Precise induction control method of infrared induction night light and night light

Abstract

The invention discloses a precise induction control method of an infrared induction night light. The precise induction control method comprises the steps as follows: the infrared induction night light is arranged; an infrared lens is matched with a pyroelectric infrared sensor and a specific induction area is formed outwards; according to the induction area, an axial median line of a light shell is taken as a center line; the included angle between an induction line on the edge of the outer side of the induction area and the center line is 50-60 degrees; the infrared induction night light is arranged at the position of which the horizontal distance to a body of a user is 0.5-1.5m on roughly the same horizontal plane when the body of the user lies on the back; and when the user hands up or stands up, an infrared ray sent out by the user enters the specific induction area of the night light and the night light can be lighted up. The invention further discloses the infrared induction night light of implementing the method. Through the specific induction area, the night light can be lighted up when a human body hands up at night, so that induction is accurate; a maloperation is not generated; and the infrared induction night light is especially suitable for being applied to a mother-and-baby bedroom.

Description

technical field [0001] The invention relates to the field of induction lamps, in particular to a precise induction control method for an infrared induction night lamp and the night lamp. Background technique [0002] The sensor night lights on the market are usually used for indoor lighting at night, such as doorways, aisles, stairs, bedrooms, etc., and can also be used in dimly lit places, such as storage rooms, wardrobes, etc. However, when it is used as a bedside lighting in a bedroom, especially as a night light for mothers and babies, the following problems will occur: [0003] 1) With lateral sensing, the user cannot precisely control the light on or off through the sensing area. see figure 1 , figure 2 As shown, the existing night light generally includes an electric light source and a control circuit for controlling the power on and off of the electric light source, and an infrared human body sensor connected to the control circuit. The infrared human body sensor...

Problems solved by technology

[0003] 1) With lateral sensing, the user cannot precisely control the light on or off through the sensing area

see figure 1 , figure 2 As shown, the existing night light generally includes an electric light source and a control circuit for controlling the power on and off of the electric light source, and an infrared human body sensor connected to the control circuit. The infrared human body sensor includes a pyroelectric infrared sensor 10 and an infrared lens 30 Wherein, the pyroelectric infrared sensor 10 is generally located inside the housing 20, and the infrared lens 30 is arranged outside the pyroelectric infrared sensor 10 and covers the pyroelectric infrared sensor 10; the pyroelectric infrared sensor 10 is placed laterally Afterwards, form a lateral hemispherical sensing region that expands out with the side as the reference surface, and form a hemispherical fan sensing region 40 with the pyroelectric infrared sensor 10 as the center of the circle on the outer surface of the night light (the effective sensing distance is generally 5-6 meters), when any part of the human body enters the sensing area, the night light will light up, but it cannot be triggered only by the user's specific body position or human body parts, and it is easy to receive signals from air conditioners, heat sources, and light sources. and other interference signals, resulting in malfunction;

[0004] 2) see image 3 , Figure 4 As shown, in the existing night light with a human body sensor installed horizontally, if the fan-shaped sensing area 40 covers the bed 50, when the user 60 on the bed has activities such as normal turning over and horizontal movement, the night light 100 will be activated. Misoperation, light up;

like Figure 7 , Figure 8 As shown, the problem of the direct-light type is that the distance between the LED light source 70 and the astigmatism or the transparent lampshade 80 is too close, so that the light cannot be fully scattered by the lampshade, resulting in local overbrightness and glare, which is particularly obvious at night, especially for mothers and infants. To protect the eyes of infants and young children, the light should not be too strong, and the existing night lights cannot meet this requirement; Figure 9 , Figure 10 As shown, the side-firing type can solve the problem that the light from the light source directly hits the human eye, but because the light-emitting surface is narrow, the light is only concentrated next to the night light, and the light is not received from the front, so the overall lighting effect of the room is poor

[0007] 5) Most of the luminous colors or patterns of existing night lights are fixed, which cannot be adjusted according to environmental needs or personal preferences, and cannot adapt to people's individual needs; at the same time, night lights are only used as a lighting fixture and have no decorative function
