Abstract
The utility model discloses a high power direct plug-in light-emitting diode (LED) light source. The LED light source comprises an outer shell, a positive electrode pin, a negative electrode pin, an LED chip and a printed circuit board (PCB), a groove for placing the LED chip is arranged at the upper end of the positive electrode pin, the positive electrode pin and the negative electrode pin are respectively connected with the LED chip through a leading wire, the positive electrode pin and the negative electrode pin are connected with the PCB, the outer shell covers the upper ends of the positive electrode pin and the negative electrode pin and the LED chip, a gap is reserved between the outer shell bottom and the PCB upper surface, portions of the positive electrode pin and the negative electrode pin, which are located between the outer shell bottom and the PCB, the outer shell bottom and the PCB are packaged together through silica gel, accordingly heat generated by the LED chip can be dissipated through the silica gel, and the light loss caused by the overheat of the LED chip can be avoided.
Description
Technical field
The utility model relates to a kind of lighting device, particularly relates to a kind of high-power direct plug-in type led light source.
Background technology
The high-power direct plug-in type led light source comprises a shell, anodal pin, negative pole pin, led chip, a pcb board, and said led chip is arranged in the groove on anodal pin top, and said anodal pin is connected with pcb board with the negative pole pin.In the traditional design, the bottom surface of shell directly contacts with pcb board, and such design makes that the heat radiation of whole LED light source is very poor.
The utility model content
The purpose of the utility model is to overcome the deficiency of present technology, provides a kind of heat dispersion good high-power direct plug-in type led light source.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of high-power direct plug-in type led light source; Comprise a shell, anodal pin, negative pole pin, led chip, pcb board; Said anodal pin upper end is provided with one and supplies the groove of led chip placement; Said anodal pin and negative pole pin are connected with led chip through lead-in wire respectively, and said anodal pin is connected with pcb board with the negative pole pin, and said shell covers in the upper end and the led chip of anodal pin, negative pole pin in it; Have the gap between said outer casing bottom and the pcb board upper surface, said outer casing bottom, pcb board and the anodal pin between outer casing bottom and pcb board, negative pole pin part are packaged together through silica gel.
The beneficial effect of the utility model is: have the gap between said outer casing bottom and the pcb board upper surface; Said outer casing bottom, pcb board and the anodal pin between outer casing bottom and pcb board, negative pole pin part are packaged together through silica gel; So; The heat that led chip produces can distribute through silica gel, can avoid the overheated light loss that causes of led chip, that is to say the utility model high-power direct plug-in type led light source perfect heat-dissipating.
Description of drawings
Fig. 1 is the sketch map of the utility model high-power direct plug-in type led light source.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1; The utility model high-power direct plug-in type led light source comprises a shell 1, anodal pin 2, negative pole pin 3, led chip 4, pcb board 5; Said anodal pin 2 upper ends are provided with one and supply the groove 21 of led chip 4 placements; Said anodal pin 2 and negative pole pin 3 are connected with led chip 4 through lead-in wire 6 respectively, and said anodal pin 2 is connected with pcb board 5 with negative pole pin 3, and said shell 1 covers in the upper end and the led chip 4 of anodal pin 2, negative pole pin 3 in it.
In the present embodiment; Preferably; Have the gap between said shell 1 bottom and pcb board 5 upper surfaces; Said shell 1 bottom, pcb board 5 and the anodal pin 2 between shell 1 bottom and pcb board 5, negative pole pin 3 parts are packaged together through silica gel 7 (shown in Fig. 1 oblique stroke), and so, the heat that led chip 4 produces can distribute through silica gel 7; Can avoid the led chip 4 overheated light losses that cause, that is to say the utility model high-power direct plug-in type led light source perfect heat-dissipating.
