Description

A split LED light source

technical field

The invention relates to a split type LED light source.

Background technique

With the development of science and technology, LED solid-state lighting sources are widely used, and more and more of them are used as lighting sources. Existing LED light sources generally make the driver and the LED substrate into a structure that is not disassembled. Therefore, when the light source or a part of the driver is damaged, it is impossible to repair or replace some parts, and the entire light source can only be scrapped, which has caused a certain degree of damage. Waste, especially for high-power light sources, the cost is high, and the overall scrapping causes the use cost to be too high; in addition, the drive circuit of the existing LED light source is close to the heat sink, and the heat generated by the LED will affect the components of the drive circuit. For example, if the temperature is too high, the life of the capacitor will be shortened, resulting in a reduction in the life of the entire light source; in addition, for the existing lawn lights with the structure of R7s or RX7s lamp caps, due to the limitation of the housing space of the lamps, holding the light source in hand It is inconvenient to install and replace.

The technical solution adopted in the present invention is: the present invention includes a light source module and a driving module, and the light source module and the driving module are detachably connected in a split form.

The light source module includes a heat dissipation substrate with LEDs and a radiator. The heat dissipation substrate is in contact with the radiator and conducts heat dissipation. The drive module includes a drive circuit board assembly, a lower cover, and an upper cover. The lower cover is connected with the upper cover to form a box body and the drive circuit board assembly is placed in the box body. The upper cover leads out two electrode posts electrically connected to the output end of the drive circuit board assembly, and the two electrode pins are detachably plugged into the two electrode posts.

The heat sink is provided with two through holes for the electrode posts and the electrode pins to pass through.

The upper cover is provided with two hollow protrusions, and the two hollow protrusions cover the sides of the two electrode inserts.

The two electrode posts are electrically connected to the output end of the driving circuit board assembly through wires.

The light source module further includes two side cover plates, and the two side cover plates are fixedly connected to two sides of the heat sink by screws.

The light source module also includes a light-transmitting cover, which is plugged and fixed on the front of the heat sink and located in the light emitting direction of the LED.

The driving module further includes two connecting electrodes, and the two connecting electrodes are respectively located on two sides of the upper cover.

The distance between the two ends of the electrodes is between 68mm and 88mm, or between 108mm and 128mm, or between 179mm and 199mm, or between 244mm and 264mm.

The connecting electrode is an R7s or RX7s lamp base structure.

The beneficial effects of the present invention are: since the present invention includes a light source module and a drive module, the light source module and the drive module are detachably connected in a split type, when a part of the light source or drive is damaged, the damaged part of the module can be replaced accordingly, which is convenient Overhaul and maintenance do not need to scrap the entire light source, which saves the cost of use and avoids waste; in addition, the drive circuit and the radiator belong to two modules, and the isolation of the two can reduce the heat generated by the LED when it is working. The impact of the components can prolong the life of the light source; in addition, for lamps with a small internal space, the driver module can be installed first, and then the light source module, which is conducive to the operation of the hand in the housing and avoids the fact that the overall light source is too large for hands to operate. Blocking, so the present invention is easy to install, easy to maintain, heat has little influence on the driving element, and is beneficial to prolong the service life.
