Who is Beta - Kramer
• Beta-Kramer is a Ruud Lighting Company• Incorporated in 1982• Largest Privately Held Lighting Manufacturer in
the world• Complete line of LED outdoor (and indoor)
fixtures that set the industry benchmark for energy efficiency
#title#
Beta LED “Total Systems
Approach”
#title#
Key To Specifications & Evaluation
• Delivered Lumens• How To Compare to HID• How to compare to other LED
products
LED Overview
#title#
Lumen output – HID and LED
LED Overview
#title#
Why Use LED Luminaires?
• Increased Uniformity in Illuminating the Roadway– Lower Average Lighting Levels
– Maintenance of Minimum Lighting Levels
• Exceptionally Long Lives – 100,000 hours +– Much Lower Maintenance Costs
• Substantial Energy Savings– Not Uncommon to Achieve 50% savings from Current HID Lighting
Systems
• High Color Temperature White Light
– Studies Indicate Increased Visual Acuity
#title#
Products Available
• The Edge by BetaLED– Area Rectangular
– Area Round – Direct & Spider Mount
– Pedestrian Scale Pathway Bollard
– Security / Wall Pack
– Canopy
– Parking Structure
• LEDway Street Smart – Roadway Lighting
#title#
“Life”
• LED manufacturers are NOT consistent with life ratings
• IESNA 30% Lumen Depreciation
• Do you define “Life” by the robustness of the Driver?
LED Overview
#title#
Start with the Right LED
• High Brightness, Super-White
– 1 Watt per LED
• High Quality Supplier – Cree, etc.
• Output “watts” will range from 20 – 240 Watts (1-12 light bar modules)
Total Systems Approach
#title#
Light Bar
• 10 or 20 LEDs per light bar
• Modular Design
• Designed to grow as LED technology evolves
Total Systems Approach

Junction Temperature
What is Junction Temperature Tj ?
How is it measured?
LED Overview

LED Overview
#title#
Heat Sink
• Proper thermal management is key to low junction temps
• Thermal management = longer life
• Be wary of LEDs in traditional fixture designs

• Proper Management of Junction Temperature

• Open Mesh Design and Optimized Heat Management
Total Systems Approach
#title#
Junction Temperature Conclusions
• Be wary of LED’s in “traditional” fixture designs.
• The higher the junction temperature the lower the initial light output
• The higher the junction temperature, the faster the lumen depreciation (shorter “life”)
• Look for a fixture that is designed with sufficient heat sinking
LED Overview
#title#
Thermal Management
• Less Heat = More Light– Maximize Initial Light Output
• Less Heat = More Life– Minimize Light Loss Over Time
