LED and OLED difference

LED and OLED as a new type of semiconductor lighting technology, known as the fourth generation of lighting or green light source, compared to traditional lighting products, it has energy saving, environmental protection, long life, small size, can be widely used in a variety of instructions , Display, decoration, backlight, general lighting and city night and other fields. Therefore, in recent years, some economically developed countries in the world are actively developing LED and OLED semiconductor lighting. However, LED and OLED due to the working principle and the production process is different, there are their own characteristics. LED light bars LED full name is a light-emitting diode, generally use III-IV inorganic semiconductor materials and chemical vapor deposition (CVD) process manufacturing. As with the traditional semiconductor industry, the cost of the process is higher, it is difficult to achieve large size. Therefore, LED can only be used in the form of point light source. In the field of indoor general lighting, in order to achieve a certain degree of space lighting brightness, LED needs a high luminous brightness, so in order to prevent glare, resulting in soft light, LED often have to install the lampshade use. But this way, LED lighting luminous efficiency will also decline. If you want to use LED to produce surface light source, such as LCD backlight, you need to combine multiple LEDs and with a light guide plate and other complex optical system. In addition, the luminous efficiency of the LED will drop sharply as the temperature increases. Autolumination Instrument Panel Light Bulbs Lamps As the LED volume is very small, the heat generated when the operation is difficult to spread out in time, it must be equipped with LED cooling device cooling device. Based on the above reasons, LED light source technology advantages such as luminous efficiency, lightness and cost advantages, in the production of lamps will be greatly discounted. At present, white LED is generally used to cover the use of blue LED phosphor way (as shown). Phosphor is excited by the blue light emitted by the LED will produce yellow light, and then together with the blue light blue LED mixed with white light. Although this approach is low cost, but there are many shortcomings. H13 Led Conversion Kit
