LED light source compared with CFL

Can you replace the CFL with a brighter one?
From the beginning, we will start by discussing- different light resource products.
The incandescent lamp also went to called the electric light bulb, its working principle is the current through the filament (tungsten, melting temperature reached to 3000 degrees Celsius) it generates heat, meanwhile it generates light. the light is bright,from strength to strength The filament temperature is high,So called incandescent lamp.in fact , The Incandescent lamp, a large amount of electrical energy will be converted into heat, only a few (probably less than 1%, had not been calculated) can be converted into useful energy. So the power of incandescent lamp is more.
a fluorescent lamp：   fluorescent lamp or fluorescent lamp, its working principle: In a few words the fluorescent lamp is discharge tube that was involved in gas。One has process to gas discharge to releaseing ultraviolet   (main wavelength as 2537 =2537 × 10-10m). Electric energy can be converted into about 60% UV consumed. Other energy is converted into heat energy. It is generally the ultraviolet light into visible light efficiency is about 40%. So the efficiency of fluorescent lamp is about two times the same power tungsten filament lamp. （60% * 40% = 24%）.
LED lamp (Light Emitting Diode) also known as light-emitting diode, is a solid state semiconductor devices, can be directly converted into electricity to light.
LED English as a light emitting diode, LED light-emitting diode lamp beads is the abbreviation abbreviation LED, which is a popular title.
Especially The LED COB Modules tunneling is more and more popular during recent years,
LED Modules are the latest in efficient mounting systems for LED displays. Modules are compact in size, may contain several LEDs (series-parallel connection)encased in a package.Due to the integrate of the semiconductor light-emitting diode chip technology , LED photoelectric conversion efficiency to be improved, especially in high-power LED, because of its high power ,High-Power LED Modules demand for quality and Mate- rials Handling is higher. to find out more about LED products

led vehicle lights

As with LED interior lighting, which almost no heat source, no heat, greatly reduces may occur at any time of the accident in the vehicle driving, thereby ,reduce the serious security hidden danger. LED lamp life of up to 50,000 to 100,000 hours, ie over 5-10 years, may not need to be replaced during the life of the vehicle usually. LED lights can convert electrical energy into light energy directly, able to meet the needs of environmental protection and energy saving. don’t need the starters, and rectifiers for start,it can be powered light directly, energy saving Most likely a new identity., So fast does light travel that it is difficult for us to imagine its speed. as the brake lights use . In contrast, one incandescent light bulb, only to 12%-18% of electrical energy into led light, the other electric energy into heat energy. Start time is longer than ordinary incandescent bulb, typically 100-300 milliseconds,and LED start time is only a few tens of nanoseconds. Crucial for high-speed brake lights, such a time gap means difference of 4-7 meters braking distance, improving the safety of the vehicle driving.

LED solution

Several of car internal and external lighting LED driver solution
LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor devices, which can be converted directly into electricity to light. In recent years, the applications continue to expand, from the portable device backlight traditional to large size LCD display / LCD TV backlighting, automotive and general lighting field. This article will be devoted to a variety of LED driver solutions, suitable for car light, This paper will be devoted to the various LED drive scheme suitable for automotive lighting applications, and discusses some typical applications. and discuss some typical applications.   LED offers many advantages for automotive lighting applications,LED applications is very wide in car field, but can be summarized as interior lighting and exterior lighting (see Figure 1).
but simply classified into internal and external lighting lighting . External lighting as the headlight, Obe Terua, interior lighting including internal convenient and comfortable lighting and instrument panel backlight.
A lot of factors to promote the application of automotive LED lighting. With headlamp for example, the use of LED as a light source has many advantages:
1.1 to design led flexible or novel
LED physical size is very small, can be used to develop extremely compact, thin modules. Compared with halogen and xenon lights, multi-string LED module requires a smaller, simpler lens and a light-diffusing sheet hardware. And a plurality of LED light source is easier to guide,
greatly reduce the impact that project in engineering design.
1.2 light intensity and energy efficiency continues to improve LED light intensity is fast on the lift curve, showing every 18-24 months flux will double trend. LED light output has more than halogen lamps,
future LED optical performance will also be able to rival the xenon lamp.
1.3 high reliability and long life
As long as the car headlamp effective thermal management module to maintain a low junction temperature, and protect it from the switch is turned on / off, the impact of the pulse and the battery current spikes may occur during can’t affect. Expect them to continue to use in the whole life cycle of the car.
1.4 significant energy savings
Compared with other solutions, car headlamps use fuel / energy is much less. Use high efficiency intelligent power Technology / chip, rather than a number of external components required general IC, can be more energy efficient.Therefore, LED automotive lighting applications in increasing, and by many car manufacturers as a design selling point.
2 LED driver solutions compare
LED automotive lighting applications in a variety of different applications of LED current requirements also vary, so the need to combine specific application requirements, select the appropriate LED driver solution.
One of the main features LED driver solution is the steady flow in a variety of working conditions, regardless of the input conditions and forward voltage variations. Driver programs must comply with energy efficiency, form factor, cost and safety aspects of the application requirements. Meanwhile, the selected solutions must be easy to use and strong enough, to meet strict environmental application specific.The typical LED driver program in automotive applications including resistors, linear LED driver, LED driver and innovative lighting switch management LED driver. In general, according to the size of LED current in the application, in low current application of 20 to 200 mA, can using discrete components (i.e. resistance) or linear driving solutions; in the secondary current application of 200 to 500 mA, can choose linear or switch driver solutions; and in high current applications is greater than 500 mA， in general please selection switch drive solutions.
In fact, the resistance is the easiest, lowest cost ,LED current limiting solutions, but they are not “steady flow”, but the LED forward voltage variation and input supply voltage variation and lead to current changes, will be causing the LED brightness variation, simply LED maximum current limit. Although the low cost of such programs, but also the lowest energy efficiency, and the existence of LED thermal runaway screening costs and thermal runaway problem.CCR is a higher performance solution and it has more lower cost than the switch driver. suitable for LED lighting applications in current is less than 200 mA. CCR cheap and rugged, providing a constant brightness over a wide voltage range, CCR maximum operating voltage of 50 V, the battery can withstand load dump. CCR provides SOD123, SOT123 and DPAK different packages to work (125 ℃)
This solution can reduce or eliminate the generation LED filter stock, so that a lower total cost of the program. CCR maximum operating voltage of 50 V, CCR provides SOD123, SOT123 and DPAK in different packaging, can work under strict thermal environment (125 ℃), In addition, CCR does not generate electromagnetic interference, easy to design.

