With LED projector lamp, what specifications do you need LED?

Answer:

LED light source: almost no heat dissipation design, or simple heat dissipation design, no high voltage circuit. LifeTraditional light sources: usually hundreds to thousands of hours.LED light source: more than 50 thousand hours (if 24 hours of uninterrupted play, still can use five years time! Light utilization traditional light source: only of the light is effectively utilized due to the scattering of light from the light source to 360 degrees.LED light source: light travels only in front, and can be used almost exclusively. Energy consumption traditional light source: more than 150 watts, the average household projector is about 250 watts.LED light source: 10 watts to work, I have made 10 watts products, the projector assembly can clearly display the image in a dark room, estimated to reach the same brightness effect, only the traditional projector light source power 20%-50%. The traditional light source containing harmful light: infrared, ultraviolet and other harmful rays, infrared will cause the temperature of the liquid crystal panel increases, the need for cooling the liquid crystal panel design, ablation of the ultraviolet light can cause the liquid crystal panel, liquid crystal plate life.LED light source: does not contain infrared ray, ultraviolet ray. The liquid crystal panel does not need heat dissipation design, and the light source has almost no influence on the liquid crystal panel. The influence of traditional light source on projector design: complex heat dissipation design, powerful fan, high voltage design, protection circuit, induction circuit, light path design are required.

LED light source: a surface light source composed of many LED. The intensity of single LED is lower than that of single traditional light source, but the strength of quantity and structure make up for the lack of luminous intensity. The light can be used directly or only through the Finel lens. Working voltage and temperature, traditional light source: hundreds or even thousands of volts, light source internal temperature of 1000 degrees.

LED light source: low voltage, can be as low as several volts, and even can be directly driven by dry cells, the operating temperature can be as low as room temperature. Traditional light source for heat dissipation and high voltage circuit: rigorous heat dissipation design, high voltage circuit.

DIY projector production is really strange, using LED light source as a projector, only DIY projector enthusiasts can think of it, using LED light source to do projector light source, you can not change the projection bulb for 5 years. What color is what color, warm love is warm, love is cold cool, pure love? No problem! All the products you want to source! Is the pure cold light, no ultraviolet, no infrared, low voltage power supply, what electric fan, what way, what temperature induction, what overload protection, not all to go to hell! It is the only drawback is the strength is not enough, however, the strength can be used to make up for the number one LED is not enough, 1000 enough?! the difference with the traditional LED light source projector lamp: the working principle of the traditional light sources: traditional projector light source is basically a single luminous body the point light source, high luminous intensity, light emitted from the light source, through the reflection bowl, condenser, Finel lens, can provide a liquid crystal panel use.

LED light source: in the case of high power, only a simple design of heat radiation is needed. The heat sink can solve the problem of heat dissipation. Without high voltage protection and temperature induction design, the light path design is greatly simplified. Maintenance cost traditional light source: complex heat dissipation design, powerful fan, high voltage design, protection circuit, induction circuit, light path design are required.LED light source: the light path after the light source can be all sealed without light path cleaning. Use of traditional light source: due to shorter life, higher use costs, the purchase price divided by the use of time, translated into 1 yuan / hour or so.LED light source: the light source life is longer than or equal to the projector life, and the cost is close to 0. Light source: 16*12=192 bright LED, each 3.3V, 20mA, total power of 13 watts, the power supply switch with the computer, the case of the load voltage will decrease, the measured voltage 11.04V, current 1.03A, net power limiting resistor consumption, the total power of the measured led shall not exceed 10 watts using LED light so! How do the benefits of the projector, so how do the projector effect? How do I fit the overhead projector? The whole projector is installed in the carton of a printer. It consists of four parts: LED light plate, a light source and a liquid crystal plate, a mirror, a liquid crystal plate and a lens,
