4 UV damage on the human body

UVA-direct access to the skin dermal layer, destruction of elastic fibers, I
Their skin tanning;

UVB-erythema role of the human body, can promote the body of minerals on behalf of
Xie and the formation of vitamin D, but the long-term or excessive exposure of skin
Tan, and causing swelling and peeling;

UVC-body injury, short time exposure to burns wholesale
The long-term or high-intensity radiation can also cause skin cancer;
Of UVD-ultraviolet, the shorter the wavelength, the greater the harm on the human skin.

Note: 10W in a market within the meaning of "10W high-power white LED is not its power, but vulgar refers to the actual power to see the top of the table.
If the maximum current value illuminate the LED, be sure to enhance heat dissipation measures, or to accelerate the light fades.

Instructions for safe use of high-power LED products
High-power LED products and devices in the application process, thermal, electrostatic protection, welding has a great impact on its characteristics, need to attract customers attach great importance to the application side

First, the heat:
Semiconductor light-emitting diode chip technology limitations of LED photoelectric conversion efficiency remains to be improved, especially in high-power LED, because of the higher power, about 60 percent more electrical energy into heat release (along with the development of semiconductor technology photoelectric conversion efficiency will be gradually increased), which requires the end-customer to do when the application of high-power LED products heat work to ensure the normal work of the high-power LED products.

1. The heat sink requirements.
The shape and material: If the finished seal less demanding, with the outside air environment a direct convection, we recommend using aluminum or copper heat sink fins.

2. Effective cooling surface area:
1W high power LED white (other colors are basically the same) Division I recommended to the sum of the effective cooling surface area of the heat sink 50-60 square centimeters. 3W products, recommended the sum of the effective cooling surface area of the heat sink than 150 square centimeters, as the case of higher power and test results to increase as much as possible to ensure that the heat sink temperature does not exceed 60 .

3. Connection method:

Please ensure that the two contact surfaces smooth connection of high power LED substrate and heat sink, good contact, to enhance the degree of integration of the two contact surfaces, it is recommended that the surface coating layer of thermal grease in the bottom of the LED substrate or heat sink (thermal grease thermal conductivity the 3.0W/mk), thermal grease evenly coated, amount, and then screw press fit fixation

Second, the electrostatic protection.
LEDs are semiconductor devices, are more sensitive to static electricity to prevent static electricity and eliminate static electricity work to do, especially for white, green, blue, purple LED.

1. Generation of static electricity:

friction: in everyday life, any two objects of different materials contact after separation, you can generate static electricity, while the most common way to generate static electricity, friction power. The better the insulation of the material, the more likely friction call. In addition, any two different substances, objects in contact after separation, can also generate static electricity.
induction: a conductive material, due to the electron energy in the surface of the free flow, if placed in an electric field, due to same-sex repulsion, opposites attract, the positive and negative ions will be transferred on its surface will produce charge .
conduction: for electronic contact with the electrically charged objects in its surface free flow of conductive material, the charge transfer.

2.The hazards of static LED:

heat generated due to the instantaneous electric field or current, the LED local injury, the performance of the rapid increase in leakage current, and still work, but
The decrease in brightness, life impaired.
electric field or current destruction of the insulation layer of the LED, the device does not work (completely destroyed), dead lights.

3 ESD and the elimination of measures:

All employees have direct contact with the LED for the entire process (production, testing, packaging, etc.) do to prevent and eliminate static electricity measures, mainly
A workshop laying anti-static floor and good grounding.
2, the table to prevent static table, the production machine well grounded.
3, the operator to wear anti-static clothing, with a wrist strap, gloves or foot ring.
4, the application of ion fan.
, Welding, soldering iron to do the grounding.
6, packaging, anti-static material.
