Embodiment Construction

[0023] image 3 Show the projector 1 of the present invention, it includes a fan 2, and a light bulb assembly 100, it should be understood that in the projector 1, other components such as the light guide pipe 3 and the lens 4 are also provided, because it has nothing to do with the present invention. relationship, and its detailed drawings and descriptions are omitted here.

[0024] The light bulb assembly 100 is disposed near the fan 2 . like Figure 4a , 4b As shown, the bulb assembly 100 has a wind deflector 10 , a lamp holder 20 , and a bulb 30 . The lamp holder 20 has a bottom 21 and an opening 22 , and has an air inlet 23 on one side; the air inlet 23 is located near the fan 2 , and has a post 24 and a protrusion 25 on its upper and lower sides.

[0025] The bulb 30 has a wick 31 disposed on the bottom 21 of the lamp holder 20 and extending toward the opening 22 of the lamp holder 20 .

[0026] The air guide sheet 10 is disposed on the air inlet 23 of the lamp hold...

Abstract

This invention relates to projector with bulb elements and its wind conductor located in the projector, wherein, the bulb element has one socket and one bulb; the socket has one bottom and one opening part; the bulb has one lamp core located on the bottom extending to the opening part. The wind conductor comprises one body, one first flow conductor part, one-second-flow conductor and one-third-flow conductor part. The body is set on the socket and the first flow conductor part is integrated to the body part extending to the lamp core and bottom. The second flow conductor is integrated to the body extending to the lamp core. The third flow conductor is integrated to the body extending to the lamp core and opening part.

Description

technical field [0001] The invention relates to a projector, a light bulb assembly and its air guide sheet, in particular to an air guide sheet which can keep the light bulb assembly in operation and meet the working temperature specification. Background technique [0002] In the projector, one of the important functions of the heat dissipation system is to maintain the temperature of the lamp assembly within the normal working range, so as to ensure the life of the lamp assembly and prevent the lamp from bursting. Bulb components are generally provided by professional lamp factories, and the specifications and measurement methods of their operating temperature are also suggested by the lamp factory. When the projector system manufacturer designs the entire projector, the heat dissipation system must provide sufficient heat dissipation to maintain the lamp. When the components are in operation, they can meet the working temperature specifications of the lamp factory. [000...
