Description

Adjustable brightness lamp

The invention relates to a lamp, in particular to an adjustable brightness lamp capable of detecting ambient light and supplementing brightness.

Existing luminaires used to illuminate indoor environments, such as ceiling lamps or illuminators, are equipped with luminaires on the top of the room, and the switches on the wall are used by the user to control whether the lamps are bright or not lit. The effect of ambient lighting.

Although the above-mentioned existing lighting fixtures for lighting environments can be used for indoor lighting, the brightness of the lamps is fixed, when the wall is provided with floor-to-ceiling windows that can introduce sunlight, or when other natural and artificial light sources are used to illuminate the indoor environment. Since the existing lamps cannot adjust the brightness, there is a lack of indoor lighting or the effect of the indoor environment lighting after turning on, and the situation of wasting energy is in vain.

Because the existing lamps can not adjust to the indoor ambient light. To this end, the novel uses the means for detecting ambient light to automatically control the brightness of the illumination structure, thereby achieving the effect of automatically turning on the illumination structure and adjusting the light in the control room.

In order to achieve the above creative purpose, the present invention provides an adjustable brightness lamp, comprising a controller and an illumination structure electrically connected to the controller, a motion sensor, and an ambient light sensor, wherein:

Setting a brightness setting value in the controller, when the controller receives the signal that the motion detector detects the action, the controller captures the value detected by the ambient light sensor, if the ambient light sensor The value detected by the device is lower than the brightness setting value, and the controller gradually brightens the light emitted by the illumination structure to a value detected by the ambient light sensor to meet the brightness setting value.

Further, when the controller of the present invention does not capture the signal that the motion detector detects the motion within a time setting value, the controller gradually dims the light emitted by the illumination structure to be turned off.

Furthermore, the illumination structure of the present invention is a lamp tube, a power saving bulb, an LED bulb or a halogen bulb.

When the present invention is used, the lighting structure is installed on a ceiling or a wall of an indoor space. When a person enters the indoor space, the motion detector detects an action and sends a signal to the controller, and the control is performed. The device captures the value of the ambient light detected by the ambient light sensor, and compares the value with the set brightness setting value. If the ambient light value exceeds the brightness setting value, the device does not operate, if the ambient light value is low. At the brightness setting value, the illumination light of the illumination structure is illuminated until the value of the ambient light conforms to the brightness setting.

By means of the novel detectable human activity and the comparison of the value of the ambient light with the configuration of the brightness setting value, the person can have good illumination as soon as he enters the indoor environment, and at the same time, can avoid the situation that the indoor environment is bright enough to turn on the light, It achieves the effect of automatically dimming the light to the proper brightness with the indoor environment, and avoiding unnecessary lighting to save energy.

In order to understand the technical features and practical effects of the present invention in detail, it can be implemented in accordance with the contents of the specification, and further described in detail with reference to the preferred embodiments shown in the drawings.

The preferred embodiment of the present invention, as shown in FIG. 1 , is an adjustable brightness lamp, and is provided with a controller 10 and an illumination structure 11 , a motion sensor 12 , and an environment respectively electrically connected to the controller 10 . Light sensor 13, wherein:

The controller 10 sets a brightness setting value 101 and a time setting value 102, which may be any value sufficient to illuminate the room. For example, according to the CNS standard, the office illuminance is 750 to 1000 illuminance (LUX). The illumination of the auditorium, the hall, and the reception room is between 200 and 300 illuminance (LUX), and the brightness setting value 101 can be set according to the brightness (illuminance) required by the new installation place.

The lighting structure 11 can be a light tube, a power saving light bulb, an LED light bulb or a halogen light bulb, and the light tube, the power saving light bulb, the LED light bulb or the halogen light bulb used in the lighting structure 11 is not limited to one, and may be a plurality of light tubes, a power saving light bulb, A combination of an LED bulb or a halogen bulb, the Motion Sensor can be a Passive Infrared Sensor (PIR), and the ambient light sensor 13 can use a brightness sensor or illumination composed of a photoresistor. meter.

When the controller 10 receives the signal that the motion sensor 12 detects the motion, for example, when the motion sensor 12 detects the activity of a person in the environment, a signal is sent to the controller 10, and then the controller 10 The controller 10 captures the value detected by the ambient light sensor 13. If the value detected by the ambient light sensor 13 is lower than the brightness set value 101, the controller 10 gradually brightens the illumination structure 11. The value detected by the light to the ambient light sensor 13 conforms to the brightness set value 101. When the controller 10 does not receive the signal that the motion sensor 12 detects the human motion within the time setting value 102, for example, 3 minutes, 5 minutes, or 30 minutes, the controller 10 gradually dims the illumination. Construct the light from 11 to off.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. All other equivalent changes or modifications which are not departing from the spirit of the present invention are included in the present invention. Within the scope of the patent application.
