Because LED is electronic devices and components, heat dissipation problem governs development and the application of great power LED always.Along with the power ascension (more than 1W) of single LEDs, the transformation efficiency of LED reduces, and caloric value increases, and resistant to elevated temperatures LED chip and the domestic product substantially not having practicality of fluorescer, high performance product cost is higher, is not suitable for spread and uses.Domestic way relatively more current is at present, reaches the luminous flux of needs with the LED lamp bead series connection of a large amount of 1W, or falls power to 3W use by the LED lamp bead of specified 5W, obviously can reduce caloric value.But this way needs a large amount of raw material with artificial.The great power LED of integrated form is in fact also be packaged together in a large amount of low power chipset, and very high on cost, luminous flux is also less than single high-power lamp pearl.Active forced convertion heat radiation due to fan electromotor and the requirement of LED to power supply inconsistent, power supply must be two independent circuits, cost and reliability all compare and is difficult to control, and fan needs extra electric energy and energy-conservation object to run counter to.
Summary of the invention
Technical problem to be solved by this invention is, provide that a kind of structure is simple, good heat dissipation effect, manufacture and self power generation active heat removal LED easy for installation, cost is low.
Self power generation active heat removal LED of the present invention includes the housing that has inner chamber, and be provided with LED-baseplate in the middle part of housing cavity, the front of LED-baseplate is placed with LED lamp bead, arranges translucent cover below LED lamp bead; Housing rear portion and front portion are respectively arranged with air inlet and air outlet, be heat dissipation channel, be provided with radiator fan in heat dissipation channel between air inlet and air outlet; The back side of described LED-baseplate is connected with semiconductor temperature differential generating sheet, and the low temperature side of semiconductor temperature differential generating sheet connects the radiator with radiating fin, and radiator is arranged in heat dissipation channel; The power supply lead wire of described radiator fan is connected with semiconductor temperature differential generating sheet.
Described LED-baseplate is simultaneously as the ceramic substrate of semiconductor temperature differential generating sheet high temperature side.
Described radiator surrounding is also provided with additional cooler, and the substrate of additional cooler is directly connected with LED-baseplate.
Described radiator fan, between air inlet and radiator, is also provided with S shape wind inlet channel between radiator fan and air inlet.
Have at least a pair air inlet to be arranged on cover top plate and base plate, form vertical communicating structure, hard Air Filter is set in air inlet simultaneously.
Described air outlet is arranged on housing bottom surface, and is provided with rain cover inside air outlet.
Advantage applies of the present invention exists: 1, utilize by the heating of semiconductor temperature differential generating sheet to LED light source, forms the power supply of drive fan, makes the active heat removal of LED not need extra power supply, simplify control system, reduce cost; 2, radiator and additional cooler are set simultaneously, heat sink part can be regulated to act on the heat of semiconductor temperature differential generating sheet, and then regulate generated energy and rotation speed of the fan, thus balance and the stable operation of cooling system can be reached; 3, the rain cover by arranging S shape wind inlet channel and air outlet place can improve the ability of its outwork; 4, the air inlet structure of up/down perforation and the hard Air Filter of air inlet setting, can either play dustproof effect, rainwater can be utilized to carry out automatically cleaning to Air Filter simultaneously.
