What are the advantages of the 2835 SMD LED Chip？
The 2835 conducts the heat of the chip directly to the aluminum substrate by punching holes in the lamp bead bracket and installing a thermal conductive sheet. In order to distinguish it from the heat dissipation method of 3528, its heat dissipation method is also called "thermoelectric separation". This means that heat and current are not conducted through the same wire. The advantage of the 0.2W 2835LED is that it has low heat generation and comes with a heat sink, which is not hotter than a 1 power LED (the heat consumption is large, and a large-area aluminum heat sink must be used, and it is also hot!), no need to focus on heat dissipation.
The LED chip 2835 has 0.12W 14-16LM (chip size is 10*23mil) and 0.2W 22-24LM (chip size is 10*30mil), both of which are suitable for daylight .
Next, GMKJ LED will analyze the advantages and disadvantages of LED SMD lamp beads 2835 for everyone:
(1) LED SMD lamp beads 2835 use a vertical packaging structure: the chip directly connects to the heat sink, and the area of the heat sink is about twice that of 3014, which further improves the heat dissipation performance of the bead body and can withstand greater current ( 40-60mA), the brightness is also higher, and the excellent heat dissipation performance design also guarantees the brightness and life of the LED chip.
(2) Ultra-thin structure: 2835 thickness is also 0.8mm, which can solve the spot problem of 3528; super large light-emitting surface (square light-emitting surface): can increase the light output rate: up to 90%
3) Cost: Take 20W as an example:
1. If you choose to use the 2835 with 0.12W14-16LM, then the 20W fluorescent lamp needs 144 beads, the cost of the light source is 144 0.17 yuan/grain = 2448 yuan, the brightness of the whole lamp is: 144*15LM (single The middle value of the brightness of the lamp beads) * 0.9 (power factor of the power supply) * 0.9 (light output = 1749LM (the brightness of the whole lamp is about 1749M).
2. If you choose to use the 2835 with 0.2W22-24LM, the 20W fluorescent lamp needs 100 lamp beads, and the cost of the light source is: 100 lamps. 19 yuan / lamp = 19 yuan, the brightness of the whole lamp is: 100 x 22LM (The median value of the brightness of a single lamp bead) *0.9 (Power factor) ∞ 0.9
(Light output rate)=1782LM (the brightness of the whole lamp is about 1782LM)
