Nowadays, the LED lamp market is becoming more and more mature, and the market that needs it is also expanding. Some LED manufacturers have mixed the ball with the secondary products. Therefore, the Ministry of Industry and Information Technology announced the collection of "LED bulb performance requirements." As far as the experience of the new light source LED lamp manufacturer and the standards of its own production are concerned, it is felt that the performance of the
LED bulb should meet the following requirements for discussion.
1. Safety: The safety of LED bulbs should be considered in the first place. At present, LED bulbs are commonly used in aluminum metal casings, which is the most accessible part of the user, but the metal is easy. Conductive, the use of aluminum shell makes the LED bulb lamp have the safety hazard of electric shock. Therefore, it is better to have certain requirements on the insulation of the heat sink of the LED lamp, such as ceramic, plastic and other insulating materials to ensure foolproof.
2, life requirements: One of the characteristics of LED lights is a long service life, but some LED manufacturers are limited to price competition, not using the standard materials,
Or the professionalism is not enough, the heat dissipation design and the drive circuit design are not in place. The life of the LED bulbs that do this does not meet the standard. This kind of hidden bad will damage the consumer rights. Therefore, it should be There is a reasonable limit to the service life of LED lamps, such as L70>25000 hours.
3, optical performance requirements: some LED bulb manufacturers with low color to improve the luminous flux of LED lights, so that the performance level of color is low, even lower than energy-saving lamps, which is unreasonable, therefore, LED manufacturers recommend Light color and color rendering are regulated. For example, LED bulbs in home and commercial space should be defined at Ra>80. In addition, the range of various shades should be defined to define the range of white light and neutral light of LED lights. .
The above performance specifications can be used not only for LED bulbs, but also for other LED lamps, such as LED ceiling lamps, LED downlight performance specifications, etc.
In this hope, each LED lamp factory can produce more and better LED lamps to ensure the interests of consumers.
Silicon TVS / TSS:
Diode TVS (Transient Voltage Suppressor), also known as Transient suppression diodes, is widely used a new type of high efficient circuit protection device, it has a fast response time (the nanosecond) and high surge absorbing ability.When it ends of stand moments of high energy shock, TVS can bring the two ends at high rate from high impedance to a low impedance between impedance values, to absorb a large current moment, put it at both ends of the voltage restraint on a predetermined value, thus protecting the back of the circuit components are not affected by the impact of the transient high pressure spikes.
