Aluminum Lamp Housing Manufacturers introduces the standards of LED street lamps as follows:
1. The light conversion rate is 17%, (the solar energy per square meter is 1000W, and the actual utilization efficiency is 170W).
2. The current street lamp lens material on the market is an improved optical material, with a transmittance ≥ 93% and temperature resistance of -38 to +90 degrees.
3. LED street lamp lens, mainly used for the lens of an LED street lamp, the spot is rectangular, the material is PMMA optical material, the transmittance is ≥93%, the temperature resistance is -38-+90 degrees, and the anti-UV yellowing rate is 30,000 hours without Changes, etc.
4. The average illuminance of road surface illuminance uniformity is 0.48. The spot ratio is 1:2.
5. Comply with road illuminance. (The actual 1/2 center spot reaches 25LUX, the 1/4 center light intensity reaches 15LUX, the lowest light intensity at 16 meters away is 4LUX, and the overlapping light intensity is about 6LUX).
6. It has very good application prospects in new urban lighting. Dimming depth, and the color and other characteristics will not change due to dimming.
7. Adaptation humidity: ≤95%.
8. Quality assurance: 2 years.
Through the above introduction, 50w Street Light Housing Suppliers hopes that you can simply refer to the content of this article in future use.
Led Street Light Housing Wholesaler introduces the method of installing solar street lights:
⒈Fix the components of each part: the solar panel is fixed on the solar panel bracket, the lamp holder is fixed to the arm, and then the bracket and the arm are fixed to the main pole, and the connecting wire is threaded to the control box (battery box).
⒉Before hoisting the solar street light pole, check whether the fasteners of each part are firm, whether the lamp holder is installed correctly, and whether the light source works normally. Then check whether the system is working normally; loosen the solar panel connection line on the controller, and the light source works.
⒊Pay attention to safety precautions when hoisting the main light pole; the screws are well fastened, if the component's sun-facing angle deviates, you need to adjust the sun-facing direction to face the south completely.
⒋Put the battery into the battery box, and connect the connecting wire to the controller according to the technical requirements; first connect the battery, then the load, and then the solar panel; during the wiring operation, be sure to pay attention to the wiring and the terminal marked on the controller. Wrong connection, the positive and negative polarities cannot collide, and cannot be reversed; otherwise, the controller will be damaged.
⒌Check whether the system is working properly; loosen the solar panel connection line on the controller, the solar street light will be on; connect the solar panel connection line, and the light will be off; at the same time, carefully observe the changes of the indicators on the controller; everything is normal before sealing Good control box.

50w Street Light Housing Manufacturers introduces energy-saving techniques for road lighting:
1. Efficient light source, such as induction lamp, LED lamp
The theoretical life of the induction lamp can reach 60,000 to 100,000 hours, with super long life, high luminous efficiency, high power factor, stable luminous flux output, high reliability, high color rendering, low harmonic content, quick start at low temperature, instant restart, Wide color temperature range, no flicker, no glare, etc. The induction lamp is also an environmentally friendly and pollution-free light source, representing the direction of today's green lighting. In today's environment where energy saving and environmental protection are vigorously advocated in the world, induction lamp lighting is conforming to the lighting The development of the trend, the induction lamp will occupy an important position in the future lighting world. At present, the luminous efficiency of LED is only 50lm/W, which is much lower than sodium lamp 120lm/W. Sodium lamp tube can withstand the high temperature of 800 degrees and work normally, while at the same luminous flux, the heat is more serious LED, semiconductor material limit temperature is only 150 degrees, package The resin temperature is lower, the resin ages very seriously at high temperatures, and the LED is affected by the characteristics of the exciting material, and the light half-life is short. These are problems that cannot be solved at present. At present, LED has become the mainstream lighting source, and there is no theoretical support.
2. High-efficiency reflective lamps
The use of new materials and optimizing the angle of reflection can appropriately improve the light efficiency and change the sanding habits of traditional landscape lamp balls. The use of directional coating internal luminescence technology can greatly improve the ground illumination of traditional landscape lamps. Timely cleaning of lamps is also one of the means of energy saving.
3. Control energy-saving "according to time period and scenario"
For urban road lighting, the most effective and concise method is to use multi-period "scene" energy-saving control to save energy. The lighting of cities, highways, and tunnels is different from commercial lighting or household lighting. For occasions where the precision assembly is required in the workshop, the lighting must meet the specified value, otherwise, the energy-saving illumination will be low, the defective products will be more, the unit qualified products will use more energy, the wages, and other expenses will be more cost-sharing, and the gain will not be worth the loss. In these fixed lighting occasions, methods such as replacing the light source of lamps and lanterns are generally used to meet the requirements of illuminance and energy saving, and people can turn off the lights. For urban lighting, it is difficult to meet the needs of road lighting scenarios in the middle of the night and later in the middle of the night by using fixed voltage reduction or changing the light source of the lamp and changing the low power.
