[0001] The invention relates to the technical field of energy-saving lamps, in particular to a control method for an LED energy-saving lamp and an energy-saving lamp. Background Art

[0002] Desk lamps are items that people often use in daily life. When working in an environment with poor light intensity, desk lamps are often needed as lighting sources. The existing desk lamps on the market have a small lighting range and strong directionality. As a result, when using a desk lamp, if you temporarily leave the desk lamp area, additional lighting tools are needed in the area near the desk lamp.

[0003] With the development of science and technology, desk lamps with dual sound and light control have appeared on the market. By connecting the sound sensor and the light sensor to the sound and light controller to control the switch of the desk lamp, automatic switch control of the desk lamp can be achieved to avoid energy waste. However, during use, if you read or work quietly under the desk lamp, the sound sensor cannot accurately capture the sound information, which will cause "misjudgment" and cause the delay circuit to automatically shut down after a period of time, affecting the user's normal use.

[0004] In view of the small illumination range of the above-mentioned desk lamp and the "misjudgment" problem of the sound and light dual-control energy-saving desk lamp, the present invention proposes a control method and an energy-saving lamp for LED energy-saving lamps, which solves the problem that when reading or working quietly under the energy-saving desk lamp, the sound sensor cannot accurately capture the sound information, causing the delay circuit to automatically shut down after working for a period of time.

[0015] In the above-mentioned control method of an LED energy-saving lamp, the method further includes: in response to the first switch being closed and the second switch being closed, the energy-saving lamp is lit, otherwise, the energy-saving lamp is turned off.

[0016] In the above-mentioned control method of an LED energy-saving lamp, the control of the adjustment device to expand or reduce the lighting range according to the sound intensity includes: dividing the sound signal into different intervals according to the intensity; assigning the volume value of the sound sensor to the corresponding interval; and setting different working states of the adjustment device in response to different intervals.

[0032] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0033] Scenario Overview

[0034] As mentioned above, due to the small illumination range and strong directionality of the energy-saving desk lamps currently on the market, if you temporarily leave the area of ​​the energy-saving desk lamp when using it, additional lighting tools are needed in the area near the energy-saving desk lamp. In addition, during the use of the energy-saving desk lamps with dual sound and light control on the market, if you read or work quietly under the energy-saving desk lamp, the sound sensor cannot accurately capture the sound information, which will cause "misjudgment", causing the delay circuit to automatically shut down after a period of time, affecting the normal use of the user. Therefore, we need an energy-saving desk lamp that can appropriately expand the illumination range without "misjudgment".

[0035] Based on this, the present application proposes a control method for an LED energy-saving lamp, which includes: obtaining the ambient brightness value detected by a photosensitive sensor; obtaining the infrared signal of human body radiation in the nearby area detected by an infrared sensor; obtaining the sound signal of the ambient environment detected by a sound sensor; performing an OR operation on the infrared signal and the sound signal to obtain a first value; setting a critical value of light brightness; comparing the ambient brightness value with the critical value of light brightness to obtain a second value; controlling the opening and closing state of a first switch according to the first value, and controlling the opening and closing state of a second switch according to the second value; and controlling the operation of an adjustment device to expand or reduce the illumination range according to the sound intensity.

[0036] Figure 1 The figure illustrates an application scenario diagram of an LED energy-saving desk lamp according to an embodiment of the present application.

[0037] like Figure 1 As shown, in this application scenario, the adjustment device (for example, Figure 1 A) according to the received sound sensor (for example, Figure 1 The size of S) is controlled by controlling the second lampshade (for example, Figure 1 L) in the first lampshade (eg, Figure 1 The outer surface D) shown in FIG. 1 moves up and down.

[0038] Exemplary Methods

[0039] Figure 2 The figure shows a flow chart of a control method for an LED energy-saving lamp. Figure 2As shown, a method for expanding the illumination range of a dual-control light source according to an embodiment of the present application includes: S110, obtaining the ambient brightness value detected by a photosensitive sensor; S120, obtaining an infrared signal of human body radiation in a nearby area detected by an infrared sensor; S130, obtaining a sound signal of the ambient environment detected by a sound sensor; S140, performing an OR operation on the infrared signal and the sound signal to obtain a first value; S150, setting a critical value of light brightness; S160, comparing the ambient brightness value with the critical value of light brightness to obtain a second value; S170, controlling the opening and closing state of a first switch according to the first value, and controlling the opening and closing state of a second switch according to the second value; and, S180, controlling the operation of an adjustment device to expand or reduce the illumination range according to the sound intensity.

[0040] In step S110, the brightness value of the surrounding environment detected by the photosensor is obtained, that is, the light signal is converted into an electrical signal through the photosensor, and the light intensity value is reflected as the size of the electrical signal. In a specific implementation, the photosensor can adopt a visible light sensor SMD type LXD / GB5-A1DPZ (package SMD1206).

