The following part of this paper summarizes the application scenarios, advantages and disadvantages of 7020 lamp beads to help readers better understand and apply 7020 lamp beads.
Basic concepts and characteristics of 7020 lamp beads
7020 lamp bead is a common LED lamp bead, which is named 7020 because its size is 7.0 mm × 2.0 mm. It is a kind of LED lamp bead with high brightness and high color temperature, which is suitable for indoor lighting and backlight. Compared with traditional incandescent lamps, 7020 marbles are more energy-saving and have a longer life, so they are widely concerned and used.
The characteristics of 7020 lamp beads mainly include the following aspects:
1. High brightness: 7020 lamp bead adopts high-quality chip and packaging technology, which has the characteristics of high brightness, high color temperature and high purity, and can meet the lighting requirements of different occasions.
2. Energy saving and environmental protection: 7020 lamp beads are much more energy efficient than traditional incandescent lamps, which can reduce energy consumption and carbon dioxide emissions, and have remarkable energy saving and environmental protection effects.
3. Long service life: 7020 lamp beads are made of mercury-free, lead-free and other environmental protection materials, which have the characteristics of long service life and low loss, and can greatly reduce the later maintenance cost.
4. Easy maintenance: 7020 lamp bead adopts modular design, which can easily replace a single lamp bead and is convenient for maintenance.
Parameterization standard of 7020 lamp bead
Voltage and current
The voltage and current of 7020 lamp bead are important parameters affecting the brightness and power of its lamp bead. Generally, the voltage of 7020 lamp bead is 2.8 V ~ 3.4 V, and the current is 60mA ~ 150mA. In specific applications, appropriate voltage and current should be selected according to the actual situation.
It should be noted that the voltage and current of 7020 lamp beads will be affected by ambient temperature. Usually, the higher the ambient temperature, the higher the voltage and current, and the higher the power, so the influence of ambient temperature should be fully considered in design and application.
Brightness and color temperature
The brightness and color temperature of 7020 marbles are important parameters affecting lighting effect. Generally speaking, the brightness of 7020 lamp beads is 20lm ~ 25lm, and the color temperature is 5000K ~ 7000K. In specific applications, the appropriate brightness and color temperature should be selected according to the actual needs .
It should be noted that the brightness and color temperature of 7020 lamp beads are affected by current and ambient temperature. Generally speaking, the greater the current, the higher the brightness and the bluer the color temperature; The higher the ambient temperature, the lower the brightness and the redder the color temperature. Therefore, the influence of current and ambient temperature on brightness and color temperature must be considered in application.
Angle of luminescence
The luminous angle of 7020 beads is an important parameter affecting the illumination range and effect of beads. Generally speaking, the luminous angle of 7020 beads is about 120 degrees, which is suitable for a wide range of lighting needs. In specific applications, it is necessary to choose the appropriate luminous angle according to the actual needs.
It should be noted that the luminous angle of 7020 marbles will also be affected by the ambient temperature. Generally speaking, the higher the ambient temperature, the smaller the luminous angle, so it is necessary to fully consider the design and application of ambient temperature.
Drive mode and control mode
The driving mode and control mode of 7020 lamp bead are important parameters affecting its use effect and application scene. Generally speaking, the driving modes of 7020 lamp beads include constant pressure driving and constant current driving; Control includes PWM control and analog control. In specific application, the appropriate driving mode and control mode should be selected according to the actual requirements.
It should be noted that different driving modes and control modes will affect the brightness, stability, life and other performances of 7020 lamps. Therefore, it is necessary to fully consider the advantages and disadvantages of different driving modes and control modes, and select and apply them .
Application scenarios, advantages and disadvantages of 7020 lamp beads
7020 lamp bead has the advantages of high brightness, high energy efficiency, long service life and convenient maintenance, and is suitable for indoor lighting, backlight and other fields. Specific application scenarios are as follows:
1. Home lighting: 7020 lamps can be used in chandeliers, desk lamps, wall lamps and other home lighting places, with the advantages of energy saving, environmental protection and high brightness.
2. Commercial lighting: 7020 lamp beads can be used in commercial lighting places such as shopping malls, hotels and exhibition halls, with the advantages of high brightness, long service life and convenient maintenance.
3. Backlight: 7020 lamp beads can be used in various backlight occasions such as TV, computer and hand-held, with the advantages of uniformity, high brightness and power saving.
However, 7020 lamp beads also have some shortcomings, such as high cost, large calorific value and high requirements for ambient temperature. Therefore, in the concrete application, we should fully consider its advantages and disadvantages, and choose the appropriate application scenario and design scheme .
The above is the detailed introduction of "7020 Lamp Several V 7020 Lamp Parameter Standard". What do you think? For details, please see the relevant suggestions below. The following is a summary of this article.
7020 lamp bead is a common LED lamp bead, which has the advantages of high brightness, high energy efficiency, long service life and easy maintenance.
