The figures are for the purpose of illustration only and should not be construed as limitations on the assembly and mechanism of the present disclosure. Wherever possible, referral numerals will be used to refer to the same or like parts.
Figures 1 to 4 illustrate a self-illuminating light system for vehicles according to the present disclosure. The self-illuminating light system can be designed for a head light, taillight or any other alternative light of the vehicle. However, it is with in the purview of a person skilled in the art, that the self-illuminating light system can be re-designed for different vehicle makes.

As shown in figures 2, A light source (2) may be one or more Light emitting diode (LED)/bulb or any other suitable light source (2). An optical system (3) is mounted in between a lens (4) and a light source (2) reflects the light in different direction. The lens (4) is positioned in front of optical system (3) to scatter the light in different direction. The lens (4), optical system (3) and light source (2) are assembled together to form an automotive lamp (1). Alternatively, the automotive lamp (1) may also be formed from the lens (4) and light source (2) i.e. without the optical system (3). The LED bulb is coupled with a printed circuit board (PCB) (5). The PCB (5) is disposed at the rear end of the automotive lamp (1), along with the LED bulb (2). The LED bulb (2) is powered by the battery of the vehicle through the PCB (5). The optical system (3) is mounted in a position whereby the light from the LED bulb (2) reflects towards the lens (4).
In an embodiment of the present disclosure, the lens (4) illuminates with or without receiving electricity/power. When a light from the light source or sunlight incident on the lens (4), the lens (4) absorbs said light. Subsequently, the lens (4) emits absorbed light when no light from the light source (i.e. in dark or night). The light source (2) can be Sunlight, LED Bulb of automotive lamp, light of other vehicles or pole light on the road.
In an embodiment, the lens (4) is made from a GID material. The GID material is a blend of Polycarbonate (PC), Poly Methyl Methacrylate (PMMA), a coloring agent and a photoluminescent material. Alternatively, either Polycarbonate (PC) or Poly Methyl Methacrylate (PMMA) may be mixed with the coloring agent and the photoluminescent material to prepare the blend. The constituents of the blend are mixed in such a pre-defined proportion that the lens (4) made of such material provide uniform illuminance even without electricity/power. The lens (4) is manufactured by injection molding process. The lens (4) made of GID material may have physical appearance of white color, same, as the conventional lens in daytime Lamp OFF condition and in Lamp ON condition.
As shown in figure 2, when a battery of the vehicle is in 'ON' condition, the LED bulb (2) illuminate the optical region by receiving electricity/power from battery. The optical system

(3) scatters and/or direct the light towards the lens (4). The light incident on the lens (4) and the lens (4) absorbs the said light.
As shown in figure 3, when the battery of the vehicle is in 'OFF' condition, the lens (4) emits the absorbed light in the absence of light (i.e. in dark). The lens (4) is capable to illuminate in different colors such as red, green, blue, amber or any alternate colors by varying the formulation of GID material.
Referring to table 1, the Inventor of the present disclosure has performed several experiments on the self-illuminating light system to find the glow intensity of the light in respect of glow time of the lens thereof. For experiments, four lens have been taken in which each lens has different GID material and each GID material has different color. There are four colors Green, Blue, Red and Amber have been used individually in four GID materials. The intensity of light has been noted of each color after 10 minutes and 60 minutes from the time, when the lens started to glow. Through experiments, it has been observed that the intensity of light corresponds to the glow time of every colors is different from one another.
