Precautions for the use of Taiming's COB light source
Before using our COB light source products, please read this instruction
carefully to avoid causing bad products!
1. Installation instructions and precautions:
1. Do not use the LED drive power supply that exceeds the recommended
voltage/current of our company to light up. You need to use our recommended
voltage/current or the following recommended voltage/current drive;
2. When using this product, please ensure that the positive and negative
poles of the LED drive power supply are welded to the positive and negative
poles of the LED light source respectively. Do not weld the positive and
negative poles incorrectly;
3. The power supply must be discharged when welding, please do not work with
electricity;
4. For the protection of static electricity, the assembly table (workbench)
must be equipped with an anti-static table mat and 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 with silicone encapsulation
process. Please be careful not to touch or press the light source silicone
during manual welding. When assembling the reflector and lamp housing, do not
press the light source dam glue (our COB light source dams are all Surrounding
the two pads) and the surface of the light source colloid to prevent the
internal gold wire of the LED light source from breaking due to external force,
causing some LEDs to be off (or flickering);
6. Since the high-power LED light source is a heat-generating object, heat
dissipation measures must be taken during installation and use. When assembling
LED light source products, it is necessary to
Several heat-dissipating grease (specification: solidification temperature
≥250°C, thermal conductivity ≥3.0) is applied to the bottom of the light source
in an appropriate amount and evenly, which is conducive to enhancing the heat
dissipation effect of the product during use. A good heat dissipation structure
can ensure that the product has a smaller light attenuation. The service life is
longer; the light source coated with heat-dissipating grease should not be
pressed onto the surface of the gel when installed on the lamp;
7. It is recommended to use a 1.8mm temperature-controlled soldering iron for
soldering. Using temperature controllable soldering equipment at 300℃±10℃, the
soldering time is 5-6 seconds. It is best to add a solder ball with solder paste
before soldering to reinforce the soldering to prevent false soldering and save
soldering time. Avoid the rapid expansion of silica gel due to too long welding
time and high temperature, which will cause the gold wire to break and kill the
lamp; before welding, it is best to use a welding gun to solder proper tin on
the pad, which can strengthen the welding and prevent false welding. Can save
welding time;
8. The protective film plays a protective role for the LED light source
during the manufacturing process. Please do not remove the protective film
before and after welding to prevent debris and dust from sticking to the surface
of the light source; the protective film must be removed before lighting to
prevent the light source from being lit and high temperature melting Protective
film, causing damage to the light source;
9. This product is a constant current component, please do not use constant
voltage drive; otherwise, the color and brightness will be inconsistent. And
when the ambient temperature rises, the junction temperature of the LED light
source increases to reduce the internal resistance, and the current of the LED
light source increases, which affects its lifespan and seriously causes the LED
to "burn out". Therefore, it is best to use a constant current source to supply
power to ensure the stability of the light source;
10. If the desiccant is yellow or expired, the light source should be
dehumidified at 60°±6°/24 hours before use;
11. After aging for 2H, the temperature of the light-emitting surface cannot
be higher than 120 degrees, the temperature of the negative terminal of the
substrate is lower than 80 degrees, and the temperature difference between the
substrate and the case should be within 20 degrees;
12. If there is an abnormality in the product (such as the situation that it
cannot be lighted normally), please do not use it by welding, and contact our
professional staff to solve the problem on the same day.
