a lamp

Abstract

The invention discloses a lamp. The lamp comprises a shell, a light guide column, a convex lens and a light-emitting piece. The light guide column, the convex lens and the light-emitting piece are installed in the shell. The light guide column comprises a light incident end and a light emergent end, the light-emitting piece is arranged at the light incident end, the convex lens is arranged a the light emergent end, the convex face of the convex lens right faces the light-emitting piece, and the focal distance of the convex lens is equal to the distance between the top of the shell to the convex lens. Compared with the prior art, the lamp differs in that the area of the accent lighting region of the tip end of the shell of the lamp is increased, so that the dark and shadow region is sufficiently and completely covered; the problem, which exists for a long time and people feel dissatisfied with, of the dark and shadow region at the tip end of a lamp bulb is effectively solved, so that light in the lamp bulb is evener, the lighting effect and the use aesthetic feeling of the lamp are obviously improved, and the lighting quality of lamps is improved by a qualitative leap. Thus, the lamp has great popularization significance.

Description

Technical field [0001] The invention relates to a lamp, belonging to the technical field of lighting. Background technique [0002] In recent years, driven by the national policy of energy conservation and environmental protection, LED lamps have gradually replaced traditional lighting fixtures with their advantages of high efficiency, energy saving, long life, safety and environmental protection, and firmly occupy most of the domestic lighting market. [0003] Although the technology of LED lights is becoming more and more mature, due to the strong directivity of the LED light source, the light is often concentrated in the front, which makes the lateral illumination extremely uneven. The directional light also makes the illumination range very small, which affects the LED luminaire to a certain extent. Promotion. In order to solve the above-mentioned problems, people invented a light guide rod to guide the light to be emitted in a specific direction, thereby improving the phenome...

Problems solved by technology

For example, the Chinese invention patent CN102411162A discloses a light guide column for uniformly emitting light and the LED lamp using the light guide column, and a light guide column disclosed in CN102455457B. Both the light guide column is reasonably arranged in the LED lamp to change the exit angle of the light and route, so as to produce a uniform lighting effect, but in the actual use process, it is found that the LED lamp with the light guide column has brought new problems. Almost all LED bulbs with pointed tails and tailed tails, It is still a milky white bulb, and there are obvious shadows and dark areas at the tip of the bulb, while the existing LED lights only use the role of the light guide to guide the light to a certain height and then diffuse downward evenly to make the light evenly emitted and increase the brightness. Large light-emitting surface, but did not realize the problem of local dark areas caused by the shape of the sharp tail and the tail LED lights, especially when the bulb is milky white, even if someone finds the crux of the problem, However, no effective solution has been proposed so far, making it a long-standing technical problem in the history of LED lamp development, which reduces the quality of lighting in people's daily life, seriously affects people's use of aesthetics, and hinders the improvement of its own quality. and development, limiting the further promotion and use of LED lights
