Abstract

The utility model provides a LED daylight lamp, composed of a glass tube, two bulb holders at two ends and pins, wherein the glass tube comprises an internal printed circuit board with an electric circuit, the printed circuit board is welded with a LED light emitting diode, while the printed circuit board is electrically connected with the pins via wires. The utility model can completely use the material and size of former daylight lamp, without coating any material in the glass tube, while two ends of the tube are arranged with the bulb holders in former sizes, the printed circuit board and the bulb holders are connected by wires, thereby realizing the LED tube with same size as prior fluorescent lamp. The utility model has the advantages that the utility model has exchangeable property with prior fluorescent lamp at structure, with long service life, low power consumption, high light effect, and environment-friend in production and application.

Description

A kind of LED fluorescent lamp

Technical field

The utility model belongs to the led light source lighting technical field.

Background technology

The glass lamp coated inner wall fluorescent material that the illumination of present fluorescent tube is generally adopted and in fluorescent tube the mode of filling mercuryvapour.This mode improves a lot on photoelectric conversion efficiency than original tungsten filament solid luminescence mode.Extensively adopt, but the pollution of mercury metal pair environment is well-known in the whole world.

LED has been widely used in color lamp illumination, every field such as signal demonstration as a kind of advanced luminescent material.But the luminescent material of this new and effective, environmental protection how in conjunction with traditional lighting system, is widely used in the general lighting field more and also has many technical problems.

Summary of the invention

The utility model purpose provides a kind of and existing fluorescent tube structure and all on all four LED fluorescent lamp of overall dimension, can interchangeability completely be arranged with existing fluorescent tube on contour structures, and realize long-life, low-power consumption, high light efficiency and target of environmental protection fully all in producing and using.

The technical solution of the utility model is as follows:

A kind of LED fluorescent lamp, it has the lamp holder and the common fluorescent tube of forming of pin at glass lamp, two ends, printed substrate with an electronic circuit is installed in that glass lamp is built-in, welding LED light-emitting diode on the printed substrate, printed substrate is electrically connected with pin employing lead.This fluorescent lamp can adopt the glass lamp material and the size of original fluorescent lamp fully, need not apply any material in the glass lamp, the lamp holder of original size is still adopted on the fluorescent tube both sides, realize making and the on all four LED fluorescent tube of existing fluorescent tube overall dimension effective connection between printed substrate and the lamp holder with lead.

Described printed substrate is a strip, and there is the rubber contact mat both sides and glass lamp inwall contact site, with the position of fixing circuit board in glass tube, and avoids printed substrate to contact with the tube inner wall rigidity and causes damaging glass lamp.

Advantage of the present utility model: 1, utilize the light source of semiconductor lighting material LED light-emitting diode, can realize real long-life, low-power consumption, high light efficiency, non-maintaining characteristics as fluorescent lamp; 2, adopt glass lamp, than various organic optical materials better optical property is arranged all, and manufacturing cost is lower; 3, owing to adopt traditional fluorescent lamp pipe overall dimension, consistent with use habit and aesthetic habit that the user is traditional, accepted easilier by market; 4, the characteristic that in manufacturing and use, all has complete environmental protection.5, by adopting white and colored various light-emitting diodes, provide abundanter light color.6, having cancelled former fluorescent tube must pull the trigger by high pressure, under different voltage statuss, must adopt rectifier, starter, the drive circuit that inverter etc. are complicated, by adopting the electronic circuit of different driven, be built on the printed substrate, be applicable to common 220V, the power supply of AC and DCs such as 110V or 36V, 24V, 12V.

Description of drawings

Fig. 2: be the profile of this LED fluorescent tube;

Fig. 3: be the sectional view of this LED fluorescent tube.

Embodiment

Now further specify structure of the present utility model in conjunction with the accompanying drawings:

Referring to Fig. 1, this LED fluorescent lamp adopts glass material to make fluorescent tube 1, adopts lamp holder 2 and the pin 3 consistent with conventional fluorescent fluorescent tube profile.Referring to Fig. 2, be built-in with the printed substrate 4 of band at fluorescent tube 1, be welded with LED light-emitting diode 5 on the printed substrate 4, and be furnished with electronic circuit 6.Printed substrate 4 and connector 7 on the lamp holder 2 are fixed together, and printed substrate 4 adopts leads to be connected with pin 3 on the lamp holder 2, finishes the circuit connection.Printed substrate 4 is a strip, in conjunction with sectional view 3 as seen, printed substrate 4 both sides and glass lamp inwall contact site be rubber contact mat 8 fixedly, printed substrate is not contacted with tube inner wall generation rigidity can prevent that wiring board from damaging fluorescent tube, also can prevent the lamp holder far-end displacement of wiring board in fluorescent tube simultaneously.
