Description

L ED hidden light-emitting source type anti-glare table lamp

Technical Field

The invention relates to the technical field of L ED lamps, in particular to a L ED hidden light-emitting source type anti-glare desk lamp.

Background

There are three common types of glare: direct glare, contrast glare and reflected glare; direct glare is glare that eyes feel when looking directly at a light source, such as directly at the sun or at night when the opposite vehicle is on the car, and direct glare when reading is glare when looking directly at a lamp tube; when the light-dark ratio of two different indoor light sources (such as a main lamp on a ceiling and a desk lamp used for reading) is too large, contrast glare can be generated; the reflection glare is the secondary light reflected to the eyes after the light source projects the object, and is generally called reflection glare, which is the most common glare and has the greatest impact on comfort, and because the glare occurs at an angle where the incident angle (the incident angle of the light source projected to the reading object) is equal to the reflection angle (the reflection angle reflected to the eyes), the glare cannot be avoided under a normal reading angle. According to the research report, four office workers have four symptoms of headache, fatigue and frequent lacrimation, and 55.9% of visitors in students with high learning pressure show that the desk lamp is frequently suffered from the troubles of aching eyes, rubbing eyes, tearing and the like.

L ED desk lamp is a desk lamp using L ED (L light Emitting Diode) as light source, L ED is a solid semiconductor device which can directly convert electricity into light, L ED lighting technology used by the desk lamp is the third generation lighting technology, solid light source is a novel light source which is seen by the industry in the coming decade and has great potential to replace traditional lighting apparatus, represents the future of lighting technology, develops new solid lighting, not only is the revolution of the lighting field, but also meets the requirements of building resource-saving and environment-friendly society proposed by the current government, L ED desk lamp has the characteristics of energy saving, environmental protection and safety and reliability, but the longer the lighting time of the ED L lamp is, the faster the attenuation of fluorescent powder in the light source is, the more and more intense the illumination of blue light wave band contacted by human eyes is caused as a result, the harm is caused to human eyes, so that the eyes see L ED light source for a long time, the feeling of dizziness and even causing eye damage to the eye diseases is increased, and the probability of eye diseases is increased.

The light source of the existing ordinary L ED desk lamp is directly exposed outside, is relatively dazzling and is easy to generate glare, so people gradually change and hope to design an anti-glare ordinary L ED desk lamp, the invention patent with the prior patent application number of 200710093780.9 provides a desk lamp with an anti-glare function, the desk lamp is mainly provided with a microstructure light control assembly formed by combining a similar Fresnel microstructure and a light control structure assembly, the similar Fresnel microstructure is used for diffusing or converging light provided by the light source, and the diffusion structure is used for controlling the light projection direction, so that the aims of preventing glare and increasing the light emission uniformity are achieved.

Although the invention can solve the problem of anti-glare, the desk lamp has a complex structure, complicated steps in the production process and high production cost, and is not convenient for large-scale production.
