The specific embodiment
The lighting device of present embodiment light-emitting component with different luminous fluxes on lamp plate carries out permutation and combination, to obtain uniform lighting source.Traditionally, if use the light-emitting component of same light flux to be arranged on the lamp plate, when going to assemble with the higher light-emitting component of brightness ratio, required light-emitting component quantity is less relatively, but the unit price cost of the high light-emitting component of brightness is higher relatively; Otherwise when go assembling with the lower light-emitting component of brightness ratio, though the unit price cost is relatively low, required light-emitting component quantity is more relatively, so whole cost is reduced.In addition, constant down at total light flux, when the brightness of light-emitting component is high more,, cause spacing excessive and form so-called bright spot (Hot spot) easily because the negligible amounts of required light-emitting component will certainly widen the spacing between light-emitting component.
So; For under the condition that does not reduce the integral light flux; The bright spot that is improved problem and take into account product cost, present embodiment carries out permutation and combination with the light-emitting component of different luminous fluxes, not only can dwindle the spacing between adjacent two light emitting; And can let the luminous flux in clear zone and dark space does not have obvious variation on the lamp plate, and then obtain uniform lighting source.
For instance, with four chi fluorescent tube specifications, length is 1200mm, if the brightness of 1600 lumens will be provided:
One embodiment of the utility model is to use 28 80 of light-emitting components with 6 lumens of light-emitting component of 40 lumens to come permutation and combination, and every average headway is approximately 1200mm/ (28+80)=11.11mm.
With respect to traditional practice is single use light emitting element with high brightness, and 40 of the light-emitting components of 40 lumens for example are though luminous flux is constant; But its average headway is 1200mm/40=30mm; Much larger than standard value (for example 15mm), luminous point will be very obvious, can't meet standard.So if will improve bright dark inequality, just must reduce electric current, improve granule number, for example through reducing electric current and the light-emitting component to 80 of 40 lumens being provided, to dwindle spacing and to meet standard value 15mm.
In addition; Consider down at the cost of same light flux,, carry out permutation and combination with the light-emitting component of different luminous fluxes if the price differential of the lower light-emitting component of higher light-emitting component of unit price and unit price is greater than more than 2.5 times the time; Can reduce cost, make lighting device have more price competitiveness.
For instance, the unit price of the high illumination element of 40 lumens is A, and the unit price of the low-light level light-emitting component of 6 lumens is B, with real price in the market, and about A=3B, the cost of comparison of aforementioned conventional practice and this case embodiment:
Conventional practice needs 80 high illumination element that 40 lumens can be provided, so cost is 80A=240B; The embodiment of the utility model needs 28 high illumination element and 80 low-light level light-emitting components that 6 lumens can be provided that 40 lumens can be provided, so cost is 28A+80B=164B.
So cost decline percentage (240B-164B)/240B=31.67%., hence one can see that, uses the utility model that cost is descended significantly, with the competitiveness of improving price.
Below propose embodiment and be elaborated, embodiment in order to as the example explanation, is not the scope in order to the protection of limit the utility model desire only.
First embodiment
Fig. 2 A illustrates the sketch map according to the lighting device of the utility model one embodiment.Lighting device 100 for example is a fluorescent tube, and it comprises a lamp plate 110 and a tubular body 120.Lamp plate 110 is arranged in the tubular body 120, and lamp plate 110 is in order to being provided with at least one row's light-emitting component 130, and makes light-emitting component 130 receive driven and luminous.Though present embodiment only illustrates row's light-emitting component 130, do not limit and have only row's light-emitting component 130, also can arrange light-emitting component 130 more.Wherein, the light-emitting component preferred embodiment of the utility model can be light emitting diode.
