A switch is provided at the center of the upper lid, and when the switch is pressed, the light emitter and the power supply unit are connected to generate light. The inconvenience of using the key in a dark place is solved by correctly recognizing the direction of the key and the position of the keyhole with the light of the light. Also, when going up and down the stairs, light will illuminate your dark feet to ensure safety.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a key technology, and more particularly, to a technology in which a light is provided in a head portion of a key and can be illuminated by a light when using the key or when going up and down dark stairs.

[0002]

[Prior art]

 Lighting is essential for people to see clearly at night, and keys are essential for unlocking. However, when using the key in a dark place, there was a problem that the keyhole could not be seen due to insufficient light rays. The place where the key is used is generally a relatively dark place such as stairs and warehouses, so it was very inconvenient to use the key. In addition, since the surrounding area is difficult to see on dark stairs, accidents such as falling when climbing the stairs were easy to occur. And these were all due to lack of light in dark places.

[0002]

[Problems to be solved by the invention]

 The main purpose of the present invention is to solve the inconvenience due to lack of light when using a key. Another object of the present invention is to prevent accidents that occur when going up and down dark stairs.

[0004]

[Means for solving the invention]

 The present invention comprises a key head unit, a power supply unit provided inside the key head unit, a light emitter, and an upper lid. A switch is provided at the center of the upper lid, and when the switch is pressed, the light emitter is connected to the power supply to generate light. The inconvenience of using the key in a dark place is solved by correctly recognizing the direction of the key and the position of the keyhole with the light of the light. Also, when going up and down the stairs, illuminate your dark feet with lights to ensure safety.

[Embodiment of the invention]

 As shown in FIGS. 1 and 2, the key head unit 1 includes a power supply unit 2, a light emitting body 3, and an upper lid 12 provided inside the key head unit 1, and a concave portion 111 is formed in a central portion of the key head unit 1. And a set of a battery chamber 113 and a battery chamber 113 'are formed in the center of the recess 111. The power supply unit 2 is inserted into the battery compartment 113 and the battery compartment 113 ', and a groove 114 is provided between the battery compartment 113 and the battery compartment 113'. Around the battery chamber 113 and the battery chamber 113 ′, two positioning grooves 112, 112 ′ having a step are provided, and the positioning grooves 112, 112 ′ are waterproofed in combination with waterproof walls 123, 123 ′ on the back side of the upper lid 12. Have an effect. A non-slip 122 is formed at the front end of the upper lid 12 surface so that the upper lid 12 can be easily removed. Further, a switch 121 is provided at the center of the upper lid 12, and a mounting portion 116 is provided at one end of the key head 1 described above. The light-emitting body 3 is installed in the mounting portion 116, two holes 115 are provided behind the mounting portion 116, and the holes 115 are connected to the power supply unit 2 through the conductor 31 of the light-emitting body 3.

As shown in FIG. 3, when the switch 121 is not pressed, the conductor 31 of the luminous body 3 and the power supply unit 2 are not connected, and when the switch 121 is pressed, the conductor 31 of the luminous body 3 becomes The light is immediately connected to the power supply unit 2 to generate light. As shown in FIG. 5 and FIG. 6, when the light emitter 3 is installed on one side of the key head part 1, the light emitted by the light emitter 3 when used is concentrated on the tip of the key, so that it can accurately reach the target. Light hits. Also, when the light emitter 3 is installed at the center of the key head unit 1, light shines on the target exactly as in the case where it is installed on the side surface. As shown in FIG. 7, when using only one power supply unit 2, the battery chamber 113 is provided at an appropriate position in the center of the recess 111, and a groove 114 is provided on the side of the light emitting body 3. The groove 114 and the hole 115 correspond to each other, and the conducting wire 31 of the light emitting body 3 is connected to the power supply unit 2 through the groove 114 and the hole 115.

[0004]

[Effect of the invention]

 The light in the key head solves the shortage of light when using the key in a dark place. Also, when going up and down the stairs, the lights on the key head illuminate dark feet to enhance safety.
