LED filament lamp deposit is still in the primary stage of the development of the four major difficulties

Although the global no white and technological progress to a certain extent, boost the development of LED filament lamp, LED lamp filament prospects is also very long, but many industry insiders said, at this stage, LED filament lights still is still in the development stage. LED filament lamp seems shengfengjishi, but many criticized the existing look impressive but lack real worth, and also let it not usher in their golden period "development". So, LED filament lamp at the present stage of the development of the problems facing?

Low yield

Difficulty: assumes it

Compared with the traditional incandescent lamp, LED filament lamp has higher requirements on the packaging. It is reported that the current LED filament lamp of filament voltage, filament current design design, LED chip, LED chip area and the power angle, pin design, glass bulb row sealing technology has very strict requirements, the process that LED filament lamp was complex, there are certain requirements for the manufacturers the strength of the fund, facilities and technology etc..

In the production process, due to the different processes, the material requirements, coupled with production, a lot of equipment needs to be modified according to the performance characteristics of LED filament lamp, which makes LED filament lamp related materials manufacturers miserable. Ball bubble material defects also let the LED filament lamp in the course of its transport is easy to damage and so on, the process is complex, low yield so that LED filament lamp can not get the manufacturers and consumers.

Difficult process, poor heat dissipation, easy to damage

Although in recent years the LED filament lamp is popular in the domestic market, but for now, LED filament lamp which exists in the production problems still can not be ignored: the process is difficult, the need to integrate several different process and low yield; more than LED filament lamp 8W is easy to appear the problem of heat dissipation; easily broken, easy to damage during production and use.

Structure, performance and price to be improved

Shenzhen Hongxin lighting general manager Liu Qiyu

Because the LED filament lamp to enter the market relatively late period, the market bubble and bubble, sharp pull bulb with "SMD" filament lamp with First impressions are strongest, early to enter the market in the structure, performance and price are expected to far away from the consumer, the consumer has some misunderstanding of LED filament lamp. With the breakthrough of the key technology, the maturity of the packaging technology, the improvement of the sealing technology, the light efficiency, the apparent temperature, the life and the cost of the LED filament lamp will be improved to some extent.

To improve the light efficiency and reduces light attenuation

FSL LED division director Chen Wenji

For now, I think LED filament lamp in the technology has been relatively mature, but the proportion of the filament lamp cost is too high, the future also need to reduce the cost of LED filament efforts. In addition, the enterprise also to improve the LED filament lamp quality stability, improve the lighting effect and improved filament reduce the light on.

Improvement of raw material and production process

Liang Dicheng, general manager of Zhongshan filament lamp lighting

At present, the LED filament lamp need to improve the place too much, she is like a newborn baby is not mature in all aspects, high cost, complex production process, low production capacity. Therefore, the following should be improved in raw materials and LED lamp and manufacturing process, make LED filament lamp capacity increase, reduce loss, improve shipping efficiency.

Small power, poor heat dissipation is hindered

The general manager of Zhongshan and Wang Liang Lighting Co. Ltd.

Due to the influence of the production process, there are many problems in the current LED filament lamp, such as the high cost and the defects of the foam material. In addition, the heat problem more LED filament lamp has become LED filament lamp into the common people of the obstacles.

LED filament lamp market advantage is not obvious

Ayura Terua, director of marketing, Shanghai, Changqing

Xuzhou Yapu'er agents introduced from the terminal market, LED filament lamp bulb, tip relative to the product bubble LED light source products is not a qualitative change, but the price is relatively high, it is difficult to go, not to mention to replace the LED bulb, energy-saving lamps and other products in the market position. In addition, because of the appearance of the LED filament lamp and the traditional incandescent lamp, so some traditional light source production enterprises of the machine, the mold can be generic, which is not an advantage, bubble, stent can also be achieved. In addition, LED filament lamp products are relatively easy to break, increasing the cost of transport. Therefore, in general, there is no obvious advantage of LED filament lamp, the market is basically watching, try.

Easily broken and increased transportation costs

Xie Jinli, general manager of Chengdu thunder

In the consumer's view, the appearance of the LED filament lamp is not the difference between the actual and ordinary bulb, followed by the existence of a certain degree of damage in the transport process, to a certain extent, increased the difficulty and cost of transport.

High price

The coefficient of difficulty: * * * * *

In the price led consumer choice of the moment, LED filament lamp cost is too high, resulting in its price is not very close to the people, hindering its marketing. The cost of raw materials by LED filament lamp filament, LED drive power, glass frame, glass bulb, lamp standard lamp hardware, these structures, LED is the highest cost of the filament, filament cost about LED filament lamp cost 60%-65%. At present, the basic price of LED filament between 2-3 yuan, a whole lamp generally use 4 filaments
