Light Emitting Diode Lamps
How are you able to connect a 9V battery to a regular household incandescent light bulb with p/n copper wire?
I am doing a science project, but I don't know where or how to connect the positively-charged and negatively-charged copper wire onto an incandescent light bulb (that usually goes into lamps). I am able to do it with a light emitting diode, but I can't seem to find out. If you could tell me, I would greatly appreciate it. 
There are two connections on the cap.
If it is a screw cap the screw is one and the lead dot on the end is the other.
If it is bayonet there are two lead dots on the end, the cap does nothing.
A 9volt supply will do nothing for a mains bulb and it does not matter which way round the neg and pos go on an incandescent bulb.
These bulbs are made to run at mains voltages so please do NOT try it with mains, unless you know what you are doing you will kill yourself.

Polymer Light Emitting Diodes Based on Polyfluorenes $138.61 This work is devoted to the study on Polymer Light Emitting Diodes (PLEDs) based on polyfluorenes, a promising class of semiconductive polymers for lightemitting diode applications. It covers theories of PLEDs, literature overview of polyfluorenebased lightemitting diodes, as well as research results by the authors. In this study, several types of PLED devices based on neat polyfluorenes or polyfluorene blends were designed, fabricated, and characterized. The electrical characteristics of two neat polyfluorenes were simulated via using space charge limited current theory for the holeonly case and/or exploiting a commercial software package.

CarbazoleBased Emitting Compounds $141.79 Carbazole is a heterocyclic tricyclic aromatic organic compound consisting of two sixmembered benzene rings fused on either side of a fivemembered nitrogencontaining ring. A large number of carbazole derivatives have been designed and synthesized and organic electronic devices based on these derivatives such as organic light emitting diodes (OLEDs), have been investigated. The optical and electrical properties of carbazoles are affected by substitution on the 2, 3, 6, 7 and 9Hpositions. Many carbazole derivatives have sufficiently high triplet energy to make them an efficient host where they can serve as red, green, or blue triplet emitters. Highly fluorescent and stable carbazolebased compounds were synthesized and characterized. Substitution of carbazoles at 3 and 6 position by tertbutyl group enhanced the solubility. Suitably susbtituted carbazoles form highly stable fluorescent organic nanoparticles. The emission of these nanoparticles was reversibly switched on/off in the bluegreen and orangered regions from a change in the ratio of the tetrahydrofuran/water system used in their preparation.

EDISON Power LEDS (Light Emitting Diode)
Led Lighting: Costlier But Better
The LED Lighting consists of the solid state lamps that use the light emitting diodes as their source of light. In this system, multiple diodes are used to make one light because the light produced by a single diode is insufficient when compared to any other incandescent or fluorescent lamps. Though the initial cost of installing the LED lighting system is higher than any other traditional systems, LED can be relied upon for its efficiency and long life.
The LED lighting system though costs you a little more, but will prove to be your long term investment. The facts that make the LED lighting better than all the other existing systems are:
- Efficiency: The efficiency of the LED is much higher. The LED can offer over 100 lumens from a device having the power of 1 watt. Furthermore, it is attuned in generating higher outputs at high driving currents.
- Size: Good things come in small packages. The LED lamps are the perfect example to this. The small size of the LED lights makes them flexible. They can be easily installed in form of rows, or at individual points, clusters and rings.
- Durability: Unlike the fluorescent tubes, these lamps do not have any filament or tube that can break, hence making the lamp durable and long lived.
- Life Expectancy: The LED lamp can produce non stop light for not less than 60,000 hours!
- Dimming: The LED lamps have an added advantage. They use the technology called pulse width modulation, in which the light gets turn on and off at varying intervals, thus providing full dimmability.
- Eco Friendly: The absence of mercury and hazardous halogen gas makes the LED lighting system Eco friendly.
But this magnificent system has its drawbacks too:
- The manufacturing process of the LED lighting system is still not efficient enough to meet the widespread requirements.
- The LED lighting is quite expensive as compared to the existing systems.
- The long life of the LED lamps poses threat to the bulb makers whose existing consumers invest a lot in frequent replacements thus contributing to their business.
