LED lamp

Abstract

The invention discloses an LED lamp, which comprises a lampshade and LED light source, the LED light source is arranged above the lampshade; the lampshade comprises a lampshade body made of semitransparent materials, the cover body is provided with an inner surface which faces the LED light source and is obtained through atomization treatment. The LED lamp is characterized in that the LED lamp ischaracterized in that a longitudinal section of the inner surface of the cover body comprises a first area located in the middle; wherein a central point is arranged on the longitudinal section of theinner surface, the first area takes the central point as a symmetric center, an included angle between the LED light source on the same longitudinal section and the two ends of the first area is 50+ / -5 degrees, and the atomization degree of the first area is greater than that of other areas on the longitudinal section of the inner surface. By maximizing the atomization degree of the central area,the original local strong light is distributed more uniformly, the UGR value is reduced, and the light quality is improved.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED lamp. Background technique [0002] As a semiconductor device that can convert electrical energy into light energy, LED is widely used in various lighting fixtures due to its advantages of high efficiency, low energy consumption and long life. These lamps have become indispensable in people's life and work. Lighting appliances. However, since LED itself is a Lambertian light source, its luminous intensity is mostly lower on both sides and higher at the center, so LED generally cannot be directly applied to the lighting field. [0003] For example, in engineering, in order to meet the illumination requirements of various occasions, it is generally necessary to install a large number of lamps, which not only increases the workload of installation, the number of lamps is large, the power increases, and the power consumption is increased, resulting in unnecessary economic losses.

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned lampshade can diffuse the light emitted by the light source to a certain extent, the inner surface of the lampshade is not optically treated or only uniformly processed, resulting in a light distribution effect such as Figure 5 As shown, the light intensity in the middle is too large, the light intensity on both sides is too small, and the lighting angle is small; in addition, the UGR value is also large (glare), see Table 1
