The present invention relates to a safety helmet, and more particularly to a multifunctional safety helmet using sunlight.

Users of motorcycles and bicycles, such as motorcycles and inline skates are increasing year by year, and accordingly, traffic accidents of passengers such as motorcycles or inline skates are rapidly increasing. In addition, about 80% of the main causes of death or serious injury from motorcycle or bicycle accidents are due to non-wearing helmets.

Meanwhile, a conventional safety helmet for a motorcycle or an inline skate safety helmet merely has a function of protecting a wearer's head in the event of an accident, and thus there is no means to alert the driver of an automobile approaching from the outside. It was very vulnerable to collision with Sudan and collision.

In particular, during the night driving of motorcycles and bicycles, motorists approaching from behind are not aware of the existence of motorcycles or bicycles. Therefore, it is very likely to cause large accidents such as collision, collision, death of a passenger, and serious injury. In fact, more than half of motorcycle or bicycle accidents occur at night when driving at night.

Accordingly, when driving a motorcycle or a bicycle during the day and at night, a motor vehicle approaching from behind can easily recognize the presence of the motorcycle or the bicycle, so that a sufficient safety distance can be secured in order to prevent a traffic accident due to a collision or a collision. Means are needed.

The problem to be solved by the present invention, when driving a two-wheeled vehicle or riding inline skates can be prevented from accidents by emitting light so that the driver can be identified at a long distance, depending on the situation by charging with sunlight or using an external power source When it is not possible to charge the helmet, and usually do not use a helmet to provide a multi-functional safety helmet that can be used as a power source for charging a digital device or indoor lighting.

The external power supply unit, a direct current (AC) power input unit for receiving a direct current (AC) power from the outside; And an AC / DC converter converting direct current (AC) power inputted to the direct current (AC) power input unit into alternating current (DC) power and supplying it to the storage battery.

The external device charging unit may be provided as a pin port or a USB port.

An on / off switch for turning on / off the light emitting diode; The display apparatus may further include a mode selection unit configured to select a light emitting mode in which the light emitting diode continuously emits light, and a flashing mode in which the light emitting diode blinks.

The light emitting unit may be provided integrally with the helmet body, and two light emitting units may be provided from a rear surface of the helmet body to an upper surface thereof.

According to the present invention, when driving a two-wheeled vehicle, such as a bicycle or motorcycle or when riding in-line skates to emit light to be able to identify the driver at a long distance there is an excellent effect that can effectively prevent safety accidents.

In addition, it can be used permanently by utilizing solar light, which can not only improve economic efficiency, but also be environmentally friendly, and can be charged using external power when solar light is not available due to poor weather conditions. Regardless of the fact, it also has the advantage of being available in all weather.

Furthermore, when not wearing a helmet, it can be used for charging portable digital devices (mobile phones, MP3 players, digital cameras, etc.) using electric energy stored in the helmet, or can be used for multi-function such as indoor lighting or portable lantern replacement.
