CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
The present application does not claim priority from any other patent application.

TECHNICAL FIELD

The present subject matter described herein, in general, relates to a mechanism of mounting the lighting means on the flat surface to increase the intensity and efficiency of quantum of light, more particularly relates to a lighting assembly for unidirectional propagation of light and method thereof.

BACKGROUND

Many electric or electronic components or lighting means such as Light Emitting diode (LED), a halogen lamp, a mercury bulb, incandescent bulb or any other diodes or lighting devices produces light form one side and heat form other side when such lights are switched on upon application of current.

Use of LED in lighting system is increasing day-by-day because of their optimum brightness levels as output. LED lighting system which is based on LED chips, are made from Gallium-Indium type PNP Diode junction. Upon application of direct current, they emit light along with radiant energy. As one side of the chip has to be mounted on holding surface, the mounting side of the chip, light on mounting side is converted in to heat. While the other side coverts most of the electric energy to light.

All these chips/lighting means have to be mounted on flat surface for the following reason:
• Led chips produce light from one side and from other side it produces heat. This heat has to be removed, else its own heat has the potential to burn, erode and finish the chips life.

• LED chips produce light in one direction only. This means to get the most efficient quantum of light it should face in the direction, where light is required.

• Only by getting properly mounted on heat radiating surface, these lights can pass their heat to the mounting surface and thus eliminate heat.

Now-a-days parabolic or different curved shaped lights are very aesthetic in nature and are greatly loved. Many different shapes are available in the market. However, with advent of LED lights, manufacturers have faced challenges to mount LED ships on curvaceous inner surface of Parabolic lights.

Almost all parabolic or curved shaped light manufacturers have resorted to using commercial LED bulb or other bulbs, which are placed inside the parabolic reflector using the simple bulb holder. Because mounting the LED lights/chips on the curvaceous surface is very complicated and by doing so, since the mounting angle of each lights/chips are different, direction of emission on light radiations from each lights/chip also becomes different. Due the this all the light radiations from all the lights are not confined to one single direction and thus the efficiency and intensity of light decreases.

In view of the above, it can be concluded that there is a long-felt need of a light assembly mechanism which enables the mounting of lighting means/chip on the horizontal flat surface while using it in the parabolic or curved shaped lights. There should be a mechanism to confine the light radiations of different light means in one single direction so that the efficiency and intensity of the light can be enhanced.
