Abstract: The present invention relates to a simple and reliable portable flashlight shaped instrument that combines in a first embodiment an array of a combination of ultraviolet, white and multicolor LED arrays in combination with a broad band hydrocarbon gas detector and, in a second embodiment, a combination of ultraviolet, white and infrared LED arrays. There is also a readily attachable collector cone with a plurality of magnifying lenses, which are removable and a kit assembly with an extender sleeve for the collector cone, and a collector cone heater chamber. Many types of hydrocarbons fluoresce under the influence of an ultraviolet light. This rugged constructed instrument will find trace amounts of suspect materials and is extremely easy to use. The built in gas detector is cable of detecting trace amounts of accelerants days after a fire.

Abstract: The present invention relates to a switch plate assembly having a night light-type illumination device or a switch plate with a light source formed of a plurality of colored (red, blue, and green) LEDs. In one embodiment, the LEDs are covered by a pair of translucent, arcuate diffusers in series. The diffusers aid in uniformly or evenly dispersing the generated colored light from the cover plate or night light housing. The desired colors are generated in varying intensity for each LED. Each embodiment includes color generation control for performing a response based on a sensed condition such as a fire alarm, a doorbell, or burglar alarm. The light system can also be wired to an alarm signal generation system.
