As of 01.09.2018, the sale of low-voltage halogen lamps and HV lamps is prohibited. We provide you with the most important background information.
The European Union (EU) has determined that energy consumption should be gradually reduced, thereby protecting the environment. And the ban on the use of mercury in luminaires is designed to provide greater safety.
Consequently, the LED is becoming a mandatory must-have across Europe. Nevertheless, the costs are often amortized after about 3 years and the lifespan is usually far from finished.
But now to the background. The EU introduced the so-called light bulb ban in 2009. Many remember the subsequent almost panicked hamster purchases of incandescent bulbs. As a result, the development and sale of LED and fluorescent tubes has been massively advanced. The ban was phased in. In this way, the EU is actively trying to reduce energy consumption in the private and commercial sectors. As with the “incandescent bulb ban” in 2009, residual stocks may continue to be sold and used. Since 2016, the sales ban has been extended to many fluorescent tubes. These are to be banned outright under the “Ecodesign Directive” from 2020. The reason here is the extremely toxic mercury. As the demand for the efficiency of the light bulb increases at the same time, from 2020 only T5 fluorescent tubes, most efficient halogen metal vapour lamps and low-pressure sodium vapour lamps and, of course, LED (1) will be available to us.
As of 01.09.2018, the sale of all halogen and incandescent bulbs is prohibited, the efficiency of which is worse than Class B. Exceptions are clear halogen lights with R7s or G9 plinths. In addition, the regulation also lists, among other things, the following exceptions:
The requirements of this regulation do not apply to the following household and special lamps
Lamps with bundled light
Lamps with a stream of light below 60 lumens or over 12,000 lumens
Fluorescent lamps without a built-in ballasts
High-pressure discharge lamps
It should be noted that fluorescent tubes must be collected and disposed of correctly when retrofitting to LED. Because of the mercury content, fluorescent tubes are not allowed into household waste or glass containers. Delivery of old fluorescent tubes is possible in the following places:
Retailers must take this product back, but of course the previous purchase must be substantiated
Supermarkets and drugstores often offer collection points for light bulbs
Local recyclable yard
Should a fluorescent tube break, caution should be maintained in any case. If a fluorescent tube is broken, we recommend the immediate ventilation of the room, absolutely avoid skin contact, wear gloves at the removal, instead of using the hand sweep a piece of cardboard to bring together, pick up other splinters with damp cloth and absorb everything Leave to be professionally recycled in a sealable vessel at the recyclable yard. The gloves used, heavily soiled clothing, used cloths, etc. should also be fed to the garbage.
Definition:
EU Directive: Individual member states can decide for themselves how to implement EU directives. So there is some room for manoeuvre in the implementation.
EU regulation: They are directly effective and binding on each Member State and must be implemented.
With SVETOCH’s LED components, luminaires with high-performance leather can be created quickly and easily for industrial use. We are pleased to present this with a video. Enjoy rebuilding!
High-power light emitting diodes (high-power LEDs) can be 350 milliwatts or more strong in a single LED. Most of the energy in an LED is converted into heat rather than light (about 70% heat and 30% light). If this heat cannot be dissipated, the LEDs glow at very high temperatures. This not only lowers the efficiency, but also shortens the lifespan of the LED. Therefore, the thermal management of high-power LEDs is an essential area of research and development. It is necessary to limit the Junction Temperature of a value that ensures the desired LED life.
Heat transfer
To maintain a low lock layer temperature that maintains the high power of an LED, any possibility of heat removal from LEDs should be considered. Heat conduction (reduction), heat removal by air (convection) and radiation are the three possibilities for heat transfer. Typically, LEDs are encapsulated in a transparent resin, which is a bad heat conductor. Almost all of the heat generated is passed through the back of the chip. Heat is generated by the p-n transition by electrical energy that has not been converted into useful light. It reaches the soldering point via a long distance from the connection point, the soldering point to the circuit board and the circuit board to the heat sink and is then directed to the atmosphere of the external environment.
