130 include blue-ray light 132, optically focused part 134 and collimation lens 136.
Wherein, blue-ray light 132 is electrically connected with circuit controling assembly 120.Wherein, blue-ray light 132 sends blue light.Specifically,
The primary waves of the blue light that blue-ray light 132 sends is a length of 430 nanometers～490 nanometers.
Fig. 4 is seen also, in the illustrated embodiment, blue-ray light 132 includes LED/light source 1322 and substrate 1324, and
LED/light source 1322 is arranged on substrate 1324.Specifically, substrate 1324 is aluminium base.
Further, because the stimulation that long-time receives blue light can cause n and V and headache of people etc. to react, cause
Medical personnel are uncomfortable, and in order to improve the problem, in the present embodiment, LED/light source 1322 is multiple, and multiple LED/light sources 1322 set
Put on a surface of substrate 1324, the part in multiple LED/light sources 1322 is blue light source, another part is light modulation light
Source, wherein, dimmed light sources are white light source or yellow light sources.
Wherein, the quantity of blue light source and dimmed light sources can be arranged according to specific needs.For example, one embodiment wherein
In, blue-ray light 132 includes 2 dimmed light sources and 7 blue light sources；For example, 2 white light sources and 7 blue light sources；Or 2
Yellow light sources and 7 blue light sources.And 2 dimmed light sources and 7 blue light sources are arranged in a pros on substrate 1324
Shape.
It is appreciated that LED/light source 1322 can also all blue light sources.
Optically focused part 134 can change the dispersion angle of light.In the illustrated embodiment, optically focused part 134 is stub end and little
The housing that head end is open.Blue-ray light 132 is arranged at the opening of little head end of optically focused part 134.
Fig. 5 is seen also, collimation lens 136 can collimate the light projected from optically focused part 134, and collimation lens 136
It is movable so as to adjust the size of the irradiation hot spot 20 that blue-ray light 132 is formed on infanette 110.Wherein, collimation lens 136 can be with
For positive lens.Specifically in the illustrated embodiment, collimation lens 136 is arranged near the opening of the stub end of optically focused part 134, collimation
Line of the lens 136 along the opening center of the little head end and stub end of optically focused part 134 may move.Line AB in Fig. 4 is optically focused
The straight line that the connection at the little head end of part 134 and the opening center of stub end is located, the AB along the line of collimation lens 136 may move.
Further, irradiation hot spot 20 is ellipse.Because neonatal physical trait is that four limbs are short, head big and trunk
Long, the ratio of head and whole body is about 1:4；Wherein, full 28 weeks of gestational age but the neonate that was born less than 37 weeks be referred to as premature or
Premature infant, height is typically in 40cm～48.5cm；The neonate of gestational age birth in full 37 weeks～42 weeks is referred to as term infant, height one
As be 48.5cm～50.7cm.In blue-light treatment, in order that the body of baby can be arrived as far as possible by blue light illumination, general meeting
Baby is allowed to lie low on the bed surface 112 of infanette 110, now, the projection of the body of baby on the bed surface 112 of infanette 110
Shape be similar to ellipse.Therefore, oval irradiation hot spot 20 can more adapt to the figure of baby.
Specifically, the major semiaxis and semi-minor axis for defining irradiation hot spot 20 is respectively a and b, and a:B=1.0～1.5.According to
The figure feature of baby, and assume that the arm of baby and the angle of trunk are 45 °, baby is on the bed surface 112 of infanette 110
The oval major semiaxis and the ratio of semi-minor axis that projection is located is 1.0～1.5, therefore, limit a:B=1.0～1.5 can be more preferable
Ground adapts to the figure of baby.So, the area S=π × a × b of oval irradiation hot spot 20.
Further, the opening of the stub end of optically focused part 134 be rectangle, collimation lens 136 perpendicular to collimation lens
The section of 136 primary optical axis is circle.Wherein, the long side of the opening of the stub end of optically focused part 134 and the length point of minor face are defined
Wei not m and n, and m:N=1.0～1.5, so that irradiation hot spot 20 meets a:The ellipse of b=1.0～1.5.Expanded according to optics
Exhibition amount Etendue (Optical invariant)=π S [sin (θ/2)]2(wherein, θ is the dispersion angle of light) understands,
In the case that etendue is constant, the positive correspondence irradiation hot spot of light of the long edge position of the opening of the stub end of optically focused part 134
20 semi-minor axis b, the major semiaxis a of the positive correspondence irradiation hot spot 20 of the light at the minor face of the opening of the stub end of optically focused part 134.
And can be obtained by etendue conservation, m/n=[a × (H2+b2)]/[(b×(H2+a2)], wherein, H is the major part of optically focused part 134
Hold to the vertical range of the bed surface 112 of infanette 110, because the value of H is typically much deeper than a values and b values, then, (H2+b2)/
(H2+a2) ≈ 1, therefore m/n ≈ a/b, so as to obtain m:n≈a:B=1.0～1.5.Therefore, for obtaining the exposure light of infanette 110
Spot 20 less (i.e. the angle of the emergent ray of optically focused part 134 is less), must increase the long side of the opening of the stub end of optically focused part 134
Length, conversely, to cause the irradiation hot spot 20 larger (i.e. the angle of the emergent ray of optically focused part 134 is bigger) of infanette 110,
The length on the long side of the opening of the stub end of optically focused part 134 must be reduced.Specifically in the illustrated embodiment, optically focused part 134
The opening of little head end is square.
Further, in order that the bed surface 112 of infanette 110 adapts to the figure of baby, the bed surface of infanette 110 is defined
112 long side and minor face are respectively L1And L2, L1:L2=1.0～1.5.And the position at the center of irradiation hot spot 20 and bed surface 112
Center overlap.
Further, in order that the light that the opening of the stub end of optically focused part 134 is projected can be collimated as much as possible thoroughly
Mirror 136 is collimated, the center of the opening of the extended line of the primary optical axis of collimation lens 136 and the little head end and stub end of optically focused part 134
Line coincident, and the maximum cross-section of the primary optical axis perpendicular to collimation lens 136 of collimation lens 136 with diameter greater than optically focused part
The length on the long side of the opening of 134 stub end.I.e. in the diagram, the extended line of the primary optical axis of collimation lens 136 and line AB weights
Close.

Position coordinates to the maximum ordinate of value, is calculated the major semiaxis a' and semi-minor axis b' for meeting the elliptic equation；
The circuit controling assembly is according to a:B=1.0～1.5, the a' and the b', are calculated respectively described a' pair
The b for the answering and corresponding a of the b'；And
The corresponding b and b' of the circuit controling assembly a', if the corresponding b of the a' are more than the b', institute
Irradiation hot spot is stated with the a' as major semiaxis, with the corresponding b of the a' as semi-minor axis, if the corresponding b of the a' are less than the b',
Then the irradiation hot spot is with the corresponding a of the b' as major semiaxis, with the b' as semi-minor axis；Or the circuit controling assembly ratio
The corresponding a and a' of the b', if the corresponding a of the b' are more than the a', the irradiation hot spot is with b' correspondences
A be major semiaxis, with the b' as semi-minor axis, if the corresponding a of the b' be less than the a', the irradiation hot spot is with the a'
For major semiaxis, with the corresponding b of the a' as semi-minor axis.
