The light that the LED chip sent is seen through from first silica gel portion, because the silica gel of diffusant is added to first silica gel portion, the mixed light technique of having done of the colloid of the portion of appearing light (first silica gel portion) is handled for whole finished product luminous effect is very even, under the condition of certain density lamp pearl, can't see the light spot, and light is also very soft, and is not dazzling, reaches the COB lamp strip effect of the not visible light lamp completely.

Further, the LED chip is a CSP LED or a conventional LED. The CSP LED or the conventional LED or the like itself is subjected to the light splitting process.

Furthermore, the edge of the upper part of the second silica gel part is arc-shaped. The cross section of the PCB is square. Second silica gel portion upper portion edge adopts the arc transition for the whole outward appearance of novel COB soft lamp strip is more smooth, and the cross-section of PCB board is conventional for square.

Compared with the prior art, the beneficial effects are: the utility model discloses solve the discrete many BIN's of conventional COB lamp strip colour temperature problem completely. The problem that conventional COB lamp strip colour is miscellaneous is solved completely. The problem of conventional COB lamp strip waterproof not dustproof is solved completely, the performance of product has been improved, the production efficiency of product has been improved.

Additionally, the utility model discloses a product thickness can be done very thin, and the size can be done very little, can also work as the finished product and use, replaces current hard striation, can accomplish the field that some hard striations can not be done even, practices thrift system cost, and the application is very extensive, accords with market trend and demand, has very much market value.
