Now LED lighting can be regarded as one of the indispensable lighting products. And LED work light bar are widely used in work place. You need to pay attention to the following six aspects when you are buying LED work light bar.

1. FPC quality. FPC is divided into two kinds: polygon and rolled copper. The copper foil of polygon clad is projecting, and then look at the FPC connector from the pad, it can be found out. While the rolled copper is close with the FPC and even can be bent and will not appear pad off phenomenon. Polygon clad pad will appear if it is bent too much, and when the temperature is too high, it will result in the maintenance pad off.
2. The surface cleanliness. If work light bar is using SMT technology, its surface cleanliness is very good. Do not see any impurities and stains. However, if the use of hand-welding process to produce copycat version of LED lights, regardless of the surface cleaning, there will be residual traces of stains and cleaning , while there remains in flux and tin slag FPC surface.
3. The solder joint. Good quality LED lights produced by good auto light bulbs manufacturer is using SMT chip technology with solder paste and reflow processes of production. Thus, the solder joint of LED work bar is the relatively smooth and little the amount of solder. Solder joints are a circular arc extending from pads of the FPC to the LED electrode. While the amount of solder joints of knock-off products c of LED lights is uneven, mostly a dot wrap welding foot, and there will be varying degrees of tin tip appears, which is a typical phenomenon of manual welding.

4. The packaging. Regular LED lights will use anti-static packaging trays volume, usually 5m or 10m roll, and then use anti-static moisture-proof outer bag sealed. The knock-off products because of the cost savings, they use recycled roll tray. Then there is no anti-static moisture-proof bags, look carefully roll trays can see when you look there are traces of clear labels and scratches.
5. Look at the label. LED lights with regular bags and roll tray above will have a printed label, instead of printing labels. The cottage version of the label is printed, and specifications and parameters are not unified.
6. Annex. Regular LED lights will be accompanied by instructions for use inside the box and lights with specifications, while also equipped with LED lights with connectors or deck; cottage version of the LED lights inside the box without these attachments because some manufacturers try to save material as much as possible.
 

Whether the auto light can work properly has a direct impact on the safety of our driving at night, so we need to pay attention at the purchase of car bulbs. Auto lighting is mainly composed of three parts: lens, reflector, and car bulbs. The design of lens, reflector and reasonable location with the light bulb are the key factors directly affecting the quality of lighting products.

1. View certificate
Product certification is also a product quality assurance, of course, we should also pay attention to see the company name, address, telephone and view implementation standards of product.

2. Do not just look at the price
Because for a light bulb, its price is more important than quality, so it's better to buy in a regular store at the time of purchase.

3. Check the bulbs
For automotive headlamp products, we should see whether the light-shaped cut-off line is clear, neat; see whether there are defects on the light appearance, and whether the surface is smooth; bulbs should be the national standard automotive products bulbs.

4. Buy products from well-known manufacturers
Choose to use the automotive lighting products produced by well-known auto lighting manufacturer, light bulbs can use the product made by large-scale regular light bulb manufacturers.

Matters need attention:
1. Lamp brightness is the most easily concerned lighting safety factor. The farther, wider the automotive lighting illuminates, the more secure, which involves the effective lighting problems. Although low quality automotive bulbs feel very bright, but they do not project onto the region required for lighting, but also produce glare to influence the oncoming vehicle. Within the scope of regulation, higher brightness lighting allows motorists to earlier discover security risks.

2. Precise positioning of the filament is an important factor for quality auto bulbs. Currently, we often see vehicles on the road emit blinding light, impacting on other vehicles; the reason is the lack of filament positioning technology.

3. The color decline is showed that the bulb brightness gradually is weakened with the use of car lights, this is a normal physical phenomenon, but the lights dimming will easily lead to accidents. We can choose high-quality light bulb to slow color decline, and prolong life. Once the light is dimmed, then it should be replaced, you cannot change it until it is broken.

4. Color temperature refers to the color of the light. The color temperature of most car bulbs on the market is about 3200K, yellow, dim light will make people naturally want to sleep, which will bring accidents. And white light will make people stay alert and awake.

