　　umbrella quality

　　The quality of the ribs:

　　determines the quality of an umbrella. The ribs are mainly divided into fiber ribs and steel ribs. Fiber rib umbrellas are more wind-resistant and rust-proof. The number of ribs is divided into 8 ribs, 10 ribs, 16 ribs, etc. The more the better.

　　The density of the umbrella cloth:

　　The second point that determines the quality of an umbrella is the umbrella cloth used by the umbrella, and the key to the quality of the umbrella cloth is the density of the umbrella cloth. The umbrella cloth on the market is generally divided into 170T, 190T, and 210T. The higher the density, the higher the water repellency of the umbrella, and the longer the service life of the umbrella.

　　Straight-pole umbrellas are more durable:

　　Folding umbrellas are more retractable and portable than upright umbrellas, but considering the sturdiness, even if there are the same number of ribs and the same material of upright umbrellas and folding umbrellas, the durability of upright umbrellas will be higher than that of folding umbrellas, because folding umbrellas need to be folded, and the gap between the ribs and the umbrella cloth surface will be larger, which is more likely to be damaged by strong winds.

　　Turn the top of the umbrella to see the tightness:

　　Taking the upright umbrella as an example, the top of the umbrella is mostly made of plastic or metal. The plastic top of the umbrella is easy to crack after long-term exposure to the sun and rain; the metal top of the umbrella is easy to rust if it is not kept dry. When purchasing, you can use your fingers to slightly turn it. If it can be turned, it means that the density is poor and it is easy to fall off. If there is a metal ring under the top of the umbrella, called a rim, you can also turn the rim to check its firmness. Additionally, it is better if there are rivets on the rim to secure it, as this adds extra stability.

　　Turn the umbrella to test the handle:

　　Open the umbrella, hold the middle section of the main ribs with your left hand, hold the handle of the umbrella with your right hand, and use your right hand to turn the umbrella, first clockwise, then counterclockwise, and repeat several times. In this way, you can know whether the handle and the ribs are firm.

　　Folding and pulling trial:

　　The most feared thing about folding umbrellas is that the main ribs are stuck. It is best to try the action of pulling the main ribs several times when purchasing. If it feels smooth when pulling, the quality of the umbrella is good. If it feels stuck, don¨t buy it.

　　I don’t know when it started, but when I searched for international express delivery on a certain book, I saw all the ads holding signs saying “XX from China, 10KG = 38 yuan, regardless of whether it is ordinary or not.”As a representative of the industry, freight forwarder china to usa It is necessary to set a certain example for peers and lead the way in product quality. https://www.freeseaship.com/

　　On average, this means less than two yuan per pound. Do you have any idea whether you can get this price?

　　0.jpg

　　Let’s think about it first. This price is impossible even in China, let alone international express delivery. Is it possible?

　　Secondly, families should know that international express delivery does not distinguish between sensitive goods and general goods.

　　In terms of cost alone, sensitive goods are higher than general goods. The fear is that you will be warmly received at the beginning, but then turn your back on them.

　　00.jpg

　　Then there may be such a situation: you don’t find such a shipping company, but you still fall into the trap. How should you avoid these pitfalls?

　　Family members have done their homework, and the key points are as follows! !

　　international shipping

　　1. Check the business license

　　Whether a company is operating in compliance can be determined by checking the company’s qualification certificates, such as whether it has international freight forwarding qualifications and other permissions.

　　2. Be wary of ultra-low prices

　　International express delivery costs cannot be much lower than the market price. Too low quotes often hide traps

　　There may be other charges, such as packaging fees, photo fees, etc., and there may even be extremely expensive additional weight prices, which are more expensive than the generally advertised 60 yuan per kg. Don’t try it at the cost of losing more for a small price. It’s not worth it.

　　3. Whether the price is clearly marked

　　See whether the fee is charged according to the quotation form. Many companies often start charging various fees after the user places an order to the warehouse: handling fees, material fees, labor fees, etc.

　　4. Is there an official website system?

　　Generally, regular shipping companies have their own official website systems. Global Express not only has its own official website but also has a mini program. All package information can be checked, and there will also be exclusive customer service to follow up.

　　5. Pay attention to surcharges

　　Pay special attention to surcharges, which may be more expensive than the freight in a few minutes! You must ask clearly what surcharges there are before placing an order.

　　6. Keep evidence

　　When communicating with the shipping company, keep chat records, quotations, contracts and other evidence in case of emergency.

　　Dear family members, don’t be greedy for small profits. Be sure to keep your eyes open before sending express delivery! After all, it’s all money!

　　LED car lights are suitable for various lighting applications in automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signals, daytime running lights, pedal lights, instrument lights, license plate lights, door lights, interior lights, width lights, navigation, entertainment systems, backlights and indicator lights. Compared with traditional light sources, LED light sources have large differences in physical size, luminous flux, spectrum, and spatial distribution of light intensity. Therefore, LED detection cannot replicate the standards and methods of traditional light source detection.

　　What Are the Most Common Detection Technologies for LED Headlights?

　　Detection of optical parameters of LED lamps

　　1. Luminous intensity detection

　　Light intensity is the strength of light, which is the amount of radiated light within a certain angle range. Since LED light is relatively concentrated, the inverse square law does not apply at close distances. Therefore, the CIE127 standard stipulates that the conditions for measuring light intensity are A (far-field conditions) and B (near-field conditions) for measuring the average normal light intensity. The detector area for both conditions is 1cm2. Generally, standard condition B is used to measure luminous intensity.

　　2. Luminous flux and light efficiency detection

　　Luminous flux is a physical quantity that measures the total amount of light emitted by a light source. It represents the sum of the light energy emitted by the light source in all directions. There are two main methods for detecting luminous flux:

　　Integral method: Light the standard lamp and the lamp under test in the integrating sphere in turn, and record their readings on the photoelectric converter as Es and ED respectively. The luminous flux of the standard lamp is known as Φs, then the luminous flux of the lamp under test ΦDED〜Φs/Es. The integral method uses the principle of “point light source” and is simple to operate, but it is affected by the color temperature deviation between the standard lamp and the lamp under test, and the measurement error is large.

　　Spectrophotometry: This method calculates the luminous flux by measuring the spectral energy distribution of the light source \( P(\lambda) \). Use a monochromator to measure the spectral energy of the standard lamp in the wavelength range of 380nm to 780nm on an integrating sphere, and then measure the spectral energy of the lamp under test under the same conditions. By integrating these spectral energy values, the luminous flux of the lamp under test can be obtained.

　　Luminous efficiency is a parameter that describes the efficiency of a light source. It is defined as the ratio of the luminous flux emitted by the light source to the electrical power it consumes. For LED light sources, constant current is usually used to measure luminous efficiency to ensure the accuracy and repeatability of the measurement.
