KEEP IT COOL!

Active cooling gives the Sportsbeams LED fixtures amazing versatility

 
 
CONSTANT TEMPERATURE

Our intelligent active cooling maintains consistent temperature for the LEDs and circuit board.

OVER 490,000 HOURS MTBF

Our fans have been on the market for decades and have a proven MTBF rate of over 490,000 hours.

OVER 40% WEIGHT REDUCTION

No big hunk of metal weighing our fixture down. That means little modification to existing structures.


WIDER OPERATING RANGE

Active cooling allows our fixture to operate in a wider range of environments, from extreme heat to bone-chilling cold.

AIM IN ANY DIRECTION

A passive heatsink must be aimed a specific direction for airflow. Our lights operate in any direction for maximum versatility.

MONITORING INTELLIGENCE

Our built-in intelligent system monitors and logs fan speed, operating temperature and much more.

ACTIVE VS. PASSIVE COOLING

Our Sportbeams 1500 LED is a powerful light. It delivers over 180,000 lumens. Naturally, the advanced components we use are temperature sensitive. So, we had a choice. Use a big, dumb chunk of metal as a heatsink or put our onboard intelligence to work with a fan.
The choice was obvious. With active cooling, we were able to increase the lifespan of the fixture, significantly reduce weight, allow the fixture to be mounted at any angle and increase its ambient temperature range.

ACTIVE COOLING SAVES THE DAY

FEAR OF FANS
Fans. It’s almost a four letter word in the LED lighting world. Light designers almost universally believe that a fan incorporated into an LED fixture will be the first failure point, especially when compared to all of the solid state components.

This seems like a rational notion and there are some obvious cases where this has been true. But, with solid design application and proper component selection, fans can provide far more benefits than risk.

EXCESS HEAT = FAILURE
When looking at the MTBF of most systems, it is usually the heat sensitive components that fail first – i.e. LEDs, electrolytic capacitors, and semiconductors. For every 10° C rise in temperature there is a 50% reduction in the life of the semiconductors. This requires that a fixture’s heatsink be overdesigned or at least, designed for operation at the highest possible ambient temperatures.

There are other factors, however, that can increase susceptibility to heat damage and are not always accounted for in heatsink design. All heatsinks lose half of their efficiency at high altitude. Lights need to be dimmed down to half power to keep components safe, which means that twice the number of fixutres are needed to maintain consistent light levels.

EXCESS COLD = FAILURE
When ambient temperatures are extremely cold, LED’s forward voltage requirements go up as a function of physical temperature. Consequently, the voltage required to light an LED fixture may be so high that it exceeds the voltage available from most power supplies and the fixture will not light quickly or possibly at all. The large heatsinks, designed to meet extreme ambient heat requirements, don’t allow the LEDs to lower forward voltage requirements enough in order to generate full power. Now the fixture is caught in a loop that can’t be resolved until temperatures rise.

LOSE THE WEIGHT
The weight of the heatsink itself is often prohibits new LED fixtures from being drop-in replacement for antiquated systems. The total weight and size of the LED fixtures can render the existing infrastructure inadequate if the heatsink is much larger and heavier than the legacy equipment that it is replacing.

KEEP COLOR CONSISTENT
Finally, passive cooling can also have a noticeable effect on the fixture’s color temperature. Changes in the physical temperature cause real changes in the color temperature and this occurs regularly in passively cooled fixtures.

BEST SOLUTION
SportsBeams’ patented, closed-loop, fan cooled fixtures solve all of these problems. It uses the same type of exterior-rated fans that have been used in telecom, traffic, and industrial control systems, 24/7, for years and has a 70,000 hour warranty.

The lower weight of this intelligent thermostatically fan cooled system allows for longer fixture life, higher ambient temperatures, lower fixture weight, color maintenance, quicker cold weather heat-up, and a proven MTBF of over 400,000 hours.

INTELLIGENT MONITORING
In the rare event that a fan fails, it can be easily replaced without tools. It is doubtful that this will happen because the user will have been alerted to this pending failure well in advance by SportsBeams’ smart light technology that monitors fan RPMs and fixture temperatures before it ever becomes a problem.

MAINTAINING A CONSTANT TEMPERATURE

AMBIENT AIR IS DRAWN IN

The fan in the rear is intelligently controlled to pull ambient air in at a rate that maintains consistent temperature. If it’s colder outside, it spins slower. If it is warmer, it moves faster.

FINS DRAW OUT HEAT

Heat from the light and drivers flow to the fins. Air drawn in from the fan carries it out of the the fixture.

CONTINUOUS COOLING

And on it goes. Sometimes air is flowing fast and sometimes slow. But all the sensitive components are kept a comfortable 70° C.
