Engineered Bottle Light - For Free natural sunlight inside your home!
This Bottle light is an engineered version of the soft drink bottle light innovation for tin shed. This bottle light can be embedded into RCC roofs to get free natural sun light for life inside your home without using electricity during day time!

Background

This concept was inspired from the 'Coke Bottle Light' that are used in housing projects in Asia and ASEAN nations.

However, we have engineered this concept to make it into a reliable, low cost and rugged solution, with care taken in the design to even replace the bottle in case it is broken accidentally after construction.

The design takes into consideration the common concerns and details for execution in a typical house with RCC roof construction. This can be adapated to other roofing technologies as well!

Bottle Lights embedded into RCC Roofs, can draw
in natural sun light - Free Light for life for dark
lit corners of your building!
The system consists of a metal cage designed to be perfectly sized for the pickle jar to be embedded into the RCC Roof. The cage has features that help it permanently lock into position the location of the bottle inside RCC. The cage also has a function to prevent accidental breakage of glass and acts as the first line of defense to the glass bottle.

Next, the Centring wood piece is specially designed to hold the bottle in exact elevation inside RCC so as to provide perfect spacing below the roof, to let out adequate light, and yet provide sufficient margin for covering up of the typical plastering done on RCC roofs.

The Bottle and the CNC-Router cut Plywood jig to hold it in position.

The Plywood place holder in-place along with the
roof-centring sheets. Then the RCC iron rods
are inserted around the bottle.

Roof is getting cast, with bottles in designated positions.

15 days after roof is cast, and with adequate
curing the supports from the bottom of the roof is
removed. Bootle Light reveals itself
