What Is Mercury? Featured Video. Points: 8. The first replacement for the regular incandescent bulb is the compact fluorescent bulb. But today in the market the best available bulb is the light emitting diode LED bulb. If you compare the efficiency of these bulbs a As there is a chemical reaction involved in CFL the bulbs will get heated up very fast and a lot of energy will be wasted in this process.
Because of the above facts, a LED bulb will be having the following benefits, 1. More age. Less waste generation as bulbs will not fuse of fast.
No mercury hence less hazardous. Less carbon footprint as CO2 emitted is less. Very less risk of fire 6. The solid-state technology is used in making these bulbs. Hence less breakage. Less power consumption. As less consumption of power, electricity bill will be less. But some people say that initial cost is more but if you see the power bill and replacement frequency you can recover the extra cost in a very short time period.
The main reasons for less power consumption are. No chemical or chemical reaction is involved. No wastage of power in the heating up of the bulb. Points: 5. Depending on their theory of operation and design they have different efficiencies of these conversions.
In the traditional filament type bulbs, there is an enormous loss of electrical energy in heating the filament and only a small part of it is given out in form of light. In CFL due to gas ionization and more emission of light in the visible region, the efficiency is better and for the same light output less current is utilized which means less expense of electricity.
LED are semiconductor devices which are most efficient as regards to the conversion of electric currents to output light. They work on the principle of electroluminescence. These semiconductor devices use very small currents but give light in better proportion in comparison to the earlier filament type or CFL. Points: 4. CFLs produce light differently than incandescent bulbs. In an incandescent, electric current runs through a wire filament and heats the filament until it starts to glow.
In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating called phosphor on the inside of the tube, which then emits visible light.
This entire process typically takes 30 seconds to 3 minutes to complete, which is why CFLs take longer than other lights to become fully lit. CFLs with decorative covers like globe or reflector shapes have a unique design challenge that results in the tradeoff of a slower warm up time, which is why these CFLs take longer than bare spirals to reach full brightness. Older CFLs used large and heavy magnetic ballasts that caused a buzzing noise in some bulbs. Most photocells, motion sensors and electric timers are not designed to work with CFLs.
