The LED flood light and LED Spotlights are often confused by us, there is generally no lens for the LED flood light, the light angle is relatively large, which is typically 120 °, the illuminated area of the LED floodlights is relatively large, but the irradiation distance is not far. There is generally a lens for the LED Spotlights, the angle the light shines out can be determined by the size of the lens, the irradiation area of the LED spot light is generally not large, but the irradiation distance is far. The component of the LED flood lights 1 glass + Reflector + LED integrated light source (cob) + led Power + die-cast aluminum housing = LED flood light 1, tempered glass. Process: There are two types, one is physical tempering,the other chemical tempering. Physical tempering is that the ordinary glass or float glass is produced by quenching pyrometallurgical process or cooling in the specified conditions and circumstance. Chemical tempering is that the composition of surface of the ordinary glass or float glass is changed by ion exchange method to form a compressive stress laminated layer on the glass surface. Discern good and bad: Check the flatness, no bubbles, inclusions, scratches, lanes and fog spots and other defects, such defects of the glass, the deformation will occur in use, reducing the transparency of glass, mechanical strength and thermal stability of the glass. 2, the Pan-mask Identification method: no distortion, no spinning lines, pinhole, bright surface, the surface without obvious sand holes, better gloss plating, plating thickness should be uniform. 3, LED integrated light source Discern good and bad: through a microscope to see whether the chip is from the desired manufacturers (Corey, Prius, wafer, etc large-size chips is currently hotter on the market.), the chip size is whether the chip required. There are Square chip, wafer, raw footage, confirm the chip is good and bad. according to the specifications the manufacturers producing LED Flood light tell you, glue, bracket, LED phosphor composition also determines the quality of the LED flood light, there is not individually listed. 4, LED power Discern good and bad: First we need to refer to the data. Such as: buy a 50W LED floodlight, and what the vendors give you the product power is 56W or 46W, which is NG. Specific issues is based on the standards to measure on time of purchase. LED power efficiency and power factor conversion rate determine this supply is good or bad, so the better,the higher the value. the insulation protection is very important for the Non-isolated power,I heard that a lot of customers have said there was a feeling of the electric shock on the surface of some low-end brand LED Flood light, even more outrageous is that the leakage is more than 100 volts. 5, die-cast aluminum housing Discern good and bad: the Shell decide that whether the heat dissipation of the product is good in future or the light decay is in the normal range. Now the manufacturer basically manufacturing the LED flood light purchase kit and then assemble, having never considered the product heat. Some manufacturers use the scrap in order to reduce the cost of the aluminum. Because there is no way to simply distinguish the good and bad of the aluminum for the customer. The best way that is to identify the stabilizing is test. Lead lighting has been continuing to strengthen the use of certified raw materials such as LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the LED Flood light and LED tunnel light and other outdoor lighting,adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ,the soft and bright light of the LED tunnel light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets. visit www.ledclan.com to Learn more vivid and specific characteristics of the LED tube light or click www.lead-lighting.com for more detailed and professional features and uses of the LED lighting.
