In-depth Demand Report | Disassembling Outdoor Flood Lighting Fixtures

The use of solar street lamps, in summer or in winter, some of the highest temperature in summer would reach 40 degrees, and the winter will be low to 20 degrees below zero, this time, the solar street light battery charging capacity could reach the normal temperature of 80%, or less, is bound to make the battery discharge, the use of hours to reach the design standard.

In order not to let this situation, we need to give corresponding voltage compensation for battery temperature changes called & other;
Temperature compensation & throughout;
。

We at the time of installing solar street light, the first to determine the controller to have temperature compensation, if it is a separate controller and battery placed, as necessary to factory customize the controller of temperature sensing lines outside, so even if the controller is separated from storage battery, the controller can also be detected by temperature sensor line real-time environmental temperature of the battery, give the most accurate voltage compensation.

Many controller will now considering temperature compensation, the controller itself a temperature sensing probe, the purpose is to sense the temperature of the environment after the real-time compensate the voltage to the battery.

Controller of temperature sense perception is their surroundings temperature, when the battery and solar street lamps controller together, the compensation voltage is accurate.

In order to guard against theft, but also prevent excessive temperature change battery solar street lamps are mostly buried underground, so the controller of the environment temperature and the temperature of the battery has a possible error is very big, of course, the compensation of voltage compensation is a mistake, will cause the battery overcharge or discharge, which reduces the service life of the battery, or even damage.

visual measurement is the core of image acquisition and processing.

All information from the image, in addition to the quality of the image itself, the light source spectral distribution is another important factor affecting the quality of the visual system image.

Colour vision measurement is different from the gray level vision measurement, it is a simple grayscale order change information to the rich color 3 d information.

Lighting source and surface reflection spectral characteristic determines the object to be tested visual measuring system is collected by the spectral distribution of light energy, even if the structure and the common way of lighting light source, because the luminescence spectra of different image will have the very big difference.

So, full spectrum light source or a specific spectrum of light source in the extraction of target features such as color, outline information plays a very important role.

How to use light color features to get the best effect of contrast.


images has been a colour vision measuring lighting system the important direction of development, monochrome leds has small volume, easy integration, simple drive and the advantages of good monochromaticity, than ordinary light luminous intensity, peak wavelength in recent years, half wave bandwidth performance got very big improvement.

The special requirements of colour vision measurement system, the author of this paper, combining with the advantages of red, green and blue leds, designed and produced a more color characteristics, digital adjustable brightness, uniform irradiation LED light source.



2 LED light source system 2.


1 design principle and structure analysis according to the color combination of four basic rules: continuous change rule, the rate of complementary color, light, demitint law and replacement rate, good monochromaticity of red, green, blue three colors, LED by independent precisely control the luminous intensity, can simulate various kinds of uniform and stable color.

When choosing LED wavelengths, should make the wavelength of 3 kinds of color to match the camera 3 kinds of spectral peak.


can meet the requirements of the light source system should adopt forward lighting technology, namely light irradiation on the target object, one side of the light source camera receiving the reflection of light from objects, so the most conducive to the extraction of color information of the measured target and the characteristics of surface detail.

In order to solve the problem of projection and irradiation uniformity problem, we adopt scattered light illumination, namely make 3 kinds of color of light within one and a half spherical reflector diffuse reflection occurs, secondary lighting using reflected light.

Semiconductor Lighting Technology Evaluation alliance and China semiconductor lighting/LED industry and application Alliance released four LEDs in Beijing in May 30, including safety requirements, performance requirements, specification classification and performance requirements for non-directional Self-ballasted LED lamps. the lighting industry is in urgent need of standards.
According to the National Electric Light source quality supervision and inspection center (Beijing)
Introduction, China's LED lighting industry has many problems, such as large number of enterprises, small scale, uneven product quality, etc. Product exports often face obstacles such as different standards and certifications in the international market.
The four standards released this time will fill the standard gaps in China's related product fields and standardize and guide the sustainable and healthy development of enterprises. LED is short for light emitting diode.
Compared with incandescent lamps and energy-saving lamps, LED lamps have the advantages of more energy saving, longer service life and less pollution, which represent the development direction of lighting products in the future.
China is a major producer of LED lighting, with about 90% of its output, and its products are widely sold to the international market.
In recent years, LED lighting equipment has been widely used in roads, schools, shopping malls and hotels in many cities in China. National Electric Light source quality supervision and inspection center (Beijing)
This year, the proposal document for LED lamp specification classification has been submitted to the lighting products Technical Committee of the International Electrotechnical Commission, which has been generally recognized by members of various countries.
This will greatly improve China's participation and initiative in the formulation of international LED standards and play its due role in the formulation of international standards for related products.

LED lighting market development on the surface looks like rollerblading, but virtually every industry also has its own difficulties, LED lights, such as uneven and said market, also can appear homogeneity and so on questions, there is also a technical problem, take a look at below LE



LED lighting market development on the surface looks, but virtually every industry has its own difficulties, LED lights, such as uneven and said market, also can appear homogeneity and so on questions, there is also a technical problem, take a look at below LED lights have what kind of difficulties in the promotion.



LED lighting technology to gradually increase, more efficient, unit costs decline, the industry think that next year will officially enter the first year of LED lighting, lighting market before is given priority to with Europe and the United States, according to research firm, points out that mainland lighting market scale has officially overtook the us last year, and the Chinese government actively promote & other;
Ten city wan light & throughout;
Also expanded to & other;
Fifty city two million lamp & throughout;

LED street lamp project, at the same time, the LED industry in Taiwan are stepping up the layout, is expected to cannibalize the huge business opportunities, however, due to the great influence on the quality of the external environment for the LED street light, high maintenance costs, involving political and economic relations with mainland China market, LED industry can actually eat pie, remains to be seen.



the LED street light in addition to the design and the maintenance cost is higher, the industry also revealed that in private street market is controlled in the hands of the government, to win the order, in addition to participation in government bid, may also face the forces of local factions, play a little also not of ghostly part of the process, deepen into the difficulty of the street lamp market, many companies do not dispute that the size of the company will be broken this market, whether the important factors that have the small and medium-sized manufacturers show that type will be focusing on niche market directly, don't step into the LED street lamp battlefields.



big market prospect is very objective, just, of course, is the best way to prepare itself technology, and prospects the future of the LED lights market best.
