Description
[technical field]
The utility model relates generally to a kind of LED with PC diffuser.
[background technology]
Along with the raising of socioeconomic development and people's living standard, the requirement of people to commercial space is also more and more higher.Illumination is one of the important component part in space, shop, and Lighting Design can attract the sight with guide consumption person.By moulding of spatial light environment, mould spectacular spacial flex and show image, adopting multiple illumination gimmick to show shop theme image, allow people produce association, arouse the sympathetic response of consumer, setting up the emotion communication with consumer's intercommunication.
LED (Light Emitting Diode, light emitting diode) technology with its power saving, brightness is high, long service life, anti-seismic performance are good etc., and advantage is extensively promoted, the application of LED in normal lighting and display is in recent years more and more extensive.But the white light sent due to LED is with more blue light ingredient, and under the illumination of this light, the visual experience of people is not very natural, and the light ratio that LED lamp sends comparatively is dazzle the eyes, and easily causes dazzle.And LED is point-like illuminating source, its heat produced also concentrates on minimum region, if the heat produced cannot distribute in time, then directly can affect service life and the illumination effect of LED.In addition for light fixture, high printing opacity is little for light-emitting area and illuminator that light intensity is high, and often produce and dazzle the eyes even light pollution, conventional method reduces light intensity with the translucent cover of one deck.Improve the problem of dazzling the eyes, but also have lost the luminous flux of nearly 20% simultaneously.Light transmittance and anti-glare are conflict bodies, for the performance of diffuser, how to realize high transmission rate and anti-glare is a difficult problem all the time simultaneously, are difficult to take into account.The general light transmittance of LED is in the market low, illuminating effect is poor, does not possess thermolysis, and the product of the diffuser good transmittance simultaneously adopted is all expensive, and consumer is not easy the quality differentiating product, there is certain defect.
A kind of LED with acrylic light guide plate disclosed in China Patent No. (CN201320590817.X), comprise side active flat panel lighting module and straight-down negative plate lighting module, described side active flat panel lighting module comprise housing, the strip source be fixed in housing, for the acrylic light guide plate and being used for strip source being converted to planar light source, planar light to be carried out scattering, diffusion diffuser plate; The plane that described straight-down negative plate lighting module comprises shell, is fixed on the heat conduction backboard of shell and is fixed on backboard; Described straight-down negative plate lighting module is fixed on the active flat panel lighting module inside casing of side.This LED have employed acrylic light guide plate as transparent lamp shade, but acrylic production difficulty is large, cost is high, therefore market has the low inexpensive substitute of many matter.These substitutes are also referred to as " acrylic ", are common organic plates or composite plate (also known as filled board) in fact.Common organic plates adds pigment casting with common lucite cracking material and forms, and case hardness is low, fugitive color, poor with polishing effect after fine sand polishing.Composite plate only has very thin surface one deck acrylic, and centre is ABS plastic, and be affected by thermal expansion and contraction in using easy delamination.Ordinary consumer does not have experience to select, and causes often buying wrong product.
A kind of LED illumination module disclosed in China Patent No. (CN201280073902.7), comprising: frame, its underpart has pockets; Substrate, is fixed on the interior mounting surface of the pockets of frame, and has the multiple LED be arranged on above it; Multiple radiating fin, on the upper surface being arranged in frame and side surface, and separated from one another; And standing part, stretch out from the upper surface of frame, the bottom of standing part has the coupling aperture for be coupled substrate and bolt, but the multiple radiating fin of this module making needs more material for dispelling the heat, cause increasing of cost of manufacture, also increase manufacture difficulty simultaneously.
