hello ,
I need a low wattage invert er board for led lighting at home .
Please give me ,Any company address or shop (from india)

you can design and make one for a very low cost

You can design one yourself.Use MC34063A and DIY inductor.The IC is available for @ Rs10 @ sunrom Rs12 @ ventor.and at local shops for @Rs30.Make quick search in google for schematics.

If you know the input and output voltages required, you can design the inverter yourself.

You can build a boost converting employing a general purpose PWM controller such as MC34063 or UC3845. If voltage difference between input and output is very high, you can use a transformer-isolated push-pull converter circuit. You may also use flyback or forward topologies.

If you use push-pull converter, you can simply use SG3525. A simple resistive divider from the output can be used to provide feedback. If load is small and input voltage is approximately constant, feedback may even be omitted.

Hope this helps.
Presuming you have a DC source, since you ask for an
inverter, you might just prefer to buy LED "bulbs" that
are suitably rated. I've recently seen families of 12VDC
and 12V AC/DC bulbs in various base styles, for fairly
cheap (well cheaper than the packaged residential
AC LED bulbs).

And at low voltage and low power, you might also find
that dropping the left-over voltage from (say) a 12V
battery running three 3.5V LEDs, is of the same order
of inefficiency as most DC-DCs - 10.5/12V is ~ 88%,
leaving 12% of the power as inefficiency to be shed in
a limiting resistor. In this case you can source chip LEDs
from most distributors, a resistor from anywhere, and
be good to go for very little money, at higher outputs
than the "bulbs" I mention originally.
