In shop lighting, light is composed of space light + commodity light.

Good shop lighting needs to achieve these three purposes:

1. Attracting Customer's Attention
2. Make Customers Evaluate the Quality of Goods Correctly
3. Providing sufficient brightness to facilitate transaction

Common commercial lighting includes environmental lighting and key lighting. They are not equal in autumn. They either highlight a certain method to highlight the unique personality of the shop, or a lighting fixture to satisfy a variety of lighting effects. So how to apply it?

Environmental lighting

▼

Environmental lighting, as its name implies, provides uniform ambient light. It is the keynote of the whole space. Its purpose is to let customers see the goods clearly and the staff can complete the sales. Usually uniform lighting, uniform lighting, illumination is more than 50lx-1500lx.

【Common Techniques of Environmental Lighting】

Among them, the most common environmental lighting is tube lamp and lamp belt, which can easily create uniform lighting effect.

Brightening the walls to provide environmental lighting is more common in high-end stores, which can better show the texture of goods.

▲Brighten evenly and demonstrate correctly。

▲Brightness mottled, error demonstration.

When it comes to environmental lighting, there is a corresponding focus on lighting. However, there is no key lighting in the space, and environmental lighting is responsible for the whole shop. It is suitable for large passenger flow and self-service space. The main purpose of lighting is to provide sufficient brightness to facilitate the transaction. For example, supermarkets, fast food restaurants and so on.

▲UNIQLO is also the representative of providing the whole shop lighting with environmental lighting. The overall illumination is relatively high and there is no special focus on lighting.

▲Apple stores, which use uniform light-emitting flat panel as the main lighting mode, are cool and not easy to cause screen reflections.

Key lighting

▼

Key lighting, also known as display lighting in stores, is responsible for lighting specific objects, creating brightness changes and shadows or dramatic effects, so as to contrast the shape, structure, organization and color of goods with the environment, enhance their image and make them the focus of attention.

【Visual effects of different illumination coefficients】

▲Key illumination factor = 2, visual effect: relatively flat, slightly contrast.

▲Key Lighting Coefficient = 5

                                                                              Visual effects: low dramatic, with a sense of difference.
                                                                                                      It's a lot of scenes.

▲Key illumination factor = 15

Visual effect: dramatic, the difference between light and shade is obvious, shadows begin to emerge, so there is form.

Often used in expensive luxury goods, they require higher key lighting coefficients to become visual focus.

▲Key illumination factor = 30

Visual effect: vivid, there are shadows, people's three-dimensional sense is very vivid.

The most common model in the window.

▲Key illumination factor = 50

Visual effect: Very vivid, the spot is very clean.

Shadows are too heavy, or the whole environment of the shop is too abrupt, which is not conducive to the display of comfort, only suitable for stage lighting.

Different key illumination coefficients produce different proportion of light, creating a very different environment.

Sometimes in order to highlight the commodity, we need to use light to make a strong contrast. The key lighting requirements are brighter than the surrounding area. This means that the commodity and display stand should be at least 5 to 10 times brighter than the surrounding area, but too strong contrast is easy to cause visual discomfort. When do we need to think about using comfortable light? When is the eye-catching light used?

Comfortable lighting needs to control the brightness. Usually, the illumination ratio should not exceed 5:1 in the adjacent area. For example, the desktop illumination is usually 300 lx, and the ambient illumination is about 50-80 lx. This is the most common proportion of the key illumination and the ambient illumination.

▲Starbucks, 30 LX ambient illumination, 300 LX desktop illumination, create a relaxed chat atmosphere, computer office is also very sufficient.(The above data do not represent all Starbucks lighting atmosphere.)

Sometimes we need a higher proportion of light in order to catch sight.。

▲For example, our common window models, focus lighting and environmental lighting light ratio usually achieve 30:1, very "eye-catching".

【Common Techniques of Key Lighting】

Close-range lighting, a frequently used method in commercial stores, originates from department stores that need to be brightened on display shelves, and is often found in jewelry stores, jewelry stores, high-end bags, clothing and other high-value-added goods.

▲Low illumination environment lighting to create a relaxed leisure shopping environment, increase customer stay time, thereby promoting sales, commodity lighting to focus on lighting, highlighting the quality of goods.

【What determines the key lighting effects?】

The effect of the key illumination is largely determined by the characteristics of the beam, which are the intensity of the beam, the shape and size of the formed spot, and the amount of scattered light (central light intensity, shape and size, primary and secondary spot).
1. spot

It should be emphasized that there is no good or bad spot, only suitable or inappropriate!

Clean spots are suitable:

Clean spot is not suitable:

                                                                                       Soft and comfortable spots:

Hard and morbid spot:

This kind of spot can often be seen in the interior designer's effect diagram, but it is generally not recommended to use the lamp with such a rigid spot transition.

2. beam angle

Different beam angle effects:

The illumination effect of the lamps at 10 and 40 degrees angles on the desktop only lights up the central area of the desktop on the left, which is strongly contrasted with the surrounding light. In tea chat and leisure places, the soft and comfortable key lighting and environment lighting on the right of the picture are more recommended.

3. Central Light Intensity

Contrast of light spot and illumination value of four kinds of lamps with wall wash effect of 0.1 meters apart from wall surface:

The light intensity is the main reason for the different lighting effects.

Vertical illumination contrast map. The central light intensity is different, the light distribution is different, and the visual effect is quite different.

Finally, to sum up, there is no simple distinction between good and bad in design methods and lamps. What is in line with the characteristics of application sites is "good"!
