Detailed Description

The present invention will be described in further detail below with reference to the accompanying drawings by way of specific embodiments. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1-2, a multipurpose night vision compatible finger reading lamp is shown. The finger reading lamp comprises a lamp shell 6, a rubber outer sleeve 1 and a rear end cover body 7. The rubber casing 1 surrounds the periphery of the front part of the lamp shell 6. The rubber outer sleeve 1 is tightly sleeved and matched with the front part of the lamp shell 6. The rear end cover 7 surrounds the periphery of the rear portion of the lamp housing 6. The rear end cover body 7 is in threaded connection and matching with the rear part of the lamp shell 6. The inside of the lamp housing 6 defines a housing accommodating space. The housing accommodating space is sequentially provided with an LED light source part, a printed board part 5 and a battery shell 8 from front to back.

The LED light source component is provided with a filter film 2, a reflecting cover 3 and a contact pin type LED 4. The light-emitting direction of the pin type LED4 is forward. The filter 2 is located at the front end of the contact pin type LED 4. The reflector 3 surrounds the outer periphery of the pin LED 4. By means of the structure, the light performance requirement of night vision compatibility of the lamp is guaranteed.

The printed board part 5 is clamped in the mounting groove of the lamp shell 6. The printed board part 5 is electrically connected to the pin LED 4. The button switches on the front and back surfaces of the printed board part 5 are embedded into the bayonet of the lamp shell 6. The protruding parts on the two sides of the rubber outer sleeve 1 correspond to the positions of the two-side button switches of the printed board part 5, and the switching of gears can be realized by pressing the switch on any side of the finger lamp. The singlechip on the printed board part 5 receives the trigger signal, outputs PWM with different duty ratios, and drives the on-off of the MOS tube, thereby realizing the switching of the bright state, the dark state and the off state of the contact pin type LED 4. Meanwhile, when the chip has a timing function and is not operated for a long time, the output is low, the MOS tube is turned off, and the contact pin type LED4 is automatically turned off.

The battery shell 8 is clamped in the mounting groove of the lamp shell 6. The inside of the battery shell 8 contains a button battery 9. A front end spring is arranged between the button cell 9 and the printed board part 5, and the button cell 9 and the printed board part 5 are electrically connected through the front end spring. A rear end spring is arranged between the button cell 9 and the rear end cover body 7. The front end spring and the rear end spring are designed to ensure that the axial displacement of the internal structure is limited and the stability of the structure is ensured.

The above description is only intended to represent embodiments of the present invention, which are more specific and detailed, but not to be construed as limiting the scope of the claims. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
