In summary, the current price of LED filament lamp beads is also relatively expensive, the table now has material costs, labor costs, efficiency, yield, development costs and other aspects. The skill is still not mature. The slender structure of the filament, the bracket is too brittle, and the crack is simple. How to produce and dissipate heat is the primary problem facing the current LED filament lamp.
First, the LED filament lamp is "true fire"
LED filament lamp is the development trend of LED in the future. LED light source can be used with patch and COB , but this kind of implementation is a helpless choice. Because the chip skills, packaging skills and heat dissipation are not enough, the chip and COB must be used to ensure heat dissipation and life. Skills are fully capable of reaching demand. In addition, the light efficiency and energy saving effect are very good, so trusting the LED filament lamp is a trend.
Second, the LED filament lamp is a "virtual fire"
There is no safety in the LED filament. The basics can't pass the safety regulations. Don't say that the European and American shopping malls are the third world shopping malls. Coupled with its ultra-low yield and painful craftsmanship, it will not be a development direction in the future. Moreover, major lighting companies such as Philips do not have any intention to acquire LED filament lamps.
As far as the LED panel filament bulb technology is concerned, the LED filament lamp with metal bracket is 360° illumination is a false problem, as for the glass bracket and the sapphire bracket. The LED filament lamp is only a transitional product, and it is a temporary product of everyone's "retro".
Using solar cell testing equipment to measure and screen, the conversion efficiency, filling factor, and appearance that meet certain standards are first level. Generally, the conversion efficiency, filling factor, and appearance of first level are better than those of level B
The level of solar panels can be divided into first level, second level, third level, and fourth level, and the first level components can be divided into first level+and first level - two levels. The second level is also the same, and the cost difference between different levels of solar panels is also very large.

Nowadays, the packaging method used in the LED panel filament lamp of the shopping mall is the formal dressing, and this dressing is simply melted at high temperature, which causes the light to decay. Although there are companies in the industry that try to use flip-chip construction to package filament lamps, the cost of this packaging method is too high, more than 30% higher than the price of LED bulbs , so many companies are reluctant to produce.
