Abstract: An exemplary embodiment of the present disclosure provides a solid-state light emitting device. The solid-state light emitting device includes a stair-type bowl, a plurality of light emitting chips, and an encapsulation glue. The stair-type bowl includes a base and a ring stair structure. The ring stair structure includes a plurality of ring tread surfaces and a plurality of ring riser surfaces connected to the ring tread surfaces. The ring stair structure is connected to the base. The base has a bottom surface. The ring stair structure surrounds the bottom surface and protrudes from the bottom surface. The light emitting chips are respectively disposed above the ring tread surfaces and the bottom surfaces. The stair-type bowl is filled with the encapsulation glue. The encapsulation glue covers the light-emitting chips.

Abstract: A plant illumination apparatus includes a light source module including a first light source and a second light source generating lights having different wavelengths, an environment-detecting module detecting an external environment to obtain a real-time environment parameter, and a control module connected to the light source module and the environment-detecting module. The control module includes a processor unit and a storage unit storing a database of plant growing environment parameters. The processor unit loads at least one preset growing environment parameter corresponding to a plant growth timing from the database of plant growing environment parameters, and compares the preset growing environment parameter with the real-time environment parameter to output at least one comparison result. The processor unit adjusts the first light source and the second light source according to the comparison result, so that an adjusted environment parameter matches the preset growing environment parameter.
