Abstract
The invention provides a high-voltage safe brightening lamp which comprises a PC (Personal computer) shell, a PBC (Peripheral Bus Computer) strip-type circuit board, light-emitting diodes, a transformer and the like, wherein the input end of the high-frequency transformer inputs an AC (Alternating Current) 200V high frequency power source, and the output end of the high-frequency transformer outputs a low-voltage AC20V alternating current which is converted into a direct current by virtue of a bridge rectifier; the direct current is filtered by an electrolytic capacitor and limited by an inductor, so as to obtain a 240mA current; and 16 groups of light-emitting diodes connected in parallel and 6 groups of light-emitting diodes connected in series are connected by virtue of wires, and are uniformly distributed, so that the current of each path is a 15mA rated current. The high-voltage safe brightening lamp has the advantages of simple structure, high safety performance in use, capability of effectively solving electronic device damage caused by a heavy current during high-voltage short circuit and fire accidents caused by high-voltage fire striking, and the like.
Description
Technical field
The invention 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 the 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 the 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, with special driving chip control, 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, and lacking a kind of employing and be high pressure is again safe and reliable brightening light fixture.
Summary of the invention
The object of the invention 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 invention, 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 240 milliamperes electric current, connect 16 groups of parallel connections through wire, the light-emitting diode mean allocation electric current of 6 pearls series connection, making its every road electric current is 15 milliamperes rated current.
The present invention's beneficial effect compared with prior art: have simple in structurely, security performance is high during use, 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
Among the 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 invention, 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 240 milliamperes electric current, connect 16 groups of parallel connections through wire, 15 milliamperes of rated current when the light-emitting diode mean allocation electric current of 6 pearls series connection, 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 pearls series connection power in parallel consists of.This fitting structure is simple, and security performance is high during use, 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 on the Engineering Speciality type, need not when product is installed, to carry out the other layout of power line, only need product to couple together and connect power supplying from one direction.
