Embodiment Construction

[0037] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0038] Please refer to figure 2 , figure 2It shows the situation when using the lamp 100 according to an embodiment of the present invention for lighting, and X, Y, and Z in the figure respectively represent three mutually perpendicular directions. The lamp 100 has multiple light-emitting modules, for example, the lamp 110 has three light-emitting modules 110, 120 and 130. The design of the lamp 100 adopts the concept that different light-emitting modules can have different dimming ratios. In detail, the lamp 100 has three light emitting modules 110, 120 and 130 respectively corresponding to the lighting areas 22, 24 and 26 of the desktop 20, wherein the illuminance in the lighting areas 22, 24 and 26 will be at 200 lumens The above, but the present invention is n...

Abstract

The invention provides a lamp, which comprises a first illumination module, a second illumination module and a control circuit, wherein the first illumination module is provided with a first light outlet surface; the second illumination module is provided with a second light outlet surface; the second light outlet surface is connected with the first light outlet surface; the first light outlet surface corresponds to a message device use region; the second light outlet surface corresponds to a reading-writing region. The control circuit is coupled with the first illumination module and the second illumination module, wherein when the control circuit increases the brightness of the first illumination module and the second illumination module, the brightness increase proportion of the first illumination module is smaller than that of the second illumination module, so that the illumination degree of the message device use region is lower than the illumination degree of the reading-writing region.

Description

technical field [0001] The invention relates to a lamp, especially a lamp with light-emitting modules with different dimming ratios. Background technique [0002] In today's working environment, screens are widely used and almost replace paper as the main medium for displaying information, and this screen-based working environment is called Visual Display Terminal (VDT). ANSI / HFS 100 (American National Standards Institute / Human Factors Society 100) recommends an illuminance of 300 to 500 lumens (lux) for a VDT environment. Please refer to figure 1 , figure 1 It shows the situation when a known lamp 10 is used for lighting. When the lamp 10 is used on the desktop 20, and the height H from the table 20 is 50 cm, the illuminance of the lamp 10 in the lighting area 12 is above 200 lumens, which meets the VDT ambient illuminance recommended by ANSI / HFS 100, where The length L1 of the lighting area 12 is about 50 cm. However, the illuminance of the desktop 20 outside the ligh...
