The Role of Sensors in the 21st Century
seven colors, automatically changing the LED bar or strip that is non- 23
adjustable. Also, it means an RGB color changing system, which
allows adjustment of color change frequency, strobing, chasing, and
other action modes.

1.11.19 SMD/SMT
SMD/SMT is a type of low-profile LED that is surface-mounted to a
PCB. These types of LEDs are very powerful and range in lumen out-
put from 35 up to 170 lumens. With the latest LED technology being
applied today, these have shown to have the most robust system,
delivering light levels and color consistency. These SMD LEDs are
usually in the 0.5-watt, 1-watt, 3-watt, and 5-watt power range.
In this instance, a 7-watt or 9-watt LED light will contain 1-watt
LEDs × 7, or 1-watt LEDs × 9, or 3-watt LEDs × 3.

1.11.20 SSL
SSL means “solid-state lighting.” It does not use heating of a thin frag-
ile filament to create light. Instead, it uses electrical current passing
through a chemical, which will then become excited and emit light.

1.12 Task Lighting-Lamps
A task lighting-lamp is an LED light used to specifically light a par-
ticular area used for work or reading. It is typically found in the form
of a desk, floor, or clamp-on lamp, and can be a high-powered LED
light in any form.

1.12.1 UV-A
UV-A is in the range of 315 to 380 nm and is also called “long wave”
or “black-light” since it is invisible to the human eye. It can cause skin
irritation and fading of fabrics.

1.12.2 UV-B
UV-B is in the range of 280 to 315 nm and is also called “medium
wave radiation.” It can cause severe damage to the skin and human
eye through exposure.

1.12.3 UV-C
UV-C is below 280 and is also called “short wave” or “germicidal” for
its ability to destroy even bacterial life forms. It is extremely hazard-
ous to all life forms due to its ability to cause immediate damage to
cellular DNA.
