Lighting education
in India is at a very novice stage. Post Graduate Programme
in Lighting Technology
Management
is the need of the hour. The scope of the lighting research
is to incorporate the art, science and technology of lighting,
application of technology, essentials for the design, installation
and operation of a suitable lighting system. 26% of the world's
electric energy generation is spent on lighting alone. This
is going to increase with the lighting penetrating in video
projection, cinema projection, biological lights, aqua & tissue
culture, and environmental pollution control.. The India
is on the move and the economy is healthy and stable. With
an
estimated GDP growth of about 8 % every segment in industry
is experiencing healthy growth figures. It is no wonder therefore
that the lighting industry has experienced a welcome shift
in consumer demand over the last three years.
Government of India has recently liberalized its trading policy,
which has opened the doors for international organizations
wanting to enter the Indian US$500-million-a-year lighting
market The current scenario and the growth rate of the Indian
lighting market is visible from the following figures
The above figure
clearly indicates that the Lighting Industry in India is
in its maturing stages. With an estimated market
of over Rs.8600 crores the industry is witnessing tremendous
growth. During the last three years the lighting industry
has adjusted and considerably modified its approach in order
to remain competitive in an increasingly open market scenario.
-
Rs. 1250
crore industry (US $ 290 mn) in 98-99, with 20%
of turnover coming from the unorganised sector.
-
Imports < 5%..
Around Rs. 50 crores (US $ 11 mn) in 97-98. Exports
around Rs. 30 crs (US $ 7 mn) in 97-98
-
Technological
sophistication
is still in its infancy stage
-
Lighting
industry in India is seven decades old and has gone through
a
period
of transition
and growth
-
Lighting
load is approximately 17% of the total connected load
- around 100,000 MW for
the year 2000
-
The
industry has developed from being an importer
of lighting
systems to a self sufficient, indigenous
producer of lighting systems
ULTRA
VIOLET (UV) LIGHT & its
Applications
Ultraviolet
(UV) radiation is electromagnetic radiation of a wavelength
shorter than that of the visible
region,
but
longer than that of soft X-rays. The name means "beyond
violet" (from Latin ultra, "beyond"),
violet being the color of the shortest wavelengths of
visible
light. Some of the UV wavelengths are colloquially called
black light, as it is invisible to the human eye. Some
animals, including birds, reptiles, and insects such
as bees, can see into the near ultraviolet. Many fruits,
flowers,
and seeds stand out more strongly from the background
in ultraviolet wavelengths as compared to human color
vision.
The Sun emits ultraviolet radiation in the UVA, UVB,
and UVC bands, but because of absorption in the atmosphere's
ozone layer, 99% of the ultraviolet radiation that reaches
the Earth's surface is UVA.
Applications : Pest Control, Spectrophotometry, Analyzing
minerals, Biochemistry, Photolithography, Sterilization,
Disinfecting drinking water , Food Processing, Fire detection,
Telecom Application, Industrial Purpose,
Defense / Warfare Applications.
INFRARED
(IR) LIGHT & its
Applications
Infrared
(IR) radiation is electromagnetic radiation of a wavelength
longer than that of visible light, but shorter
than that of microwave radiation. The name means "below
red",red being the color of visible light of longest
wavelength. Infrared radiation spans three orders of magnitude
and has wavelengths between approximately 750 nm and 1
mm.
Applications: Night vision, Digital Cameras, Thermography,
Heating, Communications, Spectroscopy
