DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
(17)
(18) Light strip assemblies 20 and 50 are substantially identical and thus the detailed descriptions which follow for light strip assembly 20 will be understood to apply with equal force and effect to light strip assembly 50. The important aspect with respect to the present invention is the advantage found in the ability of the present invention traffic control light strips to be serially connected and thereby increase the traffic control light strip overall length to meet the needs of a given accident scene. It will also be noted that in the example shown in
(19) With particular reference to light strip assembly 20, a plurality of light strip segments 21 through 28 are serially joined by a corresponding plurality of cooperating connector pairs 31 through 37. The structure of connector pairs 31 through 37 is set forth below in greater detail. Suffice it to note here that connector pairs 31 through 37 provide mechanical attachment between adjacent light strip segments together with appropriate electrical connections therebetween. Connectors 30 and 38 facilitate connection of light strip assembly 20 to other light strip assemblies in a manner that allows the action of the LED units to be synchronized. Each of light strip segments 21 through 28 supports an LED unit 41 through 48 respectively. For purposes of the example shown herein, each LED unit will be understood to support a single high power light emitting diode. Once again, it will be apparent to those skilled in the art that a variety of light emitting diode configurations may be utilized within LED units 41 through 48 without departing from the spirit and scope of the present invention. For example, each LED unit may support a light emitting diode which emits light of a selected color, white light or infrared light to suit particular needs. By way of further alternative, pluralities of light emitting diodes, having different color, or brightness outputs, may be supported within each of the LED units to provide alternative color effects.
(20) In the preferred fabrication of the present invention, light strip assembly 20 utilizes light strip segments 21 through 28 with each segment being approximately three feet in length. In further accordance with the preferred fabrication of the present invention traffic control light strip, eight three foot segments are combined to provide an overall length of approximately twenty-four feet for light strip assembly 20. Once again, it will be understood that, while this arrangement has been found to be advantageous, the present invention is not limited to any particular light strip segment length or number of light strip segments joined to form the inventive light strip assembly.
(21) As mentioned above, light strip assembly 50 will be understood to be substantially identical to light strip assembly 20. In accordance with an important aspect of the present invention light strip assembly 20 includes a connector 38 while light strip assembly 50 includes a cooperating connector 61. Accordingly, the serial combination of light strip assembly 20 and light strip assembly 50 is accomplished by the connection provided by cooperating connectors 38 and 61.
(22) A power and control unit 29 is attached to one end of light strip assembly 20 in the manner set forth below in greater detail. Suffice it to note here that the attachment of power and control unit 29 to the end of light strip assembly 20 provides electrical connection between the operative circuitry within power and control unit 29 and the electrical circuit within light strip segments 21 through 28. It will be recalled that connector pairs 31 through 37 provide electrical connections between their respective light strip segments. Similarly the connection provided by connectors 38 and 61 further couples control circuit 29 to control circuit 39 of light strip assembly 50. In this manner, a single control unit is able to control all of the light emitting diodes within light strip assemblies 20 and 50.
(23) Once light strip assemblies 20 and 50 have been deployed and joined serially in the manner shown in
(24)
(25) By way of overview, and as is mentioned, above, light strip assembly 20 includes light strip segments fabricated as three basic segment types. Light strip segments (such as segment 21) of the first segment type support an LED unit and are constructed to provide one connector able to make a synchronizing signal and mechanical connection to another light strip assembly together with a second connector for power and control connection to another light strip segment. The second type of light strip segments (segments 22 through 27) support an LED unit together with connectors at each end suitable for power and control coupling to another light strip segment. The third type of light strip segment (segment 28) supports an LED unit and one connector at one and for power and control connection to another light strip segment and one connector at the remaining end configured to make a control signal connection and mechanical attachment to another light strip assembly.
(26) More specifically, light strip segment 21 (which is configured as a first type) includes a connector plug 91 at one end thereof and a connector receptacle 81 at its opposite end. Light strip segment 21 further supports an LED unit 41. For purposes of illustration, LED unit 41 is shown near the midpoint of light strip segment 21. However it will be apparent to those skilled in the art that the position of LED unit 41 is a matter of design choice and the centered position of LED unit 41 shown in
(27) Light strip segments 22 through 27 are light strip segments of the second type and are substantially identical to each other. Accordingly, light strip segment 22 supports an LED unit 42 together with a connector plug 92 and a connector receptacle 82 at opposed ends thereof. Similarly, light strip segments 23 through 27 support respective LED units 43 through 47 together with respective connector plugs 93 through 97 and respective connector receptacles 83 through 87. Lights strip segment 28 is a segment of the third type having a connector 98 suitable for power and control coupling to another strip segments such as segment 27 and a connector 88 suitable for providing control signal coupling to another light strip assembly.
(28) The fabrication of light strip assembly 20 is carried forward by connecting light strip segments 21 through 28 in a serial fashion. This assembly is carried forward by inserting connector plugs 92 through 98 into connector receptacles 81 through 87 respectively. As mentioned above, and as is set forth below, the insertion of a connector plug into a connector receptacle provides both mechanical attachment and electrical connection. Thus, as connector plug 92 is inserted into connector receptacle 81, light strip segments 21 and 22 are joined mechanically and electrical connection is provided between the conductors (seen below) within light strip segment 21 and those of light strip segment 22. Similarly, insertion of connector plug 93 into connector receptacle 82 performs a similar mechanical and electrical connection. In the same manner, insertion of connector plugs 94 through 98 into connector receptacles 83 through 87 performs a similar mechanical and electrical connection to complete light strip assembly 20.
