1.High luminous intensity, irradiation distance Current LED luminous efficiency has been achieved 120Lm / W, has far exceeded the high-pressure sodium lamps (80 Lm / W), fluorescent light (60 Lm / W) and other light sources, and LED light-emitting angle of 160 º 180 º, all the light energy can all be projected to the illuminated surface, the other light sources are emitting angle of 360 º, it is usually only half of the light energy projected onto the illuminated surface, so in the case of the same light effect, LED lights luminous intensity (angle of the luminous flux unit) than Other lamps twice as high, so luminous intensity LED lights (that usually people perceive the light intensity) is much higher than other light sources. Because LED light emitting angle is small, so the light project very far, especially suitable for Spotlight. 2.Significant energy saving, particularly long life. By the authoritative department, LED light intensity with the power is about 16 times than incandescent light and 6 times than energy-saving and 2or 3 times than high-pressure sodium lamp and therefore to ensure the same brightness (luminous intensity) under the conditions LED light than other light sources can save 50% to 90% energy and saving effect is very obvious. LED lamp life of up to 100 thousand hours in theory, present the actual life expectancy can reach up to 60,000 hours, the maximum life span of other light sources are less in 10,000 hours, so the life of LED lamps for light longer than other light sources 6 and 10 times, so not only can save the cost of replacement lamps, but also significantly reduce maintenance costs. Should be specified, the series of LED lamps for light use by the circle transformer and switch-mode step-down constant current driver control mode, not only greatly improve the reliability of drive power, and control the efficient, power supply may also be to ensure continuous operation 5 years. 3.Rich colors, color display of very high LED lights can directly produce red, blue, yellow, green, purple and other colors of light, and also by several synthetic white light, therefore particularly suitable for LED lighting project to beautful the city. LED light color is very high, typically 80 or more, so the light can really show the color of the illuminated scene. High-pressure sodium lamps commonly used in color index is only 30, many objects in color in the high-pressure sodium lamp irradiation, will be seriously distorted. 4.Tight seal, waterproof superior performance All components of the series of lamps together through the sealing gasket and sealing effect is very good, not afraid of wind and rain, and even long-term placement in underwater work. 5.Elegant and generous, very good cooling effect The series of lamps produced shell casting process, the structure is very fine, is particularly stylish in appearance. Lead alloy shell not only guarantees the robustness of the lamp, but also played a very good cooling effect. Continuous operation at room temperature, the shell of the operating temperature is usually not higher than 45 °C, can reduce the LED light decline to extend the LED life.
