Specific embodiments:
Referring to Fig. 1,2,3,4,5, the described stereo microscope LED cold light source of present embodiment illuminator, comprise microscope body 1, last light source, following light source, power supply 13, power change-over switch 11 etc., wherein, last light source is made up of the last light source PCB circuit board 20 of interior carriage 3, external fixation carriage 4, last light source light emitting diode (LED) 5, annular, last light source light emitting diode 5 is fixed on the PCB circuit board 20 of annular, and be fixed on outside the object lens 2 by external fixation carriage 4 and interior carriage 3, can move up and down with object lens 2.Described light source down is made up of following light source PCB circuit board 9 and following light source luminescent diode 8, and this time light source is mounted on the frosted glass below that object is placed in microscope body 1 bottom.
Last light source light emitting diode 5 described in the present embodiment adopts 32 Φ 5 super brightness (13000mcd), and long-life (100,000 hours) white light-emitting diode is formed, and is spacedly distributed, and forms circular being fixed on the annular last light source PCB circuit board 20.Have the fixing card 19 of a connection terminal on the interior carriage 3 of annular plastics of band " recessed " type mouth, be used to connect lead, the bottom of carriage 3 has 32 " eight " type holes 17 in being somebody's turn to do simultaneously.During installation, the PCB circuit board 20 that is welded with the annular of light source light emitting diode 5 embeds in the above-mentioned interior carriage 3, light source light emitting diode 5 is aimed at one by one with " eight " type hole 17 of falling of interior carriage 3 bottoms on each, firmly push PCB circuit board 20 and can make the pin natural torsion of light source light emitting diode 5 on each and surface level form 68 ° angle, make that light source light emitting diode 5 emits beam on each just in time can evenly focus on the target.The angle of last light source LED5 and plastic pallet can be 68 °, also can be not equal to 0 ° at least greater than 68 °, or, be not more than 90 ° at least, when object lens 2 move up and down less than 68 ° (deciding) on the LED visual angle, last light source is with object lens 2 one startings, and the maintenance hot spot focuses on the object all the time.
For gaining in strength, be provided with four reinforcements 18 in the carriage 3 in present embodiment is described.
Described light source luminescent diode down 8 adopts 18 Φ 5 super brightness (13000mcd), long-life (100,000 hours) white light-emitting diode is formed, array is fixed on down on the light source PCB circuit board 9, light shines directly on the object above it, because the observed object of its distance is nearer, the angle of divergence of following light source luminescent diode 8 is bigger than last light source light emitting diode 5.
Referring to accompanying drawing 6, the circuit side connector case of the described stereo microscope LED cold light source of present embodiment illuminator is: go up 32 LED5 in the light source, and parallel with one another again behind per two polyphones.18 LED8 in the following light source, in parallel again behind the polyphone equally in twos.
In order to reduce volume, power supply 13 adopts the AC-DC power supply power supply (also available transformer rectification circuit power supply) of 4-5W in the present embodiment.Adjustable continuously, stable, reliable in the requirement output voltage 5-9V scope, output current is not less than maximum current (500mA) when light source is worked simultaneously up and down, and high-low pressure will be isolated.
The LED light emitting diode is selected illuminating long-life (light decay reduces), the white pipe of super brightness (light intensity is not less than 12000mcd), and its half-power angle should be not less than 14 degree, but also should be too not big, otherwise luminous energy is not concentrated.
The resistance of contacting among the every couple of LED plays the dividing potential drop effect, causes each LED brightness irregularities to prevent LED parameter dispersiveness, so the parameter of the selection of its resistance and LED and electric power output voltage etc. are directly related, should calculate as follows:
Wherein: V is the voltage that is added in upper and lower light source two ends: V
LEDBe the terminal voltage of LED when 20 milliamperes of electric currents.The desirable summary of R is bigger than calculated value during actual value.
Last light source and following light source can be installed and used simultaneously also can distinguish to install separately as lighting source in a stereomicroscope and use.Can switch on simultaneously when installing and using simultaneously in stereomicroscope work and light modulation also can be distinguished separately by work and light modulation.Can also can power respectively with 13 power supplies of a power supply for the scope of application of enhanced system, can connect alternating current by plug 15 and give power supply 13 powered operation, also can directly connect DC power supply without power supply 13 and plug 15 with different electrical power.For be more convenient for working service and change LED lamp battle array of total system, light source can connect by two PIN up and down, also can directly dock.The utility model is that therefore exploitation the utlity model has good market outlook and social benefit to the new application of existing stereomicroscope cold light source illumination.
