Description

Portable lighting equipment

The present invention relates to a portable lighting device, and more particularly, using a solar cell can be used as a vehicle safety tripod or a portable flashlight when the vehicle breaks down, and at the same time the lighting device is securely housed inside the upper part of the main body to The present invention relates to a portable lighting device capable of preventing damage by a shock.

Conventional portable lighting devices are known as portable flashlights, portable stands, etc. The portable flashlights and portable stands use a disposable battery such as a primary battery or a storage battery such as a rechargeable secondary battery.

When the conventional portable lighting device (eg, portable flashlight, portable stand, etc.) as described above uses a primary battery, a new primary battery must be purchased and used every time the primary battery is completely consumed. There is a cost burden and the inconvenience of having to replace the battery.

In addition, when the conventional portable lighting device (eg, portable flashlight, portable stand, etc.) uses a storage battery such as a secondary battery, it is charged with commercial AC power at home every time the battery is completely depleted. Since it is necessary to try, from the user's point of view, there is an inconvenience in that it is restricted in the charging time and the charging place.

In recent years, portable lighting devices using solar cells have been developed, but they are difficult to carry due to their large size and volume, and in particular, the overall structure of the product is complicated and the assembly process takes a lot of manpower and time. There is a problem that the cost increases.

Lighting device using solar cell is divided into a device that can adjust the angle of the lighting device and a device that can adjust the angle. When the angle of the lighting device is fixed, the user has to move the lighting device in the desired direction all the time. In the case of the device that adjusts the angle of the lighting device, most of the lighting device is separated from the main body, and after separating and fixing by lifting and lowering, it is necessary to adjust the angle of the lighting device again and rotate it by 360 °. In the case of the lighting device is easily exposed to the outside there is a problem that is easily broken by an external impact.

In addition, when the conventional lighting device is broken by an external impact, it is difficult to replace the parts, there is a problem that a new product must be purchased.

The present invention has been made in view of the above-described conventional problems, and its object is to easily turn on the lighting device using a solar cell and use it as a portable flashlight, while simultaneously accommodating the lighting device inside the upper part of the main body safely to prevent external impacts. It is to provide a portable lighting device that can be prevented from being damaged in advance, and the lighting device formed on the upper portion of the main body can be rotated forward 135 ° so that the vehicle can be used as a safety tripod for the vehicle in case of failure of the vehicle.

Another object of the present invention is to charge and discharge the battery built in the main body using a solar cell, the state of charging and discharging the battery, and supplying the charged power of the battery to the drive power of an external electric device (mobile phone, MP3, etc.) And, when the battery is discharged and the solar light is not available, the user can easily recognize the status of receiving the charging power of the external electric device through a plurality of indicators, and the user can easily recognize the external electric device (mobile phone) using the USB port. It is to provide a portable lighting device that can supply the driving power simply by switching the USB switch to the ON state when supplying the driving power to the MP3).

Another object of the present invention is a handle formed on one side of the main body can be inserted and withdrawn in a sliding manner to the inside of the main body to simplify carrying and moving while minimizing the overall size and weight, in particular the lighting device accommodated inside the main body It is to provide a portable lighting device to form an angle adjusting portion at the end of the rotating shaft of the user to facilitate the user's convenience by easily rotating the lighting device at a desired angle.

Another object of the present invention is to install a high-brightness LED to the lighting device to improve the linearity of the lighting device, when the solar light is not charged by using an adapter (DC 9V) and a battery cigar jack (12V) for easy storage battery It provides a portable lighting device that can be charged and used anywhere.

In order to achieve the object of the present invention, the rear case is coupled to the rear of the front case is provided with a solar cell and a plurality of indicator lights in the front lower portion, a seating portion is formed in the upper inside of the front / rear case, the rotating shaft on both sides of the seating portion A body having a hole and a handle formed on one side of the front / rear case; A battery for charging electricity produced by the solar cell is installed inside the rear case, and detects a charge / discharge state of the battery in a state in which the solar cell and the battery are electrically connected to control lighting of a plurality of indicators. A main board accommodated in the main body, a power switch is installed on one side of the main body on which the handle is formed, and a control unit on which the USB switch, a USB port, and a power charging terminal are formed; And an upper case and a lower case are installed at a seating portion of the front / rear case, and rotation shafts formed at both sides of the upper case are inserted into the rotation shaft holes to be rotatably fixed at a predetermined angle, and at least one LED is installed on the upper surface.
