Abstract
The utility model relates to a cold light source lighting device, which comprises a bridge type rectification circuit consisting of luminous diodes, and a group of lighting units whose output ends areconnected and which consist of luminous diodes, wherein a plurality of lighting units are connected in series to form the cold light source lighting device, and the input ends are connected with thefrequency doubler. The cold light source lighting device has the advantages that firstly, four luminous diodes (LED) are used as the rectification device, and meanwhile, a plurality of LEDs are connected in series as the cold light source lighting unit of a load, and other electric energy is totally conversed into light energy except the filtration energy storage function of a capacitor and the self loss of LED, secondly, the lighting device is a capacitive load, and can greatly improve the current electric network power factor, thirdly, a doubling circuit is adopted, and transforms 50Hz of commercial powerinto into 100Hz, and the cold light source lighting device can be used for domestic and similar lighting systems for long term object (word) reading of human eyes.
Description
Technical field:
The utility model relates to the power lighting device, particularly a kind of a kind of cold light source lighting device that utilizes light emitting diode to form.
Background technology:
At present, as a kind of energy-saving illumination device, light emitting diode has been used for lamp decoration system and public lighting lamp system, but it at first needs through a fairing, converts the civil power that exchanges to unidirectional direct current and just can use.Therefore, it is high that it exists power consumption, defectives such as use cost height.
The utility model content
The purpose of this utility model is exactly in order to overcome the high defective of power consumption that prior art exists, a kind of cold light source lighting device of proposition.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of cold light source lighting device, it is characterized in that it comprises that a bridge rectifier of being made up of light emitting diode and bridge rectifier output connect one group of lighting unit that light emitting diode is formed of (series, parallel all can), the bridge rectifier output is parallel with the filtering energy-storage capacitor.
According to above-mentioned basic technical scheme, further technical scheme is: comprise that at least two lighting units are through connecting to form the lighting unit group, wherein the input of the bridge rectifier in all lighting units is connected in series, form the input of an input of input of bridge rectifier in first lighting unit and the bridge rectifier in last lighting unit as the lighting unit group, the input of lighting unit group connects a frequency multiplier.
Owing to adopted above technical scheme, made to the utlity model has following advantage:
1. utilize 4 light emitting diodes (LED) self as rectifying device, be connected in series the cold light source lighting unit of a plurality of LED simultaneously as load, a plurality of as required cold light source lighting units can be connected into the public lighting lamp system of a practicality, can not need transformer directly to insert civil power 220V as 20 lighting unit series connection and use.By adjusting number, can change and insert the required cold light source lighting unit group number of civil power use as the LED of load.This method for designing circuit except that electric capacity as the filtering energy storage effect, none other energy dissipation device, promptly except the LED own loss, all the other electric energy all are converted to luminous energy, have improved electric light transformation of energy rate greatly, thereby have reached energy-conserving action.
2. this illuminator is a capacitive load, uses in public lighting in a large number and can improve present power factor of electric network greatly, reduces reactive power and also can play energy-conserving action;
3. can conveniently adopt the different capacity led chip integrated by this line principle, constitute different occasions public lighting light fixture that use, different capacity.
4. can adopt to flexibly connect, it is made different shape.
5. consider that 4 rectification LED are half-wave conductings, can adopt frequency multiplier circuit, civil power 50Hz is converted into more than the 100Hz, insert this LED system again, promptly can be used for human eye and know the family expenses of thing (word) and the illuminator of similar applications for a long time.
Description of drawings:
Fig. 1 is the structure principle chart of the utility model embodiment one;
Fig. 2 is the structure principle chart of the utility model embodiment two.
The specific embodiment:
Embodiment one, as shown in Figure 1, the cold light source lighting device that the utility model provides, comprise 1,2 ... n group cold light source lighting unit, each cold light source lighting unit constitutes bridge rectifier by 4 light emitting diodes (LED), the output of bridge rectifier is connected in series a plurality of LED simultaneously as load, and the LED load is parallel with capacitor C.
The input of the bridge rectifier among Fig. 1 in all lighting units is connected in series, form the input of an input of input of bridge rectifier in first lighting unit and the bridge rectifier in last lighting unit, insert the 220V civil power as the lighting unit group.
Embodiment two, as shown in Figure 2, follow-on cold light source lighting device that the utility model provides, basic structure is with embodiment one, difference is: the input of lighting unit group connects a frequency multiplier, frequency multiplier is with 220V, and the civil power of 50HZ converts the power supply of 100HZ to, promptly can be used for human eye and knows the family expenses of thing (word) and the illuminator of similar applications for a long time.
