Description

The LED fluorescent tube

Technical field

The utility model relates to a kind of lighting apparatus, relates in particular to a kind of LED fluorescent tube that is used to replace the traditional fluorescent lamp use.

Background technology

Household electricity illumination exposed installation is from the not good incandescent lamp of the high illuminating effect of initial caloric value, develop at present still at the better and energy-conservation fluorescent lamp of the chromatic rendition effect of extensive use, lighting apparatus is being followed to illuminating the color rendition degree better, more energy-conservation direction develops, at present, the new technology that LED lamp soon occurs is tending towards ripe, manufacturing cost is more and more lower, led light source has plurality of advantages with respect to fluorescent lamp commonly used, with the LED lamp identical with 20W fluorescent lamp lighting effect is that example is come comparison, the LED lamp not only service life be that traditional fluorescent lifetime is more than 10 times, and there are not ultraviolet ray or an infrared light radiation, the danger that does not also have mercury to leak, its light decay is half of traditional fluorescent lamp pipe light decay, operating temperature range is wider, its electric light conversion ratio is more near 100%, caloric value is little more energy-conservation, when equal illumination efficient, economize on electricity about 70% than traditional fluorescent lamp lighting, and the LED lamp body is long-pending less also solid more non-friable, therefore be more convenient for being provided with heat radiation, quantity can reach usually in the illumination of the LED lamp of 120-200 and enough reach the 100-200 lux, with respect to present fluorescent tube, meet general national production standard fully, more energy-conservation with respect to what fluorescent lamp had, no infrared, no ultraviolet, do not generate heat, colour rendering is good, no stroboscopic, advantages such as light is softer are more suitable for being used for various illumination occasions, as school, office, factory's streamline, the supermarket, reach-in refrigerator, hospital, squares etc. need good illumination effect, to eyes and the inirritative occasion of skin, also seldom can find at present the LED lamp lighting device of alternative conventional illumination device illumination on the market, and existing lighting apparatus can not be directly directly be connected use with traditional lamp socket.

The utility model content

Technical purpose of the present utility model provides a kind of can being installed in easily and has the LED fluorescent tube of realizing illuminations such as LED on the lamp socket of turning off the light day now.

For realizing above-mentioned technical purpose, the utility model LED fluorescent tube comprises the fluorescent tube as the transparent fluorescent lamp shape of lamp body, the alternating current-direct current transformer, lamp holder and some led light source modules, the led light source module comprises the LED lamp and has the LED lamp control circuit plate of LED control circuit, these some led light source modules are located at the fluorescent tube inside of transparent fluorescent lamp shape, lamp holder is fixedlyed connected with the fluorescent tube two ends, the input electrode of alternating current-direct current transformer is connected with lamp holder electrode, the input electrode of LED lamp control circuit is connected with the output of alternating current-direct current transformer, the output electrode of LED lamp control circuit is connected with the LED lamp.

These some LED control circuits are integrated on the strip circuit board, this strip circuit board is located in the fluorescent tube of fluorescent lamp shape, identical parallel rectangular circuit board one side of being located at of some LED light irradiation directions, the input electrode of LED lamp control circuit plate is connected with lamp holder electrode, and output electrode is connected with the LED lamp.

The LED control circuit of these some led light source modules is connected mutually, perhaps a plurality of LED control circuits are parallel with one another, output with the alternating current-direct current transformer is connected afterwards, connects mutually by a plurality of LED with proper number, reaches the lamp socket of turning off the light LED lamp and tradition day is combined illumination purposes.

Beneficial effect: LED fluorescent tube of the present utility model is made traditional fluorescent lamp form with the LED lamp, realize the illumination of LED lamp in conjunction with existing fluorescent lamp base, make things convenient for the exchange between LED lamp and the fluorescent lamp, can utilize existing traditional resource to use existing LED lamp and realize illumination, economize on resources and help the popularization of this LED fluorescent tube.
