Color temperature is the most general indicator of the spectral quality of a light source. Generally expressed by Tc. Color temperature is defined by absolute black body. Nowadays, LED lamps and lanterns are very common in life. There are various colors, so how much LED color temperature is good for the eyes? Next, Yijingyuan Broadcasting & TV will come to explain it for you. A report pointed out that white cold light LED and blue light LED are harmful to the eyes and should be banned. These LEDs are mainly used for decoration, and the intensity of blue light emitted by them far exceeds that of natural lighting and traditional lighting. These high-intensity blue light will cause damage to the pigment epithelium of the retina and the sensory layer of the retina at the same time, thereby accelerating retinal aging and increasing the risk of macular degeneration. The biggest victims of LEDs are children under 10 years of age. Children of this age have neither cloudy lenses nor macular pigment, so they lack the ability to resist blue light.

0603, 0805, 1210, 3528, 5050 refer to the size of surface mount SMD LEDs. For example, 0603 refers to a length of 0.06 inches and a width of 0.03 inches. But please note that the 3528 and 5050 units are metric. The following is a detailed introduction of these specifications:

Light-emitting diodes are commonly used light-emitting devices that emit energy through the recombination of electrons and holes to emit light. They are widely used in the field of lighting. Light-emitting diodes can efficiently convert electrical energy into light energy. LED lamps and lanterns generally have the characteristics of long life, good lighting effect, and energy saving. Because of so many characteristics that are superior to other traditional lamps, they have a wide range of uses in modern society, such as lighting, flat panel displays, and medical devices. However, a major problem facing LEDs now is the production cost of LEDs. Because the cost cannot be saved and reduced, the price of LED lamps is generally higher, which is also an important factor restricting the promotion of LEDs. Yijingyuan Optoelectronics continues to make breakthroughs in the technical field, and strives to reduce costs under the premise of ensuring quality, and has achieved the goal of reducing sales prices. It is expected that Yijingyuan Optoelectronics, and many other LED light-emitting diode chip lamp beads factories can break through the technical difficulties as soon as possible, so that LED lights will be more widely popularized and used.

The surface treatment of the product can have different effects, such as: hot bending process, silk screen (whole or part), blister, engraving, CNC cutting. For all products, we adopt strict quality control to ensure the good quality of our products. For many years, under the premise of focusing on quality, we have always had a good cooperative relationship with customers.
