Figure 32 is please referred to, Figure 32 is with Fig. 1's -4 the difference is that LED lamp panel 200 and the power supply circuit board 420 of 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 power supply circuit board 420 of the plane that the LED lamp panel 200 of Figure 32 is located at and power supply 400 is located at 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 are 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, using the axle center of fluorescent tube 100 as From the point of view of rotation center, the power supply circuit board 420 of power supply 400 is angle, θ 2 relative to the rotation angle of LED lamp plates 200, is passed through The plane that the power supply circuit board 420 of the plane that LED lamp panel 200 is located at and power supply 400 is located at is interlaced with each other and nonparallel Structure when hot gas caused by LED lamp panel 200 and LED light source 202 flows to lamp cap 300 by fluorescent tube 100, can smoothly lead to The power supply 400 to interlock with LED lamp plates 200 is crossed, and the external world is further flowed to by hole 320, is conducive to the promotion of heat dissipation effect.

Figure 33 is please referred to, Figure 33 is with Fig. 1's -4 the difference is that 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 caps 300 To the both ends of fluorescent tube 100.If one of lamp cap 300 has been assembled to wherein one end of fluorescent tube 100, and another lamp cap 300 is just When being assembled into the other end of fluorescent tube 100, since the inside of fluorescent tube 100 at this time belongs to the space of closing or approximate closing, it is present in Fluorescent tube 100 and the gas of the inner space of lamp cap 300 increase because of being compressed internal pressure.When internal pressure increases Added-time, assembler are needed that lamp cap 300 could be assembled on fluorescent tube 100 using the strength of bigger, can so caused in assembling Difficulty.And the hole 320 of Figure 33 can then be used as pressure-releasing hole, during lamp cap 300 is assembled into fluorescent tube 100, be present in lamp Pipe 100 and the gas of the inner space of lamp cap 300 can be disengaged by hole 320, tie up fluorescent tube 100 and the internal pressure of lamp cap 300 It holds constant, is so conducive to the assembling operation of LED straight lamps 50, efficiency when assembled can be improved.On the other hand, if lamp cap 300 There is no any hole, the fluorescent tube 100 of LED straight lamps 50 can become negative with the pressure inside lamp cap 300 because of the reduction of temperature Pressure, the hole 320 as relief passage allow extraneous gas to may flow into fluorescent tube 100 with lamp cap 300 so that fluorescent tube 100 and lamp cap 300 internal pressure can maintain constant (equal with the external pressure of lamp cap 300 with fluorescent tube 100), thus in LED straight lamps 50 In disassembly process, lamp cap 300 can be easily by disassembling on fluorescent tube 100.

In addition to this, when LED straight lamps 50 work, internal electronic component can generate thermal energy, make LED straight lamps 50 internal temperature raising.According to ideal gas equation, when the temperature increases, gas volume inside LED straight lamps 50 with The product of pressure can increase, if but gas is when being closed in the inside of fluorescent tube 100 and lamp cap 300, this represents the volume of gas It is fixed, therefore, as gas temperature increases, pressure can also increase, this is represented when LED 50 continuous firings of straight lamp, Internal electronic component needs to bear high temperature and high pressure for a long time, will so reduce the service life of electronic component.And the hole of Figure 33 Hole 320 then has the function of release of pressure, that is to say, that when the gas temperature inside LED straight lamps 50 increases, the gas of expansion can It is disengaged by hole 320, so can effectively reduce the pressure inside LED straight lamps 50.

Please refer to Figure 34, Figure 34 is sectional views of the Figure 33 on D-D ' directions, Figure 34 and Figure 33's the difference is that, Figure 34's LED straight lamps 50 further include optical inductor 450 and switch (not shown) with circuit safety.In the present embodiment, optical inductor 450, Circuit safety switch is electrically connected on the power supply circuit board 420 of power supply 400 and with the power supply circuit board 420 of power supply 400, but It is without being limited thereto.Also, power supply 400 can built-in power supply source, such as power supply 400 can built-in minicell, thereby, in LED straight tubes In the case that lamp 50 is not yet installed on lamp holder, 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.Optical inductor 450 is aligned hole 320.In different embodiments, optical inductor 450 can not It extends among hole 320；Alternatively, optical inductor 450 may extend among hole 320, thereby, optical inductor 450 can sense Except brightness among hole 320 or sensing hole 320 but the ambient brightness near end wall 302.Also, optical inductor 450 can generate corresponding sensing signal according to the brightness sensed, and the sensing signal can be transferred into the circuit peace Full switch, and circuit safety switch can determine whether to allow according to the sensing signal received the circuit turn-on of power supply 400 Or open circuit.

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

For example, when user hand holds LED straight lamps 50, LED straight lamps 50 are installed on lamp holder 60 by preparation (please be same When with reference to Figure 19-21) on, at this time because the lamp cap 300 at the both ends of LED straight lamps 50 is all to expose to the open air in the environment and be not affected by The state of masking, therefore the brightness that the optical inductor 450 in two lamp caps 300 is sensed can all be more than specific threshold, it is described Circuit safety switch can allow the circuit breaker of power supply 400.Then, when user is by the sky of the lamp cap 300 of one end of LED straight lamps 50 When heart conductive pin 310 is inserted into the conductive trough 61 of one end of lamp holder 60, the light sensation in the lamp cap 300 of the one end for being already inserted into lamp holder 60 It answers device 450 that can be covered by lamp holder 60, therefore its brightness sensed can all be less than specific threshold, but is not yet inserted into lamp holder 60 Another lamp cap 300 in the brightness that is sensed of optical inductor 450 still greater than specific threshold, therefore the circuit safety is opened Closing can still allow the circuit of power supply 400 to maintain open circuit.Thus, user does not have the risk of electric shock.Finally, when user is by LED After straight lamp 50 is appropriately mounted at lamp holder 60, the lamp cap 300 at the both ends of LED straight lamps 50 is all covered by lamp holder 60, two lamp caps The brightness that optical inductor 450 in 300 is sensed can all be less than specific threshold, in this situation, the circuit safety switch The circuit turn-on of power supply 400 can just be allowed, power supply 400 can just receive the electric power from lamp holder 60, and supply power to LED light Plate 200 and LED light source 202.

The optical inductor 450 of 4 LED straight lamps 50 is switched with circuit safety according to fig. 3, in one end of LED straight lamps 50 The hollow conductive pin 310 of lamp cap 300 be already inserted into the conductive trough 61 of lamp holder 60, and the hollow conduction of the lamp cap 300 of the other end In the case that needle 310 still exposes to the open air in the environment, even if the hollow conductive pin 310 exposed to the open air is accessible to user, but due to the electricity Road safety switch can allow the circuit breaker (or maintain open circuit) of power supply 400 automatically, so user does not have the risk of electric shock.By This, safety of the LED straight lamps 50 on using is increased.
