Technical field
The utility model embodiment relates to the lighting technology, relates in particular to a kind of modular light-emitting diode (Light Emitting Diode; Hereinafter to be referred as: LED) light fixture.
Background technology
The appearance of semiconductor lighting device-led light source makes traditional lighting engineering obtain leap again.Led light source is with its energy-saving and environmental protection and characteristic such as long-acting, and progressively substituting with the incandescent lamp is the traditional lighting light source of representative, and this trend spreads in the world fast.
Yet owing to be subjected to the restriction of material behavior and manufacturing process technology, still there are some defectives not fully up to expectations in present widely used led light source (or claiming the LED device), and it is still lower mainly to show as electro-optical efficiency.Calculate according to theory, a LED device is in normal environment for use, and its useful life should be more than 50,000 hours, and still because electro-optical efficiency only has about 30% usually, therefore, most of electric energy all is converted to heat.These heats raise the P-N junction temperature of LED device, and after the P-N junction temperature surpasses certain numerical value, the luminous flux that the LED device is sent are significantly reduced.The alleged light decay phenomenon of industry also just occurs, after light decay drops to certain proportion, then declared the life termination of this LED device.Therefore, the heat that produces when effectively the LED device being worked sheds fast, make the P-N junction temperature maintain a lower level, be to guarantee that the LED device is normal, the key issue of long-acting use, only address this problem, actual life of LED device is reached or, economic illumination can be when realizing the energy-saving and environmental protection illumination, realized near time limit of theoretical service life.
For this reason, emerged the technical scheme of a large amount of solution LED device heat dissipation problems both at home and abroad, in these technical schemes, the overwhelming majority is to adopt the aluminium alloy manufacturing heat radiator dedicated, realizes heat radiation.
Fig. 1 is the structural representation of existing a kind of strip light fixture of using always, and this light fixture comprises base 110 and a plurality of LED device 120 that is used for the double as radiator.Base 110 adopts the machine-shaping of aluminium alloy stretching mode usually, and many parallel heat sink strips 111 are formed at its top, also can be referred to as radiating fin.120 distributions of a plurality of LED devices are arranged on the installed surface 113 of base 110 bottoms.The dual-side of installed surface 113 convexes with the frame that inner surface is offered chute 112 downwards.Plate lampshade can be installed in base 110 belows by chute 112.When the work of this light fixture, the heat that LED device 120 produces conducts to heat sink strip 111 by installed surface 113, by heat sink strip 111 heat is shed again, realizes reducing the purpose of the P-N junction temperature of LED device 120.
Structurally still there are some technological deficiencies in above-mentioned existing technical scheme, and it is still lower that it shows as heat dissipation, and Fig. 2 is the structure enlarged diagram of many heat sink strips 111 in the light fixture shown in Figure 1.
As shown in Figure 2, according to gas warm-up movement principle as can be known: temperature raises after being in the air on heat sink strip 111 surfaces and heat sink strip 111 and producing heat exchanges, produce motion (shown in arrow line c among Fig. 2) upwards, the air of be not heated on every side, temperature is relatively low then moves to heat sink strip 111 directions under the effect of negative pressure, forms ftercompction air-flow (shown in arrow line d among Fig. 2).Because 111 pairs of heat-dissipating spaces of heat sink strip of the installed surface 113 and the left and right sides have formed three blocking, cause the outside cold airflow (shown in arrow line e among Fig. 2) that moves upward naturally can not or to be difficult for entering in the heat-dissipating space.The air that is in the heat-dissipating space then forms eddy current in above-mentioned shuttling movement, this eddy current constantly is subjected to the heating of heat sink strip 111, temperature raises gradually, cause and heat sink strip 111 between the temperature difference reduce gradually, cause the radiating efficiency of heat sink strip 111 significantly to reduce.

Have again, present employed LED light fixture all is to adopt to design specific fitting structure separately according to particular demands usually, in this design process owing to need to consider multiple factors such as light efficiency, the configuration of light shape, radiating effect and application scenario, so design process is very long, inefficiency and often can not practical requirement.
Above-mentioned these problems all are to hinder that the LED lighting popularizes rapidly, as needing to demand solution urgently major issue at present.