The barrier layer temperature is lower if the thermal impedance is smaller or the ambient temperature is lower. To maximize the usable ambient temperature range for a given loss performance, the total heat resistance from the connection point to the environment must be minimized.
Heat resistance values vary widely depending on the material and adjacent components. For example, RJC ( thermal resistance barrier layer to housing) ranges from 2.6 ° C/W to 18 ° C/W depending on the LED manufacturer. The thermal resistance of the thermal conduction material (also TIM: Thermal Interface material) also varies depending on the type of material selected. Guying TIMs are epoxy, thermal paste, adhesive and lot. High-power LEDs are often mounted on metal core circuit boards (MCPCBs) attached to a radiator. Heat passed through the metallic module plate and the heat-conducting radiator is then dissipated by convection and radiation. In addition to the design and design of the cooling body, the surface evenness and quality of each component, the pressure, the contact surface, the type of thermal conduction material and its thickness are. These are parameters for heat resistance or cooling of the LED through heat removal.
Passive cooling
Factors for passive cooling for efficient heat management of high-power LEDs are:
Thermal conductor
Thermal conductor is normally used to connect LED to the board and the board to the radiator. The use of a thermal conductor can further optimize the heat output.
Heat sink
Heat sinks contribute significantly to the removal of heat. It functions as a conductor that directs heat from the LED source to the outer medium. Heat sinks can deduce energy in three ways: Heat conduction (reduction: Heat transfer within or from one solid to another), convection (heat transfer from one solid to a moving fluid, for most LED applications is The fluid the ambient air) or radiation (heat transfer of two bodies of different surface temperatures through heat radiation).
Material:
The thermal conductivity of the material that makes up the radiator directly affects the loss performance of the thermal conduction. Normally, aluminium is used because of the very good value for money. In the case of flat coolers, copper is often used, despite the high purchase price. New materials include thermoplastics, which are used when heat dissipation requirements are lower than normal (e.g. often in home requirements) or complex shapes in the spray casting process make sense. Graphite solutions often have a more effective heat transfer (not thermal conduction) than copper at a lower weight than aluminium. Graphite is considered an exotic cooling solution and is more expensive to produce. Heat pipes can also be added to aluminum or copper coolers to reduce dispersal resistance.
Form:
The heat transfer takes place on the surface of the cooler. Therefore, heat sinks should be designed to have a large surface area. This can be achieved by using a large number of fine ribs or by enlarging the radiator itself. Although a larger surface area leads to better cooling performance, there must be enough space between the ribs to create a considerable temperature difference between the cooling rib and the ambient air. If the ribs are too close to each other, the air in between can have almost the same temperature as the ribs, so no heat transfer takes place. As a result, more cooling ribs do not necessarily lead to more cooling power.
Texture:
Heat radiation of coolers is a function of surface texture, especially at higher temperatures. A painted surface has a greater emission level than a bright, unvarnished surface. The effect is most notable for shallow coolers, where about a third of heat is dissipated by radiation. In addition, an optimal flat contact surface allows the use of a thinner thermal conduction paste, which reduces the heat resistance between the heat sink and the LED source. On the other hand, anodising or etching also reduces thermal resistance.
Installation method:
Cooling body fasteners with screws or feathers are often better than conventional clips, thermal conductor or tape. For heat transfer between LED sources over 15 watts and LED coolers, it is recommended to use a high-heat conducting interface material (TIM) that has a heat resistance above the interface of less than 0.2 K/W. Currently, the most common method used is a phase change material that is applied at room temperature in the form of a solid pillow, but then converts into a thick gelatinous liquid as soon as it rises above 45 ºC.
Heat pipes and steam chambers
Heat pipes and steam chambers have passive effects and their thermal conductivity capabilities are very effective from 10,000 to 100,000 W/mK. They offer the following advantages in LED heat management:
Transports heat to another radiator with minimal temperature drop
Isothermizes heat control through natural convection, increasing efficiency and reducing its size. It is a case known in which the addition of five heat pipes reduced the heat conflux mass by 34% from 4.4 kg to 2.9 kg.