Whether car headlights, fog lights or tail lights play an important role in driving safety, but the material determines the damage probability in the collision is quite large, then they will need to be replaced. However, the car led lights sold on the current market have many fake and shoddy products, which requires the car owners keeping your eyes open, to avoid buying fake pieces to endanger our traffic safety.

1. See the appearance
Generally the counterfeit headlights are rough work, there are more burrs on the corner, the manufacturer logo is blurred, or even none. Installation interface is not so seamless. Again look translucent surface of headlights, the glass surfaces of fake pieces are generally not transparent, and you cannot see the bulbs, reflectors inside, and there may have impurities. The regular headlights don't have such problem. Tail lights are the combination light of a variety of colors, the color of false light is generally not correct, too light or too heavy, and some shoddy products fade, the lamps having this situation certainly have quality problems.

2. See the inner components
You can see whether the inner parts of the lights are good or bad by simply opening the light. Generally shoddy lights will illuminate divergently and have no rules due to poor reflectors. The brightness of the same two lamps is not likely the same. However, the authentic auto lights do not exist such a problem.


3. See assembly
As the abrasive tools of shoddy auto lights are produced by imitating genuine light, but there still will have some differences, so it will not so seamless after being assembled, prone to penetrate water in the rainy days, which indicate that the car lights have quality problems.

4. Make a comparison
The simulation degree of counterfeit parts is still very high, so the above method is still difficult to distinguish between true and false, then you need to compare with the headlights removed from your car. Generally the identification and material of face auto parts are possibly to be distinguished in contrast.

Finally, the study of the above points is not enough. You should choose a reputable auto lighting manufacturer and repair shop, this is the most important. The simulation level of some parts is incredible, so it is better to choose good businesses and repair shop, to prevent fraud. Of course, their prices may be more expensive, but we cannot be sloppy in front of traffic safety.

Taifeng (VLK) Lighting Co., Ltd. has our own VENTURE LIGHTING KOREA manufacture, R&D, and the global selling authorization. At present, we are the only one automatic equipment line of America VENTURE and all the equipment are introduced by KOREA.

From the introduction of the production line, we adhere to the application of high quality, has been in use the strict standard of "VENTURE LIGHTING KOREA" to monitoring management. We are not only producing the customized product from Korean companies monthly, but also external supply the TF series and VLK series ordinary bulbs.

We have 14 units production equipment, the operation procedure is as follows: After put the quartz tube into the frame (which used to put the material in it) - High temperature to form spherical - Tube Cleaning - Fill xenon - Tube sealing. It is all processed according to the preset operation, so it can ensure the high efficiency and eliminate the unstable factors.

Compared with the other equipments, the introduction line of VENTURE has its own advantage, such as:

Automatic feeding:

The worker just needs to put the quartz tube into the material frame, and supervision it.

The function of the quartz tube:


Use high-purity (99.99%) automated pouring Argon to clean the quartz tube. After the quartz tube with high temperature being to the bubbling type, the domestic equipment generally applied Nitrogen (3%Oxygen) to clean it, but our equipment is adopt the high-purity(99.99%) argon to clean, in order to avoid the light bulb tube to oxidation.

Constant-temperature the liquid Nitrogen tank:   

When pouring the xenon, the equipment of the constant-temperature liquid nitrogen tank will ensure each bulb in the same environment, so the xenon will not turn into gaseous to volatilization. The other equipment, need to used the manual control but it will be not in the same degree of volatilization, this will lead to the car tail lamp brightness, color temperature is different.

The original creation of quartz tube inside and outside the pinhole of vacuumized technique.

The Adopt-2pa atmosphere pressure to vacuum sealing to reduce the possibility of oxidation.

P.S. When sealing for the xenon, there are some factories in China possibility will be flooded without vacuumized.

High temperature dehydroxylation technology.

Hight temperature oven clear the hydroxyl of quartz, through our equipment, the hydroxyl content of quartz tube is less than 3ppm. (≦3ppm).

There other factory have their dehydroxylation is ≦15ppm, (some of them even haven't this technique!) it must get the bulb turn into yellow, fog and even risk of the cracking.
