Description

Technical Field

[0001] This application relates to the field of LEDs, and in particular to an LED lamp and its collection device. Background Art

[0002] LEDs can directly convert electricity into light and are solid-state semiconductor devices that can convert electrical energy into visible light. The lifespan of an LED can reach over 50,000 hours, which is more than 50 times that of a traditional tungsten filament lamp. Moreover, the energy consumption of white LEDs is only 1 / 10 of that of incandescent lamps and 1 / 4 of that of energy-saving lamps. In the future, as long as the cost of LED lamps decreases with the continuous improvement of LED technology, energy-saving lamps and incandescent lamps will inevitably be replaced by LED lamps.

[0003] LEDs are used for indoor home lighting, vehicle body lighting, street lighting, etc. The heat dissipation of LED lamps is relatively poor. Usually, LED lamp beads are installed on a heat sink with heat dissipation function to ensure the normal heat dissipation of the LED lamp. However, when used for vehicle lamps, the space occupied by the heat sink is relatively high, which affects the space utilization rate of the vehicle body, resulting in the inability to use a larger heat sink. Therefore, the heat dissipation effect of the LED lamp is not good and needs further improvement. Summary of the Invention

[0004] In order to improve the heat dissipation effect of LED lamps, this application provides an LED lamp and its collection device.

[0005] In a first aspect, an LED lamp provided by this application adopts the following technical solution:

[0006] An LED lamp includes a lamp cup. A wafer is provided on the bottom of the lamp cup. Two conductive sheets penetrate through the bottom of the lamp cup. A heat dissipation through groove is opened along the length direction at the bottom of the lamp cup. A heat dissipation opening located in the heat dissipation through groove is opened at the lower end of the conductive sheet.

[0007] By adopting the above technical solution, the wafer generates more heat during operation. The heat is better dissipated through the heat dissipation through groove. The heat on the wafer can also be transferred to the heat dissipation through groove through the conductive sheet. The heat dissipation holes opened on the conductive sheet facilitate the circulation of air in the heat dissipation through groove, which is more conducive to heat dissipation, thus effectively improving the heat dissipation effect of the LED lamp.

[0008] In a specific implementable manner, the inner walls at both ends of the lamp cup along the length direction are inclined. Heat dissipation grooves are opened at both ends of the lamp cup along the length direction. The heat dissipation grooves communicate with the heat dissipation through groove.

[0009] By adopting the above technical solution, the heat dissipation grooves further reduce the distance between the wafer and the outside air, and air can flow through the heat dissipation grooves, enhancing the heat dissipation effect of the side wall of the lamp cup and further improving the heat dissipation effect of the LED lamp.

[0010] In a second aspect, the present application discloses a collecting device for LED lamps, including a frame, on which a feeding mechanism, a detection and positioning mechanism, a tape mechanism and a collecting mechanism are provided. The tape mechanism is used for conveying a collecting tape, and the detection and positioning mechanism is used for electrically detecting and positioning the LED lamps.

[0011] By adopting the above technical solutions, the LED lamps are screened by the feeding mechanism, their performance is detected by the detection and positioning mechanism, they are conveyed and collected by the tape mechanism, and the collecting mechanism winds up the collecting tape, thereby completing the winding process of the LED lamps.

The width of the screening channel is greater than half of the length in the width direction of the lamp cup and less than half of the length in the length direction of the lamp cup. A feeding channel is also provided on the feeding tray.

[0013] By adopting the above technical solutions, the lamp cup enters the feeding channel through the screening channel. On the screening channel, only when the length direction of the lamp cup is the same as the length direction of the screening channel can the lamp cup be sent into the feeding channel, thereby completing the preliminary screening process.

A turntable is provided on the mounting frame, the axis of the turntable is arranged vertically, and a plurality of suction nozzles are provided on the bottom surface of the turntable. The detection and positioning mechanism further includes a positioning component, a performance detection component and a separation component provided below the turntable.

[0015] By adopting the above technical solutions, the lifting cylinder drives the mounting frame to lift vertically, and the turntable can rotate. When the suction nozzles on the turntable are close to one end of the feeding channel, the suction nozzles suck up the LED lamps, and then the lifting cylinder drives the turntable to rise. The LED lamps are sent to the positioning component for positioning. During the repeated processes of lifting and rotating, the LED lamps are placed on the performance detection component for electrical detection, and the unqualified ones are recycled through the separation component.

