Problems solved by technology

[0002] The light intensity distribution of traditional LED light sources in three-dimensional space has a certain directionality. When the LED lighting source illuminates the entire range of the room, the light with strong directivity and the light with weak directivity exist at the same time, and the probability of dazzling the observer will decrease. Can become enlarged, especially if it makes it difficult for the eyes to see objects or is dazzling and uncomfortable
Existing LED lamps generally adopt the form of absorbing light and sacrificing the LED lighting effect to achieve anti-glare, thereby reducing the efficiency of the light source

Embodiment Construction

[0034] refer to Figure 1-13 As shown, a light guide lens of the present invention includes a bar-shaped body 1 that can extend along the length direction by an upper surface 11, a first side surface 12, a second side surface 13, and a lower surface 14. The first side surface 12 It is erected, and the second side surface 13 is inclined outward relative to the first side surface 12. The lower bottom edge of the second side surface is at least lower than the first side surface, and micro-convex lenses are evenly arranged along the second side surface 13. 15. The lower surface 14 is in the shape of a circular arc and is composed of multiple successively connected small arcs. Preferably, the height of the second side surface is 2 to 3 times that of the first side surface.

[0035] The second side surface 13 is inclined outwards at an angle of 15-65 degrees relative to the first side surface 12, and an angle of 45 degrees is the best.

[0036] The upper surface 11 is arranged hor...

Abstract

The invention discloses a light guiding lens and a light emitting diode (LED) lamp. The light guiding lens and the LED lamp comprise a strip-shaped body which is composed of an upper surface, a first side surface, a second side surface and a lower surface, and the strip-shaped body can extend along the length direction. The first side surface is vertically arranged. The second side surface is outwardly and obliquely arranged relative to the first side surface. The lower bottom edge of the second side surface is at least lower than the first side surface. Micro convex lenses are evenly distributed on the second side surface. The light guiding lens and the LED lamp can avoid a dazzling effect on eyes by strong directional irradiating light rays of a lamp bead, achieves the technical effect of restraining the dazzling phenomenon, has the advantages of being good in heat dissipation effect and lighting effect and soft in light, and achieves the purpose of a good lighting effect.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a light guide lens and an LED lamp. Background technique [0002] The light intensity distribution of traditional LED light sources in three-dimensional space has a certain directionality. When the LED lighting source illuminates the entire range of the room, the light with strong directivity and the light with weak directivity exist at the same time, and the probability of dazzling the observer will decrease. Can become enlarged, especially if it makes it difficult for the eyes to see objects or feels dazzling and uncomfortable. Existing LED lamps generally adopt the form of absorbing light, sacrificing the LED lighting effect to achieve anti-glare, thereby reducing the efficiency of the light source. Therefore, how to solve the above problems is an urgent problem to be solved. Contents of the invention [0003] The invention aims to provide a light guide lens with soft light, wide irradiation...
