Description
Technical field
The utility model relates to a kind of light fixture, particularly a kind of LED fluorescent lamp.
Background technology
Traditional fluorescent lamp is widely used in daily life, but power consumption height, energy-conserving and environment-protective consciousness raising day by day along with people, the LED energy-saving daylight lamp that can match with the traditional fluorescent lamp lamp socket has appearred, such as Chinese patent publication number CN2926767Y discloses a kind of LED fluorescent lamp, comprises fluorescent tube, carries the circuit for lamp plate, is located at the some LED light emitting diodes that carry circuit for lamp plate one side, the opposite side power circuit of being located at year circuit for lamp plate.Wherein, be provided with the corresponding fluorescent tube of a side of LED light emitting diode and partly be transparent shell,, have the too dazzling problem of LED fluorescent lamp light because LED is that spot light, light are too strong with carrying lamp body; And,, the trickle decorative pattern on the tube wall is cast out produce the shadow phenomenon easily because LED is a direct light; In addition, components and parts are located at the same side of carrying the circuit for lamp plate in the power circuit, and the constant current IC in the power circuit can produce other metal components and parts and disturb, and causes the power circuit instability easily, and the phenomenon of flicker appears in the LED fluorescent lamp.
The utility model content
The purpose of this utility model is to provide a kind of LED fluorescent lamp, and the light that existing LED fluorescent lamp exists is too dazzling to overcome, problems such as shadow and flicker appear in light-emitting area.
For achieving the above object, the utility model adopts following technical scheme: a kind of LED fluorescent lamp, comprise fluorescent tube, circuit substrate, a plurality of LED light emitting diode that is arranged on circuit substrate one side, be arranged on the power circuit of circuit substrate opposite side and be positioned at lamp tube ends, the lamp base that can match with lamp socket, wherein, the described tube inner wall corresponding circuits substrate side that has the LED light emitting diode is provided with one or more layers PET (PET) film.Described PET film is PET diffusion barrier or PET bright enhancement film; Also can be that two kinds of materials use simultaneously.
Also comprise a constant current IC in the described power circuit, described constant current IC is arranged on the side that circuit substrate has the LED light emitting diode.
The side that described tube inner wall corresponding circuits substrate has power circuit is provided with concavo-convex striped.
Described tube inner wall vertically is provided with a pair of strip draw-in groove, and circuit substrate is fixed in the fluorescent tube by draw-in groove.
LED light emitting diode one side that is provided with of described circuit substrate is coated with reflectorized material.
Described reflectorized material is white oil (a liquid photosensitive welding resistance printing ink).
Described circuit substrate is a pcb board.
Described fluorescent tube is the PC pipe.
The beneficial effects of the utility model are: it is soft, not dazzling, unshadowed to use light, and illuminating effect is stable.

The specific embodiment
With embodiment the utility model is described further with reference to the accompanying drawings below:
Extremely shown in Figure 2 as Fig. 1, a kind of LED fluorescent lamp 1, comprise fluorescent tube 2, circuit substrate 3, a plurality of LED light emitting diode 4 that is arranged on circuit substrate 3 one sides, be arranged on the power supply 5 of circuit substrate 3 opposite sides and be positioned at fluorescent tube 2 two ends, the lamp base that can match (meaning not shown in the figures) with daylight lamp holder.Because LED is the too dazzling problem of light that spot light, light cause too by force, the side that described fluorescent tube 2 inwall corresponding circuits substrates 3 have LED light emitting diode 4 is provided with one or more layers of PET (PET) film 6 in order to solve.Owing to adopted PET film 6, the high light of LED light emitting diode 4 spot lights is decomposed, and it is very soft that light becomes; Simultaneously, original occur easily since the shadow phenomenon that LED light emitting diode 4 direct lights cast out the trickle decorative pattern on fluorescent tube 2 tube walls do not existed because of the decomposition of 6 pairs of LED light emitting diode 4 direct projection high lights of PET film yet.In the utility model, fluorescent tube 2 adopts the PC pipe, circuit substrate 3 adopts pcb board, PET film 6 can adopt the PET diffusion barrier separately, also can adopt the PET bright enhancement film separately, strengthen illuminating effect again when making LED fluorescent lamp light soft, also can use PET diffusion barrier and PET bright enhancement film simultaneously.
Also include a constant current IC 8 in the LED fluorescent lamp 1 in the power supply 5, generally constant current IC8 is contained in circuit substrate 3 the same sides with other power supply metal components and parts, because constant current IC 8 can produce other metal components and parts and disturb, cause power supply 5 instabilities easily, the phenomenon of flicker appears in LED fluorescent lamp 1.In order to eliminate the interference of constant current IC 8 to other metal components and parts, the utility model is about to the side that is provided with LED light emitting diode 4 that constant current IC 8 is arranged on circuit substrate 3 to constant current IC 8 anti-dresses.Like this, LED fluorescent lamp 1 in use, there is not interference in constant current IC 8 over against the air of clear, thereby avoided the phenomenon of LED fluorescent lamp 1 flicker.
For the dazzle of passing through inside that prevents that LED fluorescent lamp 1 from producing in when work, have a side of power supply 5 at described fluorescent tube 2 inwall corresponding circuits substrates 3, be provided with concavo-convex striped 9.Owing to be provided with concavo-convex striped 9, not only decompose the dazzle of passing through inside, and blocked the power circuit part of LED fluorescent lamp 1 inside, make LED fluorescent lamp 1 more attractive in appearance.
For better permanent circuit substrate 3, vertically be provided with a pair of strip draw-in groove 7 at described fluorescent tube 2 inwalls, circuit substrate 3 is fixed in the fluorescent tube 2 by draw-in groove 7.
For the luminous energy of the LED light emitting diode 4 of better utilization, described circuit substrate 3 is coated with reflectorized material in a side of LED light emitting diode 4 light-emitting areas, and described reflectorized material is white oil (a liquid photosensitive welding resistance printing ink).
In actual the use, in the lamp socket of the traditional fluorescent lamp of only the utility model LED fluorescent lamp need being packed into, can replace traditional fluorescent lamp to use.
Adopted the LED fluorescent lamp of technical solutions of the utility model, used not only energy-conserving and environment-protective, and light is soft, stable.Can replace traditional fluorescent lamp widely.
