Problems solved by technology

However, during the electrical conduction process of the flashlight module 100, due to the elastic weakness or deviation of the zigzag trigger shrapnel 130, poor contact with the reflector 120 may be caused, resulting in excessive contact impedance and excessive loss of flashlight trigger energy transmission. Even cause problems that cannot be triggered

Embodiment Construction

[0011] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0012] see figure 2 and image 3 , which is a flashlight module 200 provided in the first embodiment of the present invention, which includes a flash tube 210 , a reflector 220 , and a trigger spring 230 . The reflector 220 has a symmetry plane 240 along the light emitting direction of the flash module 200 and passing through the central axis of the flash tube 210 .

[0013] The gas in the flash tube 210 is inserted into the reflector 220, and there is a voltage difference of about 300 volts at both ends. When the gas in the flash tube 210 is triggered to ionize, the flash tube 210 can be instantly turned on and Creates a flash.

[0014] The cross-section of the reflective umbrella 220 can be parabolic, semi-elliptical, semi-circular or other shapes formed by arcs. In this embodiment, the cross-section of the reflective umbrella 220 is ...

Abstract

The present invention relates to a flash lamp module, which is composed of the following components: a reflecting umbrella, a flashtube which is inserted in the reflecting umbrella, and a triggering shrapnel which is contacted with the external surface of reflecting umbrella, wherein a plurality of contact points exists between the triggering shrapnel and the reflecting umbrella. The triggering shrapnel are provided with the plurality of contact points contacting with the reflecting umbrella for increasing the number of contact point between the triggering shrapnel and the reflecting umbrella thereby increasing the contact area, effectively reducing the contact impedance between the triggering shrapnel and the reflecting umbrella and obtaining the purpose of reducing the transmission loss of flash lamp triggering energy.

Description

technical field [0001] The invention relates to a flashlight module, in particular to a flashlight module capable of reducing trigger energy transmission loss. Background technique [0002] At present, in the flashlight module, in order to reduce welding man-hours, save trigger connection wires, and miniaturize the module structure, it is often used figure 1 In the module 100 shown, the flash tube 110 and the reflective umbrella 120 are self-contained, and the structural positioning is used to make the reflective umbrella 120 contact with the Z-shaped trigger spring 130, the contact point is 131, and the lower end of the trigger spring 130 is electrically connected to a printed circuit board . The printed circuit board generates a high voltage of 3K~5K, which is transmitted to the reflector 120 by touching the Z-shaped trigger shrapnel 130, and then uses the energy of the instantaneous high voltage to excite the gas in the flash tube 110 to dissociate it, and the flash tube...