(29) In the preferred fabrication of light strip assembly 20, the mechanical connection provided between connector plugs 92 through 98 within connector receptacles 81 through 87 respectively is enhanced by additional attachment operations such as thermal or sonic welding. It will be apparent that other forms of additional attachment may be utilized such as engaging spring clips or threaded fasteners. For purposes of improved safety, the attachment between connector plugs 92 through 98 and connector receptacles 81 through 87 is configured to provide a breakaway attachment characterized by separation of the connector plug from its respective connector receptacle when subjected to an excessive force. It has been determined that the attachment of each connector plug to its cooperating connector receptacle should separate when subjected to a stress exceeding a one hundred pound force. This breakaway characteristic is desirable to provide an enhanced safety factor in the unlikely event that a deployed traffic control light strip constructed in accordance with the present invention becomes entangled with a passing vehicle or other similar occurrence.
(30) Connector plugs and connector receptacles used in light strip assembly 20 are fabricated of a molded plastic material which readily facilitates the breakaway characteristic. As a result, the desired separation characteristic is readily provided by controlling the thickness of material utilized in forming each of the connector receptacles and controlling the extent and number of attachment welds utilized in fabricating light strip assembly 20.

(39) Connector plug 91 supports a female connector 136 while connecting wire 126 provides electrical connection between female connector 136 and contact 116. Connector receptacle 81 supports a connector pin 159 which is coupled to contact 119 by a connecting wire 149. A connector plug 92 is shown inserted into connector receptacle 81 for purposes of illustration. Light strip segment 21 includes an LED unit 41. LED unit 41 is formed of a high strength material such as high strength plastic or the like which is either transparent, color tinted or light transmissive frosted material. LED unit 41 includes a dome 49 which protects light emitting diode 40 supported within LED unit 41 in the event that a vehicle runs over LED unit 41. In addition, dome 49 transmits light energy emanating from light emitting diode 40. Connecting wire 146 provides electrical connection to light emitting diode 40.

(43) In operation, switch 120 is moved to the on position which activates the system components within power and control system 155. Mode select circuit 121 provides mode selection information to microprocessor 160. In response to the mode selection input, microprocessor 160 accesses memory 161. Within memory 161 a software program that is utilized in the operation of microprocessor 160 is stored. Accordingly, in response to the mode selection input and the stored operating program within memory 161, microprocessor 160 configures LED driver 162 to provide operating electrical signals to connector array 166. Light strip assemblies 20, 40 and 50 respond to the applied control and power signals to produce the desired illumination pattern within the light strip assemblies.
(44) As mentioned above, power and control system 155 may be operated remotely utilizing the communication between handheld remote control unit 170 and remote receiver 164. Thus, the user is able to actuate handheld remote control unit 172 to communicate changes in the operation of power and control system 155. The extent of remote operation is determined by the fabrication of the remote control system. In the configuration shown in
(45)
(46) More particularly, traffic control light strip 180 includes a pair of light strip segments 181 and 182 pivotally joined by a hinge 183. Light strip segment includes an extendable member 185 which is joined to light strip segment 181 by a telescoping junction 188. Junction 188 facilitates the extension of extendable member 185 away from light strip segment 181 for a distance of approximately twelve inches. Conversely, extension junction 188 allows extendable member 185 to be moved into light strip segment 181 to a compact configuration in which the overall length is decreased by twelve inches. Similarly, junction 187 facilitates the extension of extendable member 184 away from light strip segment 182 for a distance of approximately twelve inches. Conversely, extension joined 187 allows extendable member 184 to be moved into light strip segment 182 to a compact configuration in which the overall length is decreased by twelve inches.
(47) Light strip segment 181 supports a light transmissive dome 191 while extendable member 185 reports a light transmissive dome 190. Similarly, light strip segment 182 supports a light transmissive dome 192 while extendable member 184 supports a light transmissive dome 193. Each of domes 190, 191, 192 and 193 supports one or more light emitting diodes which provide illumination of each of the light transmissive domes. Extendable member 185 further supports a power and control unit 200. Extendable member 184 further supports a protective lip 186. In accordance with the above-described operation, power and control unit 200 includes a battery power supply together with a microprocessor control circuit which energizes each of the light emitting diodes within domes 190, 191, 192 and 193 to produce the desired illumination pattern selected by the user. Power and control unit 200 further supports an LED work light 195. Traffic control light strip 180 is configured from the open configuration shown in
(48)
(49) More specifically, light strip segment 210 includes an elongated generally flat body supporting a plug connector 212 at one end and a connector receptacle 220 at the remaining end. Light strip segment 210 further supports a power and control circuit 230 which is constructed in accordance with the operational circuit set forth in
(50) A power unit 201 supports a plurality of connector posts 203 together with a pair of spring contacts 204 and 205. Power unit 201 supports a plurality of conventional batteries 202 which by conventional wiring (not shown) are electrically coupled to spring contacts 204 and 205. Power unit 201 is assembled to connector pad 211 of light strip segment 210 by aligning posts 203 with sockets 207 and pressing power unit 201 onto connection pad 211. The alignment of posts 203 with sockets 207 ensures that spring contacts 204 and 205 of power unit 201 are aligned with spring contacts 214 and 215. Once power unit 201 is fitted to contact pad 211, the operation of light strip segment 210 is substantially identical to the operation of light strip segment 21 as a type one light strip segment.
(51) What has been shown is a traffic control light strip which supports a plurality of light emitting diode illumination devices within a plurality of LED units upon an elongated supporting strip. A power and control unit responsive to operator inputs is operatively coupled to the LED units to provide selective illumination patterns of the light emitting diodes. The traffic control light strip is supported by a flexible elongated base member which allows the entire traffic control light strip to be rolled from a deployed configuration to a convenient storage configuration. In an alternate embodiment, the traffic control light strip includes a pair of extendable hinge coupled support members that facilitate folding the traffic control light strip to a closed transport and storage configuration.
(52) While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. Therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
