Description
One. technical field
The utility model relates to a kind of light fixture, especially a kind of dual power supply energy-saving desk lamp.
Two. background technology
Existing in the market energy-saving desk lamp mainly contains rechargeable and direct insertion two kinds: (one) rechargeable desk lamp is AC energy to be converted to be converted into dc source again after chemical energy is stored in battery, it has the following disadvantages: 1. desk lamp power is too small, illumination zone is limited, can't satisfy the study and work needs; 2. battery belongs to the consume product, and service life is limited, and is difficult for changing.(2) direct insertion then is directly will to be operated on the fluorescent tube after the alternating current step-down, operating current or alternating current, and general supporting neon fluorescent tube, it has the following disadvantages: 1. service life is not as good as the most energy-conservation current LED; 2. the lamp tube shapes of making desk lamp differs, and changes difficulty of matching ratio; 3. the outage use of the time can't meeting an urgent need.
For addressing the above problem, the someone releases USB desk lamp and telephone wire desk lamp, and it also has the following disadvantages: 1. structure is single; 2. function singleness; 3. use face is limited, can't large-scale popularization.
Three. summary of the invention
Task of the present utility model provides a kind of dual power supply energy-saving desk lamp, it had both used the rechargeable type desk lamp under current failure emergency the function and the illuminating effect of direct insertion desk lamp optimize and combine, the use of under powering-off state, meeting an urgent need, having cancelled battery again simultaneously reduces cost, illumination reaches the effect of direct insertion desk lamp, longer service life, energy-saving effect is more excellent, and cost is lower.
For finishing this task, the utility model carries out in the following way:
It comprises: lamp holder, flexible support bar, ac plug and electric wire, it also comprises: electric capacity, resistance, whole ripple electric bridge, light emitting diode, telephone line joint, be connected a current limliting reduction voltage circuit by electric capacity, resistance parallel connection between ac plug one end and whole ripple electric bridge one joint, the ac plug other end connects whole another joint of ripple electric bridge; Two electric capacity in parallel constitute filter circuit, two groups of light emitting diodes in parallel constitute the lamp holder light source, one end of filter circuit and light source parallel connection is connected the first end of telephone line and joint of whole ripple electric bridge respectively, and the other end of filter circuit and light source parallel connection is connected the telephone line joint other end and whole another joint of ripple electric bridge respectively; The flexible support bar that connects lamp holder can arbitrarily angled rotoflector; Described ac plug uses when electricity is arranged, and telephone line joint uses when having a power failure, and can both make lamp holder luminous.
The utility model is because be provided with resistance-capacitance depressurization rectification circuit and light emitting diode, and without battery, dc source is stable so light-emitting diodes is in control, low, the long service life of cost simple in structure; Also be connected with telephone line joint because light emitting diode constitutes the lamp holder light source simultaneously, use so can also when outage, meet an urgent need; In addition owing to adopting the flexible support bar, so lamp holder can arbitrarily angled rotoflector.
