In addition, the difference of Figure 30 and Figure 29 is also resided in, and the lamp holder 300 of Figure 30 also includes baffle plate 350, baffle plate 350 in the interior sidewall surface of side wall 301, and baffle plate 350 is spaced with end wall 302 in the axial direction of side wall 301.Its In, the side contactor banking stop plate 350 of the power supply circuit board 420 of power supply 400 towards end wall 302.By baffle plate 350, power supply 400 Power supply circuit board 420 and end wall 302 between can keep gap, this gap can allow gas to circulate, be conducive to carrying for radiating effect Rise.

The difference that refer to Figure 31, Figure 31 and Figure 29 is that the horizontal rib 340 of Figure 29 is whole piece, and the water of Figure 31 Flat rib 340 then has perforate.Specifically, each horizontal rib 340 of Figure 31 includes multiple pod apertures 344, pod apertures 344 run through horizontal rib 340 and are arranged in horizontal rib 340.Pod apertures 344 can allow gas to circulate, and be conducive to radiating effect Lifting.

The difference that refer to Figure 32, Figure 32 and Fig. 1-4 is the power supply circuit board 420 of LED lamp panel 200 and power supply 400 Relativeness.The plane that the plane that the LED lamp panel 200 of Fig. 1-4 is located at is located at power supply 400 is generally parallel to each other , the plane that the plane that the LED lamp panel 200 of Figure 32 is located at is located at the power supply circuit board 420 of power supply 400 is not then each other Parallel.Specifically, as shown in figure 32, LED lamp panel 200 is located on the first plane P1, the power supply circuit board 420 of power supply 400 On the second plane P2, the first plane P1 and the second plane P2 is substantially parallel to the axial direction of fluorescent tube 100, and the first plane P1 Angle, θ 2 is accompanied with the second plane P2, angle, θ 2 is more than 0 degree and less than or equal to 90 degree.In other words, it is with the axle center of fluorescent tube 100 From the point of view of pivot, the power supply circuit board 420 of power supply 400 is angle, θ 2 relative to the anglec of rotation of LED lamp panel 200, by LED The plane knot interlaced with each other and nonparallel that the plane that lamp plate 200 is located at is located at the power supply circuit board 420 of power supply 400 Structure, when the hot gas produced by LED lamp panel 200 and LED light source 202 flows to lamp holder 300 by fluorescent tube 100, can smoothly pass over The power supply 400 interlocked with LED lamp panel 200, and the external world further flowed to by hole 320, be conducive to the lifting of radiating effect.

The difference that refer to Figure 33, Figure 33 and Fig. 1-4 is the kenel of hole 320.The hole 320 of Figure 33 is located at end wall 302 center, but not limited to this.In the assembling process of LED straight lamps 50, assembler needs to assemble in two lamp holders 300 To the two ends of fluorescent tube 100.If one of lamp holder 300 has been assembled to wherein one end of fluorescent tube 100, and another lamp holder 300 is just When being assembled into the other end of fluorescent tube 100, the space of closing or approximate closing is belonged to due to the inside of now fluorescent tube 100, be present in Fluorescent tube 100 can make the pressure increase of inside with the gas of the inner space of lamp holder 300 because of being compressed.When internal pressure increases When, assembler needs to use the bigger strength lamp holder 300 could be assembled on fluorescent tube 100, can so cause in assembling It is difficult.And the hole 320 of Figure 33 then can be present in fluorescent tube as pressure-releasing hole, during lamp holder 300 is assembled into fluorescent tube 100 100 can be disengaged with the gas of the inner space of lamp holder 300 by hole 320, fluorescent tube 100 is maintained with the internal pressure of lamp holder 300 It is constant, be so conducive to the assembling operation of LED straight lamps 50, efficiency during assembling can be improved.On the other hand, if lamp holder 300 does not have Fluorescent tube 100 and the pressure inside lamp holder 300 for having any hole, LED straight lamps 50 can become negative pressure because of the reduction of temperature, Extraneous gas is allowed to may flow into fluorescent tube 100 with lamp holder 300 as the hole 320 of relief passage so that fluorescent tube 100 and lamp holder 300 Internal pressure can maintain constant (equal with the external pressure of lamp holder 300 with fluorescent tube 100), thus in the dismounting of LED straight lamps 50 During, lamp holder 300 can easily by being disassembled on fluorescent tube 100.

In addition, when LED straight lamps 50 work, its internal electronic component can produce heat energy, make LED straight lamps 50 Internal temperature raise.According to ideal gas equation, when the temperature increases, gas volume and pressure inside LED straight lamps 50 The product of power can increase, if but gas when being the inside for being closed in fluorescent tube 100 and lamp holder 300, this represents that the volume of gas is Fixed, therefore, as gas temperature is raised, pressure can also increase, and this is represented when LED 50 continuous firings of straight lamp, in it The electronic component in portion needs to bear high temperature and high pressure for a long time, will so reduce the life-span of electronic component.And the hole of Figure 33 320 functions with release of pressure, that is to say, that during gas temperature rising when LED straight lamps 50 inside, the gas of expansion can be by Hole 320 disengages, and so can effectively reduce the pressure inside LED straight lamps 50.

