Abstract
The invention relates to an LED (Light Emitting Diode) lighting lamp of a compartment of a high-speed train, which comprises 222 light emitting diodes, wherein the 222 light emitting diodes are arranged on a lamp at the top of the compartment of the high-speed train in two rows with 111 light emitting diodes in each row, and the total luminous flux of the 222 light emitting diodes is 2000-2200lm. In the invention, only 20W power is consumed within one meter, and the illumination in the compartment can reach 200Lx, while over 40W power is needed within one meter if a traditional fluorescent lamp needs to reach 200Lx; thus, the lamp has obvious energy-saving and environment-friendly effects.
Description
Technical field
The present invention relates to a kind of bullet train compartment LED lighting light fixture.
Background technology
Lighting requires in the bullet train compartment: both can't see illuminator, and reached the illumination requirement of 200Lx again, and reduced energy consumption simultaneously as far as possible.
The purpose of illuminator is can't see in requirement: from the psychologic angle of throwing light on, and natural imitation light, it is comfortable and easy that the passenger is done in the compartment.Otherwise the passenger sees illuminator or dazzle is arranged, and makes the passenger produce the sensation of anxiety, agitation.
Want the purpose of the illumination of 200Lx: make the passenger see thing, can not make eye fatigue.
The light source of illumination mainly contains two kinds at present: a kind of LED of being (Light Emitting Diode) is the abbreviation of light emitting diode, and the light source luminescent angle of LED generally is about 120 °; Another kind is a fluorescent lamp.360 ° of its lighting angles.But select the fluorescent lamp of 360 ° of lighting angles for use, then most of light is blocked by light trough, even the groove inner face has reflection, also has only the light of minute quantity, and effective rate of utilization can not surpass 20% yet, is not wise selection so select fluorescent lamp for use.
LED lighting Design of Luminaires in bullet train compartment is exactly how to select suitable light source, carries out the science luminous intensity distribution, reaches lighting requirement in the bullet train compartment.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of a kind of bullet train compartment LED lighting light fixture with tangible energy-saving and environmental protection effect is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bullet train compartment LED lighting light fixture, comprise 222 light emitting diodes, described 222 light emitting diodes divide two rows to be arranged on the light fixture of bullet train carriage top portion, every row is 111 light emitting diodes, and the total logical light quantity of described 222 light emitting diodes is 2000～2200lm.
Specifically, 111 light emitting diodes of two a rows of the present invention wherein row are 5050 type light emitting diodes, and another row is 3528 type light emitting diodes.Every meter total light flux of 5050 type light emitting diodes is 1500～1650lm, and every meter total light flux of 3528 type light emitting diodes is 500～550lm.
Wherein, the effect of 5050 type light emitting diodes is that the light that sends in groove is used for key lighting by the ceiling reflection; And 3528 type light emitting diode effects be on ceiling from the trough rim to the center, its light by strong to a weak progressive formation.Both lighting angles all are 120 °.
Light fixture of the present invention places in the groove of compartment two side roof parts, and the people can't see light fixture in the compartment, at the illumination 200Lx from 0.8 meter, ground, compartment.
The invention has the beneficial effects as follows, solved the defective that exists in the background technology, adopt every meter power of only using 20W of the present invention, just make the compartment intraoral illumination reach 200Lx, and traditional fluorescent lamp will reach 200Lx, want more than the 40W at least for every meter, so this light fixture has tangible energy-saving and environmental protection effect.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Fig. 2 is the end face enlarged drawing of Fig. 1;
Among the figure: 1,5050 type light emitting diodes; 2,3528 type light emitting diodes; 3, light fixture.
The specific embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of bullet train compartment LED lighting light fixture as shown in Figure 1, 2, comprise 222 light emitting diodes, described 222 light emitting diodes divide two rows to be arranged on the light fixture 3 of bullet train carriage top portion, every row is 111 light emitting diodes, wherein a row is 5050 type light emitting diodes 1, another row is 3528 type light emitting diodes 2, and the total logical light quantity of described 222 light emitting diodes is 2000～2200lm.
Compared with prior art, adopt the mode of selecting LED, then effective rate of utilization is 48%, far surpasses the effective rate of utilization of fluorescent lamp.So selecting LED for use is wise selection.Be the effective rate of utilization of calculating led light source below: because the density curve of its light is a parabola, its mathematical function is: P (x)=1-x2 ÷ 902, wherein ,-90≤x≤90.
Effective rate of utilization then: E=∫-30+30P (x) dx ÷ ∫-90+90P (x) dx=58 ÷ 120=48%.
Calculate the luminous flux phi that every meter light source needs:
Railway car is to be the space of a sealing basically, and according to measurement, the average light reflectivity around it: ρ=29%, its light can infinite reflection in the compartment.So total light flux is:
ΦT＝ρΦE+ρ2ΦE+ρ3ΦE+…+ρiΦE+…i＝1，2，3，…，+∞
Φ T=ρ Φ E ÷ (1-ρ)=0.408 Φ E is the Φ E luminous flux that utilizes effective light that to be light source send in the groove wherein
The illumination that requires in the railway car is 200Lx, and the railway car insied width is 3 meters, and then the compartment is 3m2 at the area of 1 meter of length, and luminous flux is 600Lm (=200 * 3) in the space.Be Φ T=600, so
ΦE＝ΦT÷0.408＝600÷0.408＝1469(Lm)
So every meter luminous flux that light source needs: Φ=Φ E ÷ 48%=3,060 (Lm)
So every meter total light flux of LED light source for illuminating is 3,060Lm, compartment every meter luminous flux of two-side lighting light source is respectively 1530Lm.Aforementioned calculation does not consider that in order to simplify the LED of 3528 types sends the extra luminous flux effects that increase such as factor of light, so every meter luminous flux of both sides, compartment key lighting 5050 type led light sources is respectively 1500Lm, just can reach requirement.
Just the specific embodiment of the present invention of describing in the above specification, various not illustrating is construed as limiting flesh and blood of the present invention, the person of an ordinary skill in the technical field after having read specification can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
