The electrodeless lamp is a new generation of green energy-saving lighting source. Because it is a new product, the market penetration rate of the electrodeless lamp is not very high, but it is no exaggeration to describe the current development of the electrodeless lamp with "every day." Domestic companies that produce electrodeless lamps can be divided into two major systems: 2.65MHz high-frequency induction lamps and 250KHz low-frequency induction lamps. Greenley belongs to the former department, and the representatives of the latter department are Shanghai Hongyuan and other enterprises.
Greenle is one of the earliest companies to establish the domestic induction lamp. It is also the first company to push the induction lamp to the market to obtain the first CE certification. It has two national patents. In the absence of the national standards for the electrodeless lamp industry, the company has taken the lead in formulating its own enterprise standard, Production Standard for Induction Lamps. "Really and seriously produce a real green energy-saving long-life induction lamp."
Induction lamp overseas
Foreign electrodeless lamp manufacturers produce Philips, GE, etc. for high-frequency electrodeless lamps, and OSRAM for the production of low-frequency electrodeless lamps. The electrodeless lamp has a small share of the huge world lighting market, but this situation will not last long. Now some countries have already legislated to ban the incandescent lamp as a light source. Energy-saving, environmentally-friendly and long-life induction lamps will surely have a wider city-like "perfect" health light.
The replacement of high-frequency electrodeless lamps as electric light sources has been recognized by more and more people, and has been applied in many fields. Its main features are as follows:
1) Longevity. General incandescent lamps, fluorescent lamps, energy-saving lamps, and other gas discharge lamps have filaments or electrodes, and the sputtering effect of the filament or electrode is an inevitable component that limits the life of the lamp. The high-frequency electrodeless lamp has no electrode, and it is combined with the principle of electromagnetic induction and the principle of fluorescent discharge to emit light, so it does not have an inevitable component for limiting the life. The service life is only determined by the quality grade of the electronic components, the circuit design and the manufacturing process of the foam body, and the service life is generally 50,000 to 100,000 hours;
2) Energy saving. Compared with incandescent lamps, energy saving is about 80%, and the luminous flux of 85W high-frequency electrodeless lamps is roughly equivalent to 450W incandescent light flux;
3) Environmental protection. It uses solid amalgam, even if it breaks, it will not pollute the environment. With more than 99% recoverable rate, it is a true green light source;
4) No strobe. Because of its high frequency of operation, it is considered "no stroboscopic effect at all", does not cause eye fatigue and protects eye health;
5) Good color rendering. The color rendering index is greater than 80, and the light color is soft, showing the natural color of the object being illuminated;
6) The color temperature can be dazzled from 2700OK to 6500OK by the customer according to the needs, and can be made into a color bulb for garden decoration;
7) The ratio of visible light is high. In the emitted light, the proportion of visible light is more than 80%, and the visual effect is good;
8) No need to preheat. It can be started and restarted immediately, and the switch will not have the phenomenon of filament sputtering and the like in the ordinary electrode discharge lamp;
9) Excellent electrical performance. High Power factor, low current harmonics, constant voltage supply, constant light output;
10) Installation adaptability. It can be installed in any orientation without restriction.
Applications are everywhere
Because the high-frequency electrodeless lamp has the above unique advantages, its comprehensive performance can not be compared with any kind of electric light source, it almost brings together the advantages of all different types of electric light source, so it is used for urban lighting floodlighting, landscape Green lighting, factory workshops, school classrooms, libraries, greenhouse vegetable sheds, auditorium halls, conference rooms, large shopping mall ceilings, high-rise buildings, sports tasting tunnels, complex traffic zones (street lights, sign lights, bridge lights), subway stations The dangerous terrain lighting and underwater lights of the railway station are especially suitable for important places where high-risk and difficult lamp replacement and expensive maintenance.

What is Battery Holder?
Battery Holders are devices used to hold and secure batteries in electronic devices. They come in various shapes and sizes, depending on the type and size of the battery they are designed to hold. Battery holders are typically made from plastic or metal materials and feature spring-loaded contacts that connect to the battery terminals to provide power to the device. They are commonly used in electronic devices such as toys, remote controls, flashlights, and other portable devices that require batteries for power. Battery holders are essential components in electronic devices, as they ensure that the batteries are held securely in place and provide a reliable source of power for the device.
Choosing the right Battery Holder.
The kind of battery holder required depends on the below factors:
Size of the batteries being used (AAA, AA, C, D, etc.)
Number of cells being used
Compatibility of the cells being used with the battery holder
Contact and terminal style
Most battery holders are specifically manufactured for a particular type of batteries. However, many battery holders will be compatible with similar batteries with different chemistries. One point to note here is that if a battery holder houses batteries of different chemistries at the same time, the power being delivered will be in line with the weakest battery. Hence, using batteries with the same chemistry is advisable for optimum performance.
Types of Battery Holder Mounts.
The way the battery holder is attached to the cell-powered device is known as the battery holder mount. The different types of battery mounts are:
Panel Mount:
A panel mount battery holder is a separate compartment designed to hold cells. It can be inserted into a cavity in the device that needs power. It can be removed when the batteries need to be changed. They are inserted in the device cavity by screwing in or have Flange Panels.
Slide-In Mount:
In this type of mount, the cells are inserted and removed by sliding in or out. They are the most commonly used mounts and also economical. When a cell is slid in place, it is held by a cover or by the opposing force of two terminals. This type of mount is quite reliable, too.
Chassis Mount:
This type of mount is fixed inside the main body of the device to a surface plate. These mounts come in plastic as well as metal.
PCB Mount:
As the name suggests, the PCB Mount is for when the battery needs to be on a PCB. It has sharp pins around the perimeter which can be used to fix it on a PCB. Usually, they are used to hold coin cells. However, PCB mounts are also made for AAA or AA cells.
Strap & Lead:
They are not entire housing units, but make it possible to attach a battery to an electronic device or holder. It just has a wire and two press studs to hold a cell. Replacement of the cell becomes easy in this method.
Snap-In Mount:
It consists of tensioned metal clips to hold a cell securely in place. The battery is to be pushed into the housing until it snaps in place. This type of mount is best suited for systems prone to shocks and vibrations.
Wire Lead Mount:
This type of mount provides a good level of flexibility in terms of the places where it can be used. It has two wire leads at one end while the other end can be fixed to the device being powered.
Surface Mount:
This type of mount is usually used for coin cells. It lies flat inside the device or within a circuit. It is open-faced and has button terminal contacts.
Through-Hole Surface Mount:
This is best suited to hold batteries where space is a constraint. Instead of being inserted into a cavity in a device, it is fixed on the surface of the device through holes.
Battery holders are often not taken seriously enough when designing systems. However, a reliable battery holder is an important component that contributes to the reliability of the entire system.
