Police lights circuit

[Savage_28]

Hey guys i'm looking for a diagram circuit for strobe flashing police lights for my r/c cars.I want to use LED's for the project.Can you guys help me with my idea?


Thanks

just stick in small mcu and program it. you are most likely to see tons of tutorials for PIC or whatever you want to use. using delays and lookup tables you can have variety of flashing patterns. I'm sure Nigel's website will have something suitable if not just like that but here are some links (google is your friend):

An 555 times will do.You can find tons of circuits for it (Even in its datasheet)

check this one

check this one this is very simple to make
use one RED led and one BLUE led.
ENJOY!!!!1 :lol:

well police in different countries has different light signs. in north america they have more flashing lights than a small disco club and the paterns change. this is why i suggested programmed chip.... :lol:

Police cars over here have two flashy blue lights.

if the supply is 9V, you could simply use flashing LED. I'm not sure if they have them for lower voltage.

Thanks for the reply guys and the idea's.What i need is a strobe type effect(like a nite club strobe).I know if i want to have the same effect i need a ac version.So proberly a circuit to use 6 L.E.D'S in total.

 

[panic mode]

AC? where did you get that idea?
just get small programmable chip and few LEDs.

u need to use triacs or scrs for that purpose not leds

So you want to use an xeon flash tube?

You need an HV cap,a way to charge it and at trigering transformer.

Someone Electro is right, do you want LEDs or flash tube?

I want to use LED's for the project.

What i need is a strobe type effect(like a nite club strobe).

You could probably get the same effect of a strobe with just using some bright LEDs. Then using a microcontroller, you could have them flash however you want.
Depending on the size of the flash tube, you would either need a powerful battery or a really long extension cord.

What i meant to say i need the same brightness as a xeon tube.Like those cell phones with flashy very bright blue lights

Those have NOTHING like the brightness of a xenon flash tube, they are simply bright LED's.

 

[jrz126]

I agree, but due to the fast flash rate that would be needed, and the power restrictions on an RC car, it kinda seems like LEDs would be the better option. and you could still get a great looking effect depending on how you flash the leds.

WILL THIS circuit work? how can i make it flash 3time L and 3times R .
WHat is d name of the transistor your using here?

Have a look at this thread.

Same thing going on there

if the supply is 9V, you could simply use flashing LED. I'm not sure if they have them for lower voltage.

LEDs with built in flasher circuit operate at 5V.

you know what is the name of the bjt transistor is?:d
