With the widespread use of LED luminaires, the number of manufacturers of LED luminaires has gradually increased, resulting in confusion of LED products. There are thousands of LED products on the market, and the materials used are different. Conventional LED luminaires are available in aluminum and die-cast aluminum heat sinks. The quality of the material will affect the heat dissipation performance of the luminaire, resulting in the difference in the life and fading of the luminaire. The good products are made of die-cast aluminum, which is more conducive to the heat conduction of the luminaire.
All the chips and driving power of the lamp itself directly affect the life of the lamp (use time), but it is also inseparable from the heat dissipation material. Domestic chips generally have a life expectancy of about 30,000 hours, and the imported chips and the drive life of foreign CE certification and ROSH certification are around 50,000 hours.
For home improvement, most consumers nowadays are not asking for how bright the lights are, nor for buying cheap ones, but for pursuing lighting effects and highlighting the family atmosphere. According to years of experience in sales and home improvement companies, sales technicians told reporters that he felt that the living room, bedroom and bathroom can use LED spotlights with high color rendering index and long life, and the color temperature is 3000K, which makes the lighting layered. The restaurant can use floodlight LED lamps with a color temperature of 4000K-5600K. The operation room can make the lights look brighter.
The life depends on the heat dissipation, the heat depends on the material, and generally the heat is dissipated in aluminum. Now the LED development panel light is more suitable for each room (and its own aesthetic), and the light is softened through the transparent version. And the brand manufacturers have indeed achieved the advantages of energy saving and long life. LED lights are mainly looking at the light, there are many parameters in the professional angle, and households can choose the light source of brands such as Philips.
The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. When they were introduced, D-subs were among the smallest connectors used on computer systems.
A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support, ensures correct orientation, and may screen against electromagnetic interference. The part containing pin contacts is called the male connector or plug, while that containing socket contacts is called the female connector or socket. The socket's shield fits tightly inside the plug's shield. Panel mounted connectors usually have threaded nuts that accept screws on the cable end connector cover that are used for locking the connectors together and offering mechanical strain relief. Occasionally the nuts may be found on a cable end connector if it is expected to connect to another cable end. When screened cables are used, the shields are connected to the overall screens of the cables. This creates an electrically continuous screen covering the whole cable and connector system.
