Abstract
The utility model relates to a source device of electronic flash lamp for colour printers, belonging to the field of photography. The source device of electronic flash lamp for colour printers is characterized in that the source device of electronic flash lamp for colour printers comprises a rectifying diode D and a capacitor C < 1 >; the two ends of the capacitor C < 1 > are connected in parallel with three identical flash lamp tube circuits; a flash lamp tube is respectively sheathed with an R-red glass tube, a G-green glass tube and a B-blue glass tube; each flash lamp tube circuit comprises an R, C series connection part, a glow starting coil, the flash lamp tube, a switch, etc. The utility model can design the size of a color printer as the size of a copier. The source device of electronic flash lamp for colour printers has the advantages of low cost and less power consumption. The utility model can be widely used for factories and mines, armies, government offices, schools, or individuals.
Description
A kind of colour enlarger electronics flash light source apparatus.Described X-flash light supply apparatus is used in the colour enlarger, belongs to the camera work field.
Present domestic and international existing colour enlarger, its Lights section all selects for use the very big Halogen lamp LED of power to do light source.In use produce very high temperature and need otherwise processed, and require high stability of light source.Past, people controlled ac input end by stabilized voltage supply, and adopt the constant voltage of Switching Power Supply with the assurance bulb now the genus more, thereby kept the luminous and colour temperature of bulb stable.But the deficiency of these prior arts is: because increased many mechanical, electrical devices, cause volume to become big, power consumption increase, and increased the complete machine cost greatly.
The purpose of this utility model is to provide a kind of colour enlarger with electronics flash light source apparatus, and the film processor volume is big to solve, big energy-consuming, deficiency that cost is high.
Described colour enlarger is that with electronics flash light source apparatus principal feature it comprises commutation diode D and capacitor C
1, in described capacitor C
1Two ends three identical flash lamp tube circuit in parallel, be set with outside three flash lamp tubes that R-is red, G-is green, B-blue tinted glass pipe.
Described flash lamp tube circuit comprises R, C series connection part, common point at R, C connects the elementary end of starter coil T, after being connected, the secondary end of the elementary other end of described coil and coil connects gauge tap, described gauge tap is respectively: R switch, G switch, B switch promptly are red switch, green switch, blue switch.
Accompanying drawing has provided schematic diagram of the present utility model.As shown in FIG., power supply process diode is to capacitor C
1Charging, the elementary end of starter coil connects R
1, C
2Common port, and the starter end of a secondary termination flash lamp tube of starter coil.The starter coil is a step-up transformer, when switch (as the R switch etc.) when connecting, because C
1Discharge produces noble potential through the starter end at flash lamp tube L after the starter coil, thereby causes the flash lamp tube flash of light.
It is very little that the utility model can design colour enlarger; and it is luminous extremely strong; power is very little; color temperature constant; dynamo-electric part is extremely simple, for example can remove heat-protecting glass, exhaust fan etc., and it is similar with duplicating machine that complete machine can be done; and cost greatly reduces suitable factories and miness, army, office, school or personal.
