Identify the advantages and disadvantages of LED high bay light

With development and constant improvement of LED technology, LED in lighting field permeability has been maintained a high growth momentum.And lighting time is long, large energy consumption of industrial lighting, gradually become the latest must-haves in the LED lighting manufacturers, all LED lighting manufacturers are basically in industrial lighting field, and as the main industrial lighting products，LED high bay light became every manufacturer must to do.But the problem is that in the  allocation of resources is unequal,  technical strength is unbalanced.  It is easy to appear the quality problem .


Analyze LED high bay light from the structure , can be divided into three main components: LED light source, LED driver, LED heat dissipation.How to distinguish the quality of the LED high bay light,  layman can from the following several aspects to distinguish good or bad :

1, compare the luminous efficiency of LED high bay light, measuring the flux , luminous efficiency  (single flux value) more than 90 lm/W belong to high luminous efficiency product , luminous efficiency is lower than 80 lm/W belong to low light efficiency product .

2, compare the PF value of LED high bay light,  PF value is between 0.90 ~ 0.96 best, PF value higher than 0.96 is too high, PF value below 0.9 belong to the poor quality.

3, compare the conversion efficiency of l LED high bay light, measuring the actual power and light source power of the lamps and lanterns , conversion efficiency is more than 80% belong to the qualified products, less than 80% belong to the inferior products.

4, IP protection index, if use big environmental dust, humidity,  requires the disposal of the IP protection, otherwise the service life of the LED high bay light will be significantly reduced.

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
