Abstract:
The present invention relates to a system for providing motion-screen based on body perception which is comprising of a sensor for sensing whether the user is taking a seat; a controlling section for calculating motion time by means of taking a seat of the user when the user takes a seat, and for abstracting multimedia data in response to the motion time; and an outputting apparatus for outputting the abstracted multimedia data. When the user performs a computer work or a business work, the present invention has an effect for protecting a mental and physical disorder of the user, an occupational disease, a stress, an amblyopia, and the like, by means of providing a motion-screen each predetermined time by calculating the motion time of the user.
Abstract:
An exchangeable shade light emitting diode (LED) bulb including a metal LED board having at least one LED and thermal conductivity, a transparent or translucent shade for collecting or diffusing light emitted from the LED, a metal structure having the same shape as the metal LED board, and including a coupling recess for close coupling with the metal LED board, and a primary fastening step fastened to the shade in order to couple with or decouple from the shade, and the metal structure forming an outer circumference of the exchangeable shade LED bulb, a body coupled with the metal structure and forming the outer circumference of the exchangeable shade LED bulb, and a control board connected with the metal LED board through a wire in order to drive the LED bulb, spaced apart from the metal LED board, and controlling color and brightness of the LED.
