Led Camera Light
Infrared LEDs to light room for camera?
I have ~10 infared LED’s hooked up in a circuit to a dc power supply. When I look at these LED’s through a video camera (while the LED’s are on, of course), I see very dim light; not enough to light the space I need it to. I can brighten this light by upping the voltage, but am worried that i may fry them. What is the best way to set these up? in a series, or parallel? what voltage should I use? are these enough LED’s? i only need them to light up a closet size space.
There are a few numbers:
Reverse Voltage (VR)-5 V
Forward Current (IF)-100 mA
Forward Voltage- 1.5, 3.0
what voltage is it? and does this mean I must have 100mA for each LED i put in the parallel circuit?
Find out what the maximum voltage for these particular LED’s is and use that. If you have a variable power supply just hook them up in parallel. The only reason to hook them in series would be to adjust to a fixed voltage supply.
It might be interesting to try UV LED’s for this venture as well.
LED Lights and Their Growing Demands
<!– @page { margin: 0.79in } P { margin-bottom: 0.08in } –>
In present days lights are becoming smaller and much more efficient as well as quite less power consuming. LED lights are such lights those are gaining popularity all over the world for their most exciting features and flexible use. These lights are very small in size and offer tremendous amounts of lights comparing with their size and shape with other contemporary available lights. The intensity of each LEDs aren’t sufficient to make bright luminary light that we use in household or office compared to commercially available lamps such as incandescent & compact fluorescent lamps; but multiple LEDs are to be used together for making lamps, which is named as LED lights.
Now-a-days the diode technology has been improved so we can produce high power LED lamps whose intensity is higher. The commercially used LED lamp of 100 watt emits 7527 lumens, 7.527 lm/W (unit of intensity of light) which are brighter than incandescent lamps. The LED lights are replaceable with the conventional compact fluorescent & incandescent lamps. But there is a little problem in this replacement. The problem is that the diodes work only with direct current (DC). So we have to keep in mind that the LED lights do not withstand with AC. This purpose can be served by using a rectifier circuit internally. At a high temperature LED lights break down so it is important to include heat sinks or cooling fans in LED lights to ensure better performance as well as longevity. The initial cost of LED lamp is very high compare to fluorescent lamps or incandescent lamps. These lamps offer 30,000 hours of lifetime which is highest among incandescent lamps which offers 1,000 hours and compact fluorescent lamp which offers 8,000 hours of lifetime. These lamps can last up to 25-30 years approximately. Throughout its lifetime the LED lights offers brightest illumination among any other conventional lights present in market. These lights are mercury free and available in various colors. As the lamps are mercury free so ultraviolet can not be generated from these lamps.
Automotive (cars, bus and truck), locomotive (train) & bicycle lighting are the main practical area of application of LED lights. These lights are used in both as headlights of the cars, trucks and train as well as inside lighting of those vehicles. Because of flexible mounting capabilities & vibrant color, people use these lights as showcasing details to accent parts of their bikes and cars. For better illumination and low power consumption the LED lights are taking place in household, now-a-days. Billboard is the advertising board where we need power for whole night. If we use LED lights for this purpose that would make our power consumption low. Christmas lighting can be done by LED string lights which save electricity bills. LED flashlights are very effective for handy cams or cameras. As we know cameras and handy cams flashlights need extra batteries to make flash so in the case of LED flashlight power consumption of the battery remains low compare to the conventional flashlights.
