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, what are the development difficulties LED filament lamps are facing at this stage?

Problem 1: low yield

Compared to traditional incandescent lamps, LED filament lamps have higher requirements for 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. The defects of the bulb material also make the LED filament lamp easily damaged during the transportation process, and the process is complicated and low yield, so that the LED filament lamp can not be obtained by the manufacturers and consumers.

1. the process is difficult, 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.

2.structure, performance and price should be improved

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 key technologies, the mature of packaging technology and the improvement of sealing technology, the luminous efficiency, finger pointing, life span and cost of LED filament lamp will be improved to a certain extent.

At present, LED filament lamp needs to be improved in too many places. She is like a new "premature baby". All aspects are not mature, high cost, complex manufacturing 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.

3.small power, poor heat dissipation is a hindrance

Influenced by the production process, there are many problems in the LED filament lamp, such as high cost and the defects of the ball bubble material, there is a high damage rate in the process of transportation. In addition, the heat problem more LED filament lamp has become LED filament lamp into the common people of the obstacles.

Problem 2: high price

According to the market survey, the average retail price of a 3W LED filament lamp in the 28-30 yuan, the price is far higher than the same power LED bulb lamp and other lighting products, is several times higher than incandescent lamp, LED the same power so many consumers fall back LED filament lamp price.

At this stage, LED filament lamp market share of less than 10%. Now, LED filament lamp as a special product, restore the traditional tungsten filament lamp lighting feeling, has been loved by many consumers. But, LED filament lamp cost higher, light efficiency is low, application range is small, is also the next stage lighting manufacturers must face and look at the problem.

1.supporting materials to increase product costs

LED filament lamp market prospects are very bright, but at this stage to promote LED filament lamp existence difficulties are trapped in the lack of the high cost and high wattage makes LED filament lamp is currently limited to the application, the Lantern Market in addition, raw materials supporting but also increases the cost, because the filament lamp in specifications and shapes is not a standard, not the market volume plus, caused by supporting materials basically customized, high manufacturing costs.

2. LED filament costs are too high

In all parts of the LED filament lamp, the highest cost is LED filament, mainly in the complex production process, cutting cost is high; the production efficiency is not high, the low degree of automation, the cost down. At present, 3-6W filament bulb, all costs can be controlled at less than 15 yuan, of which LED filament costs accounted for half of the country.

3. LED filament lamp packaging more exquisite

LED filament lamp package is exquisite, every enterprise packaged light effect is not the same, LED filament lamp still has certain limitation in the power and heat dissipation, resulting in higher prices than ordinary light source LED.

Problem 3: small market

At this stage, the power of LED filament lamp on the market selling less than the basic 10W, which shows that the present LED filament lamp technically trapped in the heat problem, unable to achieve high power, also shows a short it can only cover the entire lighting product line, not widely, even played "nostalgia" brand, LED filament lamp market is a niche market, temporarily not into the mainstream.

1. consumer acceptance is low

In the current market of incandescent lamps and energy-saving lamps shrinking, LED lighting products are slowly being recognized by end consumers. But for now, the LED filament lamp market is still very limited, due to the application of LED filament lamp and power limited, LED filament lamp is accepted by the end consumer is not very high.

In addition, consumers do not know enough about the LED filament lamp, which many believe is an improvement on ordinary incandescent lamps.

2. the main demand comes from the project

Since the LED filament lamp is mainly used for lantern, its main demand comes from engineering lighting, so, general
