While the lighting requirement of room, classroom background luminance is improved, student's visual adaptability is improved, avoids visual fatigue, is used conducive to student
Eye health, protects eyesight.
The utility model discloses a kind of light extracting LED lamps and lanterns up and down, is designed using Fresnel Lenses, not only diffusion angle it is big,
It shines wide, and effectively reduces quantity of light source, LED lamp bead arrangement more disperses, and conducive to heat dissipation, substantially reduces lamps and lanterns cost.
Traditional LED panel lamp, directly super bright using light source+diffuser, if quantity of light source is less, gap is larger between light source, lamps and lanterns
Surface easily forms dark space, largely effects on illuminating effect, by increasing quantity of light source, avoids the formation of dark space.With traditional panel
Lamp is compared, and the utility model discloses a kind of light extracting LED lamps and lanterns up and down, not only reduces the quantity of LED light source, reduce lamps and lanterns into
This, improves thermal diffusivity, and can be according to illuminating light distribution demand, flexible modulation light emitting angle, and applicability is good.
The utility model discloses a kind of light extracting LED lamps and lanterns up and down, small, at low cost using CSP lamp beads, is conducive to lamp
The superthin structure design of tool.
The utility model discloses a kind of light extracting LED lamps and lanterns up and down, and light extraction efficiency is high, at low cost, with traditional straight-down negative single side
Light extraction is compared, and is formed light extraction up and down, is effectively reduced dazzle, improves visual adaptability.With light extracting LED face above and below traditional side entering type
Plate lamp is compared, and cost is lower.
