- The lamp bead is a very important accessory in the LED lamp. It determines the angle and efficiency of the LED lamp. At present, the single crystal lamp bead is more common in the market, which is a whole piece of crystal. The price of the double crystal lamp bead is relatively High, but the performance will be much better than single crystal.
- According to experts, the color rendering of LED lamps can be determined by the authenticity of an ordinary object under the light. Generally, the higher the authenticity, the better the color rendering of the LED lamp. The owner chooses , you can test it directly.
- As mentioned above, the brightness of LED lights is divided into several levels. When the owner chooses, it should be determined according to the size of the room, because whether the light is too strong or too weak, it will have a great impact on people’s vision. Effects, long-term use can lead to poor vision.
- The lampshade is an important factor to determine whether the LED light source is bright or dazzling, and it is also a key point of decoration. When purchasing, it is necessary to look beautiful. At the same time, it is necessary to look at the light transmittance and light and shadow effects of the lampshade. It is recommended to choose light transmission Good rate, uniform luminescence.
What is the reason for the flashing of led garden lights?
It may be that the lamp bead does not match the drive power supply, and there is no way to withstand the corresponding current, so the light will flicker, and it is necessary to replace a lamp that matches the drive power supply.
- It is possible that the drive power supply is damaged. After a period of use, it will inevitably be damaged, so a new drive power supply needs to be replaced.
- It may be that the heat dissipation of the lamp is not enough, and the drive power supply has an over-temperature protection function. In this case, flickering will appear, so it is necessary to replace the lamp with better heat dissipation performance.
- There may be water entering the lamp. Once water enters, the lamp beads and driving power inside may be damaged, and it will also cause flickering or no light. It needs to be replaced with a new one. The lamp beads and driving power.
It needs to be dealt with in combination with specific reasons, and the method of treatment is relatively simple.
What should I do if the led garden lamp beads are broken?
After the LED light is turned on, some of the lamp beads do not light up, basically it can be judged that the lamp beads are damaged. The damaged lamp beads can generally be seen with the naked eye-there is a black spot on the surface of the lamp bead, which proves that it has been burned. Sometimes the lamp beads are first connected in series and then in parallel, so the loss of a certain lamp bead will cause a piece of lamp bead to not light up.
- A small amount of damage
If only one or two lamp beads are broken, we can repair them in two ways:
- Find the broken lamp bead, connect the metal at both ends of it with a wire, and short-circuit it. The effect of this is that most of the lamp beads can be turned on normally, only a few broken ones are not lit, which has little effect on the overall brightness.
- If your hands-on ability is relatively strong, you can go online to buy the same type of lamp beads (10 yuan for a large pack), and replace them by yourself——heat the old lamp beads with an electric soldering iron (blow with a hair dryer for a while) , until the glue on the back of the old lamp bead melts, use tweezers to remove the old lamp bead (don’t use your hands, it’s too hot). At the same time, install the new lamp bead while it is hot (pay attention to the positive and negative poles), and you’re done!
Two, a lot of damage
If a large number of lamp beads are damaged, it is recommended to replace the entire lamp bead board. Lamp bead boards are also available online. Pay attention to three points when purchasing: 1. Measure the size of your own lamps; 2. Be optimistic about the appearance of the lamp bead board and the connector of the starter (explain later); 3. Remember the output of the starter Power range (explained later).
These three points of the new lamp bead board must be the same as the old lamp bead board – it is very simple to replace the lamp bead board, the old lamp bead board is fixed on the lamp holder with screws, just take it off. The new lamp bead boards are all fixed with magnets. When replacing, just remove the new lamp bead boards and connect them to the connector of the starter.
Most of the failures of LED lights are caused by the starter. If the lights do not light up at all, or the overall failure of the lights such as flickering after the lights are turned on, the starter is probably broken.
The starter can’t be repaired, it has to be replaced with a new one. Fortunately, the new starter is not expensive. There are three things to keep in mind when purchasing a new starter:
- Pay attention to the appearance of the connector
- Remember whether your lamp can change color and how many colors it can change. The new starter must have the same amount of discoloration as the old starter.
- Remember the output power range of the starter – a range will be marked on the starter, as long as the power of the lamp bead board is within the specified range.
How about solar led garden lights
Solar garden lights mainly rely on solar panels to generate electricity. The solar controller stores the electric energy in the battery for use at night, without manual control, light control + time control, and the photoelectric conversion rate of solar panels reaches 16% under good lighting conditions. %, service life up to 30 years;
The solar street lamp controller adopts the integrated design of light control + time control, waterproof and cold protection, which greatly reduces the failure rate; the light source adopts a special LED light source for solar garden lamps, with high luminous efficiency and an actual service life of more than 50,000 hours; the lamp body is welded with Q235 high-quality steel The surface is galvanized and sprayed with plastic, anti-corrosion treatment, and the wind resistance is greater than 9.
1 super long life
The semiconductor chip emits light, has no filament, no glass bubble, is not afraid of vibration, is not easy to break, and has a service life of up to 50,000 hours (the service life of ordinary incandescent lamps is only 1,000 hours, and the service life of ordinary energy-saving lamps is only 8,000 hours).
2 light health
The light does not contain ultraviolet rays and infrared rays, and does not produce radiation (common light contains ultraviolet rays and infrared rays).
3 green environmental protection
It does not contain harmful elements such as mercury and xenon, which is conducive to recycling and utilization, and will not generate electromagnetic interference (common lamps contain elements such as mercury and lead, and electronic ballasts in energy-saving lamps will generate electromagnetic interference).
4 High light efficiency, low heat generation
90% of the electrical energy is converted into visible light (80% of the electrical energy of ordinary incandescent lamps is converted into heat energy, and only 20% of the electrical energy is converted into light energy).
5 protect eyesight
DC drive, no stroboscopic (ordinary lights are AC driven, it will inevitably produce stroboscopic).
Solar energy can be automatically turned on and off according to the level of light and darkness throughout the year, regardless of spring, summer, autumn and winter. All charging, discharging, opening and closing are fully intelligent and automated. With the increase in electricity costs, social awareness of environmental protection and energy conservation has increased. As well as the support of national policies for the energy-saving industry, solar garden lights will inevitably replace traditional lamps and become the mainstream of the market
