Abstract
The utility model discloses an LED projection lamp, which comprises a casing and an LED light source assembly installed inside the casing. The casing comprises a die-casting aluminium upper casing and a die-casting aluminium lower casing. Cooling fins which are integrally molded with the die-casting aluminium lower casing are evenly distributed on the bottom surface of the die-casting aluminium lower casing. A power supply box which is used for placing a power supply assembly connected on a three-core power line is provided inside the die-casting aluminium lower casing. The power supply assembly is electrically connected with the LED light source assembly on the other surface of the die-casting aluminium lower casing. A lens assembly and a glass panel are layeredly distributed between the LED light source assembly and the die-casting aluminium upper casing. The LED projection lamp provided by the utility model has the advantages of convenient installation, good cooling effect, good light-emitting effect and long service life.
Description
Technical field
The utility model relates to the LED technical field of semiconductor illumination, is specifically related to a kind of LED Projecting Lamp.
Background technology
The led light source assembly is owing to have environmental protection and energy saving, brightness are high, the life-span is long and luminous efficiency is high characteristics and replaced ordinary light source gradually and be applied in lighting field.The LED Projecting Lamp is a kind of light fixture that is usually used in the places of need throwing light on such as various large-scale operations, job site, engineering machinery and Landscape Lighting on a large scale.LED Projecting Lamp light source in the market is conventional lighting sources simply to be replaced to LED form basically.In the prior art, two key factors that influence the LED Projecting Lamp life-span are: 1, lamp body shell heat dispersion.2, the constant current accuracy of the constant-current supply of light fixture and working life.And some the LED Projecting Lamps on the market do not have this type of problem of practical solution, are prone to cause unnecessary waste, have influenced economic benefit.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of good heat dissipation effect is provided, the LED Projecting Lamp of constant-current supply stable accuracy.
A kind of LED Projecting Lamp; Comprise housing and be installed in the led light source assembly in the housing; Said housing is made up of die casting aluminium upper shell and die casting aluminium lower house; Said die casting aluminium lower house bottom surface is evenly equipped with some radiating fins integrated with it; Be provided with in this die casting aluminium lower house and be used to place the power pack that is connected the power supply module on the three core power lines, said power supply module is connected with the led light source electrical component of die casting aluminium lower house another side, and layer is furnished with lens subassembly, face glass between said led light source assembly and the die casting aluminium upper shell.
Between said die casting aluminium upper shell and the face glass, be equipped with silica gel sealing ring between power supply module and the power pack.
Said led light source assembly and cast aluminium lower house are bonding through silica gel.
The utility model is easy for installation, good heat dissipation effect, and it is good to go out light effect, long service life.
