Technical field
The utility model relates to a kind of light fixture, relates to a kind of LED fluorescent lamp specifically.
Background technology
When general illumination, use incandescent lamp and fluorescent lamp usually at present, particularly in bigger space,, often use a plurality of fluorescent lamps, as classroom illumination, meeting room illumination, auditorium illumination etc. in order to obtain better illuminating effect.Because fluorescent lamp uses mercury vapour more, after long-time the use, mercury vapour can accumulate on lamp socket, causes the illuminating effect variation, and the life-span reduces simultaneously.The fluorescent tube that uses and other illuminating lamp tubes all are to make the interior filament of pipe be subjected to thermoluminescence by electric current at present, or heat makes inner mercury produce steam, and send strong ultraviolet ray, this incandescent lamp and fluorescent lamp in use, it is bigger that most of electric energy all consumes in heating energy consumption.
Patent Office of the People's Republic of China has announced that on April 14th, 2010 publication No. is the patent application document of CN101694268A, name is called: dimming LED fluorescent lamp, this light fixture comprises fluorescent tube, connecting line and switch, described fluorescent tube comprises transparent outer tube, is located at the lamp holder at transparent outer tube two ends, is located at the lamp base on the lamp holder, lamp base is connected on the switch by connecting line, be provided with the PCB wiring board in transparent outer tube inside, be connected with lamp base, on the one side of PCB wiring board, be welded with regularly arranged light emitting diode, also comprise adjustable potentiometer in addition, be used to regulate electric current and voltage.This light fixture is regulated the color and the brightness of light by regulating electric current and voltage, but because this light fixture comprises a plurality of light emitting diodes, heat dissipation problem can occur in use,, accumulation of heat occur and then can have influence on result of use and service life if it is untimely to dispel the heat.
Summary of the invention
The utility model has mainly solved: there is the problem that energy consumption is big, service life is short in the fluorescent lamp of general illumination when using, and provides that a kind of energy consumption is low, the LED fluorescent lamp of long service life.
The technical solution adopted in the utility model is: a kind of LED fluorescent lamp comprises that cross section is the lamp housing of arc strip, is connected and the Transparent lamp shade that matches, the aluminium base that has installation position, LED lamp source, a plurality of LED lamps source, constant-current drive circuit and lamp socket with lamp housing; Described aluminium base is fixed on the plane of lamp housing, and described plane is parallel with the prolonging direction of lamp housing, and LED lamp source is fixed on the aluminium base; Described Transparent lamp shade is the curved cylinder of cross section, and lamp housing has two draw-in grooves parallel with the lamp housing prolonging direction on its arcwall face, and draw-in groove is positioned at the both sides of lamp housing and matches with Transparent lamp shade, and the both sides of Transparent lamp shade are stuck in draw-in groove; Described constant-current drive circuit is fixed on an end of lamp housing, and is positioned within the space of lamp housing and Transparent lamp shade parcel; Described lamp socket one end has columniform installing hole, and the other end of lamp socket has two through holes, is fixed with two power pins in the through hole; The end of Transparent lamp shade and lamp housing is nested in the installing hole of lamp socket.
The LED lamp has the effect of low energy consumption with respect to common fluorescent lamp, and the LED lamp is installed on the aluminium base, and aluminium base has good heat-conducting, the heat that the LED lamp produces can be distributed, and increases the service life of LED lamp; The supply terminals of constant-current drive circuit is connected with the power pin of the lamp socket at two ends respectively by lead, the power output end of constant-current drive circuit is connected with the power end of aluminium base, aluminium base is fixed on the lamp housing plane relative with Transparent lamp shade, the power pin of lamp socket is inserted in the power supply lamp socket of common fluorescent lamp, and the LED fluorescent lamp just can throw light on as fluorescent lamp.
As preferably, described lamp housing is an aluminium section bar.Aluminium section bar, cost is low, good heat conduction effect and easily processing.
As preferably, described lamp housing is provided with some radiating grooves outward.Radiating groove helps the heat radiation of light fixture, prolongs the service life of light fixture.
As preferably, radiating groove is arranged along the prolonging direction of lamp housing.Radiating groove is parallel with the prolonging direction of lamp housing, makes the easy to process of radiating groove.Radiating groove also can be arranged along other directions, or be various patterns.
As preferably, described lamp housing is along having through hole on its prolonging direction, and secondly through hole can save the lamp housing material in order to wiring.
As preferably, lamp socket is cylindrical.
The beneficial effect that the utility model is obtained is: 1) by the use of aluminium base and heat-dissipating casing, improved radiating effect, avoided having improved the safe handling coefficient because of hot-spot causes damage, prolonged service life; 2) adopt the LED lamp, saved the energy; 3) adopt Transparent lamp shade, can improve radiation response, can protect LED lamp source simultaneously.
