Abstract: The present invention provides a luminance control method and a luminance control device for use with a projection system having a light source and a color wheel. The luminance control device includes a processing module, a power supply unit and a lamp driver. The luminance control method includes steps of issuing a power control signal to define a plurality of time segments in a cycle period, wherein luminance messages composed of different numbers of pulses are included in respective time segments; reading out the luminance messages included in the respective time segments in receipt of the power control signal; and adjusting luminance values of the light emitted by the light source to be projected to the color wheel according to the luminance messages.

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.
