The present invention relates to a vehicle signal lamp, and more particularly to a vehicle signal lamp using the LED.

In general, vehicles are equipped with signal lamps such as a reversing light, tail light, parking light, vehicle width light, direction indicator light, emergency flashing light, and braking light to inform the driver or pedestrian of another vehicle. .

Such a signal lamp is a filament-type bulb, and is mounted in a space enclosed by a case and a lens.

However, the filament-type signal lamp has the following problems.

That is, in the conventional filament type signal lamp, the filament is heated when the power is applied, and thus the temperature is radiated to emit light.

Therefore, it takes a predetermined time until the temperature radiation is made when the power is applied, there was a problem that the response is inferior.

In addition, when the response of the signal means due to the driver's operation during high-speed driving falls, the driver of the vehicle behind or the next lane does not respond quickly to the sudden situation of the preceding vehicle, causing serious obstacles to safe driving.

In addition, there is a problem in that the life of the signal lamp is lowered by maintaining the high temperature in the closed space by heat generated from the signal lamp, thereby increasing maintenance and repair costs due to frequent parts replacement.

The present invention has been devised to solve the above problems, the purpose of which is to implement a signal lamp using a very high response LED as well as a small amount of heat generated during lighting to help safe operation and prevent the occurrence of excessive heat It is to provide a vehicle signal lamp that not only improves the durability of the parts but also reduces maintenance and repair costs.

Another object of the present invention is to provide a signal lamp for a vehicle that can be used as it is mounted in a conventional socket as an LED as a light source.
