Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments this utility model is described in detail.It should be noted that not rushing
In the case of prominent, the feature in following embodiment and embodiment can be mutually combined.
As Figure 1-3, the S type LEDs in the one of embodiment of this utility model include 10 He of flexible circuit board
At least two groups LED lamp bead groups 20, wherein, the flexible circuit board 10 is by least two sections 12 groups S-type of flexible circuitry Slab elements
Into the underrun of the flexible circuit board 10 is etched in layers of copper and is formed with four main power sources extended along light bar length direction
Line, they are cathode power supply line L respectively+, the first anode power cord LR-, the second anode power cord LG-And the 3rd anode power cord
LB-.The top surface of the flexible circuit board 10 is formed with the first connecting wire N by the etching in layers of copperR, the second connecting wire NGAnd the 3rd connecting wire NB.Certainly, if monochromatic LED lamp bead, main power line is two, and connecting wire is also two kinds.It is more excellent
Ground, the width of the flexible circuit board 10 is 8mm, compares product of the width on market for 10mm or 12mm, and cost is reduced
20-40%；Also, more convenient in the limited space mounting of advertisement light emitting word, bending effect is good, and light source luminescent is evenly.
At least two groups LED lamp bead groups 20 are separately positioned at least top surface of two sections of flexible circuitry Slab elements 12, every group of LED
There are some (the present embodiment is three) LED lamp beads 22 in lamp bead group 20, the LED lamp bead 22 in the present embodiment is RGB three-primary color LEDs
Lamp bead, which includes emitting red light chip 22a, green emitting chip 22b and blue luminescence chip 22c.More preferably, the LED
Pearl 22 is 5050RGB lamp beads, by external controller, can become many (7) and plant color and various flickers change.LED lamp bead 22
Can also be 5050 monochromatic LED lamp beads.
With reference to shown in Fig. 4, the emitting red light chip 22a Jing first of three LEDs lamp beads 22 of every group of LED lamp bead group 20 connect
Wire NRSeries connection, one end and cathode power supply line L after series connection+It is connected, the other end and the first anode power cord LR-It is connected, every group of LED
Green emitting chip 22b second connecting wires N of Jing of three LEDs lamp beads 22 of lamp bead group 20GSeries connection, after series connection one end with just
Pole power line L+It is connected, the other end and the second anode power cord LG-It is connected, three LEDs lamp beads 22 of every group of LED lamp bead group 20
The 3rd connecting wires N of blue luminescence chip 22c JingBSeries connection, one end and cathode power supply line L after series connection+It is connected, the other end and the 3rd
Anode power cord LB-It is connected.By in the first anode power cord LR-, the second anode power cord LG-And the 3rd anode power cord LB-It is defeated
Enter different electric currents, LED lamp bead 22 can send the light of different colours.
Inventor of the present utility model has found, due to the LED lamp bead negligible amounts of every group of LED lamp bead group, generally 3 or
6, the electric current that connecting wire flows through is less, therefore the thickness of connecting wire is reduced on the basis of original, and main power line is
Mains supply line, current needs are big, therefore increase the thickness of main power line on the basis of original, can so reduce decay,
Product illumination effect is good, lights basically identical.So as to solve in the case where cost is not increased, terminal voltage decay is larger to ask
Topic.More preferably, the main power line L+、LR-、LG-、LB-Thickness be 50 μm～70 μm, connecting wire NR-、N G-、N B-
Thickness be 8 μm～28 μm.It is further preferred that the main power line L+、LR-、LG-、LB-Thickness be 55 μm～65 μm, institute
State connecting wire NR-、N G-、N B-Thickness be 13 μm～23 μm.So design is tested after making finished product, supply voltage 12V, and 5
Rice length ends voltage is 10V, and decay 2V；Supply voltage 24V, 5 meters of length ends voltages are 22.5V, and decay 1.5V, and decay is big
Big to reduce, product illumination effect is good, lights basically identical.And, 10 top layer copper thickness of flexible circuit board+bottom copper is thick total 68 μm
FPCB products (thick 35 μm of top layer copper 35 μm+bottom of thickness copper adds up to 70 μm) cost on～88 μm, with market is essentially the same.
Inventor of the present utility model has found, when LED lamp bead 22 only has one single chip luminous, the power supply foot of main power line
It is enough, but when red luminescence chip 22a, green emitting chip 22b and blue luminescence chip 22c are lighted together, voltage requirements meeting
Become big, the supply voltage decay of main power line becomes big, affects illumination effect.Therefore, in order to reduce supply voltage decay, improve
LED illumination effects, the top surface of the flexible circuit board 10 have an auxiliary power supply line N extended along light bar length direction+, this is auxiliary
Help power line N+With the cathode power supply line L+It is in parallel.So, equivalent to increased cathode power supply line L+Cross-sectional area, so as to
Significantly reduce decay.
More preferably, some LEDs also including some dropping resistors 30, in dropping resistor 30 and every group of LED lamp bead group 20
Pearl 22 is connected.
To sum up, S types LED of the present utility model has the advantages that：
(1) by the thickness of increase main power line, the thickness of connecting wire is reduced, is realized in the situation for not increasing cost
It is lower to solve the problems, such as that terminal voltage decay is larger；
(2) auxiliary power supply line is increased by top surface in flexible circuit board, solve when red luminescence chip 22a,
When green emitting chip 22b and blue luminescence chip 22c are lighted together, the problem of voltage attenuation, improves illumination effect；
