  • Publication number: 20240097080
    Abstract: A light emitting module includes a carrier, a light emitting element, a reflection layer, and a fluorescent layer. The light emitting element is disposed on the carrier. The reflection layer is disposed on the carrier and surrounds the light emitting element. The fluorescent layer covers at least part of the light emitting element. The disadvantages of over broad light emitting angle and low illuminance may be solved. Comparing with the related art, the present disclosure achieves an object of increasing the illuminance by at least 10%.

  • Patent number: 10631383
    Abstract: An illuminant module includes a first illuminant unit, a second illuminant unit, a first phosphor layer, and a second phosphor layer. The first illuminant unit includes one or more first LED dice and a current regulator electrically connected to the LED dice in series. The second illuminant unit includes one or more second LED dice. The first phosphor layer at least covers the first LED dice, wherein first phosphor layer and the first LED dice collectively provide an emission having a first color temperature. The second phosphor layer at least covers the second LED dice, wherein second phosphor layer and the second LED dice collectively provide an emission having a second color temperature, the current regulator is configured to adjust currents flowing to the first illuminant unit and the second illuminant unit for changing luminous flux of emissions emitted from the first illuminant unit and the second illuminant unit.
