Description

The assembly method of LED silk
Technical field
The present invention relates to a kind of assembly method of LED silk.
Background technology
Traditional LED LED chip is fixed on a cooling stand, the negative electrode of chip and the anode positive and negative electrode to support is connected with gold thread, stent electrode passes into electric current, LED chip is made to send blue Single wavelength light, this blue light carries out the conversion of spectrum by the fluorescent glue covered on chip, is mixed to form white light.Support generally adopts the plastics of engineering plastics or band metal heat sink, then increases its light extraction yield by bottom reflection, or shaping or band secondary optical lens changes the refractive index of internal material by silica gel, thus increases its bright dipping.Traditional packaged type, light utilization efficiency for LED chip is quite low, particularly fail to make full use of the all-round light of LED chip, by by LED on rectangular transparent pottery or glass or carefully narrow metal substrate, periphery superscribes fluorescent glue, make strip filament, what can increase LED goes out optical range.This LED silk is applied to bulb lamp more, with the lighting angle feature that it is larger, replaces conventional incandescent lamp.
LED silk surface fluorescence glue vulnerable to pollution, causes the decline of the light extraction efficiency even aging blackout in glue face; The material structure of LED silk encapsulation is also more fragile, very easily damages in production operation, therefore needs the electrical connection schemes of a design convenient and efficient to solve the assembly problem of LED silk.
The filament assembling of existing LED silk lamp adopts spot welding mode, is directly fixed on by LED silk on a three-dimensional bracket with conductance silk, if filament and bulb axis angled, photodistributed uniformity can be improved.During welding, first want fixed support and filament, and be that predetermined angular contact with the conductance silk on support in precalculated position by the pin of filament, with spot-welding equipment, contact site is welded, after being soldered two pins of a filament, then support is rotated to an angle, repeat filament and place and welding, meanwhile, mode, the positive-negative polarity of the rotation adjustment LED silk of support to be coordinated at solid space according to the string of LED.This frame mode, packaging support, filament, welding machine need from stereo multi-dimensinal degree compounding practice at interior materials and parts, frock tool and equipment etc., add that the intensity of LED silk itself is not high, cause quality of welding spot to be difficult to ensure, fraction defective is high, automatic processing device structure also can be quite complicated, development difficulty is also high, drops into huge; To operating personnel require high, operation easier is large, efficiency is low; Supporting structure has also placed restrictions on the increase of LED silk quantity, otherwise can hinder welding job, and therefore the power of LED silk lamp is also limited.In a word, this mode is unfavorable for batch production large-scale production.
Also have the mode of people's imagination combination hub, be directly inserted on combination hub by LED silk, eliminate filament welding sequence, assembling quality efficiency is also high.But glass ball bulb lamp internal components when glass-dead seal needs the high temperature bearing hundreds of degree in short-term; Operationally, filament leg not only bears the task of electrical connection to LED silk lamp, also will undertake the function of heat loss through conduction; LED silk also will bear electric and magnetic oscillation to a certain degree.With regard to these several respects, combination hub mode cannot be able to reliability application in practice.
