Today brings you led light source industry problems and purchase errors. In the rapid development of science and technology now, led light source and gradually inseparable from our lives, in the new and old alternation today, there is no doubt that led light source occupies the dominant position of daily lighting, which brings about the led industry problems and led purchase problems, the following to solve these problems bring us doubts.

LED light source industry three major problems

LED light source problem one: price

The price of LED products has always been one of the issues of concern in the industry, high will be considered not close enough, low will be said to be self-lowering status, so the industry lacks a clear and clear standard, the price has been in the embarrassing position of "high not low", how much the product price is subject to cost and market constraints at the same time, and has become a "heart" problem, Business owners sell as much as they order, while for the consumer market, it seems that people who buy products for any amount of money have it.

LED light source problem two: policy

The United States began to completely ban incandescent lamps, which will be a big opportunity for LED products to compete for market space, and this kind of favorable or disguised favorable policies for the LED industry in recent years, the "policy poisoning" makes the LED industry overly dependent on government support, although everyone understands that the future of the industry depends on the commercial market, However, most companies are still waiting to see what the government is doing in the process of development, and change their focus as soon as they have the opportunity. Most LED companies have "poisoning" disease, imagine can stand on the shoulders of giants, who will not be willing to stand?

LED light source problem three: concept

Backward concept involves many aspects, channels, design, brand, marketing and other aspects can no longer be measured and thought by the old concept, there are enterprises from the traditional lighting transformation, although it has channel advantages, but the channel or the original project to carry out adaptive reform is also necessary. What kind of consumers are we dealing with? How do they learn about the product? And through what channels to buy products? In the continuous development of various technologies today, we carry the name of this high-tech industry, how should we go ahead?

LED light source purchase three misunderstandings

LED light source misunderstanding one, the expectation of actual service life is too high

LED manufacturers expect LED life to reach 100,000 hours MTBF (mean time to failure, the standard used by traditional lamp manufacturers to measure the life of light sources). However, like all basic light sources, the luminous flux lumens of leds also decay with time. So, although the LED light time can be very long, MTBF is not the only consideration to determine the service life. The attenuation of LED lumens is affected by many environmental conditions such as ambient temperature, humidity and ventilation. Lumen attenuation is also affected by control, thermal management, current levels, and many other electrical design considerations.

Many salesmen may provide customers with some vague information when promoting LED for some reason, causing misleading, such as the service life of LED in about 100,000 hours, where 100,000 hours refers to the manufacturer's expected service life of LED. However, as a lighting source, the brightness of the lamp has a gradual decay and darkening process (such as fluorescent lamps, energy-saving lamps), this process is referred to as light decay. Therefore, consumers in the purchase of LED to pay attention to its light decay speed, rather than the use of time, consumers must not expect too much of the actual service life.

LED light source misunderstanding two, the actual luminous Angle as the effective Angle

The luminous Angle of LED is divided into effective Angle and actual luminous Angle. The luminous intensity value is the effective Angle between the direction of half of the axial intensity value and the luminous axis (normal). Twice the half value Angle is the Angle of view (or half power Angle) is the actual luminous Angle. Angles other than half the axial intensity are not counted as effective angles in practical applications because the light is too weak.

Therefore, consumers should pay attention to the actual luminous Angle of the product when purchasing products, when calculating the number of products used in the project, the actual luminous Angle shall prevail, and the effective luminous Angle can only be used as a reference value.

LED light source error three, the greater the power, the higher the brightness

The brightness of the LED is measured by the luminous intensity, which refers to the luminous intensity in the direction of the normal (the cylindrical luminous tube refers to its axis), that is, the luminous flux emitted by the unit solid Angle, the unit is Candela (cd). Due to the small luminous intensity of the general LED, the luminous intensity is commonly used as a unit of millicandela (mcd). In general, the light source will radiate its luminous flux in different directions with different intensities, and the visible light radiation intensity released by the unit solid Angle in a specific direction is called light intensity, referred to as axial brightness.

The concept of electric power is introduced from the amount of work done by the force in the same time, the current does work fast, the electric power is large; The current does work slowly, the electrical power is small, or in the same time, the more work the current does, the greater the electrical power, on the LED, not the greater the power, the higher the brightness of the product. Taking the three-lamp red LED of Yimei Electronics as an example, when the axial brightness is 1200mcd, the current is 40ma and the power is 0.48W; Three-lamp white LED in the same brightness, the current is 18ma, power is only 0.24W; It can be seen that the power of the two kinds of light is different at the same brightness. Therefore, when consumers buy LED lamps, they should pay attention to its axial brightness, rather than power.

The above is the three major problems of LED light source industry, LED light source purchase three misunderstandings, I believe you also understand, in fact, the purchase of led also has a very important point, that is, quality, good quality can bring led light source very long life, which is also an advantage of led light source, here recommend Liyang Co., LTD., specializing in the production of led light source equipment, Be trustworthy.
