Description

Self-adaptive safe eye-protection desk lamp

Technical Field

The utility model relates to an indoor lighting equipment field.

Background

The lighting lamp is one of essential light sources in life of people, novel light sources such as fluorescent lamps and LED lamps are more widely applied under the trends of environmental protection, energy conservation, emission reduction and continuous development all over the world, but the novel energy-saving light sources have more blue light components. The blue light wavelength is 380-500 nanometers, is visible light with the highest energy, can directly penetrate the crystalline lens of the eyeball to directly reach the macular area of the eye, and causes macular degeneration, and the injury is often irreversible! According to data of sampling survey at the end of 2018, the myopia rate of children at 6 years in a kindergarten in China is 14.8%, the myopia rate of pupils is 31.4%, the myopia rate of junior and middle school students is 64.8%, the myopia rate of high school students is 76.2%, and the ultrahigh myopia rate directly threatens the sustainable development of the economic society.

The existing LED table lamp claims to have an eye protection function, but the blue light is inevitable in fact. The light emitted by the traditional incandescent bulb is better for reading, but because the energy efficiency ratio is low, the problem of energy waste does exist even if the traditional incandescent bulb is used for a long time in a large amount, and the traditional incandescent bulb does not accord with the national energy-saving policy.

Therefore, the existing desk lamp needs to be improved to achieve both health and energy saving.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1, the adaptive safety eye-protection desk lamp of the present embodiment includes: a base 1, a support 2 and a cap member 3. One end of the supporting piece 2 is connected with the base 1, the other end of the supporting piece 2 is connected with the lamp cap piece 3, and the lamp cap piece 3 can be adjusted in any posture under the action of supporting force provided by the supporting piece 2.

As shown in fig. 1, the base member 3 includes an LED lamp group and an incandescent lamp group. The LED lamp group is composed of a plurality of LED lamp beads 30, and in this embodiment, the LED lamp beads enclose a closed ring shape in a track shape, which is called as an LED lamp ring 31. And 2 incandescent lamp bulbs 32 are arranged in the space surrounded by the LED lamp ring 31, and the 2 incandescent lamp bulbs 32 form an incandescent lamp group. Thus, the LED lamp group and the incandescent lamp group constitute a layout in which the former surrounds the latter. Moreover, each incandescent lamp bulb 32 is positioned at the inner side of the arc segment of the LED lamp ring 31, so a certain distance is left between 2 incandescent lamp bulbs 32, thereby not only improving the irradiation range, but also being beneficial to the heat dissipation of the bulbs. In this embodiment, an LED lamp set optical module (not shown) is disposed corresponding to the LED lamp set, and an incandescent lamp set optical module (not shown) is disposed corresponding to the incandescent lamp set, and the two optical modules are used for correspondingly improving the uniformity of light of the LED lamp set and the incandescent lamp set and controlling the direction of illumination.

In this embodiment, the power converter is embedded in the base 1, and the power converter is connected to the mains supply through a cable. As shown in fig. 2, the output terminal of the power converter is a 24V dc output terminal, and the dc output terminal is connected to the light source control module for operating the LED lamp set or the incandescent lamp set.

A light source control module is arranged in the base 1, and a human body induction device is arranged on the base. As shown in fig. 2, the output terminal of the power converter is electrically connected to the first input terminal of the light source control module, and the signal output terminal of the human body sensor is connected to the second input terminal of the light source control module. In this embodiment, the infrared human body probe 11 is selected as the human body sensing device, once the infrared human body probe 11 detects the human body characteristics, a high level signal is continuously transmitted to the second input end of the light source control module through the output end of the infrared human body probe, and the duration is determined by the parameters of the delay circuit of the infrared human body probe. In the process of time-delay countdown, if the human body characteristics are detected again, the time-delay countdown is restarted. As long as the second input end of the light source control module is always at a high level, the light source control module always keeps controlling power supply to the incandescent lamp group to enable the incandescent lamp group to be turned on, and keeps turning off the LED lamp group. If the person walks away or is in a position which cannot be detected by the infrared human body probe, after the delay countdown is finished, the second input end of the light source control module becomes a low level, the light source control module controls to cut off power supply to the incandescent lamp group and controls to supply power to the LED lamp group, and therefore automatic switching between the LED lamp group and the incandescent lamp group is completed.

It should be noted that the human body sensing device is not limited to be disposed on the base 1, but should be disposed on a portion of the lamp approximately facing the human body, so as to improve the accuracy of human body detection, and such a portion may also be a support member or a lamp head member.

The support member 2 of the present embodiment is bendable so that it is convenient for a person to adjust the light to a comfortable illumination angle.

The desk lamp of the embodiment can also be provided with a charging control module and a rechargeable battery in the base. The charging control module is communicated with the output end of the power converter. In case of mains supply failure, the rechargeable battery can be discharged, so that the lamp can be used for emergency lighting. In addition, a USB interface can be arranged on the shell of the base, the USB interface is communicated with the rechargeable battery, and the rechargeable battery can supply power for the mobile equipment with the USB charging function.
