2. LED circuit - Wikipedia

   en.wikipedia.org/wiki/LED_circuit

   Simple LED (Light Emitting Diode) circuit diagram. In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.

3. Voltage converter - Wikipedia

   en.wikipedia.org/wiki/Voltage_converter

   A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...

4. Multifaceted reflector - Wikipedia

   en.wikipedia.org/wiki/Multifaceted_reflector

   The same is true of MR11-compatible LED lamps. Fixtures designed for halogen MR16 or MR11 lamps that use electronic transformers may need to be retrofitted with LED-compatible transformers. There is a wide variety of designs, varying significantly with regard to beam width, light colour, efficiency and luminous power.

5. Power supply - Wikipedia

   en.wikipedia.org/wiki/Power_supply

   A very small low-power dummy load such as a ceramic power resistor or 10-watt light bulb can be attached to the supply to allow it to run with no primary load attached. The switch-mode power supplies used in computers have historically had low power factors and have also been significant sources of line interference (due to induced power line ...

6. Holiday lighting technology - Wikipedia

   en.wikipedia.org/wiki/Holiday_lighting_technology

   Holiday lights of this type do not suffer from color fading because the light is determined by the LED's chip rather than the plastic lens. White LEDs are similar in most respects such as power and durability, but utilize a two-stage process to create the white (polychromatic, or broad spectrum) light.

7. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   One-color light is well suited for traffic lights and signals, exit signs, emergency vehicle lighting, ships' navigation lights, and LED-based Christmas lights Because of their long life, fast switching times, and visibility in broad daylight due to their high output and focus, LEDs have been used in automotive brake lights and turn signals.
