Abstract
An LED injection-molded light guide plate comprises a circular plate base. The circular plate base comprises an incoming face, a reflecting face and an outgoing face. The surface of the outgoing face is provided with intensive raised dots which are 0.5-1mm in diameter and 0.03mm in raised height. The end of each raised dot is semispherical. The LED injection-molded light guide plate has the advantages that light guide efficiency of the light guide plate is improved greatly and production cost is saved.
Description
Technical field
The present invention relates to the LED light fixture and manufacture field, relate in particular to the LGP in the LED lamp.
Background technology
The LGP of current LED lamp on the market generally includes the plane of incidence, reflecting surface and exit facet thereof, but existing its plane of incidence of LGP on the market generally all is arranged at the plate body bottom surface, by in bottom surface, offering several, enter light source incident be used to the groove that LED is installed, its reflecting surface is arranged on the plate body wall, the major technique defect of its existence is that the groove quantity of plate body bottom surface arranges limited, and most critical be that incident light source is inhomogeneous, bright have dark that easily causes emergent light to have, have a strong impact on LGP leaded light efficiency, the technical staff addresses this problem by LED evenly is set on the wooden partition by plate body, make its wooden partition as the plane of incidence, using bottom surface as reflecting surface, surface efficiently solves the problems referred to above as exit facet, but the problem of thereupon bringing is that exit facet outgoing light source is inhomogeneous, reflecting surface can't effectively reflect or reflection efficiency low, the problems referred to above have much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of bright dipping even, and the high LED injection mo(u)lding LGP of reflection efficiency.
Key problem in technology of the present invention is, at the exit surface of LGP, intensive cloth luminous point is set, effectively carry out light source uniform, can softly emit uniformly, improve leaded light efficiency, main also being effectively arranged luminous point and its large low height carried out to the preferred of refinement, draws the highest leaded light efficiency.Its concrete technical scheme is: LED injection mo(u)lding LGP, comprise the circular plate type matrix, described matrix is comprised of the plane of incidence, reflecting surface and exit facet, it is characterized in that described exit facet surface is provided with intensive round point shape projection, described projection diameter is 0.5 ~ 1mm, described height of projection is 0.03mm, and described protruding end is hemispherical.
As preferably, be that described matrix thickness is 8 ~ 10mm.
As a further improvement on the present invention, described density of protrusions increases and becomes and dredge gradually with the distance of the distance plane of incidence.
As a further improvement on the present invention, described reflecting surface is provided with the vee-cut array.By this kind setting, can greatly improve reflection efficiency.
As preferably, described matrix is once injection moulding.By this kind setting, can greatly reduce cost of manufacture, improve production quantity.
Beneficial effect of the present invention: the present invention has improved the leaded light efficiency of LGP greatly, and saves cost of manufacture.
The accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is protruding schematic diagram.
The specific embodiment
LED injection mo(u)lding LGP, comprise circular plate type matrix 001, described matrix 001 is comprised of the plane of incidence 011, reflecting surface 012 and exit facet 013, described exit facet 013 surface is provided with intensive round point shape projection 131, described protruding 131 diameters are 0.5 ~ 1mm, described protruding 131 is highly 0.03mm, and described protruding 131 ends are hemispherical.Described matrix 001 thickness is 8 ~ 10mm.Described protruding 131 density increase and become and dredge gradually with the distance of the distance plane of incidence 011.Described reflecting surface 012 is provided with vee-cut 121 arrays.Described matrix 001 is once injection moulding.
