Description
Technical field
The utility model relates to the LED lighting, specifically a kind of tubular lamp that uses the paster packaged high-power LED as light source.
Technical background
What tradition LED illuminating lamp tube adopted is that small-power type LED is as light source, low-power LED is welded in the plastics fluorescent tube of the sealing of packing into then on the circuit board, because the low-power LED structure is after luminescence chip is fixed on support, with epoxy resin the luminescence chip envelope is irritated, the heat that is produced during chip operation is difficult for coming out, the heat that a plurality of LED produce in the fluorescent tube can't distribute in the sealing fluorescent tube simultaneously, and the encapsulating structure of low-power LED and fluorescent tube overall structure have determined traditional use low-power LED to make illuminating lamp tube and caused light decay and dead lamp situation easily.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of good heat dissipation effect, the paster packaged high-power LED tubular lamp that light decay is little.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of paster packaged high-power LED tubular lamp, comprise great power LED, aluminum base PCB plate, radiator, driving power, fluorescent tube end socket and lampshade, this great power LED is welded on this aluminum base PCB plate pad, this aluminum base PCB plate is fixed on this radiator, this driving power is fixed in this radiator two ends, this lampshade and this radiator connect and compose hollow cylinder, and this fluorescent tube end socket is connected in this radiator end and seals described hollow cylinder.
As preferably, this radiator is rectangular curved body, comprises planar section and curvature portion, and excavation has rectangular recess on its rectangular planes, and its curved surface outwards extends some fin symmetrically.
As preferably, this lampshade is the hollow cylinder with axially open, and inner wall surface thereof is made as zigzag, and the inner wall surface thereof opening is provided with two grooves of symmetry.
As preferably, this both sides, radiator plane fin inserts to move freely in this lampshade peristome groove and connects and composes hollow cylinder.
As preferably, between this aluminum base PCB backboard face and this radiator groove floor, establish and be coated with thermal grease.
After adopting technique scheme, because great power LED is welded on and is fixed on the radiator again on the aluminum base PCB plate pad, reduced the heat accumulation of paster packaged LED self, owing between this aluminum base PCB backboard face and this radiator groove floor, establish and be coated with thermal grease, and the radiator back side is provided with some fin, has further improved the integral heat sink effect.Better heat radiating effect has solved the problem that led chip long-time hot operation causes light decay and dead lamp.In addition, lampshade inner face zigzag helps LED and enlarges irradiated area, and described driving power is directly installed in the fluorescent tube, and the fluorescent tube end socket can directly insert civil power, and driving power, as seen this product with compact structure, easy to use need not be installed outside fluorescent tube in addition.
Description of drawings:
Fig. 1 is a parts assembly relation structural representation of the present utility model.
Fig. 2 is that parts shown in Figure 1 assemble the successfully vertical sectional structure schematic diagram in back.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of paster packaged high-power LED tubular lamp, comprise great power LED 1, aluminum base PCB plate 2, radiator 3, driving power 4, fluorescent tube end socket 5 and lampshade 6, this great power LED 1 is welded on the pad of this aluminum base PCB plate 2, this aluminum base PCB plate 2 is fixed on this radiator 3, this driving power 4 is fixed in this radiator 3 two ends, this lampshade 6 connects and composes hollow cylinder with this radiator 3, and this fluorescent tube end socket 6 is connected in these radiator 3 ends and seals described hollow cylinder.
