Embodiment Construction
[0019] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.
[0020] Examples, see figure 1 Shown: remote phosphor, including transparent resin layer 1 and phosphor layer 2. Wherein, the phosphor layer 2 is disposed on one side surface of the transparent resin layer 1 . The phosphor layer 2 can adopt various common phosphor layers. Optimally, the phosphor layer 2 is a mixture of phosphor, binder and coupling agent. Of course, the adhesive can be a common water-resistant or water-soluble adhesive, and the coupling agent can be a common material such as a silane coupling agent. Further, the weight ratio of the phosphor powder, binder and coupling agent in the phosphor powder layer 2 is 100:(0.01-1):(0.01-1). Optimally, the weight ratio of phosphor powder, binder and coupling agent in the phosphor powder layer 2 is 100:0.05:0.05.
