How light bulbs are made years ago?
2012/5/17
One hundred and thirty years ago , Thomas Edison completed the first permanent effective control bulb in brightness range. Some incremental improvements along the way, illuminates the fundamental technologies of Edison, the planet actually has. this will change. We are at the beginning of the revolution in solid-state lighting, which eventually replace the bulbs with Edison lighting solution is based much more energy efficient. provided strong LED lighting at some point replace almost all in the selection of a huge multi-billion incandescent and fluorescent lamps in use in the vicinity of the planet. In fact, as an action in this direction, President Obama made in June of last use stricter criteria for the new lighting will be the phasing. Far from light bulbs (the previously banned in the elements of Europe)
To recognize how revolutionary Lumination LED lamps are and why they are still expensive, it is instructive to look at how they are produced and also to examine it in the manufacture of incandescent light bulbs Lumination. This article examines how to Lumination bulbs are contrary to this process made so that a common explanation in the production that Lumination LED lamps.
So you can first take a look at how the bulbs are manufactured Lumination. You will find that this is an instance of an automated process traditional commercial refined in more than a century of experience.
Although no differ Lumination bulb species in form and performance, they all have three main parts: the thread of the piston and the base. The tungsten filament is produced. all quite fragile, tungsten filaments can withstand temperatures of 4500 degrees Celsius and higher. The son of the compound or delivery of the product are usually nickel-iron metal. The cable is immersed in a solution of borax to produce the cable much fused glass. The piston is made only for cutting and consists of a mixture of gas, generally argon and nitrogen, which reinforce the existence in the filament. Oxygen is pumped from the tuber and modified with the gas. Normalized background, the whole assembly in place. The soil was recognized for "Edison screw base." Aluminum is isolated in the outdoors and the cup to his chest in the database.
Quote of the hand bulb production Lumination develops is now almost entirely automated. First, the filament using a method such as drawing, in which tungsten is mixed with a binder and pulled through a nozzle (to form an opening) for a wire well recognized. Next, the cable in the vicinity of a panel is material of a mandrel known, so that it can only flow in the right form wound, after which it is heated in a procedure recognized as very wound annealing, wherein the cable softening its frame and creates much more uniform. The mandrel is then dissolved in acid.
Second, the filament wound current inputs is connected. Lead in son have spot welded hooks at their ends which are pressed over the surface in the filament, or may, in larger onions.
Third, the cup onions or enclosures are designed with a tape machine. shortly after the heating in an oven of the same, a continuous belt moves along a conveyor belt cup. Oxygen nozzles aligned exactly the cup blows through the holes while the conveyor belt to develop into molds envelopes. A tape recorder at the best price can move more than 50,000 bulbs per hour. Soon after the envelopes are blown, then they are cooled to reduce the gap of the machine tape. Then, inside the flask coated with silica to remove discovered the glare from a bright, filament. The title and power are then stamped out most of the box every time.
Fourth, the bottom of the flask are also using forms. It is produced with recesses, while in the shape of the screw to be sure, he can quickly align the connector on the device Lumination.
Fifth, if the thread base and bulb are made, they are equipped with machines. First, the filament is attached to the rod, with its ends clamped two power inputs. Then, the oxygen is evacuated inside the piston, that although the housing is filled with the mixture of nitrogen and argon.
Finally, the lower and the lamp is sealed. Slipping back to the finish line in the bulb for this type of cup that no other product is necessary, it is to keep together. Instead, their line shapes allow both parties together to perfect, instead of lead in the bottom son touches aluminum to ensure proper electrical contact. Shortly after the tests, the lamps are placed in their offers and delivered to the consumer.
Incandescent lamps are evaluated for the presence of two light and power. one can easily deliver quick results, selected bulbs are screwed in racks verify the existence and lights at distances much larger than normal. This gives an accurate estimate of how long the lamp in the last common conditions. Screening in all production and plant life, as done in some impartial testing facilities. The typical existence in the common house bulb is 750-1000 hours, on the basis of power.
Lumination LED lamps near semiconductor devices are built in the solid state, so that production is closer to the one used for digital documents, such as to produce PC motherboards.
A light emitting diode (LED) has a high power electrical circuit condition, the exposure generated be very by the movement of electrons in a semiconductor material. LED technology can be regarded as close to the 1960 because the last one, but were for the first 40 years, many LEDs are mainly used in electronic products to replace miniature bulbs Lumination. Within the last decade, advances in technology, while ultimately stimulates the production of abundant Lumination LED begin to compete with the critical Lumination bulbs bulbs and fluorescent tubes. As with many technologies, since the manufacturing cost is, each successive LED technology also improves the quality of exposure, every watt of output power and thermal management.
