Description

A kind of electricity-saving lamp
Technical field
The utility model relates to a kind of light fixture, is the high electricity-saving lamp of a kind of energy-saving efficiency specifically.
Background technology
At present, the light fixture of life illumination is based on incandescent lamp, fluorescent lamp and rare-earth trichromatic fluorescent lamp.The usable floor area in general resident room is approximately tens square metres, under the situation that satisfies the brightness of illumination requirement, if use incandescent lamp, then its power should be about 60W, if use fluorescent lamp, then its power should be about 40W, if use the rare-earth trichromatic fluorescent lamp, then its power should just can meet the demands more than 20W, and its weak point is: 1, the incandescent lamp electro-optical efficiency is poor, does not economize on electricity; 2, fluorescent lamp has power savings, but the life-span is shorter; 3, rare-earth trichromatic fluorescent lamp efficient height, but price is expensive, and the life-span is also restricted, in today of energy growing tension, develops a kind of energy-efficient lamp, seems extremely important.
The utility model content
The technical problems to be solved in the utility model is to provide the electricity-saving lamp that a kind of electro-optical efficiency height, operating cost are low, the life-span is long at above-mentioned deficiency.
For solving the problems of the technologies described above, this electricity-saving lamp comprises lamp socket, is connected the lampshade on the lamp socket, and its design feature is: be provided with a plurality of light emitting diodes that are installed on the lamp socket in lampshade, also be provided with power supply changeover device on the lamp socket, power supply changeover device is electrically connected with light emitting diode.
Power supply changeover device is converted to the DC voltage that suitable LED power source requires with the electric main of 220V, and this DC voltage is added to the two ends of light emitting diode, and to the light emitting diode power supply, light emitting diode just can give out great brilliancy; The quantity of light emitting diode is many more, and its brightness is high more, and power consumption also increases relatively; Since adopt light emitting diode as the electric light conversion element, the electro-optical efficiency height, and energy-saving effect is apparent, this electricity-saving lamp of a 5W, be equivalent to the brightness of 40W fluorescent lamp, also save about 78%, can be country and save a large amount of electric energy than present rare-earth trichromatic fluorescent lamp.Use light emitting diode as light-emitting component, long service life can reach more than 50,000 hours; How much the cost of a light emitting diode is about even several sharing money, more much higher than the cost performance of fluorescent lamp and rare-earth trichromatic fluorescent lamp.
As improvement, adjustable for the output voltage stabilization that makes power supply changeover device, power supply changeover device adopts three-terminal voltage regulator, and three-terminal voltage regulator adopts the LM317 chip.When needs improve the supply voltage of light emitting diode, can adjust the adjustment resistance of LM317, the output voltage of LM317 is suitably heightened, perhaps when the quantity of light emitting diode increases, also need to heighten the output voltage of LM317, otherwise, the output voltage of LM317 is turned down.
In sum, adopted the electricity-saving lamp of this structure, cost is low, the life-span is long, electro-optical efficiency is high, is the desirable substitute products of present lighting, is the environmental protection electric light source.
