Description
Technical field
The utility model relates to LED field, and particularly a kind of be furnished with the LED light source module of high-efficiency radiator and the garden lamp by this LED light source module composition.
Background technology
LED is a kind of electronic device that can be luminous energy by electric energy conversion with diode characteristic.LED light fixture has the development prospect being expected most in lighting field, and its outstanding advantages is: luminous efficiency is high, and the monochromaticjty of light is good, spectrum is narrow, can directly send coloured visible ray without filtering; Its power consumption is few, and in same illuminating effect situation, power consumption is 1/8th of incandescent lamp bulb, 1/2nd of fluorescent tube; Long service life, average life span reaches 100,000 hours; Security reliability is strong, be conducive to environmental protection, and (cold light source caloric value is low, and non-thermal radiation can safe touch, is convenient to installation and maintenance; The element of the health risks such as not mercurous, sodium, discarded object is recyclable).
LED light source is generally to embed in lighting and uses, in the electric energy of driving light source, only have an appointment and 15% be converted into luminous energy, all the other 85% are converted into heat energy, if this part heat energy fails to derive in time and distribute, can cause light source chip temperature significantly to raise, high-temperature causes chip itself and potting resin performance to worsen, 2 ℃ of the every risings of component temperature, and light fixture reliability just will decline 10%.For example, have experiment to show, in the time that operating temperature is raised to 74 ℃ by 63 ℃, LED average life span will reduce 3/4.Be that the too high temperature rise of light source chip will cause that luminous efficiency reduces, and causes serious light decay, the lost of life.Therefore " heat radiation " become the important key technology of high-power LED lamp.So the design of good cooling system, the application of good heat sink material is most important.In other words, the design of radiating module has become the key element that ensures LED quality.
LED lighting belongs to the end prod of this industrial chain application, although technology door is lower relatively, except above-mentioned heat dissipation design key technology, its other technologies that need to solve also have following several respects: the performance of (1) light fixture and parameter designing, Industrial Moulding Design, optical design, circuit design, structural design, processing technology, production technology etc.Must consider correlative factor, arbitrary link occurs that deviation all can affect performance and the effect of product.(2) design of light fixture secondary light extraction efficiency.It comprises chip position design, high performance reflector-light cup lampshade design etc.(3) shape-designing.Light fixture profile should match with environment for use, and miniaturization attractive in appearance is comfortable durable.(4) low pressure constant-current source drives the use of design, high transmission rate mixed light material etc.
The weak point of LED lamp casing radiating module design is mainly manifested in: (1) lamp radiating shell versatility is poor.The radiator of die cast, a kind of design can only be used as a kind of light fixture specification, and remodeling is difficult, die sinking is expensive, totally unfavorable for the exploitation of new product.(2) light fixture product is difficult to realize seriation.Traditional LED light fixture seriation is more difficult, as: the light fixture of 100W can only be used the lamp outer casing radiator of 100W, and selectivity is strong, and the cost of seriation is very high.(3) heat-delivery surface is limited.In order to guarantee the radiating effect of light fixture, it is heavier that its radiating shell is generally all made.
The principle of design high-efficiency radiator be meet that fundamental strength requires in advance under, obtain maximum heat-delivery surface with minimum quality, to obtaining and heat exchange area and the heat transfer effect of surrounding air maximum.