[0041] In step S120, the infrared signal of human body radiation in the nearby area detected by the infrared sensor is obtained, that is, the infrared sensor is used to detect whether there is a person nearby. In a specific implementation, the infrared sensor can be a P228 pyroelectric infrared sensor.

[0042] In step S130, a sound signal of the surrounding environment detected by a sound sensor is obtained. In a specific implementation, the sound sensor may be a TZ-2KA noise sensor, which can be used to detect the presence of environmental sound and determine the magnitude of the sound intensity.

[0043] In step S140, the infrared signal and the sound signal are subjected to an OR operation to obtain a first value. In a specific implementation, the infrared sensor detects the presence or absence of an infrared signal, and records it as 1 if it is present, and 0 if it is absent. The sound sensor detects the presence or absence of a sound signal, and records it as 1 if it is present, and 0 if it is absent. The infrared signal and the sound signal are subjected to an OR operation, that is, when the infrared signal is 1 or the sound signal is 1, the output result is 1, that is, the first value is 1, otherwise the output result is 0.

[0044] In step S150, a critical value of light brightness is set, that is, a critical value of light brightness at which the light is insufficient and an energy-saving desk lamp is required to illuminate the room.

[0045] In step S160, the ambient brightness value is compared with the light brightness critical value to obtain a second value, that is, the light brightness detected by the photosensor is compared with the set light brightness critical value. If the light brightness detected by the photosensor is less than the set critical value, it is recorded as 1, that is, the second value is 1, otherwise it is recorded as 0.

[0046] In step S170, the opening and closing state of the first switch is controlled according to the first value, and the opening and closing state of the second switch is controlled according to the second value, that is, when the first value is 1, the first switch is controlled to be closed, when the first value is 0, the first switch is controlled to be open, when the second value is 1, the second switch is controlled to be closed, and when the second value is 0, the second switch is controlled to be open.

[0047] In step S180, the control and adjustment device is operated to expand or reduce the illumination range according to the sound strength. That is, when the sound signal is strong, the control and adjustment device is operated to expand the illumination range, making it convenient for people to use energy-saving desk lamps in environments with poor light intensity. When the sound signal is weak, the control and adjustment device is operated to reduce the illumination range, thereby reducing the consumption of electric power resources and improving the energy efficiency of the device.

[0048] Exemplary Devices

[0049] According to an embodiment of the present application, an LED energy-saving desk lamp includes: a lamp fixture, including a lamp holder, a lampshade and a lamp post connecting the lamp holder and the lampshade, the lamp post being a movable part, and a lighting element being arranged inside the lampshade; a photosensitive sensor for obtaining the brightness value of the surrounding environment; a sound sensor for detecting sounds in the surrounding environment; an infrared sensor for obtaining infrared signals radiated by human bodies in nearby areas; a processor for processing the outputs of the photosensitive sensor, the sound sensor and the infrared sensor; a switching circuit for controlling the on and off state of the energy-saving desk lamp; and an adjusting device for adjusting the illumination range of the energy-saving desk lamp.

[0050] In one example, in the above-mentioned LED energy-saving desk lamp, a light intensity critical value is preset in the processor, and the output of the photosensor is compared with the light intensity critical value in the processor, and the comparison result is obtained as a second value.

[0051] In one example, in the above-mentioned LED energy-saving desk lamp, the switch circuit includes a first switch and a second switch, and the first switch is connected in series with the second switch.

[0052] In one example, in the above-mentioned LED energy-saving desk lamp, the lampshade includes a first lampshade and a second lampshade, the first lampshade is fixedly mounted on the top of the lamp post, and the second lampshade is movably mounted on the outer surface of the first lampshade.

[0053] In a specific implementation, the first lampshade can be made of a transparent concave lens. When the light passes through the first lampshade, due to the scattering effect of the concave lens on the light, the light will diverge to expand the illumination range. The second lampshade is set to be an opaque material. The second lampshade covers the top of the first lampshade. Under the action of the second lampshade, the light can only irradiate below the second lampshade. A preset value for sound intensity is set. When the sound sensor detects that the sound intensity reaches the preset value, the adjustment device is started to control the second lampshade to move upward. At this time, the first lampshade is exposed, the light is scattered by the concave lens, and the illumination range is expanded. When the sound is lower than the preset value, the adjustment device controls the second lampshade to move downward, so that the energy-saving desk lamp returns to its original working state.

[0054] In specific implementation, the current flowing through the energy-saving desk lamp can be reduced to reduce the intensity of the light and further reduce the light penetration. At this time, the lighting range will also be reduced, which can effectively reduce the waste of electricity and improve the energy-saving effect.
