Abstract
A replaceable LED system adapted to selectively transform the unidirectional glow of the LEDs / LED chips and/or any other semiconductor light emitting device into a more uniform glow for better visual appeal along with providing the system as a shock, vibration resistant and unbreakable unit for wide scale and safe application and use. The LED system of the invention avoids the inherent limitation of LEDs in generating unidirectional glow / illumination and favours a comfortable wider uniform visual glow / illumination from LEDs even in directions other than the direction of installation of the LED. The LED system is suitable for use in domestic applications such as general lighting, decorative lamp, night lamp etc. apart from wide scale applications as indicator systems in industrial and automotive application such as impact resistant and unbreakable front and rear indicator lights in vehicles, signal lights in railways, road traffic and aviation lights and like.
