Description

Flash lamp module

Technical field

The present invention relates to a kind of flash lamp module, relate in particular to a kind of flash lamp module that triggers the energy loss that reduces.

Background technology

At present, in flash lamp module, during for the minimizing Welder, save and trigger the connection wire rod, make the modular structure miniaturization, often use module shown in Figure 1 100, speedlight 110 has a style of one's own with reflecting umbrella 120, utilize structural orientation to make reflecting umbrella 120 and Z font trigger shell fragment 130 and contact, contact point is 131, triggers shell fragment 130 lower ends and is electrically connected with a printed circuit board (PCB).Printed circuit board (PCB) produces the high pressure of 3K ~ 5K, nationality triggers shell fragment 130 usefulness touching modes by the Z font and conducts to reflecting umbrella 120, utilize the gas in the energy excitation speedlight 110 of instantaneous pressure then, make its freeization, 110 two ends moment conductings produce flash of light to the voltage difference that the two ends of speedlight 110 have because the gas in the speedlight 110 is made speedlight by freeization.But this flash lamp module 100 is in the conductivity process, because of the Z font triggers the weak or skew of shell fragment 130 elasticity, all may cause and reflecting umbrella 120 loose contacts, cause contact impedance excessive, it is excessive to make flashlamp trigger the energy loss, even causes the problem that can't trigger.

Summary of the invention

Have in view of that, the invention discloses a kind of flash lamp module that triggers the power transfer energy consumption that reduces.

A kind of flash lamp module, it is by a reflecting umbrella, and one is inserted in the speedlight of reflecting umbrella and triggering shell fragment that one contacts with the reflecting umbrella outside surface is formed, and described triggering shell fragment and reflecting umbrella have a plurality of contact points.

Triggering on the shell fragment has a plurality of contact points to contact with reflecting umbrella, be used to increase the contact point number that triggers shell fragment and reflecting umbrella, thereby increase contact area and effectively reduce the contact impedance that triggers shell fragment and reflecting umbrella, reach and reduce the purpose that flashlamp triggers the loss of energy.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present invention is described in further detail.

See also Fig. 2 and Fig. 3, it is a kind of flash lamp module 200 that first embodiment of the invention provided, and it comprises a speedlight 210, reflecting umbrella 220, and one triggers shell fragment 230.Described reflecting umbrella 220 has a symmetrical plane 240 along flash lamp module 200 light directions and process speedlight 210 central shafts.

The inflation body is inserted in the reflecting umbrella 220 in the described speedlight 210, and two ends have the voltage difference about 300 volts, and when the gas in the speedlight 210 was triggered freeization, speedlight 210 got final product the moment conducting and produces flash of light.

The figure that the xsect of described reflecting umbrella 220 can be is parabola shaped, half elliptic, semicircle and other camber lines form, the xsect of reflecting umbrella 220 is parabola shaped in the present embodiment.Described reflecting umbrella 220 adopts conductive material to make, and preferably, described reflecting umbrella 220 adopts metal material to make.The two side 221,222 of reflecting umbrella 220 utilizes structural orientation that the outside surface of reflecting umbrella 220 is contacted with triggering shell fragment 230 about symmetrical plane 240 symmetries.

Described triggering shell fragment 230 is a M font symmetry shell fragment, contacts with two sidewalls 221,222 of reflecting umbrella 220 respectively by contact point 231,232, and its bottom is electrically connected with a circuit board.Described triggering shell fragment 230 conducts to reflecting umbrella 220 to high-tension electricity when flashlamp is opened.

When described flash lamp module 200 was worked, the high-voltage pulse that circuit board sends conducted to reflecting umbrella 220 via triggering shell fragment 230, makes the gas ionizationization in the speedlight 210 then, thereby 210 liang of terminal circuits of speedlight are temporarily connected, and realizes flash of light.

Be understandable that described triggering shell fragment 230 can require to make different shape according to reality, preferably, described triggering shell fragment 230 be a M font symmetry shell fragment, small and exquisite, attractive in appearance, material saving, is convenient to make and locate.Described triggering shell fragment 230 can contact with the optional position on reflecting umbrella 220 sidewalls 221,222 by contact point 231,232, and preferably, the line of described contact point 231,232 is convenient to balance left and right sides acting force perpendicular to symmetrical plane 240.Described contact point 231,232 also can carry out support limit to reflecting umbrella 220, prevents reflecting umbrella 220 slippages.

Reflecting umbrella 220 in the described flash lamp module 200 has two contact points with triggering shell fragment 230, can increase contact area by the increase of contact point number on the one hand, effectively reduces reflecting umbrella 220 and the contact impedance that triggers shell fragment 230.The structural orientation of 231,232 pairs of reflecting umbrellas 220 of two contact points on the other hand, effective inhibitory reflex umbrella 220 and trigger loose contact between the shell fragment 230, the contact impedance that reduces to bring because of loose contact increases.Trigger the loss of energy in transmission thereby reduce.

See also Fig. 4 Fig. 5, it is a kind of flash lamp module 300 that second embodiment of the invention provided, and it comprises a speedlight 310, reflecting umbrella 320, and one triggers shell fragment 330.Described reflecting umbrella 320 has a symmetrical plane 340 along flash lamp module 300 light directions and process speedlight 310 central shafts.

Described flash lamp module 300 is with the difference of flash lamp module 200: in the present embodiment, described triggering shell fragment 330 is the A-frame type, and is more stable.Contact with two sidewalls 321,322 of reflecting umbrella 330 by contact point 331,332 and 333, its bottom is electrically connected with a circuit board.Described triggering shell fragment 330 conducts to reflecting umbrella 320 to high-tension electricity when flashlamp is opened.

Be understandable that described triggering shell fragment 330 can require to make different shape according to reality.Described triggering shell fragment 330 can be a plurality of with the contact point of reflecting umbrella 320, the contact position of itself and reflecting umbrella 320 sidewalls 321,322 is also any, preferably, all have point of contact on the described

sidewall

321 and 322, so that to reflecting umbrella 320 location, preferably, described contact point can be formed a triangle at least on the vertical plane of same and symmetrical plane 340, can prevent effectively that reflecting umbrella 320 from slippages taking place, and trigger shell fragment 330 and be convenient to make, simple in structure.In the present embodiment, contact point 331,332 and 333 is distributed in respectively on two

sidewalls

321 and 322, and the triangle of its composition is vertical with symmetrical plane 340.

Reflecting umbrella 320 in the described flash lamp module 300 has three contact points with triggering shell fragment 330, can increase contact area by the increase of contact point number on the one hand, effectively reduces reflecting umbrella 310 and the contact impedance that triggers shell fragment 330.The structural orientation of 331,332 and 333 pairs of reflecting umbrellas 320 of three contact points on the other hand, effective inhibitory reflex umbrella 320 and trigger loose contact between the shell fragment 330, the contact impedance that reduces to bring because of loose contact increases.Trigger the loss of energy in transmission thereby reduce.

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.
