What reason is caused Dead lights of LED point light source lamp？ For details, see below.
The leakage current of LED point light sources are caused by excessive PN junction failure.In generally LED chips are injury by static electricity, the PN junction LED chip failure, leakage current increases,the LED light source will turn into a resistance, this usually does not affect the LED point light source and other work. which generally does not affect the work of other LED point light sources.Prevent electrostatic damage to electronic components, is a very important work of the electronics industry, LED packaging, application of the enterprise must not be taken lightly.  Any one part of problem, will cause damage to the LED light source, LED light source to the bad performance or even failure.LED spot light lamp wiring open solder joints causing death.LED point light source connection solder joint make Dead lights by Open circuit of light.Internal connection wire of LED point light source is disconnected,resulting in the death produced when not have current inflow of the LED lights, this situation will affect the normal work of other LED light source, the reason is the low voltage operation of LED light source, the general should use string, parallel to join, to adapt to different operating voltages, More series of LED light source draw the influence of LED light source series.can use a weld method In such a situation,Will not bright LED light source with a lighter LED lead is heated to 200-300 ℃， remove the lighter, with 3-volt button batteries connected LED by positive and negative,  if LED light source can be light, but with the lead temperature reduced By the light turns the not bright, which proves that LED point light source is weld.the reason of Heating can light is based on the principle of metal thermal expansion and contraction, elongation and internal solder connected with the expansion of LED lead when heated, when the power is switched on, the LED point light source can be a normal lighting.The two way cause of Dead lights phenomenon of LED point light source lamp. But only to comply with the using rules of LED point light source, the above two phenomena can be avoided.

The micro projector, since the second half of 2008 into mass production, liquid crystal on silicon (LCoS) and TI (Texas Instruments) independently developed the digital light processing (Digital Light Process; DLP),there are two technical, and called the mainstream for micro projection technology. At present, two kinds of micro projection technology using LED as the light source, in LED mass production
as the LED production of the high ability of mass production manufacturers more and more, the cost is also continued to decline. Among them, the LCoS micro projection technology can be used for white light LED with color filter, effectively reduce the micro projector costs, and enhance the penetration rate.

In 2010, with the consumer electronics market is gradually recovering, terminal manufacturers and consumers of micro projector technology requirements will be more strict. Therefore micro projector quality development will have three major trends, including brightness upgrade, the resolution improvement, and improved color performance.

In order to improve the luminance, LED vendors are increased the LED luminous efficiency year by year white LED with a color filter, although the advantage of reducing costs, but inevitably affect the color performance, so LCoS pico projectors terminal manufacturers have shift to RGB Full color LED pixel light source. As for the resolution, although decided by the panel side in theoretically , but if the brightness of less than a certain standard, then high resolution panel, is immune to the appropriate display.In addition to LED, the laser also has bigger opportunity for mini projector light source potential. At present, although there have been a variety of new micro projection technology with laser light source, but only American Microvision alone developed the two-dimensional scanning MEMS micro-projection technology has been introduced into mass production in early 2010.
Although the laser light collimation good because without merit manual focus, but will thus cause the laser spot (Speckle) phenomena affect the quality, though not not be solved, but still big trouble.
In addition, the current due to the green laser into volume production time soon, and only American Corning (Corning) can be mass production, the price is expensive,  so with laser in the mini projector light source to achieve popularity may have more than 2 years.

The Diffused LED Pixel Module can be used to draw a target point with cast light, the distribution of light have isotropic properties, spotlight and web three options.The function and target of The Diffused LED Pixel Module light source is same whit light source of target.  just not the target point, the user can change the direction of the light. Similarly, the free light also has above three kinds of light control light distribution properties. Line source is also divided into goal line source (Target Linear) and free line source (Free Linear)  two types.
Target line can be used to cast light source to a target object, which has a diffuse light distribution properties (Diffuse) and mesh (Web) two kinds. Freedom line source function and target line light sources, but no target object, the user can change the direction of the light.

