DESC:FIELD OF THE INVENTION:
The present invention relates to an improved vehicle headlight module for dissipating concentrated rays and a method thereof. The present invention specifically relates to the vehicle headlight module to dissipate concentrated sunrays.
BACKGROUND OF THE INVENTION:
In state-of-the-art, automobiles are equipped with headlamps/headlights whose function is to provide light to the vehicle driver in order to ensure proper visibility of the object/s lying on the road. Further, these headlights hold significant importance in various situations such as during foggy weather, daylight, night-time, and so on, to ensure and provide proper and adequate visibility for the vehicle driver, thereby avoiding collision of the vehicles.
In the state of the art, a typical headlight comprises the following optical elements:
a) A lens having an outer surface and an inner surface;
b) An inner reflector having a plane surface that helps the light to reflect back to the inner and outer surface of the lens to achieve maximum illumination.
In general, the lens in the typical headlight has a convex curvature on the outer surface and a concave curvature on the inner surface. Further, the inner reflector comprises a plane reflector that reflects light back to the inner and outer surface of the lens, which is exploited to increase the illumination of the light beam from the headlight. While this feature is useful during night-time but during day time, it creates a technical issue of forming hotspot due to incoming sun rays. The incoming sun rays are incident onto convex curvature of the lens and are then transmitted to concave curvature of the lens. These transmitted sunrays are then directed toward the plane surface of the inner reflector. The inner reflector reflects these sun rays on inner and outer surface of the lens respectively. Further, these reflected sunrays are falling at one common point of inner and outer surface of the lens. Due to this, there is a formation of concentrated sunrays on the lens and thereby a formation of hot spots.
Further, the additional associated technical problems related to the typical headlight are as follows:
- formation of hot spots leads to the phenomenon of causing thermal effects inside and outside the vehicle;
- thermal effects give rise to an increase in temperature within the vehicle body and in front of the headlight and thereby causes melting of the fascia/dashboard (made up of plastic) that is present in the vehicle;
- thermal effects leading to the bursting of LEDs present inside the headlight module and thereby requiring a repetitive change in the LEDs;
- thermal effects leading to decreased fuel efficiency since the vehicle interior is required to maintain at a temperature that the passengers can bear;
- thermal effects leading to long usage of vehicle air-conditioners and thereby an increase in the release of toxic pollutants in the atmosphere. Thus, leading to an increase in air pollution;
- thermal effects cause a rise in the temperature of the vehicle body which may lead to short-circuiting in the electrical wires and thereby vehicle may catch fire. Thus, damaging the vehicle as whole.
Following are the prior arts that deal with headlight modules having optical elements for diffusing concentrated sunrays from the vehicle:
DE102013214990A1 discloses and teaches about a headlight that has a metal coating on the lens holder wherein the metal coating has a thickness and provides a wider area for distributing and dissipating sunlight. Further, DE990 also discloses a projection module which includes a light source for emitting light and a projection lens hold on the lens holder. The projection lens has a curved surface at one of its sides on which sunlight is incident. Further, the lens holder has at least partially on a side facing an optical axis of the projection module side applied to the lens holder metal coating. Further, in order to prevent damage or deformation of the lens holder due to solar radiation, a metal coating applied to the lens holder on a side directed toward an optical axis of the projection module. The metal coating is preferably applied to the plastic material of the lens holder during the manufacturing process of the lens holder. So, when sun rays enter the light module through the projection lens and they are focused in the area of the lens holder, the locally generated heat is dissipated by the metal coating and distributed over a larger area. Over the large surface of the metal coating, the heat can be released particularly well to the environment. The thickness and size of the metal layer are chosen so that sufficient heat dissipation can be ensured even with particularly strong sunlight.

