The brightness of LED lamp includes: brightness L: luminous flux of the luminous body in a specific direction per solid angle per unit area.
Luminous fluxφ: The sum of the amount of light emitted by the emitter per second. Unit: lumen (Lm) denotes how much the illuminator glows. Note: the larger the lumen, the more the luminous flux, the higher the brightness of the lamp.
LEDs with the same wavelength have the same color. It is difficult for manufacturers without LED spectrometer to produce pure color products.
3. Color temperature
The color temperature is a unit that identifies the color of the light, which is the K. Yellow light which is "below 3300k", white light is "above 5300k" and a middle color is "3300k-5300k". Customers can choose the light source of suitable color temperature according to personal preference, application environment and lighting effect and atmosphere.
4. Leakage current
The LED is a one-way conductor, and if there's a reverse current, it's called a leak. The LED with a large leakage current has a short life span.
5. Anti-static ability
LED with strong anti-static ability, long life has high price. LEDs, usually larger than 700V, can be used for LED lighting.
The key to different qualities is life, which is determined by light decay. Small light decay has a long life.
Each kind of product will have a different design. The different design is applicable to different uses. The reliability design of LED lighting includes: electrical safety, fire safety, applicable environment safety, mechanical safety, health safety, safety and other factors.
8. Energy identification
Energy label is to provide consumers with information about energy consumption and efficiency, which is convenient for consumers to purchase efficient products.
Price reflects the combination of cost, quality and brand value. Ultra-low cost LED products certainly cannot guarantee safety, but ultra-high cost LED may also have virtual high components.
The more functions the product has, the higher the natural cost, but many of the functions are just eye-catching behavior of merchants, which is basically not used in practical applications. So whether the guest lies lamp of ultra modern or romantic living room lamp, the Sunlight Illumination sets the basic lighting as the premise, advocating intelligent simple life.
Different occasions have different lighting standards, and the blindly pursuit of high brightness is a waste, but also may cause harm to people. So, you should confirm the illumine demand first to choose the lamp that accords with demand.
