Technical field
The present invention relates to a kind of LED lamp, especially a kind of LED lamp of double-layer lampshade liquid-cooling heat radiation.
Background technology
Heat radiation is to having material impact in service life of LED lamp, a lot of large-sized fin heat radiations are adopted in the heat radiation of originally traditional LED lamp, the high radiator structure replacement that is connected gradually lampshade by wire of, cost large due to volume, its structure is that the connection metal silk pastes surface at the individual layer lampshade on radiator, wire by heat conduction transfers heat to the lampshade surface from radiator and dispels the heat, but this individual layer lampshade conducts heat inhomogeneous in conjunction with the wire heat radiation, radiating efficiency is limited, to extending DeGrain in service life of LED.
Summary of the invention
Goal of the invention of the present invention is that above-mentioned existing individual layer lampshade is inhomogeneous in conjunction with the wire heat transfer, radiating efficiency is limited in order to solve, the shortcoming that extends DeGrain service life to LED, a kind of LED lamp of double-layer lampshade liquid-cooling heat radiation is provided, the radiating efficiency of described LED lamp obviously improves, fully extend service life, little on light fixture weight and manufacturing cost impact.
In order to achieve the above object, the LED lamp of a kind of double-layer lampshade liquid-cooling heat radiation of the present invention's design, comprise lamp socket and lampshade, be connected with the LED substrate on lamp socket, lampshade is connected to an end of lamp socket, it is characterized in that described lampshade comprises double-deck inner cover and outer cover, form between two lampshades and fill with the liquid storage cylinder that cooling fluid is arranged, the sidewall outer surface of inner cover is covered with lamp socket and leads hot linked heat-conducting piece.The present invention is by the lampshade of double-layer structure, the heat transfer between inner cover and outer cover is completed in cooling fluid in the dependence liquid storage cylinder and the acting in conjunction of heat-conducting piece, during work, heat-conducting piece pastes to be beneficial on the inner cover sidewall heat energy diffusion is delivered to whole inner cover surface, complete heat transfer between inner cover and outer cover by cooling fluid again, more even in conjunction with the wire heat radiation than the individual layer lampshade, radiating efficiency is high, can greatly extend the service life of light fixture, and is little on light fixture weight and manufacturing cost impact.Need to reserve the flowing heat transfer that a certain amount of bubble space is beneficial to cooling fluid when wherein filling cooling fluid.
Improve and replenish as the further of said structure, the present invention also comprises any combination of following additional technical feature or these features.
Described heat-conducting piece infiltrates in cooling fluid.Heat-conducting piece infiltrates in cooling fluid, and the abundant contact heat-exchanging of cooling fluid and heat-conducting piece dispels the heat more even, helps to improve radiating efficiency.
Described lamp socket is threaded with lampshade, and lamp socket one end is threaded ends, and the link with lamp socket on inner cover and outer cover forms respectively threaded interior adapter ring and outer adapter ring, and an end of heat-conducting piece is connected on interior adapter ring and is close to lamp socket.Inside and outside cover and lamp socket adopt and are threaded, and are convenient to installation, repair; Heat-conducting piece is close to lamp socket, and lamp socket heat conduction is good, is beneficial to heat radiation.Described adapter ring can make with lampshade is one-body molded, interior adapter ring and inner cover, and outer adapter ring and outer cover all are made into integration.
Described lamp socket comprises a radiator and is connected in the lamp holder of radiator one end by connector, the other end of radiator is provided with the connecting portion that a threaded cannelure of sidewall forms and lampshade is spirally connected, described interior adapter ring is provided with the internal thread that matches, outer adapter ring is provided with the external screw thread that matches, and the LED substrate is connected on radiator.The effect of connector is insulation lamp holder and radiator; Inside and outside cover is screwed in cannelure by interior adapter ring and outer adapter ring separately and lamp socket is threaded, and the linkage section of lampshade and lamp socket all is hidden in cannelure, is not vulnerable to the outside and collides with and cause lampshade to connect looseningly even to come off.In addition, radiator can adopt the hollow cylindrical structure, and sidewall is established radiating fin, utilizes fin to make the radiator external cooling, and inner formation spatial accommodation is integrated in LED substrate and driver in light fixture simultaneously, can reduce the volume of LED lamp, and is easy to use.
Be embedded with a sealing ring between described interior adapter ring and outer adapter ring, described sealing ring is close to the bottom surface of cannelure, has the strip groove that matches with heat-conducting piece on the inwall of sealing ring.The effect of sealing ring is that the cooling fluid in liquid storage cylinder is sealed, and avoids cooling fluid to overflow from screw connection point, prevents that the cooling fluid minimizing from affecting radiating effect or flowing into inner cover breaking-up LED illumination; Groove and heat-conducting piece match and guarantee that sealing ring and interior adapter ring fit closely seamlessly, guarantee that sealing ring is to cooling fluid good seal in liquid storage cylinder.
Described outer adapter ring overcoat one sealing shroud, the end face of sealing shroud is close to the end face of ring slot outside.Sealing shroud is tightly placed in outside outer adapter ring and touch the end face of radiator, can prevent that the invasion and attack of extraneous dust or rainwater from entering lamp interior, guarantees lamp interior normal operation, good heat radiating; Sealing shroud has elasticity and certain altitude, can protect outer adapter ring and radiator connecting portion.
Described heat-conducting piece is the netted sidewall outer surface that pastes at inner cover.The netted contact area that can increase heat-conducting piece and cooling fluid and inner cover sidewall that pastes strengthens heat-transfer effect, improves radiating efficiency.Wherein netted heat-conducting piece can by injection moulding and inner cover is one-body molded makes or separable assembled.
Described heat-conducting piece surface scribbles reflective material layer.Reflectorized material can reduce heat-conducting piece to the obstruction of light conduction efficiency, and desalination dim spot phenomenon reduces the adverse effect to illumination.
Scribble heat-conducting medium in the gap of described LED substrate and radiator joint face.Heat-conducting medium can increase the contact area of LED substrate and radiator joint face, improves heat-conducting effect, and in actual the use, heat-conducting medium can adopt heat-conducting silicone grease or its similar substance.
Described inner cover and outer cover are the spherical crown shape, form the liquid storage cylinder of crescent section between two spherical crowns.The lampshade of spherical crown shape is identical with existing lampshade shape commonly used, is convenient to utilize existing device to process, and the liquid storage cylinder of crescent section is beneficial to coolant flow and conducts heat.
The present invention adopts double-deck inside and outside lampshade and cooling fluid between the two in conjunction with the heat-conducting piece acting in conjunction, realize conducting heat efficiently, existing individual layer lampshade in conjunction with the heat radiation of wire radiator structure evenly, efficient is high, good cooling effect, the service life of the more effective prolongation of energy LED light fixture, little on LED weight and manufacturing cost impact.
