Problems solved by technology

However, the warm white light emitted by the dimmable color LED desk lamp does not reduce the blue light, and still cannot reduce the harm of blue light to human eyes.
[0007] The eye protection schemes of desk lamps in the prior art do not take into account the harm of blue light to human eyes, and have not made significant improvements to the light source part, so the harm of blue light to human eyes cannot be avoided

Embodiment 1

[0028] Such as figure 1 As shown, it is an anti-blue desk lamp, which includes a base 8, a connecting unit 9, a lampshade 2 with an opening 1, and an LED light source 3 inside the lampshade 2. The lampshade 2 is installed on the base 8 through the connecting unit 9, namely One end of the connection unit 9 is installed on the base 8, and the other end of the connection unit 9 is equipped with a lampshade 2, the lampshade 2 is concave and hollow, the inner surface 6 of the lampshade 2 is a reflective curved surface, and the inner surface 6 of the lampshade 2 There is a blue light absorbing layer on it.

[0029] The LED light source 3 includes a blue LED chip and a yellow phosphor coated on the blue LED chip; the blue light-absorbing substance in the blue light absorbing layer has a reflectivity of less than 30% for visible light beams in the range of 440nm to 480nm, and has a visible light greater than 600nm. The reflectivity is higher than 90%. The substance that absorbs blue...

Embodiment 2

[0034] Such as image 3 As shown, it is another anti-blue light table lamp, which is different from Embodiment 1 in that the LED light source 3 is installed on the lamp panel 7, and the others are the same as Embodiment 1.

[0035] The LED light source 3 is LED luminous particles and is located on one side of the lamp board 7 , and the side of the lamp board 7 with the LED luminous particles faces away from the opening 1 of the lampshade 2 . The lamp board 7 is strip-shaped and erected inside the lampshade 2, the lamp board 7 is Y-shaped or cross-shaped, image 3 The middle is Y-shaped.

[0036] The anti-blue light desk lamp of the present invention, the light beam emitted by the LED light source 3 is first irradiated on the inner surface 6 of the lampshade 2, and after being reflected by the inner surface 6 of the lampshade 2, it is emitted to the outside of the lamp. At the same time, it takes into account the reduction of the blocking of the outgoing light and improves th...

Embodiment 3

[0039] Such as Figure 4 As shown, it is another anti-blue light table lamp, which is different from Embodiment 1 in that the LED light source 3 is installed on the lamp panel 7, and the others are the same as Embodiment 1.

[0040] The LED light source 3 is LED luminous particles and is located on one side of the lamp board 7 , and the side of the lamp board 7 with the LED luminous particles faces away from the opening 1 of the lampshade 2 . The lamp plate 7 is circular and fixed closely on the inner surface 6 of the lampshade 2 .

[0041] In the anti-blue light table lamp of the present invention, the light beam emitted by the LED light source 3 is first irradiated on the inner surface 6 of the lampshade 2, and after being reflected by the inner surface 6 of the lampshade 2, it is emitted to the outside of the lamp. and minimize the blocking of the outgoing light, the blue light absorbing layer on the inner surface 6 of the lampshade 2 absorbs the blue light component in th...

Abstract

The invention discloses a blue light prevention desk lamp. The blue light prevention desk lamp comprises a pedestal, a connecting element, a lamp shade and an LED light source, wherein the lamp shade with an opening is mounted on the pedestal through the connecting element; the LED light source is arranged in the lamp shade; and a blue light absorbing layer is arranged on the inner surface of the lamp shade. According to the blue light prevention desk lamp disclosed by the invention, since the blue light absorbing layer, which can filter the beam emitted by the LED light source to remove blue light and reduce outgoing blue light and can absorb blue light in the beam emitted by the LED light source, is arranged on the inner surface of the lamp shade, the blue light which is emitted outwards from the whole desk lamp, is greatly reduced, so that the desk lamp is beneficial for preventing human eyes from being hurt by blue light and plays a role of protecting the eyes. And meanwhile the desk lamp has the advantages of simple structure, energy saving and low cost, is beneficial for market popularization and application, and has a wide application prospect.

Description

technical field [0001] The invention relates to the field of desk lamps, in particular to an anti-blue light desk lamp with reduced blue light output. Background technique [0002] The eye protection table lamps currently on the market generally focus on the following aspects to achieve eye protection effects: [0003] 1. Eliminate stroboscopic lights; 2. Avoid direct glare on the eyes; 3. Eliminate shadows caused by hands and heads; 4. Correct sitting posture through sensor alarms; 5. Provide background lighting to create hyperopia conditions. The solutions adopted in the above-mentioned prior art can relieve eye fatigue to a certain extent and achieve eye protection effect. [0004] However, the World Health Organization (WHO) announced that from 2006 to 2008, more than 30,000 people around the world were blinded by blue light radiation every year. According to data from the Ophthalmology Branch of the Chinese Medical Association, among the 420 million Internet users in ...
