LED Garage Lights: What Are They?
The LED light bulbs are made up of two parts. One part is called the backlight which is made up of a phosphor coating, while the other part is called the emitter or source. These two parts are connected with wires so that they can produce light when electricity flows through them. LEDs have many advantages over incandescent lamps such as lower energy consumption, longer life span, and higher efficiency.
LEDs are very bright and have high brightness levels. They are brighter than incandescents and some fluorescent lamps. There are different types of LEDs used in various applications including automotive, home appliances, medical devices, industrial equipment, security systems etc.
LEDs can be manufactured using a variety of materials such as metal halide (MH), tungsten diselenide (THS) and others. Some of these materials emit blue light whereas others emit red light. The color of the emitted light depends upon the material used to manufacture it.
LEDs are not only useful for their brightness but also because they are cheap and efficient. Manufacturers can use cheaper materials to make LEDs since they do not need expensive semiconductors like those found in incandescent lamps or mercury vapor lamps, which are extremely hazardous to human health due to its toxic effects. LEDs do not contain any toxic materials and hence are considered to be a lot safer than other light sources.
Many companies have started using LEDs in their lighting fixtures. The best thing about LEDs is that they can be used in almost all types of lighting fixtures such as bulbs, tubes, spotlights, recessed lights, and others. They are also available in a variety of shapes, sizes, beam angles and colors.
They are not only used as general or task lighting but are also used as decorative lights due to their different colors, shapes, and beam angles. LEDs are also designed for outdoor lighting. LEDs can be used in tightly packed arrays to form illuminated signs and billboards because they produce very bright light.
The number and size of LEDs being used in the lighting fixture will determine how much brightness it will have. The more LEDs in a fixture, the brighter it will be.
Uses of LEDs
General Lighting: LEDs are best known for their use as general lighting in homes, offices, streets, and other places. This is because they use less energy and last longer than other types of lighting such as incandescent and fluorescent lighting.
Automotive Lights: LEDs are best known for their use in car headlights. They can be used to create a large and intense beam of light or a small narrow beam of light depending upon the requirement. They are also used in car turn signals and brake lights, instrument clusters, and other miscellaneous uses.
Advantages of LEDs
Long Life: LEDs have a very long life span. They can last from 50,000 to 100,000 hours. This is equivalent to 15 to 30 years if it is used for 8 hours a day.
Low Power Consumption: LEDs consume very little power. This is one of the reasons why it has a very long life due to less heat build up.
Low Maintenance: LEDs require little or no maintenance at all. They do not have any filaments that can burn out or bulbs that might shatter. This is one reason why they have a very long life span.
Red and Blue LEDs: Blue LEDs are used in various applications. For example, blue LEDs are used in Blu-ray discs, cell phones and other electronics devices. Red LEDs are widely used as indicators such as the red light indicator on your TV remote.
Green LEDs: Green LEDs are used in various lighting applications. For example, they can be used in traffic lights for better visibility or in applications that need detection such as in sensors, timers etc.
White LEDs: White LEDs were only made possible in the last decade. They are used in many applications such as in flashlights, TV backlighting and other general illumination uses.
Two technologies have made LEDs so useful. The first is the ability to produce white light by combining different colors of LEDs. This allows the creation of infinite shades of colors since each color can be controlled individually.
Before LEDs were available, producing white light involved using an incandescent bulb with a chemical coating on the inside that filters out certain wavelengths of light. This produces a lot of heat and most of the energy is given off as heat rather than light.
The second technology is the advent of high-power LEDs. High-power LEDs are available in a variety of different colors, each with a different peak wavelength. This allows the color of LED to be changed simply by changing the voltage applied to it, a process known as “firing”.
For example, three different colored LEDs (red, green, and blue) can be wired together in a circuit such that the first LED fires whenever electricity is applied to the circuit, the second LED fires whenever the electricity flows from the first LED to the second LED, and the third fires whenever electricity flows from the first to the third. By using different voltages, it is possible to make the three LEDs light up at different times, producing any color that the user desires.
