LED street lamps: not to say that energy conservation is good, but also to see other important technical indicators

Judge a LED street price performance, not to say that energy conservation is good, but also to see other important technical indicators, but high-quality LED street lamps, but also to see other important technical indicators, as follows:

1, color temperature: LED, lamps, color temperature is mainly between 2700K - 7000K. In general, the lower the color temperature technology, the greater the difficulty, such as 3000K color temperature, can be used in a variety of occasions.

2 glare value: glare refers to the visual conditions due to inappropriate luminance distribution or extreme brightness contrast in space or time, resulting in visual discomfort and visual reduction of objects. It is through the Purdue diffuse, eccentric reducing glare light value.

3. Luminous efficiency: the ratio of the total luminous flux emitted by the light source to the electric power (Watts) consumed by the light source is called the luminous efficiency of the light source. The higher the efficiency of the theory of light, the world has now appeared in the lighting efficiency of 110lm/w lamps, is currently the best standard of universal.

4, lamps and electrical performance: LED street lamp in nominal rated power voltage and rated frequency work, the actual consumption of power and rated power difference should not be greater than 10%, power factor should not be less than 0.95.

5, protection level: LED street lamp protection class a product should not be lower than IP67; B class products should not be lower than IP66; C class products should not IP65. At present, IP67 is the highest standard of street lamps.

6, average life: LED street lamp rated average life should not be less than 50000h.

7, maximum temperature: LED street lamp rated maximum temperature Tc value should not be greater than 58 degrees centigrade.

8 maximum heat sink temperature: the maximum heat sink temperature of each LED tube in the luminaire shall not be greater than 65 degrees centigrade.
