Ascending Photoelectricity: COB technology, the only leader

[Text|High-tech LED reporter Luo Shenghua] "The demanding requirements of the market, while giving pressure to COB packaging companies, also promote the industry forward." Ye Bing, manager of Ningbo Shengpu Optoelectronics Marketing Department.

Founded in 1990, Shengpu Optoelectronics Co., Ltd. is a modern high-tech management enterprise integrating high-end LED device packaging and LED lighting. At present, it has more than 40 independent patent technologies, and new products and new patents are constantly available in the fields of COB light source and light engine.

“At present, COB light source sales have reached 50% of the total package weight” Ye Bing stressed.

Due to the technical advantages of COB packaging technology for commercial lighting and the significant reduction of the overall cost of lighting applications, the application of LED products is of great significance.

"COB light source surface light source personalized design, high reliability, high light efficiency and high index is very suitable for commercial lighting and industrial lighting needs, the bulb, spotlight market is also gradually introduced, COB light source needs a development process, in some commercial lighting The field, becoming a mainstream light source, is a trend."


In 2008, the company began to develop COB light source, which was the earliest in China. The first generation technology developed at that time mainly focused on improving luminous efficiency.

In 2015, Ascent Optoelectronics upgraded its COB products. "Smart COB with intelligent control is the focus of our promotion this year." Ye Bing said.

It is understood that this intelligent light source needs to cooperate with the intelligent drive to simulate various kinds of sunlight from morning to night in the lighting effect.

At the same time, with the rapid development of commercial lighting, the market demand for COB light source is more and more demanding. From the 270 degree wide angle illumination to the birth of the ultra-wide angle 330 degree bulb, the COB packaging industry is gradually maturing. However, COB light sources also have problems such as limited angle, loss of light, and uneven light. How to solve these problems has become a problem that every COB packaging company has to think about.

Ye Bing introduced that the personalized COB structure independently developed by Shengpu not only directly replaces the LED filament series in the advantage of 360° wide-angle illumination, but also its light decay, longevity and reliability, which also wins the filament series, truly satisfying customers 360°. The design requirements for wide-angle bulbs.

LCD Module

According to the different backlight sources, LCDs can be divided into two types: CCFL displays and LED displays.
Misunderstanding:
Many users believe that liquid crystal displays can be divided into LEDs and LCDs. To some extent, this understanding is misguided by advertisements.

The LED display on the market is not a true LED display. To be precise, it is an LED-backlit Liquid Crystal Display. The liquid crystal panel is still a traditional LCD display. In a sense, this is somewhat fraudulent. nature! South Korea`s Samsung was once convicted by the British Advertising Association as violating the country`s advertising laws because its [LEDTV" LCD TVs were suspected of misleading consumers. For liquid crystal displays, the most important key is its LCD panel and backlight type, while the LCD panels of displays on the market generally use TFT panels, which are the same. The difference between LEDs and LCDs is only their backlight types: LED The backlight and CCFL backlight (that is, fluorescent lamps) are diodes and cold cathode lamps, respectively.

LCD is the acronym for Liquid Crystal Display, which means "liquid crystal display", that is, liquid crystal display. The LED display refers to a type of liquid crystal display (LCD), that is, a liquid crystal display (LCD) with LED (light emitting diode) as the backlight source. It can be seen that LCD includes LEDs. Corresponding to the LED display is actually a CCFL display.

(1) CCFL
Refers to a liquid crystal display (LCD) with CCFL (cold cathode fluorescent lamp) as the backlight source.
The advantage of CCFL display is good color performance, but the disadvantage is higher power consumption.

(2) LED
Refers to a liquid crystal display (LCD) that uses LEDs (light emitting diodes) as a backlight source, and generally refers to WLEDs (white light LEDs).
The advantages of LED displays are small size and low power consumption. Therefore, using LEDs as a backlight source can achieve high brightness while taking into account lightness and thinness. The main disadvantage is that the color performance is worse than that of CCFL monitors, so most professional graphics LCDs still use traditional CCFL as the backlight source.
