Technical field

The utility model relates to LED technology field, and especially one exempts from driving LED integrated optical source.

Background technology

Integrated optical source and chipOnboard, that is: bare chip conduction or non-conductive adhesive are sticked on interconnect substrates, then carry out wire bonding and realize its electrical connection, being widely used on the various LED lamp products such as LED ball bubble, LED lamp cup, LED spotlight, LED down, LED Ceiling light, is one of main trend of current LED illumination light source.

But, when utilizing existing integrated optical source to carry out light fixture assembling, the driving power matched with integrated optical source must be configured, after carrying out AC-DC conversion, integrated optical source is powered; So, not only light fixture assembling process is loaded down with trivial details, fitting structure is too complicated, and improves the cost of lamp assembled.

Therefore, be necessary to propose improvement project to existing integrated optical source, improve the convenience that its assembling uses, and reduce the cost of lamp assembled.

Utility model content

For the deficiency that above-mentioned prior art exists, the purpose of this utility model be a kind of simple and compact for structure, without the need to configure independently driving power can carry out assemble use exempt from driving LED integrated optical source.

To achieve these goals, the utility model adopts following technical scheme:

One exempts from driving LED integrated optical source, it comprises substrate and array of source, the center of described substrate, be formed with box dam along the outer edge outline line of array of source, the surface of described substrate is provided with conductive circuit layer, described conductive circuit layer comprises the electrode line be connected with the positive pole of array of source and the negative line be connected with the negative pole of array of source, what described array of source was positioned at box dam encloses region, and described electrode line and negative line are all pressed between box dam and the surface of substrate;

It also comprises AC conversion chip and at least one integrated chip, and the end that positive pole output pin is welded in the end of electrode line, cathode output end is welded in negative line of described AC conversion chip, described integrated chip is welded in negative line.

Preferably, described substrate is made up of ceramic material, and the material of described conductive circuit layer is silver.

Preferably, it also comprises one for the shell of base plate for packaging, and described shell offers a socket, described array of source is flush-mounted in socket.

Preferably, the port edges of described socket is ramp structure, and the angle between the port edges of described socket and the axis of port is 45 °.

Owing to have employed such scheme, the utility model possesses the function of voltage transitions and driving light source array, when utilizing integrated optical source to carry out LED lamp assembling, without the need to independent configuration driven power supply, significantly reduces the production cost of light fixture; By utilizing coordinating between box dam with conductive circuit layer, not only can ensure the steadiness that array of source assembles, also can ensure that it has good electrical connection properties; It is simple and compact for structure, easy to assembly, has very strong practical value and market popularization value.
