Description

{DUAL MODE LIGHT DEVICE FOR BIKE}

An embodiment of the present invention relates to a bicycle light device to which a dual mode is applied.

With the recent development of the leisure industry and the sports industry, the number of people enjoying cycling as a hobby or as a club activity is increasing rapidly.

On the other hand, as the number of people enjoying bicycles increases, accidents related to bicycles such as incidents caused by failing to secure a full field of view at night and crashes caused by not installing rear warning lights frequently occur.

Conventionally, a field of view is secured at nighttime by using a generator for a bicycle, which is generated by friction with a bicycle wheel, and a headlamp electrically connected to the bicycle generator.

Such a headlamp uses a filament lamp bulb inside, so it can not emit light when stopped, and the brightness is not kept constant during driving. (If the pedal is slowly depressed, the brightness becomes blurred). In addition, the filament lamp bulb breaks frequently due to the fluctuation of the output of the bicycle generator, but it is troublesome to replace the bulb, so there are many people who ride the bicycle without light at all at night.

Recently, in order to prevent safety accidents, LEDs have been used as lights that have a longer life and produce brighter light.

Accordingly, studies have been made on a light device in which a bike user can freely change the on-off operation and brightness of the LED while the bicycle is traveling.

Here, the reflector 12 and the touch button 13 may be coupled to the body 11 by a thread (not shown) formed on the body 11. The body portion 11 may include at least one cooling hole (not shown) through which air flows on the outer circumferential surface, and a through hole (not shown) through which heat generated from the LED 103 may be emitted. The body portion 11 having such a structure may be formed to have a length of about 140 mm to 200 mm and the LED 103 may have a light amount of 1100 lumens by applying a T6 LED. In addition, the reflector 12 can diffuse the light evenly by diffusing the light emitted from the LED 103 through the rugged outer surface by applying the OP (orange peel) reflector 12.

The temperature-coloring layer is coated on the outer surface of the body part 11 by separating the temperature-coloring material into two or more sections according to the temperature change, And a protective film layer is coated on the temperature-coloring layer to prevent the temperature-coloring layer from being damaged. Here, the temperature-coloring layer may be formed by coating a temperature-coloring material having a color-changing temperature of not lower than 40 ° C and not lower than 60 ° C, respectively. The temperature discoloration layer is for sensing a change in temperature of the paint due to a change in color depending on the temperature of the outer surface of the body part 11. [ The temperature discoloring layer may be formed by coating a temperature discoloring substance whose color changes when the temperature becomes a predetermined temperature or more, onto the outer surface of the body portion 11. [ The temperature discoloring material is generally composed of a microcapsule structure having a size of 1 to 10 탆. The microcapsule can exhibit a coloring and a transparent color due to the coupling and separation of the electron donor and the electron acceptor depending on the temperature. In addition, the temperature-coloring material may have various coloring temperatures such as 40 ° C, 60 ° C, 70 ° C, 80 ° C, 90 ° C, 100 ° C, 120 ° C, 150 ° C, 180 ° C, These discoloration temperatures can be easily adjusted in several ways. Such a temperature-coloring material may be various kinds of temperature-coloring materials based on principles such as molecular rearrangement of an organic compound and spatial rearrangement of an atomic group. For this purpose, it is preferable that the temperature-coloring layer is formed so as to be separated into two or more sections according to the temperature change by coating two or more temperature-coloring materials having different color-changing temperatures. The temperature-coloring layer preferably uses a temperature-coloring material having a relatively low temperature of the discoloration temperature and a temperature-discoloring material having a relatively high discoloration temperature, more preferably a discoloration temperature of not lower than 40 ° C and not lower than 60 ° C A temperature-coloring layer can be formed using a temperature-coloring material. Accordingly, the temperature change of the outer surface of the body part 11 can be checked step by step. The protective film layer is coated on the temperature discoloration layer to prevent the temperature discoloration layer from being damaged due to an external impact, and it is easy to check whether the temperature discoloration layer is discolored or not, It is preferable to use a transparent coating material.
