Description

A kind of LED lamp
Technical field
The present invention relates to a kind of LED lamp for throwing light on, particularly relate to a kind of LED shot-light, LED lamp affixed to the ceiling, LED ceiling lamp, LED fluorescent tube, LED bulb, LED street lamp, LED desk lamp, LED Tunnel Lamp etc.
Background technology
LED light emitting diode has not leaded, mercury than conventional light source, without stroboscopic, energy-conserving and environment-protective, long service life, fast response time, vibration resistance, easy care, brightness is high, energy consumption is low, there is no the plurality of advantages such as ultra-violet radiation and environmental pollution, safety in utilization height and be widely used on electronic installation or lighting.
The light decay of LED light source is directly relevant with its junction temperature with its life-span.LED lamp, particularly high-power LED light source, when luminous, heat is concentrated, if the heat that LED chip produces distributes not in time, junction temperature is just very high, the life-span is just short.According to Jordi Arresse rule, 10 ℃ of the every reductions of temperature, the life-span will extend twice.Show according to the study, if junction temperature can be controlled at 65 ℃, the life-span of LED light source light decay to 70% just can be up to 100,000 hours.Because LED belongs to electroluminescence device, its heat can not distribute by radiation mode.In its photoelectric conversion process, only have 15 one 25% electric energy to convert luminous energy to, nearly all energy transform into heat energy of remaining electric energy, raises the temperature of LED light fixture.And for LED wafer integrated packaging light source, because wafer is more concentrated, luminous source region heat is high, be so just easy to cause the device temperatures such as LED chip too high.If can not distributing in time, a large amount of heats can cause series of problems: for example, can accelerate the device agings such as LED chip, reduction of service life, even can cause LED chip to burn; Make the wavelength generation red shift of blue-ray LED, and colourity to white light LEDs, colour temperature produces material impact, if wavelength shift is too much, departed from the absworption peak of fluorescent material, will cause fluorescent material quantum efficiency to reduce, affect light extraction efficiency; Temperature also has a significant impact the radiation characteristic of fluorescent material, along with temperature rise, fluorescent material quantum efficiency reduces, and radiation wavelength also can change, the change of fluorescent material radiation wavelength also can cause the variation of white light LED color temperature, colourity, and higher temperature also can be accelerated the aging of fluorescent material.Conventionally, the power of LED wafer integrated packaging light source is larger, and the distance of irradiation is also far away, and radiation response is better; But meanwhile, heat dissipation problem is more difficult to resolve certainly.Heat dissipation problem has finally restricted the raising of LED wafer integrated packaging light source power, also can only reach 25W in the relatively advanced U.S. of technology single LEDs wafer integrated packaging light source power peak power at present, LED heat dissipation technology has become the bottleneck of great power LED technical development.
The heat radiation of existing LED light source adopts following several modes conventionally: one, LED light source is combined with heat dissipation metal parts (as heat dissipation metal substrate, metal heat sink), fin, louvre, utilize the heat conduction and heat radiation effect of heat dissipation metal parts, reach and reduce heat dissipation metal part temperatures effect, the life-span of guaranteeing LED light source by extraneous lower temperature air heat exchange.This radiating mode, because existing louvre operated by rotary motion is in the side of heat-radiating substrate, and useless LED light source is separated, the heat that LED light source produces need first rise and distribute by louvre, and extraneous cold air also needs the louvre by being arranged on heat-radiating substrate side to reach LED light source.This radiating mode, because heat-radiating substrate is sealed towards a side of light cover, therefore can not form the gas heat dissipation channel of convection current, and louvre only horizontal direction is arranged, is unfavorable for cross-ventilation heat radiation, and radiating effect is bad.They are two years old, adopt fan forced convection mode to dispel the heat, utilize the air of the outer lower temperature of fan extracting lamp housing and the air of the interior higher temperature of lamp housing to carry out heat exchange, and heat radiation reduces air themperature in lamp housing through lamp housing outer surface, thereby LED component temperature, the life-span of guaranteeing LED light source.Fan cooling mode complex structure, cost is high, and itself consumes energy, and the more important thing is that the life-span of fan is also shorter than chip, and reliability is low, needs regular maintenance.It three is heat pipe and loop heat pipe heat radiation etc., hot pipe cooling structure complexity, and cost is high; Fin heat radiation, limited because of surface area, effect is bad equally.

4) on cooling base, be provided with and the integrated multiple chip fixing lug boss of cooling base, the area of cooling base is greater than the area at chip fixing lug boss top greatly, and LED chip is fixed in chip fixing lug boss by die bond mode.Greatly reducing so on the one hand dissipation of heat that LED chip produces is airborne intermediate path distance and has greatly increased and the contact area of the gas that dispels the heat in heat radiation gas, greatly reduce heat localization effect, can greatly improve radiating efficiency and make chip be held in suitable operating temperature, thus the long-life of maintenance chip and effectively luminous efficiency.Chip fixing lug boss and cooling base are one-body molded, and the heat that therefore chip produces only sees through cooling base and just directly distributes in air, therefore thermal resistance is little, radiating rate is fast, must not dispel the heat by other radiating piece, and radiating effect is just fairly good.The shade of keeping out that makes to be electrically connected light that wire sends LED chip drops to minimumly, is beneficial to optical secondary optimization owing to there being chip fixing lug boss! Save existing LED support, namely save the heat radiating metal part in LED support, and the multilayer intermediate link such as electrode metal pin, especially reduced the high thermal resistance producing between two parts of heat radiating metal part and cooling base, therefore thermal resistance is little, and the fast good heat dissipation effect of heat conduction is simple and reliable for structure, especially one-body molded design and the assembly technology that is more conducive to light source of chip fixing lug boss and cooling base, saves again cost.Therefore the present invention is simple and reliable for structure, and part is few, and thin thickness is easy to assembling, is specially adapted to the powerful occasion of light source requirements.
