## Background
FIELD OF THE INVENTION
The present invention relates generally to vehicle lighting systems, more specifically but not by way of limitation, a lighting assembly operable to be placed in the headlight of a vehicle wherein the lighting assembly produces a first color and a second color and wherein the lighting assembly is operable to detect environmental conditions such as but not limited to ambient light and fog.
BACKGROUND
Vehicles such as automobiles and trucks are required to have certain lights and lighting systems in order to be compliant with safety regulations. A conventional lighting system will include turn indicator lights, brake lights and headlights. All of these are required in order to operate a vehicle on public roads. The headlights of a vehicle are utilized during night and low light conditions and provide visibility of the area immediately in front of the vehicle for the driver. Conventional headlights illuminate several hundred feet in front of the vehicle and are further utilized to provide visual signals to approaching vehicle allowing drivers to operate safely.
One problem with conventional headlights is the generation of only one light wavelength. Most headlights generate a single wavelength spectrum such as but not limited to white. The white light is a mixture of the colors of the visible light spectrum and cannot be seen in daylight conditions from as far away when compared to a single light wave that is at the higher end of the range of visible light spectrum.
Another issue with conventional headlights is their inability to react to and change operational modes based on environmental conditions. Drivers will typically encounter adverse driving conditions such as but not limited to fog. Conventional vehicle lighting systems do not provide any measurement of the fog nor any subsequent operation of the headlight once adverse driving conditions have been detected.
Accordingly, there is a need for a headlight lighting assembly that can be operably coupled to a headlight of a vehicle wherein the headlight lighting assembly is operable to provide a first mode and second mode of operation during ambient light conditions and night time conditions and wherein the headlight assembly is further operable to detect adverse conditions such as but not limited to fog and provide activation of a light of the headlight lighting assembly.
SUMMARY OF THE INVENTION
It is the object of the present invention to provide a vehicle headlight lighting assembly that includes a first bulb and a second bulb that are operational in a first mode and second mode dependent upon the environmental conditions.
Another object of the present invention is to provide a vehicle headlight lighting assembly having a first operational mode and a second operational mode wherein in the first operational mode the headlight lighting assembly is operable to operate a first bulb that produces a first color.
An alternative object of the present invention is to provide a vehicle headlight lighting assembly having a first operational mode and a second operational mode wherein in the second operational mode the headlight lighting assembly is operable to illuminate a second bulb that produces a second color.
A further object of the present invention is to provide a vehicle headlight lighting assembly having a first and second operational mode that further includes a transmitter and a receive in a base plug that is operable to detect adverse driving conditions such as but not limited to fog.
An added object of the present invention is to provide a vehicle headlight lighting assembly having a first and second operational mode that further includes a photo sensor on the base plug wherein the photo sensor is operable to activate the second operational mode subsequent to detection of sufficient ambient light.
Still a further object of the present invention is to provide a vehicle headlight lighting assembly having a first bulb and a second bulb wherein the second color produced by the second bulb is amber.
An additional object of the present invention is to provide a vehicle headlight lighting system having a first operational mode and a second operational mode wherein the transmitter in the base plug is operable to produce a light beam and wherein the transmitter is angled away from the receiver in the base plug.
Yet another object of the present invention is to provide a vehicle headlight lighting assembly having a first operational mode and a second operational mode that includes a central processing unit having the necessary electronics to store, receive, transmit and process the data required to operate the headlight lighting assembly.
To the accomplishment of the above and related objects the present invention may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact that the drawings are illustrative only. Variations are contemplated as being a part of the present invention, limited only by the scope of the claims.

FIG. 1 is a diagrammatic view of the present invention; and
FIG. 2 is a diagrammatic view of the present invention placed in a conventional headlight cavity.



DETAILED DESCRIPTION
Referring now to the drawings submitted herewith, wherein various elements depicted therein are not necessarily drawn to scale and wherein through the views and figures like elements are referenced with identical reference numerals, there is illustrated a headlight lighting assembly 100 constructed according to the principles of the present invention.
Referring in particular to FIG. 1 herein, the headlight lighting assembly 100 includes a harness plug 10 that is operably coupled to an electrical system 99 of a vehicle using wire 5. Harness plug 10 includes female sockets 11, 12 that are operable to electrically couple with the male prongs 23,24 of the base plug 20. The harness plug 10 includes body 9 that is manufactured from a suitable durable material such as but not limited to plastic. The body 9 of the harness plug 10 includes an interior cavity (not illustrated herein) that is suitable in size so as to accommodate the central processing unit 30. The central processing unit 30 is secured within the interior cavity of the body 9 utilizing suitable durable techniques. The central processing unit 30 contains the necessary electronics to store, receive, transmit and manipulate data in order to facilitate the operation of the headlight lighting assembly 100. While in the preferred embodiment, the central processing unit 30 is mounted within the harness plug 10 so as to provide retrofit capabilities for the headlight lighting assembly 100, it is contemplated within the scope of the present invention that the central processing unit 30 could be included and/or mounted to another component of a vehicles electrical system.
