High-angle blister structure

Abstract

The invention discloses a large-angle bulb shell structure. The large-angle bulb shell structure comprises a bulb shell and an LED light source arranged below the bulb shell, wherein the bulb shell is of a shell structure with an open bottom; a light guide element is arranged in the bulb shell; the light guide element comprises a light entering surface, a light guide part and a light exiting part; the light entering surface is located at the bottom of the light guide element and faces towards the opening; the light exiting part is arranged in a manner of being corresponding to the sidewall of the bulb shell; the LED light source is arranged below the light entering surface; at least a part of light rays emitted by the LED light source enters the light guide part from the light entering surface; and the light guide part is used for guiding the light rays to the light exiting part, and then the light rays irradiate towards the bulb shell. According to the invention, because the light rays are guided by the light guide part towards the sidewall of the bulb shell, the sidewall of the bulb shell becomes a main light emitting surface, and then the bulb shell has the advantage of achieving large-angle light emitting.

Description

technical field [0001] The invention relates to an LED lighting fixture, in particular to a large-angle bulb structure. Background technique [0002] In recent years, with the continuous advancement of lighting technology, LED, as a new type of green and efficient semiconductor light source, has been applied in the field of lighting. LED light sources have the advantages of high luminous efficiency, low heat generation, power saving and long life, so their applications are becoming more and more extensive. LED lamps will gradually replace traditional lighting fixtures such as incandescent lamps and halogen lamps. The light angle of LED candle light is generally between 200 and 300 degrees, and the candle light with transparent bubble structure, in order to achieve large-angle light, usually adopts the method of adding a lens or a light distributor. However, the cost of adding lenses or light distributors is high and cannot be ignored. This has become a major problem in red...
