What Reveals The Angle About The Magnitude Of (Led) Lamps

Since the 01.09.2013 light means packaging full of information. But really help to find the right light source among all the possibilities? In our new series of articles, which begins today with the topic of beam angle, we turn to the parameters that are understood not readily and show that they are responsible for what visible differences.

The Angle When Directed Light Sources

The beam angle (or half value angle) is an important criterion to determine how well an LED lamp illuminates area and how much their eyes if necessary. With his value of degree of, he reveals: how wide is the leg of the light a lamp.The light beam is the beam or just the glow of light, emits a light source in different directions.Where “the smaller the angle, the bundled and intense the light.” The greater the angle, the more surface is lit.”

You can tell from the angle so where most of the light is going and see the degree range, in which it gives off at least half of their maximum luminous intensity LED. Outside of the beam angle, there is of course still flareso it is around not completely bleak. In the Streulichbereich the lamp reaches at least 10% of their maximum luminous intensity. Only outside of the so-called “cut-off angle”, it is completely dark.

The Radiation Characteristics Of The Various Types Of LED Lamps

Since the angle is related to the shape of the lamp body , it varies from type to type.

LED Spots have a rather narrow beam angle of 30 ° up to 120° degrees. The smaller the angle, the spot light and better illumination of glass cabinets etc..

LED bulbs give off light in almost all directions . Their angle moves in the range of 60° to 360 ° degrees. Thus, they can replace completely the old bulb in the truest sense.

LED tubes have different beam angle, depending on the type. T8 tubes there are degrees with a half value angle of 90 ° to 240 °. T10 LED tubes are there even with 360 °, where both types of construction with conventional fluorescent lamp versions (G13) are compatible.

LED panel provide maximum light output for pleasant, glare-free light with a beam angle of 120° to 160° degrees.

LED Strip typically has a beam angle of 120 °. The light there is, where it to go, the correct mounting is important so that E.g. not 80% of the light output of the ceiling are covered and you can see only the scattered light. Also applies, the more SMD LED on the band are, the brighter the LED stripe light.

…Und Of Here At Last Even A Few Points Of Reference:

LED suitable for the illumination of corridors and paths in the Interior with an angle of 90 °.They serve as basic lighting, light sources should have an angle of at least 120 °. Also thedistance to the coverage area plays a role, so an angle enough for hanging lamps of 180°, while it should be already 300 ° Rotary Beeding when lying or standing position for a good illumination.

Tip from franciscogardening.com: No angle is indicated on the packaging you better access to one other LED bulbs so no nasty surprise awaits you at the coverage characteristics.
