Description
Technical field
The utility model relates to field of illuminating lamps, relates in particular to a kind of led light source.
Background technology
Energy shortage is the hot issue of the world today, and in illuminating industry, led light source is because multiple advantages such as its efficient, energy-saving and environmental protection, long-lives, is that to replace energy consumption high, the first-selection of the traditional lighting that the life-span is short.Existing LED is by substrate, formations such as wafer, insulating cement, gold thread, fluorescent material, and wherein the wafer of led light source all is to be encapsulated on nontransparent substrate, the most frequently used nontransparent substrate is exactly an aluminium base.The defective of existing product is that Chip Packaging is blocked by nontransparent substrate in the last beam split of nontransparent substrate, and the emission angle maximum of light also has only 180 degree, and the utilance of light is low, and the single and structure production cost that adopted aluminium base of structure is also than higher.
Summary of the invention
The purpose of the utility model is the low problem of utilance for the light that overcomes existing led light source existence, provides a kind of utilance of light high, novel structure, the led light source that production cost is low.
In order to realize the foregoing invention purpose, the technical scheme below the utility model has adopted:
A kind of led light source comprises chip, fluorescent material and flexible PCB plate, and fluorescent material is coated on the chip, and chip is fixed on the flexible PCB plate, and the flexible PCB plate is transparent or semitransparent shape.
As preferably, said flexible PCB plate is polyimides or the mylar substrate that is printed with circuit, and production cost is low, and heatproof is effective, and the especially long-time back flexible PCB plate that uses can the luminous efficient of turning black and changing color influence yet.
As preferably, said chip is through a kind of being bonded on the flexible PCB plate in insulating cement, elargol or the tin cream, and chip electrode connects the circuit on the flexible PCB plate through gold thread, and the service time that is connected firmly is long.Said insulating cement is epoxy resin or silica gel.
As preferably, be welded with lead on the said flexible PCB plate, lead is connected on through soldering on the circuit of flexible PCB plate and at weld and covers adhesive securement.Lead can connect power supply, and above-mentioned lead fixed is very firm, long service life.
As preferably, the bending of said flexible PCB plate is curved and can not knuckle, and bending is curved is convenient to process different shape, improves luminous efficiency, behind the knuckle flexible PCB and on chip fracture damage easily just, can not use.
As preferably, the top and bottom of said chip or scribble fluorescent material all around respectively, the color that fluorescent material is regulated the light that chip sends realizes that all luminous i.e. 360 degree of chip are luminous.
As preferably, rule is provided with the polylith chip on the said every flexible PCB, and luminous efficiency is higher.
A kind of led light source by the technique scheme design; Substrate on the led light source is the flexible PCB plate of transparent or semitransparent shape; Chip 360 degree is luminous all can to pass the flexible PCB plate, light transmission and can not being blocked arbitrarily, and the utilance of light is more than doubled; And do not re-use structures such as traditional aluminum base plate or support, production cost reduces greatly.The advantage of this led light source is a novel structure, and the utilance of light is high, and production cost is low.
