A lighting store loaded forced diary

This is a place for people to install the lighting diary.

Since it is forced to carry a diary, of course, must be loaded to force tools, oh no, is the crime tool!

Remember to check out before: cell phone, wallet, camera and lighting passport (I do not know what is the passport lighting, we chat in private life)

Of course, the most important thing is: a pair of good at (Deng Guang) beautiful eyes.

Objectives: large supermarket stores

Objective: pretend to do not consciously do the lighting evaluation in shopping, in order to achieve the loading effect.

Necessary knowledge points: Based on the basic lighting lighting knowledge

Small tips: the main task of basic lighting is to provide adequate and uniform illumination level for the shopping area, through the basic lighting system design, to create a pleasant and comfortable environment for the supermarket, from the physical to the psychological, to meet customer needs happy shopping.

Simply put, the customer, according to the good, but also afraid of TA do not pay for shopping.

Figure: Yes, this is the loading site.

Probe into the scene

As a professional lighting, came to the store, do not act rashly, first look at the container above the lights, look around there is no one (careful sales staff to stop you, then take out the camera).

Look at the scene......

Data analysis

This kind of cloth is right, is there any problem?

Illuminance: at this time on the loading force artifact - Lighting passport, the lamp with the illumination below the 800lx, two rows of lights with the middle of the illumination at around 650lx.

Evaluation: uniformity can also, but the display of goods on the shelf, the vertical illuminance is almost only 200lx.

Is this distribution of illumination conducive to product display and information transfer?

Ready to open the Curve Wrecker mode, each carefully.

1, cloth light mode

We can see that the underground layer of the shelf with the following lighting is the use of cloth lights, which is perpendicular to the lamp with the shelf:

First of all, this arrangement is not the most effective use of the lighting system, a number of unnecessary areas of the economy of the loss of lighting: such as the top of the shelf lighting, is an economic means of cloth. Differential evaluation!

Secondly, this kind of lighting can not provide sufficient vertical illumination to display goods shelves, which affects the display of goods and the transmission of visual information. Differential +1

The correct approach is to put the lights in the middle of the two rows of shelves, so as to ensure the basic lighting of the channel, while ensuring the vertical illuminance level on both sides of the shelf, to avoid the waste caused by the waste of light.

The wrong way?

Reasonable way?

2, the choice of lamps and lanterns

This store with lights is T8 support with bilateral control of herringbone cover, which basement is a grooved aluminum reflector (outdoor floodlights used) a layer of a mirror, aluminum reflector (poor quality, light ghosting and rainbow effect), as well as white plate reflector. Roughly the shape of the light, you can imagine.

And then through the wall spot, to find out about the light with the light:

Figure: the main light with two wings narrow, more than 30 degrees of light intensity

Figure: axial elliptical light intensity

This distribution of light, but also the use of this cloth light, we can understand why the vertical illuminance of the shelf is only 200lx so low.

So, in the middle of the cloth along the shelves, what kind of light curve fitting is the best? For the band, the answer is: bat wings.

For LED, the imagination is great, make full use of the characteristics of small size and lens LED, providing a corridor based lighting and vertical lighting of the shelves with LED lamp belt should not be difficult......

In fact, the mall in the wall shelf lighting using a double tube T8 fluorescent lamp wall lamp (wall washer), this time the shelf vertical illuminance reached nearly 400lx level. The mirror aluminum reflector material in general, the rainbow effect is obvious, the lamp efficiency should not be high, with the meaning of light, but very rough, more regrettable.

Figure: wash wall lamp with light (wall light), looks very high lamp, in fact, is a mirror reflector caused by the end of the mirror image

Of course, the shelf lighting is not just a band, as long as the basic needs of the shelf display (see the following line of sight analysis), you can use different methods to achieve.

In addition, on the quality of lighting, mainly color rendering, color temperature, glare control and visual brightness distribution, are the basic knowledge, secretly tell you, basic knowledge and office lighting can understand yo!
