With the array LED lighting device, heat produced by the light emission of the LEDs can be effectively dissipated, and no heavy influence on the integrated light emitting effect of the LED lighting device when some LEDs are damaged can be also guaranteed.
Description
Technical field
The utility model relates to the technical field of LED lighting, the array-type LED lighting device that particularly a kind of high efficiency and heat radiation and service life increase.
Background technology
LED (Light-Emitting-Diode, light emitting diode) is a kind of semiconductor that can electric energy be converted into luminous energy, and it has changed the luminous and luminous principle of electricity-saving lamp tricolor powder of incandescent lamp tungsten filament, and adopts electroluminescence.
The characteristics of LED are very obvious, and its life-span is long, light efficiency is high, radiationless and low-power consumption.The spectrum of LED almost all concentrates on visible light frequency band, and its luminous efficiency can surpass 150lm/W.LED and ordinary incandescent lamp, spiral energy-saving lamp and T5 three-color fluorescent lamp are compared, and the result shows: the light efficiency of ordinary incandescent lamp is 12lm/W, and the life-span was less than 2000 hours; The light efficiency of spiral energy-saving lamp is 60lm/W; Life-span, the T5 fluorescent lamp then was 961m/W less than 8000 hours, and the life-span is approximately 10000 hours; Can surpass 150lm/W in theory and diameter is 5 millimeters a white light LEDs light efficiency, the life-span can be greater than 100000 hours.Following LED life-span upper limit is with infinity.
Yet; The operation principle of LED lamp makes and becomes very outstanding in high-power LED illumination industry heat dissipation problem; Many LED illumination schemes are paid little attention to heat radiation; Or technical merit is limited, so the high-powered LED lamp ubiquity of volume production is nothing like theoretical value actual life at present, cost performance is lower than the awkward situation of conventional lamp.
The utility model content
In view of the above-mentioned deficiency of prior art, the utility model provides the array-type LED lighting device that increases in a kind of high efficiency and heat radiation and service life.
An aspect according to the utility model provides a kind of array-type LED lighting device, comprising: a plurality of LED lighting units with array format, and power distribution circuit plate; Said four LED lighting units are arranged on the said power distribution circuit plate; And by this power distribution circuit plate power supply; It is characterized in that: each comprises the LED of predetermined number said a plurality of LED lighting units; And said a plurality of LED lighting unit predetermined distance that is isolated from each other, thereby between two adjacent LED lighting units, form heat dissipation channel.
According to another aspect of the utility model, in said array-type LED lighting device, in the heat dissipation channel between two adjacent LED lighting units, be formed with a plurality of louvres.
The array-type LED illuminator structure of the utility model is simple, and reliability is high, can not only effectively distribute the heat by the luminous generation of LED, can also guarantee when some LED is damaged, and can seriously not influence the whole illumination effect of LED lighting device.
Description of drawings
Fig. 1 is the structural representation of the array-type LED lighting device of the utility model; And
Fig. 2 is the sketch map of the concrete structure of the LED lighting unit in the array-type LED lighting device of the utility model.
The specific embodiment
Below, with the embodiment of accompanying drawings the utility model.
Fig. 1 is the structural representation of the array-type LED lighting device of the utility model.As shown in Figure 1, this array-type LED lighting device 1 comprises four LED lighting units 2 with array format, and power distribution circuit plate (not shown).These four LED lighting units 2 are arranged on this power distribution circuit plate, and by this power distribution circuit plate power supply.Each comprises the LED of predetermined number this four LED lighting units 2, and the predetermined distance that is isolated from each other, thereby between two adjacent LED lighting units 2, forms heat dissipation channel.In addition, in the heat dissipation channel between two adjacent LED lighting units 2, also be formed with a plurality of louvres 3.
Through between two adjacent LED lighting units 2, heat dissipation channel being set, the heat that makes each LED lighting unit send can promptly distribute.In addition, a plurality of louvres 3 that in heat dissipation channel, are provided with can further improve cross-ventilation, further help distributing of heat.
As shown in Figure 2, show the concrete structure of said LED lighting unit 2.Shown in Figure 2 like this, in LED lighting unit 2, be furnished with a plurality of LED (in Fig. 2,5*4 totally 20 LED being shown).These LED all are connected in series, but are divided into a plurality of groups, and for being connected in parallel, and each LED among organizing is for being connected in series between each group.And each each LED that organizes among the LED is not adjacent to each other.
For example, in Fig. 2, with 4 the sign LED (being shown black) be first group of LED, and 5 the sign LED (being shown white) be second group of LED.The connection that is one another in series of 10 LED in first group, and the connection that is one another in series of 10 LED in second group; But between first group of LED and the second group of LED for being connected in parallel.
The advantage of this set mode is: if some LED break down, then only this fault LED place group can not be normally luminous, and other groups LED still can be normally luminous.Though this makes that this LED lighting unit illumination effect is influenced, on the whole still can luminous work.In addition, each group each LED among LED is set to not adjacent to each other, can also avoid the LED lighting unit to appear at the tangible illumination defective on a certain zone or a certain line, has guaranteed the illuminating effect of this fault LED lighting unit on the whole.
Utilize the array-type LED lighting device of the utility model, can not only effectively distribute heat, can also guarantee when some LED is damaged, can seriously not influence the whole illumination effect of LED lighting device by the luminous generation of LED.
It will be understood by those skilled in the art that above-mentioned explanation and instance only are exemplary, and be not the scope that is used to limit the utility model.Under the degree of the scope that does not exceed the utility model that limits like claims, can carry out various improvement to the utility model.
For example, the number of said LED lighting unit is not restricted to 4, but can be set to arbitrary number according to actual needs, as long as they are set up the form of array.The shape of said LED lighting unit is not restricted to rectangle, but can be circular, ellipse, polygon or the like.And the number of the LED in the said LED lighting unit also is not restricted to 20, and the LED group also is not limited to two.
