Description
Technical field
The utility model relates to the lighting apparatus technical field, particularly a kind of energy-conservation eyeshield LED 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 its defect map is present: its brightness of LED lamp produces light and shade and changes along with the fluctuation of civil power, 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; And the drive circuit cost with voltage stabilizing function is high, is unfavorable for penetration and promotion.In addition, after mains switch broke off, when thunder and lightning touches electrical network or externally fed raises suddenly, even if when the outage of LED lamp is not used, drive circuit still might damage.
Therefore, design a kind of can be efficient, healthy, energy-conservation, the energy-conservation eyeshield LED lamp of no stroboscopic is problem of needing solution badly of electric field technical staff.
Summary of the invention
The purpose of the utility model provides a kind of environmental protection, health, energy-conservation, the energy-conservation eyeshield LED lamp that no stroboscopic, effectively prevention myopia, suitable student use.
The technical scheme of the utility model is:
A kind of energy-conservation eyeshield LED lamp comprises lamp bracket and control circuit, and it is characterized in that: said control circuit comprises power circuit, relay circuit and LED control circuit successively; 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, and 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 said relay circuit of the utility model 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.The LED control circuit adopts the soft starting circuit design in addition, 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 power circuit adopts DC power supply directly to supply power.Like this, DC power supply is stable, does not receive the ectocine ripple disable, does not have any twilight sunset, stroboscopic during the work of LED lamp.
The characteristic of the utility model is that also said power circuit adopts AC power, and the direct current that alternating current obtains behind reduction voltage circuit, rectification circuit, filter circuit, voltage stabilizing circuit is the control circuit power supply.Further, reduction voltage circuit adopts resistance-capacitance depressurization or transformer step-down.Reduction voltage circuit in the said circuit, bridge rectifier, filter circuit, voltage stabilizing circuit can be processed integrated circuit version.
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.A plurality of LED lamp strings can be arranged in arbitrary graphic pattern according to hobby, strengthen the aesthetic feeling of product.
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.
