Abstract
An illumination device includes a base, a light-emitting module, a first layer, and a second layer. The light-emitting module is disposed on the base for generating a progressive-type light-emitting intensity. The first layer encapsulates the light-emitting module. The second layer encloses the first layer. The second layer has a progressive-type thickness corresponding to the progressive-type light-emitting intensity, and both the progressive-type light-emitting intensity and the progressive-type thickness are decreased or increased gradually, thus the progressive-type light-emitting intensity can be transformed into the same light-emitting intensity through the progressive-type thickness of the second layer.
Claims6
An illumination device, comprising:
- a base;
- a light-emitting module disposed on the base and electrically connected to the base for generating a progressive-type light-emitting intensity;
- a first layer encapsulating the light-emitting module;
- and
- a second layer enclosing the first layer and having a phosphor powder with a plurality of phosphor particles, wherein the second layer has a progressive-type particle radius of the phosphor powder corresponding to the progressive-type light-emitting intensity, the progressive-type light-emitting intensity varies inversely as the progressive-type particle radius of the phosphor powder, and the progressive-type light-emitting intensity is transformed into the same light-emitting intensity through the progressive-type particle radius of the phosphor powder in the second layer.
