The specific embodiment

Below in conjunction with specific embodiment, further illustrate the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.The experimental technique of unreceipted actual conditions in the following example, usually according to normal condition, or the condition of advising according to manufacturer.Ratio and percentage are based on weight, unless stated otherwise.

The specific embodiment as shown in Figure 1, the novel little power consumption desk lamp of this usefulness comprises lamp bracket 1, light source 3, described lamp bracket 1 comprises lamp socket 4 and lampshade 5, described lamp socket one controller for electric consumption 6, controller for electric consumption 6 is connected with power switch respectively.Controller for electric consumption 6 comprises transformer 7, power switch 2 and LED4 or the lampshade 5 interior fixed current limiter 10 that are electrically connected successively.Described rectifier 8 has adopted electron rectifier, and power switch 2 and three led light source 3 electric rectification devices 8, wave filter 9 and wave filter 9 current limiters 10 adopt the voltage-stabiliser tube current limliting, certainly, also can use the resistance current limliting.Described timing means 11 comprises timer 12 and control chip 13, is connected with power switch 2, electric light source electricity 3.Inner cover 11 surfaces are minute surfaces, and this will effectively improve the reflecting effect of light.Adopt capacitive filter, described lampshade 5 certainly, what 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 exchanges and converts direct current to, through capacitor filtering, be transported to each LED with little electric current (about 200mA) than voltage with low current limliting and with the direct current of low-voltage.

Scope of the present utility model is not subjected to the restriction of described specific embodiments, and described embodiment is only desired also to comprise the method and the component of functional equivalent in the utility model scope as the single example of illustrating the utility model various aspects.In fact, except content as herein described, those skilled in the art can easily grasp multiple improvement of the present utility model with reference to above description and accompanying drawing.Described improvement also falls within the scope of appended claims.
