| titleOfInvention | A kind of contactless great power LED method for testing junction temperature |
| abstract | The present invention relates to a kind of noncontact great power LED method for testing junction temperature, the method includes the steps of: A, LED junction voltage temperature variant temperature-sensitivity coefficient curve when obtaining small area analysis; B, for LED provides running current, after equalized temperature, measure LED junction voltage; C, running current is switched to small area analysis rapidly, utilize small area analysis junction temperature measurement method to measure now LED junction temperature; LED junction temperature when D, matching difference heat sink temperature and junction voltage, obtain the LED temperature-sensitivity coefficient under this electric current; The numerical value of E, change running current, repeats B ~ D, obtains the LED temperature-sensitivity coefficient under each working current; Under F, actual working state, record LED junction voltage, now LED junction temperature can be obtained according to the LED temperature-sensitivity coefficient under this working current.It is simpler that this method compares the operation of existing big current method for testing junction temperature, and measuring accuracy is higher, is easy to actual use. |
