Description

A kind of LED fluorescent tube

Technical field

The utility model relates to lighting field, relates in particular to a kind of LED fluorescent tube with plug-in Control Component.

Background technology

Traditional daylight lamp fixture, the life-span of fluorescent tube is greatly about 3000 to 5000 hours, and the life-span of starter or stabilizer about 20,000 to 30,000 hours, the life-span of fitting structure part is over 100,000 hours.Thereby, in order to meet, often change fluorescent tube needs, the overall construction design thinking of light fixture is light fixture and the fluorescent tube interface of use standard, G13 interface for example, make fluorescent tube from light fixture, dismantle and to install at an easy rate, and do not need to use any instrument, and there is no safety problem yet, can be operated by general user.Stabilizer, because replacement frequency is fewer, is screwed on light fixture conventionally, and directly connecting power line, must be operated by qualified electrician during dismounting and split and connecting power line road.

The project organization of traditional fluorescent lamp tool, after LED light fixture occurs, the basis of its mentality of designing is no longer applicable, because the life-span of LED lamp holder can reach more than 100,000 hours, if the LED lamp holder of long service life, in between the effective life of whole light fixture, do not change necessity of LED lamp holder at all.This makes original object be to be convenient for changing the traditional fluorescent lamp pipe of fluorescent tube and the normal formula interface of light fixture, becomes and no longer includes meaning.Although current most of LED fluorescent tube on the market, in order directly to substitute original fluorescent tube, still adopt the interface of traditional standard G13, but new, complete LED light fixture does not need to be used the restriction of the G13 interface of traditional standard, also can reach the illuminating effect of traditional fluorescent lamp tool.

LED light fixture, except cap part has the advantages that to surpass 100,000 hours above life-spans, also has another one feature, and the life-span of the power drives that LED light fixture is used is on average about 20,000 to 30,000 hours, well below the life-span of LED lamp holder.This situation has produced a new instructions for use that is different from traditional fluorescent lamp tool to LED light fixture: the lamp holder life-span is very long, and the life-span of power drives is limited, and the general user who does not possess electrician specialty knowledge wants can be easy to and dismounting power drives safely.But LED Design of Luminaires at present on the market, power drives is all built in LED light fixture the inside, and dismounting is difficult for, and need to just can change power drives by professional electrician's tool using, obviously can not meet the new instructions for use to LED light fixture.
