What are the Different types of LED Lighting

• Types of LED Bulb. In the recent past, LED lighting used to be fairly limited with few designs to choose from.
• LED Colour.
• Dimmer Switches.
• LED Lighting Tubes.
• SMD LED.
• COB LED.
• Graphene Light.
• Why We Now Use Lumens.

What are the two applications of LEDs?

LEDs are used in applications as diverse as aviation lighting, fairy lights, automotive headlamps, advertising, general lighting, traffic signals, camera flashes, lighted wallpaper, horticultural grow lights, and medical devices.

How is the colour of an led determined?

The colour emitted by an LED is specified in terms of its peak wavelength (lpk) – i.e. the wavelength which has the peak light output. This is measured in nanometers (nm).

What do you need to know about LEDs?

LEDs are like small light bulbs and are available in different sizes and colours. The symbol for an LED used in circuit diagrams is shown here: An LED has a positive lead know as the anode and a negative lead known as the cathode. An LED must be connected in a circuit the right way around – observe the polarity of the LED.

Which is the positive lead of an led?

An LED has a positive lead know as the anode and a negative lead known as the cathode. An LED must be connected in a circuit the right way around – observe the polarity of the LED. The way that the schematic symbol of the LED maps to the physical LED is shown in the diagram below: On the physical LED, the longer lead (or leg)

Why do LEDs have to be connected in series?

LEDs must always be connected in series with a resistor. LEDs are diodes which means that current can only flow through an LED from the anode to the cathode and not the other way around. If an LED is connected the wrong way around in a circuit (anode to negative and cathode to positive) it is said to be “reverse biased” and will not emit light.
