a space 57 remains between the bottom of the array 20 and the horizontal section 54 that promotes dissipation of heat from the array 39 s leds 24 and electronic components 26 this helps the light 10 operate without overheating when the led array pcb 20 is installed there is approximately one inch between the leds 24 and the top 53 of the tube 50 the thickness of the tube 12 can vary with a suitable thickness being approximately 0 85 inches the tube 12 can be made from many materials with one of the preferred materials being acrylic the tube can be fabricated to illuminate at various colors and dissipate the emitting light to reduce bright and dark spots below the horizontal section 54 the tube 12 has two opposing tabs 55 56 are provided that run the longitudinal length of the tube lens to form a slot under the horizontal section 54 each tab 55 56 tapers toward the other and at the bottom of each tab there are opposing horizontal sections 58 59 with an opening between the edges of the two the slot formed by the member 54 and opposing tabs 55 56 houses the new mounting button 40 shown in fig4 a and 4 b when mounting the light 10 to a structural feature the buttons 40 are mounted along a line of the structural feature where the light s 40 are to be mounted a preferred mounting method is by a screw.
