The housing 14 is generally a rectangular housing 14 formed from a polymer (plastic) material. The housing 14 includes a front portion 14 a, a rear portion 14 b, a top portion 14 c, side portions 14 d and 14 e, and a bottom portion 14 f. Preferably the housing 14 is sized and configured to fit within an opening in the instrument panel IP or in another opening in the interior of a vehicle. Moreover, the housing 14 preferably contains the first electrical device 18, the second electrical device 20, the photosensor 22, the controller 26 and electrical circuitry, including contacts 28, to enable the electrical device 18 to be powered by a power supply PS. The rear portion 14 b of the housing 14 includes an opening 29 to enable a power supply PS to couple to the electrical device 18 (via the contacts 28) disposed in the housing 14. The rear portion 14 b of the housing 14 also includes an opening 31 to enable a power supply PS to couple to the electrical device 20 (via contacts 33) disposed in the housing 14. However, it is noted that the power supply PS can couple to only one contact or set of contacts to enable the power supply to power the first and second electrical devices 18 and 20. Additionally, the housing 14 can include coupling members (not shown) that enable the housing 14 to attach or couple to an interior portion of the vehicle. The housing 14 can contain any suitable devices or number of devices and is not limited to the components illustrated herein.
As shown in FIGS. 2 and 3, the faceplate 16 is attached to the housing 14, and has a first opening 30, a second opening 32, and a third opening 34. Preferably, the faceplate 16 is formed from a polymer (plastic) material similar to the housing 14, but can be formed from any suitable material. The first opening 30 is sized and configured to enable access to the electrical device 18 therethrough. In one embodiment, the first opening 30 is generally rectangular. The second opening 32 is generally sized and configured to enable at least a portion of the photosensor 22 to extend therethrough. In one embodiment, the second opening 32 is generally circular. The third opening 34 is generally sized and configured to enable access to a second electrical device 20 therethrough. In one embodiment, the second opening 34 is generally circular. Moreover, the faceplate 16 can have indicia thereon to indicate the type of electrical device 18 accessible through the faceplate 16.
The first electrical device 18 is generally rectangular and is at least partially disposed within the housing 14 so as to be accessible through the first opening 30. As shown in FIGS. 2 and 3, the electrical device 18 is preferably a Universal Serial Bus (USB) device configured to have an electrical connector or device inserted thereinto. The electrical device 18 can have an electrical contact (connection) 28 configured to receive electrical power from an electrical power supply PS. As illustrated in FIG. 4, the electrical connection 28 is disposed on the rear portion 12 b of the housing 14.
The second electrical device 20 is generally circular and is at least partially disposed within the housing 14 so as to be accessible through the third opening 34. As shown in FIGS. 2 and 3, the second electrical device 20 is preferably an auxiliary (AUX) jack. In other words, the second electrical device 20 can be an audio input jack for an audio device. The second electrical device 20 can have an electrical contact (connection) 33 configured to receive electrical power from an electrical power supply PS. As illustrated in FIG. 4, the electrical contact 33 is disposed on the rear portion 12 b of the housing 14. It is noted that the first and second electrical devices 18 and 20 can be any suitable devices. Moreover, there can be any suitable number or type of electrical devices, including but not limited to one, two or more devices. For example, the vehicle component 12 can include one or a plurality of USB devices, one or a plurality of SD card slots, one or a plurality of RCA connections, or any suitable type or combination of types of electrical devices or jacks.
The photosensor 22 is generally circular (or domed shaped) and is at least partially disposed within the housing 14 and within the second opening 32. The photosensor 22 extends at least partially out of the opening 32 so as to be capable of detecting ambient light from a plurality of directions. In one embodiment, the photosensor 22 is disposed generally in the central portion 16 a of the faceplate 16, but may be disposed in any suitable position near the lighting system 24. The photosensor 22 can be a photo electric sensor that contains optics and electrical circuitry, and can be powered by the same electrical power from the electrical power supply PS that powers the first and second electrical devices 18 and 20. Additionally, the photosensor 22 can be a photodiode, i.e., a semiconductor device that converts light into current. In other words, the photosensor 22 can be any device or structure configured to detect the ambient light level from an area adjacent the photosensor 22 and send a signal to a control device (controller 26) that enables the lighting system 24 to alter intensity based on the ambient light level.
