Utility model content
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, is provided with louvre on fluorescent tube, with the heat dispersion of the LED fluorescent lamp that provides, driving power and LED lamp plate are separated simultaneously, it can effectively be fixed, and its security performance, to improve the service life of LED fluorescent lamp.
The technical scheme that the technical problem that the utility model solves adopts is:
A kind of LED fluorescent lamp with louvre, comprise LED sight lamp fluorescent tube and driving power, the two ends of LED sight lamp fluorescent tube are provided with contact pin, the top that it is characterized in that fluorescent tube is provided with several rows of pore, on the fluorescent tube of the left and right sides of steam vent, be respectively equipped with row's air admission hole, driving power is provided with substrate, substrate two ends are provided with fixing hole, be provided with the protective sleeve suitable with driving power, driving power is inserted in protective sleeve, protective sleeve on counterpart substrate fixing hole is provided with perforation, be provided with screw bolt and nut, bolt is by the perforation of protective sleeve and the fixing hole nut screwing clamping of substrate, driving power is fixed in protective sleeve, the protective sleeve that is provided with driving power is inserted in fluorescent tube, fluorescent tube is provided with installing hole, by installing hole, protective sleeve is fixed in fluorescent tube with fixture.
In the time that LED light source is worked, the heat energy that light source distributes can add the air in fluorescent tube, hot-air is because convection action flows out from the several rows of pore on fluorescent tube top, cold air flows into from the air admission hole of steam vent left and right sides, make to form in fluorescent tube continual to flow cooling system, thereby the temperature in reduction fluorescent tube, reaches cooling LED pole plate, reduce the effect of LED light source internal temperature.The utility model is effectively guaranteed the service life of LED sight lamp, thereby effectively promotes the development of LED fluorescent lamp.The utility model is being arranged on driving power on protective sleeve; driving power is isolated by protective sleeve and LED lamp plate; improve security performance; driving power is positioned at protective sleeve simultaneously; separate with LED fluorescent tube; heating to driving power while having avoided LED fluorescent tube to use, has reduced the temperature of driving power, has increased the service life of LED fluorescent lamp.Reduce driving power simultaneously heating has been damaged LED light source, the protective sleeve of built-in driving power has been fixed on fluorescent tube by fixture, avoided prior art easily to occur that driving power, at lamp in-pipe, improves its security performance greatly.
When concrete enforcement, described bolt is for being provided with nylon bolt, and described nut is nylon nut, and the head of nylon bolt is provided with screw, and described fixture is nylon screw, and nylon screw screws in the screw of nylon bolt head by the installing hole of fluorescent tube.
The beneficial effects of the utility model are: the utility model is provided with louvre on fluorescent tube, has improved radiating efficiency, thereby assurance can be not too high with the temperature of the circuit board of LED lamp, extend the service life of the electronic component of LED lamp; The protective sleeve that is provided with driving power is fixed in fluorescent tube, and the heating to driving power while having avoided LED fluorescent tube to use, has reduced driving power heating is damaged LED light source, has improved security performance, has improved the service life of LED fluorescent lamp.
