Liter of Light brings brighter homes and future.

Feb 16, 2013


What is “liter of light”? It’s a clear plastic soda bottle filled with filtered water and bleach and installed in the roof as a skylight. The water refracts the sunlight as it streams through the bottle, dispersing the rays 360 degrees, thereby illuminating the entire room. The recipients of the solar bottle bulbs, who pay about $1 for the bulb installation, save money on electricity and cut back on the use of kerosene, candles, and other fuels that are responsible for indoor air pollution and fire hazards. – Illiac Diaz, activist and Filipino entrepreneur.

JCIP in partnership with My Shelter Foundation (headed by Mr. Illiac Diaz) aim to make brighter Filipino homes in 2013 in at least 100 cities and 10,000 households in the Philippines. It is the hope of 2013 National Chairman JCI Member Anna Lim-Santiago that this will be done through the efforts of JCI local organizations throughout the Philippines.

The Junior Chamber International Philippines (JCIP) has recently won the Best National Flagship Project for its Liter of Light Project. The award was given during the 2012 JCI World Congress held last November in Taiwan. The project bested more than 100 other national projects from all over the world.

To celebrate this feat, JCI Duwaling hosted a Victory Luncheon / Press Conference here in Davao City last December 29, 2012, 12 noon. JCI 2013 World Vice-President Bernard Dy and 2012 National Executive Vice-President Christine Garcia and JCI 2013 National Chairman Mem Anna Lim-Santiag all share their history, journey, triump and more future plans for the Project Liter of Light.

How to make solar bottle bulb (written)
Materials Needed:
·         1.5 or 2L na bote ng softdrinks
·         Mga piraso ng yero (Galvanized Iron corrugated sheets)
·         Tubig (purified/filtered) + cholorox/zonrox (bleach)

Step 1:  Gupitin ang yero sa sukat na 1 ft x 1ft. Maaring flat or corrugated depende sa bubong na pagkakabitan.

Step 2: Gumupit ng bilog sa gitna ng piraso ng yero ayon sa sukat na 2mm mas maliit sa katawan ng bote (gumawa ng bilog na panukat/pattern)

Step 3: Gupiting paikot ang 2mm mula sa butas at tiklupin pataas upang magmukhang ngipin ang gitna ng yero. Ito ang kakapit sa bote pagkakabit.

Step 4: Lagyan ng rubbery sealant or epoxy resin ang mga ngipin sa yero at idikit sa bahagi ng bote na 1/3 mula sa takip.

Step 5: Pagkabit sa Bubong:
Butasan ang bubongan sa eksaktong (sukat ng panukat mula sa Step 2)

Step 6: Ilapat at idikit ng maigi sa butas sa bubong ang Solar Bottle Bulb.

Step 7. Pahiran ng tamang dami ng rubber water sealant ang paligid upan maiwasan ng anumang pagtulo sa bubong.

Step 8: Magdrill ng 6 na butas sa palibot ng piraso ng yero upang masiguradong maigi ang pagkakabit ng Solar Bulb sa bubong.

Step 9: Lagyan ng 10ml ng chlorine (bleach) at punuin ng tubig (purified para maiwasan ang paglabo ng likido.)

Step 10: Isara ng maigi ang takip

Step 11. Para pigilan ang pag-crack ng takip ng bote, kumuha ng piraso ng plastic PVC tube (haba 1.5inch x lapad: 1.25inch) itaklob sa takip ng bote at lagyan ng sealant ang ibabaw

Step 12: at hayaang sumilip ang liwanag ng araw.
