Description
Technical field
The utility model is specifically related to a kind of multispectral led lighting detecting device, belongs to led illumination and detection technique neck
Domain.
Background technology
After lcd screen, oled screen have made layer of metal circuit processing procedure aborning, need to make layer of transparent guarantor thereon
Cuticula, because coating process improves, thickness does thinner and thinner, can accomplish 130nm at present, but, the uniformity of thickness can only
Ensure within +/- 20nm, as shown in Figure 1.Assume that 4% light can be reflected in the upper surface of transparent protective film, lower surface can reflect 4%
Light, metallic circuit processing procedure can reflect 25% light, be radiated on metallic circuit processing procedure with 450nm blueness led lighting source, thoroughly
Bright diaphragm is the region of 112.5nm thickness, and transparent protective film upper and lower surface reflected light interferes and balances out about 75%, always instead
Rate of penetrating is 27%, and transparent protective film is the region of 150nm thickness, and transparent protective film upper and lower surface reflected light is no interfered, total reflectivity
For 33%, the difference in two regions is up to 18%.
If from white led lighting source or red, green, blue mixed light led lighting source, this difference can reduce, according to
Red, green, blue, white, amber, green grass or young crops, the exemplary spectrum curve of ultraviolet led, white led is very high in the energy of wavelength 450nm, in ripple
The ability of long 480nm is very low, and red, green, blue led mixed light is very high in the energy of wavelength 450nm, 520nm, 630nm, in ripple
The energy of long 480nm, 580nm is very low, therefore, still can be obvious in some regions difference.
In addition, lcd screen, oled screen can make different circuit structures from different metals, different metal is to difference
The reflectivity of wavelength light can be different, and in general, wavelength is shorter, optical resolution higher it will usually from wavelength shorter
Light such as blue light improving optical resolution, but, in the circuit structure that measurement, detection such as copper metal make, because reflectivity
Relation green glow or white light can be selected sacrificial from longer wavelengths of light such as ruddiness improving picture contrast, most of the time
Some measurements of domestic animal, detection quality are improving measurement, detection efficiency.
The shortcoming of therefore prior art is that the Energy distribution in whole visible light is very uneven, and single wavelength selects
Less.
Content of the invention
For solving problem above, the utility model utilizes the characteristic of led, is combined whole visible ray from suitable led
Energy distribution spectrally is as uniform as possible, is exactly specifically the curve of spectrum of shorter wavelength and longer wavelength in 50% energy
Position intersects.
Specifically, the utility model provides a kind of multispectral led lighting detecting device, and described detection means is included in edge
The elements below of axle order arrangement: polychrome LED lamp (1), condenser lens (2), light uniforming device (3), secondary focusing lens (4),
Half-reflecting half mirror (5).
Further, multispectral led lighting detecting device as above, described polychrome LED lamp (1) is polychrome led lighting
Or polychrome led line lamp.
Further, multispectral led lighting detecting device as above, described polychrome LED lamp (1) is polychrome led lighting
For 460nm+480nm+500nm+520nm tetra- colored lights pearl.
Further, multispectral led lighting detecting device as above, described polychrome LED lamp (1) is polychrome led lighting
For white light+460nm+480nm+500nm four colored lights pearl.
Further, multispectral led lighting detecting device as above, described polychrome LED lamp (1) is polychrome led lighting
For 460nm+480nm+500nm+520nm+550nm+585nm+630nm seven-colour lamp pearl.
Further, multispectral led lighting detecting device as above, described light uniforming device (3) is optical tunnel or even tabula rasa.
It is seen that light Energy distribution spectrally is uniform, wavelength selects many, Neng Gouti to led detection means of the present utility model
High optical resolution, improves picture contrast, and improves measurement, detection efficiency further.
