An illustrative method of fabricating a lighting device comprises: encapsulating a light emitting chip with a silicone encapsulant; and sealing an assembly including at least the silicone encapsulant and the light emitting chip by disposing a light transmissive plastic layer as a unit over the assembly. | 12-04-2008 |
20130042510 | LED LIGHT MODULE FOR BACKLIGHTING - An LED light module and a backlit sign using at least one of the LED light modules are described. The LED light module comprises at least two LED light sources that are spaced apart from each other. Each of the LED light sources is covered by a lens and at least two of the lenses have a different shape than each other. The LED light module produces a uniform intensity of light on a backlit surface. The LED light module can include three LED light sources. Two of the lenses covering the LED light sources emit light that is distributed off-axis and a third of the lenses covering the LED light sources emits light that is distributed substantially on-axis. The backlit sign comprises a housing, at least one LED light module disposed in the housing and a backlit surface on the housing extending over the LED modules. | 02-21-2013 |
