Abstract
"The ""ADEQUACY OF ARTIFICIAL LIGHTING IN LIVING
ROOM AND STUDY AREA OF URBAs' RESIDENTIAL HOMES IN
DHARWAD CITY, KARNATAKA"" was undertaken during 1998-99. The
objectives were to determine the existing intensity of artificial hghting and
compare with the recommended standards and to know the awareness with
regard to adequacy of artificial lighting. Data were collected from the
different socio-economic groups as classified by HUDCO (1998) as low income
(Rs.2100-4500 per monthi. middle income CRs.4.500-7500 per month) and high
income (more than Rs.75CO per month). Thirty households from each income
group were selected by stratified random sampling method. The
questionnaire-cum-iiiter%-ew method was used to collect data from the head
of the households and the respondents. The intensity of artificial hght in
living room and study area were measured by using Digital Luxmeter (TES
1332) between 7 to 9 p.n:. The living room was divided into 20 equal parts
and study area into 4 equal parts. Luxmeter was kept horizontally at the
centre of each part and mean intensity of artificial light was calculated.
The salient fndings were that majority of the households used
fluorescent tubes in Uving room compare to incandescent bulbs. Irrespective
of the income groups. aJl the households used general lighting arrangements
in hving room and study area. Mean intensity of artificial lighting in living
room and study area was 69.28 and 72.04 lux. which was highly inadequate,
compared to the recommended standards of 300 lux for living room and 150
lux for study area. The intensity of artificial hght in living room and study
area was shghtly higher in high income group i.e. 72.56 and 74.13 lux
compared to middle iacome. 68.22 and 68.88 lux and low income group, 68.47
and 68.04 lux respectively.
Hence the adequacy, type and proper arrangement of artificial
lighting in home needs to be improved for the health, comfort and well being
of family members which presently famihes are unaware. The usage of
fluorescent tubes and adequate task lighting were suggested which lasts
longer and also conser\-e valuable energ}-."
