Machine vision replaces human eye measure and judge with machine exactly.NI Vision Builder for Automated Inspection refers to that by machine vision product, will be ingested target converts picture signal to, sends special-purpose image processing system to, according to information such as pixel distribution and brightness, colors, is transformed into digitized signal; Picture system carries out to these signals the feature that various computings carry out extracting objects, and then control on-the-spot device action according to the result of differentiating, can measure for Mechanical Parts Size, the external form of electronic component, IC detects, film dust detection, transparent substance scratch detection, large-area circuits plate electronic device detects and identification, perspective dimensional measurement, the fields such as LCD bad point detection.
The iphone of Apple battery of mobile phone appearance and size detects; we find that the locus in battery production streamline is very narrow; can only adopt the method for optical projection; one light-emitting area 100 * 100mm is installed below battery of mobile phone; thickness is the Ultrathin LED flat light source of 8mm; utilize battery of mobile phone external form to block the principle of light-emitting area, just really appearance and size is reflected in industrial camera very easily in non-stop-machine situation by defective work go-on-go out.The successful research and development of this light source, have made up the domestic ultra-thin LED light source blank in manufacturing, and for the ultra-thin light source localization of LED, walk out Yi Tiaoxin road, have dwindled and external LED light source is manufactured the distance between advanced country simultaneously.Adopt unique leaded light mode, planar structure light source, has the little thin thickness of volume uniformly, and the life-span is grown again energy-conservation feature.The position of more difficult installation light source in the past, since this light source is born now can milli installation with no difficulty.
Utility model content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, a kind of thin thickness is provided, takies the LED super-thin plane light supply apparatus that volume is little, reflective evenly, luminous efficiency is high.
For realizing above-mentioned object, LED super-thin plane light supply apparatus of the present utility model by the following technical solutions:
This LED super-thin plane light supply apparatus, its main feature is, comprise LGP and diffuse reflector, this diffuse reflector is positioned at the top of described LGP, the surrounding of described LGP is all fixedly installed LED particle, shell is positioned at the below of described LGP, and described LGP is fixedly installed between described diffuse reflector and described shell.
The surrounding of the LGP in this LED super-thin plane light supply apparatus all has hemispherical shrinkage pool, and described LED particle is fixedly installed in this hemispherical shrinkage pool, and described LED particle is close to described hemispherical shrinkage pool.
Shell in this LED super-thin plane light supply apparatus is aluminum alloy casing.
Diffuse reflector fixed cap in this LED super-thin plane light supply apparatus is located at the top of described shell, and described LGP is located in described shell by this diffuse reflector fixed card.
