LED bulb lamp brief introduction

 

The largest market for LED bulb lighting is the civil market, and the most commonly used by the public is the bulb, so LED bulb is a new type of green light source to replace the traditional incandescent bulbs, because people are used to bulbs, in order to do a better job of the fourth generation of green lighting sources, this alternative to incandescent bulbs shape is also adopted. The bulb caps of LED bulbs produced by Green Hengming Optoelectronics are also spiral. Since 2011, LED bulbs have been made of high-power LED chips. To prevent glare problems, the enclosures are usually made of ground glass or acrylic. It can be directly driven by the power supply. Most products have wide voltage input and can be input from AC8~269V.

 

The traditional incandescent lamp (tungsten filament lamp) has high energy consumption and short life. Under the environment of global resource shortage, it has been gradually banned by the governments of various countries. The substitution product is the electronic energy-saving lamp. Although the electronic energy-saving lamp improves the energy-saving effect, it is contrary to the environmental protection because it uses many heavy metal elements which pollute the environment. The general trend of nursing. With the rapid development of LED technology, LED lighting has gradually become the new choice of green lighting. LED is far superior to traditional lighting products in terms of luminous principle, energy saving, and environmental protection.

LED bulb lamp Detailed explanation

 

structure

First, as follows:

A bulb is made up of seven parts, the top of which is a glass cover, the cover is clamped on the base, there will be a hole on the base, the base connected to the heat conduction seat, the heat conduction seat connected to the radiator, on the lamp head connected to the drive power, luminous is the lamp beads.

 

The highest cost of a bulb can be said to be the drive power, without which the bulb will not light. And for the quality of a bulb, the most important thing is the radiator, the driving power, and the lamp beads.

 

LED bulb lamp energy conservation

With the rapid development of LED lighting technology, the energy-saving effect of LED bulb lamp has reached a very high level. Under the same light efficiency, energy consumption has been reduced to 1/8 of an incandescent lamp and 1/2 of the electronic energy-saving lamp, so LED lighting products will replace the traditional lighting products of the energy-saving lamp is the general trend.

LED bulb lamp Design

Since 2011, the direction of bulb illumination on the market is unchanged. If it needs to be changed, it needs to be changed on the matching lamps. This will increase the cost of the product and make it inconvenient to use. A new 360-degree turning LED bulb can rotate in any direction to meet various needs, changing the ordinary bulb can only be used. The limitations of fixing a place on a fixed basis.

They will be widely used in shopping malls, office buildings, hotels, exhibition halls, conference rooms, hospitals, window display, home and other places, especially suitable for luxury high-standard large space lighting decoration.

 

Application characteristics

 

  1. Energy-saving research data show that since LED is a cold light source, semiconductor lighting itself has no pollution to the environment. Compared with the incandescent lamp and fluorescent lamp, the energy-saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 for ordinary incandescent lamps and 1/2 for fluorescent lamps. If LED is used to replace 50% of the traditional incandescent fluorescent lamps, the electricity saved in China is equivalent to the total power generation of a Three Gorges Power Station every year, and its energy-saving benefits are considerable.

 

2, healthy LED is a kind of green light source. LED lamp DC drive, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and has a strong luminous direction; good dimming performance, color temperature changes will not produce visual errors; cold light source heat low, can be safely touched; these are incandescent lamp and fluorescent lamp cannot reach. It can not only provide comfortable lighting space but also meet the needs of people’s physical health. It is a healthy light source for protecting vision and environmental protection.

 

  1. Humanization undoubtedly, the relationship between light and people is an eternal topic. “People see the light, I see the light.” It is this classic phrase that has changed the understanding of numerous designers on the lamp. The highest realm of lamps and lanterns is the “shadowless lamp” is also the highest embodiment of humanized lighting. There is no trace of common lamps and lanterns in the room so that people can feel the light but can not find the light source, reflecting the perfect combination of light and human life humanized design.

LED bulb lamp Cost performance

 

If our 3W’s LED lamp cup is 90 yuan, the 12W energy saving price in the market is about 20 yuan.

 

If we turn on the light 8 hours a day, the energy-saving lamp 12 W is 0.096 degrees a day, and 8 hours our 3 W LED lamp is only 0.024 degrees a day, that is, 0.072 degrees a day, saving 26.28 degrees a year.

 

The life of LED lamp cup is longer than 50000 hours. The energy saving lamp is only about 5000 hours (only 10% of China’s products can achieve this effect). In contrast, 1 year of 12W’s energy saving lamps will probably cost 2.

 

So a 3W LED cup saves 26.28 degrees * 1 yuan * 1 degree * 2 * 20 yuan / = 66.28 yuan a year compared with the 12W energy-saving lamp everyone uses.

 

8 hours per day, LED lamp cup, two years to earn the cost. The life of the LED lamp cup is longer than 50000 hours, and the household can probably take about 10 years. In the last 8 years, the electric charge and the cost of the lamp were earned. It can be considered how much the cost and the time cost of the 2 12W energy saving lamps per year are spent. There are many harmful heavy metals in ordinary energy-saving lamps.

 

LED bulb lamp Choose

 

  1. the LED bulbs of several W can replace several W energy saving lamps.

 

  1. the number of W marked by most manufacturers is the use of several 1W beads instead of the actual W number of the whole lamp.

 

  1. the confusion of LED chips.

 

  1. the appearance is the same, and the price is very different. I don’t know what’s the difference.

 

  1. Where is the LED bulb used?

 

LED bulb lamp Matters needing attention

 

The ultimate rule for buying LED bulbs is the price: there’s a very simple way to “compare” them. First, take a look at the price of the company’s LED lamps, and then go to Taobao to see the price or the lamp store on the market to see the price. The prices of large companies are generally high, but their things must be good. But considering the income of the Chinese people should not be easily affordable. Then the website platform and the market prices of lamps and lanterns shop, and then take the median value is almost always able to do the quality of the past LED light.
