Abstract
The invention discloses a circular light emitting diode (LED) surface light source lamp. The circular LED surface light source lamp comprises a light guide plate, an LED lamp and reflective groove net points. The LED lamp is located on the lateral portion of the light guide plate, the reflective groove net points are distributed on the bottom surface of the light guide plate, and the reflective groove net points on the bottom surface of the light guide plate are distributed from dense to sparse and from the center to the edge. According to the circular LED surface light source lamp, the reflective groove net points on the bottom surface of the light guide plate are distributed from dense to sparse and from the center to the edge, so that the uniformity of output light is further improved.
Description
Technical field
The invention belongs to LED lamp field, particularly relate to a kind of round LED area source lamp.
Background technology
LED area light source has high, photochromic pure, low in energy consumption, the advantage such as the life-span is long, reliability and durability, five pollutions of efficiency, and be widely used in the numerous areas such as FPD, daily illumination, ad decoration and tunnel illumination, its market prospects are very wide.Side entering type conduit module is a kind of method of common acquisition area source, and in the art, light guide plate is the communication media of light source.At present, the preparation method of scattering netted dot pattern has printing-type and non-printing formula two kinds.Printing-type: after light guide plate completes sharp processing, is imprinted on reflecting surface with mode of printing by site, is divided into again IR and UV two kinds.Non-printing formula: by site when light guide plate is shaped direct forming at reflecting surface.Be divided into again chemical etching, precision optical machinery portray method, photolithography and diffusion inside.The uniformity of the current output light by side entering type conduit module acquisition area source need further raising.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of round LED area source lamp, achieves output optical uniformity high and energy-conservation.
Technical scheme: for achieving the above object, technical scheme of the present invention is as follows:
A kind of round LED area source lamp, comprises light guide plate, LED and reflective groove site.Described LED is positioned at the sidepiece of light guide plate, reflective groove network point distribution on the bottom surface of light guide plate, the reflective groove site on bottom surface of light guide plate from center to edge by close to thin distribution.
Further, the inner surface of described reflective groove site is coated with scattering layer
Further, the size of the reflective groove site on described bottom surface of light guide plate diminishes gradually from center to edge.
Further, the cross section of described light guide plate is circular.
Beneficial effect: the present invention by the reflective groove site on bottom surface of light guide plate from center to edge by close to thin distribution, achieve and export the uniformity of light and be further improved.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is reflective groove site of the present invention topological structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figures 1 and 2, a kind of round LED area source lamp, comprises light guide plate 1, LED 2 and reflective groove site 3; Described LED is positioned at the sidepiece of light guide plate 1, and reflective groove site 3 is distributed on the bottom surface of light guide plate 1, the reflective groove site 3 on light guide plate 1 bottom surface from center to edge by close to thin distribution, and the inner surface of reflective groove site 3 is coated with scattering layer.
The size of the reflective groove site 3 on light guide plate 1 bottom surface diminishes gradually from center to edge, and the cross section of described light guide plate 1 is circular.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
