SunBeamer daylighting
Details
The world's first intelligent sun tracker delivering full-spectrum sunlight. Tracking is performed autonomously using an onboard GPS and stepper motor that follows the sun throughout the day. Reflective louvres pan and rotate, redirecting 100CRI sunlight as a stationary beam with 99% of the UVs removed. Traditional skylights and windows are limited to the perimeter and top floor of buildings. They struggle to provide consistent, glare-free daylight and introduce unwanted heat gain. The SunBeamer, encased in a sealed enclosure is installed as a standalone unit or in an array configuration for mounting in an atrium or overhung on the building's edge delivering a collimated beam up to 200m (600ft).

Operation
• An array of reflective mirrors that pivot and rotate collecting and redirecting sunlight.
• A combination of software and motor to track the sun in real-time via an onboard GPS.

Application and usage - Overhung
Ground and lower levels of a building are typically areas where sunlight is most restrictive. This could be due to the building's envelope or overshadowing by neighbouring buildings and nearby structures. For an existing building, a retrofit installation can be done with overhung SunBeamers on the rooftop with the concentrated sunlight redirected internally with reflectors or light tubes.
New buildings or when building space allows, internal light wells are used. SunBeamers are mounted on the rooftop for the sunlight to travel down the light well then redirected with reflectors or light tubes to the areas or rooms where the sunlight is required.
Application and usage - Atrium
This is the easiest and most cost-effective method to introduce sunlight into the indoor environment. From the atrium, sunlight is directed as a collimated beam or diffused with lenses to spread the light into the space. Full-spectrum sunlight is delivered to support green growth, minimise artificial lighting usage, showroom showcase or provide comfortable glare-free daylight inside conference centres.

Application and usage - Tunnels and subways
Daylight into underground environments can be achieved by tunnelling sunlight through light tubes. The light tubes can be translucent emitting light 360° or closed transmitting maximum light at the endpoints. This technology is combined with LEDs as a hybrid system to bring consistent light levels throughout the day and artificial lighting for night times.
Application and usage - Alleyways and grey areas
Overshadowing is common in many cities preventing sunlight from reaching street level. Darkened environments limit plant growth and plant variety, which can also affect the growth of native plants in the region.
Alleyways, recreation areas and other spaces that were once enjoyed become neglected and turn into grey areas that are avoided and even become unsafe. SunBeamers mounted onto building edges can direct sunlight to ground level and bring life into these grey areas and spaces.
Concentrated sunlight
• Collimated beam 0.50° beam spread.
• Up to 200m (600ft).
• Programmable beam of sunlight.
• 99% of UVs removed.
• 60% of heat removed.
Redirect the sunlight
Utilizing a variety of reflectors, lenses and diffusers to distribute and redirect sunlight opens up indoor spaces for green areas, green walls or indoor landscaping with a welcoming and happier environment.
• Diffuse the sunlight beam up to 30°.
• Redirect the sunlight beam to where you need it.
• Reflect sunlight with reflective mirrors up to 30m (100ft).
Designer flexibility
Architects and designers have the freedom to add visual aesthetics with custom designed pendants. Each pendant can be customised to fit in with the building's design to diffuse sunlight and create striking lighting effects.
Efficiency
The mirrors inside the SunBeamer are adjusted to perform at maximum during the times when the sun is rising and setting. As the sun is brightest at midday we can allow for a little decrease in performance as there is a considerable amount of sunlight to harness. The below illustrations demonstrates the performance, based in Melbourne, Australia in the month of March during autumn (fall).
