Description
Technical field
This practicality invention relates to a kind of LED lamp and light fixture thereof, is specifically related to have the high-powered LED lamp unit module of high heat dispersion and the Modularized high power LED lamp tool of composition thereof.
Background technology
LED (light emitting diode) is that a kind of electric current that utilizes forward is passed to coupling place of emitting semiconductor p-n junction, impel electronics in the P district with hole-recombination, and the form of unnecessary energy with light and heat discharged, thereby is light and hot light source with electric energy conversion.It has use low-tension supply, power consumption less, applicability is strong, stability is high, the response time is short, environmentally safe, multicolor luminous, long service life and the plurality of advantages such as sturdy and durable, it can use 100,000 hours continuously, life-span is than long 100 times of ordinary incandescent lamp bubble, therefore, it has become the developing direction of following illuminating product, the speed of LED replacement traditional lighting light source has been accelerated in the particularly appearance of the logical LED lamp of high-power high light.
The subject matter of high-power LED lamp design at present is how to realize safety between electricity, light, hot three, stable, high efficiency conversion.Aspect electricity, the principle of luminosity of LED requires " crossing current drives ", and namely stable electric current is the key of electricity aspect; The optics aspect, except the basic problems such as rational luminous intensity distribution, colour temperature and colour rendering, also require higher light extraction efficiency, namely arrive from chip the luminous energy that loses the irradiated area the smaller the better, at present because the LED lamp once encapsulates, secondary lens is added the light fixture outer cover, generally need to be through three layers of PC or acrylic material, the light loss rate is generally between 20～30%; The calorifics aspect, the junction temperature of controlling LED is key issue in order to extend its service life.Because the photo-thermal transformation efficiency of present LED lamp is approximately 3 to 7, the most of electric energy that is to say the LED lamp is converted into heat energy and distributes, if can not effectively dissipate these heats, it is very obvious that thing followed fuel factor will become: 1. junction temperature raises, directly reduce the photon that chip penetrates, make and get the optical efficiency reduction; 2. the rising of temperature can make the emission spectrum generation red shift of chip, and the colour temperature Quality Down is especially even more serious to excite the white light LED part of yellow fluorescent powder based on blue-ray LED, and wherein the conversion efficiency of fluorescent material also can be along with temperature raises and reduces.Therefore the various fuel factors that produce due to the temperature rising can badly influence service life and the reliability of LED device.The key issue that makes the junction temperature of controlling LED become stability and increase the service life.In sum, in heat, light, electric three fields, stable electric current relatively easily reaches at present, and topmost problem is to dispel the heat and two aspects of luminous intensity distribution.Heat radiation has determined the life-span length of LED, and luminous intensity distribution has determined whether the usability of LED is more excellent than other light source.Many kind designs are arranged now, all made different trials in the design of the selection of encapsulating structure, light-configuration mode, heat sink material, radiator structure etc., but be take circuit board as the cross section basically, and at the back side of circuit board, radiator structure be set and dispel the heat.shown in Figure 1 is a kind of typical structure of existing high-powered LED lamp cell cube, it is by hemispherical lens 1, chip 2, heat sink 3, circuit board 4, heat-sink unit and electrode, gold thread once encapsulates and forms, the chip 2 that its core is comprised of p-type semiconductor and N-shaped semiconductor, heat-sink unit adopts fin 5, chip 2 welds on the heat sink end face that h is fixed on patty by eutectic, heat sink 3 bottom surface with by printed circuit and the accompanying circuit board that consists of 4 thereof is connected, the aluminium base of circuit board 4 bottom surfaces is connected with the heat-radiating substrate 51 of fin 5 by heat-conducting cream, 1, lens with chip 2 be encapsulated into heat sink on.Pyroconductivity due to heat sink 3 is far away higher than lens 1, therefore it is that scioptics 1 transmit that the heat that chip 2 produces only has small part, all the other most heats be all along the illustrated direction of arrow by heat sink 3 and the path of fin 5 distribute, then carry out heat exchange with air.Although such LED lamp radiator structure is reliable and stable in the conveying of electricity, Shortcomings part on radiator structure: the ⑴ heat dissipation direction is single, and inefficiency just seems in the conduction of heat.Because the heat major part of LED lamp chip 2 conducts to heat-sink unit by heat sink 3, conduct to atmosphere by heat-sink unit again, and the fin 5 that existing heat-sink unit adopts is generally all to be engaged with the radiating surface of LED by heat-radiating substrate 51,52 of radiated ribs are intervally arranged perpendicular to heat-radiating substrate 51, as shown in Figure 1, namely only limit on the heat conduction direction of LED lamp, radiated rib 52 is set, radiating surface is limited; ⑵ the thermal resistance number of plies is many, and namely the LED lamp chip 2 heat major part of distributing is that multiple media such as fin 5 by scolder h, heat sink 3, circuit board 4, heat-conducting glue just can conduct on heat-sink unit, has weakened hot conduction efficiency; ⑶ in the situation that without forced draft, its radiating efficiency is not high, and when particularly assembling high-powered LED lamp, radiating efficiency is very unbalanced.Because described radiated rib 52 arranges along the heat conduction direction, in the situation that without forced draft, the zone of close heat-radiating substrate 51 is the air-flow dead angle often, cold air is difficult to add in this zone, thereby affects the radiating efficiency of fin 5.
