Embodiment Construction

[0021] combined with Figures 1 to 4 , the technical solution of the present invention is described as follows:

[0022] Such as figure 1 As shown, the light guide includes a lens 11 , the lower surface of the lens 11 is a light-gathering curved surface, and a light-transmitting polygonal pyramid 12 is provided on the upper surface. The lens 11 and the polygonal pyramid 12 are integrally formed. Each side of the polygonal pyramid 12 is sunken inwards to form four light-emitting surfaces 121 . After the incident light is converged by the light-gathering curved surface of the lens 11 , it is emitted from each light-emitting surface 121 to form a multi-angle light output effect.

[0023] Such as figure 2 As shown, as an improved solution, the light-condensing curved surface of the lens 11 is additionally provided with three accommodating cavities 111 for accommodating larger volume lamp beads. The accommodating cavity 111 is recessed toward the inside of the lens 11 to provi...

Abstract

The invention provides a light guide piece, which can realize the multi-angle divergence output of incident light. The light guide piece is characterized by comprising a lens, wherein the lower surface of the lens is a condensation curved surface; the upper surface of the lens is provided with a nonopaque multi-edge pyramid; and the lens is integrally formed with the multi-edge pyramid. Meanwhile, the invention also provides an LED (Light Emitting Diode) candle lamp bulb applying the light guide piece, wherein the LED candle lamp bulb applying the light guide piece comprises a lamp cup, a transparent lamp cover and a lamp base; the transparent lamp cover and the lamp base are correspondingly installed on two ends of the lamp cup; an LED light source and a driving power source are installed in the lamp cup; the input end of the driving power source is electrically connected with the lamp base; and the output end of the driving power source is electrically connected with the LED light source. The LED candle lamp bulb applying the light guide piece is characterized in that the light guide piece is arranged in the projection direction of the LED light source in the transparent lamp cover; and the lower surface of the light guide piece is the condensation curved surface and corresponds to the LED light source. With the adoption of the LED candle lamp bulb provided by the invention, the light output has a multidirectional or omni-directional light output characteristic, so that the light output demand in the application fields of crystal chandeliers and the like is met.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a light guide and an LED candle bulb using the light guide Background technique [0002] Traditional candle light bulbs are widely used in lamps such as crystal chandeliers, and its all-round light output is refracted by crystal plates on the crystal chandeliers to produce gorgeous visual effects. With the development of technology and the trend of energy saving and environmental protection, LED technology has been fully extended to the field of lighting, providing consumers with lighting with higher quality and lower energy consumption. However, due to the strong directionality of the LED light output, it is difficult to realize the omnidirectional output of light when it is applied on the crystal chandelier, so that the visual effect of the traditional candle bulb cannot be achieved. The applicant made in-depth research on this, and realized the multi-directional and even omni-directio...
