Abstract
The invention discloses an ultrahigh-power LED lamp with good heat dissipation performance. The ultrahigh-power LED lamp with the good heat dissipation performance comprises a housing and a light source circuit board. The housing is made of aluminum alloy. Heat conductors are arranged on the upper surface of the housing. The housing further comprises an upper housing body and a lower housing body. The upper housing body has a waterproof function and a dustproof function. The light source circuit board is fixed to the lower surface of the housing through the lower housing body. According to the ultrahigh-power LED lamp with the good heat dissipation performance, due to the facts that the housing is made of aluminum alloy and the heat conductors are arranged on the upper surface of the housing, the problem of large weight is solved, effective heat dissipation is achieved, and thus the service life of the street lamp is prolonged. Meanwhile, the ultrahigh-power LED lamp with the good heat dissipation performance is reasonable in structural design, waterproof, rainproof and shockproof, dirt is unlikely to be accumulated in the lamp, and convenience is brought to maintainers, pedestrians and vehicles.
Description
Technical field
The present invention relates to a kind of decorating lighting lamp, especially a kind of good superhigh power LED lamp of heat dispersion for the illumination of the public arena such as street, highway.
Background technology
Along with popularizing of scientific and technological progress and environmental protection concept, LED lighting engineering has obtained application comparatively widely. Because LED is the faint just luminous high efficiency solid-state light source of energy of electric energy of use that a kind of based semiconductor PN junction forms, under certain forward bias voltage and Injection Current, the electronics that injects the hole in P district and inject N district sends photon through radiation recombination diffusing to after active area, electric energy is converted into luminous energy, therefore LED is far superior to traditional lighting product in the aspect of principle of luminosity, energy-saving and environmental protection, so the superhigh power LED lamp that heat dispersion is good becomes the optimal selection of road lighting, traditional incandescent lamp and common energy-saving lamp are replaced gradually. But, present most of LED lamps on the market, the weight of heat-dissipating casing is heavier. and light efficiency is lower, but the design of structure is unreasonable, easily piles up foreign material.
Summary of the invention
The object of the invention is for solve prior art shell weight heavier, easily pile up the problems such as foreign material, radiating effect are poor, provide a kind of by increasing efficiently radiates heat area, thereby reach the weight that both reduces street lamp, strengthen rational in infrastructure, light efficiency is high, heat dispersion the is good superhigh power LED lamp of heat sinking function simultaneously.
Object of the present invention can be by taking following technical scheme to realize:
The superhigh power LED lamp that a kind of heat dispersion is good, comprise shell, light source circuit board, described shell by aluminium alloy make, upper surface is provided with heat transfer device, shell also comprises upper casing and lower casing, described light source circuit board is fixed on the lower surface of shell front portion by cover.
Object of the present invention can also be achieved through the following technical solutions:
Realizing a kind of embodiment of the present invention is: described anti-upper casing and lower casing can be the structure that adopts aluminium sheet to make.
The present invention has following outstanding beneficial effect:
Shell of the present invention is made up of the good aluminium alloy of heat dispersion, and upper surface has also been set up heat transfer device, has both solved the heavier problem of weight, has also reached efficiently radiates heat simultaneously, thereby improves life-span and the LED lamp power of street lamp.
Brief description of the drawings
Fig. 1 is the assembling schematic diagram of the specific embodiment of the invention 1.
Wherein, 1-shell, 1-1-heat transfer device, 1-2-upper casing, 1-3-lower casing, 2-lens module.
Detailed description of the invention
Fig. 1 has formed specific embodiments of the invention 1.
With reference to Fig. 1, the present embodiment comprises shell 1, light source circuit board 2, described shell 1 by aluminium alloy make, upper surface is provided with heat transfer device 1-1, described upper casing 1-2 is fixed on the top of heat transfer device 1-1, described light source circuit board 2 is fixed on shell 1 lower surface by lower casing 1-3. Described heat transfer device 1-1 surface is covered with the heat conduction raised line of protrusion, so greatly increase area of dissipation, thereby the heat that light source circuit board 2 produces is left rapidly by shell and heat transfer device, the intensification of having guaranteed like this light source circuit board 2 is low, thereby effectively alleviate the weight of whole street lamp, also postponed service life and the LED lamp power of street lamp.
The above; it is only preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the disclosed scope of the present invention; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, all being belonged to protection scope of the present invention.
