, then can only be by making the filament of different-colour respectively but LED filament product is to realize that different-colour is adjustable Light source, then combination are arranged in light fixture, it is such the shortcomings that when being illumination outward appearance have obvious color distortion, illumination effect Fruit is bad.Therefore the technology is necessary to be improved.

Utility model content

For overcome the deficiencies in the prior art, the utility model provide one kind realized on same LED filament light source to The encapsulation of few two or more different-colour chips, so as to realize the LED module of the adjustable color of a filament.

Technical scheme is used by the utility model solves its technical problem：

A kind of Dimmable LED module, including：The LED chip of at least two different-colours and/or color, each LED core Piece is arranged on substrate, and each LED chip is packaged as a whole；

The substrate is provided with circuit, is electrically connected to each LED chip with power supply.

As the improvement of the technical scheme, each LED chip is controlled using independent driving current.

As the improvement of the technical scheme, the material of the substrate is ceramics or glass or sapphire or metal or fiberboard Or polyimide flex material.

As the improvement of the technical scheme, each LED chip uses formal dress and/or flip-chip.

Further, the LED chip includes white chip and/or blue chip and/or red light chips and/or green glow core Piece.

Further, the LED chip includes the white chip of at least two different-colours.

Further, the encapsulation glue that the LED module uses includes silica gel or epoxy.

The beneficial effects of the utility model are：Dimmable LED module provided by the utility model, by by least two not The LED chip of homochromy temperature and/or color is packaged as a whole, and at least two can be realized on same LED filament light source by reaching The encapsulation of above different-colour, it is very convenient so as to realize the effect of the adjustable color of a real filament, and structure Design is simple.

Embodiment

Design, concrete structure and caused technique effect of the present utility model are carried out below with reference to embodiment and accompanying drawing Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment It is part of the embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area The other embodiment that art personnel are obtained on the premise of not paying creative work, belong to the model of the utility model protection Enclose.In addition, all connection/annexations being related in patent, not singly refer to component and directly connect, and refer to can be according to specific Performance, by adding or reducing couple auxiliary, to form more excellent draw bail.Each skill in the utility model creation Art feature, can be with combination of interactions on the premise of not conflicting conflict.

A kind of Dimmable LED module, including：The LED chip of at least two different-colours and/or color, each LED core Piece is packaged as a whole, and each LED chip is arranged on substrate；

The LED chip of at least two different-colour and/or color, it includes the same color of at least two different-colours Chip, such as the white chip of different-colour, in addition at least two chips (white+its allochromatic colour) of different colours or at least two Kind colour etc., to realize tunable optical.

As the improvement of the technical scheme, each chip is controlled using independent driving current.Using independent driving, Light modulation is realized, it is very convenient.

The tunable optical or the LED filament product of colour temperature that this programme provides, wherein chip array are arranged on substrate, chip Quantity is at least 2 kinds, and the color of the chip can be the colors such as blue light, feux rouges, green glow, or white light, according to wanting for design Ask, the chip of different colours is arranged on the relevant position of filament substrate, then unitary packed, and the module can be single Control the chip of each color.

Wherein chip surface is packaged with glue, and glue can be transparent adhesive tape or the fluorescent glue for being mixed with fluorescent material, so as to real Existing different colours are adjustable.Encapsulation glue can be silica gel or epoxy, according to product design be necessary to determine whether be mixed with fluorescence Powder, the encapsulation glue are at least coated in the one side of filament substrate, and the cross section for coating the product after packaging plastic can be oval Shape, it is round, it is square etc..
