Abstract
The utility model discloses a plate-tube LED (light-emitting diode) lamp radiator module. A heat radiation structure of the plate-tube LED lamp radiator module is formed by vertically connecting an aluminum base board 5 which is compounded with a copper foil circuit layer 1, an insulation layer 3 and LEDs 2, and processed with a plurality of round holes with a plurality of aluminum tubes 4 with the same diameter as the round holes in an expansion riveting manner. The plate-tube LED lamp radiator module has the characteristics of being simple in structure, good in heat dissipation effect, low in cost and reliable in use and being easy for batch production.
Description
Technical field
The utility model relates to a kind of band-tube type LED lamp radiator module, especially is applied to outdoor street lamp, High-Pole Lamp, Projecting Lamp and indoor venue and uses etc. in the high-power LED lamp.
Background technology
Under current global energy environment in short supply, energy savings has become trend of the times, and the LED illumination is the pollution-free industry of energy-conservation a, low-carbon environment-friendly, and its development is in the ascendant, is subjected to national encouragement and support on policy.LED is just with its energy-saving and environmental protection, light source health and high life, various advantage sane developments such as environment friendly and pollution-free.At present, the LED lighting engineering reaches its maturity, and this makes the city illumination reducing energy consumption become possibility.LED street lamp, High-Pole Lamp, Projecting Lamp are just with the traditional illumination market of swift and violent velocity shock.The high-power LED light source life-span is long, be more than 4 times of high-pressure mercury lamp life-span, after using 100,000 hours, light decay is lower than 30%, and power consumption only is 1/10th of incandescent lamp, can be-40 ℃~70 ℃ operate as normal, do not produce any environmental pollution, maintenance cost is low, has light projector distance, characteristics that the floodlight area is big during use, has thoroughly solved the various disadvantages that conventional lamp exists.Although the development speed of LED street lamp is swift and violent, the heat dissipation problem of LED light fixture will be a long-standing problem in the long term.
Generally speaking, the heat that produces during led light source work accounts for it and consumes about 70% of general power, and the heat that produces when it is luminous will make LED knot surface temperature too high, and then influence product life cycle, luminous efficiency, stability if can't derive.
Light decay is the main cause that high-power LED street lamp can not long-term work, reduces an important method of light decay and improves its heat radiation exactly.The light decay of present most of LED street lamps can not satisfy instructions for use.Relevant experimental data shows 1200 hours light decays behind the bright lamp, and best is 8%, and the poorest is 26%, and average out to 14%. is from the heat transfer theory system, and we have operable heat transfer means: conduction, convection current, radiation and phase-change heat transfer (for example heat pipe).Therefore on the heat dissipation problem that conducts heat in other words, the measure that we can take is visible, limited.
Weight is also very important on the illuminator out of doors, and the street lamp height is about ten meters, and High-Pole Lamp then has tens of rice high, if too heavy danger just increases, constitutes a threat to for the safety of pedestrian and vehicular traffic, especially runs into typhoon, earthquake and all may produce accident.
The quality of LED light fixture heat radiation is the key that determines its life cycle, luminous efficiency, and its weight is also very important on illuminator, and can its price also be very important factor large tracts of land substituting on traditional light fixture.
Summary of the invention
The purpose of this utility model is: it is low to design a kind of cost, in light weight, the structural system of good heat dissipation.Cooling system is divided into: forced heat radiation and natural heat dissipation, we at first will get rid of the forced heat radiation structure system and can only take the self-heating cooling system for outdoor lighting.According to the natural law of cooling of newton in 1701 invention (Q=K * T * S), we understand and are: 1. radiator is a draughty structure, 2. the spreader surface temperature will be as far as possible near the heater temperature, 3. enough cooling surface area.We design a kind of band-tube type LED lamp radiator module based on this law, by counting the led circuit heat radiator assembly that a dried aluminum pipe 4 and aluminium base 5 link together, it is characterized in that: this radiator structure is by being compounded with copper foil circuit layer 1, insulating barrier 3 and LED2, and be processed with the aluminium base 5 of several circular holes, connect mode 6 with the isometrical aluminum pipe 4 vertical riveting connection sides of expanding of several and this circular hole and link together.Realized that as radiating end area is big by aluminum pipe 4, lightweight purpose; Aluminum pipe 4 links together by the vertical riveting connected mode 6 that expands with aluminium base 5 simultaneously, the heat that LED2 sends is directly delivered on the aluminum pipe 4 by aluminium base 5, need not make aluminum pipe 4 and aluminium base 5 reach the almost effect of isothermal by heat-conducting silicone grease 8 these obstruction heat transfer links; Aluminum pipe 4 connects as one by the vertical riveting connected mode 6 that expands with aluminium base 5, has realized penetrating effect up and down.The nature law of cooling is followed in this design fully.Heat radiation was best under it had possessed with power through experiment test, cost is minimum, weight is the lightest, the processing and manufacturing characteristic of simple.

Embodiment
[0017] the utility model is to realize like this, a kind of band-tube type LED lamp radiator module, by counting the led circuit heat radiator assembly that a dried aluminum pipe 4 and aluminium base 5 link together, it is characterized in that: this radiator structure is by being compounded with copper foil circuit layer 1, insulating barrier 3 and LED2, and being processed with the aluminium base 5 of several circular holes, aluminum pipe 4 vertical the expand riveting connected modes 6 isometrical with several and this circular hole link together.Realized that as radiating end area is big by aluminum pipe 4, lightweight purpose; Aluminum pipe 4 links together by the vertical riveting connected mode 6 that expands with aluminium base 5 simultaneously, the heat that LED2 sends is directly delivered on the aluminum pipe 4 by aluminium base 5, need not make aluminum pipe 4 and aluminium base 5 reach the almost effect of isothermal by heat-conducting silicone grease 8 these obstruction heat transfer links; Aluminum pipe 4 connects as one by the vertical riveting connected mode 6 that expands with aluminium base 5, has realized penetrating effect up and down.Heat radiation was best under it had possessed with power through experiment test, cost is minimum, weight is the lightest, the processing and manufacturing characteristic of simple.Different power, the moulding of street lamp, High-Pole Lamp, Projecting Lamp that will make according to us.Calculate size, the quantity of used module.Be installed on structural member and lamp housing, the lamp bracket.The whole lamp heat dispersion of test is by adjusting LED arrange spacing and aluminum pipe caliber, wall thickness; To reach optimum Match; Finish whole lamp design.
