Abstract

The invention relates to a light-emitting diode (LED) car lamp device which comprises a shell, a light-transmitting lampshade and an LED module. The shell and the light-transmitting lampshade are combined to define an internal space, the LED module is arranged in the internal space, and the shell comprises an inner layer and an outer layer which is combined with and encircled around the inner layer, wherein the outer layer has a heat conductivity coefficient lower than that of the inner layer for preventing temperature outside the shell from being conducted into the shell, and thereby increasing the temperature in the shell or influencing the operation of the LED module.

Description

technical field [0001] The invention relates to a vehicle light device, in particular to a light emitting diode vehicle light device. Background technique [0002] refer to figure 1 , is a conventional light-emitting diode lamp device 1 of Japan Koito Company, which includes a housing 11, a light-transmitting lampshade 12 combined with the housing 11, a base 13 arranged in the housing 11, and a plurality of bases arranged on the base The light emitting diode 14 of the base 13 , and the base 13 is formed with a plurality of cooling fins 131 . [0003] The position where the light-transmitting lampshade 12 is located is in front of the entire vehicle light device 1. When the vehicle light device 1 is installed on the vehicle body 100, the heat energy generated inside the vehicle light device 1 (for example, from the light emitting diode 14) is generated by the The cold air blown to the light-transmitting lampshade 12 (shown by the imaginary line arrow in the figure) exchange...