Please with reference to Fig. 2 B～Fig. 2 D, it illustrates the sketch map of the local arrangements combination of lamp plate 110 and light-emitting component 130 thereof among Fig. 2 A respectively.Light-emitting component 130 comprises the light-emitting component 132 of a plurality of tool first luminous fluxes and the light-emitting component 134 of a plurality of tool second luminous fluxes.First luminous flux is greater than second luminous flux, and is provided with the light-emitting component 134 of tool second luminous flux between the light-emitting component 132 of wantonly two tool first luminous fluxes at least.Preferably, for example between 40～30 lumens, for example between 6～10 lumens, the proportionality of first luminous flux and second luminous flux is as between 3～7 for second luminous flux for first luminous flux.Though present embodiment is represented the light-emitting component 132 of tool first luminous flux with larger-size light-emitting component; And represent the light-emitting component 134 of tool second luminous flux with the less light-emitting component of size; But size just schematically; In fact size does not have relevantly for the luminous flux size, and this case can change luminous flux through adjustment voltage or current value, but also can change light-emitting area through increasing/minification.
With quantity, the quantity of the light-emitting component 132 of tool first luminous flux can be equal to or less than the quantity of the light-emitting component 134 of tool second luminous flux, for example is respectively 28 and 80.If the light-emitting component with 40 lumens and 6 lumens is an example, its integral light flux is 28x40 lumen+80x6 lumen=1600 lumens, is equivalent to use the luminous flux that light-emitting component produced of 40 40 lumens.Therefore, under the constant condition of integral light flux, the quantity of spendable light-emitting component 130 relatively increases (108 altogether), makes light-emitting component 130 arrange more closely, to dwindle spacing.
Permutation and combination shown in Fig. 2 B, the light-emitting component 132 of tool first luminous flux is staggered on lamp plate 110 with the light-emitting component 134 of tool second luminous flux, and is that equidistant D1 arranges.Then, the permutation and combination shown in Fig. 2 C, the light-emitting component 132 of tool first luminous flux is staggered on lamp plate 110 with the combination of the light-emitting component 134 of tool second luminous flux with 1-2-1, and is equidistant D2.That is to say that the light-emitting component 134 of two tool second luminous fluxes is arranged between the light-emitting component 132 of two tool first luminous fluxes.Then, the permutation and combination shown in Fig. 2 D, the light-emitting component 132 of tool first luminous flux is staggered on lamp plate 110 with the combination of the light-emitting component 134 of tool second luminous flux with 1-3-1, and is equidistant D3.That is to say that the light-emitting component 134 of three tool second luminous fluxes is arranged between the light-emitting component 132 of two tool first luminous fluxes.
On driven, the light-emitting component 132 of tool first luminous flux for example links to each other with the mode of serial or parallel connection, and the light-emitting component 134 of tool second luminous flux for example links to each other with the mode of serial or parallel connection.The light-emitting component 132 of tool first luminous flux can distinctly drive by different driving voltage with the light-emitting component 134 of tool second luminous flux.If when the voltage after light-emitting component 134 series connection of the voltage after 132 series connection of the light-emitting component of first luminous flux and second luminous flux is identical, then can drive simultaneously by identical driving voltage, with the saving assembly cost.

Please with reference to Fig. 3 B～Fig. 3 D, it illustrates the sketch map of the local arrangements combination of lamp plate and light-emitting component thereof among Fig. 3 A respectively.Each is arranged light-emitting component 230 and comprises the light-emitting component 232 of a plurality of tool first luminous fluxes and the light-emitting component 234 of a plurality of tool second luminous fluxes.First luminous flux is greater than second luminous flux, and has the light-emitting component 234 of one second luminous flux between the light-emitting component 232 of two tool first luminous fluxes at least.
Permutation and combination shown in Fig. 3 B, the light-emitting component 232 of tool first luminous flux of each row is staggered on lamp plate 210 with the light-emitting component 234 of tool second luminous flux, and arranges with equidistant D1.Then; Permutation and combination shown in Fig. 3 C; The light-emitting component 232 of tool first luminous flux of each row is staggered on lamp plate 210 with the combination of the light-emitting component 234 of tool second luminous flux with 1-2-1; That is to say that the light-emitting component 234 of two tool second luminous fluxes is arranged between the light-emitting component 232 of two tool first luminous fluxes.Then; Permutation and combination shown in Fig. 3 D; The light-emitting component 232 of tool first luminous flux of each row is staggered on lamp plate 210 with the combination of the light-emitting component 234 of tool second luminous flux with 1-3-1; That is to say, be provided with the light-emitting component 234 of three tool second luminous fluxes between the light-emitting component 232 of two tool first luminous fluxes.
