Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
A kind of LED classroom lamp of the invention as shown in Figures 1 to 4, including lamp door 1, be installed on 1 inside of lamp door and successively fold
If impermeable tabula rasa 2, light guide plate 3, light diffusing sheet 4 and prism plate 5, the side of light guide plate 3, which is equipped with, to shine towards light guide tabula rasa 3
LED light source 6, the upper surface or lower surface of light diffusing sheet 4 or the upper surface of prism plate 5 are equipped with the giddy light by dominated layer of a shading, dizzy
Optical control layer is laid with several hollow out apertures.It is equipped with the LED light source 6 to shine towards light guide plate 3 by the side of light guide plate 3,
The upper surface or lower surface of light diffusing sheet 4 or the upper surface of prism plate 5 are equipped with a giddy light by dominated layer, and giddy light by dominated layer is laid with
Several hollow out apertures, the light for issuing LED light source 6 are issued with refraction from the hollow out aperture of giddy light by dominated layer by reflection, warp
It crosses prism plate 5 and is irradiated to the external world, keep the illumination of LED classroom lamp more uniform, reduce dazzle, anti-glare effect is more preferable, while LED
Classroom lamp by lamp door 1, successively fold set impermeable tabula rasa 2, light guide plate 3, light diffusing sheet 4, prism plate 5 and be set to 3 side of light guide plate
LED light source 6 form, compact overall structure and assemble simple, reduce the cost of manufacture of LED classroom lamp.
Giddy light by dominated layer is set to the upper surface of light diffusing sheet 4, and the upper surface of prism plate 5 is a smooth flat, prism plate 5
Lower surface be equipped with several array distributions graininess protrusion, be more advantageous to LED light source sending light by reflection with refraction from
The hollow out aperture of giddy light by dominated layer issues, and is diffracted into the external world by the graininess protrusion of prism plate 5, is further reduced dazzle, increases
Strong anti-glare effect.
Giddy light by dominated layer is ink for screen printing layer, and the manufacture craft of ink for screen printing layer is simpler, cost of manufacture is lower.Work as dazzle
When control layer is ink for screen printing layer, can silk-screen fibring sky circular hole is netted or square hole grid, the width and human eye of silk-screen look up into one
Fixed lamp shielding angle, to restrain dazzle, the width range of silk-screen are as follows: 1.2mm~2mm, formed 23mm*23mm or 18mm*18mm or
The uniform hollow grid of 13mm*13mm equal-specification.
Giddy light by dominated layer be film plating layer, film plating layer it is highly polished, reflecting effect is good, can reduce light scatter and disappear.
The color of giddy light by dominated layer is white, and white giddy light by dominated layer is smaller to the absorption of light, and the utilization rate of light is higher.
Hollow out aperture is circular aperture or square aperture, and circular aperture or square aperture can make the transmission of light more evenly.
Impermeable tabula rasa 2 is white reflection plate, and white reflection plate is smaller to the absorption of light, and the utilization rate of light is higher.
LED light source 6 includes strip aluminum substrate 7 and the LED lamp bead 8 being distributed on strip aluminum substrate 7, strip aluminium base
Plate 7 can reduce the production thickness of LED classroom lamp.
Front side portion, rear lateral portion, left side and the right side of lamp door 1 are equipped with radiating groove 9, conducive to LED light source 6 heat dissipation with
The arrangement of electric wire is installed.
The back of lamp door 1 is equipped with backboard 10, and backboard 10 is fixed on the concave station 11 at 1 back of lamp door by screw, makes backboard
10 installation is simpler.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
