Decorative Vintage Led Lamp
Decorative vintage led lamp is also called special decorative vintage Edison led light bulb. Because usually is a Led light bulb, but it is not a normal led bulb, it is with special shape of glass, special led filament design, special color of the glass, it is mainly used for lighting decoration, so we call it special shape vintage led light bulb as special decorative vintage Edison led lamp.
Special decorative Edison led lamp is usually has a big size, much bigger than normal led bulb. The glass bulb is made by hand, not by automatic glass bulb machine, because it is much big and with an irregular size. The glass is high quality hardness glass, and should be thick enough, for safe shipping. Dongguan bofa lighting produce the glass bulb by us, we have a big workshop for it. First, we buy strong and big long glass tube from professional glass factory, we heated the glass tube by a very high temperature, and then our worker blow it with a long tube to make the glass tube to a special glass bulb shape with a tooling, the tooling is with a decorative vintage led bulb shape. After the glass bulb is finished, our worker will polish it, because there are some scratches or salient point on the glass bulb, after polishing, we take the glass bulb to electroplate factory to make the glass bulb with different color, such as amber color, gold color, silver spots color, semi-dark color and so on. Then a special decorative glass bulb is finished.
After the glass bulb, it is the glass stem, glass stem is in the center of the glass bulb, it is the support for led filament, setting to lamp base. For vintage Edison led lamp, the glass stem must be strong and thick enough, because it long, it is easy to break during transportation if the glass stem is not thick and strong. We produce the glass stem, we have more than 20 automatic glass stem producing machine, our glass stem is two times thicker and stronger than that from market, this ensure a safe transportation of the decorative led lamp, so far we did not receive any broken complaints from customer. Of course the packing must also very good.
After the glass stem, it is the filament design. Because it is special decorative vintage Edison led bulb, the most important is the glass shape and filament design. There is hard filament led and soft filament led, we use them to make different design, for example, spiral filament design, squirrel cage filament design, loops filament design and so on. Flexible soft filament led is soft and flexible, so it is more easier to make different and difficult design, and flexible soft led filament has different length, the longest we can do is 100cm length. Because it is decorative led lamp, so the color temperature usually is 2000-2200K, and the lumen output is not much high, usually it is 120-300lumen, wattage is 3-5W. So that people can see the filament without feeling dazzling. We can make the led filament design according to customer requirement and customer design artwork. We dongguan bofa lighting company has more than 120 automatic welding machines for welding led filament.
After finishing the glass bulb, glass stem and filament design, we assemble them together to make special decorative vintage Edison led bulb lamp.
All of our decorative Edison vintage led lamp is inflated with helium gas, because helium is a kind of inert gas, it can resist the high temperature from led filament and power, it do not have any affect to filament led also, not like oxygen, which can oxidize the filament led, it is a kind of protection to led filament. Also, when the lamp is lighting on, the filament will create some heating, the helium gas will flow in a circle inside the decorative led bulb when it is heated, and take the heating to glass, glass will transmit the heating to outside, so helium is also an effective heat sinking material. Heating is a big problem to decorative vintage Edison led bulb, if the heating can not be sinking efficiently, the filament led or power maybe damaged. However, before inflating helium gas into the glass bulb, the glass bulb must be vacuum, we dongguan bofa lighting has the most advanced vacuum machines. Why should the glass bulb be vacuum before inflate with helium gas? Because normal air has all kinds of material in it, such as dirty, oxygen, moisture and so on, the dirty and moisture will change to fog when the decorative vintage led lamp is lighting on, the heating will change the dirty and moisture to fog, and the fog is on the inside surface of the glass bulb, this makes the vintage led bulb much bad looking!
Package for vintage decorative Edison filament led lamp. Because decorative led light bulb is big size glass bulb, so it is fragile, the package need to be safe enough. For small size of decorative light bulb, the size is smaller than G150(diameter150mm), we usually use bubble wrap pack the bulb first, then put it into a box, the box should be about 3-5mm bigger than bulb, so the bubble wrap can stay soft and elastic, which could be able to protect the bulb properly. If the size of the decorative vintage led light bulb is bigger than G150, for example A165 decorative vintage Edison led light bulb, then we have to use foam package, the foam has a square shape that is according to outside brown box, the size is about 2mm smaller than outside brown box; The shape inside of the foam packing is according to the shape of the A165 decorative led lamp. The foam packing must be soft enough, not too much thick, nor too much thin, but has enough protection to bulb. After packing the big size decorative led light bulb with foam, put the foam with bulb into outside brown box. Foam packing is a little expensive, and the size is a little much bigger than bubble wrap packing, so the volume is big. For big size decorative led light bulb, we usually ship by sea shipping, of course packing the carton boxes with pallet packing. Usually, one pallet has a size of 1.0M wide, 1.0M length, 0.12m high, after packing with big size decorative led light bulb, the total size of the of the pallet is about 1.0*1.1*1.5M, 1.5M is the height, the height should not be more than 1.80M, because container has a height of 1.80M, if the pallet packing is higher than 1.80M, we can not put it into container. Pallet packing has an effective protection for big size decorative led light bulb during transportation. However, for a full container shipping, we still suggest not packing with pallet, because the whole container only load big size decorative led light bulb, no other heavy goods, no change of the container, shipping company will ship the whole container directly to customer warehouse, and then customer unload the goods. So FCL shipping usually do not need pallet packing. However, LCL shipping must be packing with pallets, because big size decorative led light bulb will be shipping together with other goods in one container, the other goods maybe much heavy, which may cause damage of the decorative led bulbs.
Color printing box. The design of the color printing box is from customer design box artwork, with customer logo. However, because the print box is expensive than brown box,, the MOQ for printing box is 500pcs/item, so we always suggest customer order more than 500pcs each item, otherwise the cost of the printing box is very expensive. However, if customer has a guarantee that there is following orders, then the order quantity could be smaller than 500pcs, we make the printing box more than 500pcs, keep some at our stock, use them for the following order.
