The Chinese market may rise up with LED tube lights, not ceiling lamps or bulbs. It means that the market sales are relatively large, at least 10-20 million. More promising this year is the LED tube light first. LED tube lights can save more than 50%, and manufacturers are more confident. The LED tube lamp is full-angle illumination, which can completely replace the traditional straight tube type fluorescent lamp, and the light is softer, there is no dark area, and it also highlights the advantages of energy saving and environmental protection of the LED light source.
Although straight-tube type LED lamps have some controversy in terms of joint specifications, they still cannot prevent the rapid increase of market penetration rate. Straight-tube type LED lamps have become one of the products with the highest sales volume. In addition to further improving the overall lighting efficiency and achieving better light-emitting effects, in order to achieve the effect of completely replacing the traditional fluorescent tube, competing with it to quickly occupy a larger market share, many manufacturers will continue to increase the luminous light of the straight tube type LED lamp. The angle is the focus of its research and development. LED companies have already produced or are developing straight-tube LED lamps with larger illumination angles. For a time, it seems that a larger angle of illumination has become a new bright spot for straight-tube LED lamps.
The illumination angle of the traditional fluorescent tube is 360 degree. Due to the characteristic of the directivity of the LED light source, the illumination angle of the straight tube type LED lamp is generally only about 120 degrees, which will form a certain dark area on the side and the back, which will affect to some extent. Overall lighting effects and environmental aesthetics. Therefore, in order to achieve a more uniform and completely replaceable effect, many companies have focused their research and development on expanding the angle of illumination. At present, some enterprises have indicated that the angle of illumination of their straight-tube type LED lamps can achieve 360-degree full-angle illumination. . However, some experts said that the so-called full-angle illumination, according to the relevant standards, does not mean that all light reaches 360 degrees, it is called full-angle illumination, but a certain proportion of light has an exit angle of more than 320 degrees.
According to the reporter's understanding, the current large-angle illumination is mainly achieved by the following methods: (1) to make the chip sink as much as possible to expand the illumination angle. A company in Shanghai puts the power supply on one end of the lamp to save the space inside the tube and sink the chip. Increase the angle of light. A lighting company adopts a unique integrated heat dissipation technology to reduce the heat dissipation channel, so that the LED chip can sink, and the distance between the LED light-emitting surface and the PC tube wall is increased, thereby effectively expanding the light exit angle. (2) Achieve greater light exit angle through the full light-transmissive tube material. For example, the glazing illumination through the full PC tube technology, the diffused PC material with a transmittance of more than 85% not only achieves a more uniform light-emitting effect, but also makes the light-emitting angle When it is enlarged, the surface of the lamp has an illumination angle of 300 degrees. X Lighting's T8 tube is made of all-glass material, which expands the angle of light, and the unique design can achieve a 360-degree angle of light.
LED lamps with full-angle illumination have been made, but there are also concerns in the industry. "Is full-angle illumination necessary? LEDs are originally directional light sources, which instead of exerting their advantages and reducing light efficiency.
Mainly from the application point of view, if the application environment is not so high, it is enough to achieve a 120 degree illumination angle. If there are special environmental requirements, then it is better to achieve a more uniform illumination at all angles. .
At present, LED products are mainly used in the high-end engineering market, so it is very important for the expression of light quality and light environment. Occupying high-end market can also establish a good reputation of LED, which is the direction that enterprises should work hard.
Now that products and technologies are in the stage of contending for a hundred schools, they have not stabilized. In the end, what kind of technology will become mainstream technology, and which products are better, I am afraid that the market has the final say. Whether the LED tube lamp with full illumination angle is recognized or not has the market to say, but at least it can be used as a highlight of the product.
