Abstract

The utility model discloses a split-type two-end-installation LED drive power. The LED drive power comprises an input EMC filter circuit and an input rectifier element of a control circuit both positioned on one end of the LED drive or control power; also comprises an output filter portion, a switch MOSfet, a control IC and a transformer all positioned on the other end of the LED drive or control power; middle V+ are connected through wires; and LED- and LED + are connected on a lamp board or a lamp bar to realize electric connector. Heat value of the drive power and heat value of a light source are not affected by each other, so service life of the light source and the power is prolonged; simultaneously the LED drive power can be used as an internal or external power to satisfy client demands; and as the internal power, wires of the LED drive power can be prepared to be long or short, so the internal power can be applied in lamps with different lengths. The split-type two-end-installation LED drive power is low in cost, easy in installation, and wide in application scope.

Description

The LED driving power is installed at a kind of detachable two

Technical field

The utility model relates to LED and drives the field, relates in particular to the structure that LED drove or controlled power supply.

Technical background

The application of LED illumination has launched one upsurge in the whole world, as the new type light source of long-life, low-power consumption, high light efficiency, environmental protection, the stability of its driving power, reliability and life requirements are harsh especially.And the factor that affects driving power reliability, stability and life-span mainly is exactly temperature.For conventional LED fluorescent lamp built-in power, driving power is placed on LED lamp plate back, and LED driving power and light source caloric value interact, and have a strong impact on the life-span; Driving power is placed on LED lamp plate back so that the light source luminescent curved surface reduces simultaneously, affects lighting angle.Driving power is done the as a whole lamp plate back that is placed on and has been accounted for the very large space of light fixture, causes heat to be difficult to distribute, and internal temperature is too high.

The utility model content

For addressing the above problem, the utility model discloses a kind of detachable two the LED driving power is installed, it is characterized in that, comprise input EMC filter circuit, input rectifying device, output filtering part, switch MOS fet, control IC and the transformer of control circuit.

An end of LED control power supply under the input EMC filter circuit of control circuit, input rectifying device, output filtering partly are positioned at.

The other end of LED control power supply under switch MOS fet, control IC, transformer are positioned at.

Detachable two is installed the LED driving power and is broken rear two ends into two with one's hands and be connected on the LED lamp by wire as mentioned above, and wire is changeable, is applicable to the fluorescent tube of different length.

The middle V+ that LED driving power two ends are installed at above-mentioned detachable two connects by wire, and LED-and LED+ are connected on lamp plate or the lamp bar.

The beneficial effect that the utility model embodies is:

(1) the utility model carries out Structure Improvement on the basis of in the past built-in daylight lamp power source, can effectively increase the luminous curved surface of LED lamp pearl, improve the radiating effect that LED drove or controlled power supply and LED, thereby the cross influence of the heat generation that solution LED driving power and light source send, enlarge their radiating surface, therefore reduce the temperature of LED driving power and light source, prolong the life-span of driving and lamp; The utility model production test is convenient simultaneously.

(2) the utility model both can also can be used as built-in driving as external driving, and easy for installation, cost is low, has not only satisfied client's demand, and the disjunction two ends that are installed on light fixture have a kind of aesthetic feeling of symmetry.

(3) to break into two with one's hands be two to have no progeny to the utility model, connects light fixture by wire, and wire is changeable, can be used for the light fixture of different length, and is therefore convenient and practical.

Description of drawings

Fig. 1 is overall structure schematic diagram of the present utility model.

Fig. 2 is that the utility model breaks into two with one's hands is structural representation behind two ends.

Fig. 3 is stereogram of the present utility model.

Embodiment

In order to more fully understand the utility model technology contents, below in conjunction with specific embodiment the technical solution of the utility model is further introduced and explanation:

Fig. 1 is overall structure schematic diagram of the present utility model, and the utility model comprises input rectifying device, output filtering part, PCB stamp hole, switch MOS fet, control IC and the transformer of input EMC filter circuit, control circuit.

Fig. 2 is that the utility model breaks into two with one's hands is an overall schematic that is connected by wire after two parts, wherein control circuit input rectifying device, input EMC filter circuit, output filtering part, be positioned at the left end of PCB stamp hole, switch MOS fet, control IC and transformer are positioned at its right-hand member, two parts after breaking into two with one's hands are connected by wire, V+ connects by wire in the middle of it, and LED-and LED+ are connected to and realize electric company on lamp plate or the lamp bar; Wherein wire is changeable, is applicable to the LED fluorescent tube of different length.

LED drives or controls power supply in production survey formula, connect with the fluting of being connected by the PCB stamp hole when aging, when producing, guarantee like this as whole, if the client is used for external then can be used as a single unit system in shell, then be connected with the LED lamp by wire, this has just been avoided LED to drive the situation that is positioned over the lamp plate back and causes the heat intersection to be difficult to distribute; If be used for built-inly then can breaking into two with one's hands from the centre when client assembles, realize separating, then in the middle of V+ connect by wire, LED-and LED+ are connected to and realize electrical connection on lamp plate or the lamp bar.Therefore, can reduce and drive the space that takies light fixture, then can well dispel the heat, thereby effectively increase the luminous curved surface of LED, improve LED and drive or control power supply and LED radiating effect, LED lamp and LED drive and have reached good configuration like this, thereby have improved its radiating effect, and then have prolonged the life-span of LED lamp and LED driving.Simultaneously because wire is changeable, so the client can be installed in it fluorescent tube of different length when being used for built-in power, and this has just satisfied client's demand.

Above content be in conjunction with concrete optimal technical scheme to explanation of the present utility model, can not assert that implementation of the present utility model is confined to these explanations.Concerning the utility model person of an ordinary skill in the technical field, can also make without departing from the concept of the premise utility some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
