Abstract
A kind of flexible COB light source of the utility model, comprise two-sided flexible circuit board 1, LED flip chip 2, fluorescent material, glue 3, it is characterized in that: the front of two-sided flexible circuit board 1 is provided with can the circuit of conducting electrical signals, distribute LED flip chip 2 on the circuit card 1, and LED chip 2 is provided with fluorescent material, glue 3 above, and corresponding LED flip chip 2 position, circuit board 1 back side is provided with copper sheet.
Description
Technical field
The utility model relates to field of LED illumination, specifically refers to a kind of flexible COB light source.
Background technology
COB be English CHIP ON BOARD(chip onboard) abbreviation, COB light source is by multiple blue-light LED chip encapsulation on circuit boards, white light is sent, the different-colour white light regulating the proportioning of fluorescent material and glue to obtain people to want through fluorescent material, glue.COB light source because have photochromic soft, heat conduction evenly, easily the advantage such as luminous intensity distribution be widely used in LED illumination industry in recent years, along with the extensive use of COB light source product in every field, market requires just to present to COB light source product diversity.
COB light source has application aluminium base, ceramic substrate, specular aluminium, several form of copper base on the market at present, the substrate of this several COB light source application is all hard, can not bend, and the application LED chip of this several light source is the packaged type of traditional die bond bonding wire, even if substrate can bend, also present COB light source on the market can have influence on the bonding wire of chip, easily damage product, so all can not meet some application products to the flexible requirement of COB light source.
Summary of the invention
The purpose of this utility model is to solve some application products to the flexible requirement of COB light source, and provides a kind of flexible COB light source.
A kind of flexible COB light source, comprise two-sided flexible circuit board, LED flip chip, fluorescent material, glue, it is characterized in that: the front of two-sided flexible circuit board is provided with can the circuit of conducting electrical signals, distribute LED flip chip on circuit boards, is provided with fluorescent material, glue above LED chip, and the corresponding LED flip chip position of back of circuit board is provided with copper sheet.Application flexible circuit board realizes the flexible Functional Requirement of COB light source, application LED flip chip is without the need to bonding wire, directly be mounted on the front of circuit board, avoid the requirement that traditional die needs bonding wire, damaged when preventing COB light source from bending, two kinds of application combine, and efficiently solve some application products to the flexible requirement of COB light source.For making this product more solid and reliable, applying two-sided flexible circuit board, being provided with copper sheet in the position of the corresponding LED chip of back of circuit board, playing the effect of protect IC.
The beneficial effects of the utility model are: can realize 360 degree luminous, and can to bend as required, as circle, square, triangle or other arbitrary shapes can be bent to.
Accompanying drawing explanation
Fig. 1 is side cut away view of the present utility model.
Fig. 2 is the partial enlarged drawing of the utility model side cut away view.
Embodiment
For making the purpose of this utility model, technical scheme and advantage more clear, below in conjunction with drawings and Examples, the utility model is described in further detail.Be to be understood that specific embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
With reference to shown in accompanying drawing 1 to 2, a kind of flexible COB light source of the utility model, comprise two-sided flexible circuit board 1, LED flip chip 2, fluorescent material, glue 3, is characterized in that: the front of two-sided flexible circuit board 1 is provided with can the circuit of conducting electrical signals, and distribute LED flip chip 2 on the circuit card 1, LED chip 2 is provided with fluorescent material, glue 3 above, and corresponding LED flip chip 2 position, circuit board 1 back side is provided with copper sheet.
The foregoing is only a kind of execution mode of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
