The LED lamp

- Jun 27, 2019-

LED lamp post is a new product of LED white light, which is also called oxtail light source in the market. Also called filament LED, LED light bar, LED light source to achieve a certain light and lighting area, the need to install optics lens, not only affect the light effect, and can reduce the LED its energy saving effect, large Angle LED the emergence of the filament, to solve the above problem, truly realized the full Angle 360 °, don't need to add a lens can achieve stereo illuminant, brought unprecedented lighting experience.

LED lamp post advantage:

1, 360; Luminous stereo light source.

2. Blue light chip, red light chip, yellow and green powder, white light packaging process.

3. Integrated high-voltage drive maximizes power factor and minimizes lamp cost.

4. High quality light source, color rendering index above 90, light effect above 110lm/W.

5. Complete transparent base material is adopted to match the new 360 packaging technology.

6. Apply our company's independent research and development of fluorescent gum molding process, with high yield.

7. Brand new light vision, experience the original incandescent lighting environment.

How LED lamp posts work

LED lamp post with red, green, blue three kinds of blue LED light source, four rows of LED light speed through the milky transparent round tube projected to the digital lamp post inner surface, after several reflection refraction, formed a mixed color transparent wall, achieve decorative lighting effect.

The lamp post is connected with a digital circuit, and the external controller controls it accordingly. Through modulating the working mode of the controller, various colors and states can be changed according to certain laws. 

The heart of an LED is a semiconductor wafer, one end of which is attached to a stand, one end is negative and the other end is connected to the positive end of the power supply, so that the entire wafer is encapsulated in epoxy resin. A semiconductor chip consists of two parts, one is a p-type semiconductor, in which the holes are dominant, the other is an n-type semiconductor, and the other is dominated by electrons. When the two semiconductors are connected, they form a p-n junction. When a current is applied to the chip through a wire, the electrons are pushed into the p-zone, where they recombine with the hole and emit energy as photons, which is how leds glow. And the wavelength of light, the color of the light, is determined by the material that forms the p-n junction.

A single LED bead works at a low voltage (about 3V) and a low current (about a few milliamperes), producing a very weak light. Many LED beads need to be connected in series or in parallel; At the same time, a single LED bead conducts electricity in one direction. In order to make full use of positive and negative half cycle current of alternating current, an integrated circuit chip is needed to convert the ac 220V power supply into a direct current that can match the voltage and current of the LED set, so as to meet the requirements of the LED bead assembly and make it emit light normally.
