Abstract
The utility model relates to high-voltage safe brightening lamps, composed of a PC (Polycarbonate) housing, a bar-shaped PCB (Printed Circuit Board), LED's (Light-Emitting Diodes), a transformer and the like. AC 200V high-frequency power supply is input into the input end of the high-frequency transformer; 24V AC is output from the output end of the high-frequency transformer, converted into DC via bridge type rectification, filtered by an electrolytic capacitor and limited by an inductor to obtain current in 240 milliampere; 16 LED groups are connected in parallel via leads, wherein each LED group comprises 6 LED's in series connection; and the current in 240 milliampere is averagely distributed so that rated current of each LED group path is 15 milliampere. The high-voltage safe brightening lamps have the advantages that structure is simple, use is highly safe, and damages of heavy current to electronic components and fire hazard caused by high-voltage sparking during high-voltage short circuit can be effectively avoided.
Description
Technical field
The utility model belongs to a kind of brightening light fixture, is a kind of LED light fixture that adopts the high-frequency High Voltage Power Supply.
Background technology
The LED guardrail pipe is to adopt high-quality ultra-bright LED light-emitting diode to form, and is mainly used in the urban look beautification function.Product has power consumption little (each is less than 1W), empty calory, the life-span is long, shock-resistant, reliability is high, energy-conserving and environment-protective, and is photochromic soft, the brightness high.Color is pure, extra long life, and average life span reaches 80,000 ~ 100,000 hours.Cardinal principle is to be realized the variation of seven kinds of colors by the red-green-blue colour mixture, adopts the pulse-width modulation of output waveform, and the duty ratio of namely regulating the conducting of LED lamp in the situation that sweep speed is very fast, utilizes the visual persistence of human eye to reach the effect of gradual change.A fluorescent tube is by the internal control chip, can segmentation change seven kinds of different colours, and produce gradual change, flickering, scan, chase, the various effects such as flowing water, fluorescent tube length can be selected arbitrarily (unit: rice).Ultraviolet radiation resisting, waterproof, protection against the tide.LED internal control charactron range of application: be particularly suitable among the large-scale dynamic light belts such as billboard background, viaduct, river, lake guardrail, contour of building, can produce gorgeous effect as rainbow.With the profile of guardrail pipe decorative constructure, can play outstanding effect of beautifying the brightening building.Fact proved, it has become a wonderful work in illuminating product, bursts forth in dynamic city.This product is LED to be placed on the PCB circuit board be arranged in a linear by red green blue order, controls with special driving chip, consists of with countless changes color and figure.Shell adopts the fire retardation PC plastic production, and intensity is high, and shock resistance is anti-aging, and antiultraviolet is put dirt, protection against the tide, and degree of protection reaches IP65.; The brightening light fixture of selling in the market is of a great variety, but all insufficient in the processing of most safeguard protections in the product use procedure, and particularly in the outdoor high-voltage electronic product, lacking a kind of employing is high pressure and safe and reliable brightening light fixture.
Summary of the invention
The utility model purpose is, for the deficiencies in the prior art, proposes a kind of high-voltage safety lightening lamp.
high-voltage safety lightening lamp of the present utility model, comprise the PC shell, PBC bar shaped wiring board, the device such as light-emitting diode and transformer forms, it is characterized in that: by the input input AC200V high frequency electric source of high frequency transformer (1), the output of high frequency transformer (1), the alternating current of output low pressure AC24V, pass through again bridge rectifier (2) and change direct current into, carry out filtering for rectification direct current out by electrochemical capacitor (4), inductor (3) current limliting, obtain the electric current of 240 milliamperes, connect 16 groups of parallel connections through wire, the light-emitting diode mean allocation electric current of 6 pearl series connection, making its every road electric current is the rated current of 15 milliamperes.
The present invention's beneficial effect compared with prior art: have simple in structurely, during use, security performance is high, and the large electric current that causes in the time of can efficiently solving high voltage short circuit damages the advantages such as fire incident that electronic device, high voltage arc cause.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing, but embodiments of the present invention are not limited to this.
Fig. 1-technical scheme circuit diagram
In figure: high frequency transformer (1), bridge rectifier (2), inductor (3), electrochemical capacitor (4), 16 groups of 6 pearl series LED light sources (5) in parallel.
Embodiment
as shown in Figure 1: high-voltage safety lightening lamp of the present utility model, comprise the PC shell, PBC bar shaped wiring board, the device such as light-emitting diode and transformer forms, : by the input input AC200V high frequency electric source of high frequency transformer (1), the output of high frequency transformer (1), the alternating current of output low pressure AC24V, pass through again bridge rectifier (2) and change direct current into, carry out filtering for rectification direct current out by electrochemical capacitor (4), inductor (3) current limliting, obtain the electric current of 240 milliamperes, connect 16 groups of parallel connections through wire, the light-emitting diode mean allocation electric current of 6 pearl series connection, 15 milliamperes of rated current during work that to make its every road electric current be diode.High-voltage safety lightening lamp of the present invention is comprised of four parts: high frequency transformer, rectifying and wave-filtering, current-limiting inductance and load light-emitting diode.High frequency transformer provides specified power voltage and electric current for load, consists of full-wave rectifier filter with fast recovery diode and electrochemical capacitor and becomes direct current, and direct voltage provides 240 milliamperes of electric current powering loads through current-limiting inductance and resistance.The light-emitting diode that load is 0.05W by 16 groups of 6 pearl series connection power in parallel consists of.This fitting structure is simple, and during use, security performance is high, also can not form the loop even human body directly touches, and electric shock accidents can not occur, and water inlet can not make damage of product yet, more can not cause fire.Be the safest outdoor lamp of a existing market, project installation does not need the numerous and diverse power line of cloth, thereby saves engineering cost, shortens the construction time limit, increases work efficiency.The large electric current damage electronic device that this brightening LED light fixture causes when at first efficiently solving high voltage short circuit, the fire incident that high voltage arc causes, secondly carry out again on this basis skill upgrading and structural improvement, develop in 50 meters to 100 meters, Engineering Speciality type, need not to carry out the other layout of power line when product is installed, only need product to couple together and connect power supplying from one direction.
