Light source with replaceable lamp wick

The utility model discloses an illuminant apparatus of which the lamp wick is removable. The plug-in type replacement can be adopted for the change of the lamp wick tube, so shat the problem concerning the calibration and location of the two reflectors for both the lamp wick and the lamp screen can not be considered. The illuminant is equipped with the grip. So, the system will not be contaminated as conducting the replacement with the hands. The smooth axis of the illuminant forms the vertical position with the lamp tube, so as to avoid the dark field in the middle position. Meanwhile, the lamp can be free from the non-uniformity of heating. Thus, illuminant blinking arising from the poor thermal balance can be avoided. The end of the lamp wick tube is covered by the sheet copper, so as to improve the electrifying and the heat rejection. The two reflector surfaces are fixed at a relative position so as to improve the problem concerning the location of two reflector surfaces as replacing ...

Light source with one-way lamp wick

The utility model discloses an illuminant apparatus of which the unidirectional lamp wick is available. The plug-in type replacement can be adopted for the change of the lamp wick tube, so shat the problem concerning the calibration and location of the two reflectors for both the lamp wick and the lamp screen can not be considered. The illuminant is equipped with the grip. So, the system will not be contaminated as conducting the replacement with the hands. The smooth axis of the illuminant forms the vertical position with the lamp tube, so as to avoid the dark field in the middle position. Meanwhile, the lamp can be free from the non-uniformity of heating. Thus, illuminant blinking arising from the poor thermal balance can be avoided. The end of the lamp wick tube is covered by the sheet copper, so as to improve the electrifying and the heat rejection. Two electrodes of the lamp bulb are leaded out from the same direction; the filming area of the reflector can be increased, so as to enlarge ...

A method and corresponding device for quick setup of grey value-brightness curve of the display

The invention relates to a method for quickly building a gray value-brightness curve of a display. Part of gray values and corresponding brightness values of the display is obtained and then substituted to a formula for calculation; the variables in the formula are relieved to obtain a gray value-brightness curve.
