Replaceable LED (light-emitting diode) energy-saving lamp

Abstract

The invention belongs to the technical field of lighting and specifically relates to a replaceable LED (light-emitting diode) energy-saving lamp adopting an LED as a power supply. The replaceable LED energy-saving lamp comprises a metal long support pipe, connecting plugs arranged at two ends of the metal long support pipe, a strip-shaped metal light band plate and a plurality of LED light sources arranged on the light band plate, wherein the light band plate is arranged at the lower part of the long support pipe and is in contact with the lower end surface of the long support pipe, and electrodes of the connecting plugs are electrically connected with the LED light sources through conducting wires. The replaceable LED energy-saving lamp is reasonable in structure and good in heat radiation performance, and has the advantages of energy conservation, environment friendliness, safety, long service life, elimination of stroboscopic effect, maintenance-free property and the like; and furthermore, the replaceable LED energy-saving lamp can be directly used for replacing an existing fluorescent tube under the condition of not changing a support of a fluorescent lamp in all places using inductive fluorescent lamps, thereby greatly saving financial and material resources.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a replacement LED energy-saving lamp using LED as a light source. Background technique [0002] Fluorescent lamps in the prior art belong to gas discharge lamps, also known as hot-cathode low-pressure mercury fluorescent lamps, which replace incandescent lamps and become the second-generation mainstream lighting source. The power of existing fluorescent lamps is mostly between 8 watts and 40 watts. For fluorescent lamps used in workshops and classrooms, each fluorescent lamp often needs to use two lamps connected in parallel to meet the requirements of light brightness. very huge. [0003] With the development of solid-state lighting, LED lighting, which combines multiple advantages, is gradually moving towards the third generation of new light sources. LED light source has changed the principle of incandescent lamp tungsten filament luminescence and fluorescent la...

AI Technical Summary

Problems solved by technology

Although high-power LED light sources have so many advantages, due to the influence of factors such as relatively high unit cost and poor heat dissipation, they have not been widely used in general lighting, especially how to fully solve them. Utilizing the resources of existing general-purpose T5, T8, T10, and n2 fluorescent light source lamp holders, if users want to use new LED light sources, they often have to dismantle the fluorescent lamp holder and reinstall a new LED lamp holder, resulting in replacement costs higher
