Product Description: 20 high-power 1W LED light source of imports, more than 50,000 hours life, light control within 10% decline, light aluminum and glass shell material. Recommended environment: lights high 5m, residential road.

LED lights cost / power 20W:
■ Housing: 260 yuan / month * 1 = 260 yuan
Aluminum and glass lamp shell material.
■ Thermal Cup: 8 yuan / month * 20 = 160
Cup is mainly used for thermal heat, mold production and electroplating needs.
■ Aluminium: 30 yuan / piece * 1 = 30 yuan
Aluminum is mainly used for fixed thermal cup and heat dissipation.
■ Reflector / Lens: 1 yuan / month * 20 = 20 per
PMMA material of the secondary concentrator optical efficiency of 93%.
■ Light Source: 9 yuan / pcs * 20 = 180
1W high power are white, the United States Xuming chip, single lumen greater than 95 lumens.
■ PCB board: 3 yuan / piece * 20 = 60
Hex Round PCB, for a fixed light source, and is the aluminum plate, which will help heat dissipation.
■ constant current source: 50 yuan / month * 3 = 150
Constant current source independent plug-in by outsourcing the production of electronic components.
■ Wire + packaging materials: 50
E-wire connection light source, power cord connected to the current bubble yellow fabric + foam + carton packaging.
Total cost: 260 +160 +60 +150 +160 +30 +20 +50 = 712 yuan

LED lights offer / Power 20W:
Price of small quantities (10-100 pieces): Power Conference / Interview
In the bulk price (100-500 only): Power Conference / Interview
Bulk prices (500 or more only): Power Conference / Interview

Our production of LED lamp products in the industry, has four major advantages:
1. Using single 1W LED lamp composed of light efficiency is very good;
2.'s Patented thermal management technology to solve the technical difficulties of the largest LED lights;
3. Using a unique constant current source control technology, effective control of light source life;
4, the secondary light distribution of patented technologies to achieve the best light.
Specifically:
1. The United States imports a single chip package semi 1W high power LED as light source, color temperature 2700k-10000k, color white, warm white, sun yellow three. White Flux 95Lm / W.
2. Light metal structure with unipolar, the base can be directly heat, light assembly in the PCB board with aluminum sandwich, and then paste in the thermal conductivity of aluminum silica glass, the large area of ​​thermal material is aluminum fixed aluminum cup, high thermal conductivity, and heat lamp shell larger space, which will help spread the heat conduction.
3. For wide-voltage (AC85V-265V), to overcome the power generated by the ballast, noise pollution and instability caused by lighting, avoid bringing work to the stimulation of eye fatigue. LED lamp life of 50,000 hours, lighting 11-12 hours a day, according to calculations, LED lights do not need to be replaced in the next 12 years.
4. An LED light source with light means the light distribution, which includes the K-factor chip production management, packaging, process control, white balance, and the deployment of optical design, LED Lens, the second with just that by changing the LED Division I light-emitting angles to improve the light utilization factor. Using lenses and reflectors and other accessories to improve the luminous efficiency. The picture shows the light distribution curve of the bat wing, a perfect survey said.
