Description

Illuminating device with sensor

This creation relates to a lighting device.

In general, the illuminating device of the luminaire, such as a bulb, a lamp tube, etc., is provided with a sensor and a controller on the luminaire, and the brightness of the environment is detected by the sensor to switch the illuminating device. For example, when the sensor detects less light and causes the controller to judge that the brightness of the environment is dark, a signal is sent to cause the light-emitting device to emit light; when the sensor detects more light, the controller determines When the brightness of the environment is sufficiently bright, a signal is emitted to turn off the illumination device. In order to make the environment detected by the sensor the same as the light-emitting device, the sensor can be directly disposed in the light-emitting device.

However, in the existing illuminating device with an inductor, the illuminating element is very close to the inductor, so that the light emitted by the illuminating element directly illuminates the sensor. In other words, when the brightness of the environment is dark, the sensor and the controller cause the light-emitting element to emit light. At this time, the light emitted by the light-emitting element causes the sensor to receive more light, so that the controller determines that the brightness of the environment is sufficiently bright, so that The light emitting element is turned off. Therefore, the illuminating device still cannot emit light under the correct brightness of the environment.

In view of this, providing a better improvement solution is an urgent problem to be solved in the industry.

Therefore, the present invention provides an opaque partition between the illuminating element and the control circuit so that the light emitted by the illuminating element cannot penetrate the partition without affecting the control circuit on the other side of the partition. sensor. Therefore, the light received by the sensor of the control circuit is the ambient light, so that the control circuit can detect the dark environment to activate the light-emitting component, and after the light-emitting component is activated, the light emitted by the light-emitting component does not illuminate.
