There are many lamps in automotive vehicles such as interior lamps, reading lamps, and courtesy lamps. We call them ‘Automotive Room Lamps’ and they promote driver’s convenience.

LED lamps are better than incandescent lamps in energy efficiency because of low power consumption and long life time. This is why LED lighting is the mainstream of automotive room lamps.

IKSemicon, which is the leading company of automotive ICs’ design & manufacturing, released an automotive room lamp module called IKM3004. It has many superior characteristics compared to existing commercial solutions.

IKM3004 includes 3 LED lights with 3 driver ICs and it has just 1.2watt power dissipation providing up to 65 lumens of brightness. One of its powerful functions is reverse voltage protection.

With a bridge diode, IKM3004 operates regardless of any polarity during the assembly of an automobile car. It enables to make compact size of PCB which consists of small components including only one bridge diode.

As you can see, the existing solution needs more than one PCB with many components. However, IKM3004 with PCB is extremely simple.

IKM3004 has following features.
- Supply voltage up to 18V
- SMD Top view 5450 type
- 120 degree of Beam view angle
- High current accuracy at supply voltage variation
- Output current reduction at higher temperature which is the negative thermal coefficient
- No EMI
- And Protection of reverse voltage

As you can see this application circuit, IKM3004 needs only one bridge diode and TVS diode is optional by customers’ requirements.
With this IKM3004 solution, customers can have a cost benefit and convenience with easier assembly process.
