We all know the importance of lighting in the home, but we always find that lighting is very expensive, and we don’t know how to solve this problem. In order to save energy, you can use a variety of light bulbs, which can keep your home bright and save a lot of energy.
Below are some detailed information about the bulbs and all the information about led light.
Kinds of light bulbs
There are 3 basic types of incandescent bulbs, CFL, fluorescent and halogen bulbs, but in addition, we also have many bulbs, such as LED bulbs, which can save a lot of energy and reduce lighting costs.
These bulbs are the cheapest and most commonly used bulb types. When the current heats the tungsten filament, it will emit light, which emits light but consumes more energy than other light bulbs. You must know which kind of bulb is suitable for your family and is within your budget. Now, people no longer use incandescent bulbs. You can check out best led light manufacturer in India.
Compact fluorescent lamps or compact fluorescent lamps are energy-saving lighting alternatives to incandescent bulbs because they are not suitable for home use and other places. Incandescent bulbs are in danger of breaking at any time, so people who use incandescent bulbs are very dangerous. In 1976, Edward Hammer created the energy-saving light panels.
This is a low-pressure mercury vapor discharge lamp that uses fluorescent lamps to emit light. It is used for portable task lighting or other special applications, such as when high luminous output is required or low-temperature high-efficiency lighting is required. It produces light when freely accelerating electrons collide with atoms in a hot gas.
In this case, even if the mercury content is small, it is dangerous you have to use best wire for decorate your lights in home . Mercury is a toxic metal that can damage the brain, nervous system and kidneys. Depending on your choice, which kind of bulb you are going to use, for this you must also understand all bulbs and the advantages and disadvantages of bulbs.
It is also called a halogen tungsten lamp. It is a tungsten filament lamp whose tungsten filament is sealed in a compact transparent envelope-like object, which is filled with inert gas and a very small amount of halogen, such as bromine. Elmer Fridrich and Emmett Wiley established this lamp in 1955 and 1980 to become lighter and more advanced.
In 1962, 33-year-old scientist Nick Holonyak (Jr.) created the first LED bulb. Unlike other bulbs, LED bulbs do not emit harmful radiation and are therefore safe. It consumes a small amount of energy and is therefore pocket-friendly. It is brighter than other bulbs and will not cause any accidents or dangers like other bulbs. LED bulbs are reasonably priced and reliable. Nowadays, it is mainly used by people, and there are no shortcomings.
How to choose a light bulb – selection criteria
- The main criteria for choosing a bulb are well known:
- The light bulb must be economical, that is, consume the least amount of electricity;
- The bulb should provide a comfortable lighting level;
- The bulb must be harmless and safe to use.
- In addition, you should pay attention to other parameters, which we will discuss below:
- Type of bulb (incandescent lamp, LED lamp, etc.);
- The type of lamp holder (actually the size of the lamp);
- lamp shape.
Select the type of light bulb
Dozens of electric light sources (ie lamps) are produced all over the world, but most of them are special-purpose commodities. This kind of lamp is used in various fields of human activities, including medicine and industry. Generally, most of us deal with three types of light bulbs every day:
- incandescent lamps (also called filament lamps );
- fluorescent lamps;
- LED bulbs.
What is luminous efficiency and how does it differ in different types of lamps
Luminous efficiency is calculated as the ratio of the luminous flux emitted by the lamp to the power consumed by the lamp. This parameter indicates the efficiency and economy of the light source. Measured in lumens per watt (lm/W).
When calculating, you need to consider
- The power loss of the LED lamp power supply-from 1 to 5%;
- The loss of light when passing through the diffuser-from 0.2% to 2.5%;
- Loss of reflector, protective glass, etc.;
- Loss due to the inductive or capacitive nature of the power load.
