Abstract
The utility model relates to the field of light-emitting diode (LED) illumination, in particular to an LED lamp. The LED lamp comprises a lampshade and a lamp cap. A lamp panel is arranged in the lampshade, two or more than two lamp beads are arranged on the lamp panel, an alternating current-direct current (AC-DC) switch constant current power supply is arranged between the lamp panel and the lampshade, the output end of the AC-DC switch constant current power supply is connected with one end of a power line, and the other end of the power line is connected with a contact of the lamp cap. When the novel LED lamp is used, due to the fact that the AC-DC switch constant current power supply is integrated in the lampshade, an alternating current can be converted into a constant current direct current which is used for the LED lamp, so that the LED lamp can be connected to a normal lamp base to be used directly, and the LED lamp is enabled to have the advantages that applicability is improved, cost is saved, and energy is saved.
Description
Technical field
The utility model relates to the LED lighting field, is specifically related to a kind of LED lamp.
Background technology
Energy savings is the large theme that society faces, and in the face of the swift and violent increase of commercial power and the urgent need of people's household electricity, at present, supply of electric power is very nervous, and noisy severe power shortage often.Seek new product, alleviate the electricity consumption imbalance between supply and demand, this is that pendulum is in a top priority of governments at all levels and relevant department.Fluorescent lamp replaces bulb, has saved the part electric energy, but is badly in need of in the face of growing electricity consumption, still can not alleviate the imbalance between supply and demand of electricity consumption, must seek new new energy saving product.The LED light fixture has power savings advantages, but existing LED lamp needs direct current supply, also there is no the structure of AC-DC power supply and LED lamp integral type on market, and therefore comparatively inconvenience of existing LED lamp practicality needs special distribution source.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of LED lamp and solves the other outfit of LED need power supply in prior art, and the not good problem of applicability.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of LED, comprise lampshade and lamp holder, be provided with lamp plate in described lampshade, be provided with two or more LED lamp pearls on described lamp plate, also be provided with AC-DC switch constant-current supply between described lamp plate and lampshade, one end of the output connecting power line of described AC-DC switch constant-current supply, the other end of described power line is connected with the lamp holder upper contact.
The beneficial effects of the utility model are: using the utility model LED lamp, because integrated AC-DC Switching Power Supply in lampshade can be converted into alternating current constant current direct current for LED, therefore the LED lamp is received on common lamp socket and is directly used, make the LED light fixture have applicability to strengthen, save cost and energy-conservation advantage.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described lamp holder comprises screw socket and bayonet socket.
Adopt the beneficial effect of above-mentioned further scheme to be: identical with the connector of existing light fixture, can directly replace use, further saved alternative costs.
Further, be provided with constant-current circuit and ac/ac power converter in described AC-DC switch constant-current supply.
Adopt the beneficial effect of above-mentioned further scheme to be: described ac/ac power converter and constant-current circuit collocation are used, ac/ac power converter is converted to direct current with alternating current, constant-current circuit output fixed current direct current, can make LED adapt to the alternating current of 110V, 220V and 380V, applicability further strengthens.
