Abstract
The utility model relates to an LED (light-emitting diode) lamp, particularly an LED (light-emitting diode) lamp of an external direct current power supply system. The LED lamp of the external direct current power supply system comprises an LED lamp and a drive unit for driving the LED lamp. The LED lamp is characterized by also comprising a direct current power supply system arranged on the external part of the LED lamp for converting alternating current power supply into direct current power supply. Compared with the prior art, the direct current power supply system is arranged on the external part of the LED lamp without directly acting on the LED lamp body, so that the radiating property of the LED lamp is enhanced, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of LED light fixture, specifically a kind of LED light fixture of external DC power-supply system.
Background technology
The major function of LED lamp power is to convert alternating voltage into constant current output; But present AC-DC conversion system generally is assemblied in the inside of LED lamp outer casing; The heating of power supply has increased extra burden for again the radiator structure of LED light fixture like this; In order to strengthen the heat dispersion of LED lamp, a kind of new LED light fixture need be provided.
Summary of the invention
The utility model is in order to overcome the deficiency of prior art, and a kind of LED light fixture of simple in structure, perfect heat-dissipating is provided.
To achieve these goals; The utility model has designed a kind of LED light fixture of external DC power-supply system; Comprise the LED lamp; And the driver element that is used for the driving LED lamp, it is characterized in that: comprise that also an outside that is arranged on the LED lamp converts AC power to the DC power-supply system of dc source.
Said LED lamp, driver element and DC power-supply system connect through the mode of series connection successively.
Said LED lamp is at least more than two, and connects corresponding driving unit separately respectively, and every group of driver element is connected on the DC power-supply system through the mode of parallel connection.
The utility model is compared with prior art, and DC power-supply system is arranged on the outside of LED lamp, does not directly act on LED lamp itself, the heat dispersion of LED lamp is strengthened greatly, and improved service life.
Description of drawings
Fig. 1 is the series connection sketch map of the utility model LED lamp.
Fig. 2 is the parallelly connected sketch map of the utility model LED lamp.
Referring to Fig. 1 and Fig. 2,1 is the LED lamp; 2 is driver element; 3 is DC power-supply system.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, LED lamp 1, driver element 2 and DC power-supply system 3 connect through the mode of series connection successively.For the lower occasion of light source requirements, this connection French is not only simple, and practical.
As shown in Figure 2, LED lamp 1 is a plurality of, and connects corresponding driving unit 2 separately respectively, and every group of driver element 2 is connected on the powerful DC power-supply system 3 through the mode of parallel connection.For the higher occasion of light source requirements, the LED lamp can connect through the mode of parallel connection, makes its luminous brightness become big, applicable to industries such as some industrial and mineral, collieries.
Compare with prior art, DC power-supply system is arranged on the outside of LED lamp, do not directly act on LED lamp itself, the heat dispersion of LED lamp is strengthened greatly, thereby improved the service life of LED lamp.
