Abstract
The invention relates to a high-power LED (light-emitting diode) flat plate lamp provided with a metal heat abstractor. The lamp comprises a lamp shell, light sources, a heat rejection aluminium plate and a lens, wherein the lamp shell and the lens form a cavity used for containing the light sources and the heat rejection aluminium plate; the heat rejection aluminium plate is arranged in the cavity and directly arranged on the inner wall of the lamp shell, and the light sources are successively arranged on the heat rejection aluminium plate and face to the end at which the lens is positioned; and each side face and the bottom surface of the heat rejection aluminium plate are provided with a plurality of heat rejection ports, each heat rejection port forms a heat rejection channel in the heat rejection aluminium plate, and the heat rejection channels are mutually arranged in a dislocation manner and are mutually communicated. The high-power LED flat plate lamp provided by the invention has the characteristics of large heat rejection area, good heat rejection effects and the like.
Description
Technical field
The present invention relates to a kind of great power LED planar lamp that is provided with the heat dissipation metal device.
Background technology
In recent years; The parent who more and more receives society along with the LED light fixture with characteristics such as low-carbon (LC), energy-saving and environmental protection, life-span length looks at; And the existence of the LED flat lamp in the existing LED light fixture is few with the volume area of dissipation, radiating effect is poor, quality heavily waits shortcoming; Concerning as the high-power flat light fixture of continuous illumination, this LED planar lamp be dangerous, power consumption is big, can not satisfy the demands.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, the great power LED planar lamp that is provided with the heat dissipation metal device of characteristics such as a kind of area of dissipation is big, good heat dissipation effect, light weight is provided.
For realizing above-mentioned purpose, the present invention is a kind of great power LED planar lamp that is provided with the heat dissipation metal device, and wherein, this light fixture comprises lamp housing, light source, heat-dissipating aluminium plate and lens, and described lamp housing and lens form a cavity that holds light source and heat-dissipating aluminium plate; Heat-dissipating aluminium plate is provided with in the cavity, and heat-dissipating aluminium plate is set directly on the inwall of lamp housing, and light source is arranged in order and is arranged on the heat-dissipating aluminium plate and the end towards the lens place; Each side of heat-dissipating aluminium plate and bottom surface all offer some thermovents, and each thermovent all forms heat dissipation channel in heat-dissipating aluminium plate inside, and mutual dislocation is arranged and is interconnected between each heat dissipation channel.
Adopt heat-dissipating aluminium plate to be set directly on the inwall of lamp housing, can make lamp housing form a radiating surface, improved radiating effect, increased area of dissipation so that a part of heat of heat-dissipating aluminium plate can be delivered on the lamp housing; Not only improved the effect that heat transmits on the heat-dissipating aluminium plate because light source is set directly at, also reduced light source board, thereby saved material; Adopt the some heat dissipation channels of heat-dissipating aluminium plate set inside, mutual dislocation and connection between the heat dissipation channel; Each heat dissipation channel all has certain area cavity, and the certain area of dissipation of the heat radiation of LED, this heat-dissipating aluminium plate can utilize the cubic metal characters or patterns structure of a plurality of heat dissipation channels, under the situation with volume, has bigger area width and passage; Improve radiating effect, reduced the quality of heat-dissipating aluminium plate.
Wherein, the bottom of described light source is embedded in the upper surface of heat-dissipating aluminium plate.Adopt the mode of this embedded type to make the heat of light source to be delivered to fast on the heat-dissipating aluminium plate, dispel the heat through heat-dissipating aluminium plate.
Wherein, offer ventilating groove on the described lamp housing.On lamp housing, offer ventilating groove, can accelerate radiating effect, improved heat dispersion.
Wherein, described ventilating groove is positioned near the light source.Because light source can produce a large amount of heat,, can improve heat dispersion so adopt ventilating groove to be positioned near the light source.
