With many advantages over conventional lighting and fluorescent lighting, LED lighting is meant to replace all types of lighting. Choosing and buying LED lighting forces customers to learn new words and think about things they don’t have to think about when buying an existing type of lighting. This short paragraph provides general information and considerations for first-time buyers of LED replacement lamps. You can visit OPPNO for best LED!
As most of you already know, LED stands for Light-Emitting Diode. LEDs are true semiconductors (similar to computer chips) that produce better light than conventional lighting. When electricity passes through it, it releases energy in the form of light. These semiconductors are doped or impregnated with a chemical that determines their brightness. LEDs convert most of the energy transmitted by the LED into light, unlike incandescent lamps, which produce light from heating elements. As a result, LEDs can be up to 90% more efficient than household appliances.
LEDs have been widely used as indicators and warning lights for almost 40 years. But it’s only recently that experts have been able to figure out how and design general-purpose white LED lights. Due to the light and brightness of LEDs, LEDs are the first choice for car and vehicle lighting, brightness and reliability are important.
So what do you need to know when buying LED bulbs? The following list gives some basic tips.
1. Although the upfront cost of a lamp is still high, the total lifetime cost of the LED lamp is actually lower than the cost of equivalent incandescent and CFL bulbs. Considering the cost, time and resources required to replace batteries and CFL bulbs, LED bulbs that last up to 80,000 hours have a lower cost and longer life.
2. LEDs are versatile – many types aren’t as cost effective as lighting because it’s so easy for unlucky customers to find the right path. High-end LED chips emit light with a color rendering index (CRI) of 85%. However, CRI is a general-purpose measure of light’s ability to accurately reproduce the colors of various objects when compared to natural or natural lighting. LED bulbs that use the best LEDs last longer than new bulbs that many people sell, and 60% longer than many incandescent bulbs that use non-standard LEDs.
3. Unlike some readable parts, LEDs generate electricity, and this heat is the biggest problem that manufacturers face when developing LED lighting. Manufacturers are now able to design individual LED chips that shine as bright as 100 watt incandescent bulbs, but installing LEDs in kits is not a good idea for lighting because it creates problems without ventilation. LEDs installed in fixtures and bulbs must have good ventilation, and the better the chip, the more difficult it is to cool properly. If this is not taken into account, there are many LED lights on the market that use cheap chips that do not require ventilation or do not blow properly, which shortens their lifespan. Normally, LED bulbs are not very hot to the touch, but they can fail prematurely if the chip is malfunctioning.
4. LED bulbs last longer than conventional bulbs, but pay close attention to the manufacturer’s claim for lamp life. The life of LED lamps should be “half-life”. LED bulbs do not burn out. Instead, it slowly fades away. When the supplier claims that the LED light will last up to 80,000 hours, it means that at that time the chip has reached 50% efficiency and the lamp needs to be replaced. So the lighting can last more than 100,000 hours, but during this time the efficiency will decline. Therefore, using the 100,000 hour lifespan as an eye can be confusing. Although LEDs are not permanent, they last 50 to 75 times longer than incandescent lamps and 6 to 8 times longer than CFLs.
5. Browse the website, and you will quickly see that the LED lighting industry has gone through the market. Many of these lights are relatively inexpensive (under $20). However, you will find that many of these LED bulbs are made from unreliable materials with poor performance. High quality LED bulbs cost more than those cheap bulbs because they use high quality chips at a stable price from reputable companies like Cree. This means that these LED bulbs are more expensive, but better.
6. LED bulbs cannot be dimmed with conventional dimmers. LEDs need a constant current to operate. Therefore, if the standard dimming method is used, it will flicker during a temporary or single failure under severe conditions. Dimming LED lights requires a 0-10V dimming module which “tricks” the LED into emitting dim light. In theory, this module can dim any LED light.
7. When comparing LED bulbs, you need to understand lumens. The lumen is a standard unit that can be used to compare LED bulbs to incandescent and halogen bulbs. Basically, lumens is a measure of brightness. The quantity of lumens is important, but perhaps more important is the quality of the lumens, ie the luminous efficiency (lumens / watt). Today’s high quality LEDs have a luminous efficacy of 60-70 lumens/watt. 8. Color temperature and brightness are important tools for comparing LED lighting. Color temperature and spread are measured in degrees. The color temperature describes the color of the emitted light. Usually 3000 Kelvin is warm white (near infrared) and 5000 Kelvin is cool white (near ultraviolet). Cool white is brighter because it is the natural color of LED lights, but chips that emit warm white light must have a phosphor “filter” to “warm up” the color temperature, which reduces brightness of the chip. Beam transmission is the angle of the emitted light. The lower the number, the closer the light is to the “center”.
