The latest LED light developments
All the major LED suppliers have released additional lighting-class LEDs over the past few months, particularly at the high-power end for light bulb and downlighter replacement.
Cree's latest is the XM-L, sampling in 2,600K to 5,000K colour temperatures, with neutral whites predicted to be capable of 850 lm, and 84 lm/W, at 3.0A.
Incandescent bulbs are 10-15 lm/W, emitting at least as much as a 60W light bulb.
At 350mA, 3,000K (warm white) XM-Ls will deliver up to 113 lm and 117 lm/W, and 4,000K (neutral) up to 134 lm and 138 lm/W.
Double the current and 3,000K LEDs will hit 220 lm and 108 lm/W, and 4,000K will deliver up to 260 lm and 128 lm/W.Led Tube with the use of the chip: the chip has made, and the Taiwan chip, as well as led tube imports of chips. Different chips, prices vary widely. Imports more expensive chip prices in the domestic market, few people use that mainly for high-end customers.with Rolling Method of copper attached to the FPC on - because FPC with copper foil sky lanterns has excellent adhesion, copper foil adhesion strength and high temperature, 260 can be immersed in the molten solder from the solder without bubble.
Cree
For 35W-50W halogen MR16 retrofit bulbs, Cree has developed the 12-die 9x9mm MT-G.
"Cree engaged driver, thermal and optic providers to create an MR16 lamp reference design to further enable customers to address this market," the company said.There are many small packaging plant the absence of color separation machine, so regardless of fluorescent bulbs or color, or is contracted out. This is difficult to guarantee the quality
The reference design, which can be found on the firm's website, makes educational reading even if Cree is not your LED maker of choice.
Binned and tested at 85°C - a trend that is to be applauded as this is a more realistic operating temperature for bulb replacements - the 3,000K version delivers 560 lm at 1.1A, or up to 1,525 lm at 4A.
Filling in its range, the firm has also added the 0.25W 3.5x3.5mm ML-B LED for distributed lighting - panel lights and fluorescent tube replacements, for example.
Luminous flux from the 5,000K (cool white) LEDs is up to 30 lm at 80mA, and up to 24 lm in 3,000K.
Lumileds
Lumileds is going for the retrofit bulbs market with a high-voltage LED that can run from rectified AC and "eliminates the need for a DC electronic driver", said the firm.
The Californian firm is not the first to offer high-voltage LEDs. Seoul Semiconductor beat it by several years with its Acriche range, which uses large numbers of die connected in series.
Called Luxeon H, the Lumileds high-Vf device runs on approximately 50V. At 4.5x3mm, a few can be fitted in a luminair, plus a dropper resistor to set the current to 20mA from 120V or 240V.
"The base of some bulbs is so small that it is impossible to fit both an electronic driver and a heatsink in the space. Luxeon H only requires a bridge rectifier and a resistor, both of which are very small, and the remaining space can be used for thermal management," said Lumileds vice-president of product marketing Frank Harder.
Targets are candelabra bulbs and Edison E10-E17 types.
Two colour temperatures are available: 2,700K and 3,000K, with typical CRIs of 83 and typical flux of 84 and 90 lm respectively.
Another introduction, Luxeon S, is a first among lighting LEDs,sub-package and silicone resin package. Resin package prices cheaper, because the thermal performance dsttマジコン a bit weak, others are the same. Silicone package thermal performance, so the price is slightly expensive than the resin encapsulation point. as colour consistency has been improved to the point where no colour binning is required.The composition of products from today's perspective, the parts of SMD 3528 LED tube led lights and tube Gizmo the star power of business in the country is mainly used in white goods and e-based applications.
"All S emitters are targeted to the black body curve and populate an area within a three-step MacAdam ellipse," claimed the firm.
