Description

Sensor light

technical field

The utility model relates to an induction lamp, in particular to an induction lamp which can be automatically turned on and off by light induction or can have a certain auxiliary brightness.

technical background

There are generally two ways of traditional pyroelectric body sensor lights. There is only one light source in the light-controlled induction lamp. When someone moves or approaches, the lamp lights up. After the person leaves, the lamp will automatically turn off after a certain time delay. Another induction lamp contains two light sources, the main light source and the auxiliary light source. If there is no activity in the sensing area, the auxiliary light source will always be on. When someone moves or approaches, the main light source will be on and the auxiliary light source will continue to light On, after the person leaves, the main light source will automatically turn off after a certain time delay.

The light-controlled induction lamp has no auxiliary lighting. When people move outside the sensing area or slowly enter the sensing area outside the sensing area, they will not be illuminated, which is very inconvenient. Although the second type of induction lamp has auxiliary lighting, it needs two light sources, which is large in size and high in cost. Generally, it is only suitable for incandescent lamps, not for other light sources such as energy-saving lamps.

The light will be on when human activity is sensed, and the light will be off when there is no human activity, so the light will be turned on and off frequently. If the energy-saving lamps are switched on and off frequently, the life of the lamps will be seriously affected. Therefore, one of the most important fatal defects of the traditional induction lamp is that the light source of the induction lamp must be an incandescent lamp or a tungsten halogen lamp. The luminous efficiency of incandescent lamps and tungsten halogen lamps is generally 10lm/W, which is far lower than the 70lm/W of energy-saving lamps, so traditional induction lamps are not energy-saving and environmentally friendly.

Utility model content

The technical problem to be solved by the utility model is to provide an induction lamp, which can realize auxiliary lighting and main lighting with only one light source.

The technical solution adopted by the utility model is: an induction lamp, including a lamp housing, a light source installed in the lamp housing, and an infrared sensing device for sensing whether there are people in a certain range around the lamp, and the light source is always on The light source; and the induction lamp also includes a light control induction device that lights up or closes the light source according to the change of the natural light brightness of the surrounding environment of the lamp, and is connected with the infrared induction device to send a control signal according to the induction signal of the infrared induction device to adjust the The control circuit module of the light brightness of the light source, the control circuit module includes a signal receiving and processing circuit connected with the infrared sensing device to receive the sensing signal sent by the infrared sensing device and process the corresponding control signal, and the signal The receiving and processing circuit is connected to adjust the brightness of the light source according to the control signal of the signal receiving and processing circuit, and the delay circuit is connected to the brightness adjusting circuit to control the working time of the brightness adjusting circuit.

The technical effect achieved by the utility model is: the sensor lamp of the utility model has only one light source, which has both auxiliary lighting and main lighting. In the lighting state, if the person is not in the sensing area, the light source will still have a certain light brightness, so as to have the auxiliary lighting function, and its brightness can generally be set to about 50% when it is fully bright. When the activity of people is sensed, the light will be fully lit to realize the main lighting; again, when using energy-saving lamps, since the lights are not turned on and off frequently, the brightness and life of the lights will not be affected; in addition, it can use incandescent lamps, Halogen tungsten lamps, ordinary energy-saving lamps, LED lamps and other traditional light sources and energy-saving, green and environmentally friendly light sources.

The utility model will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

Detailed ways

The induction lamp of the utility model comprises a lamp housing, a light source installed in the lamp housing, an induction device installed outside or inside the lamp housing and a control circuit module arranged in the lamp housing.

As shown in Figure 1, the sensing device includes a light control sensing device for turning on or off the light source according to changes in the natural light brightness of the surrounding environment of the lamp and an infrared sensing device for sensing whether there are people around the light source. It is used to control the opening and closing of the light source; and the infrared sensing device is used to control the brightness of the light source. There is no substantial difference in the sensing principle between the infrared sensing device and the infrared sensing device of the existing infrared sensing lamp. When someone is active, an induction signal is sent to the control circuit module.

The control circuit module includes a signal receiving and processing circuit for receiving the sensing signal of the infrared sensing device, a brightness adjusting circuit connected with the signal receiving and processing circuit, and a delay circuit connected with the brightness adjusting circuit. The signal receiving and processing circuit is connected with the infrared sensing device, which sends a control signal to the main delay circuit of the brightness adjustment circuit according to the sensing signal received and transmitted from the infrared sensing device, and the brightness adjustment circuit controls and increases the light brightness of the light source , and the delay circuit works at the same time. When the delay circuit reaches the set time length, the delay circuit will send a control signal to the brightness adjustment circuit, and the brightness adjustment circuit will stop working or be adjusted by the brightness adjustment circuit to make the light source The brightness of is restored to the original brightness or turned off again. In specific use, when the light control sensing device senses that the surrounding natural light brightness is low, it will send a signal to the control circuit module to light up the light source, and when the surrounding natural light brightness returns to a certain brightness, it will send a signal again. Give the control circuit module, thereby controlling to turn off the light source. During the period when the light source is turned on for lighting, if the infrared sensing device senses that there are people around, it will also send a signal to the control circuit module, thereby enhancing the brightness of the light source to realize the main lighting function. After a certain time delay, the brightness will resume again. Return to the initial brightness to realize the auxiliary lighting function.

In order to facilitate the setting and adjustment of the initial brightness of the sensor light source (that is, the brightness of the light when the auxiliary light is on), the control circuit module also includes a brightness setting circuit for controlling the initial brightness of the light source, and correspondingly has an access The above brightness setting circuit is used to adjust the knob for setting the initial brightness of the light source. When the adjustment knob is adjusted, a setting parameter signal is also sent to the brightness setting circuit, and the brightness setting circuit changes the initial brightness of the light source accordingly according to the parameter signal. Certainly, as shown in FIG. 2 , the brightness setting circuit is directly connected to the brightness adjustment circuit, and the brightness is adjusted to the set initial brightness through the brightness adjustment circuit.

The induction lamp can use various light sources, for example: incandescent lamp, tungsten halogen lamp, ordinary energy-saving lamp, LED lamp and so on.

The sensor lamp of the utility model has only one light source, which has both auxiliary lighting and main lighting. On the one hand, it can decide whether to turn on or turn off the light source according to the brightness of the surrounding natural light, and can also sense whether there are people around to decide whether to adjust the brightness of the light; In the lighting state, if the person is not in the sensing area, the light source will still have a certain brightness, so that it has the auxiliary lighting function. Generally speaking, considering the energy saving and ensuring the basic auxiliary lighting needs, the brightness can be set It is better to have a brightness not greater than 50% at full brightness, and it is usually set to 50%; the light is fully lit to realize the main lighting when the movement of people is sensed; again, when using energy-saving lamps, because there is no frequent turning on of lights, Turning off the light will not affect the brightness and life of the light; in addition, it can use various traditional light sources such as incandescent lamps, tungsten halogen lamps, ordinary energy-saving lamps, and LED lights, as well as energy-saving and green light sources, which are green and environmentally friendly.
