Large-angle light distribution illumination module and ceiling lamp with the same

Abstract

The invention provides a large-angle light distribution illumination module which comprises two LED lamp tubes. Each LED lamp tube comprises a tube body, an LED light source plate arranged in the tube body and an LED light source. A microstructure is arranged on the inner wall of each tube body. The microstructures are arranged at light outlets of the LED light sources, so that out-going light of the light sources is converged through the microstructures. The two LED lamp tubes are parallel and are arranged in a co-plane mode, so that the included angle alpha between two surfaces of the LED light sources arranged on the two LED light source plates in the two LED lamp tubes is between 0 degree and 180 degrees. According to the technical scheme, the LED lamp tubes can be directly used for replacing a fluorescent tube, bright-dark fringes are removed when bat wing light distribution is generated, and brightness is even.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to a large-angle light distribution lighting module and a ceiling lamp with the lighting module. Background technique [0002] Most of the ceiling lamps currently on the market still use traditional fluorescent tubes, which have low light efficiency and high energy consumption, and will cause the following problems: [0003] The light distribution of traditional fluorescent tubes is a 360-degree circle. When used in luminaires, a large part of the light hits the chassis of the luminaire, and is reflected by the chassis and finally emitted from the mask, resulting in light loss. Therefore, the efficiency of luminaires using traditional fluorescent tubes is not high. . [0004] Therefore, from the perspective of energy saving, LED light tubes are usually used instead of fluorescent light tubes. But again, the direct use of LED light tubes instead also produces the following problems...

AI Technical Summary

Problems solved by technology

[0002] Most of the ceiling lamps currently on the market still use traditional fluorescent tubes, which have low light efficiency and high energy consumption, and will cause the following problems:

[0005] Most LED lamps do not control the light, so in lamps such as ceiling lamps, refer to figure 1 , will form ugly light and dark stripes on the lampshade, affecting the appearance of the product, which becomes a factor restricting the use of LED lamps in ceiling lamps