[0016] In a specific implementable embodiment, the positioning component includes a positioning box provided on the frame, and the side walls of the positioning box are inclined outward from the bottom of the box towards the box opening.

[0017] By adopting the above technical solutions, the LED lamps are placed into the positioning box, thereby correcting the orientation of the LED lamps, so that when the LED lamps are placed on the inspection table, the conductive sheets and the wires can be connected.

[0018] In a specific implementable embodiment, the performance detection component includes a detection table, on which a detection electric piece is provided, and the detection electric piece is electrically connected to a controller.

[0019] By adopting the above technical solution, the LED lamp is placed on the detection table, the detection electric piece is connected to the conductive piece of the LED lamp, and the electrical property of the LED lamp is detected after being powered on.

[0020] In a specific implementable embodiment, the separation component includes a separation tube provided on the frame, and an air nozzle located at the port of the separation tube is also provided on the frame.

[0021] By adopting the above technical solution, the unqualified LED lamps are sprayed into the separation tube by the air nozzle, so as to achieve the screening effect.

Detailed implementation manners

[0037] The following Figures 1-7 further elaborates on the present application in detail.

[0038] An embodiment of the present application discloses an LED lamp. Referring to Figure 1 and Figure 2 , an LED lamp includes a lamp cup 1. A heat dissipation through groove 11 is provided at the bottom of the lamp cup 1. The side walls at both ends in the length direction of the lamp cup 1 are inclined, and the inclined side walls facilitate the reflection of light. Heat dissipation grooves 12 are provided at both ends in the length direction of the lamp cup 1. The heat dissipation grooves 12 communicate with the heat dissipation through groove 11. The heat dissipation grooves 12 and the heat dissipation through groove 11 increase the contact area between the side wall and the bottom wall of the lamp cup 1 and the air, and are conducive to the circulation of air, greatly enhancing the heat dissipation efficiency of the LED lamp.

[0039] Referring to Figure 1 andFigure 2 On the bottom wall of the lamp cup 1, there is a chip 13. The chip 13 is connected to the bottom wall of the lamp cup 1 through die bonding glue. Two conductive sheets 14 are also penetrated through the bottom wall of the lamp cup 1. The two conductive sheets 14 are respectively located at both ends of the chip 13. The upper end of the conductive sheet 14 is attached to the chip 13, and the lower end of the conductive sheet 14 is located in the heat dissipation through groove 11. The heat generated on the chip 13 can also be introduced into the heat dissipation through groove 11 through the conductive sheet 14, thereby further enhancing the heat dissipation effect of the LED lamp. A heat dissipation opening 15 is formed at one end of the conductive sheet 14 located in the heat dissipation through groove 11, so that the heat dissipation through groove 11 is in a state of being communicated at both ends, which is beneficial to the air circulation in the heat dissipation through groove 11 and further improves the heat dissipation effect.

[0040] The implementation principle of an LED lamp in an embodiment of the present application is as follows: The chip 13 conducts electricity through the conductive sheet 14. The settings of the heat dissipation through groove 11 and the heat dissipation groove 12 increase the contact area between the lamp cup 1 and the air, thereby improving the heat dissipation effect. One end of the conductive sheet 14 is located in the heat dissipation through groove 11, and the conductive sheet 14 is beneficial to the heat dissipation of the chip 13, further improving the heat dissipation effect of the LED lamp.

[0041] The embodiment of the present application also discloses a collection device for an LED lamp. Refer to Figure 3 After the LED lamp is produced, it is collected through the receiving tape 2.

A screening block 45 is also provided on the screening channel 44. The top surface of the screening block 45 is set as an inclined surface. When the heat dissipation through groove 11 of the lamp cup 1 is downward, when the lamp cup 1 moves, the screening block 45 passes through the heat dissipation through groove 11. When the heat dissipation through groove 11 of the lamp cup 1 is upward, under the action of the screening block 45, the lamp cup 1 will fall back into the loading tray 41 again.
