Description
Technical field
The utility model relates to a kind of street lamp, particularly San Re LED street lamp.
Background technology
From national emergency start in 2003 since the semiconductor lighting engineering, " green illumination plan " includes national Eleventh Five-Year Plan in, caused governments at all levels and leader's great attention.National departments concerned proposes the annual saving 25% of city illumination the Eleventh Five-Year Plan period again recently.City illumination, actual is exactly street lighting, the saving means of street lighting, the non-semiconductor illumination does not belong to, and semiconductor lighting is trend of the times.
All there is the street lamp demonstration project many cities and even small town, and tens at least, thousands of at most small cups.Along with the further raising of efficient and being gradually improved of technology, very fast development will be arranged.
Present widely used road lighting light source mainly is based on second generation light source---the glow discharge spot lamp of high-pressure mercury lamp.Along with the continuous development of LED technology, the breakthrough of key technology, and the succeeding in developing of high-power, high-efficiency LED chip, the efficient of high-power LED light source has reached more than the 100lm/W, and the road lighting that is applied to the city has become possibility.At present, the patent No. is 200720148153.6 to have disclosed a kind of high-power LED street lamp, its structure comprises some LED lamps, aluminium sheet, shell, the Cu metal tubes that heat-conducting liquid is housed, fin, the LED lamp is fixed on the aluminium sheet, aluminium sheet is connected with Cu metal tubes, Cu metal tubes connects fin, and fin is connected with shell; The LED street lamp of this structure passes to aluminium sheet with the heat of LED lamp, then, by the Cu metal tubes that heat-conducting liquid is housed heat is passed to fin, and is last, by fin and shell heat scattered and disappeared; Adopt this structure, the derivation time of LED heat that lamp produces is long, and therefore, it is slower to dispel the heat; Because connecting in fin and the aluminium sheet Cu metal tubes is liquid all, heat transfer rate is slower, so the heat radiation of LED lamp.
Summary of the invention
The purpose of this utility model is in order a kind of LED street lamp to be provided, to utilize the utility model can improve the radiating efficiency of LED lamp, being convenient to the installation of LED lamp.
For achieving the above object, LED street lamp of the present utility model comprises shell, is located at metal substrate more than two and fin on the shell; On metal substrate, be provided with circuit layer; Fin is connected with shell and is connected with metal substrate; Described metal substrate is the metal tube of hollow and closed at both ends; Formed cavity is a vacuum cavity in the described metal tube, is provided with drop in the cavity; Described inner wall of metal tube is with capillary structure; Described metallic substrate surfaces is provided with the heat sink or led support of stamping forming LED more than two, and described LED lamp is encapsulated on the heat sink or led support of LED with the method for silica gel model.
Adopting this structure, because metal substrate is the metal tube of the hollow-core construction of sealing, and is vacuum in the cavity of hollow-core construction, and drop is housed in hollow-core construction, and inner wall of metal tube inwardly is provided with many capillary structures.When LED is logical power on after, produced a large amount of heats, these heats pass on the metal substrate, make the gasification rapidly on low-pressure state of heated metal substrate drop on every side, be diffused into rapidly then in the whole metal substrate cavity, fully carry out heat exchange with the capillary structure in the metal pipe-wall, thereby heat is conducted on the whole metal substrate, and then do heat transmission, thereby realize the heat that the LED lamp produces is dispelled the heat by a very large-area metal substrate by the fin that links to each other with metal substrate and environment on every side.Therefore, the metal substrate heat conduction of this structure is fast; Because the method for LED lamp by the silica gel model is encapsulated on the heat sink or led support of LED, like this, LED lamp easy for installation and can improve radiating efficiency; Because inner wall of metal tube like this, has increased the heat exchange area of aqueous vapor and metal pipe-wall with capillary structure.
Specialize as of the present utility model, the drop of described vacuum chamber is water or ethanol or ether.Adopt above-mentioned several liquid, these several liquid are in vacuum and the gasification easily of heating back.
Specialize as of the present utility model, described metal substrate is copper pipe or aluminum pipe or iron pipe.It is fast to adopt copper pipe or aluminum pipe or iron pipe to conduct heat.
Compared with prior art, because the method for LED lamp by the silica gel model is encapsulated on the heat sink or led support of LED, described LED is heat sink or directly punch forming on metal substrate of led support, fin is located on the metal substrate, and shell is connected with fin, therefore, it is fast to conduct heat, good heat dissipation effect; Owing to be provided with drop in the metal substrate cavity, the metal substrate inwall is with capillary structure, and therefore, the heat transfer of metal substrate is fast.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of metal tube and LED lamp.
The specific embodiment
LED street lamp as depicted in figs. 1 and 2 comprises shell 1, is located at metal substrate more than two 2 and fin 3 on the shell 1; Described metal substrate is copper pipe or aluminum pipe or iron pipe; On metal tube, be provided with circuit layer; Fin 3 is connected with shell 1, and is connected with metal tube; Described metal tube is the structure of hollow and closed at both ends, and its internal cavities is a vacuum; Be provided with the drop of water or ethanol or ether in the described cavity; Described inner wall of metal tube is with capillary structure 5; It is heat sink 6 that described metal tube surface is provided with stamping forming LED lamp, described LED lamp 4 usefulness silica gel model methods be encapsulated in LED heat sink on, described LED is heat sink, and also available led support replaces.
During the work of the LED street lamp of this structure, heat sink or led support passes on the metal tube heat that the LED lamp produces by LED, and metal tube is passed to fin with heat, by fin and shell heat is scattered and disappeared then; The diabatic process of described metal tube is: heat sink or led support passes on the metal tube heat that the LED lamp produces by LED, at this moment, the metal tube that is provided with the LED lamp partly is heated, conductive fluid in the metal tube drops in the environment gasification down of vacuum, be diffused into rapidly then in the whole metal substrate cavity, fully carry out heat exchange with the capillary structure in the metal pipe-wall, simultaneously, liquefaction after vaporized drop is caught a cold, then, flow to the high temperature place of metal tube, then repeat said process, because the changing steam state into from liquid and change liquid state then into repeatedly of the drop in the said process metal tube, when liquid state changes steam state into, take away heat at drop, on inner wall of metal tube, be provided with capillary structure, and metal tube is a cavity structure, therefore, conduct heat soon; Because drop is water or ethanol or ether, this drop just can be vaporized in lower temperature, and therefore, the temperature on the LED lamp is delivered to fin and shell easily; Because the metal tube surface is provided with the heat sink or led support of stamping forming LED lamp, therefore, LED lamp easy for installation can be improved the radiating effect of LED lamp.