DESCRIPTION
Fig. 1 relates to a typical headlight/headlamp (100) that comprises an outer lens having an outer surface which has a convex curvature (101), and an inner surface which has a concave curvature (102), an inner reflector having a plane surface (103). The inner optical element (103) having curvature surface helps the light to reflect from and direct it towards the outer surface lens to achieve maximum illumination.
The incoming direct sunrays fall onto convex curvature (101) of the lens which is further transmitted to concave curvature (102) of the lens. The transmitted sunrays are directed towards the inner optical surface (103) of the inner optical element. The reflected sunrays from the plane surface of the inner optical element (103) are re-transmitted back to inner surface of the lens (102). Further, these rays are then directed to the outer surface of the lens (101).
Since the inner reflector has an inner optical curvature surface, transmitted sunrays from inner surface of lens (102) fall onto one particular region of inner optical element (103). Due to this, the re-transmitted sunrays from the inner reflector to inner and outer surface of the lens (102 & 101) are thereby concentrating at one common/particular point (104). Thereby, there is a formation of concentrated sunrays in a typical headlight along with the formation of hot spots. The concentrated sunrays on the typical headlight are associated with the following short-comings:
- generating thermal effects that give rise to an increase in temperature within the vehicle body and in front of the headlight/headlamp and thereby causing melting of the fascia/dashboard (made up of plastic) that is present inside the vehicle;
- thermal effects leading to the bursting of LEDs present inside the headlight module and thereby requiring a repetitive change in the LEDs;
- thermal effects leading to decreased fuel efficiency, since the vehicle interior is required to maintain at temperature that passengers can bear comfortably;
- thermal effects leading to long usage of vehicle air-conditioners and thereby an increase in the release of toxic pollutants in the atmosphere. Thus, leading to an increase in air pollution;
- thermal effects cause a rise in the temperature of the vehicle body which may lead to short-circuiting in the electrical wires and thereby vehicle may catch fire. Thus, damaging the vehicle as a whole
These technical issues need a technical solution that is capable of resolving these shortcomings of conventional headlamp assembly in a cheaper and an efficient manner.
The present invention relates to an improved compact vehicle headlight/headlamp module for dissipating concentrated sunrays.
Further, the present invention relates to a compact headlamp module that has optical elements with curvature to it, thereby providing a larger surface area for dissipating concentrated/focused sunrays.
The compact vehicle headlamp module comprises of:
• a plurality of lens, while the lens has an outer surface having a convex curvature and an inner surface having a concave curvature; and
• a plurality of inner optical element, which includes an inner optical surface and has angular curvature that forms a cavity in it for dissipating concentrated sunrays.
Further, the compact vehicle headlamp module uniformly, homogeneously, and efficiently dissipates concentrated sunrays and eliminates hot-spot formation.
The compact vehicle headlamp module is comprised of a lens and an optical elements that are designed and implemented in a unique way for dissipating concentrated sunrays from the vehicle. The compact vehicle headlight module has lens whose outer surface has convex curvature and inner surface has a concave curvature. Further, inner optical surface of inner optical element is capable to form cavity in the headlamp module which will help to dissipate concentrated sun rays.
The incoming sunrays first fall onto convex curvature of the lens and are transmitted to concave curvature of the lens thereof. Further, the transmitted sunrays fall onto curvature of the inner optical surface of inner optical element and form reflected sun rays. During this, each of the transmitted sunrays falls onto different regions of angular curvature of inner optical surface of inner optical element. The reflected sunrays are re-transmitted back to concave curvature and to convex curvature of the lens respectively. The reflected sunrays are falling onto different regions of inner and outer surface of the lens because of which there is an elimination of formation of concentrated sunrays on compact vehicle headlight module as whole.
Fig. 2(a) illustrates the compact vehicle headlamp module (200) of the present invention. Figure 2(b) illustrates exploded view of inner optical surface of inner optical element of the compact vehicle headlamp module forming a cavity in accordance with embodiment of present invention. Figure 2(c) illustrates sectional view of inner optical surface of inner optical element of the compact vehicle headlamp module in accordance with present invention.
The compact vehicle headlight module (200) comprises of a lens (201) and an inner optical element (202). The lens (201) has an outer surface that forms a convex curvature (201a) and an inner surface that forms a concave curvature (201b). In furtherance of this, there is a pre-determined distance between concave curvature of the lens (201b) and angular curvature of the inner optical element (202) because of which there is an adequate reflection and thereby a formation of reflected sunrays. The range of the pre-determined distance between concave curvature of the lens (201b) and angular curvature of the inner optical element (202) is between 1-50 mm.

