[0031] The focusing lens 2 and the light sensor 7 are arranged correspondingly, the focusing lens 2 is used to collect light outside the housing 1, and the light sensor 7 is used to sense the changes in the light collected by the focusing lens 2. The focusing lens 2 and the light sensor 7 are fixed simultaneously by the housing 1, so that they are fixed simultaneously by the housing 1, the accuracy of positioning and matching, and the consistency in mass production are ensured, and the problem of inaccurate positioning of the two existing parts due to installation tolerances during installation is avoided by fixing the focusing lens 2 and the light sensor 7 separately by two different parts. Part of the focusing lens 2 is arranged in the through hole 102 (that is, a part of the focusing lens 2 is located in the through hole 102 and a part is located in the housing 1), so that the focusing lens 2 collects light outside the housing 1. It should be noted that in this embodiment, the fixing method of the focusing lens 2 and the housing 1 is not specifically limited, and it can be fixed by various methods such as bonding and clamping.

In addition, the shape of the protruding cavity 105 is different from that of the sealing plate 4, and the protruding cavity 105 is used as an anti-reverse structure to prevent users from installing incorrectly.

[0034] In one embodiment, Figure 1 , Figure 2 As shown, the condenser lens 2 partially extends out of the bottom plate 104 to collect light outside the housing 1 .

[0035] In one embodiment, Figure 1 , Figure 2As shown, the cross section of the condenser lens 2 is an arc.

The condenser lens 2 collects ambient light within a specified range, and the ambient light is refracted into parallel light through the condenser lens 2 and transmitted to the light sensor 7 through the plane 202.

[0036] In one embodiment, Figure 1 , Figure 2 As shown, the optical sensor 7 further includes a PCB board 3, which is disposed in the accommodation space 106. The PCB board 3 is provided with a mounting hole, and the pins of the optical sensor 7 are fixed to the PCB board 3 after passing through the mounting hole. The optical sensor 7 is further fixed by the PCB board 3 to ensure the stability of the optical sensor 7 during use. In addition, the signal of the optical sensor 7 is transmitted to the PCB board 3 through the pins.

[0037] In one embodiment, Figure 3 , Figure 4 As shown, it also includes a sealing plate 4, the shell 1 has an opening, the sealing plate 4 is used to close the opening, the sealing plate 4 is provided with a socket 401, and the surface of the PCB board 3 facing away from the accommodating space 106 is provided with a power supply pin 301, the power supply pin 301 is arranged through the socket 401, and the power supply pin 301 is used to supply power to the PCB board 3.

[0038] In this embodiment, if Figure 3 , Figure 4 As shown, a signal pin 302 is further provided on the surface of the PCB board 3 facing away from the accommodating space 106 . The signal pin 302 is arranged through the plug hole 401 , and the signal pin 302 provides signal transmission between the PCB board 3 and the lamp.

[0039] In one embodiment, Figure 1 , Figure 3 , Figure 4 As shown, it also includes a plug-in block 6, which is fixedly connected to the sealing plate 4, and the power pin 301 is arranged through the plug-in block 6. A receiving portion 402 is respectively provided on both sides of the sealing plate 4, and each receiving portion 402 accommodates a magnetic component 5. Specifically, the magnetic component 5 is a magnet. It should be noted that the plug-in block 6 is arranged on the side of the sealing plate 4 away from the PCB, and the plug-in interface and the sealing plate 4 are detachably connected by means of plug-in, clip-on, bonding, etc. In addition, in this embodiment, the shape of the magnetic component 5 is not specifically limited, and it can be in various forms such as cylindrical and rectangular. Figure 3 , Figure 4 The magnetic attraction member 5 shown is cylindrical, and the accommodation portion 402 is arc-shaped to match the magnetic attraction member 5 .

[0040] In this embodiment, if Figure 3As shown, welding ends 403 are respectively provided at both ends of the sealing plate 4, and ultrasonic welding of the sealing plate 4 and the housing 1 is achieved through the welding ends 403, thereby ensuring the stability of the components in the entire light sensor.

[0041] A lamp, comprising the above-mentioned light sensor, such as Figure 5 , Figure 6 As shown, it also includes a lamp housing 8, and the light sensor is detachably connected to the side wall of the lamp housing 8, that is, the plug-in block 6 of the light sensor extends into the side wall of the lamp housing 8, the magnetic component 5 is magnetically connected to the side wall of the lamp housing 8, and the power supply pin 301 is inserted into the lamp housing 8 to draw power. The plug interface, the magnetic component 5 and the power supply pin 301 work together to ensure the stability of the connection between the light sensor and the lamp housing 8 on the one hand, and to facilitate users to install, maintain and replace them by themselves on the other hand. In this embodiment, the lamp housing 8 is fixed on the roof. The material of the lamp housing 8 is iron. A light sensor is arranged on the side of the lamp housing 8. The light sensor collects ambient light within a certain range in the house through a focusing lens 2. When the ambient light changes, the light sensor 7 converts the collected light signal fluctuations into electrical signal fluctuations. After the ADC of the single-chip microcomputer on the PCB board 3 collects the fluctuating electrical signal, the dimming function is realized through the DALI dimming circuit (Digital Addressable Lighting Interface) of the lamp according to the dimming algorithm.

[0042] A method for using a light sensor comprises the following steps:

[0043] (1) The light sensor sets a threshold value. When working, it collects the average value of the ambient light through the focusing lens 2 and the PCB board 3 analyzes it. When this value exceeds the set threshold range, the dimming function will be triggered to achieve intelligent, energy-saving and comfortable effects.

[0044] (2) The light sensor will capture fluctuations in ambient light. When there are no moving users around, this function will not be triggered and the light will be maintained at a relatively dim brightness to achieve energy saving. When an animal or user walks into the sensing range of the light sensor, the light will hit the animal and reflect light. The intensity change of the reflected light will be received and amplified by the focusing lens 2 of the light sensor and then converted into an electrical signal to brighten the brightness of the lamp. In the whole process, the light changes softly and slowly, which will not make the user feel abrupt or uncomfortable.

[0045] The light sensor and lamp provided by the present invention have the following advantages: (1) the focusing lens 2 is extended outside the shell 1, so that light from different directions outside the shell 1 can be collected; (2) the focusing lens 2 and the light sensor 7 are fixed by the shell 1 at the same time, ensuring the accuracy of the positioning and matching of the two, and achieving consistency in mass production; (3) the light sensor 7 is further fixed by the PCB board 3, ensuring the stability of the light sensor 7 during use, and transmitting it to the PCB board 3 through the pins; (4) the light sensor is connected to the lamp housing 8 by magnetic attraction + plug-in, which ensures the stability of the connection while achieving detachability.

[0046] As an alternative implementation, Figure 7 As shown, the present application may not be provided with the plug-in block 6, and the power and signal are connected with the lamp housing 8 by means of a POGO PIN. Different forms are used to adapt to different lamps.

[0047] As an alternative implementation, the condenser lens 2 may not extend out of the housing 1 , that is, the condenser lens 2 is flush with the outer surface of the bottom plate 104 , or the condenser lens 2 is retracted into the through hole 102 .
