What ways can see LED street lights to replace the high pressure sodium lamp?

Under the condition of current technology,luminous efficiency of LED street lamp is more than high pressure sodium lamp, it is an indisputable fact that TEK LED street lamp can reach 160 LM/W. And HPS spectrum is concentrated in the yellow area, its color temperature is low, only 2000-2500 k, and relatively high color temperature such as LED, LED street light natural white temperature of 4000-5000 k, cold white is 5000-6500 k. At the same time compared with HPS, LED street lamp with high color rendering index, close to natural light in the actual lighting, can bring a person the sense of comfort.

Followed by "irradiation uniformity", although the LED street lamp lighting is relatively concentrated, but can be by the light path of the second design, can make the light source of lamps and lanterns presents the ideal state, realize the reasonable light distribution curve adjustment, control the distribution of light, so as to realize the uniformity of illumination.

Then the problem of "droop", in the process of practical application, due to long-term high temperature working environment, the service life of LED street lights will be affected, so only by strengthening the cooling way to prolong the service life of LED street lights. At present, TEK lighting has obtained the good effect for heat dissipation of LED street lights, can cut the junction temperature of LED street lights to 63.9 ℃, at that temperature, if the lamps and lanterns to work 12 hours a day, the light failure is less than 3%.

Finally is "life", high pressure sodium lamp life only 20000 hours, and LED street lamp can normal use 50000 hours.Regardless of HPS light failure, single from the life of LED street lamp is 2 times of high pressure sodium lamp.

Above all, compared with using HPS road lighting, the LED street light to energy conservation and environmental protection.There is no doubt that with the progress of science and technology, energy-efficient light source will be constantly emerging, as a road lighting designers should be innovative design, at any time to master the use of new technology and new equipment, lighting has always put the energy conservation and environmental protection to work first.
