LED Lamp Good Seismic Performance

Sep 05, 2017

LED Lamp is an electroluminescent semiconductor material chip, with silver glue or white plastic curing to the bracket, and then use a silver wire or gold wire to connect the chip and circuit board, surrounded by epoxy resin sealed, to protect the internal core Role, and finally install the shell, so the LED lamp seismic performance is good.

LED light-emitting diode, is a power can be converted into visible light of the solid-state semiconductor devices, it can be directly converted into light. The heart of the LED is a semiconductor chip, one end of the chip attached to a bracket, one end is negative, the other end of the power supply connected to the positive, so that the entire chip is encapsulated by epoxy resin.

Semiconductor chip consists of two parts, part of the P-type semiconductor, in which the dominant hole inside, the other end is the N-type semiconductor, mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current through the wire acting on the chip, the electron will be pushed to the P area, in the P area with the hole in the electronic composite, and then will be issued in the form of photon energy, which is the principle of LED light. And the wavelength of light is the color of light, which is determined by the material that forms the P-N junction. LED can be issued directly red, yellow, blue, green, blue, orange, purple, white light.

First, the characteristics

1, energy saving: white LED energy consumption is only 1/10 of incandescent, energy-saving lamps 1/4.

2, longevity: life of up to 100,000 hours or more, the ordinary family lighting can be described as "once and for all."

3, can work in high-speed state: energy-saving lamps if the frequent start or turn off, filament will be black, and soon broken, so more secure.

4, solid-state packaging, are cold light source type. So it is well transported and installed and can be installed in any miniature and enclosed equipment, not afraid of vibration.

5, led technology is changing in progress, its luminous efficiency is amazing breakthrough, the price is constantly reduced. A white LED into the family's era is coming quickly.

6, environmental protection, no mercury harmful substances. LED bulb assembly parts can be very easy to disassemble, no manufacturers can be recycled through other people.

7, with light technology to LED point light source for the surface light source, increase the light side, eliminate glare, sublimation visual effects, eliminate visual fatigue.

8, lens and shade integrated design. Lens at the same time with the role of light and protection, to avoid duplication of light waste, so that more simple and beautiful products.

9, high power led plane cluster package, and radiator and lampholder integrated design. Fully guarantee the led cooling requirements and life, from the fundamental to meet the LED lighting structure and shape of any design, very distinctive features of LED lamps.

10, significant energy saving. Using ultra-bright high-power led light source, with high efficiency power supply, more than 80% energy saving than traditional incandescent, the same power brightness is 10 times the incandescent lamp.

11, long life of 50,000 hours or more, more than 50 times the traditional tungsten lamp. LED using highly reliable advanced packaging process - eutectic welding, full protection of LED long life.

12, no strobe. Pure DC work, eliminating the traditional light strobe caused by visual fatigue.

13, green. Does not contain lead, mercury and other pollution elements, the environment without any pollution.

14, impact resistance, strong resistance to lightning, no UV (UV) and infrared (IR) radiation. No filament and glass shell, no traditional tube fragmentation problem, no harm to the human body, no radiation.

15, low thermal voltage work, safe and reliable. Surface temperature ≤ 60 ℃ (ambient temperature Ta = 25 ℃).

16, wide voltage range, the global common LED lights. 85V ~ 264VAC full voltage range constant current, to ensure that life and brightness are not affected by voltage fluctuations.

17, the use of PWM constant current technology, high efficiency, low heat, constant current accuracy.

18, to reduce line losses, no pollution to the grid. Power factor ≥ 0.9, harmonic distortion ≤ 20%, EMI in line with global targets, reducing the power supply line power loss and to avoid the high-frequency interference on the power grid pollution.

19, universal standard lamp, can directly replace the existing halogen lamp, incandescent lamp, fluorescent lamp.

20, luminous as the efficiency rate can be as high as 80lm / w, a variety of LED color temperature options, color rendering index, good color.

Obviously, as long as the cost of LED lights led technology continues to improve and reduce. Energy-saving lamps and incandescent lamps will be replaced by LED lamps.

The state more and more attention to lighting energy and environmental issues, has been vigorously promoting the use of LED lamps.

Second, the advantages and disadvantages

1. Thermal problems, if the poor heat will greatly shorten the life.

2. Low-end LED lights or lower power saving lamps (cold cathode tube, CCFL).

3. Initial purchase cost is higher.

4. Because LED light source direction is very strong, lamp design need to consider the LED special optical characteristics.
