LED lights, powered by light-emitting diode technology, have become a preferred choice over traditional incandescent bulbs. When an electric current passes through the diode in an LED bulb, it emits light. Key benefits of LED bulbs include higher brightness, absence of heat production, longer lifespan, and greater energy efficiency. LED bulbs come in various sizes, shapes, colors, and temperatures and can be used in vehicles, bicycles, and other applications.
LEDs once limited in popularity due to high costs and limited applications, have become a prevalent choice in lighting technologies. Available in various forms, sizes, and colors, some common types of LED lights include:
1. Dimmer Switches
LED lights are available with dimmer switches similar to other bulbs. These allow you to dim LED lights as and when required. However, regular dimmers that work with incandescent bulbs will not work because LED lights operate at a lower wattage than conventional ones. Also, not all LED lights work with dimmer switches.
LEDs with dimmer switches generally have a smaller dimming range than traditional incandescent bulbs, as they consume far less power. It can also result in an LED bulb not completely switching off at minimum brightness.
Dimmer switches work by reducing the amount of power delivered to the bulb by trimming the leading or trailing section of the waveform. Trailing edge dimmers are more expensive and complicated but offer more features.
All dimmer switches have a minimum and maximum rating, and most manufacturers offer dimmer switch-compatible LEDs. However, there is no guarantee that every LED bulb works with all types of dimmer switches.
2. Mini LEDs
Miniature LEDs are one of the most common LED lights you can find on the market. With advancing technology, the size of LEDs has been steadily growing smaller and more compact. These include chip, nano, and pico LEDs.
Mini LEDs are tiny and are available in a single color and shape. The most common applications of these mini LEDs are in remote controllers, mobile phones, calculators, etc.
One advantage that MIni LEDs have is the more straightforward design, which does not require a heat sink or similar device to control the heat. It allows such LEDs to be used in circuit boards and makes them indispensable across many industries.
You should note that there are three types of Mini LEDs available: Standard, Low-Current, and Ultra-High Output. However, these lights vary in terms of voltage, wattage, and current.
3. Application-Specific LEDs
A significant advantage of LEDs is that they can be easily constructed to meet different types of needs for other users. Application-specific LEDs offer a high level of personalization which is why they are trendy. These LEDs can be further categorized into different types of LEDs such as Lighting, Alphanumeric, Flashing, Bi and Tri-Color, and Red Green Blue, or RGB.
Alphanumeric LEDs are generally used in devices such as older digital clocks. With the advancement of LED technologies, these have become less common in more recent times. Modern LEDs are more flexible and energy-efficient.
Flash LED lighting is another example of application-specific LEDs. These are usually standalone lights that contain an integrated circuit, unlike regular LED bulbs. This circuit flashes a light at a predetermined frequency. Flash lighting is commonly used for signage purposes.
Bi and tri-color LED lights produce two and three-color variations, respectively, using alterations of the current frequency. These types of lights are generally used for signage, accent lighting, and highlighting different sections and spaces.
The final type of application-specific LED lights are RGB lights or Red Green Blue LEDs. These contain transmitters that combine red, green, and blue colors to create new colors, offering numerous possibilities. These lights are used in displays, status indicators, video displays, accent lighting, etc.
4. LED Light Strips
LED Light Strips are LEDs that have a tape that has LEDs and other components mounted on them. These strips are available in many different shapes and sizes, making them highly versatile.
