Problems solved by technology

However, because its design mainly uses the coating to reflect the light emitted by the LED to the front, it still cannot solve the problem of uneven light emission of LED bulbs.

Abstract

The invention discloses a manufacturing method for light guide column. The manufacturing method for light guide column comprises the steps as follows: forming the light guide column and the pedestal, the light guide column and the pedestal are integrated together; forming a lamp cup at the top end of the light guide column; forming the reflect light thin film on the cup wall of the lamp cup, the reflect light thin film is used for reflecting the light ray for increasing the range of the emergent ray and balancing the ray; forming a light outlet at the bottom of the centre end of the lamp cup, the cup wall with the light outlet has no reflect light thin film, so that the light ray can be ejected through the light outlet. According to the manufacturing method for light guide column, the lighting range of the LED module is effectively increased and the lighting uniformity of the LED module is increased.

Description

technical field [0001] The invention relates to a manufacturing method of a light guide column, in particular to a manufacturing method of a light guide column coated with a light-reflecting film and including a light outlet. Background technique [0002] In recent years, the technology of using LED devices has become more and more mature, and the brightness has also been improved day by day, which has commercial application value. Since the LED is similar to a point light source, it is easy to form a glare phenomenon, especially in the application of high-power LED, which is more likely to cause discomfort to the eyes of the user. In addition, the light emitting angle of LED is within about 120 degrees. Therefore, compared with incandescent lamps and halogen lamps, the light of LED lamps is more concentrated in the front, and the lateral illumination is extremely uneven and the irradiation range is smaller. These factors are not conducive to the application of LEDs, so the...
