IR LED Excellent Corrosion Resistance

Infrared LED lamp bead is our lighting tool will encounter a component, that is related to its knowledge is that we want to give you the following, to explain the infrared LED lamp beads are made of what material.

1. Material ADC12 (Japan's aluminum alloy, also known as No. 12th aluminum, AL-SI-CU alloy, is a die-casting aluminum alloy, suitable for lid, cylinder type, etc.).

2. Antirust aluminum: Mainly Al-mn and MG series alloys. Because of its aging effect is not obvious, it is not appropriate to strengthen heat treatment, but can be hardened through processing to improve strength and hardness. This kind of alloy main performance characteristic is has the good corrosion resistance, IR LED therefore is called the rust-proof aluminum.

3. PA: Polyamide has high mechanical strength, high softening point, heat resistance, low friction coefficient, abrasion resistance, self-lubricating, shock absorption and silencing, oil resistance, weak acid, alkali and general solvents, good electrical insulation, self quenching, non-toxic, IR LED odorless, good weather resistance, poor dyeing.

4. Q235: A carbon structural steel that represents a yield point (σs) for $number MPa. As the thickness of the material increases, the yield value decreases. Due to moderate carbon content, comprehensive performance is good, strength, plasticity and welding properties have been better fit, IR LED the most widely used.

5. LED: Its basic structure is an electroluminescent semiconductor material chip, with silver or white glue solidified to the bracket, and then use silver or gold wire to connect chips and circuit boards, and then four weeks with epoxy resin seal, play the role of protecting the inner core line, the final installation of the shell, so the LED lamp seismic performance is good.

1. Straight-Plug Small power specifications are: Straw hat/helmet, IR LED round head, concave, oval, square type (2*3*4) bullet, flat head, (3/5/flat/bread type) piranhas and so on.

2. SMD patches are generally divided into (3020/3528/5050 these are positive light-emitting)/1016/1024, etc. these are side light sources.

3. High-power LED can not be categorized to the patch series, IR LED their power and current use are not the same, and photoelectric parameters vary greatly. Single high-power LED light source without cooling base (generally six-corner aluminum block), its appearance and ordinary patch is not too big gap, high-power led light source is round, the package is basically the same as SMD patches, but with SMD patches in the use of conditions/environment/effect, there are essential differences.

1. Voltage: Infrared LED lamp beads use low-voltage power supply, IR LED supply voltage between 2-4v, according to different products, so drive it is a higher than the high-voltage power supply, a more secure power supply, especially suitable for public places;

2. Current: Working current in 0-15ma, brightness increases with current.

3. Effectiveness: Energy consumption is less than the same light efficiency of the incandescent lamp 80%.

4. Applicability: Very small, each unit LED small piece is 3-5mm square, so can be prepared into a variety of infrared LED lamp beads infrared LED lamp shape of the device, IR LED and suitable for variable environment.

6. Response time: The response time of the incandescent lamp is millisecond, and the response time of the LED lamp is nanosecond.

7. Environmental pollution: No harmful metal mercury.

8. Color: Changing the current can change color, light-emitting diode conveniently through the chemical modification method, adjust the material's energy band structure and band gap, realize the red yellow green Blue orange multi-color luminescence. such as small current when the red LED, as the current increases, you can turn into orange, yellow, and finally green.
