From color variation and dimming to new applications and beyond, innovative improvements on LED lighting management systems appear every day. Some of the most important of these advancements include developments in energy efficiency and output. With continuous increases in efficiency comes lengthier lifespans of LED products, keeping these lighting fixtures and LED drivers functioning in the homes and businesses of consumers for far longer than ever before.
LED lighting products are progressively more reliable, easily becoming a go-to solution for cost-effective, efficient residential and commercial lighting. Advancements have not yet solved all issues with LED lighting—such as those regarding thermal management heat dissipation—but implementing a few simple changes can turn headaches into solutions.
One of the largest changes to LED lighting systems is their increased capacity to create large amounts of energy without overheating. Most LED lights produce upwards of 350 milliwatts of energy, equating to approximately 70 percent heat output and 30 percent light output. The high temperatures resulting from heat output lower LED efficiency and make the products less dependable, thus creating a great need for thermal management and heat dissipation solutions.
With the transparent resin that encapsulates LEDs as a poor thermal conductor, and the back side of an LED chip generating heat from electrical energy not transformed into useful light, among other concerns, it is necessary to lower the overall operating temperature of LED lighting management systems. In order to create a more optimal “low junction” temperature, heat removal can be accomplished through passive thermal design. This includes:
The regulation of heat is referred to as thermal management. Thermal management represents a significant achievement in terms of the efficiency of LED lighting management systems and can be accomplished in myriad ways. Combinations of heat dissipation tactics allow for thermal management of not only the LED light bulb itself, but also that of other critical LED components of the lighting fixtures as a whole. This improves overall efficiency and the lifespan of LED lighting management systems.
The relative “newness” of LED technology means that design flaws, manufacturing defects and the eventual end-of-life phase of LED components have all been scrutinized to overcome and improve the lifespan of LED lighting management systems. Though progress has been made, the electrolytic capacitors of LED drivers—among other components—continue to provide lifespan challenges. There are effective solutions to help consumers overcome this and other challenges, including evolutions in efficient design of components and systems to improve functionality, monitoring manufacturing methods to keep defects at a minimum, and providing thermal conduction paths and heat sinks in appropriate locations to aid in cooling and heat dispersal. Ensuring capacitors are situated so as to avoid surrounding components’ heat by radiation, keeping other heat-generating components away from the underside of the capacitor, and using a convection cooling or fan in the power supply all aid in thermal regulation and heat dissipation, decreasing wear and tear.
While all of these solutions improve functionality and the overall lifespan of LED fixtures and lighting management systems, they are not enough to address the overall reliability of LED drivers. Continued improvements are being made, and an innovative new product from GRE Alpha is helping to bridge that gap.
GRE Alpha has developed a new, ultra-reliable, 300 watt LED driver—the XSP 300—a new generation product that will be unveiled at the Hong Kong Lighting Fair held from October 27 through October 30, 2016. Heralded as the world’s most rugged 300 watt LED driver, the XSP 300 features patented thermal-core technology and temperature-sensitive components for an 80C full load. This advanced thermal core technology, paired with applied advanced electronics, means that GRE Alpha’s XSP 300 has been able to overcome previously unsolved high thermal stress issues. It is idea for installation in signage, architectural and high power LED applications.

Modern technological advancements in LED lighting management systems have revolutionized the lighting industry, providing highly improved performance, enhanced efficiency and economically viable lighting solutions for both residential and commercial applications. In last month's post, we introduced our 0-10V dimming module and digital addressable lighting interfaces (DALI) dimming module, two LED lighting components that offer true innovations in dimming control for projects of varying size and scope. Working alongside those components is the digital multiplex (DMX) control, a key element implemented in color mixing applications and the newest innovation in GRE Alpha's LED lighting management system offerings.
Transitioning from traditional lighting systems to LED lighting was the first step in lighting management system evolution. That was followed quickly by the need for dimmer switches for the much brighter, more efficient residential and corporate LED lighting solutions. As LED lighting systems have evolved and become more widely adopted, and the number of new applications for LED lighting continue to evolve, color mixing opportunities have also increased. This is where DMX lighting control protocol becomes important.
DMX is a standard element of digital communications often used for lighting stages, building façades, entertainment and other systems requiring coloration effects. As pricing for LED lighting with color has decreased, LED color mixing has seen an increased demand for use in architectural and residential applications. Both use the DMX lighting protocol to create environmental moods, enhance productivity and provide simple, flexible lighting control applications.
Boasting a simple plug-and-play design that works with CV systems, GRE Alpha's DMX dimming module can upgrade existing non-dimmable systems to work with DMX lighting protocol - simply by adding the dimming module. It follows the latest DMX 512-A protocol, the current standard for manufacturing and intensities as set by the Entertainment Services and Technology Association (ESTA). Adhering to DMX 512-A protocol allows the GRE Alpha DMX product to seamlessly integrate with existing DMX-enabled control consoles and dimming panels.
Additionally, GRE Alpha's DMX dimming module is remote device management (RDM)-enabled, allowing for simple, two-way communication between DMX devices and lighting consoles. Unlike other DMX dimming modules, GRE Alpha's DMX dimmer uses a 4-in-1 LED chip that offers four color channels - red, green, blue and white or amber (RGBW/RGBA) - instead of the basic three-channel red, green, blue (RGB)color control. This gives users four types of colors to mix for proper ambiance, allows for precise control of the white/amber color and affords the option to create a wider range of customized color shades. The GRE Alpha DMX dimming module is at the forefront of color application in LED lighting management systems. As costs for color variation continue to become more efficient, the LED lighting industry will continue to produce color mixing DMX lighting options for the masses.
GRE Alpha has launched three new products this summer and is not done yet. In addition to the 0-10V dimming module, the DALI dimming module and the DMX dimmer, there is yet another product coming soon to the GRE Alpha line. Stay tuned for updates as the summer continues.
