High Brightness and High Voltage Dimmable LED Driver for Advanced Lighting System

In recent years high brightness LED lamps are opening up new opportunities of cost and energy saving towards variety of lighting applications. However they also require LED driver and control circuit compare to gas filled lamps when operating at input AC mains. Thus an efficient driving circuit is essential for its optimal performance. In this paper a remote monitoring and controlling system based wireless sensor network is implemented for LED lighting according to the user’s state, which basically controls illumination intensity of a lighting device according to object movement and brightness of surrounding. Then this system can extend communication capability to the existing street lighting system through the ZigBee and this idea will be very useful for subway, industries and household application to effectively reduce the power consumption.

Light Interference

In an office space, an LED-based lighting system allows you to perform the function of a data transmitter. This article discusses the cost-effective design and development of a data-enabled LED driver that can transmit data along with its receiving part. In addition, this paper clearly outlines the application of the proposed VLC system in an office environment where ambient light interference is a severe issue of concern. The result shows satisfactory lighting characteristics in general for this area in terms of average horizontal illuminance and illuminance uniformity. At the same time, to evaluate real-time and static communication performance, Arduino interfaced MATLAB Simulink model is developed, which shows good communication performance in terms of BER (10–7) even in presence of ambient light noise with 6 dB signal to interference plus noise ratio. Our designed system is also flexible to work as a standalone lighting system, whenever data communication is not required.

Hand Signal

Operation theatre lighting system is a critical component in the operation theatre. Focusing the light to the area of surgery and varying the light intensity is manually done in currently available systems. Disruption of surgeon’s attention and possibility of infection due to non sterilized hands is a major setback of the manual controlling method. This usually requires assistants to adjust the position and intensity of the light system by commands from the surgeon. So, designing an intelligent lighting system for operating theatre which can maintain the intensity values to the required level without shadow effect to the operation area is an important requirement. Proposed system makes use of accelerators in the gloves worn by surgeon so as to track hand movements. Pre defined hand movements can be configured to move the lighting system up, down, left or right. Accelerator input is interpreted for its corresponding movement by controller at transmitter side and it is wirelessly given to the receiver side using an nRF module. At the receiver side the incoming command from the nRF is taken and suitable response generated at the motor driver by the controller to move the lighting device. In the same way predefined hand signal can be used to vary the intensity of the light by using microcontroller to drive an LED driver.
