What are the types of LED spotlights

1. Lower the lighting. It can be installed on the ceiling, above the head of the bed, in the cabinet, and can also be hung, floor to floor, or in the air. The characteristic of bottom lighting is that the light source provides local illumination, scattering freely from top to bottom, and the light source is enclosed in the lampshade. Can be installed in porch, living room, bedroom, etc. 2. Track the spotlight. It is mostly made of metal spray molding or ceramic materials, with colors such as pure white, beige, light gray, gold, silver, black, etc; The shape is long and round, with varying sizes. The beam of light projected by a spotlight can be concentrated on a painting, a sculpture, a potted flower, an exquisite decoration, etc. It can also shine on the back of the swivel chair where the room owner sits, creating a colorful effect. And magical light and shadow effects. Can be used in the living room, porch, bedroom, or study. There can be one or more spotlights, and the shape and color of the spotlights should be as coordinated as possible with the overall design of the room. The guide rail is installed 15 to 30 centimeters below the ceiling, and can also be installed at the corners of the ceiling against the wall. 3. Cold light spotlights. Cold light does not generate thermal radiation on the illuminated object. Anti glare, accurate light distribution and projection angle of lighting fixtures. High light efficiency, energy saving and electricity saving. Long lifespan, if not lit within one year of normal use, the lamp can be replaced with a new one for free. No flicker, which prevents fatigue in the eyes. Good color rendering, able to showcase the meticulous craftsmanship and true color of the product. Exquisite design, low-voltage power supply, safe, energy-saving, and efficient.

Working principle of solar LED street lights

Solar LED lamps mainly consist of two parts: solar photovoltaic cells and semiconductor lighting sources, forming an efficient lighting system through the combination of DC and low-voltage. The working principle of solar LED lamps is to use the principle of photovoltaic effect to make solar cells. During the day, solar panels receive solar radiation energy and convert it into electrical energy output, which is stored in the battery through a charging and discharging controller. At night, when the illumination gradually decreases to around 10lux, the open circuit voltage of the solar panel is about 4.5V. The charging and discharging controller detects this voltage value and acts, causing the battery to discharge the lamp holder. The working principle of solar LED lights is the simplest: solar panels absorb and convert solar energy into electrical energy for storage, which is then stored in the battery for use at night. The batteries are divided into lead-acid batteries and colloidal batteries, and the main function of the solar LED street lamp charging and discharging controller is to protect the batteries. During the day, sunlight shines on solar panels, and the battery components of solar LED street lights generate a certain level of DC voltage, converting light energy into electrical energy, which is then transmitted to the controller. The transmitted electrical energy is then transferred to the battery for storage through the overcharging protection of the intelligent controller. At night, when there is no sunlight, the solar LED street light components cannot receive light energy. At this point, the solar LED street light intelligent controller will automatically turn on the control device, and the battery will supply power to the LED light source through the over discharge protection device of the intelligent controller. Enable solar LED street lights to emit sufficient light to illuminate. Solar LED street lights work repeatedly every day.

Which is more energy-efficient, LED light or energy-saving light

LED lights and energy-saving lights are currently two common types of lighting fixtures in our daily lives. They are commonly used lighting fixtures in our daily lives. Although there are still many people who choose these two lights, they will also consider saving money. The problem is that there are many appliances, and only energy-saving can make people more like them. So which one is more energy-efficient, LED lights or energy-saving lights? Firstly, it must be emphasized that LED bulbs are more energy-efficient than energy-saving lamps, which is the most common reason for most people. I know or have heard of it, but there are still many people who doubt it. After all, they haven't calculated where to save electricity yet. Due to the different emission principles of energy-saving lamps and LEDs, their emission efficiency also varies. The luminous efficiency of halogen energy-saving lamps is only 30-40lm/W, and the luminous efficiency of tricolor energy-saving lamps is higher than that of halogen energy-saving lamps. About 40-60lm/W (different brands of products have different quality and lighting effects, with Philips energy-saving lights having an efficiency of about 60lm/W). But the luminous efficiency of LED is much higher than that of energy-saving lamps, and the current technological level generally reaches 90-100lm/W. Therefore, in essence, the brightness generated by 1W LED requires at least about 2W energy-saving lamps to achieve similar brightness. However, the actual brightness is influenced by many factors. The most direct factor is temperature. Light attenuation: energy-saving lamps generate bright heat, while LEDs are cold light sources that generate much less heat than energy-saving lamps, so the light attenuation of LEDs is smaller than that of energy-saving lamps; There are many buyers and users who know that LEDs are more energy-efficient than energy-saving lights, and lights are more energy-efficient. However, I feel that LEDs are more expensive than energy-saving lights, and the saved electricity is not enough to make up for the extra money spent on buying lights. Therefore, I have decided to continue buying cheaper energy-saving lights.
