Plastic cement 3 adopts high temperature resistant, and the PPA plastic cement that reflectivity is high is mainly for enclosing silica gel 7 and structural member, adopts equipment injection mo(u)lding;
Gold thread 4 uses automatic wire bonding machine, the circuit of the both positive and negative polarity of LED chip 5 and product is welded together, make LED chip 5 and the circuit of pcb board form path, make LED chip 5 luminous thereby pressure drop can be passed to LED chip 5 in the time adding voltage to pcb board circuit;
The luminous component that LED chip 5 is product, adopts the bonding mode of elargol LED chip 5 to be bonded in to the center on copper post 1 surface;
Lens 6 adopt plastic cement high temperature resistant, high transmission rate, adopts injection moulding extrusion modling, and its effect is structural member;
Silica gel 7 adopts that two components are high, light transmittance, the silica gel that high temperature resistant, cementability is good, fills up support after mixing, and LED chip 5 and air insulated are ensured to the useful life of LED chip 5 and gold thread 4 are not subject to ectocine.
Although the utility model is described with reference to the above embodiments; but those of ordinary skill in the art can very clearly recognize that above embodiment is only for the utility model is described completely; wherein can make various changes and revise and not depart from a broad sense the utility model; so not conduct is to restriction of the present utility model; as long as within the scope of connotation of the present utility model, variation to above-described embodiment, distortion are all by within falling into the protection range that the utility model requires.
