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

Flash lamp module

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 as shown in Figure 1 10, 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 through 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 conductivity process.

In addition, reflecting umbrella and printed circuit board (PCB) also have bonding realization the through 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 additional 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, has therefore 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 is connected with a printed circuit board (PCB), and said flash lamp module comprises a reflecting umbrella and a fluorescent tube that is inserted on the said reflecting umbrella.Said reflecting umbrella has a reflective surface.Said reflecting umbrella adopts conductive material to process.The outside surface of said reflecting umbrella extends the trigger electrode of at least one overshooting shape away from the direction of said reflective surface, and said trigger electrode directly links to each other with said printed circuit board (PCB) so that said reflecting umbrella and said printed circuit board (PCB) are electrical connected.

With respect to prior art, said flash lamp module is extended the trigger electrode of at least one overshooting shape from the outside surface of said reflecting umbrella; And through said trigger electrode and printed circuit board (PCB) electric connection; Because said trigger electrode extends out from said reflecting umbrella, so can guarantee to contact between said flash lamp module and the printed circuit board (PCB) good, and this trigger electrode also can play the effect with said reflecting umbrella location; Do not need other location structure, so reduced production cost.

Fig. 2 is the schematic perspective view of flash lamp module of the present invention.

Embodiment

For flash lamp module of the present invention is done further explanation, lift 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 said reflecting umbrella 110.Said flash lamp module 100 is connected with a printed circuit board (PCB) 200.

Said reflecting umbrella 110 has an exiting surface 111 and a reflective surface 112.Wherein, said reflective surface 112 is the inside surface of said reflecting umbrella 110.The outside surface 113 of said reflecting umbrella 110 is to the trigger electrode 130 that extends at least one overshooting shape away from the direction of said reflective surface 112.

The direction that said trigger electrode 130 extends can be for arbitrarily, and in this embodiment, said trigger electrode 130 is vertical with said exiting surface 111.So be provided with, can make said reflecting umbrella 110 easier with said printed circuit board (PCB) 200 assemblings.

Said trigger electrode 130 can be positioned at the optional position of the outside surface 113 of said reflecting umbrella 110, and in this embodiment, said trigger electrode 130 is positioned at an end of said reflecting umbrella 110.So be provided with, moulding is easier to.Be appreciated that said trigger electrode 130 also can be positioned at central authorities or other positions of the outside surface 113 of said reflecting umbrella 110.

Said trigger electrode 130 can directly insert said printed circuit board (PCB) 200, said trigger electrode 130 is formed with said printed circuit board (PCB) 200 electrically connect.In this embodiment, said trigger electrode 130 directly inserts said printed circuit board (PCB) 200.So be provided with, easily assembling.

A kind of in the figure that the arc shape of the xsect of said reflecting umbrella 110 can be is parabola shaped, half elliptic, semicircle or other camber lines form, the xsect of reflecting umbrella 110 is parabola shaped in this embodiment.Said reflecting umbrella 110 adopts conductive material to process, and preferably, said reflecting umbrella 110 adopts metal material to process.

Inflation body in the said fluorescent tube 120, when said flash lamp module 100 was worked, said trigger electrode 130 produced instantaneous pressures; And send the gas in the said fluorescent tube 120 to via said reflecting umbrella 110; Thereby said gas is by ionization, and ionized gas presents low-impedance state, makes the negative electrode and the anode conducting of said fluorescent tube 120; This moment, a large amount of electric currents were through 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 outside surface of said reflecting umbrella, and pass through said trigger electrode and the electric connection of said printed circuit board (PCB), because said trigger electrode extends out from said reflecting umbrella; So can guarantee to contact between said flash lamp module and the said printed circuit board (PCB) well; And this trigger electrode also can play the effect with said reflecting umbrella location, does not need other location structure, so reduced production cost.

It is 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.
