SMD or COB, who is the mainstream of downlights?
High power started in the field of downlights in 2011. The patch should be applied to downlights in the second half of 2012. In the second half of 2013, COB began to fire, and it changed too fast every year. Last year, the LED downlights of the patch light source were a little more. This year, the COB will be much more. Slowly, the LED downlights will go in the direction of high-quality COB. The COB downlights will be on fire for a year or two. Patch applications have 4--5 years, but the patch is flat downlight, see a plane body, now it requires anti-glare, instead of seeing a plane body, so the future is certainly COB mainstream. The COB light source was applied to LED downlights in 2012 , and now the downlights are mainly COB . “It is deep-faced and has anti-glare, brightness, illumination, and strength.â€
In 2008, I started to develop LED downlights. I used straw hats and beads, and I have experienced 3528, 3014, and 5730 lamp beads applications. Now I have reached the COB light source. Now LED downlights have basically been finalized, and the COB has reached the peak of the LED downlight source. , COB light source lamp 2012 began to be used in 2013, rapid development, large-scale application in 2014. Nowadays , the quality of COB is becoming more stable, the color consistency is good, and the production process is mature. In 2010 , perhaps everyone will say that high-power products are the mainstream. In 2013 , everyone will say that the patch is the mainstream, then today, in 2014 , when you go to the market, whether it is the dealer or Consumers, they will tell you in unison that COB light source is the real mainstream. The COB light source solves the problem of chromatic aberration and heat dissipation well, and has won the favor of the market and consumers. Jiamei Zhiguang is mainly based on COB light source.
Many people in the industry are very optimistic about the application of COB light source in the field of LED downlights, and believe that COB is the mainstream of future development. However, there are also different views. The current downlights only have patches and COB light sources. At present , the amount of COB downlights is still small, mainly for patches. The patches basically lead the entire LED downlight market. The previous high power was mainly used to make ceiling lights, and COB was mainly used for spotlights. The patch is scattered, the heat dissipation is good, the life is long, the light color is better, the light is more uniform, and it is suitable for public lighting. Good light efficiency and long life are the advantages of patch downlights, so the patch is most suitable for downlights. The downlight is definitely the patch of the world, the patch is even and cheap, and the downlight is the space lighting effect. It is not the ceiling projection. It is wide angle, uniform light, low cost and thin pursuit. The film is very suitable for downlights, COB is mainly used on spotlights, and the downlight is just a concept.
Economical products, products that are in circulation must be patched. The consumer's control and light efficiency requirements are not very high, and they are very sensitive to cost. The large wattage is definitely a COB light source. It belongs to two ends, one is high-end and the other is low-end. At present, high power is rarely used in downlights, because the biggest drawback of high-power downlights is that it is easy to see a single lamp bead, and the light is uneven.
Technology innovation or increase functionality, who is the future development trend?
In June of this year, the ED zoom downlight was officially unveiled, which is also the first LED zoom downlight in the world. The beam angle of LED lamps currently on the market is fixed and the application range is limited. After the realization of the LED light speed angle is adjustable, such LED lamps will be more widely used in a variety of indoor projects, such as museum displays, hotel rooms and so on.
For LED downlights, zoom downlights are a major innovation.
In terms of technology, the development trend of LED downlights is COB and flip-chip. Other aspects are dimming and adding some functions. LED has a lot of functions, the key is how to achieve it later. In addition to intelligence, the application range of LED downlights will also be expanded, especially in the showrooms for automobiles, mobile phones and clothing. In the next 5 years, Auman Technology's LED downlight series products will develop towards the following trends: indoor and outdoor, which can be used for decorative functions and advertising functions. The performance can be added such as anti-theft, fire prevention and air purification. In terms of product features, the cover is made of acrylic material, uniform light color, anti-glare, high light transmittance; built-in power supply for easy installation; and wireless remote control dimming, light control switch, voice control switch, human body sensor switch and other functions.
We know that there is a process from incandescent lamps to energy-saving lamps to LEDs. Perhaps one day, there will be new technologies to replace LEDs. At this stage, we all say bad. However, today, when most companies are still worried about using radiators to solve the product's light decay, the COB downlight products below 15W no longer need radiators.
