LED the filament lamp after four consecutive years of development, the production breakthrough N hundred million in 2016. Filament lamp adopts high voltage LED HVLED and small current drive technology, innovation the technology of LED light source and the design of lamps and lanterns. LED lamp filament technical threshold is not high, and we actually shot vigorously promotion, popularization of LED filament lamp design and manufacturing technology, incandescent dengpaoan and consumer electronics products factory all over the world are easy to join production LED lamp filament. 9 billion years all over the world need to incandescent lamp, energy saving save electricity safety LED filament lamp can aid the upgrading of incandescent lamp, completely meet the needs of the world market. LED lamp filament core technology is LED filament and constant current power supply chip. The LED lamp filament is by 'rigid straight silk filament + LED constant current drive power supply + + glass bulb, lamp holder glass core column'. In 2017, the standard model could be reversed? A new generation of ceramic base foundation arc LED filament, the metal ink LED filament, the metal base IC filament, and can be arbitrary curved shape flexible LED filament was born! And into the industrial production. Metal matrix IC filament may make the filament lamp save configuration of constant current power supply now, perhaps change the filament lamp filament layout design. No AC/DC power supply AC direct drive LED filament light also in the making, LED a filament lamp is a new technology revolution is under way! Arc heater and graphene filament straight silk filament LED lamp light distribution curve into malar rash, open the straight wire LED lamp filament, the middle of the light will appear dark space and the bright. And arc of silk filament LED lamp light distribution diagram is a full moon, wire arc LED filament light there would be no light in the dark area below. Bring about figure 1 arc filament light distribution curve in full moon metal cornerstone ink ene filament is on one side of the metal substrate binding LED lamp bead chip, coated yellow green fluorescent powder, make a blue LED lamp bead, blue yellow green phosphor after a white light. Metal base material is coated on the other side of the graphene, the use of graphene coating to metal substrate heat radiation soon coming out, improve the LED lamp filament relying only on helium heat conduction, the single way of using glass bulb heat emission. Bring about figure 2 TaoJi curved filament bring about figure 3 metal cornerstone ink ene filament IC filament IC filament is the binding constant current IC chip directly on the filament base board, constant current IC in filament substrate and the N series LED lamp bead chips directly into an organic whole, become a new electronic LED control filament current filament. Due to the mass production of LED lights, the parameters of the discreteness is very big, even when we are in LED filament production efforts pairing, still can't guarantee the batch production of filament, VF of each root are exactly the same. The VF have slightly difference a couple of leds combined filament in a light bulb, by a constant current power supply, VF small filament current will get more, over time, this small VF LED filament light failure will occur. This is the LED lamp filament a recessive cancer, is also a COB filament of a difficult technical problem to conquer. The constant current IC chip directly combination the filament, and LED lamp bead chip binding together into a new generation of COB filament with IC. LED filament was produced by the LED assembly house a passive COB device to add IC constant-current control chip, IC filament by electronic LED, filament from passive devices jump into a new generation of active electronic components! LED filament so can control electric current to flow and spikes are constant! The VF without demanding anymore! Maybe LED lamp filament and eliminate the AC/DC constant current power supply, with IC LED filament can make LED lamp filament real electronic incandescent lamp! Bring about figure 4 metal matrix IC filament internal structure schematic single channel two port constant current control IC single channel port constant current control IC is a highly integrated constant current power supply internal chip, it consists of fine-tuning, reference voltage, regulated power supply, temperature compensation, over temperature protection, current sampling, op-amp, constant current control, MOS of function modules. Simple to use, can be directly driven high pressure LED lamp series, without debugging, no sampling resistor, application circuit is very simple. Chip internal limit constant-current, fixed output 10 ma, ma, 20 ma, ma current 12. Chip built-in 600 v MOS. Application of line EMI problems. The built-in thermal protection. Applied to IC filament is very convenient, but constant by N in the series of LED lamp bead chip HVLED filament current. Also can be widely used in various types of optical engine. Bring about figure 5 on both ends of the application of constant current control IC figure LED filament light starting from the date of birth will grow in constant technical innovation, expansion in the constantly improve the automation of production process equipment. Now both filament and drive power supply chip technology are in urgent need of a revolutionary innovation! LED lamp filament are marching to the automated production of high-speed! Welcome to the world market LED filament light! LED the filament lamp to meet 2017 chaoyang will tear! All LED lamp filament practitioners must keep pace with The Times! Advance to follow the trend of technology innovation.
