The specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of is the scald apparatus of light source with the arc light, comprise a camera bellows 7 that has light hole 10, in camera bellows by on the optical axis at light hole center from as far as being provided with arc light 2 closely successively, convex lens 3, concavees lens 4, sheet glass 5, every tabula rasa 5, arc light is arranged on the focus of a parabolic concave mirror 1, the light that arc light sends is by the reflection of parabolic concave mirror 1, become directional light, from convex lens 3 one side incidents, and converge in the focal point F place of its opposite side, the concavees lens 4 of this light that converges through being arranged on focal point F or the focal point F outside become parallel scorching hot hot spot, hot spot passes through sheet glass, by the aperture of crossing optical axis on tabula rasa, cast out at last through camera bellows light hole 10; Concavees lens 4 are adjustable in focal point F position to one section optical axis of the some 2F of 2 times of focal lengths of convex lens; Between the aperture of tabula rasa 6 outside and camera bellows light hole 10, be provided with the optical switch device 8 of connection timer 12; Be provided with the temperature probe 9 that connects temperature indicator 11 every the aperture inboard of tabula rasa.Concavees lens 4 and between tabula rasa 6 sheet glass 5 exit temperature that can be used for regulating scorching hot hot spot.
As shown in Figure 2, optical switch device 8 comprises a T shape armature curtain sheet 13 that is arranged between the aperture of the tabula rasa outside and camera bellows light hole, its top is provided with an electric magnet 14 and connects described timer 12, control the break-make of electromagnet coil current by function timer, and then adhesive or disengagement T shape armature curtain sheet 13, realize the outgoing of the scorching hot hot spot of control.On the aperture of tabula rasa 6, can be provided with the aperture that changes hole diameter.
The present invention can be provided with the self-clocking system in timer, connect the closed electromagnetic electromagnet coil by chronotron and decide light application time, promptly begins automatic countdown from high light contact animal skin, and countdown finishes to cover light source automatically, makes the scald time more accurate.
Because this instrument adopts the source of ultraviolet arc light as heat energy, prevent the influence that extraneous light is used up experiment in the camera bellows 7 so light source is placed on.Arc light 2 can obtain stabling current with manostat, thereby makes electric energy stably be converted to luminous energy.
Operation principle of the present invention is will compile the light that comes from parabolic concave mirror 1 with convex lens 3 converge to focal point F once again, temperature control system just in this focal point F to one section optical axis of the some 2F of 2 times of focal lengths of convex lens.At F-2F, change the height of controlling the emergent light temperature by concavees lens bright dipping facula area size by the distance on optical axis that changes concavees lens 4, can accurately obtain the temperature data of emergent light by temperature probe 9 and temperature indicator 11.Usually, the temperature of emergent light should be controlled at the 80-100 degree; By the aperture on the tabula rasa aperture, regulate hole diameter again.Change the size of the cross-sectional area of outgoing beam, to reach scalding area to requirement of experiment.
For can more accurate control temperature, the special sheet glass 5 that is provided with at concavees lens 4 and on the optical axis between the tabula rasa 6, by changing the fine adjustments that sheet glass and the angle of perpendicular decide temperature (two extreme positions: the vertical light maximum that hinders, parallel with optical axis, hinder the light minimum) with optical axis.
The present invention adopts automatic timing unit in light application time control, the T shape armature curtain sheet 13 of closing the light-emitting window place automatically when arriving Preset Time, and illumination stops thereupon immediately, therefore can reach the accurate control to the time.This instrument self-clocking system and light source can adopt parallel circuit, when timing finishes outage, do not cut off circuit of light sources, guaranteed the continous-stable of light source, only need open T shape armature curtain sheet 13 when reusing once more and can self-clocking repeat above process, help accurately molding in batches.
