Description

Flashlight {flash light}

The present invention relates to a flashlight, and more particularly, to a flashlight, which can be carried using an LED (Light Emitting Diode) that can lead a light source of high luminance with less power than a conventional general bulb, And a flashlight which enables both functions of a warning light to be used.

Generally, it is well known that a lantern is necessarily used at night or in a dark place when outdoor activities such as a home, camping, fishing, mountain climbing, and trekking are performed. And the battery is supplied with power from the built-in battery so as to be turned on.

In addition, although the above-described various types of lanterns generally employ a bulb as a light source, LEDs are mainly used as a light source for the purpose of prolonging the service life and increasing the amount of light entering the near-end.

Such LED lanterns are mainly used for brightening the interior of the tent, for identifying needles and fish species when fishing, and for brightening the surroundings, and are often used in nighttime and dark environments even when outdoor activities such as mountain climbing or trekking are performed.

In addition, even when a sufficient amount of light is not secured only by the internal illumination in the underground space or the dark interior, or when there is no internal lighting means, the lanterns of various shapes and structures are used to brighten the surroundings and the work space, .

However, the above-mentioned LED lantern can not perform other special functions except for illuminating the surroundings. For example, the function of a light guide rod or a signal rod could not be combined.

In other words, when a police officer controls or clears traffic at nighttime or in a rainy weather where visibility is difficult to obtain, or when driving accident, construction site safety, parking guide, caution when a vehicle breaks down, Usage is a well-known fact.

These signal lamps are turned on to generate light for securing a field of view to the nighttime, thereby enabling an optical signal for performing the above-mentioned tasks.

However, a conventional light guide rod or a signal rod performs only the function of the light guide rod, and the function as a lantern can not be used in combination. For this reason, there is a disadvantage that the lantern and the light guide rod must be provided, respectively, and there is a problem in that it is also burdensome in terms of cost.

In order to solve such a problem, 'LED lamp' is disclosed in Korea Utility Model Registration No. 20-0479562 and Utility Model Registration No. 20-0479563.

Such an 'LED light fixture' has a lantern function or a flash function, and an external cover can be installed to use the warning light function.

However, such an 'LED light fixture' may be inconvenient to use a lantern function or a flash function because a part of light may be emitted to a place other than a lantern function or a flash function when a lantern function or a flash function is used, And damage to light diffusion may occur.
