Taiming Optoelectronics Technology uses imported raw materials to package the
Taiwan process, using high thermal conductivity copper bracket, pure gold wire,
high temperature resistant glue packaging, high power, small size and easy
assembly.
COB light source use precautions
Use our COB light source products, please read this instruction carefully
before use to avoid causing bad products to occur!
First, the installation instructions and precautions:
1. Do not use LED driver power supply that exceeds our recommended
voltage/current. It should be driven by our recommended voltage/current or
recommended voltage/current.
2. When using this product, please ensure that the positive and negative
poles of the LED light source are soldered to the positive and negative poles of
the LED light source respectively.
3. The power supply must be discharged during welding. Do not carry live
work;
4, static protection, assembly station (workbench) need to use anti-static
mats, and should be grounded. The soldering iron must be grounded to prevent
excessive static electricity from causing breakdown of the chip and leakage or
dead light;
5. Our company adopts the LED light source of the silicone packaging process.
When hand welding, please be careful not to touch or press the light source
silica gel. When assembling the reflector cup and the lamp housing, do not press
the light source dam glue (our COB light source dam is Surrounding the two pads)
and the surface of the light source colloid to prevent the occurrence of partial
LED non-brightness (or flickering) caused by the external gold force breaking
inside the LED light source;
6. Since the high-power LED light source is a hot object, heat dissipation
measures must be taken during installation and use. High thermal conductivity is
required when assembling LED light source products
The number of heat-dissipating silicone grease (specification: solidification
temperature ≥250°C, thermal conductivity ≥3.0) is evenly applied to the bottom
of the light source, which is beneficial to the product to enhance the heat
dissipation effect during use. The good heat dissipation structure can ensure
the light decay of the product is smaller. Longer service life; do not apply
light to the surface of the gel when installing on the luminaire;
7. It is recommended to use a soldering iron with a size of 1.8mm to control
the soldering iron. The temperature can be controlled at 300 °C ± 10 °C, and the
welding time is 5-6 seconds. It is best to add a solder ball with solder paste
before soldering to strengthen the welding to prevent the welding and save the
welding time. Avoid the rapid expansion of the silica gel due to the long
welding time and high temperature, so that the gold wire pulls the broken lamp;
before welding, it is best to weld the appropriate tin on the pad with the
welding torch, which can strengthen the welding and prevent the false welding.
Can save welding time;
8. The protective film plays a protective role on the LED light source during
the process. Do not tear off the protective film before and after soldering to
prevent debris and dust from sticking to the surface of the light source. Before
lighting, the protective film must be removed to prevent the light source from
igniting and melting at high temperature. Protective film, causing damage to the
light source;
9. This product belongs to constant current type components. Do not use
constant voltage drive; otherwise, color and brightness will be inconsistent.
When the ambient temperature rises, the junction temperature of the LED light
source increases, the internal resistance decreases, the LED light source
current rises, affecting its life, and the LED is “burned out” seriously.
Therefore, it is better to use a constant current source to ensure the light
source is stable;
10, the desiccant is yellow or expired, the light source should be
dehumidified with 60 ° ± 6 ° / 24 hours, and then used;
11. After aging 2H, the temperature of the light-emitting surface should not
be higher than 120 degrees, the temperature of the negative electrode of the
substrate should be lower than 80 degrees, and the temperature difference
between the substrate and the outer casing should be within 20 degrees;
12. If the product is found to be abnormal (if it cannot be lit normally),
please do not use it for welding, and contact our professional staff on the same
day to solve the problem.
