Described transparency carrier is provided with the mould adhesive layer that contains some smooth granule proliferations, arranges LED chip array more and is all located in mould adhesive layer.The light of the different-colour that when so, the utility model is applied, many row's LED chip arrays send determines the light characteristic of filament after the mixed light of exterior light granule proliferation.

Further, the material of described transparency carrier is glass or crystalline ceramics.

The fluorescent material composition similarities and differences in the fluorescent material glue-line that in described many row's LED chip arrays, any two row's LED chip arrays arrange.

For the ease of management and setting, described transparency carrier forms rectangular shape, and the LED chip of arranging in LED chip array is all arranged along transparency carrier long axis direction more.

Further, the quantity of described LED chip array is two rows, and described transparency carrier length is 1～20cm, and transparency carrier width is 1～10mm, and transparency carrier thickness is 0.2～3mm.

Further, described transparency carrier length is 2～10cm, and transparency carrier width is 1.5～5mm, and transparency carrier thickness is 0.5～1.5mm.

Compared with prior art, the utlity model has following beneficial effect: (1) the utility model arranges many row's LED chip arrays on transparency carrier, every row's LED chip array comprises a plurality of LED chips, and each LED chip is provided with fluorescent material glue-line, many row's LED chip arrays are the fluorescent material composition similarities and differences of fluorescent material glue-line to each other, the utility model overall structure is simple, be convenient to manufacture and realize, when the utility model is applied, by carrying out size of current control to many rows LED chip array, can make this region launch the light of different-colour, so, during the utility model application, can realize tunable optical, easy to utilize.

(2) the utility model also comprises mould adhesive layer, and mould adhesive layer contains some smooth granule proliferations, and the utility model, in the situation that adopting transparency carrier, then by exporting after the effect of light granule proliferation, so, can be realized omnibearing luminous again while making utility model application.
