Which drive power is suitable for LED corn light ?

LED corn light rapidly developed in recent years, in theory, the service life of LED corn light in 50000 hours, but in the process of practical application, some of LED corn light designers know insufficient or excessive pursuit of cost for the LED drive power , eventually make the LED corn light life shortens greatly, many advantages are concealed.


In the LED lamps and lanterns, there are many kinds of connection methods.Which LED aluminum plate, LED drive power supply circuit serial-parallel has a lot of, need to arrange multiple LEDs together, reliable LED connection mode to improve the efficiency of LED corn light and life play a large role.


LED drive power supply is the key to LED corn light, it is like our human heart, to produce high quality LED lamps and lanterns ,must learn to "let go", that is no longer choose constant pressure way to drive the LED lamps and lanterns.


Many staff design LED lamps and lanterns, resistance, capacitance step-down, then add a diode voltage stability, supply power to the LED. Such way has greatly flaws, not only low efficiency, and consume a large amount of electric energy in the step-down resistance, may even more than the LED by consumption of electricity.


Constant current source driving is the best way of LED corn lamp drivers, driven by constant current source, not in the output circuit in series current limiting resistor, LED on the flow of current is not affected by the outside power supply voltage, temperature changes, and the influence of LED parameter discreteness, thus to keep the current constant, give full play to all kinds of the good qualities of LED corn light.


Using constant current driver can not only make LED lamps and lanterns of normal play its role, and won't be dangerous.At the same time, also can let the life of the LED corn light intact.

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
