LED lighting performance must be detected project

1, luminous intensity detection

Light intensity is the intensity of light, refers to the amount of light emitted in a particular angle. Due to the concentration of LED light, the inverse square inverse law is not applicable at close range. The CIE127 standard provides two measurement averaging methods for measuring light intensity A (far-field conditions) and measuring conditions B (near-field conditions) To the light conditions, the two conditions of the detector area are 1cm2. Normally, the standard condition B is used to measure the luminous intensity.

2, luminous flux and light efficiency testing

Luminous flux is the total amount of light emitted by the light source, that is, the amount of light. Detection methods include the following two kinds:

(1) integral method. In the integrating sphere, the standard lamp and the lamp under test are sequentially lit, and their readings on the photoelectric converter are respectively Es and ED.

(2) spectrophotometry. Under the same conditions of the lamp under test Spectra were measured, compared to calculate the luminous flux of the lamp under test.

Luminous efficiency is the ratio of the luminous flux emitted by a light source to the power consumed by it, and the luminous efficacy of the LED is usually measured by a constant current method.

3, the spectral characteristics of testing

The spectral characteristics of LED detection, including spectral power distribution, color coordinates, color temperature, color rendering index and so on.

The spectral power distribution means that the light of a light source is composed of a plurality of color radiations of different wavelengths and the radiation powers of the respective wavelengths are also different in size. Such different wavelength distributions are called the spectral power distribution of the light source. The use of spectrophotometer (monochromator) and standard light source for comparison and measurement.

Color coordinates are digitally represented on the graph the amount of light emitted by a light source. There are many coordinate systems for color coordinates, usually X, Y coordinate system.

Color temperature is the amount of light color table (appearance color performance) that the human eye sees. When the light emitted by the light source is the same color as the light emitted by the absolute black body at a certain temperature, the temperature is the color temperature. In the field of lighting, color temperature is an important parameter to describe the optical characteristics of a light source. The theory of color temperature stems from blackbody radiation and can be obtained from the color coordinates of a blackbody locus through the color coordinates of the light source.

The color rendering index indicates that the amount of light emitted by the light source correctly reflects the color of the illuminated article, usually expressed as the general color rendering index Ra, which is the arithmetic mean of the color rendering indices of the eight color samples by the light source. Color rendering index is an important parameter of light source quality, which determines the application of light source, improve the color rendering index of white LED is one of the important tasks of LED research and development.

4, light intensity distribution test

Light intensity with the spatial angle (direction) and the relationship between the said pseudo-light intensity distribution, by the distribution of the closed curve is called the light intensity distribution curve. Due to the large number of measurement points and the data processing at each point, an automatic photometer is usually used for the measurement.

5, the temperature effect on the optical characteristics of LED

The temperature will affect the optical properties of the LED. A large number of experiments can explain the temperature of the LED emission spectrum and color coordinates.

6, the surface brightness measurement

The brightness of a light source in one direction is the luminous intensity of the light source in the projection area of the unit in this direction. Generally, the surface brightness meter and the aiming brightness meter are used to measure the surface brightness, and the aiming light path and the measuring light path are two parts.

7, LED lamps electrical parameters of the measurement

Electrical parameters include forward, reverse voltage and reverse current, LED lamps related to the normal work, is to determine the merits of the basic performance of LED lamps one of the merits. LED lamps have two kinds of electrical parameters of measurement: the current under certain circumstances, the test voltage parameters; voltage under certain circumstances, the test current parameters. Specific methods are as follows:

(1) forward voltage. A positive current is applied to the LED lamp to be tested, with a voltage drop across it. Adjust the current value to determine the power supply, record the relevant readings on the DC voltmeter, which is the forward voltage of LED lamps. According to common sense, LED forward conduction, the smaller resistance, the use of ammeter external connection method more accurate.

(2) reverse current. To be tested by the reverse voltage LED lighting, regulating power supply, ammeter reading is measured LED lamps reverse current. And the same measurement of forward voltage, because the LED reverse conduction larger resistance, the use of ammeter connection method.

