Description

Box-shaped led light source circuit

(1) technical field

The present invention relates to a kind of lighting apparatus, particularly relate to a kind of light fixture.

(2) background technology

Though the ZL2010201054557 circuit of light sources has certain light efficiency advantage, defective also obviously exists, i.e. the effect of control circuit is not obvious, the version of power supply line and the quality problems of covering copper conductor are all restricting the further raising of luminous efficiency.

(3) summary of the invention

The objective of the invention is, overcome the deficiency of prior art, a kind of in-fighting is low, light efficiency is high for light trade provides, and is easy to the box-shaped led light source circuit of making and safeguarding.

The present technique scheme by circuit of light sources, LED, cover copper conductor and form.Circuit of light sources is formed the LED1 of a box-shaped by a plurality of LED, and two unit in the square carry out series and parallel respectively, then parallel connection or a plurality of LEDn arranged side by side again.LEDn arranged side by side has own special-purpose power supply line, and two nodes of power supply line on this square circuit can be located at the arbitrfary point of both positive and negative polarity.The power that covers copper conductor and circuit of light sources is complementary and all to cover copper conductor wide.

Tangible beneficial effect is implemented to have received in this programme ground:

1. simplified circuit structure, cost is low, the life-span is long, is easy to manufacture, for optimal design, exploiting market provides convenience.

2. in-fighting is low, light efficiency is high, and it is balanced that the voltage before and after the circuit of light sources more becomes, and luminous efficiency has improved more than 15% on year-on-year basis, has been promoted to 115Lm.

The present invention is applicable to supply voltage 12V, and is all light fixtures of light emitting source with the low-power LED, and promotion prospect is good.

(5) embodiment

Below in conjunction with accompanying drawing and embodiment, the present invention is done description further:

As shown in Figure 2:

Circuit block diagram is made up of solar energy pole plate, intelligent controller, storage battery, circuit of light sources, LED.The solar energy pole plate is converted into electric energy with the solar energy of accepting, and is charge in batteries via intelligent controller, and what of the existing electric weight of automatic detection intelligent controller have, thereby implements overshoot, cross and put protection and close automatically or the multinomial function of power-on.When intelligent controller when storage battery sends open command, the electric energy of storage battery will be that circuit of light sources is carried controlled electric energy constantly via intelligent controller, thereby send constant light.

As shown in Figure 3:

Said circuit of light sources 1 covers copper conductor 3 by LED2 to be formed.

Said a plurality of LED2 is at least 16.

The a plurality of LEDn of said parallel connection are that level vertically to the LED1 of the same quantity of need parallel connection, meets the box-shaped parallel circuits of power requirement to being parallel with n LED1 with formation.

Said box-shaped parallel circuits should be no more than 15W, otherwise after should being divided into several blockage circuit, becomes the circuit of light sources of big square more side by side.

Said a plurality of LEDn arranged side by side do, the LED1 of n same power is in juxtaposition, and meet discrete again box-shaped of power requirement and column circuits with formation.

Said arbitrfary point should be located at square circuit position comparatively placed in the middle.

The optimal design of series and parallel structure and power supply line; Not only overcome a drawback that LED damage, whole series do not work; Also improved the ability of circuit of light sources self control voltage pre-and-post equalization significantly; For good condition has been created in the cancellation of control circuit ground, thereby improve luminous efficiency greatly, reduced maintenance and manufacturing cost.

Said LED2 is the small-power white light-emitting diodes, except that other conditions, also should propose the requirement and the strict incoming test of luminous efficiency when buying is ordered goods.

Saidly cover the aggregation that copper conductor 3 is circuit of light sources leads, but its quality concept often ignored by the people and listen the autonomous arrangement by wiring board specialized factory, its result often causes the quality of lead low, thereby has influenced luminous efficiency.Even experiment showed, the circuit of light sources that other conditionally completes are identical, the luminous efficiency of covering the copper mass difference is low.This is consistent with other appliance powers with the matching relationship of diameter of wire, so the power that requires to cover copper conductor 3 and circuit of light sources is complementary.

Saidly be complementary, for the circuit of light sources of 20W～100W, the thickness that covers copper conductor 3 should be 3～8 millimeters of 35～50 microns, width, and all to cover copper conductor 3 wide, even it is no exception to cover the lead of copper periphery.

Embodiment 1

As shown in Figure 4:

For the circuit of light sources of square or circular lamp holder, should adopt the mode of parallelly connected a plurality of LEDn, promptly level vertically to the LED1 of the same quantity of need parallel connection, meets the box-shaped parallel circuits of power requirement to being parallel with n LED1 with formation.

Because of the not enough 15W of the square circuit after the parallel connection, so the power supply line is two, two nodes of power supply line on this square circuit should be located at circuit position comparatively placed in the middle.

Said LED2 should select the low-power diode below the W for use; Should carry out personal Electrostatic protection work during assembly welding; As dress antistatic wrist strap, antistatic clothing, anti-static shoes, use antistatic flatiron etc., in order to avoid LED2 is caused damage, thus bring unnecessary trouble.

If the employing printed circuit, also considered is covered the quality problems of copper conductor 3, that is to say, should cover the thickness and the width of copper conductor 3 according to the size design of design power, and keeps that all to cover copper conductor 3 wide.

If produce in enormous quantities, also reply is covered copper and is carried out silver-plated processing in advance.

At last, still need and the back side of wiring board finished product is implemented the spraying coating process of " three anti-lacquers ".

Embodiment 2

As shown in Figure 5:

For the circuit of light sources of rectangle lamp holder, should adopt the mode of a plurality of LEDn arranged side by side, that is to say, the LED1 of three same power is in juxtaposition, meet the discrete again box-shaped of power requirement and column circuits promptly is with formation.Because of the equal not enough 15W of three square circuits arranged side by side, so establish the power supply line six roots of sensation.
