Large angle into a straight tube type LED lamp highlights?

"We LED this is the angle of light tube, can completely replace the traditional fluorescent lamp, and the light is softer, there is no dark zone, but also highlights the advantages of energy saving and environmental protection LED light source. "Shun Shun Lighting Sales Manager Zuo Xiaoniu told reporters.

"Chinese market might be the LED lights, and not the ceiling lamps nor bulb, it refers to the market sales volume is relatively large, at least 1000-2000 million to the market. Hopefully this year is the first LED lights up. The LED lamp power can reach more than 50%, the manufacturers also have more confidence. Industry experts pointed out.

Although there is some controversy in front of the straight pipe LED specification, but still can not stop the rapid increase in its market penetration, straight tube type LED lamp has become one of the highest sales of products. In addition to further enhance the whole lighting effect, achieve better illumination effect, the reporter learned that, in order to completely replace the traditional fluorescent tube effect, with the rapid competition occupy a larger market share, many manufacturers are constantly emitting angle will increase the straight type LED lamp as its research focus. Light lighting, Shanghai Han Wei, sun lighting, firefly group and other companies have been listed or production is developing straight type LED lamp, more luminous angle for a time, seems to be a greater angle of light straight type LED lamp become a new bright spot.

Conventional fluorescent light emitting angle is 360 degrees due to light, LED light source characteristics of directionality light emitting angle, straight type LED lamp generally only about 120 degrees, it will form a dark area on the side and back, to a certain extent will affect the overall appearance of the lighting and environment. Therefore, many enterprises in order to achieve a more uniform and complete substitution effect, the research focused on the expansion of light angle, has said the light angle straight tube type LED lamp can be all the light emitting angle of 360 degrees. But experts said, the so-called light emitting angle, in accordance with the relevant standards and not all the light reached 360 degrees is the whole point of light, but a certain proportion of the light emitting angle more than 320 degrees can be.

According to the reporter, at present large angle light is mainly realized through the following method: (1) to make the chip sinking enlarges the lighting angle, only the Shanghai Han Technology Co. Ltd. through the power supply at the end of the tube tube, save space and make the chip sinking, thereby expanding the light angle. The use of a unique integrated lighting technology to reduce heat dissipation channel, so that the LED chip can sink, LED light-emitting surface distance from the PC pipe wall increases, thus effectively expanding the exit angle of light. (2) materials to achieve greater light angle through the transparent tube, such as glazing lighting through PC tube technology, high transmittance of more than 85% of the diffusion PC material not only achieved more uniform illumination effect, but also makes the light emitting angle increases, the surface of the lamp light angle to 300 degrees. The T8 lamp on the top of the lamp with a full glass material, expand the light angle, coupled with a unique design can reach 360 degrees out of the light angle.

LED light emitting angle is done, but there are concerns in the industry, the full angle of light is necessary? LED is a directional light source, so it did not play its advantages, reducing the light effect. "

"The main have from the application point of view, if the application environment requirements are not so high, make the luminous angle of 120 degrees is enough, if there are special environmental requirements, so do the whole point of view more uniform luminous nature is good. Hua Zhaohong, deputy chief engineer of Wuxi opto Electronics Technology Co., Ltd., told reporters in.

At present, LED products are mainly to take the high-end market, so the quality of light and light environment is very important to occupy the high-end market can also establish a good reputation LED is the direction of enterprises should strive.

Now products and technology are in a hundred schools of thought contend, but also did not stabilize, and ultimately what technology will become the mainstream technology, which products better, I am afraid that the market has the final say. The luminous angle LED lamp is accredited to the market have the final say, but at least it can serve as one of the highlights of the product. Fudan University professor Fang Zhilie frankly.
