DETAILED DESCRIPTION

[0014] A specialized controller for vehicle warning lights is disclosed. The controller includes a light emitting element on a controller housing, wherein the light emitting element provides light emission which mimics the lighting of vehicle warning lights. Thus, vehicle users can control the vehicle warning lights while easily being able to confirm vehicle warning light use based on the light emitting element of the controller.

[0015] Referring to FIG. 1, a warning light 10 and a controller 20 are disclosed. Warning light 10 has a housing 12 and a light emitting element 14 and is adapted to be placed on the outside of a vehicle. These types of lights are well known in the art and not meant to be limiting. An example is the Pro LED SLP1030, sold by Pro Trucking Products. Although these warning lights can come in different configurations, one configuration is bar shaped. These warning lights are commonly capable of numerous flash patterns, for example 19 or 20 or more different patterns. In the warning light shown in FIG. 1, each half of the light is capable of lighting separately. Warning lights, such as the one referenced above, have control units built into the light itself, allowing the light to be controlled by a simple electrical switch attached to a power supply. There are also lights known in the art that do not have their own control unit but are dependent upon a control unit in a controller. Controllers may have their own control unit or it may be a signal receiver from a controller in the light. The disclosed controller contemplates both.

[0016] In FIG. 1, controller 20 comprises a housing 22, a light emitting element 24 fitted on the housing 22, a control unit 26, and at least one control button 30. In the disclosed embodiment of FIG. 1, control unit 26 includes three control buttons, i.e. 30, 32, 34. In most embodiments, housing 22 and light emitting element 24 have the same shape and style as housing 12 and light emitting element 14. However, this is not required and housing 22 may be any shape that works with the rest of the disclosure. For example, housing 22 may be rectangular or square. In one embodiment, such as the embodiment of FIG. 1, controller 20 and warning light 10 are connected by wires. In the embodiment of FIG. 2, controller 20 and warning light 10 are wirelessly connected through a wireless transmitter 28 and wireless receiver 16. In this embodiment, controller 20 may not have an independent control unit and may be controlled completely by the control unit (not shown) in warning light 10. As is understood, in this situation synchronization of the light emitting elements is not required as controller 20 is a signal receiver. This embodiment has functionality to send a signal to controller 20 to display a different light pattern than what is being displayed on warning light 10. In most embodiments, light emitting elements 14 and 24 are LED lights. However, the type of light emitting element is not meant to be limiting. Any appropriate light emitting element, as well as any color of light emitting element, can be used. For example, several different types of LED lights such as SMD LED, COB LED, Dip LED, OLED, RGB LED, CMYK LED, and QLED are contemplated.

[0017] Controller 20 controls the light pattern of warning light 10 as is generally known in the art. In one embodiment, controller 20 acts simply as an electrical switch. Warning light 10 is connected to a power supply (not shown) through controller 20. Controller 20 has three control buttons 30, 32, 34 in the embodiment disclosed in FIG. 1. However, it is to be understood that the order and number of buttons is not meant to be limiting as long as the buttons allow controller 20 to be used as an electrical switch for warning light 10. In the embodiment of FIG. 1, control button 34 is this electrical switch and turns the entire system, i.e. the controller and the warning light, on or off. Control button 30 controls the pattern changes of warning light 10 and controller 20. In this embodiment, controller 20 has its own embedded control unit 26 and can be controlled independently of warning light 10. For example, in the wired embodiment of FIG. 1, controller 20 can be detached from warning light 10 but remain attached to the power supply (not shown). Controller 20 can also be battery powered, such with one or more internal batteries.

[0018] Control button 30 can be held for a predetermined period of time, i.e. 10 seconds, to synchronize the light emitting elements of warning light 10 and controller 20. In most instances, control button 30 is pressed multiple times to cycle through the available warning light patterns. Control button 32 turns off light emitting element 24 of controller 20. In some embodiments, controller 20 is programmed to turn off light emitting element 24 automatically or manually after a preset period of time. This can reduce power consumption and avoid glare. Generally these control buttons can be used while the vehicle is in use.

