Abstract
The utility model relates to an LED lamp, in particular to a T8 type LED lamp for replacing a T8 type fluorescent lamp, which mainly includes a housing, a lampshade, two lamp holders, an LED light source comprising a plurality of light emitting diodes, and an electronic circuit board. Power plugs are arranged on the two lamp holders, a constant-current voltage reducing circuit is integrated on the electronic circuit board, an input terminal of the electronic circuit board is connected with the plugs of the two lamp holders, and an output terminal of the electronic circuit board is connected with the LED light source; and the LED light source is fixed on the housing and covered by the lampshade, and the two lamp holders are arranged at two ends of the housing respectively. Compared with the prior art, the utility model utilizes the constant-current voltage reducing circuit to drive the LED (light emitting diodes) to give out light, the light is subjected to the diffuse reflection of the lampshade, the heat generated by the light emitting diodes is sent out by aluminum casting profile, and the T8 type LED lamp has the advantages of high luminance, long service life, low energy consumption and low total power consumption compared with the T8 type fluorescent lamp, so as to perfectly take the place of the present T8 type fluorescent lamp.
Description
Technical field
The utility model relates to a kind of LED lamp, is meant a kind of T8 type LED lamp of the T8 of replacement type fluorescent lamp especially.
Background technology
Along with world energy sources is in short supply, low charcoal is all being said in the whole world, so green energy conservation electric lighting product is used widely, and original T8 type fluorescent lamp in market most widely used model, along with the popularization and the third generation energy-conserving product LED appearance of green energy conservation product, this type of fluorescent tube will progressively be eliminated.Existing this fluorescent tube has following shortcoming:
One, fluorescent tube is frangible;
Two, fluorescent tube contains mercury, and environment and human body all are harmful to;
Three, lamp tube service life is short;
Four, fluorescent tube is a negative resistance charactertistic, needs the high pressure starter during startup.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming of T8 type fluorescent lamp in the prior art, and a kind of T8 type LED lamp of the T8 of replacement type fluorescent lamp is provided, and its power consumption is lower keeping under the situation of same brightness.
The utility model adopts following technical scheme:
A kind of T8 type LED lamp that replaces T8 type fluorescent lamp, mainly comprise led light source and electronic circuit board that housing, lampshade, two lamp holders, a plurality of light emitting diode are formed, this two lamp holder is provided with attaching plug, be integrated with the constant-current decompression circuit on this electronic circuit board, the input of this electronic circuit board is connected to the plug of this two lamp holder, and the output of this electronic circuit board is connected to this led light source; This led light source is fixed on this housing, and this lampshade is located on the led light source, and this two lamp holder is separately positioned on the two ends of this housing.
Described housing is the cast aluminium section bar, is the cylindrical body of being made up of an arc and a flat board with a cavity, and described electronic circuit board is installed with in this cavity, and described led light source is installed on this flat board.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the T8 type LED lamp of a kind of T8 of replacement type fluorescent lamp of the present utility model comes the driving LED lumination of light emitting diode by the constant-current decompression circuit, penetrate through the lampshade diffuse reflection then, the heat that light emitting diode produces distributes through the cast aluminium section bar, compare with T8 type fluorescent lamp, have brightness height, the life-span is long, energy consumption is little, overall power consumption is little advantage, can replace existing T8 type fluorescent lamp fully.
