Description

A kind of LED daylight lamp apparatus that can directly replace fluorescent lamp to use

Technical field

The utility model relates to lighting technical field, particularly relates to a kind of LED daylight lamp apparatus that can directly replace fluorescent lamp to use.

Background technology

Traditional fluorescent tube is claimed fluorescent lamp again, and is as shown in Figure 3, and lamp tube ends respectively has a filament; Be filled with the argon of trace and thin mercury vapour in the fluorescent tube; Scribble fluorescent material on the tube inner wall, send ultraviolet ray during gaseous conduction between two filaments, make fluorescent material send visible light; Owing to contain heavy metal pollution material " mercury ", make that the fluorescent tube of scrapping is very serious to the pollution of environment.

And the LED fluorescent lamp adopts light emitting diode as light source, and light efficiency is higher, more energy-conservation, longer service life, and more environmental protection.The LED fluorescent lamp energy-saving is up to more than 70%, and the life-span is more than 10 times of common fluorescent tube, almost is non-maintaining, does not have the problem that will often change fluorescent tube, ballast, starter, and the expense of saving of getting off half a year approximately just can gain cost.Become the ideal product that the current stage replaces fluorescent tube.

In the prior art, as shown in Figure 4, almost all LED fluorescent lamps all are the LED fluorescent lamps 19 that adopts built-in power on the market.So-called built-in power just is meant power supply is positioned over the fluorescent tube the inside.This built-in great advantage can be made direct replacement traditional fluorescent lamp tube exactly, and need not original circuit is done any change.For example: application number is 201120020876.4 Chinese utility model patent; " a kind of LED lamp with starter " disclosed; Its technical scheme comprises LED fluorescent tube and LED starter, and each end of LED fluorescent tube all is provided with two terminals, two terminal short circuits of LED fluorescent tube one end; Two terminals of the other end are distinct terminals; One of them distinct terminals is used for joining with an electric power incoming line, and another distinct terminals is joined through a terminal of LED starter and short circuit, and another terminal and another electric power incoming line of short circuit join.LED fluorescent tube and LED starter are installed on the inlet wire type lamp socket of two ends, and this has the compatible traditional two ends inlet wire type lamp socket of LED lamp ability of starter, and above-mentioned LED lamp has adopted the mode of built-in power.

But there is following shortcoming in this on-chip power formula LED fluorescent lamp: it is big that the power supply difficulty is changed in (1)., if power supply broken directly change whole LED fluorescent lamp will cause great waste much larger than the service life of power supply the service life of LED, if only change power supply, must rely on the professional that circuit is carried out dismounting and change again; (2) influence the luminous quality of LED.It is evenly soft inadequately etc. that the heat that sends makes that the LED fluorescent lamp in use can produce dazzle, shadow and bright dipping; (3) weak heat-dissipating.Because it is built-in that power supply adopts, the heat of power supply also just joins in the fluorescent tube, makes the heat radiation of LED increase difficulty again, has shortened the service life of LED; (4) cost recovery is high, and the built-in power formula has also increased the cost of the recycling of electronic waste, handles respectively because must split out power unit come again; (5) be difficult to reach the standard of safety.Because on-chip power makes a big impact to reaching the safety standard.

Application number is that 200920134372.8 Chinese utility model patent discloses " a kind of LED fluorescent lamp of external LED power supply "; Comprise LED daylight lamp body; Be connected with an external LED power supply on this LED daylight lamp body; Said external LED power supply comprises PCB circuit board, input and output terminal, power pack, and the PCB circuit board is built in the power pack, and input terminal is connected with LED daylight lamp body through PCB circuit board, lead-out terminal.Though the LED fluorescent lamp of the LED power supply that this is external has solved some defectives that on-chip power exists, its power supply installation needs to change original circuit, just can be fixed on the lamp plate of traditional fluorescent lamp.
