Welcome to

Manufacturing & Repairing of LED Bulb (MRLB)

This is a Technical course for UG and PG-level students. The course is designed to develop an entrepreneurial mindset among the students. This course involves the practical application of Electronics. It will boost the skill development credibility and improve the ability of the students in repairing electrical components used in day-to-day life. Finally, students will be able to assemble and repair an LED bulb on their own. 

Course Objectives and Outcomes: The objectives of the course are –
1. To understand the basics of power electronics and their usage in lighting controls, LED power supplies, and LED drivers.
2. To know about Special safety and handling precautions to be taken during LED luminary testing.

3. Identify dysfunctional components through visual inspection and by use of multi-meter
4. To understand various electronic & electrical components, materials, and their specific
properties & usages

Why Manufacturing and Repairing of LED Bulb?

LED bulbs are electric lamps that produce light through light-emitting diodes and are used in lighting fixtures. These contain a cluster of LEDs, which are mounted on a single base and are packed in diffuser lenses to spread light across a defined space. LED bulbs produce light approximately 90% more efficiently than incandescent bulbs. These bulbs are based on solid-state lighting, which emits light from a semiconductor chip, thereby generating lesser heat than incandescent bulbs. The useful life of these lamps is defined differently than other light sources such as compact fluorescent light (CFL) or incandescent bulbs. LED bulbs do not fail or burn out, instead, they face lumen depreciation in which the brightness of the bulb decreases over time. The global LED bulbs market is expected to expand at a significant growth rate owing to the strict regulatory norms regarding the banning of inefficient light bulbs.

Owing to the longer durability and higher efficiency it is expected that the light market will be occupied by LED bulbs very soon. However, the production of LED bulbs needs to increase, and costs should be reduced. Keeping this in mind the course is designed to train young people in the production of LED bulbs locally. It is believed that this course will help in the generation of entrepreneurs and energy conservation.
