Disa ble Digital Signature Enforcement for 64bit WIN 7 8 10 If the driver need be installed in 64 bit Windows System, it need have digital signature. While some driver don’t have digital signature and the PC can’t install this kinds of device. If you want to install this device in 64 bit Windows System, You need disable digital signature enforcement. Our some equipment need disable signature enforcement, such as LMS-6000, LMS-7000 and LMS-9000 series spectroradiometer. For the 64 bit WIN7, We have a small program in the CD, like the picture below. We can disable digital signature by the CD. The program named as below. Double click it. 3.  Then click ‘Next’ 4. Click ’Enable Test Mode’ and go ‘Next’ 5.  Restart your PC 6. For the 64 bit WIN8 & WIN10. We can disable the digital signature on the PC directly. First hold down ‘Shift’ key and then click ‘Restart’ as below picture. 7.  Enter ...

Why should choose a constant current power supply for the LED driver? The LED is a light-emitting diode, and its characteristic curve is basically the same as that of a normal diode. When the applied voltage reaches the diode conduction voltage, the slight change of the applied voltage can cause a great change in the diode current. The constant current is used to ensure that the current in the LED is constant. No matter how the voltage changes, the current flowing through the LED does not change, which can ensure the life and light decay of the LED. If a constant voltage source with an output of 12V is used, an electric 16 ohm resistor is connected in series to supply three strings of 0.5W 5630 lamp beads. The lamp voltage is calculated according to 3.3V, the current flowing through the lamp bead Io=(12-3*3.3)/16=0.131A, and the power of a single lamp bead is P=0.131*3.3=0.4323W. Because the temperature of the lamp bead is high The voltage of a single lamp drops to 3V. At this time, th...
