Abstract
The utility model provides a large-power LED illuminating lamp which comprises a shell and a lamp body arranged in the shell, wherein the lamp body comprises a light source chamber, an electric apparatus chamber and a radiator, wherein the light source chamber is internally provided with an LED dotmatrix module, the electric apparatus chamber is internally provided with a voltage-stabilizing circuit, the LED dotmatrix module is formed by a plurality of LED luminous sources which are welded on a PCB circuit board regularly; and the PCB circuit board is connected with the voltage-stabilizing circuit and the radiator, and the lamp body is also provided with a plurality of lenses which are covered on the LED luminous sources so as to be used for adjusting the irradiation angle and the irradiation strength of the light. The large-power LED illuminating lamp has the following technical effects: 1. the large-power LED illuminating lamp adopts the structure that one LED light source corresponds to one lens so as to lead the light strength distribution curve of a single LED light source to approach or reach national standard; and 2. as the rotatable lens is adopted, light distribution can be controlled, and the illuminance is very uniform in an effective irradiation area.
Description
Technical field
The utility model relates to a kind of LED lamp, specifically, relates to a kind of high-power LED illuminating lamp.
Background technology
Light emitting diode (LED) is a kind of solid state device that can be converted into electric energy luminous energy, and its structure mainly is made up of systems such as PN junction chip, electrode and optics.The basic functional principle of LED is the process of an electric light conversion, when a forward bias puts on the PN junction two ends, because the reduction of PN junction potential barrier, the positive charge in P district will spread to the N district, the electronics in N district forms the accumulation of non-equilibrium electric charge simultaneously also to the diffusion of P district in two zones.Because it is unstable relatively that electric current injects the minority carrier that produces, for the PN junction system, be injected in the valence band non-equilibrium hole will with the electron recombination in the conduction band, wherein unnecessary energy will be with the form of light to external radiation, the energy difference in electronics and hole is big more, and the photon energy of generation is just high more.Energy is differential to vary in size, and it is just different with wavelength to produce light frequency, and the color relation of corresponding light can be different.
High-powered LED lamp has advantages such as volume is little, power consumption is little, heating is little, the life-span is long, response speed is fast, safe low-voltage, good weatherability, good directionality as lighting source.Great power LED in the oil field, special industry, landscape light in city, display screen and stadiums etc. such as petrochemical industry, railway, mine, army, being with a wide range of applications in the Special Work light fixture.
Because the conversion efficiency of high-powered LED lamp is also lower at present, luminous flux is less, the restriction of the more high aspect of cost factor, so high-powered LED lamp application in a short time mainly is the Special Work light fixture that is confined to some special dimensions, also fails to apply in the general illumination field.
The utility model content
The purpose of this utility model is to solve the deficiencies in the prior art part, and a kind of high-power LED illuminating lamp that can carry out secondary distribution to light is provided.
High-power LED illuminating lamp of the present utility model, comprise shell and be located at the interior lamp body of shell, wherein lamp body comprises light source chamber, electric apparatus room and radiator, be provided with the LED lattice module in the light source chamber, be provided with mu balanced circuit in the electric apparatus room, the LED lattice module is welded on the PCB circuit board by rule by a plurality of LED light emitting sources to be formed, the PCB circuit board links to each other with radiator with mu balanced circuit, also be provided with a plurality of lens on the said lamp body, cover on the LED light emitting source, be used to adjust the exposure intensity of the irradiating angle and the light of light.
Preferably,
High-power LED illuminating lamp of the present utility model, its lens are rotatable lens.
More preferably,
High-power LED illuminating lamp of the present utility model, the quantity of its lens is identical with the quantity of LED light emitting source, all is covered with lens on each LED light emitting source.
High-power LED lighting fixture of the present utility model has following technique effect:
1, high-power LED illuminating lamp of the present utility model adopts the structure of the corresponding lens of a led light source, make single led light source the curve of light distribution near or be up to state standards;
2, owing to adopt rotatable lens, can control distribution of light, illumination is very even in effective irradiation area.
