Different Types of LED Lights
A good quality LED light can serve for tens of thousands of hours. Generally, 3–5 times the life of a CFL and about 30 times the life of a common incandescent.
What is LED Light?
An LED, or Light Emitting Diode, is a semiconductor device that emits light when an electric current is sent through it. Simply put, LED light is created by a phenomenon called electroluminescence. In this process, electrons recombine with "holes" in the solid-state material and emit energy in the form of light photons. It is really very different from the way traditional bulbs work. In a typical bulb, the filament becomes hot and gives off light by consuming energy in the form of heat. In a CFL bulb, UV light is emitted by ionized mercury vapor. LEDs, however, emit light directly without using a hot filament or toxic mercury vapor. They are thus much more efficient and safe.
In real life, that is a matter of not having to change bulbs so often. It saves huge sums of money on electricity bills. LEDs are also cleaner and more robust. Compared with fragile glass bulbs, the majority of LEDs have tough epoxy or plastic lenses that will withstand shock and vibration. They emit virtually no heat, so they're cooler to the hand and less dangerous to cause fires. To put that in perspective, 90% of the energy output of an incandescent bulb goes into heat dissipation.
Types of LED Lights
LED technology is available across a broad base of packaging and shapes to have varied applications. It is possible to characterise LEDs by package/construct type, by fixture type, and by colour/feature. A brief guide to the major groupings is as follows:
LED Chip Types (Construction)
The production process of the LED chip determines the size, luminescence, and destination. DIP, SMD, COB, and MCOB.
DIP (Dual In-line Package) LEDs:
The original old LEDs from the 1960s. A DIP LED consists of discrete individual red, green, and blue diodes in a bulb form epoxy with two-sided lead wire. The bullet-shaped LEDs, typically ≤5mm in diameter, are also very heavy-duty and very bright. These are suitable for best outdoors on billboard and scoreboard illumination.
DIP LEDs are rugged and weatherproof, hence they light up very effectively even under sunlight commonly used on very large billboard signs. However, as all diodes are discrete, DIP modules have lower "pixel" resolution and do not appear as smooth, therefore, suitable best on coarse-display applications.
SMD (Surface-Mounted Device) LEDs:
Current LED bulbs, strip lighting, and displays commonly use thin, wafer-like chips. In an SMD LED, one chip on the PCB board contains three diodes (RGB), which provide enhanced resolution, a slim build, and better color combination. SMD LEDs like the omnipresent "5050"- or "3528"-type ones are remarkably versatile. They go into lighting bulbs in houses, under-cabinet lighting, strip lighting, and digital displays.
In that they are surface-mount, SMD diodes offer the fixtures a small size and power efficiency. SMD technology is also employed in certain TV backlights, LED strip lighting, and floodlights as a way to offer foldable, uniform lighting.
COB (Chip-on-Board) LEDs:
COB designs place multiple LED chips side by side on a common substrate under a shared phosphor coating. It produces one giant emitting surface. COB modules offer very high lumen output in an immensely tiny footprint. The optimal packaging for downlights, flood lights, and high-brightness spotlights. Because COBs use a single electrical circuit, no matter how many chips they contain. They offer greater convenience and generally deliver more efficiency, producing more light per watt than discrete LEDs in a package.
COB lamps have a 50,000+ hour lifespan and offer rugged, uniform lighting without the grid effect from discrete LEDs. Designers use COB arrays wherever they want multiple lights from a single fixture. For example, in LED floodlights, track lights, and panel lights.
MCOB (Multiple Chip-on-Board) LEDs:
An extension of COB in which some COB chips are connected in series on one substrate. MCOB takes advantage of the high output characteristic of COB with the further capability of handling lower-power bulbs. In practice, some of the new home A19 and A21 LED light bulbs have MCOB technology. Due to larger chips, the light bulbs can work under high levels of light at normal voltages with average efficiency.
MCOB is a relatively new technology (always in development) that offers a compromise between the very high-output COB and the bulb compactness of the unadvanced bulbs. For end consumers, bulbs that have the MCOB technology are domestic high-power LED lamps that emit more lumens with not very high wattage.
CSP (Chip-Scale Package) LEDs:
CSP LEDs are still new and use a tiny package where manufacturers position the raw LED chip directly on the PCB without any customary casing. CSP chips are tiny, most often in a few millimeters, and highly efficient with excellent heat dissipation. They drive at high speeds across a very small area. They are very desirable in high-end backlighting, automotive lighting, and small lights. CSP chips are significantly smaller than COB chips and fit easily into areas with limited space. However, because CSP technology is expensive, developers use it only when they prioritize high performance and size minimization over cost.
One chip per application, DIP on the giant outdoor displays, SMD on the standard interior light or floodlight, and a flexible strip. COB/MCOB on the high-power bulbs (spotlight, floodlight), and CSP on the high-end miniaturization packages. Chip type will dictate the fitting size and shape, output, and cost. This information is useful when selecting the appropriate LED product for any particular application.
LED Lighting Installations (Applications)
LEDs are available in every conceivable form of fixture and replace almost every kind of generic lamp. General categories of LED fixtures are:
Replacement Lamps/LED Bulbs (Screw-base bulbs):
They are the replacement bulbs (A19, A21, GU10, etc.) for the incandescent or CFLs. In the same equivalent warm white, cool white, or daylight, LED bulbs provide the same light at much lower wattage. For instance, a 12W LED bulb will be a replacement lamp compared to a 100W incandescent equivalent at the same level of lumens. LED bulbs are very popular as general home lighting. Because they substitute the existing fixtures and have a lifespan of the order of tens of years.
