"Our LED tube light is full-angle light, can completely replace the traditional straight tube fluorescent lamp, and the light is softer, there is no dark area, but also highlights the advantages of LED light source energy saving and environmental protection." Shangyu lighting sales manager Zuo Xiao Niu told reporters.
"The Chinese market will probably rise up with LED tube light, not ceiling light or bulb light. It means that the market sales volume is relatively large, at least 10 million to 20 million are counted as the market. This year's more promising is the LED tube light. First up. LED tube light can save more than 50%, manufacturers are also more confident.†Industry experts pointed out.
Although there were some controversies regarding the connector specification before the straight-tube type LED lamp, it still could not stop the rapid increase of its market penetration rate. The direct-pipe LED lamp became one of the products with the highest sales volume. In addition to further improving the overall lighting efficiency and achieving better light output, the reporter learned that in order to achieve the full replacement of the effects of traditional fluorescent tubes, and compete with them to quickly occupy a larger market share, many manufacturers will continue to increase the direct control type. LED lighting angle as its focus of research and development. Shanghai Everlight Lighting Co., Ltd., Shangyu Lighting Co., Ltd., and Firefly Group have already produced or are developing LED lamps with larger light-emitting angles. For a time, they appear to be a new angle and become a new type of straight-tube LED lamp. The highlights.
The traditional fluorescent tube has a 360-degree light emitting angle. Due to the directional light-emitting characteristics of the LED light source, the straight-tube LED light has a light emitting angle of only about 120 degrees, which will form a certain dark area on the side and back, which will affect the level to some extent. Overall lighting effects and environmental aesthetics. Therefore, in order to achieve a more uniform and complete replacement effect, many companies will focus their R&D efforts on expanding the lighting angle. At present, some companies have stated that the light emitting angle of their straight-tube type LED lamps can be 360°. . However, some experts said that the so-called full-angle light, according to the relevant standards, not all light reaches 360 degrees before it is called full-angle light, but a certain proportion of the light's exit angle exceeds 320 degrees on it.
According to the reporter's knowledge, the current large-angle light emission is mainly achieved through the following methods: (1) As far as possible, the chip sinks and expands the light-emitting angle. Shanghai Juwei Technology Co., Ltd. saves the space inside the tube and reduces the space under the chip by placing the power supply at one end of the tube. Shen, so as to expand the light angle. The use of a unique integrated cooling technology in the lighting lighting has reduced the cooling channels, which allows the LED chips to sink. The distance between the LED light emitting surface and the wall of the PC tube increases, which effectively expands the light output angle. (2) Achieve larger light-emitting angles through full-transmission tube materials. For example, through the full PC tube technology, the diffused PC material with a light transmittance of 85% or more not only achieves a more uniform light-emitting effect, but also makes the light-emitting angle. Increase, the surface of the lamp reaches 300 degrees. The T8 lamp of Shangyu Lighting is made of all-glass material, which expands the angle of light output, and the unique design can achieve a 360-degree viewing angle.
All-round LED light bulbs have been made, but there are also industry insiders, "does the whole point of light is necessary? LED has always been a directional light source, so instead of playing its advantages, reducing the efficiency of light."
"The main point is that from the point of view of application, if the application environment does not have such a high requirement, it will be sufficient to achieve a luminous angle of 120 degrees. If there are special environmental requirements, then it is natural to achieve a more uniform light emission from all angles. The deputy chief engineer of Wuxi Huazhao Hong Optoelectronics Technology Co., Ltd. Li Jiemin told reporters.
At present, LED products are mainly used in the high-end engineering market. Therefore, it is very important for the expression of light quality and light environment. Occupying the high-end market can also establish a good reputation for LED. It is the direction that companies should strive for.
"Now the products and technologies are in a stage of contending, and they have not yet stabilized. Ultimately, what kind of technology will become the mainstream technology, and which product is better, I am afraid that the market will have the final say. Is LED tube light with full light angle also recognized? The market has the final say, but at least it can be a bright spot for the product,†said Professor Fang Zhilie of Fudan University.
