Abstract

Disclosed is an LED low power consumption lamp tube which can be mounted on the common fluorescent lamp bracket. An LED (light-emitting diode) is used as the light source of the lamp tube. The lighting tube composed of a plastic light transmission lampshade, a metal radiation shell, a circuit board, a standard universal fluorescent lamp tripod is an LED lamp tube with the same shape and installation size as the common fluorescent lamp tube. The utility model is mostly characterized in that the LED low power consumption lamp tube can be used to directly substitute the common fluorescent lamp tube and is applicable for any lighting occasion.

Description

Use the general fluorescent tube of LED

Technical field

The utility model relates to a kind of LED low-power consumption fluorescent-lamp tube that can be installed on the common daylight lamp bracket, belongs to the low energy environment-friendly products, can substitute common fluorescent tube.

Background technology

Along with economic development and technological progress, the luminous efficacy of LED can surpass 100 lumens/watt at present, LED (light emitting diode) has begun to join lighting field, bulb, fluorescent tube, lamp string, the light fixture of various use LED have begun to produce, though existing enterprise is at the lamp of open tubular aspect alternative fluorescent lamp, but just simply LED lamp bar is encapsulated in the round tube, just the tubular lamp bar of picture fluorescent lamp can't directly substitute fluorescent tube.Chinese patent data 200410027618.3,200510073753.3, the disclosed LED fluorescent lamp of ZL200520002000.1, ZL200520034739.0 all can't directly use as fluorescent tube by retrieval, the heat dissipation problem of its LED does not solve, can only use as the ornamental lamp hole of low-light (level), can't substitute fluorescent tube and do the long-term use continuously of lighting source.

Summary of the invention

The utility model has overcome above-mentioned the deficiencies in the prior art, and a kind of general fluorescent tube of LED that can reach lighting source is provided, and directly substitutes fluorescent tube and uses.The utility model does not need inflation, does not need glass shell, good impact resistance, and shock resistance is good, is difficult for fragmentation, is convenient to transportation, does not add mercury in the light source, helps protecting environment.

The realization of the utility model purpose is finished by following technical scheme:

The utility model mainly is made of the metal core printed circuit board that circuit and LED are housed, semicircle heat dissipation metal shell, standard universal fluorescent lamp head, semicircle plastics transparent lamp shade.

Bridge heap rectification circuit is housed on the metal core printed circuit board, a plurality of LED forms illuminating source, power input is connected on the standard universal fluorescent lamp head by lead-in wire, fluorescent tube does not have positive-negative polarity.

LED is welded on the metal core printed circuit board.Metal core printed circuit board is fixed on forms good heat conductor in the heat dissipation metal shell, and the heat that produces when can be with LED luminous in time dispels the heat, and solves at present ubiquitous because of the overheated serious light decay phenomenon that reduces of LED brightness that causes.

The groove that semicircle plastics transparent lamp shade protruding end embeds semicircle heat dissipation metal shell is just in time formed the cylinder of fluorescent tube, and two ends are loaded onto the standard universal fluorescent lamp head and promptly formed the general fluorescent-lamp tube of LED.

User for present use tradition ballast Fluorescent lamp bracket can directly use above-mentioned fluorescent tube; The adopted power source special of new clothes Fluorescent lamp bracket substitutes traditional ballast.

The utility model has the advantages that: energy-saving safe, no mercury environmental protection, long service life.
