Overhead projectors have been a popular tool in classrooms and business settings for several decades. They are still used today in many parts of India, thanks to their versatility and affordability. Here is a complete information on overhead projectors in India:

What is an Overhead Projector?

An overhead projector is a device that projects an image or text onto a screen or wall. It consists of a flat surface on which the image is placed (often a transparent sheet of paper or plastic), a light source that illuminates the image, and a lens system that focuses the light onto the screen.

Uses of an Overhead Projector

Overhead projectors are commonly used in classrooms for lectures, presentations, and group discussions. They are also used in business settings for presentations, training sessions, and conferences. In addition, overhead projectors can be used for art projects, film screenings, and even as a makeshift movie projector.

Advantages of an Overhead Projector

One of the main advantages of an overhead projector is its simplicity. It does not require any specialized training to use, and it is easy to set up and operate. In addition, overhead projectors are relatively inexpensive compared to other presentation tools such as digital projectors. They also do not require any special software or hardware to operate.

Another advantage of an overhead projector is its versatility. It can project any kind of image or text, including hand-drawn diagrams and notes, printed material, and even three-dimensional objects. This makes it a useful tool for a wide range of applications.

Types of Overhead Projectors

There are several types of overhead projectors available in India, including standard models, portable models, and digital models.

Standard overhead projectors are the most common type, and are designed for use in fixed locations such as classrooms and meeting rooms.

Portable overhead projectors are lightweight and compact, and are designed for use on-the-go. They are ideal for presenters who need to travel frequently or who need to make presentations in different locations.

Digital overhead projectors are designed to work with digital devices such as laptops, smartphones, and tablets. They typically use an HDMI or USB connection to display the image on the screen.

How to use an Overhead Projector

To use an overhead projector, simply place the image or text on the flat surface of the projector. Turn on the light source, adjust the focus and zoom settings, and position the projector so that the image is projected onto the screen or wall. You can then use a pointer or pen to highlight or annotate the image as needed.

Where to buy an overhead projector in India

Overhead projectors can be purchased from a variety of retailers in India, including electronics stores, office supply stores, and online marketplaces. Prices vary depending on the model and features of the projector.

In conclusion, overhead projectors are a versatile and affordable presentation tool that is still widely used in India today. Whether you are a teacher, presenter, or artist, an overhead projector can be a useful addition to your toolkit.

Maintenance Cost of Overhead Projector in India

The maintenance cost of an overhead projector in India can vary depending on various factors such as the brand of the projector, its age, and the frequency of use. In general, routine maintenance tasks such as cleaning the lenses and replacing the lamp can cost anywhere between INR 500 to INR 1500 (approximately USD 7 to USD 20).

If there are any major repairs needed such as fixing a faulty fan or replacing the projector’s motherboard, the cost can be significantly higher and can range from INR 3000 to INR 10000 (approximately USD 40 to USD 135).

It is always a good idea to compare maintenance costs across different service providers and get a quote before committing to any repairs or servicing. Additionally, regular upkeep and maintenance can help extend the lifespan of the overhead projector and reduce the need for expensive repairs in the future.
