Abstract

The present invention provides a LED lamp with high brightness. a uniform light-emitting surface and good heat dissipation. The LED lamp includes a LED strip and a cylindrical light guide body connected to the LED strip, wherein light emitted from the LED strip irradiates towards the light guide body and exits via the surface of the light guide body.

Claims

1. A LED lamp, comprising a LED strip and a cylindrical light guide body connected to the LED strip, wherein light emitted from the LED strip irradiates towards the light guide body and exits via the surface of the light guide body.

2. The LED lamp according to claim 1, further including a light guide connection plate arranged at a side of the light guide body and provided with a recess, and the LED strip is embedded in the recess.

3. The LED lamp according to claim 2, wherein the recess is in parallel with the light guide body, and light-emitting surface of the LED strip faces the light guide body.

4. The LED lamp according to claim 1, wherein the LED strip includes a plurality of LEDs provided thereon, and the plurality of LEDs are arranged in a line and equally spaced therebetween.

5. The LED lamp according to claim 4, wherein LEDs at both ends of the LED strip are arranged to respectively slant towards end surfaces of the light guide body close to them.

6. The LED lamp according to claim 4, wherein the LED strip further includes a plurality of divider resistors provided thereon, and each LED on the LED strip and one divider resistor are connected in series.

7. The LED lamp according to claim 2, further including a L-shaped backplate, and the LED strip is adhered to an inner surface of one side plate of the L-shaped backplate which is embedded in the recess of the light guide connection plate, and the other side plate of the L-shaped backplate is arranged outside the light guide connection plate.

8. The LED lamp according to claim 7, wherein material of the L-shaped backplate includes aluminum.

9. The LED lamp according to claim 7, wherein the LED strip is adhered to the L-shaped backplate by heat-dissipating adhesive.

10. The LED lamp according to claim 7, further including a driving power supply provided on an outer surface of the L-shaped backplate outside the light guide connection plate.

11. The LED lamp according to claim 1, wherein material of the light guide body includes polymethyl methacrylate (PMMA).
