技术领域
本实用新型涉及灯具技术，具体涉及一种可产生动态光效的艺术吊灯。
背景技术
目前，现有的吊灯，一般是采用在透明或半透明材质制成的灯罩内，放置电灯泡、节能灯管或其它光源，使光线柔和的投射出来，形成一种温和、宁静、朦胧、浪漫的氛围。为了使其更具艺术性、观赏性，在灯罩上镀膜或设置图案，并且往往还在灯罩上设置若干镂空的图案或花纹。但是，这些图案或花纹，都只是静态的。
目前，基于LED技术的电子蜡烛等新型节能光源已经得到越来越广泛的应用，但是，其并没有在吊灯等制品中得到相应的运用，特别是LED可发出多种色光，并且环保、安全、节能，完全可以代替传统灯具，并且能够产生较好的艺术效果。
但是，由于单体LED发出的色光波长较短，其直接穿过灯罩时，所投射出来的光线效果比较单调，并缺乏动感，艺术感染力较弱。

Computer Viruses

What are computer viruses?
According to Fred Cohen’s well-known definition, a computer virus is a computer program that can infect other computer programs by modifying them in such a way as to include a (possibly evolved) copy of itself. Note that a program does not have to perform outright damage (such as deleting or corrupting files) in order to be called a “virus”. However, Cohen uses the terms within his definition (e.g. “program” and “modify”) a bit differently from the way most anti-virus researchers use them, and classifies as viruses some things which most of us would not consider viruses.
Computer viruses are bits of code that damage or erase information, files, or software programs in your computer, much like viruses that infect humans, computer viruses can spread, and your computer can catch a virus when you download an infected file from the Internet or copy an infected file from a diskette. Once the viruses is embedded into your computer’s files, it can immediately start to damage or destroy information, or it can wait for a particular date or event to trigger its activity.
What are the main types of viruses?
Generally, there are two main classes of viruses. The first class consists of the file Infectors which attach themselves to ordinary program files. These usually infect arbitrary .COM and/or .EXE programs, though some can infect any program for which execution is requested, such as .SYS,.OVL,.PRG,&.MNU files.
File infectors can be either direct action or resident. A direct-action virus selects one or more other programs to infect each other time the program which contains it is executed ,and thereafter infects other programs when “they” are executed (as in the case of the Jerusalem) or when certain other conditions are fulfilled. The Vienna is an example of a direct-action virus. Most other viruses are resident.
The second class is system or boot-record infectors: those viruses, which infect executable code, found in certain system areas on a disk that are not ordinary files. On DOS systems, there are ordinary boot-sector viruses, which infect only the DOS boot sector on diskettes. Examples include Brain, Stoned, Empire, Azusa, and Michelangelo. Such viruses are always resident viruses.
Finally, a few viruses are able to infect both (the Tequila virus is one example). There are often called “multipartite” viruses, though there has been criticism of this name; another name is “boot-and -file” virus.
File system or cluster viruses (e.g. Dir-II) are those that modify directory table entries so that the virus is loaded and executed before the desired program is. Note that the program itself is not physically altered; only the directory entry is. Some consider these infectors to be a third category of viruses, while others consider them to be a sub-category of the file infectors.
What are macro viruses?
Many applications provide the functionality to create macros. A macro is a series of commands to perform some application-specific task. Macros are designed to make life easier, for example, to perform some everyday tasks like text-formatting or spreadsheet calculations.
Macros can be saved as a series of keystrokes (the application record what keys you press); or they can be written in special macro languages (usually based on real programming languages like C and BASIC). Modern applications combine both approaches; and their advanced macro languages are as complex as general purpose programming languages. When the macro language allows files to be modified, it becomes possible to create macros that copy themselves from one file to another. Such self-replicating macros are called macro viruses.
Most macro viruses run under Word for Windows. Since this is a very popular word processor, it provides an effective means for viruses to spread. Most macro viruses are written using the macro language WordBasic. WordBasic is based on the good old BASIC programming language. However, it has many (hundreds of) extensions (for example, to deal with documents: edit, replace string, obtain the name of the current document, open new window, move cursor, etc.).
What is a Trojan horse program?
A type of program that is often confused with viruses is a ‘Trojan horse’ program. This is not a virus, but simply a program (often harmful) that pretends to be something else.
For example, you might download what you think is a new game; but when you run it, it deletes files on your hard drive. Or the third time you start the game, the program E-mail your saved passwords to another person.
