Abstract

A kind of chip inductor LED lamp panel with resettable fuse, it is made up of chip inductor, rectifier bridge, LED bead string, resettable fuse, aluminium base, chip inductor, rectifier bridge, LED bead string, resettable fuse are welded on aluminium base jointly, and resettable fuse is connected between the cathode output end of rectifier bridge and the positive pole of LED bead string；Scheme of the present utility model is employed, overcoming chip inductor LED lamp panel does not have the shortcomings that overcurrent protection, is particularly suitable for high-power light-projecting lamp use.

Description

A kind of chip inductor LED lamp panel with resettable fuse

Technical field

A kind of LED one lamp plate is the utility model is related to, it is especially a kind of to use chip inductor with resettable fuse A kind of efficient high power LED one lamp plates realized.

Background technology

At present, LED is had started to popularize, and the structure of LED is typically made up of power supply, lamp plate, shell three parts, on the market Also there are the integral lamp plate for being combined together power supply and lamp plate, such as new capacitance-resistance lamp plate, although simple and reliable and LED lamp bead is very It is durable, but resistance will consume a part of electric energy after all, reduce electric energy service efficiency, it is preferably electric because inductance is perceptual Sense only consumes idle, i.e., with systems exchange energy, does not consume active power, therefore in order to improve the service efficiency of electric energy, city There is the LED using current limit by inductance on face, but be not integral lamp plate, also there is the integral lamp plate of design, but because system is sometimes unexpected Producing overcurrent influences the lamp bead life-span.

Utility model content

In order to overcome the LED one lamp plate for using chip inductor to influence lamp bead because system overvoltage suddenly sometimes produces overcurrent The shortcomings that life-span, the utility model proposes a kind of chip inductor LED lamp panel with resettable fuse to solve this problem, its Good effect is：Using a kind of chip inductor LED lamp panel with resettable fuse, the LED electric energy of current limit by inductance has been developed The characteristics of utilization ratio is high, while the safety for protecting LED bead string is disconnected in the unexpected overcurrent of system.

Technical scheme is used by the utility model solves its technical problem：

A kind of chip inductor LED lamp panel with resettable fuse of the present utility model, by chip inductor, rectifier bridge, LED Lamp bead string, resettable fuse, aluminium base composition, chip inductor, rectifier bridge, LED bead string, resettable fuse weld jointly On aluminium base, resettable fuse is connected between the cathode output end of rectifier bridge and the positive pole of LED bead string.

The technical solution adopted in the utility model will coordinate accompanying drawing to elaborate in a particular embodiment.

Embodiment

In the embodiment in figure 1, we exemplified by implementing a kind of chip inductor LED lamp panel with resettable fuse to this Utility model further illustrates：

Fig. 1 is a kind of chip inductor LED lamp panel circuit theory diagrams with resettable fuse of the present utility model, we with Make and elaborate exemplified by a 100 watts of light projector lamp plate, AC power 1 is common 220v power supplys in figure, chip inductor 2 For high current chip inductor, from single 1000uH high current chip inductor, quantity is 50, according to the л fL of induction reactance formula X=2 Calculate, induction reactance is 15.7 ohm after series connection, plus the resistance of inductance in itself, is fully able to have the function that current limliting, rectifier bridge 3 is High-voltage rectifier bridge, inside are connected using four commutation diodes, can select 600V or 1000V, 2 peace large chip paster full-bridges, LED bead string 4 is connected into a string, then parallel connection 6 is gone here and there again, that is, is used existing from 5630 lamp bead of 3v pasters 360 by 60 There are the more simultaneously structure technologies of lamp bead arrangement string more of Projecting Lamp（Because position is limited, single string structure is only depicted in figure）, per LEDs 0.5 watt of lamp bead power, the selection work voltage 250v of resettable fuse 5, action current 2.5A paster.By chip inductor 2nd, rectifier bridge 3, LED bead string 4, resettable fuse 5 are pressed schematic diagram in figure and connected, and energization can work, and its principle is：Exchange The alternating current of power supply 1 turns into Rectified alternating current by the current limliting of chip inductor 2, then by the rectification of rectifier bridge 2, in the positive pole of rectifier bridge Resettable fuse 5 is accessed between the positive pole of output end and LED bead string 4, when the operating current of lamp bead string 4 increases suddenly, Resettable fuse 5 disconnects, and protects the safety of LED bead string.

Fig. 2 is a kind of chip inductor LED lamp panel structure schematic diagram with resettable fuse of the present utility model, is pasted in figure Piece inductance 2, rectifier bridge 3, LED bead string 4, resettable fuse 5 are arranged on aluminium base 5, and AC power incoming end 7 is aluminium base Two solder joints on plate 6, are directly accessed for AC power 1, and screw hole 8 is distributed near the corner of aluminium base 6, for by aluminium Substrate is fixed on a heat sink, and partial inductance and part lamp bead, and circuit cabling in detail are only depicted because position is limited, in figure It is not drawn into, as long as making aluminium base 6 according to Fig. 1 circuit theory diagrams, can buys whole original papers in Taobao, in aluminium base Upper each element is welded on 6, this be one of ordinary skill in the field with regard to the thing that can be done, will not be described in detail herein.

The one piece of lamp plate made above measured power under normal voltage 220v is 100 watts or so, can be used for street lamp etc. It is less demanding to stroboscopic but to the high occasion of life requirements, it is necessary to the lamp plate of other wattages, the parameter of its original paper can be different, can Calculate as the case may be.
