Led that the number of led bai sent tens of milliseconds .ms constant current pulses simultaneously and instantaneous measurements of spectroscopic instruments to open the shutter, led emitted light on the parameters (flux, [link widoczny dla zalogowanych] light and color parameters, etc.) for rapid detection, but also synchronous acquisition led forward voltage drop and power and other parameters. because ofthis approach in the detection process, led junction temperature is almost equal to room temperature, so measurements of light efficiency, light color, and electrical parameters with significant differences in actual usage.
(3) packaging is the product of the last session before leaving the factory, packaging technology have a direct impact products to the hands of users is for qualified products. packagingshould be anti-static shielding bags, [link widoczny dla zalogowanych] it is used the device packaging, transport and storage, has a moisture-proof effect.
such led watch from the output control device in, [link widoczny dla zalogowanych] output impedance has a constant voltage output than the type of led control to high, but significantly lower than control led current output-type controls. such circuits can be connected led work-limiting impedance of the smaller led can work.