The headlight lighting assembly 100 further includes a base plug 20. The base plug 20 is configured to operably couple to the harness plug 10. In the preferred embodiment illustrated herein the base plug 20 includes male prongs 23, 24 that are configured to be inserted into female sockets 11, 12. While the aforementioned technique and elements for coupling the base plug 20 to the harness plug 10 is illustrated and described for the preferred embodiment, it is contemplated within the scope of the present invention that the base plug 20 and harness plug 10 could be configured to operably couple using numerous suitable techniques. The base plug 20 includes body 25 that is square in shape being manufactured from a suitable durable material such as but not limited to plastic. The base plug 20 includes a first side 26 and a second side 27. Secured to the first side 26 and second side 27 are the receiver 40 and transmitter 50 of the fog sensor 55. The fog sensor 55 is operably coupled to the central processing unit 30 and is operable to illuminate the first bulb 80 subsequent detection of fog or moisture in the atmosphere in front of the vehicle in which the headlight lighting assembly 100 is installed. The transmitter 50 of the fog sensor 55 projects a light beam (of a non-visible spectrum) outward from the headlight assembly 1. The transmitter 50 is mounted within the base plug 20 such that it is angular in manner with respect to the receiver 40. The angled orientation of the transmitter 50 ensures that the light beam emitted therefrom is only detected when fog or smoke particles are in the air in front of the vehicle and the scattered reflection therefrom is then detected by the receiver 40. The angular mounting of the transmitter 50 is required in to prevent the activation of the first bulb 80 during normal driving conditions where no fog or smoke is present.
The fog sensor 55 is operably coupled to the central processing unit 30 and controls the first mode of operation of the headlight lighting assembly 100. In the first mode of operation, as a vehicle having the headlight lighting assembly travels in a forward direction the transmitter 50 continuously emits a non-visible light beam in the direction that the vehicle is traveling. In the presence of particles such as but not limited to fog or smoke, that could present adverse driving conditions, the light beam from the transmitter 50 is scatter and some of the light beam is reflected back and detected by the receiver 40. Subsequent the receiver 40 detecting light particles from the transmitter 50, a signal is transmitted to the central processing unit 30 wherein the central processing unit 30 illuminates the first bulb 80. The first bulb 80 is a conventional light bulb such as but not limited to an LED bulb and is configured to emit a first color. While no particular color is required, good results have been achieved utilizing a first bulb 80 that emits a white color spectrum. The headlight lighting assembly 100 continues to illuminate the first bulb 80 as the receiver 40 continues to detect at least a portion of the light beam being emitted from the transmitter 50.
The base plug 20 further includes a photo sensor 70. The photo sensor 70 is secured to the base plug 20 utilizing suitable durable techniques. The photo sensor 70 is mounted at the forward edge 28 of the base plug and is operable to detect the presence of ambient light so as to control the second mode of operation of the headlight lighting assembly 100. The photo sensor 70 is a conventional photo sensor and is operable to detect visible light spectrums and can utilize a photodiode, phototransistor or other suitable element to detect the visible light spectrum. The photo sensor 70 will transmit a signal to the central processing unit 70 subsequent the detection of visible light, in this case daylight, and the central processing unit 30 will then illuminate the second bulb 90. The second bulb 90 is operable to increase the visibility of the vehicle in which the headlight lighting assembly 100 is mounted. The second bulb 90 is configured to emit a longer wavelength visible light such as but not limited to amber. It is desired within the scope of the present invention that the second bulb 90 is configured to emit a light wavelength that is within the range of 580 nm to 600 nm. The aforementioned wavelength provides greater visibility than shorter wavelengths and is operable to assist in the improved visibility of the vehicle in which the headlight lighting assembly 100 is mounted. While a particular wavelength has been described herein for the second bulb 90, it should be recognized that the second bulb 90 could be configured to emit various different wavelengths in order to accomplish the desired functionality described herein.
The photo sensor 70 is further operable to control the third mode of operation of the headlight lighting assembly 100. In the third mode of operation, the photo sensor 70 detects the absence of ambient light, nighttime, and transmits a signal to the central processing unit 30 wherein the central processing unit 30 will then illuminate the first bulb 80 providing the necessary lighting for a vehicle to operate safely at night.
Photo sensor 70 is additionally operable to control a fourth mode of operation for the headlight lighting assembly 100. In the fourth mode of operation of the headlight lighting assembly 100, the photo sensor is programmed by the central processing unit 30 to detect high beam illumination from an oncoming vehicle. Subsequent detection of high beam illumination from an oncoming vehicle, the photo sensor 70 will transmit a signal to the central processing unit 30 wherein the central processing unit 30 will perform the necessary steps to illuminate either the first bulb 80 and/or the second bulb 90 wherein the first bulb 80 and/or the second bulb 90 is illuminated in a rapid blinking pattern for at least two seconds. The illumination blinking pattern functions to provide notification to the oncoming vehicle to eliminate their high beam illumination. Subsequent the blinking pattern illumination of either the first bulb 80 and/or the second bulb 90 the photo sensor 70 will continue to monitor for the presence of the high beam illumination from an oncoming vehicle. Once the high beam illumination is no longer detected, the headlight lighting assembly 100 resumes operation as described herein. If continued detection of high beam illumination is detected from an oncoming vehicle then the central processing unit 30 will initiate the blinking sequence at least once more and if subsequent detection continues then the central processing unit 30 will increase the illumination intensity of either the first bulb 80 and/or the second bulb 90.
The first bulb 80 and second bulb 90 are secured to the bulb base 110. The bulb base 110 includes male prongs 111,112 that are operable to couple with female sockets (not illustrated herein) integrally formed in the base plug 20. The aforementioned coupling technique provides the electrical and operational connection required to facilitate the functionality described herein. While the male prongs 111, 112 are illustrated and described herein as the preferred technique for operably coupling the bulb base 110 to the base plug 20, it is contemplated within the scope of the present invention that numerous techniques could be utilized to operably couple the bulb base 110 to the base plug 20. The first bulb 80 and second bulb 90 are releasably secured to the bulb base 110 so as to facilitate the replacement thereof in the event of a failure.
The headlight lighting assembly 100 in its preferred embodiment is configured to replacement conventional headlight bulbs with the ability to be retrofit into numerous makes and models of vehicles.
