Description
Technical field
The utility model relates to a kind of light illumination, particularly relates to a kind of monomer light source with low-power LED.
Background technology
Along with the development that urban construction is maked rapid progress, the environment that people live is improved hugely, rises sheer from level ground in blocks of new residential quarters, and the sub-district illuminating engineering is put in face of engineering design person as a problem.Consider that from light source present employed light source major part is based on sodium vapor lamp, mercury lamp, electricity-saving lamp and some conventional fluorescent lamps.These light sources objectively all exist the defective that is difficult to overcome.Shorter as the life-span, the power consumption height, luminous efficiency is low, color rendering index is low, working temperature is high, maintenance cost is high.In order to overcome these defectives, engineers and technicians consider to replace the light source used always with this new light sources of LED.Wherein LED is divided into two kinds of high-power and small-powers again, adopts great power LED more at present, though its advantage is very outstanding, it also has the defective that is difficult to overcome, and too high user is difficult to bear as cost, and the working temperature high product is damaged easily.Low-power LED is generally just used in advertising lighting, and gross power is less, because outdoor lighting brightness higher to the quality requirement of light fixture, light source is higher, working temperature is low, the restriction low-power LED is in the application of outdoor lighting.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes existingly to be the shortcoming of the supporting light source of residential quarters light fixture, and the modular low-power LED that a kind of life-span is long, low in energy consumption, luminous efficiency is high, color rendering index is high, working temperature is low new light sources is provided.
The technical scheme that the utility model adopted is: a kind of low-power LED monomer light source comprises: Switching Power Supply and luminous monomer; The input of Switching Power Supply is an alternating current 220V, is output as DC12V, is electrically connected with the parallel circuit of luminous monomer respectively by main circuit, is connected in parallel between each luminous monomer.
Described luminous monomer is made up of LED, current-limiting resistance and printed substrate; Described LED has many, and the luminous monomer of its composition is 1 to 3W.
Described luminous monomer is 1W.
The shape of described luminous monomer can be rectangle, triangle, circle, square, trapezoidal and oval.
The beneficial effects of the utility model are: with receiving that lamp compares under the isometropia condition with the low-power LED is that the light fixture of light source can economize on electricity more than 60%; Low-power LED useful life ordinary circumstance about 10 years, maintenance cost is very low; Because low-power LED is hemispherical luminous, lighting angle can be made by set angle when making, and does not need reflector.Low-power LED is as new type light source, and the life-span that it had is long, low in energy consumption, luminous efficiency is high, color rendering index is high, low being highly suitable in the residential quarters of working temperature promoted the use of.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1 to Figure 3, the utility model low-power LED lamp comprises: Switching Power Supply and luminous monomer 10; The input of Switching Power Supply is an alternating current 220V, is output as DC12V, is electrically connected with the parallel circuit of luminous monomer 10 respectively by main circuit, is connected in parallel between each luminous monomer 10; The quantity of luminous monomer will be determined according to specification requirements such as the scope of application of light fixture, irradiation distance, color temperature index number, power index, shooting angles.Described luminous monomer is made up of LED11, current-limiting resistance 12 and printed substrate 13; Described LED11 has many, and the luminous monomer 10 of its composition is 1 to 45W.Optimal selection is that luminous monomer 10 is 1W.The shape of described luminous monomer 10 can manufacture rectangle, triangle, circle, square, trapezoidal and ellipse etc. according to the external form of light fixture.Luminous monomer both can independently use also and can make up mutually, and its power bracket is between 1W～45W, and the shooting angle of every LED pipe is between 15 °～120 °.The monomer of low-angle LED combination, emitted optical beam ratio are concentrated and are fit to small-sized flood light, are used to shine trees, view, advertisement, but also can set off the atmosphere of photographed object by contrast with the LED of different colours (red, yellow, blue, green).The LED of 30 °～60 ° of left and right sides angles of emergence can be used for street lamp, because the LED of this shooting angle, its brightness is higher, and the structure according to street lamp cap can be installed in the luminous monomer of LED in the lamp body by required angle simultaneously, thereby satisfies by the brightness of illumination range.Can also load in mixture with the luminous monomer of LED of low colour temperature and high colour temperature, form mixed light sources to improve the irradiation quality of light fixture.The LED of 60 °～90 ° of left and right sides angles of emergence can be used for small-sized floodlight, is applicable to the illumination in square, sub-district, CRUX place, and LED should select low colour temperature, warm-toned for use, and the light of this specification LED is very soft.The LED of the angle of emergence can form spherical illuminating source more than 90 °, it is made up of transparent or semitransparent lampshade, the luminous monomer of LED, Switching Power Supply, E27 socket, it of many uses, every theoretically with the E27 socket light fixture if cover mouthful enough big it all be suitable for.In the illumination of sub-district, it is highly suitable for garden lamp, the most Lawn lamp of determining of height about 3M.
The technical solution of the utility model is suitable for the sub-district by adorning new lamp, owing to be newly-built sub-district, light fixture just can be optimized design according to the total arrangement of sub-district, and this comprises the parameters such as profile, power, color rendering index, shooting angle of light fixture.Because of the power of LED is little, so the cross-section of cable just can be than reducing much with other light source, the capacity of power transformation cabinet also can reduce, and economic benefit is obvious.And need not safeguard that for a long time maintenance costs is very low.This technical scheme also is suitable for old lamp transformation simultaneously, transforms as will using the light source in the light fixture, and power consumption light source high, fragile, that color rendering index is low is changed.Its advantage is that the expense of transforming is few, need not to destroy the situation of original light fixture and environment facies harmony; Because the light source overall power descends, the electric current of cable carrying reduces, and the life-span of cable is prolonged.Descend because of transforming the back overall power, the electricity charge also can decline to a great extent.Very long because of the LED life-span simultaneously, maintenance cost also can decline to a great extent.
The selection of parameter: the Switching Power Supply with a stable performance provides stable voltage DC12V for LED, determines the capacity of Switching Power Supply according to the power of LED.Switching Power Supply is made up of electronic components such as diode, triode, transformer, resistance capacitances, indexs such as withstand voltage to it when selecting these electronic components for use, overcurrent, power, working temperature are reserved surplus capacity, particularly electrochemical capacitor will be selected high temperature resistant, long-life product, the capacitance index will be stayed bigger surplus capacity, each Switching Power Supply all will be made water-proofing treatment, so that in outdoor application.
It is worthy of note; protection range of the present utility model is not limited to above-mentioned instantiation mode, according to basic fundamental design of the present utility model, as long as those of ordinary skills need not through creative work; the execution mode that can associate all belongs to protection range of the present utility model.
