Abstract
The invention discloses a cross-ventilation radiating high-power LED lamp, comprising an LED light source, an aluminium base board and an arch and cylindrical shell, wherein the arch and cylindrical shell consists of an inner shell and an outer shell; the two end faces of the arch and cylindrical shell have openings, thus forming cavities; the LED light source is arranged on a base board which is clung to the bottom surface of the inner shell; the bottom surface of the inner shell is provided with a plurality of strip bulges extending towards inside of the cavity; a convection air flue is arranged between every two adjacent axial strip bulges; and a reflecting plate is arranged between the axial side edge of the base board and the axial side edge of the inner shell. Since a cross-ventilation radiating channel is arranged and air convection exists at the left side and the right side, the LED lamp of the invention is favor for discharging heat and has no heat accumulation effect, thereby effectively improving the heat conduction efficiency of the LED light source, effectively reducing optical attenuation and improving the service life of the LED light source.
Description
Technical field
The present invention relates to a kind of illumination lamp, particularly a kind of cross-ventilation radiating high-power LED lamp.
Background technology
Progressively enforcement along with the energy-saving and cost-reducing requirement of national Eleventh-Five Year Plan, domestic every profession and trade responds to the call, the various energy-saving and cost-reducing specific practices of numerous and confused proposition, semiconductor LED illumination emerging in the illuminating industry also has various LED light fixtures to carry out actual energy-saving and cost-reducing action at each lighting field.General LED light fixture all is to adopt aluminium base to add radiator to transform in ordinary lamp and lantern inside and form, the solid matter of great power LED is used, and the drawback of light fixture ubiquity sealing, the difficulty of distributing that causes heat, general LED light fixture is that its radiating effect is bad in the lamp interior heat radiation, does not satisfy the LED normal operating conditions at all, also accelerated the light decay of LED greatly, made its lost of life; Aluminium base generally is flat in addition, do not have refraction and reflective booster action, do not guarantee the distribution consistency degree of hot spot length and light, make light occur stack and waste easily, do not have the effect of complete energy-saving consumption-reducing, its brightness does not reach every luminance index of national Specification yet.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art, a kind of cross-ventilation radiating high-power LED lamp of empty calory build-up effect is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of cross-ventilation radiating high-power LED lamp, comprise led light source, substrate and arc cylindrical shell, described arc cylindrical shell is made up of inner housing and shell body, arc cylindrical shell both ends of the surface opening forms cavity, and led light source is arranged on the substrate, and substrate touch the inner housing bottom surface, a plurality of axial strip projected parts are stretched out in the bottom surface of inner housing in cavity, form the convection current air channel between the adjacent axial strip projected parts.
As further improved technical scheme of the present invention, also comprise two end caps, be installed in respectively on two end faces of arc cylindrical shell, end cap also is opening with the cavity hatch place of coincidence.
As further improved technical scheme of the present invention, also comprise two reflectors, be arranged between the axial side of the axial side of substrate and inner housing, described reflector is the aluminium reflector, described substrate is an aluminium base.
As further improved technical scheme of the present invention, also comprise Transparent lamp shade, Transparent lamp shade is installed on two axial lateral end panels of arc housing, and described Transparent lamp shade is a safety glass.
As further improved technical scheme of the present invention, also comprise buckle, clinching, clinching hinge plate, swivel plate and rotation hinge plate; Buckle and swivel plate are connected with the end face of an axial side of arc cylindrical shell respectively, and the axial side of Transparent lamp shade is buckled in buckle and swivel plate; Clinching one end is movably arranged on the lateral surface of shell body, and another side is hook-shaped free end, and hook-shaped free end is buckled on the buckle; Clinching hinge plate withstands clinching, and the one end is installed on the shell body, and the other end is installed on the inner housing; Rotation hinge plate one end is movably connected in the bottom of the axial sides of inner housing, and the other end is connected on the swivel plate.
The present invention is provided with cross-ventilation formula aluminium matter heat dissipation channel, increased area of dissipation, there is cross-ventilation the left and right sides, strengthened the circulation of air of lamp body itself, helped the discharge of heat, the empty calory build-up effect, thereby effectively raise the heat conduction efficiency of led light source, guarantee that high-power LED light source in the safe working temperature below 45 ℃, effectively reduces light decay, improved the service life of led light source; Adopt the aluminum alloy materials of high thermal conductivity coefficient, effectively reduce windage and weight, alleviate the load of lamp stand, safe and reliable, in addition, by reflector is set, utilize the directional light distribution technology to carry out secondary optics " banded hot spot " bright dipping, thereby reasonably control the distribution of light, avoid the stack waste of light, reduced the light loss consumption, realized being connected to each other of banded hot spot between the lamp stand, when guaranteeing the desirable road illumination and the uniformity, eliminated the LED dazzle, the effect that makes it play energy-saving consumption-reducing fully and guarantee brightness.
