Increase knowledge! Several key parameters that must be paid attention to when selecting LED chips

As costs continue to decline and energy efficiency continues to increase, LED mass adoption is coming, and LED lighting has become the hottest topic in the industry. Because the design involves many technologies such as optics, thermals, and microelectronics, LED designers are usually More attention is paid to the design factors of appearance, heat dissipation, and drive circuit, while neglecting the selection problem. As costs continue to decline and energy efficiency continues to increase, LED mass adoption is coming, and LED lighting has become the hottest topic in the industry. Because the design involves many technologies such as optics, thermals, and microelectronics, LED designers are usually More attention is paid to the design factors of appearance, heat dissipation, and drive circuit, while neglecting the selection problem. At the 2011 International LED Innovation Forum at the Shanghai Electronics Show in Munich, Zhou Xuejun, Marketing Director of Philips Lumileds Asia, delivered a keynote speech entitled "Support for LED Technology Development in Lighting Applications". In this speech, Zhou Xuejun combined with Philips Lumileds to share the LED The view of the key parameters of the chip is believed to be very helpful for designers. Zhou Xuejun revealed that Philips Lumileds has already approved more than 1 billion chips, and accumulated 15,000 hours of measured data, and another 700 million hours of test data accumulation, which is very valuable for LED lighting designers. experience. As LED energy efficiency continues to increase and costs continue to fall, LED chips have begun to price wars. At this time, in addition to considering cost factors, we must consider some other key parameters, such as reliability indicators. Zhou Xuejun pointed out. He believes that the three major indicators that constitute LED reliability should be: Lumen maintenance rate - no lumen maintenance rate, will cause the same batch of LED lamps to vary in brightness, so engineers should learn to look at this indicator curve. For color stability, he suggested that information can be obtained by consulting the manufacturer's LM-80 report. To examine the reliability of the supplier's supply chain - if it is not delivered in time, it will cause your order to fly away! In addition, he also pointed out that to examine the light quality of LEDs, the three elements of this light quality are Consistency, indifference, and color rendering are critical to stable and reliable LED luminaires. In addition, he revealed that there is a QR code on the back of Philips Lumileds' latest generation LUXEON3LED products. Check the QR code to get a lot of information about the chip, such as the date of manufacture, MOVCD information, etc., which also facilitates the maintenance of LED lamps. .

Electric wire rope hoist

Maximum Load:1000-100,1000kg

This novel VT type Electric Wire Rope Hoist is made with 13 patented technologies.

As contrasted with conventional designs, the VT type electric wire rope hoist is a revolutionary new generation product. It houses many brilliant brilliant attributes, such as a superb performance, short headroom, accurate positioning, great operating comfort, and maximum security and reliability, all encompassed in a compact design. It is a multi-functioning machine that has revolutionized the way the wire rope hoist is designed and manufactured.

With a hoisting capacity ranging from 800kg to 250,000kg,the lift can take the load up to a maximum height of 103.6m.Plenty of models, Configurations and specifications exist for the hoist, from which customers are sure to find the perfect match.

Advantages

Short headroom allows large vertical operating space for the wire rope hoist. Size-C hoist design leaves more vertical space for lifting. Such attribute can be hardly found in any of its contemporaries. The hoisting hook can reach much closer to the side walls. Minimum side clearance effectively enlarges the work area.

Dynadrive is designed for stable running and fast positioning. It can minimize the load sway and improve operating safety and comfort. Each component of our electric wire rope hoist is rigorously inspected and tested by our qualified engineers to ensure the safety and working efficiency the final product.

A high load factor 60% can be achieved of the motor, whose cooling performance is 30% higher than other similar products. High performance safety brake has a use life exceeding 1 million cycles. The brake can adjust itself according to the degree of wear. This design requires limited maintenance.

Large-diameter cable reel is designed for extended use life and small fleet angle. During lifting, the rope only deviates a little to the side of the drum, which ensures vertical lifting, accurate positioning, and maximum operating convenience.

Given customer needs for performance and ease of operation. ergonomic features are added to the electrical wire rope hoist to increase operating safety and comfort. Double-layer protective polypropylene coating of the pendant control station enables an IP65 rating.

Plenty of options exist, in order to accommodate various customer needs.
