An effective high-efficient LED headlamp freeform lens design method is introduced in this paper. A low-beam lens and a high-beam lens for LED headlamp are designed according to this method. Monte Carlo ray tracing simulation results demonstrate that the LED headlamp with these two lenses can fully comply with the ECE regulation without any other lens or reflector.

A standard seven segment LED display generally has eight input connections, one for each LED segment and one that acts as a common terminal or connection for all the internal segments. The Common Cathode Display (CCD) – In the common cathode display, all the cathode connections of the LEDs are joined together and the individual segments are illuminated by application of a HIGH, logic “1

Generally, an LED is considered High-Power if it can dissipate 1 Watt or more of power. These are the fancy LEDs that you find in really nice flashlights. Arrays of them can even be built for spotlights and automobile headlights.

The luminance of a surface source (i.e. a source with a non-zero light-emitting surface area such as a display or an LED) is the ratio of the luminous intensity emitted in a certain direction (measured in cd) divided by the projected surface area in that direction22.

There is another factor underlying the improved perception of light from high CRI LED lamps. Below is a diagram showing the relative luminous efficiency of different wavelengths of light. Thus, cones have maximum efficiency at about 550 nm (green light)while the efficiency of rods is at its peak at around 510 nm (blue-green light).

High Kelvin lighting (greater than 3000K) create a harsh glare, making it difficult to see clearly at night. It can also suppress melatonin production, leading to disrupted sleep and other health risks. 3000K and less LED lights are the safest LED currently available.

How To Buy LED Bulbs for Your Home Lighting your home or business comprises around 15% of your overall energy bills. On average, $200 is spent each year to light your home. These numbers may not seem like a lot, but consider this—you can cut that expense
