It is well known that the LED is the fourth generation of light source of the revolution, the first generation of lighting is all kinds of fire, the second generation of lighting is all sorts of incandescent lamp, like a normal light bulb, halogen lights, the third generation of lighting is all kinds of gas or arc discharge lamp, such as fluorescent lamp, fluorescent tubes, energy-saving lamps, gas discharge lamp, in the late ninety s, 20th century based on semiconductor light-emitting diode (LED) of solid-state lighting, instead of incandescent lamp and fluorescent lamp into the field of general lighting of 100 watt equivalent led.
Notable is, the former three generations of the light source of the light emitting mechanism about surface, especially the second and third generation of lighting, lamps and lanterns of the core technology was “reflector”, “reflector” quality determine the efficiency of lamps and lanterns, such as street lighting, outdoor lighting reflector light distribution efficiency of different quality different, a direct impact on the road of the intensity of illumination and uniformity requirements and 3014 led bulb.
Today’s LED single star lighting system for optical light distribution, 360 degree led,structure, process, production standardization has brought certain difficulty, makes some companies go detour, some top packaging companies in the industry, in view of the street lamp light distribution requirements, carefully designed production suitable for road lighting requirements of one-time peanuts lens encapsulation light source, optical light distribution, structural design, and production process to reduce a lot of trouble, it’s a pity that there are some enterprises by the so-called “high photosynthetic efficiency” misleading to abandon the use of this product. The defect of blindly following choose whole lens, the lens is gradually exposed. Attended by the illumination of surface light-emitting way, industry began to experiment with street lamp production fluctuation kongfu, avoid to the promotion of evenness and glare play an unexpected effect.
