Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

This plain type LED lamp, including lamp body 1, lamp body 1 is connected with lamp stand 2 or lamp holder 3, be equipped with the LED lamp strip subassembly including LED lamp strip 5 in the lamp body 1, be used for connecting the bottom and the lateral part that are used for connecting external power source on two inserted sheets or the lamp holder of external power source on the lamp stand 2, and be equipped with the current-limiting circuit who is used for controlling the electric current size that flows through LED lamp strip subassembly between the LED lamp strip subassembly, be equipped with at least one current-limiting element 4 on the current-limiting circuit, at least one end on at least one current-limiting element 4 and the one end high temperature butt fusion.

Because the mode of fast cooling after high-temperature welding is adopted, the current limiting element 4 and the lead 8 can be firmly connected together without other welding materials, the welding materials required for connecting the two ends are saved, and the welding process is also saved.

Preferably, the welded end of the current limiting element and the welded end of the lead connected with the end are parallel to each other and are arranged in a stacked manner, wherein the stacked manner means that areas overlapped with each other exist when the two end parts are matched, a certain welding surface is ensured during welding, the firmness of the two end parts after welding is ensured, and in addition, because one of the two end parts does not need to be wound on the other end part, the working procedure is saved, and the production efficiency is improved.

Specifically, the current limiting elements 4 in the current limiting circuit may be resistors only, and the number of the current limiting elements may be single or multiple, or of course, the current limiting circuit may be capacitors only, and the number of the current limiting elements may be single or multiple, or of course, the current limiting circuit may have both resistors and capacitors, and the number of the current limiting elements may be single or multiple, and the connection modes of the current limiting elements 4 in the current limiting circuit may also be various, that is, the current limiting circuit may have a form of only connecting in series, a form of only connecting in parallel, or a form of both connecting in series and connecting in parallel.

It should be noted that the resistor and the capacitor have respective advantages when used for current limiting, and for the resistor, the resistor is a linear element, so that the resistor has the advantages of no change of power supply waveform, low harmonic wave and high power factor, and can also be applied to various dimmers, so that the circuit reliability is high; for the capacitor, the capacitor is used for limiting current and has the advantages of small volume, low power consumption and good high-frequency response; when the current limiting circuit simultaneously uses the resistor and the capacitor for current limiting, the current limiting circuit has the advantages of reducing circuit loss, reducing resistance power and improving circuit efficiency, so that the current limiting element in the current limiting circuit can be set differently according to requirements.

In addition, it should be noted that the LED light bar assembly herein may include one or more LED light bars, and the LED light bar herein may refer to either a direct current type LED light bar or an alternating current type LED light bar.

Preferably, the at least one current limiting element is sleeved with the insulating sleeve 7, so that normal and safe operation of the current limiting element 4 is guaranteed, influence of heat emitted by the current limiting element 4 on light efficiency of a light bar in the LED light bar assembly due to the fact that the heat cannot be timely discharged outwards can be prevented, and meanwhile, the temperature of adhesive at the sealing connection position of the lamp shell 1 and the lamp holder 2 or the lamp holder 3 is heated to influence the adhesion degree of the adhesive.

As shown in fig. 6 to 7, when the light bars in the LED light bar assembly in the LED lamp are AC light bars, the LED lamp becomes an AC LED lamp, and can be directly connected to an AC power source with a voltage range of 12 v to 300 v as an external power source without a special AC/DC converter.

In addition, here, an ac light bar is used, not a dc light bar, which also consists in: still need be provided with PCB drive plate 6 in the LED lamp of direct current type, not only increased the circuit complexity, should install the drive plate in lamp holder or lamp stand and damage easily moreover, the security is not high, and is with high costs, and the technology is connected complicatedly, can simplify the circuit greatly through adopting the interchange lamp strip, material saving and cost again simultaneously have improved the production automation level.

In this case, the current limiting element is a resistor, and the range is selected to be 1K-100K omega.

In this case, the current limiting element is a capacitor, and the range is 0.01-0.1 uF.

When the alternating current LED lamp is used as a household appliance type LED indicator lamp, the LED lamp bar assembly has low power.

The reason why the household appliance type LED indicator lamp is also an AC type LED lamp is that a general LED is driven by a DC current, and a driving module is required to convert an AC into a DC in a production process to light the LED. The production process is complex, the working procedures are multiple, one common LED lamp needs dozens of or hundreds of components for driving and matching, the cost performance is not high, and particularly, the power of the common LED lamp is not large, generally 0.5W-5W can meet the operating requirements of products, so that the conversion efficiency is not high, the luminous efficiency is low in the application of converting alternating current into direct current, the national energy-saving and emission-reduction requirements cannot be really met, and the latest instruction of European Union on for eliminating the lighting source below 85lm/W cannot be met.

When the current limiting element is a resistor, a precision resistor with the power of 1W to 2W and the precision difference of less than 1 percent is adopted, and the current limiting element has the advantages of low power consumption and small size.

It should be noted that the size of the resistor in the current limiting circuit is set according to the voltage of an external ac power supply, the number of the ac light bars, the total number of the LED chips included in the ac light bars, the number of the LED chips used for rectification, the rated voltage of the LED chips, and the rated current of the LED chips, and the calculation of the resistor provides a guarantee for accurately controlling the operation of the LED light bar assembly under the rated operating voltage and the rated operating current.

The following is an example of a specific calculation method for determining the magnitude of the resistance in the current limiting circuit:

as shown in fig. 8, from the product information provided by the light bar vendor:

1. the light bar is internally composed of 16PCS 9V LED chips (different products can use different light bar parameters);

2. the 16PCS chip has 4PCS as rectification;

3. the rated current of the LED lamp strip is 6 mA;

when the external alternating-current power supply voltage is 230V, the resistance value of the current-limiting resistor is determined as follows:

1. the rectified voltage of AC230V is approximately: 230 × 1.1 ═ 253V;

2. LED voltage: (16-4) × 9 ═ 108V;

3. calculating the current limiting resistance value: r0 ═ (253-;

4. calculating the power consumption of the current limiting resistor: p ═ UI ═ I × R ═ 0.006 × 0.006 × 24000 ═ 0.864W;

finally, the actually selected current limiting resistor can be: the rated power is 1W, and the resistance is 24K omega.

Additionally, preferably, the alternating current light bar in the LED light bar assembly is an LED high-temperature high-voltage light bar.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.

Although the terms lamp housing 1, lamp base 2, lamp cap 3, current limiting element 4, LED light bar 5, PCB driver board 6, insulating sleeve 7, wire 8, etc. are used more herein, the possibility of using other terms is not excluded.
