Concrete meaning in this utility model.
Referring to figs. 1 through shown in Fig. 3, this utility model embodiment provides a kind of LED strand 1 carrying constant current chip,
Including substrate 11, constant current chip 14 and multiple LED chip 13.
Concrete, one end of substrate 11 is provided with positive pole pin 16, the other end is provided with negative pin 17.
Constant current chip 14 is arranged on substrate 11.
Multiple LED chip 13 are arranged on substrate 11 and are spaced along the length direction of substrate 11, and multiple LED chip are led to
Crossing tinsel 12 and be electrically connected to form LED chip string, one end of LED chip string electrically connects with positive pole pin 16, LED chip string another
One end electrically connects with one end of constant current chip 14, and the other end of constant current chip 14 electrically connects with negative pin 17, say, that LED
Chip string is connected in series with constant current chip 14, and the electric current flowing through each element in series circuit is the most equal, therefore flows through LED core
Sheet string is equal with the electric current flowing through constant current chip 14.Constant current chip 14, with crystal triode for mainly comprising device, utilizes crystal
Transistor collector change in voltage is little on electric current impact, and use Current Negative Three-Point Capacitance to improve the homeostasis of electric current, and LED chip
13 is nonlinear device, and the minor variations of forward voltage can cause the great changes of forward current, and this explanation LED chip 13 is easily
Being affected by curent change, therefore, the electric current controlling to flow through LED chip string by constant current chip 14 is constant current, so
It is to ensure that to flow through LED chip string the most equal with the electric current of constant current chip 14 and do not affected by input voltage and protect all the time
Holding constant, the light luminance that multiple LED chip 13 so can be made to send keeps stable.It practice, can also use another
A kind of connected mode: multiple LED chip are electrically connected to form LED chip string, one end of LED chip string and negative pole by tinsel 12
Pin 17 electrically connects, and the other end of LED chip string electrically connects with one end of constant current chip 14, the other end of constant current chip 14 with just
Pole pin 16 electrically connects, and such LED chip string is to be connected in series as constant current chip 14, flows through LED chip string and flows through perseverance
The electric current of stream chip 14 is the most equal.
Existing constant-current driving power supply, constant current chip 14 is arranged on, and therefore the electric current of constant-current driving power supply output is
Through being constant current, but usual this constant-current driving power supply volume can be bigger and price is higher, by this constant-current driving power supply
When being installed on whole lamp, being not easy to operation, the cost performance of whole lamp also ratio is relatively low.Compared with existing constant-current driving power supply, this
Just constant current chip 14 is arranged on LED strand, forms a kind of LED strand 1 carrying constant current chip, it is not necessary to use cost
High special constant-current drives power supply, only uses general driving power supply also can replace, the most greatly saves production cost, not only operate
Simply, cost performance is the highest, therefore enhances the practicality of whole lamp.
In one preferred embodiment of this utility model, multiple LED chip 13 are connected in series by tinsel 12.Therefore
The electric current flowing through multiple LED chip 13 is the most equal, and constant current chip 14 and LED chip string are connected in series, namely constant current chip 14
It is connected in series with multiple LED chip 13, then flow through the electric current of each LED chip 13 and flow through the electric current of constant current chip 14 also
Equal, and because the constant current effect of constant current chip 14 makes size of current keep constant, the most not only make each LED chip 13
The light luminance sent keeps stable, and the light luminance also making each LED chip 13 send is identical.
Further, substrate 11 is ceramic substrate, and ceramic substrate refers to that Copper Foil is at high temperature bonded directly to aluminium oxide
(Al2O3) the special process plate or in aluminium nitride (AlN) ceramic substrate surface (single or double).Made ultra-thin composite base
Plate has a good electrical insulation performance, high thermal conduction characteristic, excellent solderability and high adhesive strength, and can be as pcb board
Can etch various figure, have a biggest current capacity, ceramic substrate also has high heat radiation, low thermal resistance, life-span length, resistance to simultaneously
The advantages such as voltage.And multiple LED chip 13 and constant current chip 14 are when energising uses, substantial amounts of heat can be produced, if not taking
Cooling measure, then be easier to burn out chip, and this is the most extremely unfavorable for using, and has high heat radiation, low grade fever in view of ceramic substrate
The advantage of resistance, therefore, may be used as carrying multiple LED chip 13 and the carrier of constant current chip 14, and because of its life-span length, resistance to
The advantage of voltage, by increasing capacitance it is possible to increase use the time, very big improves practical value.Similar with ceramic substrate, process for sapphire-based
Plate is equally applicable.
Further, multiple LED chip 13 spaced sets, so when LED chip 13 is lighted in energising, at the photograph of light
In the range of penetrating, it is the most uniform that light is distributed.
Further, the outer surface of substrate 11 is coated with fluorescent glue 15, and substrate 11 positive pole pin 16 and negative pin 17 are naked
It is exposed to outside fluorescent glue 15.Fluorescent glue 15 is bright in luster fluorescence, can strengthen visual effect, but have no effect on printing opacity, and, bag
It is covered with the substrate 11 of fluorescent glue 15 so that the light that LED chip 13 sends can go out light through fluorescent glue 360 °, increases light
Range of exposures.
When specifically applying, it is possible to use the LED strand 1 carrying constant current chip is fabricated to LED filament lamp bar lamp 2, including
Lamp holder 21, drives power supply 22, cell-shell 23, wick column 24, carries the LED strand 1 of constant current chip, wire 25.Lamp holder 21 and bubble
Shell 23 connects, and drives power supply 22 to be arranged in lamp holder 21, and wick column 24 is arranged in cell-shell 23, carries the LED of constant current chip
Strand 1 is welded in wick column 24 and is electrically connected with driving power supply 22 by wire 25, thus constitutes a complete LED filament
Lamp bar lamp 2.The filament bar of this LED filament lamp bar lamp 2 is the LED strand carrying constant current chip, when carrying out whole lamp and producing,
Drive power supply 22 to can simply be common power, replace special constant-current to drive power supply to use with this, the driving power supply of use 22 with
Special constant-current power supply is compared, and volume is less, it is easier to producing and cost performance is higher, therefore practicality is higher.
