incubators and radiant warmers. The Arm attached to the Rollstand, can be
used for infants in a bassinet, incubator, open bed, or radiant warmer.
There are two intensity settings, high and low. The desired setting is selected
using the buttons on the control panel of the light. The light output was factory
calibrated with the neoBLUE®Radiometer to provide an initial intensity of 35
µW/cm2/nm at the high setting and 15 µW/cm2/nm at the low setting at a
distance of 35 cm (13.75 in) from the light enclosure to the baby. The light
output can also be adjusted. The lower portion of the enclosure includes a
built-in lens which protects the light from incidental debris or fluid exposure.
The blue LEDs emit the majority of light in the range of 450 –500 nm (peak
wavelength 450-470 nm). This range corresponds to the spectral absorption
of light by bilirubin, and is thus considered to be the most effective for the
degradation of bilirubin. Blue LEDs do not emit significant energy in the
ultraviolet (UV) region of the spectrum, so there is no UV exposure to the
infant. In addition, blue LEDs do not emit significant energy in the infrared
(IR) region of the spectrum, minimizing concern about excessive warming of
the infant. The blue LEDs are mixed with a small amount of light from the
white LEDs to soften the appearance of the blue light for sensitive individuals.
As with all phototherapy lights, protective eyeshades must be used to protect
the infant’s eyes from excessive light exposure.
The neoBLUE compact light is also equipped with a white exam light feature
that provides approximately 10,000 lux of neutral white light for general
examinations.
LEDs have minimal light output degradation over their lifetime with proper
use. Nevertheless, the user can adjust the output of the LEDs for any
degradation using the control panel of the light. The light is expected to
operate on factory setting intensity levels for over 40,000 hours. Actual
results may vary based on environmental factors and intensity adjustments.
Treatment and Device Timers
The neoBLUE compact light is equipped with a treatment timer to track the
total number of treatment hours per patient, and a device timer to track the
total number of hours the blue LEDs operate. The treatment timer is located
on the control panel and can be reset by holding down the reset button next
to the display. The device timer is located on the underside of the light near
the LEDs. To reset the device timer if LEDs are replaced, please refer to the
Service Manual. The timer will count up to a maximum of 99999.9 hours. The
timer will count at the same rate regardless of the intensity setting at which
the device is being used. The last digit refers to tenths of hours, with 0.1 = 6
minutes.
Power Requirement
The light is mains-power operated. The power cord plugs into the power inlet
at the side of the light enclosure; or into the power inlet located on the Arm
when attached to the Arm or Rollstand. The other end of the power cord is
plugged into the wall receptacle. Power transform in different regions is
accomplished internally and automatically by the power supply unit built in the
light device. There is a Power Supply Connection Indicator on the keypad
control panel that glows green when power is supplied to the device.
