Description
Technical field
The utility model relates to a kind of anti-sulfuration and halogenation and the LED light source with anti-oxidation function, belongs to LED light source skill
Art field.
Background technology
LED is more than coming out, in widespread attention and developed rapidly, is not had the advantage that point not with itself
Open.These advantages sum up and are: brightness is high, operating voltage is low, power consumption is little, miniaturization, life-span length, impact resistance and performance steady
Fixed.The development prospect of LED is extremely wide, currently towards more high brightness, more high weather resistance, higher luminous density, higher
Uniformity of luminance direction develop.
But reality is during production and application LED product, we often meet with, and " product sulfuration (comprises sulfuration, halogen
The contamination phenomenon such as change, oxidation) cause product failure " etc. problem, these problems all bring certain loss to client and manufacturer,
After there is vulcanization reaction, product function district meeting melanism, luminous flux can be gradually reduced, and substantially drift occurs in colour temperature.Its principle is: because of
For the support of paster LED be on the base material of copper silver-plated (silver layer can play shinny, the effect of reflection light), TOP LED is at high temperature
During welding, encountered sulphur or sulfur vapor, then can cause silver layer on support and sulphur generation chemical reaction Ag+S=AgS ↓, formed
AgS, the number of visual response amount, its color is yellow or black.Silver layer the most serious has all reacted, and spun gold ruptures, and causes
LED opens a way.It can be said that encapsulation manufacturer is almost talks sulfuration discoloration.
Content of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of anti-sulfuration and halogenation and has anti-
The LED light source of oxidative function.
The anti-sulfuration of the utility model and halogenation and the LED light source with anti-oxidation function, it comprises metal substrate the 1st, product
Support the 2nd, LED the 3rd, bonding wire 4 and packaging plastic 5, product support 2 internal being provided with is provided with on metal substrate 1, and metal substrate 1
LED 3, is connected by bonding wire 4 between two mutual LED 3, and product support 2 is internal uses packaging plastic 5 above LED 3
Encapsulation.
As preferably, the upper surface of described metal substrate 1 is sequentially depositing aluminum oxide, silver, aluminum oxide, titanium oxide, metal
The lower surface of substrate 1 is sequentially depositing copper and silver.
The beneficial effects of the utility model: the 1st, base material is chosen flexibly, can choose according to product performance demands, copper, aluminium, iron etc.
Metal, by the other layer of metal of physical method metal surface deposition or metallic compound, according to demand, can selectivity
Deposition, such as: silver can improve substrate reflectivity；Aluminum oxide can protect metal surface glossiness, prevents sulfuration, improves reflective
Rate；Titanium oxide holding surface glossiness, protection surface does not cures, halogenation, and oxidation etc. is polluted；Base copper contributes on substrate
Tin, bottom silver can protect metal substrate not to be contaminated, tin soldering effect in raising.
2nd, support processing technology is simple, can directly punching press injection mo(u)lding, be not required to electroplate, the series of complex work such as chemical medicinal liquid
Skill.
3rd, suitably processing in metallic substrate surfaces, effective can preventing sulfuration, halogenation, oxidation etc. is polluted, therefore light source
Can use under more adverse circumstances at higher temperature, improve product self performance further.
4th, by substrate surface process, it is possible to achieve some seem very difficult technique, such as: at base metal
Aluminium, copper, the upper surface of base plate routing such as iron, bottom scolding tin；Realize that equivalent conventional patch production uses.
