Today the main concern of many homeowners is the electricity consumption of a lighting system. The
high cost of power is uncontrollable and nowadays the best option of
private households is to use energy-efficient lighting. Other factors that may affect the decision on the choice of the lamps are environmentally friendly features. We are always concerned about the pollution in our environment, and it is time that we choose environmentally friendly products.
In the past, the types of light bulbs, which are frequently used, the incandescent lamps, which have been developed in the halogen species. This was the same principle. The bulb has been improved and updated to the halogen lamps, which we will use. Innovations had introduced a new technology in lighting and we now have the LED lamps.
LED stands for "Light Emitting Diodes". Since it is energy efficient, it was the best alternative to halogen lighting. When comparing this new technology for the halogen lamp, there are a number of factors to consider. Here we will explore the various advantages and disadvantages of using each of the halogen and LED
How They Work - In the halo, the current tungsten filament heated to emit light. In the LED version, light is generated when an arc of electrical current between the electrodes of the lamp extends.
Energy Efficiency - With the use of LED used, your energy savings amount to 75% of the power in the halogen bulb. These lamps do not produce a large amount of heat and as a result you will be as little as 2 to 10 watts of power to require it functional. The halogen bulb produces enough heat that makes them consume more energy.
Cost-Effectiveness - The cost of the LED bulb may cost more than the halogen bulb. Due to the longer lifetime of the lamp, it is less expensive. In addition to its cost from the amount used to radiate energy to light up the bulb.
Longevity - The LED type can be effectively used for 50,000 hours, while the improved incandescent type lasts only 6,000 hours. Thus, it takes 8 halogen bulbs to LED life one way in which a 8:1 equal.
Heat - A very remarkable disadvantage in the improved filament lamps, the amount of energy that is converted into heat. When a halogen lamp is switched on 90% of the energy is converted into radiant heat, which corresponds to heat. The majority of the energy in form of heat and light, which does not make this less desirable than the counterpart electrode. The LED is very little heat is produced and most of the energy is in abundant supply with light.
Light intensity - Both types can produce about 20 lumens per watt performance. Lumen is the unit of luminous intensity.
Dimness Feature - This is where the halogen has an advantage over the other. You can generate the halogen light dimmer in a place and in the process is to produce a good performance. The more expensive LED type is weak to a low 20% light output. There are kinds of LED lamps, which would not even be on a dimmer function set-up.
A comparison of halogen and LED lamps that there is good reason to believe that the use of the latter type is more useful or beneficial. Since there are kinds of laser lights available in the market today, why do not we take a look at the features of this lighting system? In search of better light, we can see a serious competitor of the LED.
First is to explore the nature of light produced by a laser variety. Projecting the laser light in a single narrow beam, and so that it illuminates only a small area. The laser delivers a specific wavelength or visible light. The color of light generated by the laser as a function of this wavelength. In the LED light is generated when current flows through them electrodes. When the laser light is generated when electric atoms causing the release of energy.
The laser can be used to advantage as, at least more than incandescent types, but it has its greatest drawback. The intensity of the light from the laser beam that can damage a person's eyes, to the extent of loss of vision....
