The present disclosure, in general, relates to a spotlight that is used to produce intense illumination in a well-defined area in stage, film, television, ballet, opera production, and as per consumer requirements. The spotlight resembles a small searchlight but usually has shutters, an iris diaphragm, and adjustable lenses to shape the projected light. In particular, the present disclosure relates to a spotlight having screwless structure with high efficiency, cost-effective,easy to assemble, and easy to mass produce to meet large market requirements.
BACKGROUND
[0002] Currently, there are a lot of interest in using high brightness white Light Emitting Diodes(LEDs) to replace conventional incandescent light bulbs, halogen reflector spotlights and fluorescent spotlights. Most lighting devices utilizing high brightness white LEDs comprise arrangements in which a plurality of LEDs replaces the conventional light source component and utilize the existing optical components such as a reflector and/or a lens. Ideally a spotlight would generate an illuminance (luminous flux (power) per unit area incident on a surface) that was substantially uniform across the spotlight's emission angle (beam spread).
[0003] In other words, LEDs are increasingly being utilized as a light source in various lighting fixtures because of their inherently high efficiency in converting electrical power to light. Although LED elements are relatively expensive, compared to incandescent, and other forms of light sources, the initial cost is recovered over time through energy conversion efficiencies. A typical LED light source suitable for commercial and theatrical lighting can be

comprised of a plurality of individual LED elements arranged in an enclosed housing to discharge light through an output lens or window of a predetermined size and shape.
[0004] There is always a frequent requirement of commercial and theatrical lighting is to be able to confine light output of a luminaire or light fixture to a relatively narrow beam, so that a particular object can be highlighted in relation to its immediate surroundings. With available commercial LED illumination modules, the light output lens or window covers a plurality of LED elements and accordingly is of relatively large diameter. The emitted light is somewhat diffused in that it originates from a plurality of sources and confinement of the light into a tight beam requires reflectors, typically of a compound parabolic configuration, to be undesirably long in an axial direction.
[0005] In addition, most of the spot light used in market with main body completely made up of plastic & have input wire come from center area, which cause problem during spotlight mounting on small height junction box.
[0006] Moreover, due to LED heat, live wire need isolation from heat area, but most of the LED spotlights available in market has direct contact with heat area, which may give rigidity in wire to decay & get wasted quickly. Furthermore, a metal clip (for mounting of the spotlight) attached with the spotlight has provision of screw, which results in over costing and also have provision of external driver, which makes spotlight bigger in size.
[0007] Hence, there is a need of the spotlight having screwless structure, highly efficient, cost-effective in nature, easy to assemble, and easy to mass produce to meet large market requirements.

[0008] Some of the objects of the present disclosure, which at least one embodiment herein satisfy, are listed hereinbelow.

[0009] It is a general or primary object of the present disclosure to provide a spotlight having very strong emitting points so that light attenuation is much lower than the existing spotlights.
