LED with different lighting Angle USES has different lighting Angle. Special luminous Angle, the price is higher. If all diffuse Angle, the price is higher. Life is different, the key to quality is life. Life is determined by light decay. Light decline, long life, high price.

No flash DC, good protection for eyes, is the best choice for lamps and flashlights.The LED, the heart of the LED, is a semiconductor chip with one end attached to a scaffold, one end of which is the negative pole, and the other end connected to the positive pole of the power supply, so that the entire chip is encased in epoxy resin. A semiconductor chip is made up of two parts, one of which is a p-type semiconductor, in which holes dominate, and the other of which is an n-type semiconductor, on which electrons dominate.

So how to identify LED display light bead pros and cons? First: Look at the brightness, is usually referred to as your lamp bead can reach how many LM(lumen), LM(lumen) is a measure of the lamp bead brightness unit. Second: to see whether the light is uniform color is consistent, the quality of the good bead light is very uniform, the color is consistent. The poor quality of the lamp bead will appear a lamp bead brightness, a lamp bead dark phenomenon, the luminous color is messed up and not unified, there will be obvious dark area.

LED mode for parking lighting: When the reverse gear is engaged and the headlights are on, the corner lights and reversing lights on both sides are activated to illuminate the surrounding area. After that, it will be illuminated for a short time and will be extinguished when the forward speed exceeds 7 km/h. Energy-saving mode: When the vehicle is stationary, it will automatically start and stop with the engine and automatically enter the energy-saving mode. Smart Beam LEDs have many advantages: Intelligent beam LED freeform reflector design.
