LED means light emitting diode. Diode is an electronic component which has two
nodes. when power supply is given between two nodes the current flows and emits light from it which is in visible spectrum. Hence light appears from LED lamp. As the energy required for emitting light is very less hence LED lights give very high lumens per watt

What type of light bulb is commonly used in advertising signs and decoration?
Discharge lamps are used in advertisement and sign boards. How is the discharge lamp produce light How is different colours of light obtained from these types of lamps.
Which state help produce light in fluorescent light bulbs?
Which state helps produce light in fluorescent lightbulbs?
What is the name of those swirly light bulbs?
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
Information on CFL light bulbs?
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. The lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
What is the name of the energy saving light-bulbs?
There are two different technologies, fluorescent, and LEDs. Fluorescent light bulbs are more common; LEDs are still too expensive for mainstream use. +++ LED lamps' prices are now very competitive, certainly where I live, and make up for the unit price difference in reduced electricity consumption for a given light output. I have a mixture of incandescent, CF and LED lamps in my home, and slowly going over to LED as the existing lamps expire.
Why are fluorescent lamps brighter than filament lamps?
Fluorescent lamps are brighter than filament lamps because they produce light through a different mechanism. Fluorescent lamps use a gas discharge process that generates light by exciting mercury vapor inside the tube, resulting in a more efficient light output compared to the incandescent process used in filament lamps. This efficiency allows fluorescent lamps to produce more lumens per watt, making them appear brighter.
Why are fluorescent lamps brighter than filament light bulbs?
Fluorescent lamps are brighter than filament light bulbs because they produce light by exciting mercury vapor and phosphor coating, which emits more visible light compared to the incandescent process of heating a filament wire to produce light. Additionally, fluorescent lamps are more energy-efficient and have a higher luminous efficacy, meaning they produce more light for the amount of energy consumed compared to filament light bulbs.
What are the different types of light?
Incandescent Lamps Light Emitting Diode Neon Lamps Fluorescent Tubes Compact Fluorescent Lamps Halogen Lamps Metal Halide Lamps High Intensity Discharge Lamps Low Pressure Sodium Lamps High Pressure Sodium Lamps
What type of light bulb is commonly used in advertising signs and decoration?
Discharge lamps are used in advertisement and sign boards. How is the discharge lamp produce light How is different colours of light obtained from these types of lamps.
Why flourecent lamp are better source of light than incandescent lamp?
Fluorescent lamps are more energy-efficient than incandescent lamps because they produce light by exciting mercury vapor with electricity, resulting in less heat loss. They also have a longer lifespan and produce more light output for the amount of energy consumed compared to incandescent lamps. Additionally, fluorescent lamps come in various color temperatures, allowing for more customizable lighting options.
Which state help produce light in fluorescent light bulbs?
Which state helps produce light in fluorescent lightbulbs?
What are the different types of fluorescent light bulbs available in the market?
There are three main types of fluorescent light bulbs available in the market: compact fluorescent lamps (CFLs), linear fluorescent tubes, and high-intensity discharge (HID) lamps. Each type has its own unique features and applications.
What are some Sources of light energy?
The Sun, Stars, Light Bulbs, Fires, Fluorescent Lamps
What is the name of those swirly light bulbs?
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
Which can give light similar to natural sunlight an incandascent or fluorescent lamp?
Neither incandescent nor fluorescent lamps can provide light exactly similar to natural sunlight. However, fluorescent lamps are closer in color temperature to natural sunlight compared to incandescent lamps. LED lamps with a color temperature of around 5000-6500K are the closest artificial option to mimic natural sunlight.
How much mercury is in a incandesent heat lamp?
Incandescent heat lamps do not contain mercury. They use a tungsten filament that is heated to produce light and heat. Mercury is typically found in fluorescent and HID lamps, not incandescent ones.
What gase use in flurocent lamp?
Fluorescent lamps use a mixture of gases, including mercury vapor and argon, to produce light. When electricity passes through the gases, ultraviolet light is produced, which then interacts with the phosphor coating inside the lamp to create visible light.
