摘要： This invention relates to white and coloured dot-matrix and segmented displays in which the colour is produced by means of blue or ultra-violet light-emitting diodes (LED) together with a wavelength conversion phosphor, or combination of phosphors. A white or coloured dot-matrix display is produced by conversion of blue or Ultra-Violet light from an array of light-emitting diodes (LEDs) 1 by means of a layer of phosphor 5 applied to a substrate 4 so as to provide uniform illumination over the areas 8 . In comparison to the previous art the invention improves the uniformity and consistency of illumination over the illuminated areas of the display and also improves reliability by distancing the phosphor layer 5 from the dissipation generated by the LEDs 1 .

摘要： One or more light-emitting diodes (LEDs) 1 are hard-wired to a connector 2 through a mechanical/electrical interface 3. The interface 3 provides mechanical support, electrical connection and thermal connection, and includes in particular a charge storage component such as a capacitor 4. The interface will in general also include additional circuit components 5 such as resistors or protection devices. In one implementation the connector is connected directly to the external wiring 6 without the need for any additional connectors. The invention reduces the peak current drawn by the LED to allow replacement of conventional combinations of filament lamp and lampholder for pulse operation. Such pulse operation may be used to address a large number of LEDs sequentially or by matrix addressing, and can also be used to control the light output from the LED by changing the pulse length.

摘要翻译：一个或多个发光二极管（LED）1通过机械/电气接口3硬连接到连接器2.接口3提供机械支撑，电连接和热连接，并且特别包括电荷存储组件，例如电容器4.该接口通常还包括诸如电阻器或保护装置的附加电路部件5。在一个实施方式中，连接器直接连接到外部布线6，而不需要任何附加的连接器。本发明降低了由LED吸收的峰值电流，以允许更换常规的灯丝灯和灯座组合用于脉冲操作。这种脉冲操作可以用于顺序地或通过矩阵寻址来寻址大量的LED，并且还可以用于通过改变脉冲长度来控制来自LED的光的输出。
