What is the difference between cold light effect and thermal light effect of 3030 led chip?
3030 smd led is a semiconductor light-emitting device, semiconductor is a heat-sensitive device, which means that it is very sensitive to temperature. In other words, temperature will directly affect its performance and parameters. As an electrical-optical conversion device, its most important indicator is how many watts of electrical power is input and how much luminous flux (lumens) is output. We call it luminous efficiency (luminous efficiency). This indicator represents the most important quality indicator of LED lamp beads. . The user chooses the LED lamp bead with the smallest wattage according to the luminous flux (lumens) he needs.
However, although the LED lamp bead device itself has a light effect, it does not mean that the user can directly enjoy the light effect, because assembling the LED lamp bead device into a lamp will lose a part of the light effect. We do not consider the light transmittance of the photomask (assumed to be 100%, in fact it is usually around 90%), but mainly consider the light effect of the LED lamp bead light source itself. This kind of light effect is also divided into cold light effect and thermal light effect. Probably most people will not pay attention to the difference between these two light effects, so here we will first discuss the issue of cold light effect and thermal light effect.
Simply put, the cold light effect is the light effect measured when the GMKJ LED 3030 smd led light source is at room temperature (25°C), and the thermal light effect is the light effect measured after the LED lamp bead light source is thermally stable. Specifically, we usually use an integrating sphere to measure the luminous efficiency of the LED lamp bead light source, then the luminous effect measured immediately after the power is turned on is the cold luminous effect (assuming that the room temperature at that time is 25 degrees), this "immediately" is about Within 5 seconds. The thermal light effect is to wait at least half an hour to 3 quarters later to reach thermal equilibrium (or thermal stability). Now we usually say that the light effects are cold light effects, or that most of the light efficiency indicators we indicate on the outer casing or packaging are cold light effects.
How many watts of 2835 smd led?
The 2835 led white light market is more common with a single 0.2W, this is the one that replaces the 3014 smd led and the 4014 led.
In addition, 2835 smd led is used in bulb lights, most of which use a single 0.5W power smd led.
Therefore, many bulbs use a single 0.5W power, and the 5730 smd led has the same power.
Of course, there are some high-end ones that are used in teaching lighting products, or ceiling lamps, and will choose to use a single 2835 lamp bead 1W.
How many watts of 2835 smd led?
2835 smd led mainly has 3 series of white light of 0.2W, 0.5W and 1W and 2 series of power color light of 0.2W, 0.5W.
