Description

LED straight lamp

Technical field

This utility model relates to field of lighting appliances, particularly relates to a kind of LED straight lamp.

Background technology

LED illumination technology is just fast-developing and instead of traditional electric filament lamp and fluorescent lamp.Compared to being filled with indifferent gas For the fluorescent lamp of body and hydrargyrum, LED straight lamp is without filling hydrargyrum.Therefore, various by seeming tradition fluorescent bulbs and lamp In the illuminator of the illumination domestic dominated of option such as pipe or working space, LED straight lamp is it is hardly surprising that be increasingly becoming people Height expect illumination option.The advantage of LED straight lamp comprises the ruggedness of lifting and life-span and relatively low power consuming.Therefore, After considering all factors, LED straight lamp would is that the illumination option of escapable cost.

LED straight lamp generally comprises substantial amounts of LED lamp component and drive circuit, and LED lamp component includes the envelope of LED chip Arrangement, light scattering assembly, high efficiency and heat radiation assembly, luminous reflectance and light diffusing board etc..LED lamp component and drive circuit heat dissipation capacity Very big, heat radiation is the principal element affecting LED lamp illumination intensity, if these heats do not have suitable emitting, The shinny degree of LED lamp and life-span will drastically decline.All the time, dispel the heat bad cause power supply damage, light decay accelerate, the life-span The problem such as shorten, be the key factor of LED illumination System performance boost all the time.LED luminous efficiency to be promoted and service life, solve Certainly LED product heat dissipation problem is one of present stage most important problem.

At present, the fluorescent tube major part of LED straight lamp is all to use plastics fluorescent tube, and heat radiation aspect is the most then to select metal material Expecting the material of the radiator as LED, fansink designs becomes to be exposed at outside fluorescent tube, although meeting improving radiating effect, but but The risk that will also result in user imprudence and get an electric shock；If fansink designs is all inside fluorescent tube, because LED lamp component is arranged The heat released still is deposited in radiator, and this heat retained can cause the plastics fluorescent tube used to become because of heat effect Shape.If LED straight lamp does not use metal material as the radiator of LED, the heat that LED lamp component is emitted also can make to mould Material fluorescent tube deforms because of heat effect.

It addition, fine aluminium radiator is the most most commonly seen radiator, but fine aluminium is too soft, it is impossible to meet hardness requirement, Radiator is all in the design within fluorescent tube, because the heat that LED lamp component is emitted can cause the plastics fluorescent tube used Deform because of heat effect, and fine aluminium radiator is unable to reach the function of support because of too soft.

Furthermore, control the brightness of LED and fluorescent lifetime though can pass through LED drive circuit and then reduce the heat of LED straight lamp Amount produces, and right LED luminance is then difficult to reach to expect corresponding brightness requirement.Furthermore, owing to being difficult to carry out with outside in fluorescent tube Thermal convection current even confined space, and the life-span of LED lamp bead is temperature sensitive, and brightness will also result in fluorescent tube while improving The shortening in service life.And between LED luminance and electric current and non-linear relation, if therefore controlling LED luminance with linear circuit, It is difficult to reach to expect corresponding brightness requirement, and the colour temperature of part LED also can change along with size of current.And known The type of drive of pulse width modulation (Pulse Width Modulation, PWM), as driving voltage and electric current are repeatedly Travel to and fro between minimum to making circuit bandwidth diminish between maximum, and then limit minimum turn-on cycle and affect driving The highest frequency of (light modulation).

Additionally, in existing LED straight lamp, the general side using plain conductor to pass through routing between rigid circuit board and lamp holder Formula realizes electrical connection, LED straight lamp manufacture, transport and use during, plain conductor routing is easily owing to moving Damage and even rupture, cause LED straight lamp to use.Or, the LED lamp component in fluorescent tube is through soft board circuit and lamp The power supply module electrical connection of head, therefore LED straight lamp is in the fabrication process, and the length of fluorescent tube is necessary for coordinating and considering soft board Circuit power factor, thus increase the uncertain factor that fluorescent tube manufacture process less easily controls.

It can be seen that current technique yet suffers from, heat conductivility is poor, radiating effect is the best, plastics fluorescent tube is easily heated change Shape, radiator expose easily electric shock, tube lamp holder electrical connection fragility, the electrical connection of fluorescent tube length limited lamp holder and drive circuit The defects such as control and bandwidth problem.

Refer to Figure 33 B, for the circuit box schematic diagram of the drive circuit according to this utility model the first preferred embodiment. Drive circuit comprises controller 1531 and change-over circuit 1532, carries out electric power conversion with the pattern of current source, to drive LED module Luminous.Change-over circuit 1532 comprises on-off circuit 1535 and accumulator 1538.It is defeated that change-over circuit 1532 couples the first filtering Go out end 521 and the second filtering output end 522, signal after accepting filter, and according to the control of controller 1531, be converted into driving letter Number and exported by the first drive output 1521 and the second drive output 1522, to drive LED module.At controller 1531 Under control, the driving signal that change-over circuit 1532 is exported is stabling current, and makes LED module stabilized illumination.

Refer to Figure 33 C, for the circuit diagram of the drive circuit according to this utility model the first preferred embodiment.At this Embodiment, drive circuit 1630 is decompression DC to-DC switching circuit, comprises controller 1631 and change-over circuit, and changes electricity Road comprises inductance 1632, fly-wheel diode 1633, electric capacity 1634 and switching switch 1635.Drive circuit 1630 couples the first filter Wave output terminal 521 and the second filtering output end 522, so that the filtered signal of reception is converted into driving signal, couple to drive LED module between the first drive output 1521 and the second drive output 1522.

In the present embodiment, switching switch 1635 is metal-oxide half field effect transistor, has control end, the first end and second End.First end of switching switch 1635 couples the positive pole of fly-wheel diode 1633, and the second end couples the second filtering output end 522, Control end couples controller 1631 to be made between the first end and the second end as on or off with the control accepting controller 1631.The One drive output 1521 couples the first filtering output end 521, and the second drive output 1522 couples one end of inductance 1632, and The other end of inductance 1632 couples the first end of switching switch 1635.Electric capacity 1634 be coupled to the first drive output 1521 and Between second drive output 1522, to stablize the electricity between the first drive output 1521 and the second drive output 1522 Pressure reduction.The negative terminal of fly-wheel diode 1633 couples the first drive output 1521.

Next the running of drive circuit 1630 is described.

When controller 1631 determines conducting and the cut-off of switching switch 1635 according to current sense signal S535 and/or S531 Between, the dutycycle (Duty Cycle) namely controlling switching switch 1635 regulates the size driving signal.Current sense is believed Number S535 system represents the size of current flowing through switching switch 1635.The representative of current sense signal S535 system flows through and is coupled to first and drives The size of current of the LED module between dynamic outfan 1521 and the second drive output 1522.According to current sense signal S531 And S535's is arbitrary, controller 1631 can obtain the information of the electric power size that change-over circuit is changed.When switching switch 1635 During conducting, the electric current of filtered signal is flowed into by the first filtering output end 521, and through electric capacity 1634 and the first drive output 1521 are flowed out by the second filtering output end 522 after LED module, inductance 1632, switching switch 1635.Now, electric capacity 1634 and Inductance 1632 carries out energy storage.When switching switch 1635 cut-off, inductance 1632 and electric capacity 1634 discharge stored energy, electric current LED module still continuous illumination is made to the first drive output 1521 through fly-wheel diode 1633 afterflow.
