Abstract
The utility model provides an LED (Light Emitting Diode) street lamp adopting a thermal radiation and sectional type heat radiation structure. Both a macromolecule CD (Circular Dichroism) thermal radiation coating is coated on an aluminum profile heat radiation frame where an LED light source is installed, so that the heat radiation frame has a heat radiation function of far infrared thermal radiation so as to promote the heat energy to diffuse outside from the heat radiation frame; and structurally the LED light source is divided into a light source module with certain power and is installed on the heat radiation frame with relative width sectionally, so as to form an LED light source unit; in accordance with the requirements that different street lamps have different powers, N LED light source units are installed on aluminum profile edge frames at two sides of the street lamp transversely; the LED light source units are spaced for certain distance as the passage through which the heat flows. The heat generated when each LED light source unit works can obtain a heat flowing condition from up to bottom, so that the heat generated when the LED works is supplied with a good heat radiation condition with heat conduction, heat radiation and heat flowing.
Description
Technical field: a kind of LED street lamp that adopts heat radiation and segmented radiator structure, it relates to semiconductor light-emitting-diode illuminating product technical field.
Background technology: since semiconductor diode LED white light technical application since the illuminating product technical field, under numerous illuminating product producer made great efforts, the art designs level improved constantly.Yet as the heat dissipation problem of one of LED bottleneck technology, still remain further to be optimized, influence the luminous efficiency of LED street lamp to overcome the heat-sinking capability deficiency, cause light decay seriously to reduce service life.
Thermodynamics is told us, and heat radiation is exactly the heat transmission, and its mode has three kinds: hot conduction, heat flow, heat radiation.When material itself contacted with other material, the heat conduction was just claimed in the transmission of heat, and its photoelectric conversion rate of led light source only about 30%; All the other then generate electric heating; The radiator structure that this part heat, tradition are continued to use is that light source board is installed on the mounting plane of aluminium section bar radiator, and the radiating fin at the radiator back side is assembled each other; The heat that produces during LED work then is trapped between the radiating fin through conduction, can not form good thermal convection current technical conditions.And heat radiation is to rely on electromagnetic wave to transmit heat, and is middle without any need for medium, like daily being seen sunshine, warm oneself by a fire etc.But the applied radiating mode of current LED street lamp generally only limits to the heat conduction, and has ignored heat flow and thermal-radiating art designs and application.
Summary of the invention: the utility model provides a kind of LED street lamp that adopts heat radiation and segmented radiator structure, and it is made up of front and rear cover (1), (4), led light source unit (3) of light fixture locking aluminium section bar frame (2) and the aluminium section bar frame of installing on the led light source unit (3) (2).Light fixture is installed in led light source unit (3) on the aluminium section bar frame (2) by front and rear cover (1), (4), and led light source unit (3) comprising: the aluminium section bar framework (305) of the lens die of LED secondary light-distribution (301), silica gel sealing pad (302), led light source module (303), LED heat radiation carrier (304) and coating macromolecule CD heat loss through radiation coating.With CARBURIZING FURNACE FOR STAINLESS FASTENER lens module, silica gel sealing pad, led light source module are fixed on the screw hole position (306) of led light source heat radiation carrier (304), thereby form a led light source unit.In the light fixture rear end cap (4); Can lay the driving power (401) of led light source; The input of driving power is connected with the lamp stand power supply through binding post (402); The driving power output then is connected with the high temperature resistant power line of led light source by binding post (403), and high temperature resistant power line is welded on the led light source module (303) through aluminium section bar frame (2) and via through wires hole (307); Connection road lamp cap on the rear end cap (4) supplies lamp holder to be connected with lamp stand with the structure (404) of lamp stand arm; The cover plate of rear end cap (405) is topped above rear end cap, fixes with CARBURIZING FURNACE FOR STAINLESS FASTENER.By the requirement of street lamp different capacity, can N led light source unit be installed on the aluminium section bar frame of street lamp both sides, each space, led light source unit certain distance is as the passage of thermal convection current.According to the basic principle that hot-air rises, cryogenic gas can upwards be taken away heat energy, and the heat that produces during each led light source cell operation all can obtain heat flow condition from bottom to top, and heat is spread rapidly.The LED street lamp of this employing heat radiation and segmented radiator structure; The heat that is produced when working to LED provides hot conduction, heat radiation, heat flow, triple good heat radiating condition that possesses, the simple LED road lamp cooling better effects if that adopts hot conduction technique pattern of tradition.
