Description

L1GHT ENCLOSURE FOR TRACTOR/TRAILER INCORPORATING ANTENNA AND/OR RADIO COMPONENTS
BACKGROUND OF THE INVENTION
For many businesses, it is increasingly important to trace mobile assets and the carriers of mobile assets. Hundreds of thousands of dollars worth of goods, such as computers, can be carried by mobile vehicles, such as tractor trailers for example. Generally, the owners of the mobile vehicles are responsible for delivery of the mobile goods. Cellular telephone technology is usually used to track the mobile goods by the owner. Global positioning system (GPS) technology can also be used to track the goods. However, tracking goods using either technology can be cumbersome because of the need for a separate cellular phone and GPS antenna mounted to the carrier vehicle. The cellular phone and GPS antennae would protrude from the carrier vehicles which would be impractical. When the carrier vehicle trailers are stacked on ships for overseas shipment, the protruding cellular phone and GPS antennae may be damaged. Installation time for separate antennas is time consuming and results in holes to the trailer body which have to be sealed.
The protruding antennae can also be impractical from a security standpoint. Protruding antennae would not be conspicuous and could alert thieves to the existence of mobile assets on a carrier vehicle. Conspicuous placement of antenna would prevent thieves from removing the antenna. Also, owners might want to prevent the fact that the vehicle could be tracked from becoming publically known.
The prior art discloses a GPS antenna mounted within a brake light, published in Research Disclosure, November 1998. As disclosed, mounting the GPS antenna within a brake light housing can help prevent damage or theft to the antenna. SUMMARY OF THE INVENTION
The present invention relates to an integrated unit to hold two types of antenna, a GPS antenna and a communications antenna, such as a cellular phone antenna. The invention integrates the two antenna as part of a marker light. The present invention improves upon the prior art by including both a GPS antenna and a communications antenna within a common housing. Inclusion of both types of antenna within a housing improves over the prior art by providing a single unit that allows for reception of various types of communications signals, rather than just a GPS signal. The present invention also improves over the prior art by the inclusion of an infrared port within the housing. The port can allow wireless communications with an external device for the purpose of a diagnostic check of the invention, for example.
In one embodiment, the invention is a marker light having a lens housing, a global positioning system antenna mounted within the housing, a communications antenna mounted within the housing and a lighting device mounted within the housing. The marker light can include a circuit board, mounted within the lens housing, connected to the lighting device. The lens housing of the marker light can be made from a plastic material and can also be made from a light reflective material. The lens housing can have a front portion and a back portion and, one embodiment, the front portion and the back portion are sealed together to form a watertight unit.
The lens housing of the marker light can have a plurality of support structures which can include a global positioning system antenna support structure, a circuit board support structure and a communications antenna support structure. The communications antenna can include a coaxial cable or a cellular telephone antenna. In this embodiment, the lighting device has at least one light emitting diode.
In an alternate embodiment, the invention is a marker light having a lens housing, a global positioning system antenna mounted within the housing, a communications antenna mounted within the housing and a circuit board having an infrared port to provide communications between the circuit board and an external device and having at least one light emitting diode. The lens housing of the marker light can be made from a plastic material and can also be made from a light reflective material. The lens housing can have a front portion and a back portion and, one embodiment, the front portion and the back portion are sealed together to form a watertight unit.
The lens housing of the marker light can have a plurality of support structures which can include a global positioning system antenna support structure, a circuit board support structure and a communications antenna support structure.
