalability for different lighting solutions. Based on the type of LED chip used, these COBs can deliver up to 3.2W of power with an output of 50-250 lumens.

The SI-B8U15156CWW series provide a wide range of application fields, including but not limited to residential, commercial and industrial lighting, as well as lighting for transportation, agriculture and healthcare. In addition, they are suitable for both indoor and outdoor use and can be used in a variety of different lighting fixtures and configurations.

Mode of Operation

The SI-B8U15156CWW COB series operates in two different modes: continuous and switched. The continuous mode is typically used and requires the user to set a specific current value by adjusting the onboard potentiometer. This is done to ensure the LED chips on the board are running at the optimal current for maximum efficiency and longevity. This mode is useful for those applications that require a constant light level.

The second mode of operation is the switched mode. This mode requires the user to turn the power on and off manually by adjusting the onboard switch. This is useful for applications where the intensity of the light needs to be changed, as the user can adjust the current setting without having to change the physical setting of the potentiometer. This mode is also beneficial for applications where the user needs to adjust the light intensity on the fly.

Conclusion

In conclusion, the SI-B8U15156CWW series of COBs are a low-cost, high-power solution perfect for a variety of indoor and outdoor applications and fixtures. Their ability to be switched between continuous and switched modes makes them incredibly versatile, enabling them to be used in a variety of different lighting scenarios. With their high power output, they offer superior efficiency and reliability when compared to normal LEDs, making them a great option for a variety of lighting applications.