Note: simply download a file to your computer won’t activate a virus or Trojan horse; you have to execute the code in the file to trigger it. This could mean running a program file, or opening a Word/Excel document in a program (such as Word or Excel) that can execute any macros in the document.
What kind of files can spread viruses?
Viruses have the potential to infect any type of executable code, not just the files that are commonly called “program files”. For example, some viruses infect executable code in the boot sector of floppy disk or in system areas of hard drives. Another type of virus, known as a “macro” virus, can infect word processing and spreadsheet documents that use macros. And it’s possible for HTML documents containing JavaScript or other types of executable code to spread viruses or other malicious code.
Since viruses code must be executed to have any effect, files that the computer treats as pure data are safe. This includes graphics and sound files such as .gif, .jpg, .mp3, .wav, .etc., as well as plain text in .txt files. For example, just viewing picture files won’t infect your computer with a virus. The virus code has to be in a form, such as an .exe program file or a Word .doc file which the computer will actually try to execute
How do viruses spread?
The methodology of virus infection was pretty straightforward when first computer viruses such as Lehigh and Jerusalem started appearing. A virus is a small piece of computer code, usually form several bytes to a few tens of bytes, that can do, well, something unexpected. Such viruses attach themselves to executable files— programs, so that the infected program, before proceeding with whatever tasks it is supposed to do, calls the virus code. One of the simplest ways to accomplish that is to append the virus code to the end of the file, and insert a command to the beginning of the program file that would jump right to the beginning of the virus code. After the virus is finished, it jumps back to the point of origination in the program. Such viruses were very popular in the late eighties. The earlier ones only knew how to attach themselves to .Com files, since structure of a .COM file is much simpler than that of an .EXE file—yet another executable file format invented for MS-DOS operating system. The first virus to be closely studied was the Lehigh virus. It attached itself to the file that was loaded by the system at boot time—COMMAND.COM. the virus did a lot of damage to its host, so after three-four replications it was no longer usable. For that reason, the virus never managed to escape the university network.
When you execute program code that’s infected by a virus, the virus code will also run and try to infect other programs, either on the same computer or on other computers connected to it over a network. And the newly infected programs will try to infect yet more programs.
When you share a copy of an infected file with other computer users, running the file may also infect their computer; and files from those computers may spread the infection to yet more computers.
If your computer if infected with a boot sector virus, the virus tries to write copies of itself to the system areas of floppy disks and hard disks. Then the infected floppy disks may infect other computers that boot from them, and the virus copy on the hard disk will try to infect still more floppies.
Some viruses, known as ‘multipartite’ viruses, and spread both by infecting files and by infecting the boot areas of floppy disks.
What do viruses do to computers?
Viruses are software programs, and they can do the same things as any other program running on a computer. The accrual effect of any particular virus depends on how it was programmed by the person who wrote the virus.
Some viruses are deliberately designed to damage files or otherwise interfere with your computer’s operation, while other don’t do anything but try to spread themselves around But even the ones that just spread themselves are harmful, since they damage files and may cause other problems in the process of spreading.
Note that viruses can’t do any damage to hardware: they won’t melt down your CPU, burn out your hard drive, cause your monitor to explode, etc. warnings about viruses that will physically destroy your computer are usually hoaxes, not legitimate virus warnings.
Modern viruses can exist on any system form MS DOS and Window 3.1 to MacOS, UNIX, OS/2, Windows NT. Some are harmless, though hard to catch. They can play a jingle on Christmas or reboot your computer occasionally. Other are more dangerous. They can delete or corrupt your files, format hard drives, or do something of that sort. There are some deadly ones that can spread over networks with or without a host, transmit sensitive information over the network to a third party, or even mess with financial data on-line.
What’s the story on viruses and E-mail?
You can’t get a virus just by reading a plain-text E-mail message or Usenet post. What you have to watch out for are encoded message containing embedded executable code (i.e., JavaScript in HTML message) or message that include an executable file attachment (i.e., an encoded program file or a Word document containing macros).
In order to activate a virus or Trojan horse program, you computer has to execute some type of code .This could be a program attached to an E-mail, a Word document you downloaded from the Internet, or something received on a floppy disk. There’s no special hazard in files attached to Usenet posts or E-mail messages: they’re no more dangerous than any other file.
What can I do to reduce the chance of getting viruses from E-mail？
Treat any file attachments that might contain executable code as carefully as you would any other new files: save the attachment to disk and then check it with an up-to-date virus scanner before opening the file.
If you E-mail or news software has the ability to automatically execute JavaScript, Word macros, or other executable code contained in or attached to a mes
