Incandescent Bulb Converted Into Electric Energy Again
- Jul 18, 2017 -

Compared to traditional Incandescent Bulbs, the advantages of LED bulbs is self-evident. Almost asserted that the future of LED bulbs will appear in every corner of our lives. LED bulb biggest advantage is energy saving, but its shortcomings are also very obvious, that is not "warm".

Is energy saving to reduce the heat of the bulb itself? The answer is definitely not the case. Recently, the Massachusetts Institute of Technology R & D team put forward a new solution. MIT developers have developed a new incandescent bulb, the bulb can absorb their own heat, and then turn these heat into electricity for its power supply shiny. After this cycle, this new incandescent bulb is more energy efficient than LED bulbs.

In fact, this new incandescent bulb does not change the traditional incandescent bulb principle, just in the bulb surface attached to a layer of crystal filter. The role of this filter is: after the launch of the light source, you can simultaneously reflect the infrared to the filament, the filament re-absorption of light after the conversion into electrical energy again. So so, cycle, until the lights closed so far.

But hear this, you are not too excited about the loyal fans of incandescent bulbs. At present, this new incandescent bulb exists only in theory, that is, there is no possibility of listing in the short term. However, the R & D team said that for the theory into reality, they are still very confident.

Incandescent lamp from the glass bubble, filament, lamp three parts. Filament with high melting point and not easy to evaporate the tungsten wire made of low-power bulb into a vacuum, high-power (greater than 40 watts) of the bulb into a vacuum, filled with inert gas, such as argon, Incandescent Bulb , There are two kinds of jack and screw type, the power of more than 300 watts of Incandescent Bulbs, generally use the mouth of the mouth, because the screw-type lamp in the electrical contact and heat dissipation than the socket-type lamp.

Incandescent light principle: incandescent lamp is the use of filament resistance current thermal effect (power conversion to heat), so that the filament temperature rose to the degree of incandescence and light (thermal energy into light), due to the evaporation of high temperature filament, after prolonged use In the incandescent glass shell is easy to produce deposits and black, so that the light transmission performance and reduce the impact of luminous efficiency, so incandescent light luminous efficiency is low.

There are many types of incandescent, according to the working voltage, there are 6,12,36, and 220 volts and other four, of which 36 volts are low-voltage bulbs for local lighting and carry lighting, in the installation of incandescent bulbs, pay attention to Incandescent Bulbs Of the operating voltage and line voltage must be consistent, if the mistake of 36 volts connected to the 220-volt line, due to the voltage is too high, the current through the filament is too large, will make the filament burned, on the contrary, if the mistake of 220 volts Access to 36 volts of the line, because the voltage is too low, the light will be no light to light.

Incandescent lamp in addition to the use of lighting, but also can be used to limit the current, light instructions.In addition, by the filament resistance to the positive temperature coefficient and other characteristics, but also in the electrical maintenance to play a lot of convenient and practical role, the following list:

1, find the circuit failure to single-phase circuit, for example, such as a short circuit or ground fault, the home switch will trip or burn insurance, then all the appliances should be turned off all the home in the main switch line A 220V / 100W or so Incandescent Bulbs, connected to the insurance after closing the main switch, such as Incandescent Bulb, to prove that the line has a short circuit or ground, and then break off the branch; when disconnecting a road after the Incandescent Bulb does not shine, To prove that the branch failure. Operation can be power consumption from small to large, respectively, immediately after the closure of the electrical appliances immediately cut off, the bulb should be slightly off after the extinguished, the greater the power the higher the bulb brightness, such as electrical appliances Power is greater than 200W, you can re-parallel Incandescent Bulbs at both ends of the original 100W, when there are short-circuit ground fault, the Incandescent Bulb will be very bright, and sometimes the point of failure will smoke or spark, so it is easy to detect the point of failure. Cable or overhead lines of the inter-phase breakdown or ground fault, can also be used to find a similar approach.

2, find substation control circuit failure in a special control power substation, short circuit fault can also be used to find the above method, but should choose the same level of control voltage bulbs (if necessary, in series or parallel way). For the ground fault, to DC, for example, if the cathode appears ground, put the two ends of the lamp connected to the negative side of the power supply and ground; such as the negative ground, then the bulb connected between the positive and ground, then the Incandescent Bulb With the size of the grounding resistance of the fault point and issued a different brightness of light, the point of failure may also smoke or a small spark; such as the point of failure without obvious symptoms can be taken to check the short circuit, branch road section by paragraph The point of failure.
