Abstract
The invention relates to a flash lamp module which comprises a reflection umbrella and a lamp tube inserted in the reflection umbrella, wherein the reflection umbrella is provided with a light-reflecting surface and is made of conducting materials. At least one protuberant trigger electrode extends from the outer surface of the reflection umbrella to the direction away from the light-reflecting surface. By the electrical connection of the trigger electrode and a printed circuit board, the trigger electrode extends from the reflection umbrella, so that the contact between the flash lamp module and the printed circuit board can be well ensured, and the trigger electrode can also position the reflection umbrella without additional positioning structures, thereby lowering the manufacturing cost.
Description
Technical field
The present invention relates to a kind of flash lamp module.
Background technology
At present, in flash lamp module, during for the minimizing Welder, save to trigger and connect wire rod, make the modular structure miniaturization, often use flash lamp module 10 as shown in Figure 1, its fluorescent tube 11 is assembled into one with reflecting umbrella 12, reflecting umbrella 12 triggers shell fragment 13 with the Z font and contacts, and triggers shell fragment 13 lower ends and is electrically connected with a printed circuit board (PCB) (figure does not show).Printed circuit board (PCB) produces the high pressure of 3K～5K, trigger shell fragment 13 usefulness touching modes by the Z font and conduct to reflecting umbrella 12, utilize the gas in the energy excitation fluorescent tube 11 of instantaneous pressure then, make this gas ionizationization, 11 two ends moment conductings produce flash of light to the voltage difference that the two ends of fluorescent tube 11 have because the gas in the fluorescent tube 11 is made fluorescent tube by freeization.But this flash lamp module 10 because of the Z font triggers the weak or skew of shell fragment 13 elasticity, can cause and reflecting umbrella 12 loose contacts, even cause the problem that can't trigger in the electrical conduction process.
In addition, reflecting umbrella and printed circuit board (PCB) also have bonding realization the by the Copper Foil that has conducting resinl to be connected, so just also will be outside conducting resinl subsides one deck insulating tape.
In the above-mentioned dual mode, first kind of mode causes loose contact easily, the second way needs extra parts to realize being connected of reflecting umbrella and printed circuit board (PCB), and the location of dual mode reflecting umbrella all needs other location structure, so has increased production cost.
Summary of the invention
In view of this, be necessary to provide a kind of contact good and lower-cost flash lamp module.
A kind of flash lamp module, it comprises a reflecting umbrella and a fluorescent tube that is inserted on the described reflecting umbrella.Described reflecting umbrella has a reflective surface.Described reflecting umbrella adopts conductive material to make.From the outer surface of described reflecting umbrella to the trigger electrode that extends at least one overshooting shape away from the direction of described reflective surface.
With respect to prior art, described flash lamp module, extend the trigger electrode of at least one overshooting shape from the outer surface of described reflecting umbrella, and by described trigger electrode and printed circuit board (PCB) electric connection, because described trigger electrode extends out from described reflecting umbrella, so can guarantee to contact between described flash lamp module and the printed circuit board (PCB) good, and this trigger electrode also can play the effect with described reflecting umbrella location, do not need other location structure, so reduced production cost.
Description of drawings
Fig. 1 is the structural representation of existing flash lamp module.
Fig. 2 is the schematic perspective view of flash lamp module of the present invention.
The specific embodiment
For flash lamp module of the present invention is described further, lifts following embodiment and conjunction with figs. and be elaborated as follows.
See also Fig. 2, flash lamp module 100 provided by the invention comprises a reflecting umbrella 110 and a fluorescent tube 120 that is inserted on the described reflecting umbrella 110.Described flash lamp module 100 is connected with a printed circuit board (PCB) 200.
Described reflecting umbrella 110 has an exiting surface 111 and a reflective surface 112.Wherein, described reflective surface 112 is the inner surface of described reflecting umbrella 110.The outer surface 113 of described reflecting umbrella 110 is to the trigger electrode 130 that extends at least one overshooting shape away from the direction of described reflective surface 112.
The direction that described trigger electrode 130 extends can be for arbitrarily, and in the present embodiment, described trigger electrode 130 is vertical with described exiting surface 111.So be provided with, can make described reflecting umbrella 110 easier with described printed circuit board (PCB) 200 assemblings.
Described trigger electrode 130 can be positioned at the optional position of the outer surface 113 of described reflecting umbrella 110, and in the present embodiment, described trigger electrode 130 is positioned at an end of described reflecting umbrella 110.So be provided with, moulding is easier to.Be appreciated that described trigger electrode 130 also can be positioned at central authorities or other positions of the outer surface 113 of described reflecting umbrella 110.
Described trigger electrode 130 can directly insert described printed circuit board (PCB) 200, described trigger electrode 130 is formed with described printed circuit board (PCB) 200 electrically connect.In the present embodiment, described trigger electrode 130 directly inserts described printed circuit board (PCB) 200.So be provided with, easily assembling.
A kind of in the figure that the arc shape of the cross section of described reflecting umbrella 110 can be is parabola shaped, half elliptic, semicircle or other camber lines form, the cross section of reflecting umbrella 110 is parabola shaped in the present embodiment.Described reflecting umbrella 110 adopts conductive material to make, and preferably, described reflecting umbrella 110 adopts metal material to make.
Inflation body in the described fluorescent tube 120, when described flash lamp module 100 is worked, described trigger electrode 130 produces instantaneous pressure, and send gas in the described fluorescent tube 120 to via described reflecting umbrella 110, thereby described gas is ionized, and ionized gas presents low-impedance state, makes the negative electrode and the anode conducting of described fluorescent tube 120, this moment, a large amount of electric currents were by making the moment conducting of 120 liang of terminal circuits of fluorescent tube, thereby realized flash of light.
Above-mentioned flash lamp module, extend the trigger electrode of at least one overshooting shape from the outer surface of described reflecting umbrella, and by described trigger electrode and the electric connection of described printed circuit board (PCB), because described trigger electrode extends out from described reflecting umbrella, so can guarantee to contact between described flash lamp module and the described printed circuit board (PCB) well, and this trigger electrode also can play the effect with described reflecting umbrella location, does not need other location structure, so reduced production cost.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
