Abstract: This invention relates to a luminous decoration strip which essentially comprises a main housing having a light emitting module disposed therein. The light emitting module includes a LED luminant, a control circuit and a power supply unit. A light guide sheet having reflecting stripes provided thereon is attached to the main housing such that the light emitted from the LED luminant is directed onto the reflecting stripes. The reflecting stripes reflect the light on both surfaces of the light guide sheet in such a manner that diversified luminous patters can be produced. In this way, the luminous decoration strip can be used in various fields, such as hand decoration, head ornaments, or diversified character patterns for advertising purpose etc.

Abstract: An LED light source device with color temperature adjustment capability includes at least one light-emitting diode and a color temperature conversion element. A front end of the light-emitting diode has a light-emitting end. The color temperature conversion element is disposed in front of the light-emitting end of the light-emitting diode. The color temperature conversion element includes a light-transmitting substrate and color temperature conversion materials. The color temperature conversion materials are provided on/in the light-transmitting substrate. The color temperature conversion materials include high refractive index materials and low refractive index materials. The high refractive index materials that are selected from the group consisting of TiO2, Ti3O5 or Ta2O5. The low refractive index materials that are selected from the group consisting of SiO2 or MgF2. The light beam emitted by the light-emitting diode passes through the color temperature conversion element to change its color temperature.