The high heat flow directly under an LED efficiently into a lower heat flow, which can be dissipated more easily.
PCB (tight: Pressed circuit board)
MCPCB:
MCPPCB (Metal Core PCB) are boards that contain a base metal material for heat distribution as an integral part of the circuit board. The metal core usually consists of an aluminium alloy. MCPCB has the advantage of a dielectric polymer layer with a high thermal conductivity.
Separation:
Separating the LED driver circuit from the LED board prevents the heat generated by the driver from increasing the LED lock layer temperature.
Platinum coating
Additive process:
On the PCBs, conductive substances are applied to the carrier material during the production process for the creation of conductive structural surface. The conductor is only applied to the predetermined conductor’s track image. In contrast, this is etched away in the subtractive process. Basically, there is a direct connection to the aluminium radiator; For example, no additional material for the thermal connection is required for the circuit. This reduces the heat-conducting layers and heat surface. Processing steps, types of materials and material quantities are reduced.
Aluminium ladder plates (also known as IMS circuit boards for Insulated Metal Substrates)-It increases thermal connection and provides a high dielectric penetration voltage. Materials tolerate heat up to 600 ° C. The circuits are directly attached to aluminium substrates, so no thermal conduction materials are required. The improved thermal connection can reduce the lock layer temperature of the LED by up to 10 ° C. This allows the developer to reduce the number of LEDs required on a board by increasing performance for each LED. It can also reduce the size of the substrate to meet dimensional limitations. It has been proven that a reduction in the transition temperature greatly increases the lifespan of the LED.
Form factor
Flip chip:
The LED chip is mounted with the front down on the mount, which is usually made of silicon or ceramic and is used as a heat distributor and carrier substrate. The flip-chip connection can be eutectic, leaded, unleaded or gold stub. The primary light source comes from the back of the LED chip. A reflective layer is usually built in between the light emitter and the soldering sites to reflect the light emitted downwards. Several companies use flip-chip cases for their high-power LED, reducing LED thermal durability by about 60%. At the same time, thermal reliability will be maintained.

Light + Building was the name of it and was the World Fair for Light and Building Technology. Today it came to an end. 15 of their kind is stretched around the whole world ball. The largest of them could be visited in Frankfurt am Main this week. Huge 16 areas with over 10 halls. 2,714 exhibitors from 55 countries presented their products on the topic of light and building technology and were visited by more than 220,000 trade visitors from 177 countries.
We, too, were there almost every day, strolling from booth to stand and from hall to hall. Half of the visitors and exhibitors were from abroad and the same language was not always spoken. Communication was exciting and took place more than once with your hands and feet.
Of course, we have constantly compared our products with those of others.
Our great strength of maximum light output due to optimal heat dissipation hardly found any competition there. There was industrial lighting with high-power LEDs. However, if we noticed one or the other competing product, it was clear that this is too expensive for the customer. The look of the lights often pleased. But we had to keep wondering who should pay those prices for it. This cannot be profitable for any company.
So our conclusion is that we spent beautiful long days at the Light + Building fair. We’ve seen a lot of novelties and met a lot of great people. We are very much looking forward to working together. But an offer like the one we offer, unfortunately, didn’t occur to us there or thankfully. We will be a guest again in 2020 and look forward to seeing you again!
It’s done! SVETOCH is online with its page. We are very happy with our performance and radiate to the future full of joy and hope. Seemingly infinite questions had to be answered. Many stones were put in our way. One unexpected challenge after another had to be contested. Now we have taken the step forward and the question of the login name and password no longer exists. SVETOCH is online, inviting everyone to visit and hoping to meet every customer’s demand with good quality, tailor-made solutions, lots of light and low prices!
We look forward to the future and above all we look forward to working with you!
