Led Sensor Lights Are Not Perfect
The led human body sensor light responds quickly and sensitively and is very power-saving. It is a new generation of energy-saving and environmentally friendly products. It is only at night or in dark areas. When someone appears in the sensing area, the infrared sensing module will start and detect the signal. The signal triggers the delay switch module to turn on the infrared sensor lamp. If the human body continues to move within its range, the LED human body sensor light will always be on at this time. When the person leaves the area, it will be turned off after a delay, and there is no infrared induction signal, and the delay switch will automatically turn off the infrared induction light within the time setting value. Each module returns to the standby state and waits for the next cycle. In this process, there is no need to manually press the switch, and there will be no noise, which is more environmentally friendly.
In addition, the human body sensor-led lights are highly efficient and energy-saving and have stable performance, so they have a longer service life. Human body induction led lights of about 4 watts are comparable to 40-watt energy-saving bulbs.
Two Options For Sensor Lighting
Microwave vs PIR Sensor, Which Should You Choose? For outdoor floodlights with sensors, both are more common types, and the final choice depends on these factors.
To detect motion, microwave sensors don't need a precise line of sight. Therefore, they are more suitable for oddly shaped rooms and areas with many obstacles. They also don't rely on thermal signals, making them more reliable in hot environments where PIR sensors may not be effective. Microwave sensors are also significantly more sensitive, making them ideal for situations where very little motion must be detected.
Advanced controls can also allow precise settings for a parking lot or warehouse lighting layouts. In these cases, advanced control and precise sensing are required, making motion sensors a viable option.
On the other hand, PIR sensor lights are much more efficient for garden and home protection. However, they may not be suitable for placement in very open areas.
PIR sensor lights are often the best choice for outdoor security lighting. Because they only detect motion from living bodies, they are less likely to cause false positives. Microwave sensors, on the other hand, can be configured to only detect the movement of objects the size of a human body, although this is usually done before the sensor is put into the light.
Portable Work Light And Work Light With Tripod
As a portable rechargeable led flood light, the work light of this structure adopts a bidirectional rotating shaft design, and the lighting angle is larger. Its radiator with USB on the back is designed as a port for charging the phone. Because of its ultra-thin product design, it is easy to carry. The size of this product is 298mm long, 246mm wide, and 3.4mm thick, and the weight is between 15.1/16.8kg. As long as it is AC220-240V~ 50/60Hz, you do not need the light source of this LED light because it has 2835 SMD, which can guarantee the Light source range.
What is the price of floodlights related to?
First of all, when purchasing this type of LED floodlights, pay attention to its antistatic ability.
Secondly, we should also pay attention to its leakage current.
In addition, when selecting floodlights, factors such as luminous angle, wafer, colloid, etc., all affect the price of floodlights to a certain extent.
How about Floodlights
Floodlights are rarely used in home decoration. They are generally used in garden decoration or shed lighting. Outdoor LED floodlights produce highly diffused, non-directional light instead of clear beams. The resulting shadows are soft and transparent, and when used for object lighting, the lighting decays much more slowly than with spotlights, and even some floodlights, which decay very slowly, look like a light source that does not produce shadows. There are many brands of floodlights on the market today, and they vary in brightness and number of lamp beads. Generally speaking, the more lamp beads and the greater the brightness, the more expensive it is.

Why Does The Led Light Become Less Bright With More Use
It is a very common phenomenon that LED lights become dimmer as they are used. In addition to light decay, the reasons for dimming LED lights are nothing more than the following two points.
Theoretically speaking, as long as the parameters of the driver match the lamp bead board, the power supply can be continuously supplied and used normally. The inside of the driver is more complicated. The failure of any device (such as capacitor, rectifier, etc.) may cause the output voltage to change, which in turn causes the lamp to dim. Driver damage is one of the most common faults in LED lamps, which can usually be solved by replacing the driver.
The LED itself is composed of lamp beads one by one. If one or part of them does not light up, it will inevitably make the whole lamp dim. The lamp beads are generally connected in series and then in parallel - so if a certain lamp bead is burned, it may cause a batch of lamp beads not to light up. There are obvious black spots on the surface of the burned lamp bead, find it, connect a wire to its back, and short-circuit it; or replace it with a new lamp bead, all can solve the problem.
Solving The Heat Dissipation Problem of Led Products
There are three main ways to reduce the heat accumulation of LEDs. One is to improve the characteristics of the die.The second is the Die Bonding method, which is changed from Wire Bonding to Flip-Chip .The third is that the packaging substrate adopts materials with high thermal conductivity such as aluminum oxide, aluminum nitride, beryllium oxide and boron nitride, which are matched with the thermal expansion coefficient of the LED, thereby reducing the total thermal resistance of the entire heat dissipation substrate.
The Benefits of Led Floodlight Design
Under the same installation conditions, the 100W LED floodlight can reach the same level as the 250W metal halide lamp,100W LED floodlight can replace the 250W metal halide lamp.

Floodlights are one of the most widely used light sources in rendering. In a scene, multiple floodlights can be used to coordinate the effect for better results. This is the best way to illuminate objects from specific points in all directions, and use it to simulate light bulbs and candles.floodlights can be placed anywhere in the scene. For example, it can be placed outside the scope of the camera or inside the object. It is common to use many floodlights of different colors in a scene. These floodlights can cast darkness and blend into the model. Floodlights are easy to predict due to their large lighting range, and there are many auxiliary uses for this light. For example, if a flood light is placed close to the surface of an object, it will sit on the surface to produce a bright light.
Why Can Led Floodlights Be Used In Major Lighting Places
Why Can Led Floodlights Be Used In Major Lighting Places
LED floodlights can be controlled via a built-in microchip. Renovation engineering applications, they can make seconds without a controller. They can achieve dynamic effects such as gradients, jumps, color flashes, random flashes, gradients, etc. Control, realize the effect of chasing, scanning and so on.
LED light use a low-voltage power supply, and the power supply voltage is between 6-24V, depending on the product. It's a much safer power source than using a high-quality power source. Compared with incandescent lamps with the same light efficiency, the energy consumption is reduced by 80%, and there are three types of LED light sources in the application of color.
the light source of the led light has three colors
