Instead of high pressure sodium lamp, Why LED corn light can do that ?


The domestic LED lighting application has been developing rapidly in recent years, many manufacturers have introduced a high power LED corn light, and energy saving products as more and more used in indoor or outdoor lighting, in the high power LED corn light really can replace traditional light source (mainly high pressure sodium lamp)?

About LED corn light energy-saving effect, in many practical cases of corn LED road lamp instead of high pressure sodium lamp, energy saving is an important factor, LED corn light than the high-pressure sodium lamp., from the practical application of the comparison of luminous efficiency, high power LED corn light, luminous efficiency (125 lm/W) is much higher than that of high pressure sodium lamp (100 lm/W), corn is a directional light, LED lamps and lanterns efficiency higher than that of high pressure sodium lamp, and high luminous efficiency, comprehensive energy efficiency much LED corn lamp in a high pressure sodium lamp.

ModelLED corn light 40Watt125Watt HPS
Luminous Flux4950lm12000lm
Efficiency(lm/w)125lm/W100lm/W
CRI8020-30
Illumination at 5meter52lx44lx
Color Temperature(CCT)3000-6500K2800-7000K
Lifespan50000Hrs28000Hrs

LED corn light color temperature problem, the high power LED corn light color temperature from 3000 k to 3000 k color temperature, can have a variety of choices, both indoor and outdoor, LED corn light can meet your requirement of color temperature.Consider the LED corn light used as road lighting, color temperature cannot too low, otherwise in the visual sense is too cold, and farsightedness eyes observation ability will decline.This aspect of some studies show that less than 3000 k of warm yellow light or white light is more suitable for road lighting, and LED corn light warm white is 3000-3500 k, so LED corn light is suitable for street lamps and practical.

The service life of the comparison of LED corn light and High pressure sodium lamp . the lifespan of LED corn light is 50000Hrs,but HPS only 28000Hrs. So using LED corn light without frequent replacement of lamps and lanterns, avoid the waste of manpower and material resources .

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 a...

The advantage of new style TEK LED panel light is obvious

Image
TEK  LED panel light , continue to use the reflective surface luminous technology, light after secondary reflection through high light transmittance mask projection, reduce glare, the light is more soft and comfortable to the human eye to watch not easy fatigue, particularly for students who have long time exposure to indoor lighting lighting, subway passengers or office staff. The application of the patented reflective material ensures the reflection efficiency of the light, and the original high light effect of the panel light is retained to the maximum extent. In order to guarantee the reliability of the use,   the design principle of TEK LED panel light  adhering to the "maintenance", improve heat dissipation performance, reduce the LED light failure of lights and lanterns, significantly prolong the service life of the lights and lanterns, saving the maintenance cost of lights and lanterns. TEK LED panel light is more intelligent TEK LED panel light c...

Safe travel: TEK LED high bay light illuminate the locomotive base

Image
In recent years, China's rail transportation has been developing rapidly, and many second and third-tier cities have made great efforts to build urban subway projects, which have brought convenience to people.Subway passenger traffic is large, the operation security is always the top priority, the metro management department attaches great importance to the security of the train, and TEK LED high bay light  illuminate the locomotive base, which facilitates the maintenance and maintenance of subway vehicles. Traditional lighting there exists large droop, short service life, the problem such as glare, can't use how long will be replaced, is not only the economy, and the human eye in this light, easy to produce fatigue, especially the night repair subway locomotive, a bit not careful see not clear parts fault, cause hidden trouble.Today, many subway lines use LED high bay lights , which make lighting more efficient and more efficient.Second, can improve work efficiency, the ligh...
