The presence of electric light - a necessary condition for ensuring the comfort of modern living.
In recent years, the sale of two new types of bulbs: energy-saving and LED.
Their advantage over incandescent light flux is caused not afford due to luminescence incandescent spiral and using luminescence (energy-saving products) or luminescence p-n-transition (LED). These lamps have similar dimensions and are convenient to use because they are utilized for connection of standard cartridges of lighting devices, see Figure 1.
The presence of two competing species lamps poses a consumer choice issue. Usually it is solved by comparison, and to increase the validity of the draw a few criteria.
Power consumption, efficiency, luminous efficiency and emission naturalness
Both types of new types of lamps are more expensive than conventional incandescent lamas, and the benefits from their use is considerably lower power consumption, wherein at least the rising cost of electric power value of this factor will only grow.
Electrical power LED (LED) lamps with equal intensity of the luminous flux given off by about 1.5 times less than in the energy saving. Accordingly, it is also higher overall efficiency.
Additionally LED light source provides a higher light output and a better match of the light emitted natural light.
For luminescence effect in household energy-saving lamps need to use a few milligrams of mercury, which is a strong poison. For this reason, the waste of the variety you need to take the lamp for disposal in a special collection point.
LED light is environmentally friendly, in case of failure it is possible to just throw in the trash.
Budget "energosberegayki" are created on a primitive start-up regulator that leads to flickering of the generated light. his eyes did not notice, but medical studies have shown its pronounced negative effect on the overall psychophysical condition of the person.
In contrast, the LED lamp mechanism functioning such that its flicker radiation can not appear, in principle, regardless of the level of technical solutions used and, accordingly, value.
LED lamp during operation remains cold, serviceable luminescent heated to about 50 ° C. When it is a failure or failure of a control unit in the latter case, the temperature increases considerably. Fortunately, due to the high operational reliability of this rarely happens.
De facto, given the relatively low operating temperature of the energy saving lamp it should be recognized equivalent LED.
The manufacturer can give a glass flask energy saving lamps different shape. Widespread, e.g., spiral bulb, Figure 2.
This allows the use of such lamps as part of the room decor.
In contrast, the LED lamp looks generally do not differ from the traditional incandescent lamps with a spherical bulb, Figure 3.
The overall result of the comparison for the most important parameters for the average consumer was in favor of LED light bulbs. Therefore, it should be seen as the main source of lighting facilities.
Opt for energy-saving fluorescent lamp is suitable only when they work short period of time (this allows you to compensate for their lower efficiency), or used as an element of decor premises.
