With the advent of non-replaceable light sources, especially the large number of luminaires that have used non-replaceable LED modules in recent years, the concept of the original traditional, single replaceable light source is facing an impact and needs to be revised. The light source used in the luminaire is divided into a replaceable light source and an irreplaceable light source. A form of luminaire in which a non-replaceable light source has appeared. The replacement of the light source in the original standard mentioned in the original standard, with the emergence of the classification of the two forms of light source, needs to be refined to make it clearer. The next edition of the standard, Version 8 IEC 60598-1, Lamps Part 1: General Requirements and Tests, will be modified as follows:
First, define the concept of light source, replaceable light source and non-replaceable light source
Version 8 of IEC 60598-1 adds the concept of light sources, replaceable light sources and non-replaceable light sources. Otherwise, for luminaire products that use non-replaceable LED modules, there will be misleading in the category of luminaire products, thinking that it is neither a luminaire nor a light source. It is a new category of lighting products, called the so-called LED lighting products or The name of the semiconductor lighting products, so there is no standard for LED lighting products or semiconductor lighting products. Various standards, technical specifications or technical requirements are constantly being developed throughout the country, and the situation of your debut is on the scene. The 8th edition of IEC 60598-1 defines the concept of light source, replaceable light source and non-replaceable light source, which helps to clarify the basis of LED luminaire standards, and helps LED luminaire products to be tested in accordance with international standards and contribute to China's lighting. The healthy development of the electrical industry. It can be seen that the three light source-related definitions added in the eighth edition of IEC 60598-1 have great significance for the development direction of China's LED lighting products.
A light source is defined as a lamp that provides a lamp head that conforms to the IEC 60061 or that is used in a luminaire or integrated into a luminaire to produce visible light radiation (LED) modules or other light sources.
An alternative light source is defined as a lamp that provides a lamp head in accordance with IEC 60061, or a light source intended to be connected by a terminal block, connector or the like, and is intended to be replaced during normal use or maintenance of the lamp. Note 1: Examples of replaceable light sources are all lamps with a cap. Note 2: Built-in LED modules in accordance with IEC 62031 are considered as alternative light sources.
An irreplaceable light source is defined as a light source that is not replaceable by a luminaire, or that cannot be replaced by a light source, or that is enclosed in a casing that is fixed by a screw or similar fixture and that is intended to be opened only once.
2. The manufacturer of the lamp that cannot replace the light source has the obligation to inform the user.
The life of a luminaire with a replaceable light source depends on the control of the light, not on the light source, since the light source is replaceable, and if the light source is broken, the luminaire can continue to be used after the light source is replaced. The life of a lamp that cannot replace a light source depends on the control device and the light source of the lamp, and to some extent depends on the life of the light source. If the light source reaches the end of its life, the lamp that cannot replace the light source will not be used and will be discarded.
Manufacturers of luminaires that are not replaceable light sources have an obligation to inform the user. For luminaires with non-replaceable light sources, the instructions should include the following information: "The light source of this luminaire is not replaceable; once the light source needs to be replaced (if the light source is at the end of its life), the entire luminaire should be replaced."
Third, the structure
1. In order to avoid the use of conventional lamp heads, the conventional lamp does not require a lampholder to add a new paragraph to the lampholder requirements of the structure as follows: use a lamp intended to be connected to a lamp holder or connector in accordance with IEC 60061, without the associated lamp holder or connection It is not allowed to make electrical connections in other ways (such as by soldering wires directly to the pins).
2. The structure of the luminaire with a new non-replaceable light source is required to replace and/or be close to live parts without damaging the luminaire or its components.
Compliance is checked by the following tests:
All luminaire components close to the light source should be opened or removed. Parts that may be opened by hand or with a tool should be removed. Access to the opening requires destruction of any component, sealed, glued or embedded obstacles that do not open. Obstructions that are permanently deformed when opened and that do not allow the luminaire to be reinstalled in the correct manner, do not open.
Parts that are designed to be screwed and that are only shaped once and that cannot be unscrewed with a tool are not opened.
After removing all parts, you should not touch live parts. The accessibility of live parts shall be checked using test fingers and test methods specified in Chapter 8 of this standard.
Fourth, make changes to the light source to replace the light, emphasizing the replacement of the light of the replaceable light source
The clauses specifically related to the amendments are 4.7.2, 7.2.1 and 8.2.1, which have requirements for opening the luminaire to replace the light source. When the luminaire must be turned on for the test, it is more clear to replace the original "light source" with the "replaceable light source".
1. Structure 1.7.2 The first paragraph is modified as follows: The power supply terminal should be positioned or protected so that there is no danger of contact between live parts and metal parts even if one of the stranded conductors is disconnected from the terminal. The metal part refers to a metal part that can be accessed by a standard test finger when the lamp is completely assembled or used when the lamp is replaced or the lamp or the starter of the replaceable light source is replaced.
2. Grounding Regulations 7.2.1 Paragraph 1 is amended as follows: Class I luminaires, metal parts accessible during installation, or replacement of replaceable light sources or replaceable actuators or cleaning, and when insulation fails It may become a live metal part that should be permanently and reliably connected to a ground terminal or ground contact.
3. Protection against electric shock 8.2.1 Paragraph 1 is amended as follows: The luminaire shall be manufactured so that the luminaire must be turned on when the luminaire is installed and wired as in normal use and when the lamp or (replaceable) starter for replacing the alternative light source is turned on, It is not hand-operated and its live parts are inaccessible. Basic insulation parts...

WHAT MAKE UP AN EXCELLENT LED GROW LIGHT ?
1.PPFD Value : PPFD is Photosynthetic Photon Flux Density. When you choose a plant light, you should compare the PPFD values of different plant lights. The larger the value, the better the growth of the plant.
2.Actual Power: Because the actual power of the plant light always varies with different conditions, all Amazon sellers use the rated power to describe the power of the product because the rated power is constant. When you pick a LED grow light, the rated power of the plant light is a reference, and more importantly is the actual power.
3.Core Coverage: In addition to the above two, when you choose a plant light, you also need to compare the cover area of different plant lights, of course, the size of the core coverage area. In general, in germination stage, you can hang the plant light higher and the cover area is larger. In flowering stage you can hang the plant light lower and the cover area is smaller because the plant needs more light at this stage. You have to compare different coverage areas to choose the plant light that suits you.
