Description
[technical field]
The present invention relates to a kind of self-cooling LED lamp pearl and illuminating module thereof, particularly a kind of have excellent heat dispersion performance and self-cooling LED lamp pearl and an illuminating module thereof easy for installation.
[background technology]
In traditional lighting engineering, use osram lamp more, because power consumption and volume are big, luminous efficiency is low, the life-span is short, and more and more can not adapt to the needs of modern society.Along with development of semiconductor, power consumption and volume are little, and luminous efficiency is high, and the life-span, the long application of LED in electric light source technology more and more received people's attention.
Along with development of technology, the application of light emitting diode (LIGHT EMITINGDIODE is called for short LED) is increasingly extensive, and especially the power of LED is updated raising, and LED is shown to the field of lighting source infiltration and development by signal gradually.Yet the popularization of great power LED, facing maximum problem is that luminous total brightness is low.For improving luminous total brightness, generally take to improve single LEDs brightness, and with many packaged LED lamp pearls, the way of taking connection in series-parallel to gather together.No matter improve the brightness of single chips, or the method that gathers together of connection in series-parallel, all to add high-power, the generation that all can sharply strengthen heat.The general single power of LED lamp pearl all is smaller, and brightness is not enough, and in order to improve brightness, people often use a plurality of LED lamp pearl combinations as a light source, be fixed on simultaneously on a circuit board and the radiator.Brightness of LED lamp pearl and life-span and its operating temperature have certain relation, and the LED radiating effect is good more, and operating temperature is low more, and brightness is high more, and the life-span is long more.Along with the LED improvement of Manufacturing Technology; What now single led power can have been done is increasing, and during a shared fin, radiating effect is poor; Particularly when any large-power LED light bead is overheated; This heat can improve the temperature of monoblock fin, thereby has lowered the function of fin heat radiation, even might cause the too high even breaking-up of temperature of other lamp pearls.
LED only has the electric energy about 35% to convert light ray radiation to come out at present, and all the other electricity of about 65% have been transformed into heat.Low-power LED heat production total amount is few, and heating problem is not outstanding, and high-power illumination is used LED; Its power is tens of original little LED; Hundred times, heating problem have once become influences one of the most critical of LED life-span and luminous efficiency factor, and becomes the maximum bottleneck problem of obstruction illumination popularization.Therefore, how to solve the major issue that heat dissipation problem becomes the LED industry development.In addition, because existing LED optical texture all is that the LED module cooperates a radiator, be area and the weight that increases radiator when guaranteeing radiating effect thereby cause the designer, so it is little to make product satisfy volume, demand in light weight, easy to assembly.
