Embodiment:

As shown in Figure 1, the described monochromatic light type of the utility model Dim Dimmer comprises photosensor 1, aerotron 2, relay 3 and electric capacity.Said photosensor 1 utilizes photosensor to convert optical signal the sensor of electric signal into, and its sensitive wave length comprises IR wavelength and ultraviolet wavelength near visible wavelength.Said aerotron 2 has the advantages that forward current conducting, counter-current end.Said diode 5 and the induction high pressure that relay 3 coils from parallel connection of coils clamp coils are produced play the effect of protective transistor.Said electric capacity 41 (C2) and 42 (C3) are parallelly connected with the normally-open normally-close contact of relay 3 respectively, and the spark that produces in the time of can eliminating the contact break-make plays the effect that prolongs the relay contact life-span.The little electric current of said relay 3 usefulness removes to control a kind of " automatic switch " of big electric current running, in circuit, plays effects such as automatically regulating, safety guard-safeguard, change-over circuit, has normally closed contact and open contact.Electromagnetic relay 3 generally is made up of iron core, coil, armature contact reed etc.As long as add certain voltage at the coil two ends; Will flow through certain electric current in the coil; Thereby generation galvanomagnetic effect, armature will overcome the pulling force of return spring under the effect of electromagnetic attracting force inhales to iron core, thereby drives the moving contact and break back contact (open contact) adhesive of armature.Behind coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return original position at the antagonistic force of spring, and moving contact (open contact) and original break back contact (normally closed contact) are discharged.Adhesive like this, release, thus reached the conducting in circuit, the purpose of cut-out.The light that the country beam that links to each other with the normally closed contact of said relay 3 sends is comparatively concentrated, and brightness is bigger, can shine far very high object.The passing light that links to each other with the open contact of said relay 3 is for closely illumination, and designing requirement is exactly range of exposures big (160 °), and irradiation distance has about 30～40 meters approximately.
