Wireless Lighting
General
For a light to be wireless, it
requires two elements; wireless power and wireless control. There are many types
of wireless control; radio frequency, infra-red, W-DMX, Bluetooth etc., all
with varying operational ranges. In order to control a wireless light, the
light fixture must have an antenna, and to power a wireless light, there must
be a rechargeable battery/pack within its housing.
Wireless Control
Infra-red (IR) control typically
has a short range of approximately 10m. The sub-division of IR used to control
wireless lights is known as near-infrared (NIR) and it works on the 0.78-3µm wavelength.
Radio frequency (RF) control has
very large range of approximately 300m. There are many different frequencies in
the radio spectrum. Astera works on the ultra-high frequency between 860MHz
(EU) and 915MHz (USA), and later will switch to the much more stable 2.4GHz
frequency for both regions.
Wireless-DMX control can be
achieved by using a wireless DMX transmitter (Astera’s ART3 is suitable) with
any standard DMX setup desk. Alternatively, Astera’s X-Series lights can be
controlled using CRMX Wireless DMX from Lumen Radio.
Wireless Power
Rechargeable batteries are a
requirement of wireless lighting. The longer the charge is held and the more
charging cycles the battery has determines the quality of the battery. Many
wireless lights (and other consumer electronics) use lithium-ion batteries as
they have one of the best energy densities, no memory effect and a slow
discharge rate when not in use. Compared to lead acid batteries, lithium-ion
batteries are far superior due to the lighter weight and longer use. However,
Astera uses lithium-nickel-manganese-cobalt mixed cell batteries, which
perfectly combines optimal volumes of each element to considerably lower the
energy density and increase the lifespan and safety of the battery.
For the X-Series, Astera uses ultra-long-life
Samsung batteries to support the extremely bright Cree and Philips LEDs being
used. These LEDs require more power to prolong the fixtures’ runtime.
