How to judge the LED tube light

The main features of LED tube is high quality, durable , energy-saving, the adjustment range of projection angle is large , 15W brightness of the LED tube light is equivalent to that of an ordinary 40W fluorescent , resisting high temperature, moistureproof and waterproof , leakproof . Use voltage : 110V, 220V, jacket optional glass or PC material . the head of the lamp is the same as the ordinary fluorescent.

LED Commercial lighting

LED tube light uses the latest LED technology , digital design, saving up to 15% , the light intensity of 12W LED fluorescent is equivalent to 40W fluorescent, the life of the LED tube is 5 times more than that of the fluorescent lamp , almost the maintenance is free , it is no need to always replace the lamp , ballast, starter . Green semiconductor light source , soft light, pure spectrum is conducive to the our eyesight and physical health . 6000K cool white light gives us the cool visual experience, humane illumination differences help to focus and improve efficiency.

Quality

The quality of LED tube depends on several aspects

1 what is the chip used by the LED tube light? The chip directly determines the performance of the LED tube, such as color temperature, color rendering.

2, what is the power ? what is the type of power , power factor , anti-surge , EMC? The  Power Supply that is good or bad influence the working status of chips LED fluorescent,

how to choose the LED fluorescent?

3.whethe structure design of the LED tube light is reasonable , the key of the structural design is how the design of heat sink, which reflects that the heat dissipation is good or bad, not good ,after thermal stability, the lamps is of high temperature, leading to the chip is working under high temperature and cause performance degradation .

4 . lens design of the LED tube light, a good lens has the accurate light distribution , the lens whose the optical loss rate is low can reduce the optical loss when the visible light through the lens , which is very important and crucial . More accurate light distribution can ensure us with a minimum of power to achieve the best lighting effects .

Precautions

In view of the above, we should comprehensively judge to determine a good LED tube light.

How to distinguish the quality of the LED ceiling light

Although the brand of the current domestic LED ceiling light is more, the overall strength are of different level, however, many of them are high-quality LED Ceiling light brands. So which LED ceiling light is good , how to buy it , we can consider from the following aspects.

How to buy LED Downlight

Tools / materials

LED Downlight

Methods / steps

1.Inspect the lamp radiator :

the speed of lamp bead disposing the heat determines the lumen level and service life of the entire lamp. The  Lamp beads work for a long time under the high temperature, the light fades quickly , the life is very short , but the ceiling light whose brightness is too bad would not achieve accent lighting effects.

For the solution of the LED ceiling radiator, the mainstream is integral heat sink, there is a lamp beads pulsing a single cooling column, there is a additional fan.

More recognized way of the current user is a single lamp beads pulsing a cooling column. In this way, the column quickly circulate the heat generated by each lamp beads out to ensure timely disposing the heat . The overall heat sink is that pass the heat all the light beads generate to the aluminum plate, and then through the radiator circulating , cooling at a slower pace .

The size of the radiator and the quality of aluminum affects the speed of cooling , but also affect the price of the whole lamp .

2.inspecting the lighting power ( commonly known as the transformer ) :

the quality of transformer also determines the entire life of the lamp , there is no problem with the lamp beads using more than 30,000 hours, but if the transformer is broken , then the whole lamp will can not be lightened up. the electronic components , the design the transformers use determines the efficiency of the transformer , power factor, stability, temperature rise , life.

If we do not understand the knowledge of the components , we can initially judge from the transformer size, weight, and consulting the electrolytic capacitors using by manufacturer and other aspects. The  price of LED ceiling light is different , the quality of the transformer accounts for no small proportion .

3.Understanding of the brand and packaging of the lamp beads :

The lighting effect of the LED ceiling light depend on the Quality of the lamp beads, the packaging technology affects the quality of lamp beads , cooling and other key factors. LED chips are the United States chips, Taiwan chip , homemade chips. Different brands, the price difference is large, lighting effects are also great differences .

We  can consult the manufacturer to learn the programs of the lamp beads , depending on the extent of the manufacturer’s integrity . Particularly for the low price of the LED ceiling light , a lot produced by using the defective chip on production lines, inconsistent color temperature , brightness difference , life is short, we need to pay attention to .

