Abstract
The utility model mainly discloses a placing structure of an LED (light-emitting diode) lamp tube lighting circuit, which comprises a lamp panel with an LED lamp and a lamp tube, wherein a circuit board comprises a rectifying filter circuit board and a constant current driving circuit board; and the rectifying filter circuit board and the constant current driving circuit board are respectively welded and fixed at both tail ends of a panel. The placing structure of the LED lamp tube lighting circuit is beneficial to heat dissipation of the LED lamp in the working process, is difficult to age and has long service life.
Description
Technical field
The utility model relates to the LED tube circuit, and especially to lay structure relevant with LED fluorescent tube lighting circuit.
Background technology
Existing LED lamp tube structure such as Fig. 1, Fig. 2, shown in Figure 3 lay required LED lamp 20 on lamp plate 10, be example with SMD, and the drive circuit of LED fluorescent tube is independently to be installed in circuit board 30, mainly comprises current rectifying and wave filtering circuit and constant-current drive circuit.Then circuit board 30 fixedly is attached to the back side of lamp plate 10, last lamp plate 10 is put into fluorescent tube 40 together with circuit board 30, has the draw-in groove 50 that fixes lamp plate 10 on fluorescent tube 40 inwalls, and fluorescent tube 40 two are loaded onto lamp tube joint 60 and got final product.
The existing LED fluorescent tube of this type, because circuit board 30 is to be fitted on the lamp plate 10, it is bad to dispel the heat when causing 20 work of LED lamp, the heat of generation is accumulated.After using a period of time, LED lamp 20, LED lamp 20 easy ageing that particularly contact with circuit board 30, brightness is decay ahead of time, greatly reduction of service life.
To above-mentioned defective, the inventor designs a kind of structure of laying of LED illuminating lamp tube drive circuit, and this case produces thus.
The utility model content
The purpose of the utility model just provides a kind of structure of laying of LED illuminating lamp tube drive circuit, and heat radiation when this structure helps the work of LED lamp is difficult for wearing out long service life.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of LED illuminating lamp tube drive circuit board lay structure; Comprise lamp plate, fluorescent tube, drive circuit board that the LED lamp is installed; Wherein drive circuit board comprises current rectifying and wave filtering circuit plate and constant-current drive circuit plate; Solid welding is at two ends of lamp plate respectively for current rectifying and wave filtering circuit plate and constant-current drive circuit plate, and lamp plate is installed in the fluorescent tube.
Described fluorescent tube external power supply advances lead and acts on the current rectifying and wave filtering circuit plate, and the dc source that current rectifying and wave filtering circuit obtains causes on the constant-current drive circuit plate, the LED lamp work on the driving LED lamp plate.
Total length after described current rectifying and wave filtering circuit plate, constant-current drive circuit plate and lamp plate are installed meets the length that fluorescent tube can hold.
After adopting such scheme; The utility model is because two circuit boards all are the ends that is welded on lamp plate; Rather than be fitted on the lamp plate, the heat that has solved the generation when work of LED lamp can't in time be waved diffusing problem, has overcome the overheated early ageing of LED lamp; Increase the service life, practice thrift use cost virtually.Do not influence simultaneously the efficient of circuit to LED lamp body driving work.

Fig. 7 is the circuit diagram two of the utility model preferred embodiment.
The specific embodiment
In conjunction with accompanying drawing, the utility model is further specified.
Like Fig. 4, shown in Figure 5, the utility model mainly is the drive circuit with the LED lamp, is divided into independently current rectifying and wave filtering circuit plate 1 and 2 two parts of constant-current drive circuit plate.Current rectifying and wave filtering circuit plate 1 and constant-current drive circuit plate 2 are welded on two ends of lamp plate 3 respectively; Become the extension component at lamp plate 3 two ends; Lamp plate 3 fronts are equipped with required LED lamp 5, and LED lamp 5 is patch form in the present embodiment, also are applicable to the LED lamp of other types certainly.
The concrete operation principle of current rectifying and wave filtering circuit plate 1 and constant-current drive circuit plate 2 is referring to Fig. 6; At first; The illumination AC power is connected on current rectifying and wave filtering circuit plate 1 and the constant-current drive circuit plate 2 through two circuits of external plug 4, and the power supply that is connected on the constant-current drive circuit plate 2 is guided to current rectifying and wave filtering circuit plate 1 through separate lines on the lamp plate 3.AC power obtains required dc source through behind the rectifying and wave-filtering, receives constant-current drive circuit plate 2 through circuit then, produces the voltage ± DC that is fit to the driving LED lamp by constant-current drive circuit plate 2, is connected on the lamp plate 3 by lead then.
Fig. 7 is the another kind of embodiment of Fig. 6, and principle is identical, the difference that just do not connect up, thereby make ± DC is in the opposite direction.
In the utility model; The length of lamp plate 3 is shorter than existing lamp plate length; Purpose is to reserve the space that current rectifying and wave filtering circuit plate 1 and constant-current drive circuit plate 2 can be installed for two, guarantee that current rectifying and wave filtering circuit plate 1, constant-current drive circuit plate 2 and lamp plate 3 assembling back overall length are the length that fluorescent tube can hold.Because in current rectifying and wave filtering circuit plate 1 and constant-current drive circuit plate 2 actual fabrication, length is compared lamp plate 3 and will be lacked a lot, so do not influence lamp plate 3 brightness effects.
The current rectifying and wave filtering circuit plate 1 that welding is good and constant-current drive circuit plate 2 refill two lamp tube joints 60 and get final product along with in the draw-in groove 50 in lamp plate 3 the is installed to LED fluorescent tube shown in Figure 2.
Because circuit board is arranged on two ends of lamp plate 3, rather than is attached on the LED lamp, reserved sufficient heat-dissipating space for the LED lamp, so the utility model has solved the problem of the overheated early ageing of LED fluorescent tube.
