Abstract
The utility model discloses a little consumption desk lamp, it includes lighting fixture, switch and 1 or a plurality of LED light source, and the lighting fixture includes lamp stand and lamp shade, a lamp stand or a lamp shade internal fixation one respectively with the electric control unit that switch and LED lamp electricity are connected. The electric control device comprises a transformer, a rectifier, a filter and a current limiter which are connected in sequence. Because the utility model discloses a desk lamp light source has adopted LED, makes the desk lamp realize the micro-power consumption to reach energy-conserving purpose, on the other hand makes the structure of desk lamp compacter because the LED light source is small with ordinary light source.
Description
Technical field
The utility model relates to a kind of lighting device, especially a kind of energy-saving desk lamp.
Background technology
At present, the common desk lamp in market generally uses Halogen lamp LED, incandescent lamp or fluorescent lamp as light source, but Halogen lamp LED, incandescent lamp ubiquity caloric value are big, the low deficiency that waits of light efficiency, the luminous efficiency of desk lamp is low on the one hand, on the other hand because a large amount of heat release makes light fixture aging easily; And with the light source of fluorescent lamp as desk lamp, existing luminous efficiency does not have and significantly improves, and makes deficiencies such as desk lamp volume increase.But people are to improving the light efficiency of desk lamp, energy efficient has also been done some explorations, a kind of amplification energy-saving desk lamp (patent No.: 99208219 is disclosed in March, 2000 as State Intellectual Property Office, publication number: 2370263), bibliographical information this desk lamp constitute by lamp holder, support bar and base, be covered with transparent parabolic shape lampshade above the lamp holder, power saving fluorescent lamps is housed in the lamp holder, be provided with the primary and secondary magnifying glass in the middle of the power saving fluorescent lamps, amplifying energy-saving desk lamp can brightly shine, can amplify lighting object again, thus energy efficient.But this kind desk lamp energy consumption still need be imported power saving fluorescent lamps power, can't make desk lamp realize little power consumption.
Summary of the invention
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of energy-saving desk lamp of little power consumption.
For achieving the above object, the technical scheme that little power consumption desk lamp of the present utility model adopts is: a kind of little power consumption desk lamp, and it comprises lamp bracket, power switch and electric light source, described lamp bracket comprises lamp socket) and lampshade, described electric light source LED lamp; Fix a controller for electric consumption in lamp bracket, described control device is electrically connected with power switch, electric light source respectively.
Described controller for electric consumption comprises inferior to the transformer, rectifier, wave filter and the current limiter that are electrically connected.
The aforementioned electric light source is one or more LED lamps
Because the light source of little power consumption desk lamp of the present utility model has adopted one or more LED, and the luminous efficiency of desk lamp is significantly improved, consumed power reduces, and really makes desk lamp realize little power consumption, and the consumed power of whole desk lamp is generally less than 1W.And the volume of LED is little, makes the structure of desk lamp compact more.
Description of drawings
Fig. 1 is the structural representation of the little rate consumption of the utility model desk lamp, shows the overall structure of desk lamp.
The specific embodiment
As shown in Figure 1, the novel little power consumption desk lamp of this usefulness comprises lamp bracket 1, power switch 2 and led light source 3, described lamp bracket 1 comprises lamp socket 4 and lampshade 5, fixes a controller for electric consumption 6 in described lamp socket 4 or the lampshade 5, and controller for electric consumption 6 is electrically connected with power switch 2 and three led light sources 3 respectively.Controller for electric consumption 6 comprises transformer 7, rectifier 8, wave filter 9 and the current limiter 10 that is electrically connected successively.Described rectifier 8 has adopted electron rectifier, and wave filter 9 adopts capacitive filter, and current limiter 10 adopts the voltage-stabiliser tube current limliting, certainly, also can use the resistance current limliting.Inner cover 11 surfaces of described lampshade 5 are minute surfaces, and this will effectively improve the reflecting effect of light.
What certainly, require LED according to the difference of desk lamp can be 1,2 or more a plurality of.
The utility model is worked in the following manner: after desk lamp is opened switch, the alternating current of 220V or 110V is become low-voltage (about 4.5V) alternating current through transformer 7 transformations, electron rectifier converts the interchange of low-voltage to direct current, through capacitor filtering, current limliting and the direct current of low-voltage is transported to each LED with less current (about 200mA).
