The invention relates to a fan and light emitting device capable of being mounted on a ceiling of an accommodation. The fan works under the mechanism of Coanda effect to diffuse air. The design of this fan is approximately circular with air discharging ring at its circumference and a usable space at its centre. A light emitting means is positioned in this centre space. This central position of the light emitting means makes the room brighter and does not compromise on the functioning of the fan. The entire device is located within housing. A common electric driver can be included in the housing to drive both the fan and the light emitting device. Optionally, a common back up power supply means may be provided in the housing to provide power back up for the fan and/or light emitting device.

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