Figure 34 is refer to, Figure 34 is profiles of the Figure 33 on D-D ' directions, the difference of Figure 34 and Figure 33 is, Figure 34's LED straight lamps 50 also include optical inductor 450 with circuit safety switch (not shown).In the present embodiment, optical inductor 450, Circuit safety switch is electrically connected with the power supply circuit board 420 of power supply 400 and with the power supply circuit board 420 of power supply 400, but Not limited to this.Also, power supply 400 can it is built-in power supply source, for example power supply 400 can built-in minicell, thereby, in LED straight tubes In the case that lamp 50 is not yet installed on lamp socket, power supply 400 also can obtain electric power by minicell, with supply optical inductor 450 with Needed for the running of the circuit safety switch.Wherein, the circuit safety switch is integrated in inside power supply 400, and optical inductor 450 are set corresponding to hole 320.The alignment hole 320 of optical inductor 450.In different embodiments, optical inductor 450 can not Extend among hole 320；Or, optical inductor 450 be may extend among hole 320, and thereby, optical inductor 450 can be sensed Outside brightness among hole 320 or sensing hole 320 but the ambient brightness near end wall 302.Also, optical inductor 450 can produce corresponding sensing signal according to the brightness for being sensed, and the sensing signal can be transferred into the circuit pacifies Full switch, and circuit safety switch can determine whether to allow the circuit turn-on of power supply 400 according to the sensing signal for being received Or open circuit.

Optical inductor 450 is for example following with the function mode that circuit safety is switched, but not limited to this：When any one lamp holder 300 In the brightness that is sensed of optical inductor 450 when being more than or equal to specific threshold, the circuit safety switch can allow power supply 400 Circuit breaker；And when the brightness both less than specific threshold that the optical inductor 450 in two lamp holders 300 is sensed, it is described Circuit safety switch can just allow the circuit turn-on of power supply 400.

For example, when user it is hand-held LED straight lamps 50, LED straight lamps 50 are installed on lamp socket 60 by preparation (please be same When reference picture 19-21) on, now because LED straight lamps 50 two ends lamp holder 300 be all expose to the open air in the environment and be not affected by hide The brightness that optical inductor 450 in the state covered, therefore two lamp holders 300 is sensed can all be more than specific threshold, the electricity Road safety switch can allow the circuit breaker of power supply 400.Then, when user is by the hollow of the lamp holder 300 of one end of LED straight lamps 50 During the conductive trough 61 of one end of the insertion lamp socket 60 of conductive pin 310, the photoinduction in the lamp holder 300 of one end of lamp socket 60 is already inserted into Device 450 can be covered by lamp socket 60, therefore its brightness for being sensed all less than specific threshold, but can not yet insert lamp socket 60 The brightness that optical inductor 450 in another lamp holder 300 is sensed is switched still greater than specific threshold, therefore the circuit safety The circuit of power supply 400 can be still allowed to maintain open circuit.Consequently, it is possible to user does not have the risk of electric shock.Finally, when user is straight by LED After spot 50 is appropriately mounted at lamp socket 60, the lamp holder 300 at the two ends of LED straight lamps 50 is all covered by lamp socket 60, two lamp holders 300 In the brightness that is sensed of optical inductor 450 all can be less than specific threshold, in this situation, the circuit safety switchs just meeting Allow the circuit turn-on of power supply 400, power supply 400 can just receive the electric power from lamp socket 60, and supply power to LED lamp panel 200 With LED light source 202.

The optical inductor 450 of the LED straight lamps 50 according to Figure 34 is switched with circuit safety, in one end of LED straight lamps 50 The hollow conductive pin 310 of lamp holder 300 be already inserted into the conductive trough 61 of lamp socket 60, and the hollow conduction of the lamp holder 300 of the other end In the case that pin 310 still exposes to the open air in the environment, though the hollow conductive pin 310 for exposing to the open air is accessible to user, but due to the electricity Road safety switch can automatically allow the circuit breaker (or maintain open circuit) of power supply 400, so user does not have the risk of electric shock.By This, LED straight lamps 50 are increased using upper security.

Figure 35 to Figure 38 is refer to, Figure 35 is the power supply of LED lamp panel 200 (such as bendable circuit soft board) and power supply 400 The schematic diagram of attachment structure between circuit board 420, Figure 36 to Figure 38 is the power supply circuit board 420 of LED lamp panel 200 and power supply 400 Connection procedure schematic diagram.In the present embodiment, LED lamp panel 200 and freedom portion 210 are identical structure, and freedom portion 210 is The part for connecting power supply circuit board 420 of the opposite end of LED lamp panel 200.LED lamp panel 200 is bendable circuit soft board, And LED lamp panel 200 includes the circuit layer 200a and circuit protecting layer 200c of stacking.
