Dose LED street light appeared stroboscopic have relations with the isolated power supply?

TEK lighting LED street lamp: first of all, we want to make sure, as long as lamps and lanterns use alternating current power supply in theory, will have possibility of stroboscopic. Although LED street lights is dc power supply output, but it is always 220V AC input, it is difficult to completely avoid ac ripple through the LED light source.

Thus it is not hard to see, LED street light stroboscopic factors mainly depends on the LED driver power supply for the sensitive degree of voltage fluctuation. If high sensitive degree, there is a small voltage current fluctuation will cause stroboscopic.Then aiming at the common two types of power supply on the market - isolation and non-isolated to distinguish.

The difference between isolation and non-isolated
Power source is 220V alternating current into direct current drive, isolation power by electromagnetic induction between the coils, converts high-voltage alternating current (AC) into low voltage direct current (dc), electrical components are between each processing, safety performance is high. Non-isolated power supply is through electronic components to convert high-voltage alternating current (ac) as the low voltage direct current (dc), the connection between electrical component processing, safety performance is low and short service life.

TEK lighting LED street light using isolation power supply and Philip chip can efficient ensure the brightness and the safety of the pedestrians. And provide 5 years warranty , widely used in arterial roads lighting, highway street lighting, city street, bridges, sidewalks road lighting, school lighting, factory road lighting, park lighting, parking lot lighting and other outdoor lighting places need.

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

Image
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...
