Abstract

The invention discloses a method for manufacturing a lens on an LED device. The manufacturing method includes the following steps: a stand which includes a plurality of LED modules is provided; a module separating sheet which consists of a hollow area is placed on the stand and the hollow area ensures that the LED modules are exposed; a lens module particle device and the stand are combined, wherein, the lens module particle device comprises a plurality of lens module particles each of which even comprises two through holes and corresponds to each LED module on the stand; a liquid gum is injected by making use of one through hole of each lens module particle, followed by drying, solidifying and forming. The invention also provides a module particle device for making the lens on the LED device, which comprises a basic plate and a plurality of lens module particles installed on the basic plate and each lens module particle consists of two through holes used for injecting with the liquid gum. By adopting the invention, the steps of the process for forming the lens can be simplified and the time spent in the whole process can also be shortened; in addition, the cost can also be reduced due to the reusage of the lens module particle device.

Description

technical field [0001] The invention relates to a method for manufacturing a lens on an LED device, in particular to a method and a device for manufacturing a glue-injected lens by using a lens mold device. Background technique [0002] Light Emitting Diode (LED) has gradually replaced traditional lighting fixtures such as incandescent bulbs and halogen lamps due to its fast response, small size, low power consumption, low heat, and long service life. Therefore, from the beginning, LED was used as the status indicator of electronic devices, developed and applied to become the backlight of liquid crystal display, and then expanded to electronic lighting and even lighting in projectors. The application of LED is still continuing with the advancement of technology. in the extension. [0003] In the LED packaging process, in order to enhance the light-gathering effect, a lens (LENS) will be designed on the LED module. In the existing lens manufacturing method, a lens is covere...
