LED secondary packaging technology and production process

  LED outdoor lighting in the night has become the mainstream of lighting products, replacing most of the traditional light sources. Designers in the landscape lighting design, has a greater creative space, so that design works are more artistic and shocking. Secondary packaged LEDs are the source of inspiration for landscape lighting designers.

 

The waterproof problem of LED lighting products has always been the biggest and fatal problem during use. The service life of LED lamps is largely constrained by the waterproof problem. Successfully solving the waterproof problem of LED lamps can ensure the life and stability of LED lamps.

Secondary package LED: After the first packaged LED and its drive or control circuit are soldered in the electronic circuit, they are sealed in the polymer package, achieving waterproof, dustproof and protective functions. Its degree of protection is up to IP68, which can be used in underwater and underground environments. Flame-retardant rating up to FV-0 level, oxygen index ≥ 28% of the highest fire-retardant rating, so that the secondary packaging LED lamps to self-extinguishing from the fire, superior safety performance. The use of UV-resistant packaging materials, so that the secondary package LED in outdoor use for 10 years does not crack on their own. The popular ultra-thin and transparent design is suitable for more occasions. After installation, the effect on the building during the daytime is very small. If the installation is reasonable, it can even be used as a decoration during the day to give the building an artistic effect. The secondary encapsulated LED has the advantage that the traditional LED luminaire products do not have, so that the lighting designer can design the cloth lamp in the underwater, underground, or any part of the building in the design of the landscape lighting, so that the imagination of the designer can be fully exerted. The design inspiration was interpreted, and generous landscape lighting works were realized.

Secondary packaging LED production process can bring the following advantages to LED products:

(1) Consistency of product quality: The secondary packaging process adopts a numerically-controlled assembly line equipment to solve the problems of poor product quality consistency and short product life caused by the previous manual rinsing with water-repellent treatment, and modern production. The equipment ensures the consistency of the quality of the lamps while increasing the production volume.

(2) Luminaire products have high water resistance: after being inspected by Shanghai Quality Supervision, Inspection and Technology Research Institute, National Electric Light Source Quality Inspection Center, and National Luminaire Quality Supervision and Inspection Center, the secondary encapsulated LED light source system has IP68 (the highest level of protection). , underwater light level).

(3) The high stability of the lamps and lanterns: Solve the problem of lamp damage and project quality caused by water in the process of outdoor use of LED lamps, which ensures the stable operation of LED large-scale projects.

The secondary packaged LED can be mainly used in the following aspects:

(1) Applied to squares and underground parks

Because the IP68 with the highest protection level of the secondary encapsulated LED can be used in harsh environments such as underground and underwater, it is widely used in landscape lamps such as squares, parks, and river courses. Such as Wuhan Jiangtan Park Glass Plaza underground landscape and display lighting, Hangzhou Xicheng Plaza underground light, Ordos lawn modeling lighting, Zhuji Puyang river lighting. Lighting designers in the design of squares, parks, rivers and other places of lighting, you can use the secondary packaging of the LED characteristics, change the limitations of traditional landscape lighting design, create a better landscape lighting works.

(2) Applied to bridge lighting

Due to the ultra-thin shape of the secondary packaged LED spot light source, transparent materials, small size, light weight, and flexible cable connection, when used on a bridge, it will not be compared with traditional LED digital light sources and traditional LED spot light sources. Destroying the daytime effect of bridges is ideal for environments where it is difficult to install and maintain such as bridges. Such as: Qingdao Danshan Bridge, Shaoxing Changyi Bridge, Nantong Yee Bridge.

(3) Applied to the outline of the building body and facade curtain wall

In the past, curtain wall lighting was a difficult-to-solve lamp lighting design subject. The secondary packaging of LED's was completely solved and this problem was completely solved. It is flexible in installation, waterproof, safe and energy-saving, and is the most ideal fixture for curtain wall node installation. The use of computer control, designed as an advertising display, can be used as part of an exterior landscape lighting or as an advertising display.

(4) Applied to Ferris Wheel

The secondary encapsulated LED fully-encapsulated insulation and its flame-retardant properties make it suitable for use in places with high safety requirements, such as use on Ferris wheel.

(5) Applied to indoor dark trough and decorative lighting

It is used in exhibition halls, fountains in bar interiors, dark troughs in hotels and other places.

(6) Apply to logos and signs

Outdoor signs, signs, use of LED instead of traditional neon lights, and LED waterproof issue has become a sign, the quality of the sign of a major factor, the secondary package LED completely solve the water quality problems and affect the life of the trouble, so a lot Used in the logo and signage industry. The applied products mainly include secondary encapsulated LED waterproof strips and secondary encapsulated LED spot light sources.

7) Applied to outdoor large advertising display

The use of computer control systems and secondary packaging of LED spot light sources to produce high-precision large-scale advertising display screens is increasingly recognized by advertising companies and advertising clients for their high cost performance. The display screen can use CF cards to play advertisements for video or text content, and can also be connected to a computer for real-time transmission and playback of various video programs.

The secondary packaged LED can be used directly as a light fixture, or it can be widely used as an internal light source for special LED lamps, such as landscape sculpture light source, art modeling light source, bridge art light source, etc., making special manufacturing LED lamps in the process of developing the lamp housing Waterproof protection requirements are minimized, and the stability of the special-manufactured lamps is also guaranteed. With the advent of secondary packaging of LEDs, LED has become an all-weather, all-round lighting product.
