1, LED lamp LED light color points according
Press the LED light color points, can be divided into red, orange, green (subdivided green, standard green and pure green), blue and so on. Also, some light-emitting diodes include two or three color chips.
According to the light emitting diode at the doped or non-doped scattering agent, colored or colorless, the various colors of light-emitting diodes can be divided into colored, transparent, colorless and transparent, colored and colorless scattering scattering four types. Scattering of light-emitting diodes and LEDs used to do.
2, LED light emitting tube according to the smooth characteristics of
Press LED features a smooth cyclotomic lights, side lights, rectangular, surface LED, lateral pipe, surface mount miniature tubes. Divided by the diameter circular lamp φ2mm, φ4.4mm, φ5mm, φ8mm, φ10mm and φ20mm so on. Foreign usually referred to as a light emitting diode φ3mm T-1; the φ5mm is designated as T-1 (3/4); the φ4.4mm is designated as T-1 (1/4).
By the half-value angle size can be estimated round luminous intensity angular distribution. From the angular distribution of light intensity to be divided into three categories:
(1) high directivity. Generally pointed epoxy package, or package with a metal reflector cavity, and does not add scattering agent. Half-value angle of 5 ° ~ 20 ° or less, with a high directivity, can be used for local illumination light source or the light detector associated to form an automatic detection system.
(2) standard. Typically used for light, and its half-value angle of 20 ° ~ 45 °.
(3) the scattering type. This indicator is a larger perspective, the half angle of 45 ° ~ 90 ° or more, a large amount of scattering agent.
3, according to the structure of light-emitting diode
According to the structure of light-emitting diodes with full epoxy encapsulation, epoxy encapsulated metal base, ceramic base epoxy packaging and glass packaging and other structures.
4, according to luminous intensity and working current points
Press the luminous intensity and operating current, there are common brightness LED (light emitting intensity 100mcd); the luminous intensity between the 10 ~ 100mcd called high-brightness light-emitting diodes. General LED operating current to a few dozen mA mA, while the low-current LED operating current below 2mA (the same brightness and ordinary light tube).
In addition to the above classification methods, there by Chip Material classification and classified by function method
With the LED out of business in the 1960s, after decades of development has evolved over many, many species, the mainstream of the indices:
1) LED (Light emitting diode): We have a call LAMP LED products, there are call P2 products, but also call it plug the LED, anyway as long as the line are the property with one. And there is also many types of LED type:
Shape of colloid by: 3mm, 4mm, 5mm, 8mm, 10mm, 12mm, square, oval, tombstoning, there are some special shape, etc.;
Points by Lens Color: colorless, transparent, colored transparent, colored scattering, colorless scattering;
By color: red (red), orange (orange), yellow (yellow), yellow-green (green yellow), green (green), aquamarine (blue green), blue (blue), purple (pink), ultraviolet (uv), white (white), infrared, etc.;
2) SMD (Suface mount device): surface mount diodes or surface mount components are his called, which is also how in this category:
According to the shape and size of: 0603,0805,1210,5060,1010, etc., are generally smd diamond, so it is called are based on the size L * W is called, the industry use are inches, not millimeters, Also useful millimeters called, as 1608 (1.6 * 0.8mm) and so on.
Light color and colloidal species and LED products, but the shape of the product has undergone great changes.
3) Piranha (Flux led): This is the LED luminous efficiency due to use of vehicles can not meet their requirements, so we developed this product, is a small power products, the drive current is generally 50MA, general LED used 20MA, highest current can reach 70mA, because of its heat better, generally used in automobile taillights.
4) power (power led): existing LED lighting products, it has the following categories:
By the power points: 1w, 3w, 5w, etc.
Press the top-emitting lens points: flat head, condenser, glass shape
According to the process and the aluminum plate and the anti-luminous.
5) LED (Display): The earliest to do with the display and digital display used
By shape: 1, 2, 3, 4, etc.
Surface color: gray vinyl surface, but also have a black face white plastic, etc.
Polarity: common cathode, anode
The same color and the LED can do many kinds.
6) matrix (LED Dot Matrix): This product and digital control are similar applications in the information displayed. Their spacing and diameter of the holes are different products have changed, and now generally divided into 5 * 7 and 8 * 8, and its colors are monochrome, color, three-color and so on.
By color: one red, one green, two-color, three-color, etc.;
Press the hole diameter of: Φ2.0, Φ3.0, Φ3.75, Φ5.0, etc.;
Press Points Score: 5 * 7,8 * 8,16 * 16, etc.
There are other products: such as the pixels (cluster), metering source (LED Side Light Source), infrared receiver and transmitter products (Infrared & PhotoDiode) and so on.
Press the LED light color points, can be divided into red, orange, green (subdivided green, standard green and pure green), blue and so on. Also, some light-emitting diodes include two or three color chips.
