Incandescent Bulb The Higher The Power, The Higher The Bulb Brightness

Incandescent Bulb 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, if there is 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 light bulbs, connected to the insurance after the total switch, such as light bulb, to prove that the line has a short circuit or ground, and then sub-section of the branch; when disconnecting a road after the light bulb does not shine, To prove that the branch failure. Operation can be power consumption from small to large, respectively, after the separate appliances were closed immediately after the light bulb should be slightly off after the extinguished,Incandescent Bulb the greater the power the greater the brightness of the bulb, such as electrical appliances Power is greater than 200W, you can re-parallel light bulb at both ends of the original 100W, when there are short-circuit ground fault, the light 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 failure 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,Incandescent Bulb then the light bulb connected between the positive and the ground, then the light 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; if the fault point no obvious symptoms can be taken to check the short circuit, branch road section by paragraph The point of failure.

At present this new incandescent bulb exists only in theory, that is,Incandescent Bulb there is no possibility of listing in the short term.

Compared to traditional light 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,Incandescent Bulb 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, only 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 light to the filament,Incandescent Bulb filament re-absorption of light after the conversion into electrical energy again light. This is the case, the 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 this theory into reality, they are still very confident.