8, LED lamps thermal characteristics of the test

Thermal characteristics of LED, LED optical properties, electrical properties have a significant impact. Thermal resistance and junction temperature, LED2 is the main thermal characteristics. Thermal resistance refers to the thermal resistance between the PN junction and the surface of the housing, that is, the ratio of the temperature difference along the heat flow path to the power dissipated on the channel. The junction temperature is the temperature of the PN junction of the LED.

Methods of measuring LED junction temperature and thermal resistance are generally: infrared microscopy method, spectroscopy, electrical parameter method, thermal resistance scanning method. The use of infrared temperature microscope or miniature thermocouple measured LED chip surface temperature as LED junction temperature, accuracy is not enough.

The commonly used method of electrical parameters is the use of LEDPN junction forward voltage drop and PN junction temperature into a linear relationship between the characteristics of different temperatures by measuring the forward voltage drop LED junction temperature obtained.

China’s penetration of LED lighting in 2020 reached 60% -70%

China LED general lighting market in 2016 reached 204 billion yuan, LED penetration rate of 44%, the current use of LED lights the same cost with the traditional light bulbs, is expected in 2020, China’s LED lighting penetration rate of 60% -70%, LED General lighting in the next few years will maintain double-digit growth.

China's penetration of LED lighting in 2020 reached 60% -70%

The competition pattern in the lighting industry is fragmented. At present, the market share of the industry leader is only about 3%. The reason for this is mainly because, in the traditional light source era, the light source was monopolized by three big factories: Philips, GE and OSRAM. Competitiveness. China’s grasp of LED technology has broken the original competitive landscape, greatly reducing the technical threshold of light source, and the transfer of industrial chain right to lamp manufacturers closer to the terminal. Lamp manufacturers have the opportunity to improve through product design, channel management and brand marketing Market share.

On the other hand, with the improvement of national income, the demand for quality of life of Chinese people continues to increase. When choosing lamps and lanterns, more attention is paid to brand and product design. The living space of cottage products is compressed. As the cost of raw materials increases, Environmental requirements increase, many small factories have also been forced to withdraw from the market. In fact, LED lighting penetration rate has risen rapidly since 2012, the first echelon lighting business market share steadily increased with the withdrawal of European and American manufacturers and cottage small plant, the future is expected to accelerate this trend.

After years of development, the lighting market in the United States has formed several luminaries manufacturers with revenues of several tens of billions, such as Cooper, Haber and Brighton Lighting. With the favorable competitive landscape, the LED lighting market in China is expected to emerge soon Even several leading manufacturers comparable with the international giants.

Which of the five main factors will affect the life of the LED lamp?

If you use a light source for a long time, you will have great economic benefits and reduce your carbon footprint. According to the system design, the reduction of luminous flux is a normal process, but it can be ignored. When the luminous flux is reduced very slowly, the system will remain in good condition without long maintenance.

Which of the five main factors will affect the life of the LED lamp?

Compared to other light sources in many applications, LEDs are undoubtedly superior. In order to keep the system in good condition, the following five factors need to be considered.

Effectiveness

LED lamps and LED modules are manufactured and driven within a specific current range. According to its characteristics, it can provide LEDs with current ranging from 350mA to 500mA. Many systems are driven in high value areas of this current range.

Acidic conditions

In some acidic conditions, LEDs can also be easily affected, such as in coastal areas where salt content is high, in factories where chemicals or products are used, or in indoor swimming pools. Although LEDs are also manufactured for these areas, they must be carefully packed into fully enclosed housings with high IP protection.

Heat

Heat will affect the LED’s luminous flux and life cycle. Radiator can prevent the system from overheating. Warming of the system means that the allowable ambient temperature of the LED lamp is exceeded. The life of the LED depends on the ambient temperature.

Mechanical stress

When manufacturing, stacking, or simply manipulating LEDs, mechanical stress can also affect the life of the LED lamps, sometimes completely destroy the LED lamps. Pay attention to Electrostatic discharge (ESD), as this can cause transient but high-current pulses that damage the LEDs and LED drivers.

Humidity

The performance of the LED also depends on the humidity of the surrounding environment. Because in wet environments, electronic devices, metal parts, etc. tend to break down quickly and begin to rust, try to keep the LED system away from moisture.
