In order to achieve the above object, a kind of affixed led circuit substrate of bridge plate of using that the utility model is designed, comprise fixing first substrate and second substrate of a plurality of led chips, it is characterized in that an end of crossing bridge plate welds first substrate, the other end welds second substrate, cloth is useful on the lead of electrical connection on the described bridge plate excessively, and described lead is communicated with the circuit on first substrate and second substrate.Passed through bridge plate after first substrate and the second substrate linear alignment and be connected, the connection that has not only realized circuit between substrate simultaneously but also guaranteed bonding strength between adjacent substrate to make the mutual mechanical fixation of adjacent substrate by crossing bridge plate.

Improve and replenish as the further of said structure, the utility model also comprises the combination in any of following additional technical feature or these features:

Described first substrate and the second substrate end are provided with the substrate solder joint, the described two ends of crossing bridge plate have locating notch, the above and below of described locating notch periphery and side all cover weld layer and locating notch shifts to install at substrate solder joint place, and scolding tin covers the lap-joint of locating notch and substrate solder joint.With this structure firm welding degree height.

Described first substrate and the affixed led chip of second substrate one side, another side is provided with the substrate solder joint, and mutual obstruction is avoided in the setting of staggering.

Attaching has function element on the described bridge plate excessively, and described function element is the function element with specific function, for example: rectifier, flow restricter, pressurizer, triode and resistance etc.

Described lead is a metal forming and between two locating notches, described lead is complex root and mutually disjoints.Number of conductors is decided according to the needs of substrate circuit.

The described bridge plate of crossing has polylith, crosses bridge plate quantity and decides as required, and welding flexibly.

Described locating notch was located at the bridge plate end, was square waveform, convenient welding, firm.

The described bridge plate of crossing is shaped as " ten " font, and described locating notch is rectangular in shape, and weld layer is arranged on the above and below and the side of square locating notch, and two leads connect corresponding weld layer, convenient welding respectively.

Described function element is a triode, plays the effect of current-sharing.

A kind of affixed led circuit substrate of bridge plate of using that the utility model obtains, guarantee the connection of circuit between substrate, and connect substrate to two and play the effect that interfixes, and firm welding intensity height, avoided effectively because the short circuit that reasons such as connecting line fracture, substrate displacement cause, and make attended operation simple, convenient, increase work efficiency.The long substrate that the short substrate of this usefulness connects into, the long substrate that cost is more directly produced Len req is low.
