Along with development of science and technology, LED lamp cost constantly reduces, and the LED light fixture begins to enter huge numbers of families, and LED lamp little power consumption, light efficiency height, life-span be long, easily assembling, easy care, greatly facilitates people's life.From supply power voltage, the LED light fixture both can use high voltage supply also can use low-voltage power supply, in order directly to use line voltage, the high-voltage lamp bar uses high voltage supply, but the power supply of common high-voltage lamp bar is gone up and will directly LED lamp group be powered behind the civil power alternating current process rectifying and wave-filtering, and when voltage instability, electric current will fluctuate with input voltage fluctuation, cause LED operating current instability and damage or thoroughly damage, and then cause the whole LED lamp life to shorten.Because general high-voltage LED lamp bar uses a plurality of LED lamp grains to be in series, the infringement of a LED lamp grain very likely causes whole LED lamp bar thoroughly to damage, and is unavailable again.Even if under the stable voltage supply situation, along with LED service time or operating time when long, LED also can exist heating to increase, the situation that temperature raises, this often causes operating current to change, thereby the brightness that causes the LED lamp changes, and human eye will be tired easily under the LED lamp that brightness changes, and is visual poor.Therefore stable supply power voltage and supply current is vital to the high-voltage lamp bar.
On structure, many high pressure light fixtures are made to go up and are used the PCV extrusion moulding in addition, and pliability is poor, meets the low temperature hardening, and not folding is necessary to be improved at above-mentioned shortcoming.
The utility model content
The utility model provides a kind of high voltage and constant current LED lamp bar, described high voltage and constant current LED lamp bar comprises LED lamp group, described LED lamp group connects constant-current circuit, and rectification circuit, filter circuit, booster circuit and the voltage stabilizing circuit power supply of alternating voltage through connecting successively is input to LED lamp group input.
Particularly, described LED lamp group is in series by plurality of LEDs lamp grain.
Particularly, described constant-current circuit uses a plurality of constant current diodes to form, and guarantees the stable of LED operating current.
Particularly, described rectification and filter circuit change into the 220V direct current with 220V input AC electricity, and described booster circuit and voltage stabilizing circuit are converted into stable 390V direct current with the 220V direct current, as the working power of LED lamp group.
Particularly, described high voltage and constant current LED lamp strip adoption silica gel sleeve pipe, interior notes silica gel is strengthened heat conduction and pliability.
The high voltage and constant current LED lamp bar that the utility model provides, mains supply input back increases booster circuit handles, and for LED lamp bar provides higher operating voltage, thereby can connect more LED lamp grain or lamp group in parallel, increases the brightness of whole LED lamp bar.Voltage stabilizing and constant-current circuit guarantee that LED lamp bar continuous firing under stable operating voltage and operating current situation, in the useful life of having improved LED, guarantees that also the brightness of LED lamp bar keeps constant in a long time, has effectively protected human eye vision.In addition, the lamp bar is made to go up and is adopted the silica gel sleeve pipe, has strengthened thermal conductivity and the suppleness of lamp bar.Comprehensive above-mentioned situation as can be known, the high voltage and constant current LED lamp bar that the utility model provides has brightness height, visual good, long service life, heat conduction and the good advantage of suppleness.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
