Full light distribution type LED lamp

Abstract

The invention relates to a full light distribution type LED lamp. The full light distribution type LED lamp comprises a top cap, a bulb shell, a light source component, a driving circuit, a radiating fin and a lamp holder component, wherein the top cap, the bulb shell and the lamp holder component are connected to form a lamp body, and the light source component and the driving circuit are arranged in the lamp body. The full light distribution type LED lamp further comprises a central ring arranged in the lamp body. The lamp body is separated into an upper illuminating chamber and a lower illuminating chamber by the central ring. The light source component comprises an upper light source plate and a lower light source plate which are arranged on the central ring, disposed in the upper illuminating chamber and the lower illuminating chamber respectively and connected with the driving circuit. Compared with the prior art, the full light distribution type LED lamp has a large mounting space for the driving circuit and capable of realizing large-angle illumination of standard light sources.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a full light distribution LED lamp. Background technique [0002] At present, lighting products using LEDs as light sources have been widely used, and LED lighting products are mostly used for accent lighting due to their unidirectional light emitting characteristics. [0003] Common LED products generally add a light mixing bulb larger than a hemisphere in front of the LED light source to achieve a quasi-full light distribution lighting effect. This kind of method brings two problems: 1. A bulb larger than a hemisphere can only achieve large-angle lighting with an angle greater than 180°, which cannot meet the requirements of full light distribution products; 2. Under the standard light source size requirements, the space of the bulb is too large. The large LED drive part has insufficient space, which brings certain difficulties to the design of the electronic circuit product of the drive part in...

Problems solved by technology

This kind of method brings two problems: 1. A bulb larger than a hemisphere can only achieve large-angle lighting with an angle greater than 180°, which cannot meet the requirements of full light distribution products; 2. Under the standard light source size requirements, the space of the bulb is too large. The large size leads to insufficient space for the LED drive part, which brings certain difficulties to the design of the electronic circuit product of the drive part in the product.

At present, there are also methods such as reflection to realize full light distribution of LED products, but the reduction of optical efficiency caused by reflection makes the overall performance of the product unable to reach the ideal state.
