Product characteristics
1. Light source module:
Using high brightness LED light source and high efficiency constant current drive power, it saves 60% of the power than gas discharge lamp; all the LED components are sealed, waterproof and dustproof, without internal cleaning and maintenance; the circuit board has low thermal resistance, and the specially designed module circuit, each unit failure will not affect the normal work of other components.
2. Power module:
High efficiency constant current drive power supply with intelligent power regulator; with the function of light flux compensation, reducing light attenuation, ensuring the light efficiency of LED light source; with over-voltage protection, over-current protection and burst current protection functions.
3. Heat dissipation module:
The shell of explosion-proof lamp is formed by high-pressure casting of aluminium alloy, and the heat dissipation performance of the shell is effectively improved by high-voltage electrostatic spraying after shot blasting; the circuit board is close to the aluminium alloy shell, which can instantly convert the point heat source to the surface heat source, and the heat dissipation area is doubled, which is conducive to rapid heat dispersal and improve the heat dissipation efficiency; the shell surface has airflow dispersion groove, which takes heat away by means of air flow. The fin has high density, greatly enhances the thermal area, fully guarantees the heat dissipation requirements of the LED, and has a longer service life.
4. Light Distribution Module: Light Distribution Components specially designed for each type of lamp, giving full play to the performance of the lamp
5. Without ultraviolet radiation, it can provide high-quality lighting and health protection for users who work indoors for a long time.
6. This series of lamps and lanterns belong to maintenance-free products, energy-saving and environmental protection;
7. Rotation angle of wall mounting can be adjusted, cable wiring and suction top mounting can be wired by cable or steel pipe.
Characteristics of LED Light Source
1. High luminous efficiency
The efficiency of incandescent lamp is 7-14 lm/W, fluorescent lamp is 50-80 lm/W, and high pressure sodium lamp is 80-120 lm/W. Most of the power consumption becomes heat loss. The light efficiency of LED can reach 90-120 lm/W, and its light has good monochromaticity, narrow spectrum, selective color temperature and good color rendering.
2. Low power consumption
LED single power 1 ~ 3W, DC drive, single tube drive voltage 3 ~ 3.5V, current 0.35 ~ 1A, fast response, high frequency operation. Under the same lighting effect, the power consumption is one eighth of the incandescent bulb and one half of the fluorescent tube.
3. Long service life
The common light source uses the electronic light field to emit light, which has the disadvantages of burnable filament, thermal deposition, light attenuation and so on. The LED light source is small, light weight, epoxy resin packaging, can withstand high strength mechanical impact and vibration, not easy to break. The theoretical life of the lamp is 100,000 hours, which can greatly reduce the maintenance cost of the lamp and avoid frequent lamp change.
4. Safety and reliability
Cold light source, no thermal radiation, can accurately control the light type and luminous angle, light color is soft, no glare; does not contain mercury, sodium and other substances that may endanger health. The built-in micro-processing system can control the luminous intensity and adjust the luminous mode.
5. Benefiting the Environment
LED is all solid state light emitting body, shock resistant, impact resistant and not easy to break, waste can be recycled, no pollution;
6. Low cost of use
The price of LED light source is slightly higher than that of traditional light source, but the investment of light source can be recovered by saving energy in one year. LED is a maintenance-free light source, which can save maintenance costs in the next few years and greatly reduce the use cost.
