| 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.
however, if the constant pressure circuit, and then applied orthe use of led modules in the constant current circuit,led neon sign but also to achieve the purpose of the led stability, this time, constant voltage circuit and re-applied or the use of led modules should be integrated in the constant current circuit together asa led control device. that the output from the control device to see inside, with a very low output resistance. because the led signs has a prominent "negative resistance temperature characteristics", that is, when the led work, along with junction junction temperature increases. |
