The invention provides a vertical flip chip type light-emitting element which comprises a bare chip group, two first connecting pads, two second connecting pads and an electric connecting layer. The die set includes two dies and a first type semiconductor connection portion. The first type semiconductor connection portion is connected between the first type semiconductor layers of the two dies. A first one of the two first pads is disposed below a first one of the two dies, and a second one of the two first pads corresponds to but does not directly contact a second one of the two dies. A first one of the two second pads is disposed over a first one of the two dies, and a second one of the two second pads is disposed over a second one of the two dies. The electric connection layer is electrically connected with the second one of the two second connection pads and the first connection pad. Therefore, when a bare crystal is damaged, current can still flow into a normal bare crystal, so that a self-compensation function is realized.

The utility model relates to a high reliability leakproof fire hydrant especially to the technical field of fire engineering equipment, including main valve body, valve rod subassembly, drainage channel, the valve rod subassembly is provided with the same coaxial hard alloy sealing ring and self compensation sealing bush, and both form the stepped sealing interface, the utility model discloses set up hard alloy sealing ring, self compensation sealing bush, magnetic drainage valve element, memory alloy spring etc. part, through the stepped cooperation between hard alloy sealing ring and self compensation sealing bush, make sealing bush can through water absorption expansion automatic compensation sealing gap, combine the permanent magnet closing force of magnetic drainage valve element and the low temperature response characteristic of memory alloy spring, and magnetic drainage valve element can open drainage under the spring action when -5 DEG C ~ 0 DEG C. Further reached this device can through dynamic sealing compensation and low temperature automatic drainage, the effect that high pressure water flow sealing and valve body anti -freezing carry out double protection.