The lighting system 24 is preferably LED lighting and is disposed around the periphery 16 b of the faceplate 16. As illustrated in FIG. 2, the lighting system 24 completely or substantially completely extends along the outer edge 40 of the faceplate 16 in a rectangular configuration to illuminate or light up the faceplate 16 and/or the entire area adjacent the faceplate 16. The lighting system 24 is configured to be activated or powered by the electrical power supply PS of the electrical device 18. Moreover, the intensity level of the lighting system 24 can be controlled by the photosensor 22. It is noted that the lighting system 24 can be any suitable lighting system 24 and disposed in a suitable position relative to the faceplate 16 and housing 14.
Accordingly, the lighting system 24 is capable of lighting the area near the electrical device 18 to enable a user to properly connect to the electrical device 18.
FIG. 5 illustrates one embodiment of an electrical circuit 42 for the vehicle component 12. In this embodiment, the circuit includes a battery or power source PS, a NPN bipolar junction transistor (voltage regulator) 44, a PNP bipolar junction transistor (voltage regulator) 46, diode 48, photosensor 22, the lighting system 24 (e.g., a LED) and resistors 50-60. The battery or power source PS can be the power source that operates the electrical device 18, such as the vehicle battery. When the ambient light level is below a predetermined amount (e.g., night) and at a first level of ambient light, the photosensor 22 is not activated (enters night mode), causing the current flow to travel from the bipolar junction transistor (voltage regulator) 44 through resistors 52 and 54 to the lighting system 24. The sum of resistors 52 and 54 limit the current through the lighting system 24 to establish a first predetermined brightness level (illumination level), or a low brightness level.
When the ambient light level is above the predetermined amount (e.g., day) and at a second level of ambient light, the-photosensor 22 is activated (enters day mode). That is, the photosensor is capable of determining that the ambient light level is above a predetermined amount. In this embodiment, the photosensor 22 is biased on, which in turn biases on the bipolar junction transistor 46. When the bipolar junction transistor 46 is biased on, the current flow is through the bipolar junction transistor 46 parallel to 52. Accordingly, the current bypasses resistor 52 and the resistance of resistor 52 is negated. So current flow is increased through the bipolar junction transistor 46 and resistor 54 through the lighting system 24 to establish a second predetermined brightness level (illumination level), or a high brightness level. Thus, the second predetermined brightness (day mode) is higher than the first predetermined brightness (night mode). In one embodiment, the first predetermined brightness and the second predetermined brightness are both “on” illumination levels. That is, both the first predetermined brightness and the second predetermined brightness are greater than zero. Moreover, in one embodiment, in day mode the brightness can be off if desired. Thus, in this embodiment, the second predetermined brightness (day mode) is lower (i.e., off) than the first predetermined brightness (night mode).
Accordingly, in one embodiment, the controller 26 can be a simple electrical circuitry that causes a change in current flow based on the ambient light determined by the photosensor. For example, in the circuit diagram illustrated in FIG. 5, the flow of electrical current is changed when photosensor 22 senses or determines a certain or predetermined level of light. Photosensor 22 is biased on, which in turn biases on bipolar junction transistor 46. These elements thus alter or change the flow of current to bypass the resistor 52.
Turning to FIG. 7, a method of providing two stage light or illumination to a vehicle component 12 is illustrated. In step S100 the method is started. Is step S110, an electrical device (e.g., electrical device 18) is powered using a power source PS. It is noted that multiple electrical devices can be powered using the power source or additional power sources. In step S120, a lighting system 24 is powered using the same power source as the electrical device 18. In the step S130 a photosensor detects or senses the ambient light of an area adjacent the electrical device 18. In S140, a determination is made of the level of the ambient light in the area adjacent the electrical device 18. In step S150, the level of ambient light is compared to a predetermined level. If the ambient is above the predetermined level, the lighting system 24 provides a first level of illumination in step S160. However, if the ambient is not above the predetermined level, the lighting system 24 provides a second level of illumination in step S160. The process can be repeated an a continuous basis to determine whether the illumination level needs to be altered or changed.
The first electrical device, the second electrical device and the photosensor can be conventional components that are well known in the art. Since these elements can be well known in the art, these structures will not be discussed or illustrated in further detail herein. Rather, it will be apparent to those skilled in the art from this disclosure that the components can be any type of structure and/or programming that can be used to carry out the present invention.
