LEDs are the latest lighting technology and have some advantages over incandescent lamps and CFLs (compact fluorescent bulbs.They also have some drawbacks, most of which are constantly improved by LED bulb manufacturers.However, many believe that they are successors to incandescent and CFL bulbs, as they use less energy and last longer than these two bulbs.Traditional incandescent lamps consume as much energy as heat, wasting 95%.Therefore, the efficiency of incandescent lamps is very low.CFLs is much better at converting the energy consumed into useful light.Compared to incandescent lamps, CFLs are about four times more efficient than incandescent lamps, wasting 80% of their energy as heat.This is better, the 80% may look very high, but keep in mind that the energy used by CFLs at the beginning is much less than that of incandescent lamps, and more energy is converted into light.Now, LEDs usually use less energy than CFLs, and it's hard to get average efficiency on them.LEDs are semiconductor or electronic components.Over time, their efficiency has improved, doubling every 36 months.This is similar to Moore's law, and LEDs have their own Moore's law, called Heinz's law.This law has been consistent since 1960 seconds when the led is just an electronic indicator (power or status light.The efficiency of LED bulbs has been close to CFLs in the past few years.This means that they currently exceed the efficiency of CFLs, and as long as haitz's law is established, the efficiency of LED bulbs will be twice that of CFLs in a few months.Mercury is known to be harmful to human health.Most people also know that CFLs uses mercury to make light.This may be a small number, but it is risky to use CFLs in lights around children or easily knocked down.This also complicates the recovery process of burnt CFLs.At present, the recycling center only accepts uninterrupted CFLs.While keeping in mind that typical tuna sandwiches have more mercury content than a single CFL, Mercury is not good for human health regardless of size..LEDs do not contain mercury because they are solidStatus electronic equipment, does not contain heavy metals such as moving parts, gases or Mercury that make it work.Therefore, if they are used around children or in lamps with the risk of being knocked down and damaged, they are safer than CFLs.Because of this, the led can be recycled, broken or not broken.Because the LEDs are very efficient and have always become more efficient, they consume less energy as heat and more energy are converted into useful light.It is very beneficial in a warm climate, especially in summer.The reduction in heat generated by light sources in the home, which means that the workload of air conditioning or HVAC system processing is reduced, by reducing the cooling demand, making the indoor climate of the home more comfortable and saving more energy.While the led still emits a certain amount of heat, it is still well below the amount of heat emitted by incandescent lamps, which also makes them safer around small children.Small fingers like to explore and touch, making it possible for them to burn on hot bulbs that are within reach.LEDs are warm but do not burn to the skin.We know that LEDs are solid.Instructions for electronic devices, they do not have moving parts or gases.Therefore, led can be many times longer than incandescent and CFL bulbs.Most manufacturers claim that their bulbs will exceed 25 incandescent lamps or 5 CFLs.This makes the led ideal for replacing bulbs in hard-to-reach areas and fixtures.Therefore, depending on the usage mode, the led may not need to be changed in about 20 years (if not more.You will see burned out like a normal incandescent lamp or a CFLs.The typical failure mode of the Led is to darken slowly over time, fading to 70% of the original brightness at the end of the expected life.That said, they don't fail completely once they disappear, it's just where they should be replaced, even though they still work.In fact, they are, but the cold temperature will have a positive impact on their life expectancy, and depending on the temperature, it will increase the light output to a point.This makes the led suitable for use in refrigerators and freezers, which the supermarket found to be a huge investment and realized could save a lot of energy and human capital from burning out tube lights without replacing the ledWhen it comes to fluorescent lamps and cold temperatures, if you ever turn on CFL installed in outdoor fixtures on cold winter nights, you know that CFLs are very dim at cold temperatures, if any, it may take quite a long time to warm up to full light.Led no preheating-The rising cycle like CFLs, no matter how cold, can be opened with full light.This makes them suitable for use in a cold climate where full brightness is required for safety reasons.The cost of the led has dropped rapidly over the past few years and continues to decline.However, the cost of a single bulb still exceeds that of a single incandescent lamp or CFL bulb.This makes most consumers ignore them when they buy new bulbs.Their high cost makes it expensive to replace many bulbs at home.However, their long life and reduced energy consumption over time exceed the increase in the initial cost.Since most LED bulbs allegedly can use 25 incandescent lamps and 5 CFLs, the cost of purchasing a single bulb of any type to match the life expectancy of the LED bulb can be considered a saving.This offset the cost of the bulb, allowing the reduced energy consumption to be paid over time for the rest of the bulb, eventually earning a positive return as an investment.If you 've seen or dealt with a retail LED bulb that sells a replacement for 40-watt and 60-watt incandescent lamps, then, you may have noticed that most LED bulbs are made of some kind of metal, it's usually aluminum.The reason for this is to dispel the heat generated by the bulb.If this heat is allowed to accumulate around the bulb and cannot dissipate effectively, the expected life of the LED bulb will be shortened and due to the distortion of the circuit board to which a single LED is installed, it could suffer a catastrophic failure.The radiator built in the LED bulb body is very effective in keeping the bulb cool and working temperature range.However, there are a number of fixtures where LEDs are not suitable for use, such as embedded ceilings or sealed fixtures.Even if there is a radiator, the LED bulb installed in this fixture will overheat, because the heat emitted by the bulb has nowhere to go except to immediately enter the space around the bulb.This may cause the heat problem mentioned above.Therefore, the led is excellent for lamps and fixtures that are not sealed and have good airflow.The radiator used by the LED bulb for heat dissipation increases the weight of the bulb.This makes them heavier than incandescent lamps and most CFL bulbs.Therefore, some lamps, such as curved table lamps or other lamps with flexible or adjustable components, may be affected by this increased weight.This can make them drooping or falling from the weight (in the case of a small desk lamp) although this can only happen on a lamp made of cheap parts or a less robust soft lamp neck.Therefore, before LEDs become more efficient and generate less heat, and are able to dissipate heat with smaller, lighter radiators, they are more suitable for more robust lamps that are not flexible or adjustable.Most LEDs glow in a fairly consistent mode in a beam that goes straight out from the top of the bulb.The light emitted by early LED bulbs is very similar to the light emitted by the flashlight, in a beam that spreads less well.This makes most LED bulbs only suitable for use as spotlight or decorative focus lighting, with few others.However, the manufacturers have made great improvements in this regard, adjusting the design of LED bulbs to make them more similar to incandescent and CFL bulbs in the way they glow.This greatly improves them as light can be emitted in a wider range.In a typical desk lamp, the old led bulb emits most of the light to the top of the lamp, and there is no below.The light emitted by the newer bulb is more uniform, and more light is headed down or towards the bottom of the bulb, which is typical.The change in bulb design, each generation of LED bulbs has improved a continuous process on this basis.Will the Led be as good as an incandescent lamp?In terms of most intentions and purposes, led is already a good alternative to incandescent lamps in several applications in the home.Night lights can be replaced with cheap low-power LED bulbs that will last for years.Reading, wardrobe, appliances such as refrigerators, and desk lamps are ideal for using higher wattage LED bulbs.In order to truly gain market share, the above shortcomings will be greatly reduced, but with incandescent lamps coming out soon, manufacturers will invest heavily in the development of better bulbs.With the introduction of haitz solar Law, future LED bulbs will produce less heat and more light, resulting in brighter bulbs that consume less energy.