LED Strip Lighting:
Versatile strips with SMD LEDs on them. Ideal for edge lighting base edges under cupboards, around the rear of television sets, or along a room. Available in a range of densities, e.g., 60 or 120 LEDs/m and colours, one-colour white or RGB multi-colour. Strips allow simple attachment of contiguous strings of light around a room, stairwell, or motor car interior. Occasionally, with a remote control or RGB colour-mixing function.
LED Downlights and Panels:
Recessed ceiling panel LEDs, typically as 2x2 or 2x4 ft, go into offices, home kitchens, and basement levels as a replacement for fluorescent troffers. They offer broad, flat lighting. Electricians install LED downlights and recessed can lights into ceiling surfaces for ambient or task lighting. LEDs suit this purpose especially well because, unlike regular bulbs that spread light. They can direct light through panel mounting or focused beams to illuminate a room without wasting energy on reflection.
LED Floodlights :
People use high-wattage outdoor bulbs to light up large areas such as yards, driveways, and outdoor structures. Typical LED floodlights will include COB technology as part of them for high-wattage and heavy-duty enclosures with solid IP ratings for all-weather construction. LED floodlights replace metal-halide floods with a far more energy-efficient option. Users can power them with motion detectors for security, activating the lights when the detector senses movement. GlowFashionGear offers quality LED floodlights that provide rugged outdoor fixtures at reasonable prices.
Area and Street Lights, LED:
Municipal-type fittings for roads, car park areas, and footpaths. They will tend to utilize multiple LED modules with optics to throw the light downwards. City centre towns are quickly retrofitting LED street light installations due to their very long life and massive energy saving, typically reducing streetlight power usage by 50-70%. In reality, an international test comparing LED street lighting with standard lamps in 12 large towns realized an energy reduction of up to 85%.
LED Tube and Panel Boards:
People use linear LED tubes, which replace T5 or T8 fluorescent fixtures, in many lighting setups. Rear-lighted LED boards replace the plastic or wooden lighting often found on shelving and signs. Advertisers and businesses also employ LED modules in panels, exit signs, and other displays.
Smart LED Luminaires:
All LEDs these days are "smart". They have internal wireless controls as well as can be controlled through apps, remote, or voice. Smart bulbs and light fixtures allow you to schedule time for on/off, brightness, as well as color (RGB). For example, you can have your smart LED bulbs dimmed when you have a movie night or blue light when you need to be awakened when you get up the next morning.
Solar LED Lights:
Autonomous exterior bulbs that work on the principles of a solar panel and an interior battery. They consist of solar garden lights, solar street lights, and solar spotlights. They save energy through the use of LEDs and get recharged without wiring and electricity during the day.
LED Types (Color & Characteristics)
LED lamps contain variable colors and combinations of characteristics to produce diverse outputs.
Warm White or Cool White, or Daylight:
LED bulbs also come with a color temperature rating (Kelvin). Warm white (approximately 2700–3000K) is a yellow, cozy one, like the older incandescent bulbs; cool white (3500–4100K) is white/neutral, like kitchens and work areas like offices; daylight (5000–6500K) is blue and very bright, except for detail work or outdoor lighting.
For instance, DOE defines an average incandescent light bulb as approximately 2700K (warm). Homes use warmer LEDs in bedrooms and living rooms, when you're relaxing, and cold LEDs in work areas such as bathrooms and kitchens.
RGB and Color-Changing LEDs:
RGB LEDs contain red, green, and blue chips (or employ special filters) that get changed in color by mixing and combining.
It allows them to be made into any color. The RGB LED light fixtures (stripes, smart bulbs) provide you with the option of selecting hundreds of colors and interactive scenes within a home or party theme. For instance, you can set RGB LED stripes under a bed or behind an LCD TV to illuminate any color for a party, or set them to solid blue for a movie night. If you place an RGB LED in a fixture, it uses three diodes: a red, a green, and a blue one.
Dimmable LEDs:
The majority of units and bulbs are now dimmable by the correct wall switch or via the phone app. An LED dim can be as sluggish as an incandescent dimmable with a knob.
Tip: Opt for an LED-compatible dimmer so that you will be sure the dimmer will work because the previous dimmers had higher ratings.
Motion-Sensor LEDs:
All interior and outdoor securities such as exterior LEDs, incorporate built-in PIR motion sensors. They will switch on the light automatically when they sense movement at night. An example is a low-power or off COB floodlight motion-sensor light, which will flash when approaching, is energy-saving, and convenient to use. Homeowners can also install optional auto-on/off sensors in indoor halls and bathroom areas to conserve even more energy.
Waterproof/Rated Outdoor LEDs:
Manufacturers construct outdoor LED bulbs (streetlights, floodlights, garden lights) with high IP ratings (e.g., IP67, IP65) to protect them against dust and water. They will withstand rain and snow. Most Solar LED path lights are weatherproof, too.
Conclusion
Replacing with LEDs is a two-fer: more light, longer light, and money and energy saved in the process. LEDs provide plenty of options. They vary from warm, cuddly bulbs in the bedroom to smart, color-shifting strips for a party, to flash outdoor floodlights for security.
