Guangzhou LED corn light film are few patches in series or parallel? Aluminum plate corn lamp, using resistance capacity step-down power supply, is six side board and film series connection (among them, each patch and the patch for parallel), and then distinguish is negative plugged into a power supply. Guangzhou LED corn light Q: a few patches on the film is in series or parallel? If you want to drive power supply with constant voltage source site is what kind of light source language is the patch? I saw some pictures like a straw hat lamp Answer: on the aluminum strips is single (three chip) parallel veneer (does a set series, if you can calculate with constant voltage source, a single straw hat and patch (single three core series) start voltage between 3.0 ~ 3.5 V, current don't more than 20 ma (control between 15 ~ 18 more appropriate), patch three column parallel current for 45 to 60 ma. Usually use serial method, access to the constant current power supply. Guangzhou LED corn light |
