What are the parts of LED bulb?
The Anatomy of a LED Light Bulb
- Lens/Optics. Due to the brightness of LEDs, a lens (or optics when used on omni-directional lamps) is used to evenly distribute the light.
- LED Chips. LED chips are the components that create the light.
- Heat Sink.
- Circuit Board/Driver.
- Housing.
- Base.
How does an LED light bulb work?
An LED bulb produces light by passing the electric current through a semiconducting material—the diode—which then emits photons (light) through the principle of electroluminescence. Don’t let that big word scare you! It essentially means that a material (in this case, the diode) casts light when power is applied to it.
How make LED bulb step by step?
How to make LED Bulb and required Material for making LED bulb
- Material for making LED bulb.
- LED Driver circuit.
- Assemble PCB components:
- Mount the LED board on aluminum heatsink:
- Mount the LED driver in Housing:
- Add the input wire to the metal cup of the Driver circuit:
- Crimp metal cup with housing:
Which material is used in LED bulb?
The material used most often in LEDs is gallium arsenide, though there are many variations on this basic compound, such as aluminum gallium arsenide or aluminum gallium indium phosphide.
How do you make a homemade LED bulb?
Components Required for DIY LED Light Bulb
- C1 – 135J 400V Metal Film Capacitor.
- B1 – Bridge Rectifier (4 Diodes can be connected in Full wave Rectifier mode)
- C2 – 22µF 35V Electrolytic Capacitor.
- R1 – 100KΩ Resistor (1/4 Watt)
- LED 1 to 12 – 8mm LEDs.
Are all LED light bulbs the same?
Not all LEDs are the same Unlike Compact Fluorescent Lamps (CFLs), LEDs are currently not regulated for energy efficiency – or characteristics such as colour. This means you may experience greater variation in their performance.
Do LED lights run off AC or DC?
In most applications, LEDs are driven by a DC power supply, but AC offers several significant advantages. Lynk Labs has developed technology that allows LEDs to be driven directly from an AC supply. LEDs are usually considered to be DC devices, operating from a few volts of direct current.
How does the schematic symbol of the LED map to the physical?
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) of the LED is the anode. The cathode is marked on the rim of the LED body with a flat area shown in the diagram.
How to set the output voltage of the led series?
Here’s the finalized design for you all: You just have to adjust the pot to set the output according to the total forward drop of the LED series string. Meaning, if the total voltage of the LED series is say 3.3V x 50nos = 165V, then adjust the pot to get this output level and then connect it with the LED string.
How do you connect an led to a circuit?
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) of the LED is the anode.
What is the base of an LED light bulb made of?
The base of the unit is a one-piece plastic housing that holds the ac/dc converter circuit board. Two wires connect it to the pentagon-shaped tower holding 18 LEDs, three on each face. The connections between the boards appear to have been reflow soldered.
