DSEM LED Array is one of the first LED array COB solutions for SSL. In DSEM, we produce High Efficient and High Quality White Light Engine. Our mission is to deliver solution with best efficacy and cost to our SSL customer. In DSEM, our white light engine are high efficient in lumen/watt and excellent quality in correlated color temperature (CCT) consistency covering from super warm white 2700K to super cool white 6500K. DSEM LED Array is a combination of creativity in packaging and innovation in technologies. DSEM appears to be the LED Array supplier to global market typically in Europe, Unites States, Japan and China for general lighting, commercial, residential and streetlight application.
DSEM LED Array White LED is created with blue Indium-Gallium-Nitride (InGaN) LED array with phosphor coating to create white light. DSEM LED products offering cool-white, neutral-white and warm-white LEDs enable lighting engineers for various applications. DSEM offers the full spectrum of white LED lighting from 2650K-7000K
Wide range of color temperatures
Optics integration solution Photon is the terminology for light. In DSEM LED Array, we extract every single photon emitted from the LED array to light up your life. We have optimum optics design and simulation tools to allow all light emit from the package. In our new JLED series, we have the integrated optics that enhances higher light output.
Excellent Lumen Maintenance with DSEM Thermal Management Lumen maintenance is the terminology commonly used to compare the amount of light produced from a light source when it is brand new to the amount of light output at a specific time in the future. Lumen is the photometry unit for brightness of light source. For instance, if a luminaire produced 100 lumens when it was brand new and now produces 70 lumens of light after 30,000 hours, then it would have lumen maintenance of 70% at 30,000 hours. The requirement of lumen maintenance target is usually based on the end user application and the requirements predefine by customers.
Managing the heat emitted from the LED chip is the main design consideration to have excellent lumen maintenance. Advanced Metal Substrate (AMS), DSEM patented technology, is the best solution to date with lowest thermal resistance. DSEM AMS package can achieve as low as 0.25 K/W. A low Thermal resistance package allows quicker heat dissipation to maintain the junction temperature of the LED chips at lowest. This will enable the LED chip to maintain its performance for longer operation hours.
Advanced Metal Substrate (AMS)
AMS provides superior thermal properties with the embedded integral aluminium heat-sink option: ceramic matrix, very thin, low profile. High speed with the special via built of full aluminium of very low inductance. It can be fabricated with high routing density - metal layers having copper signal layers of <1/1 mil line/space. Apart from high power LED application, its superior thermal performance can be used in other applications such as for RF products, strip lines, wave guide structures and controlled impedance lines.
Main Advantages:
Reduced Thermal path on selective dielectric.
High routing density - metal layers having copper signal layers of <1.1 mil line/ space
Integral dielectric - no delamination
RoHS compliant
The technology is protected by several patents
In AMS, no via drill and plating is required - the via is of solid full aluminium and the dielectric is of a high quality ceramic nature. The process is simple and low cost, and contains a low number of process steps.
The AMS technology serves as a wide technology platform, and can be implemented in various electronics packaging applications such as for RF, SiP, 3-D memory stacks, MEMS and high power modules and components.
