At present, the sales of LED automotive lighting market maintains a growth rate of about 10 per year, but the proportion of domestic LED automotive lamps is not high. The models with relatively large LED usage are concentrated in the mid-to-high-end auto companies, and these auto companies generally have restrictions on the LED brand, and domestic LED companies are more difficult to enter their supply chain. LED lighting as a green light source, lighting has always been our focus.
LED lamp DC drive, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong directionality; good dimming performance, no visual error when color temperature changes; cold light source Low heat and safe touch; these are not possible with incandescent and fluorescent lamps. It not only provides comfortable lighting space, but also satisfies people's physiological health needs. It is a healthy light source that protects vision and is environmentally friendly.
Since the current single LED has low power and low brightness, it is not suitable for use alone, and assembling LEDs together to design a practical LED lighting fixture has broad application prospects. The luminaire designer can determine the shape of the optical system of the luminaire, the number of LEDs and the power according to the requirements of the illumination object and the luminous flux. It is also possible to design several LED illuminating tubes into a secondary source of point light source, ring light source or surface light source. The luminaire is designed according to the combined secondary light source.
The term LED lamp supplier is popular in China in recent years, and people familiar with the lighting industry are no strangers. Semiconductor light-emitting diodes, referred to as LEDs, have been developed since the 1960s and are gradually becoming market-oriented. For those unfamiliar with the lighting industry, the following describes semiconductor light-emitting diodes:
First, the energy consumption is low, and the light decay is small. The brightness of a 1W LED is equivalent to a 35W halogen spotlight. In the history of the development of lamps, local lighting has always been the absolute leading position of halogen lamps and metal halide lamps. The birth of LEDs will replace them in the future.
Second, the long service life, no need to replace the light source, no maintenance, this is actually the most worrying problem for consumers. Consumers are not professionals, there is no professional inspection equipment when selecting products, no professional maintenance knowledge, and LEDs solve their worries.
Compared with international famous brands, domestic LEDs may have more problems in terms of life and uniformity of sorting. At the same time, the market regulation of auto lamps itself is strict, the threshold is relatively high, and automobiles are used as luxury consumer goods. One-on-one customers, any quality problems will cause complaints, domestic LEDs have no chance to go through this market long-term large-scale experience, it is difficult to reach the automotive LED standard. Automobile lamps are very professional fields. It is necessary to do LED car lamps. Whether it is car lighting companies or LED enterprises, it is very difficult to go it alone. It is necessary for car lighting companies to fully communicate with LED companies, especially in front of LED cars. Development of the light.
Common mold frame: an important tool on the construction site
In the construction site, we often see a variety of tools and equipment, one of the most common is the ordinary mold. As an important construction auxiliary tool, the common die frame has been widely used in the construction industry. This paper will introduce in detail the related issues of the common die frame, including its background, composition, assembly, use and maintenance.
A common mold frame is a formwork used for concrete placement, which is composed of profiles and accessories that can be combined into formwork of different shapes and sizes according to different needs. In the construction site, the ordinary mold frame is mainly used for the pouring of concrete structures such as walls, beams and slabs. Due to its characteristics of reusable, convenient assembly and low cost, ordinary die frames have become important tools in construction sites.
The basic components of a common mold holder include profiles and accessories. Profiles are usually made of steel or wood and are used to form the frame and support structure of the template. Accessories mainly include bolts, nuts, washers, latches, etc., used to connect and fix profiles to ensure the stability and reliability of the template.
The assembly process of the ordinary mold frame is relatively simple, but some details need to be paid attention to. First, it is necessary to determine the shape and size of the required template according to the construction drawings, and then select the appropriate profiles and fittings. In the assembly process, it is necessary to follow a certain sequence and steps,
