Light-Emitting Diode (LED) Manufacturer,Supplier and Exporter in India

Light-Emitting Diode (LED) (Product Code: SCL2529/036) is a white luminescent diode that glows when current passes through it in the forward direction, making it a clear visual indicator for circuit and semiconductor lessons. The capsule is at least 5 mm across and the wire ends are tinned copper, so it can be soldered, clipped or pushed into a circuit board. Schools use it in LED characteristics experiment kits and simple circuit builds; it is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

Younger classes use the LED as a polarity test: connected one way it lights, reversed it stays dark, which introduces the idea that some components only let current pass in one direction. In senior practicals it becomes a subject of study in its own right, with students raising the voltage in small steps and recording the point at which it starts to glow, then comparing that turn-on voltage with other LED colours.

Because it draws little current, the white LED also serves as a status light in student-built circuits such as a light-sensing switch or a continuity tester. Always wire a resistor in series with it, since connecting an LED straight across a battery can burn it out. Tinned leads take solder easily, but keep soldering brief to avoid overheating the capsule. It is an inexpensive addition to any electricity experiment kit for school benches.

Supplier

Components such as this LED are sourced and supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from its base in Ambala, Haryana, so schools can order them together with other circuit apparatus. Our company profile has more about the business.

Frequently Asked Questions

What colour and size is this LED?
It is a white luminescent diode with a capsule diameter of at least 5 mm. For a red LED, see the related item above.

Which resistor should I use with it?
A series resistor is always needed; its value depends on your supply voltage. Ask us with your circuit details and we will suggest a suitable value.

Why does my LED not light?
The most common reason is reversed polarity. Swap the leads round; if it still stays dark, check the battery and the connections.

Can the leads be soldered?
Yes. The wire ends are tinned copper, which accepts solder readily. Keep the iron on the joint only briefly.

Are larger quantities available?
Yes. Pack sizes are not fixed on this listing, so tell us how many you need for your classes and we will confirm supply.

Do you ship outside India?
Yes. Quote code SCL2529/036 with your quantity and destination; we supply customers in India and international markets.
