Abstract
The invention discloses an air cooling device for LED (Light Emitting Diode) fluorescent lamps. The air cooling device comprises a circuit wiring board, wherein a surface mounted LED is mounted on the wiring board; a lamp tube is installed outside the wiring board; plugs are mounted on both ends of the lamp tube; and the plugs are connected to the LED circuit by a constant current driving converter through wires. The cooling device is characterized in that a minitype axial flow fan is installed inside one end of the lamp tube; the mintype axial flow fan and the LED circuit use a power supply in common; and the two ends of the lamp tube are communicated with air. The scheme has the main characteristics that a minitype axial flow fan is installed inside one end of the lamp tube, and the two ends of the lamp tube is communicated with the air, causing the air inside the lamp tube to flow, such that heat generated in the LED lamp tube can be dissipated by the air driven by the fan, thereby avoiding heat accumulation in the tube and ensuring normal light emission and service life of the surface mounted LED.
Description
Technical field
The present invention relates to the LED fluorescent lamp, particularly relate to LED fluorescent lamp air cooling equipment.
Background technology
Led light source is a light source that temperature dependency is stronger, variation of temperature will directly cause the service life of LED fluorescent lamp, under the condition that constant current drives, the luminous flux of LED fluorescent lamp raises along with temperature and descends, to make LED cause expendable light decay and in the higher temperature environment, use for a long time, this is because based on present semiconductor fabrication, 80% energy distributes by heat exchange pattern in the input power of LED, and the heat loss through radiation unlike incandescent lamp, therefore at present all LED fluorescent lamp factory commercial cities adopt aluminium base pcb to be close to reach LED heat radiation purpose on the semicircle aluminum pipe, owing to used aluminium section bar and aluminium base pcb, production cost occupies high-leveled and difficult following, and this makes the LED fluorescent lamp be difficult to one of fundamental cause that enters the ordinary people man.And by actual use proof, because aluminium section bar and aluminium base pcb dispel the heat by the mode of conduction, the atmosphere draught-free in the fluorescent tube is so radiating effect is still undesirable.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, provide air in a kind of fluorescent tube to circulate and make good heat dissipation effect in the fluorescent tube, can avoid fluorescent tube inner product amount of stored heat and influence the LED fluorescent lamp air cooling equipment of LED luminous flux.
The technical solution used in the present invention is in order to achieve the above object:
LED fluorescent lamp air cooling equipment, comprise electric crossover board, paster LED is installed on the terminal plate, fluorescent tube is installed outside terminal plate, plug is installed at two of fluorescent tube, and plug drives converter through lead by constant current and connects led circuit, it is characterized in that in of fluorescent tube the minisize axial-flow blower fan being installed, minisize axial-flow blower fan and led circuit are with using power supply, and fluorescent tube two communicates with air.
The invention discloses a kind of fluorescent lamp of forming by light emitting diode (LED or title paster LED), its main feature is that the minisize axial-flow blower fan is installed in of fluorescent tube, fluorescent tube two communicates with air, make the air in the fluorescent tube produce mobile, the heat that produces in the LED fluorescent tube drives air by blower fan and dissipates, heat savings in avoiding managing, the maintenance paster LED is luminous and service life normally.
Dust cover is installed in two of described plastics fluorescent tube.In two of fluorescent tube, dust cover is installed, and wherein one dust cover is outside the minisize axial-flow blower fan, prevent that dust in air etc. from sucking in the fluorescent lamp, particularly avoid contamination by dust paster LED and terminal plate, can also prevent that in addition insects such as cockroach, fly from crawling into fluorescent tube.
Described minisize axial-flow blower fan and led circuit and constant current drive the converter parallel connection.
Described fluorescent tube is made of plastics.Adopt the plastic material manufacturing cost to economize.
Described terminal plate is made of plastics.Adopt the plastic material manufacturing cost to economize.
