All the benefits of LED lamps
The LED generates virtually no heat and can use all of its electrical energy to light.
A strong light output can be generated in a very small space, which allows to miniaturize the torches or lamps and keep a light to incredible power.
The electric charge influences the level of energy in the diode, causing the production of light. Depending on the type and the combination of semiconductor materials using, the wavelength of light, and so the color of the LED can be controlled.
Luminous efficiency of an LED and an incandescent bulb
Your flashlight you used to light or heat?
Energy consumption and light output of a lamp are two completely different things.
Conventional bulbs transform electrical energy into electromagnetic radiation. Only part of this translates into a visible light radiation. Most of the energy is released as heat radiation long-wave (infrared) generating no light, only heat. Unfortunately, it’s the same for the LEDS produced low-cost containing impurities.
LED LENSER, uses for its flashlights or frontal LEDS of high quality (NICHIA or CREE) that illuminate better, do not heat and use less energy
How does a LED lighting?
The LEDs (Light Emitting Diodes) are electronic light sources based on what is called semiconductors, for example gallium, Silicon, or arsenic. For high luminous efficiency, they must be absolutely pure and must comply with certain requirements. To achieve this goal, a very thin semiconductor base layer (wafer) is placed in a Chamber under vacuum and covered with a molecular layer. This process is called (by molecular jet epitaxy) MBE and can also be described as the growing crystals.
After implantation of atoms of impurities in pure crystal structures, the slice is cut into microscopic sized units. These semiconductors together the different poles (anode and cathode) and are then a light chip.
The light-emitting diodes are strong and completely resistant to shocks microstructures. They last up to 1000 times more long conventional bulbs, put halogen bulbs far behind, does that extremely little heat and consume less power. LEDs contain no harmful filler gas and emit no ultraviolet light.
LUMEN, LUX & CANDELA: the key terms of the technology of light
Luminous flux, illuminance and light intensity, how do you measure the performance of a flashlight or front lighting?
The luminous flux is refers to the amount of light emitted.
The luminous flux is calculated lumens (lm)
The luminous flux is the main indicator to measure the performance of a lamp
There the amount of light or light energy that is actually emitted by a light source.
Some manufacturers indicate the luminous flux of the LED bulb or incandescent and fail to indicate that it is considerably reduced by losses in the head of the reflector/lamp (sometimes more than 30%). Our luminous flux values are values measured with spectrometers, on lamps equipped with new alkaline batteries.
The illuminance refers to the illuminated area.
Illumination light, expressed in Lux, corresponds to the intensity with which the surface is illuminated. It originated with photography.
The illuminance is with a photometer.
With our advanced development ([Advanced Focus System]) and system dynamic adjustment ([Switch dynamic]), you can adjust the light intensity to your needs. Lighting that is too strong on a map, too low or no homogeneous on a rocky path in strongly reduced its accuracy.
1 lux (lx) corresponds to a luminous flux of 1 lumen (lm) evenly covering 1 square meter (m2) is: 1 lx = 1 lm/m2
Light intensity measures the strength of the beam
Light intensity, measured in Candela (cd), depends on the luminous flux (amount of light) and the angle of the light beam.
Despite a quantity of light produced identical, the brightness of an LED on an angle of 10 degrees is more than 130 times greater than a led light is distributed on an angle of 120 degrees. This is due to a much wider angle.
LED 10 degrees is so more suited to illuminate more remote areas, while the 120-degree diode lends itself to proximity lighting.
This light is perfectly adjustable on LED LENSER lamps with the advanced focus System Advanced Focus System.Adjustment is made in Flash.