The PC market properly suited to the manufacture of LED lighting. The process is not an entirely separate matter too much to generate a PC motherboard. Companies manufacturing the LED itself is usually not while in the field of lighting, or it may be a small part of society. They tend to semiconductor body, the crank were satisfied with the product, so the cost will be deleted on high-efficiency LED when a bargain is preserved, while in the last 15 years.
LED lamps themselves are of high prices in the component, since it carries a plurality of LED lighting for a large area and not the narrow beam, and the price of the installation requires the general price. In addition, production orders, with the arrays of LEDs are much more likely to defects of objects.
An LED light quality is composed of 4 elements: a printed circuit board LED, a heat sink, a power supply, and an envelope. The lights start as a bare printed circuit boards (PCBs) and high brightness LED factors separate factories, which are used in the manufacture of these components, specialized people. LED-factors by itself produce a touch of heat, so that the PCB is used in lighting something special. in the report very even non-conductive epoxy and glass fiber sandwich, the circuit on an aluminum foil, which functions as a radiator is disposed.
The aluminum in PCB LED lighting is used covered to a non-conductive trace and copper interconnects have the circuit type. Solder paste is then used, while in the most appropriate locations, after which the surface of exposure mounting technology (SMT) products location of small LED elements, control circuits and other elements of the extremely large disk speeds.
The round shape of the conventional lamp Lumination implies that most LED boards are circular, so that for ease of management in many small round printed circuit boards can be processed in a larger rectangular plate, the mixed Automated SMT machines. look at it as a cupcake tray down shift to a camera connected to a conveyor belt, then the finish line, the cupcakes are a free man broke into the shell.
Let's take a look at the output, replacing each bulb LED light bulb to a quality in common with an Edison screw. You will see that this process can certainly quite different in the highly automated processes used to be to create our light bulbs. And regardless of what you can imagine, men and women are still very much a bargain a mandatory part of the production process, and not only for testing and quality assurance.
Once the larger leaves of the LED boards are connected by a reflow furnace (BOF a hot melts the solder paste) is passed, they are divided circuit boards in the person of young son and energy welded manually.
Those low-power supply is housed in the system during the light quality of the light bulb through a similar process, or can be supplied entirely by an additional investment. In any case, the output measures would be the same through the first PCB SMT lines, then it goes to a certain package online dual-manual (DIP) collection assembly exactly where a long line of workers are complex: one element at a time. DIP refers to two parallel rows of leads from the sides of the package. DIP elements consist of all integrated chips and chip outlets.
During melting, the LED lights often more extensive than incandescent or CFL, and demand a lot less than half the energy they need some kind of passive heat sink to keep the high-power LEDs from overheating. The LED circuit that 1.6 to 2 mm thick aluminum, can be prepared, for generating heat in the dozen factors to LED lamp frame material and thus maintain the temperature within the controller. Aluminum-backed boards are sometimes referred to as "metal key boards," and if the product produces light-conducting coating is electrically insulating. The aluminum PCB is screwed into place in the interior of the cooler, the halving in the bulb LED light quality taps.
Then plug the board of the energy in place with adhesive is fixed. The low power supply converts 120/240V AC power sector in a certain tension to reduce (12V or 24V), while it fits into the cavity at the back of the aluminum-PCB.
Shell assembly is to lock the trunk in a place with screws. A plastic shell and provide energy management protocols in the use of the device and heating element LED circuit. The ventilation holes are together, so that the hot oxygen escape grouped. Assembly for wiring electrical outlet must be soldered to lamp holder son. Then, the shell is fixed.
Then, the finished quality LED light is sent to burn-in and greater control. The burn-in control normally takes 30 minutes. The LED bulb powered EV is then seen as a good deal completed, if it works properly and burned for 30 minutes. It can also be a test for leakage of high voltage and the distribution and use of energy and energy of the test element. Examples in the production function for high voltage leakage, power consumption and energy cost components (efficiency) into account.
Lamps with a crimp-filled action taken recently by the bottom material squeezed on the spot, are provided with bar codes and identified by lot numbers. Safety labels are on the outside as well used as the light bulb with information along the lines of the manufacturer and model number will be colored. Finally, all that remains to be placed in clear plastic LED, which can be glued in place.
After a final check to ensure all elements are completely different dense in the Lumination LEDs, then it is packaged in individual boxes, and the lamps are supplied.
Thus, in circumstances that you can understand why Lumination LED lamps as high prices today, this explanation of how they are produced and how it compares to the production of conventional light bulbs Lumination should ask for help. But it also shows decline, why the price quite significantly more than the few years after. Just because the price for the production of other semiconductor-based products has emerged as a result of standardization, automation, and other important steps in the production curve study has been made, some inexorable forces produce similar reductions in production costs Lumination LED bulb.
