LED Projector

Quick Answer: An LED Projector is a digital projector that uses light-emitting diodes as its light source instead of a lamp, projecting the image from a laptop, document camera or other video source onto a screen or wall. An LED projector for classrooms reaches full brightness quickly and runs cooler than lamp-based designs, which suits rooms where it is switched on and off through the day.

LED Light Source Compared with a Lamp

Older data projectors use a high-pressure lamp that needs a warm-up period, a cool-down fan run after switch-off and periodic replacement. LED light sources generally switch on almost instantly, produce less heat, need no lamp changes and last considerably longer, so maintenance in a school is simpler. Their weakness is brightness: many compact LED projectors are less bright than lamp or laser models, which matters in rooms with daylight. The brightness, resolution, inputs and throw distance of this model are not given in the listing, and these determine how large and clear the image will be.

In science teaching a projector does more than show slides. Connected to a laptop, it displays live graphs from data loggers during a practical; with a camera eyepiece or document camera it enlarges a microscope field, a dissection or a titration so every student sees the same detail. Pair it with a screen suited to the room, such as a manual projection screen in a classroom or a motorised projection screen in a hall.

Specifications

Applications

• Showing lesson slides, videos and simulations in classrooms and laboratories.
• Projecting live data-logger graphs during physics, chemistry and biology practicals.
• Enlarging microscope images from a camera eyepiece for whole-class discussion.
• Presentations and training in staff rooms and small halls.

Care and Safe Use

• Keep the air vents clear and do not cover the projector while it is running; LED units still produce heat.
• Clean the lens only with a lens brush or a soft lens cloth.
• Never look into the lens when the projector is on, and remind students not to stand facing the beam.
• Use a proper mount or stable table, and route power and video cables so they cannot be tripped over.

Why Choose LabEquip

LED projectors are ordered by schools and colleges fitting out smart classrooms and laboratories where maintenance time is limited. LabEquip lists this projector in the General Lab Products range; tell us the room size and the sources you need to connect on the contact page.

Frequently Asked Questions

What is the advantage of an LED projector over a lamp projector?

An LED light source reaches full brightness almost at once, needs no lamp replacement and runs cooler. Lamp projectors are often brighter for their size, but need warm-up, cool-down and periodic lamp changes.

Is an LED projector bright enough for a sunny classroom?

It depends on the model’s rated brightness and the room. In rooms with strong daylight, use blinds or choose a brighter projector, since any projected image loses contrast in ambient light.

Can I connect a digital microscope or camera eyepiece?

Yes, if the camera outputs a signal the projector accepts, such as HDMI, or through a laptop running the camera software. Match the camera’s output to the projector’s inputs before the lesson.

How far from the screen should the projector be placed?

That depends on the throw ratio of its lens, which is the distance divided by the image width. A lower throw ratio gives a bigger picture from closer. Measure the room before mounting and check the ratio in the projector’s manual.

Does an LED projector need a cool-down before unplugging?

LED projectors generally need little or no cool-down compared with lamp projectors, but switch off with the power button and let the fan stop before unplugging, as the manual advises.

How do I clean the projector?

Switch off and unplug it, dust the vents with a soft brush or low-pressure air, and clean the lens with a lens cloth. Do not spray liquid onto the projector.
