In the last issue, when choosing lamps and lanterns, what did you consider for the owner? , share with you my own summary of the product selection of lamps and lanterns of the six points of the first point: how designers should be based on the preliminary observation of lamps and lanterns, to know the size, appearance, color, light source of lamps and lanterns, material, process, intensity of illumination, color temperature, beam Angle, photosynthetic efficiency, glare and so on factors to distinguish the use of lamps and lanterns is in line with the space requirements.

In this issue we will continue to illustrate the remaining five key points by hand drawing, including the following:
When choosing lamps and lanterns, why to carry on touching to lamps and lanterns, disassemble?
How to think lamps and lanterns all sorts of impersonality and external factor accord with a space?
What important information should be recorded about the luminaire?
Comprehensive analysis and summary: which lamps and lanterns the most appropriate?
2, touch
Why is it necessary to touch it when choosing lamps and lanterns? Because some characteristics of lamps and lanterns are the same as other products, if the workmanship is fine, feel comfortable, generally speaking, the quality of the product basic preference. Therefore, sometimes the general quality of the lamp can be sensed by touch.

3, dismantling
Through the resolution and interpretation of lamps and lanterns, to understand the installation and maintenance of lamps and lanterns, comparing which is more conducive to the future management and maintenance of space.


4, think
Consider different characteristics of lamps and lanterns, contrast whether suitable for the use of functional requirements of the space.

1. Use time and operation cost
Choose suitable lamps and lanterns according to the use time and operation cost of lamps and lanterns.
Because the electricity cost saved by LED is about 85% of that of incandescent lamp, it is better to choose energy-saving lamps for the space such as shopping mall, hotel and office. To turn on light time relatively short demand, wait for a space such as bedroom, kitchen, choose according to cost performance and individual be fond of.
Below, we can understand why we need to consider the use time and operation cost when choosing a lamp from the relation chart of the length of lighting time and operation cost calculated by lighting basic lecture textbook (club) lighting society.

2. Service life and maintenance
Consider maintenance difficult and easy factors, choose long life and short lamps and light sources.
For example: in the shorter space, at the same time easy to replace the light source and maintenance, it is about to consider more quality and cost performance of lamps and lanterns. If it is in a higher space, and even some high-altitude work vehicles are sent for installation and maintenance, it is necessary to consider the life and quality of lamps.

3. Whether the light is adjustable
Determine whether the space should be adjustable light lamps.

4. Materials and lamps
Do not study the relationship between light and material is a bad choice of lamps and lanterns, because the same material, different lamps and lanterns effect is completely different.
For example: the same crack fermenting translucent glass (due to the transparent and reflective nature of the glass), the light coming out of a single 1-watt LED linear lamp will shine partially. The light coming out of the fluorescent lamp (T5) is soft and uniform.

5. Space height and lamps
From the illuminate direction of illuminant, lamps and lanterns can be divided into the type that shine below and the type that shine on, inside indoor, the light that shine on is softer commonly, and shine on appear bright and direct below. When choosing lamps and lanterns so, besides the individual likes, consider the height of smallpox and use space even, such ability won't create oppressive feeling to the space.

5, record
Record different information of lamps for easy comparison, contact and ordering
Record the type of selected lamps for easy ordering and use; Record the price of selected lighting products to ensure the cost is within budget. (tax included); Record the field test and select suitable lamps.

6. Analysis and summary
Finally, comprehensive analysis of the price, performance, quality and other factors of lamps and lanterns, in the comparison to help owners choose the best cost-effective lamps and lanterns.
