LED can save a lot of electricity for the country and users, and save a lot of labor for contractors. The development of LED application technology has added new vitality to the fiercely competitive advertising industry. Its different luminous patterns and applications in the production of advertising products. LEDs of different specifications have different luminous angles and brightness. So, how to choose the appropriate LED for different products, so that they can not only play a great role, but also greatly reduce costs? The application and usage precautions of LED luminous characters. Stereoscopic luminous characters mainly have the following requirements for light sources:

1. LED has the advantages of low power consumption, high brightness, vibration resistance, high reliability, long service life, no pollution, and bright colors, making it a true green lighting. The service life reaches 100000 hours.

2. The standard packaging of the light source board is 5 in a string, and the red light source board can be connected in 6 parallel strings (30 pieces). If there are more than 30 pieces, a separate circuit should be established; More than 50 light source boards of other colors should be connected in a separate circuit. The power supply should be connected to the switch power supply, and the distance between the power supply and the light source should be as small as possible.

3. LED can emit red, yellow, blue, green, white, orange, amber, blue-green dual color, red green dual color, yellow green, pure green, emerald green, etc. It can be turned into red, yellow, blue, green, white, blue, purple through CNC.

4. There are two types of LED light source modules packaged in metal shells: ZLS-PMB and ZLS-PMBC. A: The ZLS-PMB type light source board achieves side illumination and is suitable for installation on the side wall of the luminous character, illuminating the light surface uniformly through reflection. Easy installation, requires reflective material to be applied to the inner wall of the characters. Generally 3cm high from the light box, and the box height is generally required to be 7cm or higher. B: ZLS-PMBC type light source board, which can achieve front lighting, is suitable for installation at the bottom of the luminous text, directly illuminating the light surface. Require a slot width of 4cm or more and a box height of 4cm or more. The contact area between the light source board and the light box should have good heat dissipation.

5. The center distance between each light source board is generally 10cm.

6. When the slot width is less than or equal to 10, when using the ZLS-PMBC type light source board, it is generally possible to install only one side to ensure sufficient brightness; When the width is between 10-20cm, light source boards should be installed on both sides and arranged in a staggered manner as much as possible; If the width of the slot is greater than 20cm, a ZLS-PMBC type light source board needs to be installed at a spacing of about 10cm in the middle of the bottom of the slot.

7. The standard packaging of the light source board is 5 in a string, and the red light source board can be connected in 6 parallel strings (30 pieces). If there are more than 30 pieces, a separate circuit should be established; More than 50 light source boards of other colors should be connected in a separate circuit. The power supply should be connected to the switch power supply, and the distance between the power supply and the light source should be as small as possible.
