High Power LED Lamp

technical field

The invention relates to a lighting fixture, in particular to a high-efficiency, super-brightness high-power LED lamp.

Background technique

Traditional incandescent or fluorescent lamps consume a lot of power, have a short service life, pollute the environment, and are easily damaged. LED is a semiconductor solid-state light-emitting device, which consumes less power, has a long service life, is environmentally friendly, and is not easily damaged. The promotion of LED lights can save a lot of power and reduce lighting costs.

Contents of the invention

The technical problem to be solved by the present invention is to provide a high-power LED lamp with low power consumption, long service life, environmental protection, high efficiency and super brightness.

In order to solve the above technical problems, the technical solution of the present invention is: a high-efficiency, super-brightness high-power LED lamp, the lamp base and the insulating plate connected to it are positioned and installed on the top of the lamp body, and there are connecting lamps around the lamp body. The heat sink of the lamp body is installed on the lower end of the bottom plate of the lamp body with a heat-conducting insulating sheet and a reflective plate with a heat-conducting insulating sheet attached. Each group is installed in the insulating slot after being connected in parallel; the lamp holder is provided with a constant current drive circuit board. N light-emitting chips are connected in series to form a group, and M groups are packaged into a module at the same time, and the module is installed in the slot. The lamp holder is provided with a constant current drive circuit board. The bottom plate of the lamp body is square, rectangular, rhombus, triangle, circle or ellipse.

The beneficial effects of the present invention are:

1. The power consumption of LED lamps with the same brightness is only one-tenth of that of incandescent lamps, and the service life is as high as 100,000 hours. The promotion and use can save a lot of power and reduce lighting costs.

2. LED lights have small size, high efficiency, super brightness, good thermal conductivity, high reflective efficiency, high mechanical strength, not easy to damage, low maintenance cost, convenient replacement of LEDs, green and environmental protection, and can be made into various power and corresponding dimensions lights.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Embodiment 1 is shown in Figures 1-4 and 6-7: a high-efficiency, super-brightness high-power LED lamp body with a rectangular high-power LED lamp at the bottom, and the lamp holder 4 and the insulating rubber plate 3 are bonded with epoxy resin Integrate, and connect with the top of lamp body 1 by screw. The lamp holder 4 adopts a screw socket or socket common to traditional incandescent lamps, and a constant current source circuit board 12 is housed in the lamp holder 4, and two power supply leads are welded out to pass through the insulating rubber plate 3 and connect with the light-emitting diode LED or white light LED5 connected in series. The hollow cylinder of the lamp body 1 is integrated with the vertical radial fins 2 around it and the rectangular bottom plate. Its material is aluminum alloy with good thermal conductivity, light weight and low price. The size is determined according to the power of the LED. When working, the bottom plate heats up, the bottom of the heat sink is hot and the top is cold, and there is a temperature difference, which makes the hot air flow rise, and the rising air flow in the gap of the heat sink takes away the heat; the vertical radial heat sink 2 has a large heat dissipation area, and the efficiency of 360-degree uniform heat dissipation high. The surface treatment of the lamp body 1 doubles as a shell, which is beautiful and durable, and reduces the cost.
