Compared LED cor light and high pressure sodium lamp, find the advantages of LED corn light?

We always said  LED corn light is a good lighting product, how good it ? let us though compared LED corn light and high pressure sodium lamp (HPS)  to learn about it.

Light color of HPS is yellow , color temperature and color rendering index is low. Color rendering index of sunlight  for 100, HPS color rendering index is only 20 (yellow) .  LED corn light color temperature can be flexible to choose between 3000-6500 k, color rendering index can reach more than 80, lamps and lanterns emitting light colors is more close to natural light.


HPS structure determines the utilization rate of the light source of lamps and lanterns is low, only about 40%.Most of bulb light Angle is 360 ° must pass the reflector reflection to exposure to the designated area. light utilization efficiency of LED corn light is high, about 90% of LED diode light Angle can keep consistent with the light Angle of lamps and lanterns, so most of the lamps and lanterns is direct exposure to the designated area, only a small part is through reflection, thus to improve the utilization of light source.


HPS startup time long, start again requires a certain time interval. HPS with the power of about 5 to 10 minutes of time to reach normal brightness, start again time interval is generally than 5 minutes. LED corn light there is no delay start, you can always turn on the work at any time, can be very easy to implement intelligent energy-saving control.


the temperature difference  between light and light went out  is very big, if without the breathing system, light body reflector are easy to be corrosion of harmful gas to produce a larger light loss. LED corn light does not need to add the respiratory system, it is composed of solid cold light source.

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 can form a

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 as to realize the uniformity of illumination.

Rule of thumb: what are the installation instructions of DALI LED high bay light?

Image
DALI LED high bay light , also known as LED warehouse light, mainly used in factory workshop, warehouse, exhibition hall, etc., have gradually entered homes, because it is using the latest LED lighting energy saving technology, high reflectivity, high power, high utilization rate of light source. But good lamps and lanterns need specification installation, to highlight its advantages, below for everyone to explain the DALI LED high bay light installation: 1，Define DALI LED high bay light installation height according to the lighting environment, because the environment will change the reflection efficiency of lamps and lanterns. Usually the height of DALI LED high bay light  should be above 5 meters, thread is not close to the lamp shell. If installation height is less than 3 meters, protective measures must be taken to prevent a vehicle to touch. 2，TEK DALI LED high bay light protection class is IP65, choose waterproof transformer, chip packaging place with high temperature resi
