How to determine the Angle of led mining lamp, street lamp?

We led mining lamp when the choose and buy, often asked about how much you use Angle led mining lamp, led mining lamp light Angle is what mean? And how should design the led mining lamp light Angle? There include the led light Angle, lens of

when we choose a miner's lamp, led industry we often asked you how much is the Angle of the miner's lamp with led industry, led industrial light Angle of miner's lamp is how many? How to design the led industry miner's lamp lighting Angle? Here including the side of the led light Angle, the influence of the lens of the light Angle, chimney, etc. The most important is the light Angle lens. Refers to the light-emitting diode Led Angle Angle, namely the light scattering Angle, mainly through the diode add scattering agent to control the production process. The lens is secondary light distribution. Lens Angle refers to the scope of leds products after blinking, the size of the beam Angle. Tunnel traffic lights will reflect the same light source the light spot size and intensity are lit on metope, namely the beam Angle is smaller, the center of the light intensity, the greater the light spot is smaller, the better lighting effect. Common beam Angle on the market at present there are 8, 15, 25 and 45, 60, 90, 120, can be divided into narrow Angle beam: 40. Led miner's lamp is usually wide beam, most is 90 degrees or 120 degrees, if you need to light intensity, some of them are 60 degrees or 45 degrees. Specific design should consider the installation height, parameters such as distance, intensity of illumination requirements to select. In addition, we can see from the appearance, the miner's lamp chimney actually led industry has a certain concentrated and adjust the function of the beam Angle. However, with some manufacturers in the production of industrial miner's lamp chimney is more and more bad, reflection and concentrating function is becoming more and more small.
