The present invention relates to an LED bulb for replacing a halogen bulb for automobiles, and more particularly, to replace a high-power inefficient halogen bulb with a low-power high-efficiency LED bulb, but to reflect the light emitted from the LED bulb to extend the light to the outside The present invention relates to an LED bulb for replacing a halogen halogen bulb for a vehicle that can maintain a constant range of light to be irradiated.

이륜차를 포함하는 자동차는 외부환경 및 시간에 따라 전방으로 빛을 조사하여 운전자의 시야를 확보하고 타차량에게 차량의 진행 경로를 알려주기 위한 목적을 갖는 조명(램프)이 구비된다.
A vehicle including a two-wheeled vehicle is provided with lights (lamps) for the purpose of securing a driver's field of vision by injecting light forward according to the external environment and time and informing other vehicles of the vehicle's traveling path.

이러한 조명은 사용하는 목적에 따라서 구분되는데, 전방을 비추기 위한 목적을 갖는 헤드램프와 차량의 진행 경로를 알려주기 위한 목적을 갖는 방향지시등, 안개, 우천시 헤드램프와 더불어 운전자의 시야 확보 및 차량의 위치를 알려주기 위한 안개등과 차량의 후진시 점등되는 후진등 등이 있다.
These lights are classified according to the purpose of use, together with a headlamp for the purpose of illuminating the front and a headlight for the purpose of indicating the path of the vehicle, the headlights in case of fog and rainy weather to secure the driver's sight and position the vehicle. There are fog lights to inform you of the lights and reversing lights that are turned on when the vehicle reverses.

종래의 조명에서 사용되는 광원으로는 보통 할로겐(Halogen)전구가 사용되고 있는데, 할로겐전구는 220V 를 12V로 변환하여 사용하는 것으로 가격이 저렴하여 다양하게 사용되고 있으나, 사용 중 발생하는 열이 많고 사용하는 전기량에 비하여 저휘도(輝度)를 갖고 수명이 짧기 때문에 교체주기가 짧은 문제점이 있었다.
Halogen bulbs are commonly used as a light source used in conventional lighting. Halogen bulbs are used by converting 220V to 12V and are inexpensive. However, they are used in various ways due to their low price. Compared with the low brightness and short lifespan, the replacement cycle was short.
