Description
- The present disclosure relates to a dust removal system, and more particularly, to a dust removal system for cleaning LED (light emitting diode) strips and an apparatus with the dust removal system.
- LEDs have many advantages, such as high luminosity, low operational voltage, low power consumption, compatibility with integrated circuits, easy driving, long term reliability, and environmental friendliness. Such advantages have promoted the wide use of LEDs as a light source. Nowadays, LED strips are commonly applied in lamps. Generally, the LEDs of the LED strips are encapsulated by resin. However, dust may be adhered on the outer surfaces of the resin encapsulants of the LEDs. As a result, the brightness as well as the appearance of the LED strips are unfavorably affected by the dust.
- What is needed, therefore, is a dust removal system for an LED strip and apparatus with the dust removal system which can overcome the described limitations.
- Many aspects of the present disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the views.
-
FIG. 1 is a schematic view of an apparatus with a dust removal system in accordance with an embodiment of the present disclosure. -
FIG. 2 is a schematic view of a structure of the dust removal system of the apparatus shown inFIG. 1 . - Referring to
FIG. 1 , anapparatus 100 with adust removal system 30 for anLED strip 70 in accordance with an embodiment of the present disclosure is shown. Theapparatus 100 includes anoperating zone 10 and atransporting belt 20 extending through theoperating zone 10. Theoperating zone 10 includes awarming zone 40, ahigh temperature zone 50 and acooling zone 60. Thedust removal system 30 is located in thewarming zone 40. Thetransporting belt 20 moves along a direction “a” shown inFIG. 1 . TheLED strip 70 with a plurality ofLEDs 71 mounted thereon is disposed on thetransporting belt 20. TheLED strip 70 is transported by thetransporting belt 20 to sequentially pass thewarming zone 40, thehigh temperature zone 50 and thecooling zone 60 and leave theapparatus 100. Temperature of thewarming zone 40 is lower than 100° C. . - The
high temperature zone 50 can provide a temperature higher than 200° C., so that theLED strip 70 can be reflowed in thehigh temperature zone 50. - Referring to
FIG. 2 , thedust removal system 30 includes an upperairflow generating device 301 and a lowerairflow generating device 302. Thetransporting belt 20 passes through a middle of thedust removal system 30, between the upperairflow generating device 301 and the lowerairflow generating device 302. The upperairflow generating device 301 includes a blowingport 31 which blows air to thetransporting belt 20. That is to say, the blowingport 31 faces downwardly. The upperairflow generating device 301 includes an electrostatic eliminatingbar 311 located at a middle of a bottom end of the blowingport 31. The electrostatic eliminatingbar 311 can be fastened to a top plate or side plates of the blowingport 31. A cross-sectional dimension of the electrostatic eliminatingbar 311 is smaller than that of the blowingport 31. Thus, the electrostatic eliminatingbar 311 will not block the blowingport 31 from blowing air to thetransporting belt 20. The upperairflow generating device 301 includes abrush 312 near the bottom end of the blowingport 31. The lowerairflow generating device 302 includes asucking port 32 corresponding to the blowingport 31 of the upperairflow generating device 301, which sucks air from thetransporting belt 20. The lowerairflow generating device 302 includes an electrostatic eliminatingbar 321 located at a middle of a top end of thesucking port 32. The lowerairflow generating device 302 includes abrush 322 near the top end of thesucking port 32. Preferably, thedust removal system 30 will not extend to thehigh temperature zone 50 in order to avoid damage to the upperairflow generating device 301 and the lowerairflow generating device 302 under a high temperature environment. Furthermore, the separation of thedust removal system 30 and thehigh temperature zone 50 can protect thehigh temperature zone 50 from being affected by air flow produced by the upperairflow generating device 301 and the lowerairflow generating device 302. - The
LED strip 70 enters theoperating zone 10 by thetransporting belt 20 and arrives at thedust removal system 30 in thewarming zone 40. Due to heating of thewarming zone 40 to theLED strip 70, theLED strip 70 is dried. After that theLED strip 70 has been warmed and dried in thewarming zone 40, adhesion force of the dust on theLED strip 70 becomes poor. The blowingport 31 can easily blow dust away from theLED strip 70. At the same time, thesucking port 32 sucks the dust blown by the blowingport 31 to leave theoperating zone 10. Therefore, dust attached on theLED strip 70 is cleaned. In the process of theLED strip 70 passing through thedust removal system 70, the electrostatic eliminatingbars LED strip 70 in order to avoid electrostatic from absorbing dust. Thebrushes port 31 and the suckingport 32 disturb the air flow from the blowingport 31 to the suckingport 32, to enable the dust to more easily float around from the outer surfaces of the encapsulants covering LED chips of theLEDs 71 to thereby obtain a better dust removal effect. - The
dust removal system 30 is not limited to include only oneair blowing port 31 and only one suckingport 32. A plurality ofair blowing ports 31 andair sucking ports 32 may be used according to a length of theLED strip 70. Alternatively, each blowingport 31 may match withseveral sucking ports 32, or each suckingport 32 may match with severalblowing ports 31. Furthermore, thedust removal system 30 can include only one of the blowingport 31 and suckingport 32 if only one of the blowingport 31 and suckingport 32 can provide sufficient air flow for cleaning the dust from theLED strip 70. However, thesucking port 32 is preferable since thesucking port 32 can provide a chamber to collect the drawn dust. - Alternatively, the
brushes brushes brush 312 can directly brush a top surface of theLED strip 70 and thebrush 322 can directly brush a bottom surface of theLED strip 70. As a result, the dust on theLED strip 70 can be cleaned more easily. - It is believed that the present disclosure and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the present disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments.
