Abstract
The invention discloses a manufacturing technology of a low-power LED (light-emitting diode) lens. The manufacturing technology comprises steps as follows: preparation of synthetic resin: various resin materials are added to an extruding machine to form the synthetic resin; preparation of a pressing material: glass fibers or glass cloth is subjected to operations such as cutting, puffing, infiltration, drying and the like sequentially to form the pressing material; molding: the synthetic resin is placed into a mold to be heated and pressurized for molding; pressing: the pressing material for enhancing performance of the synthetic resin is added to the mold; lens surface treatment: a plurality of spherical grooves are evenly distributed and formed in the inner surface of a lens which is not completely cured. Compared with the prior art, the manufacturing technology of the low-power LED lens has the advantages that the halo phenomenon can be effectively eliminated through cooperation of the LED lens manufactured with the technology with an LED lamp, the illuminating effect of the LED lamp can be improved, and meanwhile, temperature resistance and light transmission of the LED lens can also be improved.
Description
Technical field
The present invention relates to a kind of manufacturing process of low-power LED lens.
Background technology
LED lamp is furnished with optical collector, such as reflector and lens, halation phenomenon may be produced when adding reflector and lens, namely yellow limit is produced around after adding lens when LED lamp emits white light, this is because most of low-power LED lamp is all select plastic lens, the absorptance long wavelength low-frequency light of plastics to the high-frequency light of shortwave ability is eager to excel a lot, this is the main cause causing halation phenomenon, and the LED lamp producing halation phenomenon can have a strong impact on LED lamp illumination effect, therefore, be necessary to do further research.
Summary of the invention
The present invention is intended to solve above-mentioned mentioned technical problem, provides a kind of manufacturing process of low-power LED lens.
The present invention is realized by following technical scheme: a kind of manufacturing process of low-power LED lens, comprises synthetic resin preparation process, various kinds of resin material is added extruder and forms synthetic resin; Moulding material preparation process, glass fibre or glass cloth are carried out successively cut, fluffy, to infiltrate and the operation such as oven dry forms moulding material; Forming step, puts into mould by synthetic resin and heats extrusion forming; Molding process, adds the moulding material for strengthening synthetic resin performance in a mold; Mirror process step, is not having the uniform groove arranging several dome shape of completely crued lens inner face.
Preferably, the extrusion temperature of extruder is 180-200 DEG C.
Preferably, molding compound preparation process also includes the kneading operation between resin material, and described kneading operation is between fluffy and infiltration operate.
Preferably, mould is metal die.
Preferably, also comprise enhancing step, add the auxiliary material strengthening synthetic resin performance further in a mold.
Preferably, auxiliary material comprise curing agent, promoter, diluent and surface conditioning agent.
Preferably, groove surfaces is provided with the coating for diverging LED light source.
Beneficial effect is: compared with prior art, the LED lens manufactured by manufacturing process of a kind of low-power LED lens of the present invention coordinate LED lamp effectively can eliminate halation phenomenon, improve the illuminating effect of LED lamp, temperature tolerance and the light transmission of LED lens can also be promoted simultaneously.
Detailed description of the invention
A manufacturing process for low-power LED lens, step is as follows:
Synthetic resin preparation process, various kinds of resin material is added extruder and form synthetic resin, the extrusion temperature of extruder is 180-200 DEG C, and the synthetic resin after extruding transports and enters in metal die.
Moulding material preparation process, glass fibre or glass cloth are carried out successively cut, fluffy, to infiltrate and the operation such as oven dry forms moulding material; Molding compound preparation process also includes the kneading operation between resin material, and described kneading operation is between fluffy and infiltration operate.
Forming step, synthetic resin is put into mould and heats extrusion forming, following steps are carried out: molding process in forming process, add the moulding material for strengthening synthetic resin performance in a mold, moulding material can be roving, have and twist with the fingers rove, continuous glass fibre bundle, glass fabric and glass mat etc., also there are a small amount of extraordinary goods to select asbestic blanket, abestrine cloth and asbestos paper and high silica fiber, carbon fiber, organic fiber and natural fiber etc., two or more fibrous material also can be adopted to mix; Strengthen step, add the auxiliary material strengthening synthetic resin performance further in a mold, auxiliary material comprise curing agent, promoter, diluent and surface conditioning agent, also include low shrinkage additive, releasing agent, colouring agent and filler etc.
Mirror process step, is provided with coating for diverging LED light source not having the uniform groove groove surfaces arranging several dome shape of completely crued lens inner face.Each groove shapes is identical, and two adjacent grooves to intersect and intersect that area is greater than that arbitrary groove is projected in inner lens surfaces area 1/2 along inner lens surfaces.
Above embodiment is only not limited in order to technical scheme of the present invention to be described, all do not depart from spirit and scope of the invention any amendment or equivalently to replace, it all should be encompassed in the scope of technical solution of the present invention.
