Luminhome Lighting, LED Lighting manufacture base in China have won lots of appraising from our clients in the past 10 years. We still try our best to provide the better and better LED products & service. Luminhome Lighting always your best choice!
Luminhome lighting provide one-stop services in lighting design and manufacture of LED luminaries.It is an ambitious company commits itself to becoming a worldwide lighting supplier in high-power LED Industrial lighting, Commercial lighting and Family lighting industry.Since its establishment in July, 2003 in Guangzhou by Mr. Simon and Mr. Rondo,Luminhome Lighting has been rapidly developing its business all over the world.
Over 100 of 400 employees constitute the designer team, each of them graduated from well-known universities in China and overseas in the areas of optics, thermodynamics, industrial design, electrical engineering, information engineering, arts, etc. Excellent technical team bring Luminhome lighting gain over 400 domestic patents. on the lighting products.On average, the company applies for over one patent per week, and that speed is increasing. Base on the powerful technical strength, Luminhome lighting offer a secure backing for clients project quality.
Luminhome Lighting also have strong producing capacity, The production department currently can make 30,000 modules and 6,000 luminaires per week. The capacity of producing can provide more enough high quality lighting products for most of the big project in short time.
About the quality control, from the production materials, production of core components, down to the assembly lines, all the way to quality inspection, packaging, storage, and logistics, each process is methodically done in the pursuit of perfection.
The luminous efficiency of LED street lamp
and high pressure sodium lamp is similar. Why can LED street lamp
replace the high power sodium lamp with lower power? How is it converted? The following is a personal view, it is inevitable that there are imperfections, please ask me to correct.
High pressure sodium lamp belongs to point light source, which is 360 degree light emitting. In fact, the light applied to the direction of the radiation is very small, only about 30%. Therefore, the high pressure sodium lamp must reflect the light in the non irradiation direction through the reflector in the lamp, so as to achieve the purpose of higher light utilization. Due to the lamp design and cost problem, the efficiency of sodium lamp is only 40-45%.
The LED street lamp
/ tunnel lamp belongs to the area light source, the luminous surface is a single direction, the light source utilization rate is high, and the lamp efficiency is above 80%.
Here we take 100W LED street lights and 250W high pressure sodium lamp as an example to illustrate this problem.
1. Initial luminous flux of 100w LED street lamp
11000lm. Because the lens loss is 10%, the power loss is 10%, the luminous flux of the lamp is actually 8910lm, and the total power consumption of the lamp is 110W. So the light effect of this LED street lamp
2. The initial luminous flux of 250W high pressure sodium lamp is 25000lm, the light source utilization loss is about 30%, the power loss is about 20%, and the luminous flux is 12500lm, the total power consumption of the lamp is about 300W. So the light effect of this high pressure sodium lamp is 41.67lm/W.
Through the above analysis and comparison of the final luminous efficiency value, we can find that the luminous efficiency of 100w LED street lamp
is almost 2 times higher than that of 250W high-pressure sodium light. This is why 100W LED street lamps
can be used instead of 250W HPS lamps.
