Abstract

The invention provides an LED (light-emitting diode) streetlamp adopting a heat radiation and sectional type heat-dissipating structure. The LED streetlamp not only adopts a high-molecular CD radiation heat-dissipating coating coated on an aluminium-profile heat-dissipating frame arranged on the LED light source, so that the heat-dissipating frame has a heat-dissipating function of far-infrared heat radiation, the outward dissipation of the heat from the heat-dissipating frame is enhanced; on structure, the LED light source is divided into modules with certain power, and the modules are arranged on the heat-dissipating frame with relative width in a sectional manner so as to form an LED light source unit; and N LED light source units can be arranged on aluminium-profile frames at the two sides of the streetlamp, and are arranged at certain interval so as to be used as a channel for heat convection. The heat generated when each LED light source unit works can meet the heat-convection condition from bottom to top, so that the good radiating conditions of thermal conduction, thermal radiation and thermal convection are provided for the heat generated when the LEDs work.

Description

Adopt the LED street lamp of heat radiation and segmented radiator structure

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, thermal convection current, 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 thermal convection current and thermal-radiating art designs and application.

Summary of the invention: the present invention provides a kind of LED street lamp that adopts heat radiation and segmented radiator structure; It had both adopted macromolecule CD heat loss through radiation coating to be coated on the aluminium section bar heat-dissipating frame that led light source installs; Thereby make heat-dissipating frame possess the heat sinking function of far-infrared thermal radiation, impel heat energy from heat-dissipating frame to external diffusion, structurally again led light source is divided into the module of certain power; Segmentation is installed on the heat-dissipating frame of relative width; Constitute a led light source unit,, can N led light source unit be installed on the aluminium section bar frame of street lamp both sides by the requirement of street lamp different capacity; 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 thermal convection current 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, thermal convection current, triple good heat radiating condition that possesses, the simple LED road lamp cooling better effects if that adopts hot conduction technique pattern of tradition.
