1.1 Do LED street lights (public lights) emit more blue lights than other sources, and does this lead to sleep disruptions?
There should be no worries regarding blue lights
emitted from LED street lighting on sleep
disruptions. There is nothing different about the
blue light from LEDs vs. other light sources, as
also discussed by the US Department of Energy. In
fact, the current level of blue light is equal to
or lower than moon light, which shines at 4000K.
What's more important is the intensity of light at
night. Disruptive effect depends heavily on the
amount of light, the timing, and duration of light
exposure. Research shows that the light levels
produced by LED street lighting are too low to
affect the hormone levels governing our sleep
behavior.
1.2 Will applying LED street lights lead to
circadian disturbances?
No. If properly designed and applied, LED lighting
will provide its advantages and you can avoid
potential unwanted side effects.
If you apply the right light, in the right place,
at the right time, for the right situation, LED
light can positively impact public safety and
livability while also offering savings on energy
and maintenance. Philips Lighting solutions are
carefully designed for local applications taking
into account the right optics and light intensity
to benefit from the LED advantages and mitigate
negative effects like circadian disturbances and
glare.
1.3 What's the health impact of blue
lights?
Blue light is important to our health and
well-being, especially during day-time. Much of the
research regarding potential negative health
impacts of blue lights are based on intensity and
duration of light exposure at night associated with
shift work. These levels of exposure are
significantly higher than common outdoor lighting
applications and cannot be extrapolated to the
reduced light level and shorter duration activities
associated with street lights.
2. Well-designed LED street lighting
2.1 Will LED street lighting lead to light
pollution?
The use of LEDs does not lead to more light
pollution, not if the lighting application is
well-designed. On the contrary, when applying
well-designed LED street lights you can be sure to
effectively control scatter and glare while having
far greater impact on reducing high angle
brightness and light pollution.
2.2 How can controls and optics help against the
negative effects of public lighting?
Controls such as dusk-to-dawn sensors can automatically adjust the lighting according to the time of day, not only reducing energy, but also reducing the potential negative environmental impacts. Likewise, you can implement shields to curtail uplight and sidelight, and most importantly, "optics" to minimize/reduce glare regardless of the amount of blue light or color temperature they deliver.
