Description

Technical Field

[0001] The utility model relates to an LED light source, in particular to an LED light source with an electrically polarized substrate and an insulating mounting component thereof. Background Art

[0002] Currently, LED light sources are widely used in various lighting devices. Among them, one type of LED light source needs to be insulated from the heat sink during installation due to the electrical polarity of its mounting substrate. Figure 1 The figure shows a schematic diagram of a traditional LED light source installation with an electrical polarity mounting substrate. An insulating thermal pad 4 is placed between the substrate 2 of the LED light source 1 and the heat sink 3, ensuring that the LED light source 1 is both heat-dissipating and insulated from the heat sink 3. The substrate 2 and heat sink 5 are secured together with screws 5, which are separated from the substrate 2 of the LED light source 1 by a T-shaped plastic pad 6 to ensure insulation. With this method, if the hole in the LED light source substrate is relatively small, there won't be a suitable T-shaped plastic washer available. Furthermore, due to the limited hole size of the LED light source, the wall thickness of the T-shaped plastic washer cannot be made too thin. In this case, the traditional assembly method is unsuitable. Utility Model Content

[0003] In response to the above technical problems, the utility model discloses an LED light source with an electrically polarized substrate and an insulating mounting component thereof, which is insulated and fixed to a heat sink through an insulating mounting piece, has a simple structure and is easy to implement.

[0006] With this technical solution, the substrate can be fixed to the nut inside the insulating part by screws, which plays a role of fixing and insulation, solving the installation problem when the traditional mounting substrate has a small assembly hole for the polarity LED light source and the T-shaped plastic ring cannot be used.

[0008] As a further improvement of the present invention, the groove is located in the middle of the side wall of the nut, and the stripes are located on the upper and lower sides of the side wall of the nut.

[0009] As a further improvement of the present invention, the top of the embedded nut is lower than the top of the insulating member, and the top of the insulating member is provided with a fixing groove for convenient fixation.

[0010] As a further improvement of the present invention, the fixing groove is in a straight line shape.

[0011] As a further improvement of the present invention, the mounting hole is a blind hole.

[0012] As a further improvement of the present invention, the insulating member is injection molded on the outer surface of the nut.

[0013] As a further improvement of the present invention, the nut is made of metal, and the insulating member is made of nylon, ABS, POM, PC, PPS, PBT or PPO. Further preferably, the insulating member is made of high-temperature resistant plastic.
