Abstract

An illumination device includes at least one semiconductor light emitting element, a supporting base, and a lamp housing. The semiconductor light emitting element is disposed on the supporting base. The lamp housing is disposed on the supporting base to cover the semiconductor light emitting element, and includes a first illuminating part and a lateral illuminating part surrounding the first illuminating part. A micro-structure is formed on a side of the first illuminating part and facing the semiconductor light emitting element for reflecting the light emitted from the semiconductor light emitting element.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device comprising a light-emitting semiconductor element and a microstructure and having a wide-angle light distribution. Background technique [0002] With the development of science and technology, light-emitting diodes (LEDs) have been widely used in people's lives. LED has the advantages of fast response, small size, low pollution, low power consumption, high reliability and long product life, so it can be used in lighting or display screens. General traditional lighting bulbs, such as incandescent bulbs, can be replaced by LED lighting devices. However, the light beam emitted by the LED is a directional light source, which is different from the traditional diffuse light source, and is subject to many limitations in application. Therefore, the conventional LED lighting device still cannot completely replace the traditional lighting bulb. [0003] Please refer to f...
