Background technology
The principle of luminosity of LED is by compound semiconductor, by the combination in electronics and hole, superfluous energy by electric current
To disengage in the form of light, reach luminous effect.For visible ray light-emittingdiode wavelength in 400-700 nm.It is existing
Some LED illumination light sources are broadly divided into two kinds of direct plugging-in and patch-type.
Straight cutting LED is also referred to as plug-in unit light emitting diode, is a kind of partly leading for solid-state that can convert electrical energy into visible ray
Body device.The encapsulation of direct insertion LED is in the form of embedding.The process of embedding is first to inject liquid epoxy in LED forming cavities
Resin, is inserted into the good LED support of pressure welding, allows after epoxy resin cure, LED is detached i.e. from die cavity in being put into baking oven
Shaping.
It is substrate with soft pcb board that paster LED is, high brightness paster LED is uniformly arranged as illuminator, illuminator
In stripe shape pcb board front, it is connected with each other using water joint, is adapted to SMT processing, reflowable weldering, adopting surface mounted LED is solved well
