LED/Light bulb combination flasher

#This invention relates to generally to vehicle lighting or road safety warring lighting, which includes a flasher to enable the lamp or lamps to flash all together or sequential or More particularly, the invention relates to vehicle signaling lamp flashers with the optional audible capability that can be added the circuit, which can be turned on or off and can operate all type of LED lamps and standard light bulb lamps being produced by lamps manufacturers worldwide.

#The transportation industry widely uses many type of signaling lamps to provide autos; truck and trailers pulled behind many type vehicles and other vehicle extensions with the ability to signal to other vehicles. Ordinarily, these lamps must perform the functions of a taillight, turn signal and stop light with the use of a flasher switch in a given situation. The term signaling lamp is used herein to refer to lamps capable of performing any or all of these functions. State and federal laws typically require signaling lamps in an effort to ensure safe driving on all roadways. One reason for the concern for safety is not all turn signal flasher will operate with a standard light bulb lamp and LED lamps. Most turn signal flasher being mechanical or solid state will not work with LED lamp that have few diodes or with and many standard light bulb lamps. Also drivers of auto and trucks and other types of heavy equipment forget that their turn signs or hazards are on or they can't hear it, or is does not automatically cancel (or they don't see it flashing on their dash panel). Also, large trucks with very large trailers often have significant blind spots, which can present a hazard to other motorists. For example, when a truck driver desires to change lanes, the driver can do no more than pay close attention to the side mirrors and properly use the vehicle turn signal. The turn signal triggers a signaling lamp flasher, which generates intermittent contact between the vehicle power source and the signaling lamp to create a flashing light. An inattentive motorist, however, can easily be caught by surprise in this scenario especially if the truck driver or automotive driver forgets to cancel the turn signal, or the turn signal fails to cancel by itself (and if the motorist fails to see the flashing lights). In fact, motorists momentarily taking their eyes off of the vehicle in front of them cause many accidents each year. There is therefore a substantial need to provide signaling lamps for automotive and large trucks and tractor-trailers with the ability to better obtain the attention of the operating driver of the auto or truck.

#Another important consideration to note is that it would also he very beneficial to alert the truck driver that the signaling lamp is operating properly or that the lamps are flashing. For example, if a signaling lamp fails due to a current overload or short, the truck driver will have no knowledge of the failed signaling lamp and will therefore continue to operate the vehicle as if nothing is wrong. Typically, the driver will remain unaware of the problem until he receives a ticket or another driver notifies him.

#A more complete appreciation of the invention and the many attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with accompanying drawings, wherein:

#FIG. 1 is a basic schematic of a system employing the signaling lamp flasher of the present invention.

#FIG. 2 is a circuit diagram of the signaling lamp flasher of the present invention.

#Turning now to FIGS. 1 and 2, the signaling lamp flasher, indicated generally at 10, includes a flash control device 40, an audible flash circuit 30, and a circuit protection device 20. These elements generate audible sound and control intermittent contact between a power source 80 and a light source 90 in response to a voltage pulse from the power source 80.

#It should be understood that both the signaling lamp flasher 10 and the light source 90 could be located within the same signaling lamp as one unit.

#The audible flash circuit 30 includes an IC input circuit 50, an IC 60, and an IC output circuit 70. The IC input circuit 50 has a source capacitor 51, an input transistor Q1, a plurality of input current resistors R2 & R3, an input diode DI, and a zener diode D2. The IC output circuit 70 has an IC transistor Q2, an output relay 72, a plurality of output current resistors R4 & R5, a buzzer 74, a buzzer transistor Q3, a plurality of isolation capacitors C3, and a grounding diode D3.
