Description
Technical field
The present invention relates to LED street lighting technical field, be specifically related to a kind of LED street lamp of heat sinking device.
Technical background
LED (Light Emitting Diode, light emitting diode) street lamp promptly uses the illuminating lamp of LED as light source, and it is the very important part in the inside, public illumination field.Be characterized in white light emitting diode, have efficient, safety, energy-saving and environmental protection, characteristics such as the life-span is long, response speed is fast, colour rendering index height by GaN based power type blue-ray LED and yellow fluorescent powder synthesizing efficient.
Advantages such as exactly because led light source have energy-saving and environmental protection, life-span length, vibration resistance, control is flexible, response speed is fast, in field of street lamp lighting, increasing people selects LED as road-light light-source.Deep enforcement along with China's energy-saving and emission-reduction state basic policy, green illumination has been included one of energy-conservation key project in, under the guiding of these favourable policies, illuminating product manufacturing enterprise quantity surpasses 30% surprising speed development with annual growth, and developing at present and produce with the white light LEDs is thousands of nearly families of lighting enterprise of light source.
The core of LED is exactly a wafer, (wafer is to be made of P-type semiconductor and N-type semiconductor).Occupy an leading position in the hole in P-type semiconductor, mainly is electronics in N-type semiconductor, and the centre is a SQW.When electric current when the LED anode flows to negative electrode, the P-N junction barrier reduces, electronics and hole are pushed SQW and recombination luminescence to.Along with the increase LED meeting blast of electric current, but heating is but very serious.Though the luminous efficiency of LED is very high in theory, in fact LED is used for 80% electric energy heating in the course of the work.So the heat of vast scale has greatly reduced the efficient of illumination, if heat can not in time conduct, causes chip temperature to raise, and also may have influence on the luminous color of LED.In addition, along with the rising of wafer operating temperature, the life-span of LED presents the index downward trend.Theoretically, the operating temperature of LED is low more good more, but requires the high packaging density of high brightness in the illuminator of street lamp, and this just has higher requirement to the heat radiation of LED.
Existing LED radiating mode mainly is to set about from the heat-sinking capability aspect that improves LED luminous efficiency and raising device.The approach that improves luminous efficiency generally is to change the wafer micro-structural or change LED external structure or the like.The heat-sinking capability that improves device is to select some high heat conduction, the material that thermal resistance is low on the basis of wafer for use.These prior aries no doubt can reduce the temperature of LED wafer effectively, but, improve heat sinking function on the basis of wafer is very difficult thing, especially Chinese domestic, the LED wafer manufacturer of independent research not, the forming that comes for some imports wafer to improve radiating efficiency on the level of wafer be very difficult thing.
Existing radiator mounting means generally is that this mode will directly increase the weight of the load of LED lamp bracket upper bracket with heat-radiating substrate and lamp body design also encapsulation together.Because metal material density such as radiator is big, hardness is also big, if because of reason such as blow, rain causes street lamp to founder the roadside accidentally, injure pedestrian and vehicle easily.The present invention has filled up the deficiency of these technology.
Summary of the invention
The present invention proposes a kind of LED street lamp of heat sinking device, mainly be to be transmitted to above the radiator that is installed on the LED street lamp lamp bracket mobile jib, thereby heat distributed by radiator by the heat of heat pipe with LED.
In order to realize the present invention, the technical scheme that adopts is: a kind of LED street lamp of heat sinking device, comprise light fixture (1), lamp bracket (2), radiator (3), be positioned at the heat pipe (4) of lamp bracket and light fixture, secondary fluid course heat pipe (402) in the sprue heat pipe (401) and light fixture is set in light fixture in the light fixture, secondary fluid course heat pipe (404) in the sprue heat pipe (403) and lamp bracket is set in lamp bracket in the lamp bracket distributes above the heat on the LED (101) is transmitted to radiator outside the light fixture.
Described heat pipe (4), be divided into sprue heat pipe (403), the interior secondary fluid course heat pipe (404) of lamp bracket in sprue heat pipe (401) in the light fixture, the interior secondary fluid course heat pipe (402) of light fixture, the lamp bracket, use the interior secondary fluid course heat pipe (402) of light fixture that LED is coupled together, use the interior sprue heat pipe (401) of light fixture that secondary fluid course heat pipe (402) in the light fixture is coupled together then.The columns that LED (101) arranges is an even number, arranges sprue heat pipe (401) in the light fixture between two adjacent row LED, and allows the interior secondary fluid course heat pipe (402) of light fixture that sprue heat pipe (403) in LED (101) and the light fixture is coupled together.
The mode that secondary fluid course heat pipe (404) is connected on the radiator (3) in the described lamp bracket is: be divided into branch by sprue heat pipe (403) in the lamp bracket, these branches connect the interior secondary fluid course heat pipe (404) of lamp bracket of radiator (3) exactly, and their link position is in an annular region (302) of radiator bottom.
Described radiator (3) separates with light fixture, and radiator inside is hollow-core construction, and the outside is radiator shutter (301), and the centre is the annular region (302) of radiator bottom, and inside is that radiator hollow-core construction (303) is beneficial to it is packed into lamp bracket.
Above technical scheme is by conducting heat to the radiator (3) that is positioned on the lamp bracket mobile jib, utilized allow mode that radiator separates with light fixture with radiator above lamp bar is transferred to the lamp bracket mobile jib, the hollow-core construction in the middle of it of dispelling the heat is beneficial to is inserted in the lamp bracket mobile jib with it.
The all heat pipes of technique scheme are arranged in the following way: from being connected with radiator to the heat radiation bottom along lamp bracket in the light fixture.To distribute from radiator from the heat of LED and to pass through secondary fluid course heat pipe (404) in sprue heat pipe (403) in sprue heat pipe (401) in secondary fluid course heat pipe (402) in LED (101) → light fixture → light fixture → lamp bracket → lamp bracket → radiator (3) successively.
The present invention is transmitted to above the radiator that is contained on the LED street lamp bracket mobile jib by the heat of design heat pipe with the LED lamp body, and allows the design of lamp body adopt the mode that seals, and its superiority is:
1, can effectively heat be transmitted to radiator from the LED wafer, and be dispersed in the air and go, prolong the service life of lamp.
2, can alleviate the pressure of lamp bar.
3, because radiator separates with lamp body, can design the lamp body of sealing, prevent that mosquito, moth and dust etc. from falling into lamp body and damaging circuit in the lamp body.
