Embodiment 1

[0018] Such as figure 1 , figure 2 , image 3 A dot-matrix module without a reflector is shown, including a circuit board 1, on which a plastic case 2 is installed, and more than one light-emitting through-hole 3 is opened on the said plastic case 2, and the light-emitting through-hole A light source 4 is installed on the circuit board 1 inside 3 , and a pad 5 is installed on the bottom surface of the circuit board 1 .

[0019] There are 256 light-emitting through holes 3 in the plastic shell 2, and the 256 light-emitting through-holes 3 are divided into 16 rows, and each row has 16 light-emitting through-holes 3 . The distance between the centers of two adjacent light-emitting through holes 3 is 0.9 cm, and the diameter of the light-emitting through holes 3 is 0.7 cm.

[0020] A protective film 6 is sprayed on the plastic shell 2 , and a protective film 6 is also sprayed on the inside of the light emitting through hole 3 above the light source 4 . The setting of the prot...

Abstract

The invention discloses a lattice module without a reflection cover. The module comprises a circuit board, a rubber shell is installed on the circuit board, one or more light-emitting through holes are formed in the rubber shell, light sources are installed in the parts, inside the light-emitting through holes, of the circuit board, and a bonding pad is installed on the bottom face of the circuit board. According to the lattice module without the reflection cover, through the arrangement of being without the reflection cover, production cost is reduced, through the precision arrangement of the light-emitting through holes, the light-emitting resolution ratio is greatly raised, and the rubber shell and the circuit board are directly installed in a matched mode, so that the maintenance is facilitated.

Description

technical field [0001] The invention relates to a dot matrix module without a reflection cover. Background technique [0002] The nixie tube includes a reflector cover. The reflector cover of the nixie tube currently used in the market is equipped with a circuit board. The processing cost of the nixie tube with the reflective cover is high, and the luminous resolution is affected by the luminous through hole provided on the reflective cover, and it is not easy to maintain. Contents of the invention [0003] The purpose of the present invention is to provide a dot matrix module without a reflective cover, which reduces the production cost without the reflective cover, and the precise setting of the luminous through hole greatly improves the luminous resolution, and the plastic shell and the circuit board are directly matched and installed Easy maintenance. [0004] In order to achieve the above object, technical scheme of the present invention is: [0005] A dot-matrix m...
