Light-emitting device with function of optical flame imaging

Abstract

The invention provides a light-emitting device with a function of optical flame imaging. The light-emitting device comprises a light source, a light guide post and a cover. The light guide post is provided with an incoming end and an outgoing end. The cover covers around the light guide post. Light emitted by the light source enters the light guide post from the incoming end and is guided by the light guide post to emerge out of the outgoing end; the light emerging from the light guide post is partially reflected and refracted to form an optical flame image in a light condensing area between the cover and the light guide post.

Description

technical field [0001] The present invention is a light-emitting device with optical flame imaging, especially through the guide and refraction of the light guide column, and cooperates with the partial refraction and reflection of the light by the cover to form an optical flame image between the light guide column and the cover. light emitting device. Background technique [0002] With the rise of the concept of green environmental protection, lighting fixtures used in the past, such as fluorescent lamps or incandescent bulbs, are gradually replaced by LED lamps due to their large power consumption and high heat generation characteristics. LED lamps use light-emitting diodes As a light source, compared with fluorescent lamps or incandescent bulbs used in the past, it has lower power consumption and service life, and does not have the pollution and danger of mercury vapor like fluorescent bulbs. [0003] However, the existing LED lamps are limited by the light-emitting diod...

Problems solved by technology

[0003] However, the existing LED lamps are limited by the light-emitting diode packaging and light-emitting characteristics. The disadvantage is that the light generated by the light-emitting diode can only be concentrated forward. In order to provide effective lighting, it is necessary to add a diffuser to the lampshade to achieve a uniform light output and lighting effect, or set a light guide column inside the lamp to guide the projection angle of the light, and pass through the light guide column. The change of the type guides the light to produce different refraction and reflection, so as to provide a more uniform light output and lighting effect

[0004] The LED lamps of the prior art only simply solve the problems of uniform light output and lighting, but they still cannot further provide consumers with different viewing and interesting effects in terms of the appearance and vision of the LED lamps, and the monotonous lighting performance is difficult. Create the visual effect of traditional flames, forming the purchase desire of consumers who cannot replace traditional light sources and pay attention to visual effects
