The difference between array infrared light and high power LED infrared light

The UVLED line light source controller has a user-friendly design, simple operation, and can be configured with multiple irradiation heads to be controlled separately or at the same time, which is convenient for different stations to be used at the same time. UVLED line light source curing device is a kind of UVLED curing light source, UVLED line light source is only light mode, it is through the specially designed optical lens group output a narrow ultraviolet light band, to meet the touch screen edge banding, printing, PCB board coating protection (UV glue curing bonding) and other fields of production needs UVLED line light source curing device 1: cold light source, no heat radiation, especially suitable for liquid crystal edge banding, film printing, medical equipment requires a small heating area for occasions.

2: Instantaneous illumination, 100% power UV output, irradiation intensity up to 7500MW: small form factor - allows the equipment to be easily integrated into fully automated production lines and equipment. 4…

LED Array Infrared Luminescence Technology Features:

High brightness - the output of a single LED array is about 1W 30W, and the brightness is about hundreds of times that of the output of a conventional single LED 5 15MW, so the shooting distance of the product is long;

The electro-optical conversion efficiency is high, the electro-optical conversion efficiency of ordinary infrared LED is only about 10%, while the electro-optical conversion efficiency of LED array (light-emitting diode array) is increased to about 25%;

Small size - LED array (light-emitting diode array) technology highly integrates the light-emitting unit, which is much smaller than ordinary LED infrared lamp products under the same brightness index;

Long life--The life of the LED array is 50,000H (effective life is 10,000H), which is 9 times higher than the ordinary LED life (effective life is 1,200H);

Uniform light - the half-power angle of the LED array luminaire is 10° 120° (variable angle), which can produce (180° shape) of the light-emitting surface, which solves the "flashlight effect" that the ordinary LED indoor space cannot be evenly illuminated and the night vision picture is too bright in the middle and too dark on both sides.

The infrared light angle range is large, and the LED array (light-emitting diode array) luminaire can produce a half-power angle of 10°-180° with lenses at different angles, without the "flashlight effect" of ordinary LED infrared lamps.

1. LED infrared dot matrix light and LED infrared array light are the same product. It's just two different names. From the perspective of a single lamp bead, it will be more appropriate to call it a dot matrix lamp, and it will be more appropriate to call it an array lamp from the lamp board.

2. LED dot matrix lamp array lamp bracket is an imitation lumen type bracket, the chip size is generally 28mil for wafers, 42mil for Guanghong Jingyuan Guanglei San'an, and the current is 700mA - 1200mA (depending on the size and process of each chip brand), and the power is about 2W. Angle. The radiant flux is about 500MW SR.

It is mainly used in surveillance cameras.

3. Focus on why the current and performance of chips of various brand sizes will vary greatly with different processes. There are three aspects that determine the current used in lamp beads: one is the chip brand, the second is the chip size, and the third is the production process.

For example, the wafer 42mil can use 1000mA, while the 28mil can only use 600mA; Guanghong 42mil can only be produced with 800mA current with ordinary process, but if it is produced by eutectic welding process, it can be used to 1000-1200mA. 、、

Array infrared camera refers to the infrared camera installed with the most advanced and latest monitoring infrared lamp, that is, the array infrared lamp.

The core of the array infrared lamp is LED array, it is a strategic LED, its first round light-emitting part is smaller than the nail cover, but in such a small range of light it emits is very large, the product optical path structure uses aspherical optical glass lens, the projection spot is very uniform, which greatly improves the clarity of the monitoring night vision picture and reaches a new stage of recognizable appearance.

Its main advantages are as follows:

1. High brightness - the output of a single LED array is about 1W 30W, and the brightness is about hundreds of times that of the output of a conventional single LED 5 15MW, so the shooting distance of the product is long;

2. The electro-optical conversion efficiency is high, the electro-optical conversion efficiency of ordinary infrared LED is only about 10%, while the electro-optical conversion efficiency of LED array (light-emitting diode array) is increased to about 25%;

3. Small size - LED array (light-emitting diode array) technology highly integrates the light-emitting unit, which is much smaller than ordinary LED infrared lamp products under the same brightness index; Long life--The life of the LED array is 50,000H (effective life is 10,000H), which is 9 times higher than the ordinary LED life (effective life is 1,200H);

4. Uniform light - the half-power angle of the LED array luminaire is 10 ° 120 ° (variable angle), which can produce (180 ° shape) of the light-emitting surface, which solves the "flashlight effect" that the ordinary LED indoor space cannot be evenly illuminated and the night vision picture is too bright in the middle and too dark on both sides.

5. The infrared light angle range is large, and the LED array (light-emitting diode array) luminaire can produce a half-power angle of 10°-180° with lenses of different angles, without the "flashlight effect" of ordinary LED infrared lamps.

1. The first is to select materials.

The main material of LED dot matrix light is chip, at present, most of the chips from Taiwan are used, such as Guanghong Liansheng Jingyuan, Guanglei Dingyuan, etc., all have the production of 42 or 45mil chips, which are used to make infrared dot matrix lights above 2W. The quality of the chip mainly depends on the brightness and temperature resistance. At present, it is more used by Jingyuan and Guanghong, and Liansheng and Guanglei are also used, especially as a rising star of Liansheng, the size is 45mil, which is larger than others, and has certain advantages in brightness and temperature resistance.

2. The second is the process, most of the domestic packaging factories are using silver glue to solidify the process, the best thermal conductivity of silver glue is only 25, the heat dissipation is not good, and it is easy to light decay. Taiwan factory and a few packaging companies in mainland China (Haoyu Hongguang, Cyber Youxun) have realized eutectic process packaging, and the eutectic process is to use alloy solder paste to bond, and the thermal conductivity of alloy solder paste is more than 75. Excellent heat dissipation results in very low light decay.

3. Quality management, the quality management of each enterprise is not the same, and the quality will also be different. Needless to say, the details are the most important.

4. There are two structures of dot matrix lights, one is imitation lumen dot matrix lights, and the other is SMD dot matrix lights, which will become a trend due to the excellent heat dissipation effect of the bracket.
