Wide-area luminaire with separate control illumination

The invention relates to the technical field of luminaires, in particular to an innovative improvement of a wide-area luminaire with separate control illuminance.

At present, most of the lamps on the market are set as simple switch control. The disadvantages of lamps using this simple switch operation are that they are too bright, insufficient brightness, or use manual control operation and power consumption, and even affect consumers' poor eyesight. Or bad problems, and the way to solve it can only increase or decrease the number of lamps used.

Later, the industry introduced a method of changing the brightness through the control of the external circuit, and achieved through two ways, one is to increase the number of segments, such as 100%, 75%, 50%, 25% brightness, so that the user can choose the appropriate The brightness of the other is that the brightness can be freely selected by means of the operation knob or electronic control; the common disadvantage of the two methods is that the human body needs to be actively adjusted, and when the external environment has brightness When changing, such a luminaire cannot actively adjust the brightness according to the change of brightness after the ambient light is added; for example, the new patent of the luminaire with illuminance indication or illuminance adjustment function of the Republic of China Announcement No. M279801, the luminaire is used. Whether you want to be brighter or darker, you have to take the initiative to make adjustments. It is more troublesome and inconvenient to use.

Later, the industry improved the situation and automatically adjusted the brightness of the space by means of automatic sensing instead of the light source or The illuminance within the effective illumination range of the luminaire is adjusted. In this case, because the auto-sensing cannot be effectively locked in the illumination range, subsequent actions may be misjudged, such as automatic enhancement or reduction of brightness, or irregular brightness. Changes, when such a situation occurs, will put a burden on the user's vision.

Therefore, how to illuminate the brightness of the above-mentioned conventional lamp structure needs to be inconvenient to be manually adjusted by the consumer, and the illumination in the effective illumination range of the light source or the lamp cannot be adjusted to cause a misjudgment in the brightness adjustment operation.
