Description
Technical field
The utility model relates to that LED lighting source, particularly radiator structure are simple, a kind of water-refrigeration LED road lamp of rapid heat dissipation.
Background technology
Along with the continuous development of LED material epitaxy and chip technology, the LED luminous efficiency improves constantly, and its application is also progressively widened.Brainstrust estimates one after another that also LED will replace incandescent lamp and fluorescent lamp becomes lighting source of new generation.The LED lighting source is compared with fluorescent lamp with traditional incandescent lamp, and huge advantage is arranged.At first the LED volume is little, and the life-span is long, and structure closely can realize the large tracts of land array, moreover LED do not contain harmful lead and mercury, has avoided the pollution to environment simultaneously; LED uses the dc source of low-voltage to drive, and does not therefore have the 50Hz stroboscopic of traditional lighting light source; Traditional illuminating lamp radiation area can produce a large amount of heat, and the radiation area of LED mainly concentrates on visible region mainly at infrared region, produces heat hardly, is a kind of cold light source, and is therefore not only energy-conservation but also eliminated electromagnetic wave beyond the visible light to the harm of human body; The packaged back of LED anti-vibration, security are good, can be applied under the various rugged environments, and the LED response time is short and be degradation failure.So many significant advantages are arranged just, and we have reason to believe that LED will become the green illumination light source of 21st century gradually.
LED belongs to high power light source as light source applications of new generation when the light fixture, mainly need resolve heat radiation and luminous intensity distribution two large problems.At present, occurred so-called high-power LED street lamp product on the market, utilized high-power LED light source to replace the light source of conventional road lamp, except will solving the luminous intensity distribution problem, heat dissipation problem also is the key issue that LED street lamp product needed solves.General LED street lamp often adopts complicated radiator structure in order to solve heat dissipation problem, and therefore not only volume is bigger, heavy, and radiating effect is also unsatisfactory.
The utility model content
For solving the heat dissipation problem of above-mentioned high-power LED street lamp, the utility model is intended to propose a kind of water-refrigeration LED road lamp.
The technical scheme in the invention for solving the above technical problem is: a kind of water-refrigeration LED road lamp, the great power LED diode is installed on the substrate of good heat conductivity, it is characterized in that: substrate is connected with heat sink fitting tightly, and heat sink and water self-circulating device form good heat conduction and be connected.
The utility model great power LED diode is by inlaying or the mode and the substrate of bonding are connected and fixed, substrate and heat sink to fit tightly welding fixing, and great power LED forms array on substrate, driven by drive circuit.The water self-circulating device is successively by water inlet pipe, the water tank that has water filling port, outlet pipe with pass the loop that heat sink pipeline serial connection forms connection; Water inlet pipe is connected the bottom of water tank sidewall, and outlet pipe is connected the top of water tank side; The groundwork principle of water self-circulation system is to utilize the temperature variant principle of water density, when coolant-temperature gage during greater than 4 ℃ temperature rising density reduce, this moment, temperature higher water can float and the lower water of temperature can sink, can take away heat sink unnecessary heat in this way, thereby constantly cool off heat sink.The water self-circulating device also can be directly for having the water tank of water filling port, heat sinkly fit tightly and be welded in the water tank bottom surface.
The beneficial effects of the utility model are: with the heat-conducting substrate that great power LED is installed of street lamp and heat sink to fit tightly welding fixing, be connected by heat sink and water self-circulating device being formed good heat conduction, to be gathered in heat sink heat because heat sink heat radiation is heated water tank water takes away, flow and utilize water to cause variable density to produce owing to being heated, therefore can take away continuously and dispel the heat being gathered in heat sink heat by water tank, make LED be in all the time under the lower temperature in this way and work, thereby keep higher luminous efficiency; The timely heat radiation that makes yield LED improves the service life of whole lamp to improve its service life.
Description of drawings
Fig. 1 the utility model embodiment one structural representation;
Fig. 2 is the utility model embodiment two structural representations;
Among the figure: 1. great power LED; 2. substrate; 3. heat sink; 4. heat sink pipeline; 5. water inlet pipe; 6. water tank; 7. water filling port; 8. outlet pipe.
The specific embodiment
Below in conjunction with accompanying drawing and each embodiment the utility model is further specified.
Embodiment one
A kind of water-refrigeration LED road lamp as shown in Figure 1, great power LED 1 are installed on the substrate 2 of good heat conductivity, and promptly great power LED 1 diode is by inlaying or the mode and the substrate 2 of bonding are connected and fixed, and it is fixing that substrate 2 and heat sink 3 fits tightly welding; The water self-circulating device is successively by water inlet pipe 5, the water tank 6 that has water filling port 7, outlet pipe 8 with pass the loop that heat sink 3 pipeline 4 serial connections form connection; Water inlet pipe 5 is connected the bottom of water tank 6 one sides, and outlet pipe 8 is connected the top of water tank 6, and heat sink 3 form good heat conduction with the water self-circulating device is connected.Because adopt pipeline with water tank 6 and heat sink connection, the housing that the utility model water tank 6 can be installed on street lamp when therefore using is independent outward, or water tank and street lamp shell combination fixed together, the outward winding seal cover of the water filling port 7 on the water tank 6, inject water toward water filling port 7, in water tank 6 and pipeline, all fill with water, screw the seal cover of water tank 6 water filling ports 7, start power supply, circuit board in the street lamp drives great power LED 1 work, and LED is converted to luminous energy another part to an electric energy part and then is converted to heat energy; The heat that LED produces is transmitted to heat sink 3, and the water self-circulating device by heat sink 3 more than heat take away, make LED be in all the time under the lower temperature in this way and work, thereby keep higher luminous efficiency, the whole LED road lamp system also is in comparatively stable duty.The groundwork principle of water self-circulating device is to utilize the temperature variant principle of water density, when coolant-temperature gage during greater than 4 ℃ temperature rising density reduce, this moment, temperature higher water can float and the lower water of temperature can sink, make cooling water flow into water tanks 6 and the cooling water of outlet pipe 8 flows out from water tank 6 from water inlet pipe 5, can take away heat sink 3 unnecessary heats in this way, thereby constantly cool off heat sink 3.Be that the utility model utilizes water to come heat sink 3 of LED road lamp cap is cooled off in the self-loopa characteristic in when heating, simple in structure, cost is low, good heat dissipation effect.
