Accompanying drawing explanation
Fig. 1 is the perspective view of an embodiment of a kind of LED lamp tube of the present utility model;
Fig. 2 is the cross-sectional view of an embodiment of a kind of LED lamp tube of the present utility model.
The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 2, end cap 500, the LED light source structure at the body two ends that propose an embodiment of a kind of LED lamp tube of the present utility model, comprise body, are sheathed on.The drive unit that LED light source structure comprises LED-baseplate 300, is evenly laid in some LED lamp bead 400 in LED-baseplate 300, is electrically connected with LED lamp bead 400, LED-baseplate 300 is made up of glass-fiber-plate.End cap 500 comprises end cap cylinder 501, the end face sheet 502 be placed on end cap cylinder 501 one end.Body comprises the plastic tube 200 of the light-permeable with high-termal conductivity, be tightly placed in the glass tube 100 outside plastic tube 200, plastic tube 200 internal face is provided with and suitablely with LED-baseplate 300 engages and supply LED-baseplate 300 to slide the draw-in groove 201 passed in and out, glass tube 100 comprises main body section, in what main body section two ends extended outwardly out be embedded in end cap cylinder and the port position bonded by thermoplastic and end cap cylinder 501 madial wall, the thickness of port position is less than the thickness of main body section, end cap cylinder 501 is into a single integrated structure with end face sheet 502, end cap 500 and tubular body form hollow cavity.
The drive unit that LED light source structure comprises LED-baseplate 300, is evenly laid in some LED lamp bead 400 in LED-baseplate 300, is electrically connected with LED lamp bead 400, LED-baseplate 300 is made up of glass-fiber-plate, and the drive unit be electrically connected with LED lamp bead 400 is placed in end cap 500.Existing LED-baseplate 300 generally adopts the good aluminium base of radiating effect to make, but the expensive of aluminium base thus make the cost of LED lamp also very high.The utility model adopts glass-fiber-plate to make LED-baseplate 300, under the condition guaranteeing certain radiating effect, the price of glass-fiber-plate, far below the price of aluminium base, therefore adopts glass-fiber-plate greatly to reduce as the LED lamp tube cost made by LED-baseplate 300, more meets level of mass consumption.
Body comprises the plastic tube 200 of the light-permeable with high-termal conductivity, the glass tube 100 be tightly placed in outside plastic tube 200, and plastic tube 200 is set to off-white color.Such structural design, eliminate the harm that tradition selects the cumbersome process that then glass tube 100 sprays fluorescent material on glass tube 100 internal face to cause workman's health with spray fluorescent material pollution on the environment and powder injection process, structure is simply novel, production process is simple, aesthetic in appearance, nontoxic pollution-free.Plastic tube 200 is set to off-white color not only can block fluorescent tube internal structure, also plays scattering, guide-lighting effect.LED light line is by after plastic tube 200, and light becomes evenly soft, and visual effect is splendid, eliminates light pollution.The glass tube 100 of overcoat, glittering and translucent, make fluorescent tube entire normalization attractive in appearance.Plastic tube 200 is more durable compared with glass tube 100, not cracky, also protects LED light source structure well, and fluorescent tube can not be scrapped because of the fragmentation of glass tube 100, durable in use.Traditional fluorescent tube directly adopts glass tube 100, establishes LED circuit board in glass tube 100, because glass tube 100 is than being easier to fragmentation, remote-effects are to the service life of whole lamp.
End cap 500 is made up of insulating materials.Be provided with conductive metal sheet inside end face sheet 502, conductive metal sheet extends conductive pin 503 outwardly through end face sheet 502, and conductive metal sheet is electrically connected with LED light source structure by connecting wire.
End face sheet 502 is provided with some heat radiation cylindrical voids 504.
End cap 500 and tubular body form hollow cavity.
The heat produced when the high-termal conductivity of plastic tube 200 makes LED lamp bead 400 work passes rapidly, heat conduction is fast, heat dishoarding, end cap 500 and tubular body form hollow cavity, and the heat produced when LED lamp bead 400 works and the heat of drive unit reject heat to fluorescent tube each position inner by hollow cavity.And the heat radiation cylindrical void 504 that end face sheet 502 is provided with makes fluorescent tube inner ventilation breathe freely, heat, by heat exchange, is dispersed into rapidly in extraneous air.Heat dishoarding, ensure that the long-term normal work of LED light source structure, extends the service life of LED light source component, durable in use.
Existing LED lamp tube, junction, the LED-baseplate 300 of end cap 500 and body generally all adopt glue to bond with the junction of body, the glue that such connected mode uses not only not environmentally but also glue occurs aging along with the service time of fluorescent tube thus adhesive effect becomes worse and worse, junction is concavo-convex not whole, affect lamp body attractive in appearance, and glue is bonding agent, there is certain toxicity, also can cause certain harm to the health of environment and workman; LED-baseplate 300 is once install, and when breaking down, examine and replace extremely bothers.For solving above-mentioned existing issue, plastic tube 200 internal face of LED lamp tube of the present utility model is provided with and suitablely with LED-baseplate 300 engages and supply LED-baseplate 300 to slide the draw-in groove 201 passed in and out, draw-in groove 201 can install LED-baseplate 300 like a cork, without the need to using the adhesive with certain toxicity and environmental pollution; Or when LED-baseplate 300 breaks down, directly can skid off LED-baseplate 300 and carry out examine and replace, alleviate maintenance workload, structure is simply novel, environmental and durable, and maintenance cost is low.In the process that glass tube 100 is shaped in scorification, the thickness being set to port position is less than the thickness of main body section.Port position is made to have certain viscosity by the port position of thermoplastic glass tube 100, then end cap 500 is inserted in rapidly, port position is bonded on end cap cylinder 501 madial wall after cooling, production process is extremely simple, low cost of manufacture, nontoxic pollution-free, also eliminate use adhesive carry out being connected and fixed brought adhesive can occur aging, can not durable in use, there is the reverse side effects such as certain toxicity, contaminated environment.And the thickness of port position is less than the thickness of main body section, make the end cap 500 that is just inserted in consistent with the diameter of main body section, LED lamp tube is overall smooth-going regular, does not have concave-convex hand feeling, aesthetic in appearance.
Therefore; it is simply novel that the utility model achieves a kind of structure, specious, without the need to spraying fluorescent material; without the need to special equipment; without the need to bonding agent, simple and convenient assembly is quick, and production efficiency is high; low cost of manufacture; the high-termal conductivity of plastic tube and stability have protective effect to LED light source structure, durable in use, the LED lamp tube of long service life.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
