As far as the development of the green energy industry is concerned, LED lighting can be said to be the best application for promotion. However, overall, the popularity of LED lighting is still limited to the application of street lighting and commercial environments, and the progress of household lighting is relatively backward. At present, the LED lamps used in household LED lighting are mostly LED downlights and LED bulbs, and indirect lighting is mostly light strips. If subdivided, there are MR16 size downlights, E27 lamp head LED bulbs, E27 lamp head LED decorative lights, E14 lamp headboard headlights, etc. Currently, many manufacturers have introduced related products, however, LEDs If lighting is to enter the home environment in a big way; and then completely replace traditional lighting equipment, there must still be breakthroughs in price and performance, especially high-power LED lighting.

In terms of price, the retail price of 1.2-meter-long LED tube is nearly 200 yuan, and the price of traditional fluorescent tube of the same length is less than 10 yuan. Such a price gap is definitely the biggest obstacle for LED lighting to enter the home environment. However, the industry pointed out that with the maturity of technology, in three to five years, the cost of LED lighting will continue to decrease, reaching the price acceptable to ordinary consumers, that is, between 40 and 60 yuan.
In addition to the price, the luminous efficiency of high-power LED lamps is also a big problem. Taking a 5W, 10W or 13W LED bulb as an example, the LED illuminating efficiency of the LED is about 50 lumens to 80 lumens per watt. However, the actual light extraction efficiency may be discounted due to factors such as the structure and light type of the luminaire. Furthermore, according to a survey conducted by the Taiwan Consumers Foundation, the price of a 20-watt LED bulb is 12 times that of an energy-saving bulb, but under the same power, the brightness of an LED bulb is only 80% of that of an energy-saving bulb. In addition, the shortcomings of the LED heat sink, such as excessive volume and poor color rendering, need to be improved.
Up to now, compared with energy-saving lamps, it is quite common in home buildings. For example, replaceable bulbs (E27), ceiling lamps, recessed lights, ceiling lamps, etc. are all areas where energy-saving bulbs excel. The LED lighting products on the market are mainly based on MR16 series lamps, freezer lighting, light bars, track lights, cabinet lights, landscape lights and arch lights, night lights and other applications. According to the two factors of comprehensive performance and price, the industry generally believes that if LED lamps want to replace the general energy-saving light bulbs, firstly, the luminous flux of LED bulbs must reach 1000lm to cope with most indoor lighting needs. Furthermore, the cost of LEDs must be reduced to every thousand. Lumens 1 US dollar (USD $ 1 / Klm), in order to speed up the popularity.
