From outdoor lighting to indoor lighting, from general to special, LED applications are expanding, and medical lighting is one of them. Compared with general lighting, medical lighting has certain specialities in terms of lighting demand and market access, and it has not yet been widely popularized. Despite this, with the advancement of technology and the growth of demand, LED medical lighting is still optimistic about the industry, and domestic LED medical lighting is also constantly developing.
LED features and advantages in the field of medical lighting
As a special way of lighting, medical lighting has certain special requirements. Compared with traditional medical lighting, LED has the advantages of orientation and low-spectrum damage, which has become an advantage in the field of medical lighting.
It is understood that medical lighting has fixed-point, directional illumination, high-intensity illumination, and pure light color (with excellent color rendering, which enables doctors to clearly distinguish different organs and organizational structures, and preferably to a certain extent can be carried out as needed Color temperature adjustment to highlight certain organs or tissues) and uniform, shadowless illumination, low-spectrum damage, structural seal disinfection, structural ventilation, dimming control, high reliability and other special needs.
Traditional medical lighting has long used halogen lamps as a light source. In recent years, metal halide lamps have been used as light sources. Halogen lamps and metal halide lamps are typical divergent light sources that diverge in all directions, so that high-heat radiation, full-spectrum, and divergent light sources must meet a series of special technologies to meet the above-mentioned special technical requirements for medical lighting (surgical shadowless lamps). . For example, in terms of dimming control, the halogen lamp achieves light intensity control by adjusting the power supply voltage, but the change in light intensity affects its color temperature and color rendering.
Compared with traditional medical lighting products, LED has inherent advantages in achieving fixed-point, directional illumination, high-intensity illumination, dimming control, high color rendering, and low-spectrum damage, which can effectively overcome the shortcomings of conventional medical lighting. For example, LED is a point source, directional illumination source, and only through a reasonable chip and package design, and with a little secondary light distribution, can achieve ideal directional illumination, its optical system is simple, light distribution effect is ideal; LED The emission spectrum is all in the visible light region, and there are no harmful spectral components such as ultraviolet and infrared rays, which can prevent the damage of ultraviolet light on human tissues and the evaporation of body fluids caused by infrared light and tissue burns.
It can be said that replacing the conventional electric light source represented by a halogen lamp with a new LED light source is beneficial to improving the quality of clinical examination and diagnosis and surgical treatment in medical surgical lighting, medical examination illumination and medical auxiliary diagnosis and treatment illumination. To achieve green lighting.
The medical lighting market has a high threshold and a small scale, but the actual market value is large.
As mentioned above, LED lighting products are more likely to meet the requirements of medical lighting than traditional medical lighting products. The characteristics of LED itself and the particularity of the medical lighting market make medical lighting one of the best entry points for LEDs.
The general medical lighting field mainly includes inspection lighting, surgical lighting, and therapeutic lighting. Among them, surgical lighting represented by surgical shadowless lamps and oral lighting is the typical representative with the highest technical difficulty, the most demanding safety requirements, the highest price and the most complicated design. Some insiders also pointed out that in the medical field, in addition to surgical shadowless lamps, local inspection lighting fixtures, such as dental lamps, endoscope lamps; surgical lighting for regional lighting, surgical preparation lighting; for the treatment of special diseases Light therapy equipment, such as photodynamic therapy equipment, neonatal jaundice treatment instrument, ultraviolet disinfection lamp, etc., are suitable for promoting LED medical lighting.
From the market point of view, the unique technical requirements and characteristics make medical lighting represented by surgical shadowless lamps become extremely special products in lighting products. It must pass the strict clinical trial assessment and obtain medical devices in accordance with the regulations of medical device management. Product license. Therefore, it is a high-tech, high-risk, high-entry special lighting product that can avoid the vicious competition faced by conventional lighting products.
In addition, although medical lighting has a high barrier to entry and a difficult technology, it is only a “small†market segment of medical devices. Most large medical device companies only operate medical lighting products incidentally, and few professional manufacturers make it Medical lighting products are expensive in the market, forming a high price in the field of lighting. The severe price problems faced by semiconductor lighting products in any other general lighting field are relatively less acute in medical lighting.
“Because of the high barriers to entry of medical lighting and the small market size, but the market is expensive, the actual market value of the market is large. The medical lighting field can be said to be one of the best entry points for semiconductor lighting, and it can be used to its strengths and easy to be The field of market acceptance and promotion is also a specialized segmentation market for semiconductor lighting that is easy to see, create a professional brand and go global." Professor Chen Weimin, director of Chongqing LED Lighting Industry and R&D Alliance said.

In short, Dashcoin Dash is a variant of the Bitcoin cryptocurrency that runs on the same blockchain network. Dashi, which combines the words "digital" and "cash," has become one of the most widely watched counterfeit coins in recent months. Originally released as "XCoin", it was later changed to "Darkcoin" and later Dash.
Arguably the biggest benefit of Dashi is that its transactions can be sent completely anonymously, just like legal cash payments. This is achieved by using a hybrid protocol that operates a dedicated network of servers called Masternodes. While Bitcoin operates only a single-layer network of miners, Dashcoin uses these master nodes as additional layers to its network, eliminating the need for a trusted third party to authorise a transaction that could compromise the anonymity of any payment.
Another major difference between Dashcoin and Bitcoin is that the former distributes mining rewards between its mining community, participants holding a specified amount of Dash, and the Dash community's long-term development fund.
