  • Publication number: 20140091329
    Abstract: The present disclosure involves a lighting instrument. The lighting instrument includes a board or substrate, for example, a printed circuit board substrate. The lighting instrument includes a plurality of light-emitting diode (LED) dies disposed on the substrate. The LED dies are spaced apart from one another. Each LED die is covered with a respective individual phosphor coating that is coated around the LED die conformally. Due at least in part to the individual phosphor coatings, the LED dies and the lighting instrument may assume a substantially white appearance in an off state. The lighting instrument also includes an encapsulation structure disposed over the substrate. The encapsulation structure may be a diffuser cap that encapsulates the light-emitting dies within. A diffuser gel fills the space between the encapsulation structure and the LED dies.
