Of the present utility modelly provide a kind of flashlight on the other hand, having comprised: the stack shell of double as conductor, it has the inner chamber that holds battery and an end and connects for lamp holder and establish, and the other end and tail-hood are spirally connected; And lamp holder, described lamp holder has the tungsten filament lighting bulb, wherein also comprises the flashlight tail-hood with aforementioned structure.

Because flashlight tail-hood and the flashlight thereof with signal lamp and switch of the present utility model has above structure, the LED bulb is arranged in tail-hood, thereby reduced the volume of lamp holder effectively, can not make the complex structure of flashlight because of the illumination functions that has increased flashlight, and the construction of switch of control LED is simple, includes only first, second contact.In addition, the transparent colloid that is provided with in tail-hood both can waterproof, and the light that LED is sent is more even, soft again.Further, translucent cover mould in the time of can also reducing encapsulating is set, greatly reduce manufacturing cost, being provided with of refractive body helps form various reflecting effects.

Should be appreciated that above generality is described and the following detailed description is all enumerated and illustrative, purpose is in order to provide further instruction to claimed the utility model.

Other features and advantages of the utility model provide in explanation subsequently, partly can be apparent from the description, and maybe can find out from enforcement of the present utility model.The purpose of this utility model and other advantage can be understood, obtain from the structure that following written explanation, claim and accompanying drawing provide especially.

Description of drawings

The accompanying drawing of forming the part of this specification helps further to understand the utility model, and these accompanying drawings illustrate embodiment more of the present utility model, and can be used for illustrating principle of the present utility model with specification.In the accompanying drawing:

Fig. 1 shows the flashlight with tail-hood, is provided with signal lamp and switch in this tail-hood;

Fig. 2 is for having the cutaway view of the flashlight tail-hood of signal lamp and switch among Fig. 1; And

Fig. 3 shows the electrical connection of contact switches and osram lamp and light emitting diode.

The specific embodiment

Referring now to accompanying drawing to being described in detail as follows according to preferred embodiment of the present utility model.

With reference to Fig. 1, flashlight 1 comprises the lamp adapter assembly 10 with osram lamp 11, the stack shell 20 of double as conductor, and tail-hood 30.Lamp adapter assembly 10 and tail-hood 30 are screwed onto the two ends of stack shell 20 respectively.

Lamp adapter assembly 10 comprises lampshade 14, is located at the transmissive mirror 12 and the luminescence unit of lampshade front side, and this luminescence unit comprises osram lamp 11, reflector 13 and lamp socket 17.One utmost point pin of osram lamp 11 is electrically connected by the positive pole of lamp socket 17 and spring 16 and battery 60, and another utmost point pin of osram lamp is electrically connected with stack shell by lamp socket 17 and spring 15.Therefore, also need tail-hood 30 that the negative pole and the stack shell 20 of battery are electrically connected, could constitute the loop and light osram lamp.Introduce tail-hood 30 below in detail.

As shown in Figure 2, the inboard of tail-hood housing 31 has positioning seat 39, circuit board 40 is positioned on the positioning seat 39, and it is fixing by trim ring 33, one side of circuit board 40 relative batteries has electric contact terminal 38, and here electric contact terminal is a spring, on circuit board, the both sides of spring are equipped with two contacts respectively, promptly short contact 37, long contact 36, two contacts are L shaped, and extend to the inwall of tail-hood housing 31 respectively its end, thereby when tail-hood is screwed into stack shell, the stack shell end face can electrically contact short contact and long contact,, long contact contact stack shell end face earlier is set here, short then contact contacts the stack shell end face again, for example long contact is than the high 0.5mm of short contact, and is perhaps high more.

The another side of circuit board 40 is provided with a plurality of light emitting diodes 32 (LED), these light emitting diodes can have multiple color and multiple color combinations and use as signal lamp, can be cascaded between a plurality of light emitting diodes, also can be in parallel, perhaps series-parallel connection.Circuit board is provided with corresponding circuit, makes long contact 36, light emitting diode 32, electric contact terminal 38 be electrically connected, and promptly when long contact touched stack shell end face (positive pole), electric current returned GND by light emitting diode.Short contact 37 is direct and electric contact terminal 38 electrical connections by the circuit that is provided with on the circuit board, and when promptly short contact touched stack shell end face (positive pole), electric current was directly got back to GND, without light emitting diode.

Also be connected with the translucent cover 35 of transmission light emitting diode light at an end of tail-hood housing 31, translucent cover 35 is connected to the end of tail-hood housing and forms internal cavities, has filled transparent colloid 42 in this internal cavities, thereby has the function of waterproof.Also can be provided with refractive body 34 in internal cavities, the light that LED is sent reflects towards periphery, and preferred refractive body is horn-like, and an end is plugged on the circuit board, and the equal portion of a plurality of light emitting diodes is around refractive body.

In addition, on circuit board, can also be provided with the chip of a plurality of LED flash of control, this chip can be a disclosed type among the Chinese utility model patent CN2533376Y.Also be provided with O-ring seal at each threaded engagement place, the O-ring seal between transmission lens and the lampshade 51 for example, the O-ring seal 52 between lampshade and the stack shell, the O-ring seal 53 between stack shell and the tail-hood.Being provided with of O-ring seal helps prevent entering of steam and foul.

In conjunction with reference to Fig. 3, screw the switch tail-hood, when long contact does not all contact the stack shell end face with short contact, circuit breaker, osram lamp and LED bulb all do not work; When long contact touched the stack shell end face, electric current returned the negative pole of battery by a plurality of LED, because the LED bulb is assigned to most of voltage, the voltage of osram lamp is very low, and electric current is very little, is not enough to light osram lamp, so at this moment be that the LED bulb is bright and osram lamp does not work; When short contact touched the stack shell end face, the LED bulb was by short circuit, and electric current is directly got back to GND without the LED bulb, and osram lamp obtains all voltages of battery, so at this moment osram lamp is lighted, and the LED bulb does not work.

In the utility model, can use various lamp holders, as long as stack shell is that conductor can be realized the purpose of this utility model with osram lamp.

The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
