Description

A kind of LED fluorescent tube

Technical field

The utility model relates to fluorescent tube, especially relates to a kind of LED fluorescent tube.

Background technology

Light emitting diode (Light Emitting Diode, LED) is as a kind of green light source, has that luminous efficiency is high, power consumption is few, a long service life, safe and reliable and environmentally friendly advantage.Along with the lifting of people's environmental consciousness, LED matrix more and more receives people's concern, and the LED matrix application is also more and more wider, and wherein, the development of LED Lighting Industry is more and more rapider.

A very important application of LED illumination is the LED fluorescent tube, yet LED fluorescent tube of the prior art is that a section bar dispels the heat and driving is installed substantially, one side configures the LED luminescence chip, cause result for only having single face luminous, its lighting angle is less, and 120 degree left and right are only arranged.Therefore, be necessary to propose a kind of improvement, to improve the deficiency of prior art LED fluorescent tube.

The utility model content

The technical assignment of the technical problems to be solved in the utility model and proposition is that the prior art scheme is improved and improved, and provides a kind of LED fluorescent tube, to reach the purpose of large lighting angle.For this reason, the utility model is taked following technical scheme.

A kind of LED fluorescent tube, comprise the LED luminescence chip, the one LED substrate, the 2nd LED substrate, transparent lamp shade, connector, the one LED base lower surface and the 2nd LED upper surface of base plate are pasted together, the LED luminescence chip is fixed on a LED upper surface of base plate and the 2nd LED base lower surface by the mode of COB integration packaging, at a LED substrate, the 2nd LED substrate covering has transparent lamp shade, the transparent lamp shade two ends are equipped with connector, be located at the LED luminescence chip of a LED upper surface of base plate and the 2nd LED base lower surface and can realize double-side, effectively increase the lighting angle of LED fluorescent tube.

As a kind of improvement, a described LED upper surface of base plate and the 2nd LED base lower surface are equipped with plural LEDs luminescence chip.

As a kind of improvement, a described LED substrate, the 2nd LED substrate are transparent material.

As a kind of improvement, described LED luminescence chip is blue chip, and described transparent lamp shade scribbles fluorescent material.

As a kind of improvement, driving power is contained in described connector inside.

Owing to adopting technique scheme, the LED fluorescent tube that the utility model provides has advantages of that lighting angle is large.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the enlarged drawing of A part in Fig. 1.

In figure, LED luminescence chip 1, the one LED substrate 2, the two LED substrates 3, transparent lamp shade 4, connector 5.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

With reference to Fig. 1, shown in Fig. 2, the utility model has disclosed a kind of LED fluorescent tube, it comprises: LED luminescence chip 1, the one LED substrate 2, the 2nd LED substrate 3, transparent lamp shade 4, connector 5, the one LED substrate 2 lower surfaces and the 2nd LED substrate 3 upper surfaces are pasted together, LED luminescence chip 1 is fixed on LED substrate 2 upper surfaces and the 2nd LED substrate 3 lower surfaces by the mode of COB integration packaging, at a LED substrate 2, the 2nd LED substrate 3 coverings have transparent lamp shade 4, transparent lamp shade 4 two ends are equipped with connector 5, be located at the LED luminescence chip 1 of LED substrate 2 upper surfaces and the 2nd LED substrate 3 lower surfaces and can realize double-side, effectively increase the lighting angle of LED fluorescent tube.

The one LED substrate 2 upper surfaces and the 2nd LED substrate 3 lower surfaces are equipped with plural LEDs luminescence chip 1, effectively improve the overall brightness of LED fluorescent tube.

The one LED substrate 2, the 2nd LED substrate 3 are transparent material, do not lose the luminous flux of LED luminescence chip bottom surface and side, effectively improve the overall brightness of LED fluorescent tube.

LED luminescence chip 1 is blue chip, and transparent lamp shade 4 inboards scribble fluorescent material, after the blue light that LED luminescence chip 1 sends mixes with fluorescent material, forms white light, and the fluorescent material caloric value is little, improves the reliability of LED fluorescent tube.

Driving power is contained in connector 5 inside, for driving LED luminescence chip 1.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
