Description

A kind of LED health energy-saving lamp

Technical field

The utility model relates to the lighting apparatus technical field, particularly a kind of LED health energy-saving lamp.

Background technology

Indispensable apparatus when as everyone knows, desk lamp is students study.The common desk lamp that occurs on the market now all exists use to carry inconvenience or amount of battery consumption is big, and cost of use is higher, and the brightness of light is too high, more dazzlingly causes visual fatigue easily, and problem such as the lamp holder volume is big.

The LED lamp is as third generation lighting technology behind incandescent lamp, fluorescent lamp, has energy-saving and environmental protection, safe and reliable characteristics.And existing LED electricity-saving lamp technology is not mature enough, and the defect map of its drive circuit is present:

1, simple resistance-capacitance depressurization causes its brightness to produce light and shade along with the fluctuation of civil power and change, and LED still has the twilight sunset flicker after mains switch breaks off, and can't eliminate, again because of can not voltage stabilizing causing rapid wear;

2, have the drive circuit cost height of voltage stabilizing function, be unfavorable for penetration and promotion; Also exist simultaneously mains switch disconnection back LED and still have the flicker of static twilight sunset, shorten the LED life-span;

3, after mains switch breaks off, when thunder and lightning touches electrical network or externally fed raises suddenly, when not using, drive circuit still might damage.

Therefore, design a kind of efficient, health, energy-conservation, a kind of LED health energy-saving lamp that no stroboscopic, suitable student use is a problem of needing solution badly.

The utility model content

The purpose of the utility model provides a kind of LED health energy-saving lamp, and it can solve the deficiency that exists in the known technology.

The technical scheme of the utility model is:

A kind of LED health energy-saving lamp; Comprise lamp socket, lamp bracket, lamp holder and electric supply installation; Lamp bracket and electric supply installation are installed on the lamp socket; Lamp holder is installed on the lamp bracket, installation and control circuit in the lamp socket, said control circuit comprises reduction voltage circuit, rectification circuit, filter circuit, voltage stabilizing circuit, relay circuit and LED control circuit successively; The bridge rectifier that said rectification circuit is made up of D5-D8, the output of rectification circuit also meets a filter capacitor C2 and a voltage stabilizing didoe DW2; Said LED control circuit is made up of bridge rectifier, capacitor filter and LED lamp string; Filter capacitor C1 two ends in the LED control circuit also meet discharge resistance R1.The utility model adopts the soft starting circuit design, makes LED variable gradually, avoids the surge current of power connection moment that LED and benchmark voltage stabilizing didoe are caused damage.The filter capacitor two termination discharge resistances of while in the LED control circuit, the external power switch of can releasing break off the residual charge in the filter capacitor of back, thereby make the LED lamp behind deenergization, thoroughly extinguish, and do not have any twilight sunset, stroboscopic extremely.

The characteristic of the utility model is that also said relay circuit is made up of the relay of two parallel connections, and its normally opened contact connects two inputs of bridge rectifier in the LED control circuit respectively.Two miniature relays have been increased like this; Break off simultaneously because of losing power supply when externally mains switch breaks off; Make the direct drive circuit of back break off with the external world up hill and dale; Thereby static is disappeared, has well protected LED, and can alleviate thunder and lightning or external voltage burst raise cause to this damage of circuit effect.

Another program, said relay circuit adopt a relay with double-contact to realize.

The characteristic of the utility model is that also reduction voltage circuit, bridge rectifier, filter circuit, the voltage stabilizing circuit in the said circuit can process integrated circuit version.

The characteristic of the utility model is that also the reduction voltage circuit in the said circuit adopts resistance-capacitance depressurization or transformer step-down.

The characteristic of the utility model is that also said LED lamp string is formed by a plurality of LED lamp serial or parallel connections.

The beneficial effect of the utility model is: 1. efficient is high: because the spectrum of LED almost all concentrates on visible light frequency band, optical efficiency is far longer than incandescent lamp and is catching up with electricity-saving lamp and fluorescent lamp.2. the light quality is high: owing to do not have ultraviolet ray and infrared ray in the spectrum, so there is not heat, do not have radiation, can not bring burden to human eye, reading for a long time or work do not have the phenomenon that eyes are ached and swollen.3. color rendering is good: compare with fluorescent lamp, the color rendering index of high power LED desk lamp is high, usually about 80.Help reducing the degree of fatigue of human eye like this, vision protection is had very great help.4. maintenance cost is low: the LED life-span is long, and life-span luminous flux half-life surpassed more than 50,000 hours, and general normal use is more than 30 years.5. shock resistance and shock resistance are strong, do not have flimsy parts such as tungsten filament, glass bulb, and the possibility of improper " scrapping " is very little.6. volume is little: can make the small and exquisite exquisiteness of light fixture, be more suitable for different fields of employment.

The utility model adopts soft start in addition, and LED can send stable light like this, does not have stroboscopic phenomenon fully, makes vision feel very comfortable.Desk lamp is safe low-voltage input, the security incident of having avoided ordinary lamp and lantern to bring because of fault.
