LED: energy efficient green solutions


Dedication to innovation, advanced technology, and excellence in engineering has resulted in the next generation of outdoor LED fixtures from King Luminaire.

LED, which stands for "Light Emitting Diode", is a semiconductor device that emits a narrow

spectrum of light. King Luminaire’s goal in introducing LED technology is to provide customers

with a light source that matches or exceeds the performance of HID technology, while also

providing substantially longer life and cost effectiveness when compared to similar fixtures

utilizing a comparable HID light source.

With LED technology, as with HID technology, King Luminaire continues to provide outstanding

optical performance in terms of output and distribution. The performance of King Luminaire LED

fixtures is therefore designed around the requirements suggested in the IESNA RP-8 standard for

roadway illumination. This means that LED is treated as an ‘alternative’ source to HID and must

meet or exceed the same criteria as HID when it comes to the number of fixtures required, pole

spacings, Dark Sky Friendly™ design, etc.

LED technology is still in the early stages for general outdoor street lighting. Our product

development team is dedicated to continuous improvement of this technology to ensure that

all LED products from King Luminaire continue to overcome all inherent obstacles and deliver

excellent heat control, superior optical performance, and substantial

operational cost savings. King Luminaire will continue to offer the

highest quality product at a very competitive price.

LED: Dark Sky Friendly™

King Luminaire continues its tradition of supplying the highest performance while still addressing the demands of today’s lighting environment by minimizing glare, light trespass, and wasted uplight.

King Luminaire’s K902 LED fixture offers “Dark Sky Friendly™” characteristics, emitting little

to no uplight into the night sky. The flat lens offers full cutoff lighting classification emitting

no uplight.

The benefits of our Dark Sky Friendly™ fixtures are:

• Low glare for better visibility

• Little or no uplight for minimal direct contribution to sky glow

• Minimal light trespass to unwanted areas (homes, bedroom windows)

• Excellent uniformity

Although there are many facets to the demands being made of today’s luminaires, the main

ones are low glare, minimal light trespass and minimal uplight. The combination of these three

attributes is known as Dark Sky Friendly™. Low glare results in improved visibility because

the eye is not drawn to any bright points of light that can dazzle and prevent us from actually

seeing what is being illuminated. The absence of hot spots makes the lighting provided easier

to see by, and consequently improves security.

A luminaire that provides

controlled light minimizes light

trespass, which is brought

about when light falls on

areas we do not wish to light.

Direct uplight (that is light

from the luminaire itself)

can be minimized or even

excluded entirely by the

selection of a luminaire.


Heat Control• King Luminaire recognizes that the largest single contributing factor to LED chip failure is heat.

• Elevated junction temperatures at the LED chip can lead to reduced light output, as well as drastic

reductions in the expected life of the LED chip.

• King Luminaire’s K902 area light fixture utilizes a dynamic fluid cooling system for heat control.

• The fully enclosed, self-contained design of the LED Light Engine enables cool air from outside of

the fixture to be drawn upwards by convection around the internal heat sinks and flow out of the

fixture through our unique vented housing system.

• The self contained, fully sealed LED engine ensures full protection of the LED arrays from the effects

of the environment including dust and moisture.

• This highly effective, dynamic air flow system efficiently draws heat away from the LED chips, allowing

them to be kept well below the recommended heat levels for optimum performance.

Optical PerformanceKeeping with King Luminaire’s long-standing reputation as a quality manufacturer of high performance

street lighting, our new K902 luminaire is engineered to provide the highest degree of optical

performance in the market. The high precision, moulded optical lenses allow the directional characteristics

of LED to be optimized to provide the various light distribution to meet any lighting needs.

Environmental ConcernsKing Luminaire has kept environmental concerns in the forefront during the development of our LED

luminaires. In addition to the benefits gained from reduced energy usage, the direct nature of the housing

virtually eliminates wasted uplight above the fixture. The precision designed optics help reduce glare and

distribute the light evenly onto the ground plane, thus improving lamp spacing and lighting uniformity.

The high performance of the LED Light Engine requires that extra attention be paid to the thermal design, optical performance, and environmental concerns.