Precautions

Concluded by the above points, we can determine how is the quality of the LED Ceiling Light so that buy the ideal product  in the market.

What’s the fifth obstacles hindering the pace of progress of LED lighting

Under the background of advocating energy saving and low-carbon economy, many companies have stepped into the LED projects . LED lighting applications lead to industry fanatical tide . MIIT data display, LED industry investment maintains rapid growth , LED lighting has become an investment hot spot.

LED lighting

Definitely, the LED lighting prospects is bright, but the problems the industry currently  arise will become a stumbling block on this road , which is hindering the development of the industry .

First, the high prices, the market reaction is colder

The biggest problem is that the price is too high. The cost of LED lights is mainly from three aspects, first of all,the chip is about 30% of the total cost ;second,the drive is about 60% of the total cost , the third is lamps and lamp shells , about 10% of the total cost. The prices of the chips have begun to be cut , the prices of the current chip fall by 30 % compared to that of during the same period last year, which is equivalent to that the cost of LED lights down by 9%. That is LED lights that are a hundred dollars fall to a few dollars , which is difficult to touch the consumer desire to buy .

One dealer said, now who engage in the wholesale and retail generally do not prefer to sell LED lights. Because the gap between the price of LED light and energy-saving lamps and incandescent is too large . If the price of 3W LED lamp is 20 yuan , 7W ‘s 90 yuan , while the energy-saving lamps is only 10 yuan, not to mention the incandescent that just need a dollar.

Second, the technology is not mature , but the quality isn’t ideal

Domestic enterprises are mostly traditional manufacturers specialize in LED lamps, which are lack of upstream LED technology , just outsourcing LED light source for only the simple fixture assembly . The insiders disclosed that at present 90% of the LED business losses, because many domestic manufacturers are lack of core technology, innovation and R & D investment is very small. ” it is nearly impossible to see the LED light that is more than 50,000 hours life on the market . Additionally , the lights incandescent emit look like the sun , some LED lights have shadows. Moreover, the appearance of a number of domestic LED lighting is not comparable with the imported products . ” the official said.

Third, low trade barriers and lack of relevant standards

The existing standards of LED lighting industry is confusion, the barriers is low to entry , many enterprises, market jumbled . At present, LED lighting standards is imperfect , which is mainly simple copied according to the standard of the traditional lighting fixtures, standards targeting to the energy-saving , high luminous efficiency ,life and other is limited, so there is no way to judge the quality of the product , resulting in mixed enterprises .

Fourth, the collective effect of sales terminal is not formed

The sale terminals is relatively fragmented , the investments are mainly concentrated in the upstream . Currently, there are thousands of companies professionally managing and manufacturing LED lighting , but few businesses specializing in LED products in the end of the market , LED stores and sales channels has not yet formed the integrated effect in the market . As the core is chip deciding the LED prices, resulting in many large enterprises investing LED chip , there are 80 to 90 enterprises investing in LED chip in the domestic market. The more the LED downstream enterprises, the smaller invest, which has really made ​​there has almost been no brand effect , it is understood that there is no one lighting company whose terminal sales is over billion , majorities are some small enterprises.

Fifth , inadequate literacy for LED lighting,

Many people do not understand what the LED lights are, even though many staff  do not know LED lights at the mall. Since incandescent is of appropriate light intensity and low prices , as the consumers also believe that the quality of the LED lamps lighting isn’t better than the energy-saving lamps and incandescent ,there is too less light colors to choose, start-up speed is relatively low , even few people are worried about that the flashing fluorescent lamps can cause migraine headaches and epilepsy . Let alone to identify the authenticity of the lamps .

Although there are so many obstacles hindering the pace of progress of LED lighting, however, speak louder than words, LED lighting that uses  the light emitting diodes as a principle for the lighting is the third generation of lighting, as the semiconductor technology and excellent energy saving effect is in line with the current social environment advocating low-carbon and energy,

Nowadays,the LED flood light such as  the rechargeable portable LED flood light 10W and LED tube light are the most widely used as the representatives of the decorative lighting  and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while  low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection.
