Development of LED downlight

From traditional downlights to LED down lights, the whttp://www.crown-led.com sources are constantly being updated, from the previous fluorescent lamps to straw hat lamp beads, LED high-power lamp beads, to today's chip lamp beads (SMD) and LED integrated light source (COB) , The development of downlight round LED can be described as one step each year. Nowadays, with the continuous maturity of indoor down lights technology, its market scale is showing geometric development. Facing the huge market space, major qualtity led down light manufacturers have also launched fierce competition.
　　
LED downlight usher in the fourth generation of light source
　　
Today, recessed led down lighting have gone through the two stages of the traditional downlight era and the LED downlight era.
　　
The era of traditional downlights has gone through three more generations. Among them, the first-generation traditional downlight adopts a vertical embedded form, and the light source is directly installed in the lamp cup in a vertical manner. In this way, the first-generation downlight has some shortcomings: it occupies the ceiling space, reduces the height of the house, and the light source is prone to deviation and leakage, thereby reducing the efficiency of the light led source.
　　
The second-generation traditional downlight adopts a horizontal embedded form. Although this solves the problem of the height of the downlight, the horizontal embedded form has a wider width. And the second-generation downlight adopts the horizontal light source form. On the one hand, it reduces the utilization area of the light source and reduces the utilization rate of the light source, which is a waste of energy. It also breaks the light distribution design.
　　
The third generation of traditional downlights realized the perfect combination of light source and lamps, solved the shortcomings of the first and second generation of downlights, and brought together the advantages of traditional downlights in light efficiency and structure.
　　
Then, the downlight ushered in the LED era.
If you calculate the replacement according to the led lighting source, the LED down lighting fixtures can be said to be the fourth generation. The first generation uses straw hat beads, the second generation is high-power lamp beads, and the third generation is SMD lamp beads (SMD) and the third generation. Four generations of LED integrated light sources (COB); if you count according to the style, it is countless.