[0019] With reference to FIG. 3, an operating instruction from controller 20 instructs light emitting element 24 to match the mode of lighting element 14 on warning light 10. As stated above, in many cases, this operating instruction is depression of a control button 30 on controller 20 for a certain period of time, which can be about 5 seconds, about 10 seconds, about 15 seconds or the like. Then, when an operator instructs controller 20 to change warning light 10 to a different lighting mode by engaging control button 30, light emitting element 24 is switched to the same lighting mode. Different lighting modes for warning lights, such as flashing, left only, right only, etc., are known in the art and are not meant to be limiting. Any possible lighting mode that will work with controller 20 and warning light 10 is contemplated. After this instruction, even if the light emitting element 24 on controller 20 is turned off, when it is turned back on, it will continue to match the lighting mode of light emitting element 14 without requiring new synchronization. Warning light and controller may also optionally include indicator 17, which indicates if the entire system is on or off. In many cases, indicator 17 is a LED light.

[0020] In the disclosed embodiments, light emitting element 24 is disposed along the periphery of controller 20. For wireless controllers, light emitting element 24 may be completely around the periphery of controller. For wired controllers, light emitting element may be around the periphery of controller 20 except for where the wiring goes into controller 20. This allows light emitting element 24 to send light out in all directions when on. The positioning of different light emitting elements on controller 20 are anticipated. For example, controller 20 could have two individual lights on each horizontal end of controller 20, which match the lighting pattern of warning light 10. Or light emitting element 24 is disposed around only the horizontal edges of controller 20.

[0021] Because the lighting pattern on the controller can match the lighting pattern of the warning light, the disclosed device allows a vehicle operator to easily and immediately determine if they have entered the intended pattern for the warning light. It does not require learning of the meaning of different controller lights, such as what has previously been known in the art. This is significantly safer than having the operator try to check the pattern on the warning light by checking the mirrors or looking out the window. It is also a convenient time saver for the operator as the controller can be placed anywhere in the vehicle interior that the operator prefers. Thereby the disclosed controller is more convenient to use.

[0022] A further embodiment is disclosed in FIG. 4. In this embodiment, controller 20 controls a plurality of warning lights 10.

[0023] FIG. 5 demonstrates an exemplary process of use of controller 20. Briefly, in step 210 voltage is placed into the system. In most cases, this will be power coming from wiring from the vehicle. However, it is to be understood, that any power source, including one or more batteries within the system are contemplated. In step 212, warning light on/off electrical switch is activated. In the embodiments of the Figures, this switch is a control button 34. However, the electrical switch may be in any shape that allows the warning light on/off switch to be activated. For example, a physical switch may be used. Once warning light on/off switch has been activated, Step 214/Step 216 instruct warning light 10 and controller 20, respectively to display a light emitting pattern. If an operator wishes for warning light 10 and controller 20 to be synchronous, mode switch is depressed for 10 seconds as is demonstrated in step 218. Following synchronization, control button 30 can be cycled through such that warning light 10 displays the desired pattern (Step 220). This pattern is then displayed on both warning light 10 and controller 20 (Step 222). If an operator does not want controller 20 to emit light, the light to controller 20 can be turned off at any point in the process by turning control button 32 off (Step 201).

[0024] Controller 20 can be detachably or permanently attached in any position in the interior of a vehicle. For example, the controller can be detachably attached using hook and loop fastener. The configuration of light emitting element 14 disclosed in the Figures is especially advantageous in this regard because it emits light in all directions. Therefore, attachment of most angles and positions allows an operator to determine the pattern of the warning light even if part of controller 20 is blocked from view.

[0025] Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the disclosed device in its broader aspects is not limited to the specific details and the representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general concept as defined by the appended claims and their equivalent.
