The Protection of Intellectual of LED Panel Light From:www.lgiled.com   Reporter:pamela   Date:2013/10/28 19:39:47   Tags:led-screen-module

To protect the led panel lights, our first thought is to use fuse, but the fuse is a one-off, and the reaction speed is too slow, the actual use of both poor and very troublesome, so not suitable for fuse LED lights are now finished because LED lights are now mainly in urban engineering and lighting engineering brilliance.

Beyond the normal use of current, it can immediately start protection, so that the LED power supply path is disconnected. The LED and power can be protected throughout the lamp automatically after normal power is restored, does not affect the LED work, it is critical because it civilian products, the increase of the circuit cannot be too complicated volume is not too large, the cost must be low. These requirements are contradictory, mutual restraint, it is very difficult to achieve.

Its size is small, and low cost, which can be used repeatedly to achieve the protection of the automatic start automatically exit; it is a solid impact-resistant packaging is not easy to be damaged; actual tests we found that; because it is heat-sensitive devices is affected by temperature great impact, because PTC encapsulated in the interior lamps, light bead sure to heat the PTC will affect performance. That have been identified through the test fixture can be selected PTC, more reliable way to use it farther away from the heat of the lamp beads.

At the front of each leg, we can plus a PTC element is individually protected. This approach has the advantage of high accuracy, reliability protection.
