The light source of LED light fixture

Technical field

The present invention relates to field of illuminating lamps, relate in particular to a kind of light source of LED light fixture.

Background technology

The production of current LED light fixture mainly is to be divided into three big steps, at first is that the chip factory produces led chip, is that encapsulation factory is packaged into LED lamp pearl with led chip afterwards; Be only lamps & lanterns factory at last LED lamp pearl and other peripheral accessory are assembled into whole lamp, again because prior art is higher with the specification requirement that led chip is packaged into LED lamp pearl needs, so the equipment cost that needs is also very high; Several at least more than one hundred million necessarily at most, not most of lamps & lanterns factory can bear, so existing most lamps & lanterns factory directly buys LED lamp pearl to encapsulation factory; But because the LED lamp pearl of buying all is packaged, thus luminous intensity, parameter such as photochromic all can not change, and packaged LED lamp pearl because the series-parallel system of inner led chip fix; So drive unit is also fixed, can not flexible transformation, if the difference that the parameter of the LED lamp pearl that the client needs is sold with encapsulation factory; Then need custom-made, because the quality of the LED lamp pearl that encapsulation factory produces is to be directly proportional with the quantity of producing, cost then is to be inversely proportional to the quantity of producing again; This is because the equipment of encapsulation factory is to need the long debugging of process; If produce in a large number, then debug time generally can be very long and generally can not be gone to change its parameter again, makes that the product quality of producing is better; And because so the big cost of amount is also lower; If produce a small amount of, then debug time maybe be less and frequent the needs change parameter, the product quality of producing like this maybe be not high; And cost is also higher; Custom-made is if not mass customization thus, the cost of not only single led lamp pearl can be very high and also quality LED lamp pearl neither be very good, and the driving of LED lamp pearl also is a very big problem; So lamps & lanterns factory's customization small lot is not very worthwhile nor is very convenient; Also there are some lamps & lanterns factorys attempting oneself led chip being packaged into LED lamp pearl now, but because do not possessed good technology and dropped into not substantial contribution, so the LED lamp pearl uniformity of producing is not high and stable bad.

Summary of the invention

Technical problem to be solved by this invention is: provide that a kind of cost is low, the light source of quality better, high conformity and the LED light fixture that can meet the requirements of the customers flexibly.

The technical scheme that the present invention adopted is: a kind of light source of LED light fixture; It comprises a wiring board and a plurality of LED lamp pearl; Said a plurality of LED lamp pearl is pasted in the circuit board; And be electrically connected with wiring board, said a plurality of LED lamp pearls outside also covers the whole coating of one deck, and said each LED lamp pearl is packaged small size LED lamp pearl.

Adopt above structure compared with prior art; The present invention has the following advantages: if present lamps & lanterns factory uses the light source of this LED light fixture of the present invention; So just can not need go custom-made LED lamp pearl, only need to buy common packaged LED lamp pearl, select quantity and the series-parallel system of LED lamp pearl again according to client's demand flexibly; So not only be well positioned to meet client's demand, and select suitable drive mechanism more easily; And adopted the present invention; Lamps & lanterns factory is equivalent to carry out special customization; Like this encapsulation factory just only need certain several model of encapsulation LED lamp pearl just, no longer need often often to come the more parameter of exchange device according to client's demand, the LED lamp pearl quality of producing so also can uprise; Cost also can reduce; And because lamps & lanterns factory need not be packaged into LED lamp pearl with led chip, and just simply a plurality of LED lamp pearls are assembled in the circuit board neatly, so the light source uniformity height and the good stability of the LED light fixture of producing like this; And at a plurality of LED lamp pearls and the whole coating of wiring board outside covering one deck; The junction that so not only can prevent wiring board and a plurality of LED lamp pearls is exposed in the air; Play a very good protection, and whole clad material also can change, can select transparent material or trnaslucent materials to change luminous intensity; Can change direction of light through the concavo-convex degree that changes coating, can also be chosen in and add the colour temperature that fluorescent material changes light in the transparent material.

As preferably, said a plurality of LED lamp pearls are pasted and are meant in the circuit board, are bonded on the wiring board to said a plurality of LED lamp pearl marshallings.Neat arrangement in the circuit board, wiring board wiring is convenient like this, and the light effect that light source is broken forth is good.

As preferably, said packaged small size LED lamp pearl is meant through the single area of the encapsulation factory encapsulation LED lamp pearl less than 0.5 square centimeter.Select the LED lamp pearl of this area for use, can be not excessive even if use more LED lamp pearl to combine area yet, so the scope that luminous intensity can change is just bigger, give the scope of customer selecting just bigger, more can satisfy client's demand.