The inner optical element of present invention forms a cavity (203) because of presence of angular curvature (202) in it. The inner optical element has inner optical surface having curvature wherein the rays are reflected due to physical law called Fressnel reflection. The radius of the inner optical element (202) may vary and will depend on the requirement of the user to prepare the compact vehicle headlight module is in the range of 2-1000 mm.

The lens (201) is made up of glass and is transparent in nature. Alternatively, the material of the lens may vary wherein the material needs to be of the type that offers transparency. Further, the material of the inner reflector is glass which is transparent in nature. In an alternate embodiment, the material of the inner reflector is not limited to glass and may include material that has the feature of being transparent.
The incoming radiated sunrays fall onto convex curvature of lens (201a) and are then transmitted to concave curvature of lens (201b). The transmitted sunrays are directed toward different regions of angular curvature of inner optical element (202). Further, transmitted sunrays are distributed to large surface area using presence of angular curvature of inner optical element (202) having curvature. The transmitted sunrays provide formation of reflected sunrays by using inner optical element (202). The reflected sunrays from angular curvature of inner optical element having inner optical surface (202) are re-transmitted back towards different regions of inner surface of the lens (201b). Further, these rays are re-directed toward different regions of outer surface of the lens (201a) and form a resultant light beam from the compact vehicle headlamp module (200). Since, there is not a single phenomenon of the formation of concentrated sunrays in the present invention, thus, there is an adequate elimination of the formation of hot spots.
Additionally, the present invention is adequate for usage in any vehicle as a headlamp or headlight. It can be further used in areas where there is a formation of concentrated sunrays such as glasses equipped in buildings, decorative glass materials equipped in the entrance gate of houses, and so on.
The present invention relates to a method of dissipating the sunrays from the improved compact vehicle headlamp module (300), wherein the method includes the following steps:
At step (301), an incoming radiated sunrays are falling onto different regions of outer surface of the lens (201a). This feature is provided by outer surface of the lens because there is a presence of convex curvature (201a). Due to this, there is provided a larger surface area for the incoming radiated sunrays.
Then, at step (302), the sunrays are transmitted towards different regions of inner surface of lens (201b). This is ensured because of presence of concave curvature of the lens (201b) in the compact vehicle headlamp module (200);
Then, at step (303), the transmitted sunrays are falling onto different regions of angular curvature of inner optical surface of inner optical element (202). This implies that angular-curvature of inner optical surface of inner optical element (202) provides a larger surface area for the transmitted sunrays that are falling onto it from concave curvature of the lens (201b);
Next, at step (304), the reflected sunrays from angular curvature of inner optical surface of inner optical element (202) fall onto different regions of inner surface of lens (201b). This is because, there is no formation of concentrated sunrays during transmission of the sunrays from the concave curvature of lens (201b) to the curvature of the inner optical surface of inner optical element(202).
Thereby, at step (305), the reflected sunrays from inner surface (201b) are re-transmitted onto different regions of outer surface of lens (201a) which causes sunrays to dissipate from the compact vehicle headlamp module (200). Further, outer surface of the lens (201a) provides wider surface area for uniform, homogeneous and efficient dissipation of sunrays. Hence, eliminating any chance of formation of hot spot onto a vehicle.

The radius/ curvature of outer surface of lens 1-50 mm
The radius/ curvature of inner surface of lens 1-50 mm
The radius of the inner optical element 1-50 mm

The compact vehicle headlamp module of the present invention leads to the following technical advantages:
- a larger surface area is provided as a whole because of which there is a dissipation of the concentrated sunrays;
- due to dissipation of concentrated sunrays, thermal effects are eliminated in the compact vehicle headlamp;
- elimination of thermal effects ensures elimination of formation of hot-spots in the compact vehicle headlight module as a whole;
- elimination of thermal effects caused by concentrated sunrays implies elimination of rise in temperature inside the vehicle and thus providing safety to components that are present inside vehicle such as seat covers, fascia, and so on;
- due to elimination of thermal effect, there is less rise in temperature inside of the vehicle, so, there will be less usage of air-conditioner and thus saving of battery;
- lesser the use of air-conditioner, lesser is the generation of air-pollutants from vehicle and thereby causing reduction in air pollution from vehicle;
- due to saving of battery, there is an advantage of ensuring higher fuel efficiency; and
- uniformly, homogeneously, and efficiently dissipating sunrays
