The present invention relates to a helmet and a method for dealing with an accident using the helmet, which the helmet includes: a helmet body part made of a resin having a semi-spherical space for receiving the head of a wearer; a light part arranged in the front of the helmet body part having LEDs mounted on a substrate to provide the wearer with lighting; a metallic heat radiator extending from the front of the helmet body part to the back thereof along the upper central line of the helmet body part and partially contacting the back of the substrate to discharge heat; a communication device part received in the helmet body part for dealing with communication and emergency circumstances; and a battery received in the helmet body part for supplying power to the communication part and light part. According to the present invention, the metallic heat radiator is integrated with the resinous helmet body part by injection molding of different materials, so that the heat generated from the LEDs of the light part is discharged upwards from the top of the helmet, thus preventing the wearer from being subjected to the discomfort caused by the heat generated from the LEDs.

A linear multi-color LED illumination device that produces uniform color throughout the output light beam without the use of excessively large optics or optical losses is disclosed herein. Embodiments for improving color mixing in the linear illumination device include, but are not limited to, a shallow dome encapsulating a plurality of emission LEDs within an emitter module, a unique arrangement of a plurality of such emitter modules in a linear light form factor, and special reflectors designed to improve color mixing between the plurality of emitter modules. In addition to improved color mixing, the illumination device includes a light detector and optical feedback for maintaining precise and uniform color over time and/or with changes in temperature. The light detector is encapsulated within the shallow dome along with the emission LEDs and is positioned to capture the greatest amount of light reflected by the dome from the LED having the shortest emission wavelength.

An illuminating device includes: first lenses individually corresponding to LEDs; a light control member including light transmission channels individually corresponding to the first lenses and a light blocker surrounding the light transmission channels; and second lenses individually corresponding to the light transmission channels. Each first lens includes a light concentrator for producing concentrated light by concentrating light emitted from a corresponding LED, and a reflector surrounding the light concentrator to produce reflected light by reflecting light emitted from the corresponding LED in a direction across the concentrated light. Each first lens outputs illumination light including the concentrated light and the reflected light produced from the corresponding light emitting diode. Each light transmission channel transmits the illumination light output from a corresponding first lens. The light blocker prevents transmission of the illumination light emitted from each first lens. Each second lens refracts the illumination light transmitted by a corresponding light transmission channel.