LED lighting project

Lighting technology: the basic knowledge about LED lighting project:
in recent years, LED lighting project received strong government support, the construction of city lighting engineering as an important measure to improve and beautify the environment of the city. What is the LED lighting project? What required to do for the LED lighting engineering?What do we care about it?
Below, we will give you a brief introduction about the basics of LED lighting engineering. before introducing the basics of LED lighting project, let’s repeat LED lighting works.LED (Light Emitting Diode), light emitting diode, is a solid state semiconductor devices, which can be directly Electricity into light. LED’s heart is an semiconductor wafer, the wafer is attached to an LED on the bracket, one end is negative, the other end connected to the power supply is Positive, so that the whole chip is epoxy encapsulated. The semiconductor wafer is composed of two parts, a Points are P-type semiconductor,it inside the hole dominated the other end is an N-type semiconductor, here is mainly electronic. ButWhen connecting the two semiconductors, to form a “P-N junction” between them. When the current through the wire into the semiconductor wafer.
Electronics will be to P area, complex in area P electrons and holes, , then it will emit energy,This is the principle of the LED light. The wavelength of light that is the color of light, forming a PN junction is made ​​of a material determined.

LED industry on the way

Perhaps mainly because of the policy supported which is given
by countries, many LED lighting companies at first fancy state subsidies.the few years,Under the drive of many interests, many companies have begun to enter the LED industry, there will be more LED companies into and The factory began producing LED product. So more and more LED lighting enterprise established, only a few years there are even more than the tens of thousands of enterprise. However, the greater the cake, the more people want to eat cake, In fact, for some enterprises, the confidence in the LED is not more to maintain in the “energy”,and so with the further deterioration of the economic crisis, the slow development of civil LED lighting penetration, while as the intensifies of vicious competition, makes a lot of LED lighting enterprises both in funds chain or market sales have experienced a bomb-attack, exposing a hidden crisis, so the closures will come.companies reported quarterly report is weakThe so-called ideas determine, to form their own brand USP Perhaps it is Because when engines impure, not really, not good at marketing planning, many Flexible LED Strip Lights companies have encountered unprecedented Waterloo, also largely affected the reputation of the entire LED lighting industry. The factory to follow its protectionist course.Therefore, I believe that, for LED lighting companies, LED lighting industry needs confidence and more importantly,the work is quickly reined in the transformation of business ideas, new understanding of  outdoor led lights from the awareness and attitude, stop given by the national policy as a means of making money at the same time Do LED lighting this feather deemed to keep everyone happy, like in my hand tightly, otherwise it really makes enterprises more quickly into a poor state of development, immortality is already the midst of sadness!From a development perspective, the prospects for the development of the LED lighting business is actually getting bigger, both at the technical level or at the economic level, we can foresee, however, very critical outdoor led light companies in order to find the way out, they must the To create the LED industry already has a certain industrial base, to solve the key technology R & D upstream is relatively weak, at the same time use of brand ideas come and re-operation of the enterprise, and the only way, businesses can keep their footing, and goes far. on the way may be the next big thing in LED industry.

LED s—So long as you live a better life than i

Currently, many LED companies, in order to get more profits in the fierce competition, their products in fact exist within a lot of problems. However the layman can not see   any transmission of the disease of their products. Teach you how to distinguish good led lights & led COB display products, it need to reach these kinds of standards.
LED display on the ambient temperature is very picky. Theoretically at a room temperature of 25 ℃, the best of their work status. But actually, the outdoor display in the application ambient temperature is quite complicated, summer maximum temperature may be above 60 ℃, the lowest temperature in winter may be -20 ℃ below. LED, IC efficiency and performance are inconsistent brightness inconsistent display screen body as a whole will naturally become spent. Under different temperature conditions, the red, green, and blue three lamp brightness decay and fall is different, at 25 ℃, the white balance is normal, but at 60 ℃, three-color outdoor led lights brightness declined, and the attenuation values do not match, it will produce the entire screen brightness down and cast the phenomenon, will decline in the quality of the entire screen. The internal display Other positive efforts to the large number of improvements in aspects of the design, process, and can effectively control the temperature of the external environment on the ultimate effect of the display, as much as possible of the LED display can be in a variety of complicated conditions perfect display.
Power supply also affects the quality of an important part of an  led lights display system. Power under different temperature conditions, the stability of their work, the output voltage value and with a load capacity will vary, because it is responsible for logistical role, its ability to protect the direct impact on the quality of the screen. Performance and stability, power supply prices of different brands and specifications are also considerable differences. Not just look at the low price without looking at the performance and quality to choose.
A well-known brands such as LED, is to go through the long-term market hard work to get recognized by the society. Enterprises depending on the brand for life and will never be easy for short-term interests and hurt their brand image.
