Description of the Invention: [Technical Field] The present invention relates to a fan, and more particularly to a fan equipped with a diode lamp. [Prior Art] θ With the rapid development of the sub-industry industry, such as the computer keyboard electronic components, the speed of operation has also increased dramatically. 'How to dissipate the heat of the electronic tree to protect its normal private, - the direct industry must Solve the problem. It is well known that the central processing unit installed on the motherboard is the core of the computer system, and when the computer is running, the central processing generates heat. Excessive heat can cause the central processor to fail to run. In order to effectively dissipate the heat generated by the central processing unit during operation, the heat generated by the __dispensing device is usually dissipated. The heat sink is mainly composed of a fan and a heat sink, wherein the fan is locked on the heat sink, and the heat sink is placed on the central processor, so that the heat generated by the central processing unit is discharged from the heat sink 1 '- aspect, another __ In terms of the fan operation, a powerful wind is blown to the radiator to continuously remove heat from the radiator, thereby preventing the central processor from overheating and reducing work efficiency and even damage. A conventional computer fan is completely enclosed by an opaque casing, and no fan is visible from the outside of the casing. Therefore, it is not difficult to see that traditional computers only focus on the pursuit of practicality. Recently, transparent panels of various patterns have been popular on the side of the computer casing, and the beautiful neon lights are transmitted from the inside of the casing, which is dazzling. This kind of colorful lighting effect is achieved by using a light-emitting diode (LED). The basic structure of the LED is an electronically illuminated semiconductor module packaged in an epoxy resin that acts as a positive and negative electrode through the pins and serves as a support. LEDs are characterized by small size, low power consumption, fast response, high performance, multiple colors, no radiation, and long life. LEDs can be placed on computer components such as fans, power supplies or graphics cards. The Chinese Patent Publication No. 2641353Y discloses a fan equipped with an LED lamp. The fan comprises a square outer frame, and a hole is formed on the outer side of the outer frame, and LED lights of various colors are arranged in the hole. However, since the fan of such a structure is provided with an LED lamp on the outer frame, it is necessary to open a hole in the outer frame, which is complicated and increases the complexity of the fan mold. In addition, LED light settings 6 1287348