The same free linear LED point light source also has above two kinds of spectrophotometric control properties of light distribution. Wherein the diffuse distribution of the light will be the greatest at an angle to the surface of the projection light intensity, as light intensity decreasing angle of tilt， Web distribution type allows users to customize the intensity of the light emitted.

Basic knowledge of LED Testing Technology
The forward voltage: through the forward current of light emitting diode in order to determine the value, the voltage drop generated in the polarization .

Reverse current: in order to determine the value of the reverse voltage across the light-emitting diode (when the current flowing through the light emitting diode).

The peak wavelength: power maximum of spectral radiant.

Half intensity angle: the luminous (or radiant) intensity distribution, luminous (or radiant) luminous intensity is greater than or equal to the maximum intensity constituted half angle.The dominant wavelength: any color can be looked at as a spectral color, according to a certain proportion and a reference light source (such as the CIE standard light source A, B, C, etc. can source E standard illuminant D65) phase mixing and matching color coming out, the main wavelength of the spectral color is the color. Dominant wavelength is equivalent to the human eye observation to color palette (mental capacity). If you have obtained the chromaticity coordinate measured LED device, can use to white E light source (x0=0.3333, y0=0.3333) as a reference to calculate the main wavelength and determines the color of the light source. Calculation based on a chromaticity diagram connection reference slope straight line light source color point and the sample color chroma point of intersection line, look-up table read and spectral locus, determine the main wavelength.

The average intensity of light source: ratio of units in a given direction on a solid angle element is contained within a small flux D Phi V and the solid angle of D Candela (CD)

Radiation bandwidth: spectral radiant power is greater than or equal to the maximum value of half the wavelength interval

LLZ the principle of infrared, infrared remote control has been widely used in home appliances and industrial control system, understand their work principle and performance, further made the infrared remote control system, also is not difficult.
characteristic of infrared eye can see the visible light wavelength, according to arrangement, in turn (from long to short) for the red, orange, yellow, green, cyan, blue, purple, as shown in figure
1. Can be seen from the graph, the red light in the wavelength range of 0.62μm ~ 0.76μm, longer than the red wavelength light is infrared. Infrared remote control is the use of wavelength of 0.76μm ～1.5μ m near to transmit a control signal. Mainly Feature of Infrared is that it does not interfere with other electrical equipment, it will not affect the surrounding environment. the Circuit debugging simple, if the transmitted signal code, can realize the function that multi-channel infrared remote control.
2 Infrared remote control system of infrared emitting and receiving
people see consists of transmitting and receiving the two part. The emission component parts for infrared emitting diode, it emits infrared rather than visible light, as shown in figure
2.Common infrared wavelengths emitted from the light emitting diode is about 940nm, the shape and the ordinary 5 mm light emitting diode is the same, but different colours. In general there are transparent, black and dark blue three. Method for judging the quality of infrared light emitting diodes is same with ordinary diode.emitting power of the infrared light emitting diodes is about 100mW. Luminous efficiency with a special instrument for determination, on amateur conditions, can rely on the experience with the distance of roughly determination method. The infrared receiving tube receiving circuit is a photosensitive diode, when used for infrared receiving diode reverse bias voltage is applied, it can work normally and obtain high sensitivity.How it works: infrared photosensitive resistance is actually a resistance.in a high impedance state is close to the 6K when not have infrared lighting. completely avoid the light may not only, The mainly parameter of Infrared LED(receiving module) as follows:
work voltage：4.8～5.3V
work currently：1.7～2.7mA
receive frequency：38kHz
peak value of wavelength：980nm
static state of output：High level
low level of output：≤0.4V
high level of output：VDD voltage
The infrared receiving diode are generally circular and square two. Because the transmitting power of the infrared light emitting diodes are small, weak signal received by the infrared receiving diode, so the receiver will increase the high gain amplifier circuit.
