LED lamp has environmental protection, long life, small volume, high directivity, solid form is not easy to damage ... Etc., have gradually replaced the traditional tungsten filament lamp ( incandescent), CCFL fluorescent lamp, but in response to the different application requirements
LED component emitting characteristics, efficiency is the key to the base material and the wafer growth technology differences.
Strengthen the packaging technology to improve the light efficiency and light type
Observation of the common high power LED bulbs technology, can be divided into the single chip package, integrated multi-chip package and chip encapsulation 3 kinds of techniques, and through the packaging technology optimization, can improve the LED chip light emitting efficiency, heat dissipation effect and the reliability of the product.

LED lighting lamps and lanterns of efficacy
Conventional LED street light of the chip, not stem weakness, developed a crystal coated chip mounting method. The surface of the two electrode over the bottom and the direct use of silver soldered to the metal heat conducting substrate. So heat transfer by conduction silver adhesive than previous solid crystal directly.
Recently, South Korea, Taiwan large power LED chip also has to add a layer of metal coating on a sapphire substrate method, it can also be used to replace the silver paste silver paste to the solid crystal. Silver paste after curing, thermal conductivity near sterling silver, silver plastic thermal rate to be high.
Rare earth fluorescent powder is continuously improved, so that the overall lighting industrial benefit - metal halide lamp, high pressure sodium lamp, fluorescent tube energy-saving lamp and the new large power LED spotlight
LED chip if not directly to COB solid crystal on the circuit substrate, will find a fast heat conduction material as with the radiating fins into an intermediate medium. Copper is a metal heat conducting only slightly inferior to the silver material, low price, so the copper is the most common large power LED tube light chip heat transfer material.

Helios Bright Crystal Lighting Co.,ltd is a leading specialist in the field of Custom Architectural Lighting. We have gained decades of experience through intensive development as well as partnership with leading architects and designers to participate in various numbers of significant projects.
We are specialized in manufacturering all kinds of warning light. Our products include Crystal light chandelier,led strip,table light,floor light etc. Most of our products are ISO9001, CE, UL, CCC and SASO certified, fully complying with the industrial standards to better satisfy customers' changing needs.
Having built effective information systems, we are able to provide appropriate and prompt solutions for production, purchasing and warehousing implementations. Moreover, the improvement of quality control system and enhancement of organizational structure have brought us more opportunities and competitive advantages in both domestic and foreign markets. Consequently, our products are selling well in the North American, European and Oceanian markets.
Providing 'crystal lighting, Excellent Service, Reasonable Prices and Prompt Delivery', we are now looking forward to even greater cooperation with overseas customers based on mutual benefits. Please feel free to contact us or visit our website for more information
No project is too challenging for our craftsmen. Our skilled artisans and engineers have the ability and expertise to interpret and execute virtually any lighting designs. While Helios Bright is renowned for our metalwork, electroplate finishing and faux artistry, our successful projects have included materials such as flat and hand blown glass and crystal, molded, shape or formed custom acrylics and resins, wood, leather, parchment, fabrics and other materials too lengthy to list separately.
Every Helios Bright product is designed and manufactured to the highest standards for both beauty and durability. In 2005, We use imported Swarovski as material,which is the best brand of crystal.
We work with customers all over the world to develop products to meet most markets. Designers are welcome to visit and review their drawings or our vast library of completed projects. Please feel free to contact us for additional information.
