How to replace a GU10 bulb:
1. Squeeze the clip (or use sucker provided) to release the bulb from the fitting
2. Turn bulb counter clockwise to ‘unhook’ from the power supply
3. Twist new bulb clockwise into position
4. Replace clip

Most people are already familiar with LED applications in everyday life, such as LED bulbs, LED street lights, car lights, and LED plant growth lights, outdoor LED display billboards. Now the LED industry is further developing the Mini LED and Micro LED technology, so that the LED application will be presented to the next level.
Most people are already familiar with LED applications in everyday life, such as LED bulbs, LED street lights, car lights, and LED plant growth lights, outdoor LED display billboards. Now the LED industry is further developing the Mini LED and Micro LED technology, so that the LED application will be presented to the next level.
Mini LEDs and Micro LEDs are smaller in size than existing LED products. According to the industry, the grain size of the Mini LED is about 100 microns or more, while the grain size of the Micro LED is less than 100 microns, even within 50 microns. With the grain size comparison of the general LED products on the market, the LED die is about It is 20 to 30 times larger than the Micro LED.
At present, the industry has begun to ship Mini LED related products, and Micro LED is mostly in the product development stage, and it is estimated that it will take three to four years to mature. Some manufacturers believe that Mini LED is a transitional technology before the mature market of Micro LED, but there are also people in the industry to evaluate that the future Mini LED and Micro LED technology have the opportunity to coexist and apply in different fields. Industry insiders estimate that by 2022, the market value of Micro LED and Mini LED will reach 1.38 billion US dollars.

Compared with the current general LED backlight, when using the Mini LED backlight, more detailed local dimming can be performed, for example, the place where the black color is displayed is blacker, the contrast is high, and the color expression is better.
According to industry insiders, Mini LED is used as the LCD backlight architecture. It is similar to the LED backlight architecture of current LCD monitors. It has not changed much in design. However, for consumer electronics such as mobile phones or TVs, Mini LEDs are bound to face directly. Competition from OLEDs.
According to industry insiders, the Mini LED shrinks the LED chip size to 100 to 300 microns, and the backlight module is covered with LEDs. For example, the 5.5-inch FHD screen uses up to 2,000 to 10,000 LEDs. When the number of LEDs is small, a long optical distance is required, so that the thickness of the whole machine is increased. When the number of LEDs is large, although the optical distance required for the backlight can be shortened and the uniformity is better, heat dissipation problems are derived and The cost has increased dramatically, and how to achieve a balance is the bottleneck still to be overcome.
The industry also believes that the OLED smart phone panel offer is still relatively weak in the long run, so if the Mini LED can not reduce the cost, it will be difficult to compete with the OLED for the high-end smart phone market. But in a niche market with higher profits, cost is not a priority, so the chances of importing Mini LEDs are much greater.
Due to the high cost in the early stage of development, most of the current Mini LEDs are used in higher-order, target-oriented customers who are less sensitive to price. For example, the LED manufacturer's Mini LED backlight products have been applied to high-end esports notebooks. And high-end graphics display, its 32-inch Mini LED divides the backlight into 384 control areas for high dynamic contrast.

As for Micro LED, one of the technical bottlenecks that the industry is striving to improve is the huge amount of transfer, which is how to make tiny Micro LED dies on the substrate in the most efficient way. With the various transfer programs coming out, it is expected that there will be more cost-competitive technology solutions in the future, and there will be opportunities to accelerate the development of the Micro LED.
