LED filament lamp will not become the mainstream of the bubble type light source?

Along with the foreign demand for LED filament lamp is more and more big, due to the large angle of the traditional LED incandescent lamp filament lamp has popular habits and familiar emitting form, the application group is touted as "retro" complex, so long as the LED filament lamp incandescent lamp has found its application in "". Also because of the production process and LED incandescent lamp filament lamps for lighting manufacturers are similar, has been engaged in the production of incandescent lamp, turned to the production of LED filament lamp into the field of application in production, is undoubtedly a very simple thing. With the LED filament lamp from the theory to the reality of the lighting products, from decorative applications to functional lighting applications, the demand will be growing, at present, to enter the field of manufacturers is said to have more than 600!

Then, in the technical composition, because the filament lamp filament in the closed environment, and the area of the substrate of the LED filament is too small, the decline of small, long life requirements, the practical application of the heat is as designed? Are there any means to ensure that the technical specifications of the LED filament lamps meet the quality requirements of the application? November 22nd at 8 in the evening, the LED industry elite alliance WeChat group on the future of LED filament lamp depth dialogue, the following is the dialogue:

[issue]: LED filament lamp will not become the mainstream of the bubble type light source?

In terms of LED filament lamp technology and technical requirements, LED filament lamp components constitute a:

1 transparent glass cover;

2 solid (positive) or flip (flip) filament;

3 metal material (iron, aluminum, etc.) screw plug;

4 power.

Technical requirements for LED filament lamps:

1 no Blu ray overflow;

2 high color rendering (Ra > 90);

3 no strobe;

4 high light efficiency (110~125Lm/W)

5 light emitting angle (320 degrees)

6 replacement (traditional interface, E14, E27, etc., the size of the shape, the current A60, C35LED filament lamp is mostly)

7 excellent heat dissipation (a small decline, long-life requirements)

In the discussion, it is proposed that since the current LED bulb group has reached the basic requirements of the application, the price has reached an acceptable level of the general public, is also a spherical light, why must we toss LED filament lamp? Presenter Chen Bingquan responded: contrast from the light quality performance of LED and LED filament lamp bulb the hand, say that if their application technology is also mature, its performance is the German BMW automobile and domestic QQ car -- a comparison with the product of a kind, not in the same grade, quality requirements and different performance, price and application places is not the same, some applications is not ordinary LED bulb to meet the application needs, this is the charm of LED filament lamp and a bright future. There is no doubt that there are several indicators of LED filament lamp is very far fetched, such as heat and light, it is the LED substrate filament lamp based on the limit of the area is too small. In order to filament lamp with the development of the inherent idea of breaking LED lighting is very important, personal opinion, improve the structure of LED filament filament lamp, the LED filament lamp adopts filling inert gas to heat radiation to the gap with the design effect in the practical application of great. Because LED is used in filament COB package chip, using some effective technical means to reduce fever or rapid thermal conduction is the LED filament lamp with low light decay, long life assurance, optimization, the shape of the substrate material such as substrate selection, power split mode etc..

No flicker on LED filament lamp, presenter Chen Bingquan believes that LED filament lamp has the advantages of small size, installation space is small, the installation space is limited to the components size requirements are very stringent, the current can be matched with small power, power supply products small installation space only meets the requirements of high voltage linear. Due to the high voltage linear in the current fast through the cause "hole" effect, in the premise of compensation technology lack the technical means of fine, in the scale of production is very difficult to do without stroboscopic, which engaged in high-voltage linear manufacturers for absolutely no stroboscopic do not have absolute solution, only the use of technical means to "hole" in effect, the strobe control in a certain range.

The outlook for entering the LED filament lamp applications discussed, Xingbao Aurora lighting general manager Li Zihao LED believes that there is a rapid development of filament lamp, has the advantage in the future cost and personalized. The opposite presenter Chen Bingquan's view, if the performance of LED filament lamps of curing is very good, but will fall back to the traditional application fields, such as general lighting, retro decorative lighting, crystal chandeliers, lanterns and so on, this is the unified LED filament lamp of high difficulty, or at this stage for LED filament lamp, decorative significance is greater than lighting function in terms of the current technological development, to meet the lighting function is to point the day and await for it. CREE general manager Liu Hui believes that on the LED filament lamp filled with gas to achieve the purpose of heat dissipation, the heat

The form can not fundamentally solve the problem of heat, only slightly better, but the decline is still quite large. In the project application also exposed LED filament lamp immediate problems in several projects on Party A: I have rejected the filament lamp, the reason is the high price, when light does not look good, not the decoration function, the final selection of the bubble tip patch.

During the discussion, the general manager Yi Zhihui made a comprehensive description of LED filament lamp: LED filament lamps and light attenuation problem is small to see, although now enter the LED filament lamp manufacturers, but
