Abstract
The utility model relates to an LED lamp, particularly to a large power UV LED lamp with a cooling structure. The lamp comprises a substrate and a plurality of UV LED chips. The plurality of UV LED chips are uniformly fixed to the positive surface of the substrate. The lamp is characterized in that the back surface of the substrate is covered by a cover plate. An enclosed cooling liquid chamber is disposed between the cover plate and the back surface of the substrate. The cover plate is provided with an inlet pipe joint and an outlet pipe joint that are communicated with the cooling liquid chamber. The inlet pipe joint, the cooling liquid chamber and the outlet pipe joint form a cooling medium flow channel. Since the cooling medium flow channel is disposed between the substrate and the cover plate, the medium can be fed from the inlet pipe joint and discharged from the outlet pipe joint. The cooling medium is fed into the cooling medium flow channel in a cyclic manner to carry out forced cooling for the large power UV LED lamp. Since the cooling medium flow channel is directly disposed at the back surface of the substrate, conditions that an external cooling device leads to low cooling efficiency due to poor contact are prevented, and better cooling effects are achieved.
