Description

An embedded waterproof LED lamp

technical field

The utility model The utility model relates to a semiconductor lighting lamp, in particular to an embedded waterproof LED lamp using single or multiple high-power light-emitting diodes (LEDs) as light sources.

Background technique

With the rapid development of the economy, the construction of modern cities is changing with each passing day, and the vitality of the city is constantly improving. Many cities have implemented lighting projects to brighten the bustling commercial blocks, shopping malls, high-rise buildings, public places, and city signs. Sexual buildings, etc., all depend on installing high-power LED lamps outdoors or burying them on the ground to irradiate them to achieve the effect of beautifying the city. However, this kind of high-power LED lamp needs to be connected with a driver to support its normal operation. At present, the commonly used high-power LED lamps use an external driver to connect to the LED lamp to achieve work, but the driver is exposed to the sun and rain. Aging can also easily lead to unstable performance of the drive circuit, which brings inconvenience to the installation and affects the appearance of the product. In order to overcome the shortcomings caused by the external driver, some manufacturers have designed a driver that is placed in the cavity of the lamp body. High-power LED lamps are sealed to the lamp body after leading out the wires. Although this design overcomes the shortcomings of the external driver, it also has some shortcomings. First, the driver and the high-power LED lamp are in the same chamber; the LED emits light The high temperature generated at the time will affect the stability of the driver, followed by the addition of a driver in the lamp body; the height of the lamp will be increased; the production cost will be increased invisibly, and the second is that the driver cannot be installed and fixed in the cavity; it is easy Cause the connection parts to loosen or even fall off, affecting the normal operation of the product.

Contents of the invention

Aiming at the defects of the above-mentioned embedded waterproof LED lamps, the utility model provides an embedded waterproof LED lamp that is neither externally connected nor placed in the lamp body chamber, and is beautiful, stable, long in service life and low in cost. .

In order to achieve the above purpose, the embedded waterproof LED lamp designed by the utility model includes a tubular metal lamp holder, an LED lamp installed in the metal lamp holder, and a wire connected to the LED lamp and the driver. The LED lamp is fixed on On the surface of a heat sink, the front end of the metal lamp holder is provided with a piece of transparent glass that completely covers the port, and a circle of table edges for placing heat sinks is horizontally arranged around the tube wall in the metal lamp holder. A driver electrically connected to the lead wire of the LED lamp is placed at the rear end of the inner heat sink, and a waterproof adhesive layer is provided to completely bury the driver, and the waterproof adhesive layer is completely bonded to the inner tube wall of the metal lamp holder.

The preferred technical scheme of the utility model is:

The LED lamp is a single or multiple high-power LEDs, and a bracket for installing a lens is connected with a screw on the heat sink surface, and a pit is provided at the bottom of the lens, and the single or multiple high-power LEDs are It is installed in the cavity of the lens.

The waterproof adhesive layer is an epoxy resin adhesive layer.

The lens may be a direct lens or an astigmatism lens.

The heat sink is an aluminum heat sink.

The heat sink is placed on the edge of the tube lumen platform of the metal lamp base.

Since the front end of the metal lamp holder of the utility model is sealed with light-transmitting glass, and the driver is buried in a layer of epoxy resin adhesive layer poured backwards from the back end of the heat sink in the metal lamp holder, this solves the problem caused by the external driver. Inconvenience and to avoid the defects in the same chamber with high-power LED lamps, the driver and epoxy resin are skillfully integrated into one, and completely bonded with the inner tube wall of the metal lamp holder to form a waterproof adhesive layer, so that both The space is saved, the stability of the product is improved, and the production cost is virtually saved, and the structure is simple, compact and beautiful.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Fig. 1 and Fig. 2; the metal lamp holder 3 of the present utility model is tubular, on the inner wall of the front end of the metal lamp holder 3, a light-transmitting glass sheet 1 that completely covers the port is fixed with glue (also can be used) Screws are used to press and seal the light-transmitting glass sheet and the rubber ring provided on the front end of the metal lamp holder), and a circle of platform edges for placing heat sinks 7 is horizontally arranged around the inner tube wall at the middle and lower part of the metal lamp holder 3 30. A high-power LED lamp 6 is fixed on the surface of the heat sink 7 by bonding or screwing. The heat sink 7 is made of aluminum material with good heat dissipation; Placement, screw 8 on the heat sink 7 is also connected with a bracket 4 with lens 5, the bottom of the lens 5 is provided with a pit, the single high-power LED lamp 6, (or multiple high-power LED Light) is just installed in the pit of lens 5, and lens 5 can be changed into direct-light lens or astigmatism lens according to the needs of use, will be installed with single high-power LED lamp 6 (or multiple high-power LED lamps) and be installed with lens 5 and the heat sink 7 side of the bracket 4 enter from the back port of the metal lamp holder 3 until the heat sink 7 reaches the table edge 30 provided for it to block it, and then place a driver 9 electrically connected to the wire of the high-power LED lamp 6 On the rear end surface of the heat sink 7, lead the wire electrically connected to the driver 9 from the rear port of the metal lamp holder 3, and finally use the rear end surface of the heat sink 7 as a baffle to pour a layer of epoxy resin glue that completely bury the driver 9 10. This layer of epoxy resin glue 10 is completely bonded to the inner tube wall of the metal lamp holder 3. After the layer of epoxy resin glue 10 is solidified, a waterproof glue layer is formed, and the driver 9 and epoxy resin glue 10 are skillfully fused into a The integrated structure not only saves space, but also improves the stability of the product, and virtually saves production costs. Its structure is simple, compact and beautiful. With such a design, the entire embedded waterproof LED lamp is completely sealed, and it can be used after being installed outdoors or buried on the ground and connected to a power supply.
