Post subject: Some ideas to keep in mind when you have your Boar
Led led modules as possible to monitor the junction voltage, should be the preferred monitoring junction voltage. otherwise, theled module should be designated to monitor the temperature of the temperature measurement point. " results can be seen in monitoring the conditions of voltage down the optical parameters measured
writing board
module is to ensure reproducible detection of the preferred solution, but the standard did not specify the actual use of the junction temperature in the simulation test led module under the conditions of light, color, electrical parameters.
constant-current test open circuit voltage of the power can not be too high to prevent led pulse voltage by the impact of negative feedback and failure. (2) form to the human body with astatic situation in several states, from which is easy to see under the same conditions, humidity rise, reducing the electrostatic potential u,

which reduced the risk of esdlower, but stillexists, therefore, not relax static protection, to maintain good work habits.
such controls should also be marked led rated output voltage.and maximum output current.

control output voltage control devices the most obvious feature is its rated voltage, the output circuit at light load (for example, 20% to 30% load rate) and full load conditions, little change in the output voltage (output voltage change rate is generally not more than 30%), but if the rated output of each single string of one more loop led will not work.
