The four requirements of solid-state lighting for high power LED street lamp encapsulation

Compared with traditional lighting, LED street lamp does not need to use filter to produce light, not only high efficiency, light color purity, and can realize dynamic or gradient color changes. In the change of color temperature while maintaining high color rendering index, can meet the needs of different applications. But the packaging is also put forward new requirements.

modularization
Through multiple leds (or module) are connected can achieve good lumen output superposition, meet the requirements of high brightness illumination.Through modularization technology to use multiple point lights or LED module shall be carried out in accordance with the random shape combination, meet the requirements of different areas of the lighting.
systems to maximize efficiency
To improve the efficiency of LED street light, in addition to need the right LED power supply, also must adopt efficient heat dissipation structure and craft, and optimization optical design, to improve the efficiency of the whole system.

the low cost
When LED street light go to the market, must have the competitive advantage on cost (mainly refers to the initial installation costs), and encapsulation in the LED street lamp production costs account for a large part, therefore, adopt new encapsulation structure and technology, improve the light efficiency/cost ratio, is the key to realize commercial of LED street lights.
easy to replace and maintain
Due to the LED light source has long life, low maintenance cost, therefore to the LED street lamp packaging reliability is put forward higher requirements.Requirement of LED street lamp design is easy to be improved to adapt to the future more efficient LED chip packaging requirements, and the LED chip interchangeability is better , so that the LED street light manufacturers choose what chips.
LED street lamp light source can be composed of multiple distributed point source, because the chip size is small, so that the encapsulation of lamps and lanterns is light weight, compactness, and can meet the needs of various shapes and different level of integration.
In addition, the first target is power of LED lighting control.Due to the mains supply is commonly high voltage alternating current (220VAC), LED need constant current or current limiting power, so you must use conversion circuit or embedded control circuit, in order to realize the advanced calibration and closed-loop feedback control system.

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...
