What type of light bulb uses phosphors?
fluorescent, LEDs
Make a list of the uses for leds?
LEDs are used in traffic lights, on computer lights, car lights and indicators. You can also purchase LED flashlights and torches. Can be used in small devices for a variety of uses.
What device uses LEDs and photo diodes for ignition triggering?
optical triggering device
What are some every day uses of LEDs?
Rechargeable flashlights. Some TV's. A wrist watch.
How do you connect 5 LED rebel star?
Have a common ground and separate the +ve to each of the LEDS
Which is a more powerful light - 95 leds or 128 leds?
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
Which fiber-optic media type uses light-emitting diodes LEDs instead of lasers?
Multimode fiber (MMF.
When to connect LEDs in parallel?
Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.
What can a L.E.D light be used for?
LEDs have many practical at home uses as well as military uses. The leds at home can range from car headlights to emergency self defense lights or simply LED bulbs that can replace your old ones. Since LEDs are more efficient while bring more light they can cut down on power bills. Then you have people who need them for high stress situations such as police officers and military personnel. There are lights that can reach up to 1/4 of a mile on single batteries.
What are the uses for LED?
The Major use of LEDs until recently has been indication. For Example: Power Supply Indication, or Process or progress Indication etc. In recent years, the light outputs from LEDs has grown and they are becoming common as lighting fixtures. They tend to be much more efficient than tungsten or fluorescent lighting and give off very little heat. In large scale video applications, they are used in open air television screens. The increase in light output possible with modern LEDs mean they are well suited to imaging applications in high light areas such as open air concerts. Another very common but little noticed application is in remote controls. Infra-red LEDs are used to transmit signals from remote controls. Although the light is invisible to us, the communication medium is entirely optical. LEDs are also capable of emitting ultra-violet light, another part of the spectrum that is invisible to us.
How many colors do LEDs come in?
red, green, yellow, blue leds
Are colored Christmas tree leds the same as the leds used in grow lights?
No.
