Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, a LED fluorescent lamp with good heat dissipation performance comprises a lamp tube body and an LED assembly, wherein the section of the lamp tube body is circular, the lamp tube body comprises a first half tube 1 and a second half tube 2 which are clamped with each other, the section of the first half tube 1 and the section of the second half tube 2 are semicircular, and the LED assembly comprises a lamp plate 3 and LED lamp beads 4 arranged on the upper surface of the lamp plate 3. Half 2 upper ends of pipe are equipped with the mount pad 5 that the symmetry set up down, mounting groove 6 has been seted up on the opposite face of mount pad 5, swing joint has mounting panel 7 in the mounting groove 6, be equipped with spring 8 between the up end of mounting panel 7 both sides and the last top surface of mounting groove 6, spring 8's upper end fixed connection is at the last top surface of mounting groove 6 promptly, and the lower extreme of spring 8 is installed at mounting panel 7 upper surface, LED subassembly block is in mounting groove 6, specifically, the both sides block of lamp plate 3 is between top surface and mounting panel 7 on mounting groove 6. The advantage that wherein set up spring 8 is because 3 thicknesses of the lamp plate of the LED subassembly of different models can differ, and set up spring 8 and can make and have certain headspace between mounting panel 7 and the mounting groove 6, can satisfy the lamp plate 3 installation of multiple model thickness, has increased the application scope of the lamp body. The upper surfaces of the mounting plates 7 on the two sides of the spring 8 and the LED assembly are provided with limiting baffles 9, and the mounting plates 7 are provided with a plurality of radiating holes 10 in the abutted positions with the LED assembly. The lower part of the mounting groove 6 is provided with a limiting bottom plate 11, and the limiting bottom plate 11 is used for limiting the pressing-down degree of the mounting plate 7 and preventing the heat-conducting fins from being pressed to 12. The mounting panel 7 below is equipped with a conducting strip 12, the both sides of conducting strip 12 and the inside wall sealing connection of half pipe 2 down, the lower surface of conducting strip 12 is equipped with a plurality of heat conduction silks 13, heat conduction silks 13 outwards extend and run through the lateral wall of half pipe 2 down, conducting strip 12 is towards the arc structure of mounting panel 7 one side hunch-up. The outside of mount pad 5 is equipped with the draw-in groove, first half 1 lower extreme is equipped with card strip 14 with draw-in groove matched with, and first half 1 passes through card strip 14 joint in the draw-in groove.

The utility model discloses during the use, push down mounting panel 7 downwards for the top surface pulls open enough distance on mounting panel 7 and mounting groove 6, inserts lamp plate 3 from the one end of half pipe 2 down after that, loosens mounting panel 7 after the completion, and mounting panel 7 compresses tightly lamp plate 3 under the restoring force of spring 8, thereby with LED subassembly block on mount pad 5, the one end of half pipe 2 will be gone into along the draw-in groove card strip 14 of half pipe 1 at last, make half pipe 1 and half pipe 2 inseparable joint can. To the heat dissipation process of LED fluorescent lamp, LED subassembly during operation generates heat, and its heat scatters and disappears to conducting strip 12 of half tub of 2 cavity of resorption down through louvre 10, transmits for conducting wire 13 by conducting strip 12 again, and is at last through conducting wire 13 with the heat give off the external world, because the end of conducting wire 13 is direct and external contact, so can strengthen the heat transmission effect, and conducting strip 12 and the inside wall sealing connection of half tub of 2 down, can cross the moisture and get into half tub of 2 upper chambers of resorption, influence LED subassembly. In addition, the LED subassembly during operation, the temperature of 3 intermediate positions of lamp plate is the highest, consequently is the design of conducting strip 12 and is the arch-up towards mounting panel 7 one side for the distance of conducting

strip

12 and 3 temperature highest departments of lamp plate shortens, can accept the heat of the 3 highest temperature departments of lamp plate fast, has accelerated the radiating rate.

Finally, it should be noted that: these embodiments are merely illustrative of the present invention and do not limit the scope of the invention.
