With LEDs continuing to dominate incandescent and fluorescent models, it's important to familiarize yourself with some LED lighting terms so you can understand the benefits and choose the best products for your application. While LED lighting was primarily used for commercial purposes in its early days, technological advances have also transferred it to residential areas. more and more consumers
Basic Lighting Terms
Light Emitting Diode (LED)
LED (short for Light Emitting Diode) is a semiconductor diode light source that emits light when an electric current is passed through it. During this process, guest diffusion energy is released in the form of photons. Without being too technical, what you really need to know is that LEDs are more efficient at converting energy into light than incandescent and fluorescent models. LED lights to consume less energy, last much longer, and don't generate as much heat as traditional photographic lights, for example.
Built-in LED lights allow you to achieve a slim profile that is 1/2′′ thick. Today, more and more light bulbs are using built-in LEDs. LEDs are permanently embedded in the lamp, unlike devices with removable LEDs. The advantage of ergonomic LEDs is that they allow lighting manufacturers to create slimmer, more elegant luminaires. With a thickness of less than 1.5 cm, these innovative LED models can be installed in places where no other luminaire can be used. For example, many LED users like to install them to highlight art, and all modern photo lighting is based on LED lighting.
So how long do LEDs last? long time! Most LED lights typically last between 25,000 and 50,000 hours. For comparison, a typical incandescent lamp lasts about 1,000 hours, with a maximum of 2,000 hours. LED lighting does not burn out like conventional light sources; Instead, it slowly fades over time. Often, when buying an LED, you will see the inscription “50,000 hours at 70 percent” (“L70”). This means that you can expect your LED lighting to last at least 50,000 hours when it is at least 70% of its original power (less than 30%). The long lamp life coupled with the low energy used to create the light is what makes this technology so promising.
One of the best things about LED technology is that it allows you to create your own custom lighting design using different color temperatures, brightness, heat, and efficiency.
Correlated Color Temperature (CCT)
Most LED luminaires offer a choice of color temperatures with different shades of white. This temperature, or CCT, is measured in degrees Kelvin (K) on a scale from 1,000 to 10,000. The higher the Kelvin level, the closer the lamp's color production is to actual sunlight. Warm eggs usually have a temperature of 3000 K or less, while neutral eggs usually have a temperature of 4000 K. Temperatures of 5,000 K and above on the Kelvin scale produce "cold" white light. The Kelvin temperature of commercial and residential light bulbs is typically somewhere between 2500 K and 5000 K. It's important to consider color temperature when choosing lighting fixtures so that the look and feel of the light match the mood and atmosphere you're trying to create.
Color Rendering Index (CRI)
The CRI meter has gained popularity as LED lights are becoming more and more widely used in homes. CRI goes hand in hand with color temperature in choosing the right lighting for your application. Basically, CRI is an assessment of how well a light source renders the colors of objects in their natural form. Think of it this way: In today's social media world, we're used to seeing things displayed through various filters and apps that change the appearance of an object or item in real life. The purpose of CRI is to remove filters and display colors accurately as they are, from artwork hanging on the wall to food being prepared in the kitchen. On a CRI scale of 1 to 100, LED light sources with a CRI of 90+ are considered to be the best in terms of color reproduction. The higher the CRI, the more accurate colors will appear under LED illumination.
Luminous Flux and Power (Watts and Lumens)
When shopping for LED lighting, you often see lumens and watts used together. For example, Lm/W = Lumens per watt. Many people think of the watt as a measure of light output. It is actually the number of lumens used to measure the "perceived strength" of light. The higher the lumens, the brighter the light appears. A watt is a unit of electrical energy that measures how much energy you use, which is what you pay on your utility bills.
Lumens per watt is an important consideration when purchasing LED lighting. For example, a given LED bulb can only consume 9 watts and deliver 1,000 lumens. At the same time, an equivalent incandescent lamp consumes 100 watts to produce the same number of lumens.
