The invention is a method for arranging the position of the LED crystal on the lamp board, in particular, the optimal arrangement of the heat concentrated regions of each LED crystal without overlapping each other. And a light panel configured to configure the LED crystal by the method of arranging the position of the LED crystal on the light panel. And a luminaire comprising the aforementioned light panel.

Light-Emitting Diode (LED) is a kind of semiconductor electronic component that can emit light. In the early stage, due to the insufficiency of technology, only a single color and a low-intensity light source could be developed. The development of polar bodies has approached maturity, mostly in the field of lighting.

The light-emitting diode has the advantages of high efficiency, long life, not easy to break, and fast reaction speed, but the working temperature of the light-emitting diode often seriously affects the luminous efficiency, and wastes power to generate more heat. In addition to wasting power, the life of the light-emitting diode is shortened, so good heat dissipation measures are required.

In the prior art of the Republic of China Patent Publication No. 201202601 "Light-emitting diode lamps for uniform illumination of hollow bodies", a light-emitting device (40-40" for uniform illumination of curved, uneven or polyhedral surfaces is specifically mentioned. 45-45", 50-50", 60, 80, 93-93'''), which includes a plurality of flat panel connected LED modules (1, 11, 11', 21, 31, 41-41) , 46-46", 51-51", 61-61", 71-71", 81 1-81 8), which are at least paired adjacent to each other, wherein each board is connected to an LED module (1, 11, 11', 21, 31, 41-41", 46-46", 51-51", 61-61", 71-71''', 81 1-81 8) incorporating a plurality of illuminations Dipoles (4, 4', 14, 14', 24, 34, 64, 72). In addition, the Republic of China Patent Publication No. 201202601 relates to a light-emitting unit and relates to a use. According to the characteristics of the illuminating device (40-40", 45-45", 50-50", 60, 80, 93-93''') of the Republic of China Patent Publication No. 201202601, relative to the surface normal , at least one pair of adjacent boards are connected with LED modules (1, 11, 11', 21, 31, 41-41", 46-46", 51-51", 61-61", 71-71"', 81 1-81 8) Configure at an angle greater than 0°.

The above patent publication "Light-emitting diode lamp for uniform illumination of a hollow body" mentions in the content that in order to be able to arrange a relatively uniform light source on uneven, curved or polyhedron, special consideration is given to the LED on the substrate. The problem of locating the position is to avoid that the LEDs that are too close to each other cause the light sources to interfere with each other, thereby achieving better irradiance and uniform tolerance.

However, in the above patent case, only the irregular substrate surface is considered, but the arrangement of the LEDs on most of the substrate surfaces has not been discussed in detail, resulting in the fact that most of the lamps are randomly grown LED crystals, which cannot be effectively utilized. The illumination range of the LED crystal causes the illumination of a certain area to be brighter, and the illumination of some areas does not meet the lack of expectation.

In order to solve the lack of illuminance unevenness of the LED crystals implanted on the lamp panel, the inventors of the present invention have devised a method for arranging the position of the LED crystal on the lamp panel, comprising the following steps: illuminating a light panel according to an LED crystal When the working heat of the LED crystal is concentrated in the concentrated area of the lamp plate, a circular heat-acting zone is defined, the heat-acting zone has a boundary line; and the plurality of heat-acting zones are disposed on the lamp plate, the heat effect The regions are arranged in at least one ring shape with each other, and the boundary lines of the heat-acting regions do not overlap each other; the center position of the heat-acting region is set to a planting position for the LED crystal to be implanted.

Wherein, the working heat energy of the LED crystal is proportional to the distance from the planting position in the heat-acting zone, and the working heat energy of the LED crystal in the heat-acting zone is 75%-100 of the total working heat energy. %.

And, when the heat-acting regions are arranged in at least one of the most dense rings, the boundary lines of each of the heat-acting regions are in tangential contact with each other.

And the heat-acting zone detects the working heat energy of the LED crystals on the lamp board through an infrared sensor, thereby defining the heat-acting zone.

The method for arranging the position of the LED crystal on the lamp board in this embodiment has the following effects:

1. The method of the embodiment can effectively define the thermal active area of each LED crystal, and arrange the LED crystal on the light board according to the principle that the boundary lines of the heat-acting regions do not overlap each other, thereby avoiding the LED If the crystals are too close together, the heat cannot be effectively dissipated, which causes the LED crystals to affect each other and the life is reduced.

2. The principle that the boundary lines of the heat-affected zones do not overlap each other, so that the LED crystals of each other are not too close to each other, causing the light sources to interfere with each other, causing partial illumination to be brighter and partial illumination to be darker.

3. Through this method, the most appropriate number of LED crystals can be effectively implanted on a specific area of the lamp panel, which will not affect the light source or reduce the service life.

4. The lamp board to which the method of the embodiment is applied is circular, which is quite suitable for the shape of the lamp board commonly used in the market, and has good convenience.

Further, there is further described a lamp panel having a plurality of LED crystals disposed thereon, and the LED crystal systems are configured by the method of arranging the positions of the LED crystals on the panel.

The light panel of this embodiment has the following effects:

1. The LED crystals on the lamp board do not shield each other from the light source, and the working heat energy does not affect each other. More importantly, the LED crystals are arranged in a ring shape to facilitate the wiring between the subsequent LED crystals. Effectively reduce the amount of silver glue used.

And a lamp comprising: a lamp holder having a groove portion; a lamp plate disposed on the lamp holder, wherein the lamp plate is provided with a plurality of LED crystals, and the LEDs are It is configured by the method of arranging the position of the LED crystal on the lamp board as described above.

The lamp of this embodiment has the following effects:

1. The LED crystals in the lamp are not interfered by adjacent heat sources, which can effectively prevent the service life from being shortened. Moreover, the illuminance exhibited by the luminaire is also fairly uniform, and there is no local particularly bright or particularly dark situation.

The first figure is a flowchart of the method for arranging the position of the LED crystal on the lamp board of the present invention. The following steps are illustrated: when an LED crystal emits light on a light panel, the working heat energy of the LED crystal defines a circular heat-acting region on the concentrated area of the light panel, and the heat-acting region has a boundary line. Further, the heat-acting zone defined by any LED crystal is the working heat energy generated by the outward emission of the LED crystal, and the farther away from the LED crystal, the lower the working heat energy occurs; the same distance from the LED The farther the crystal is, the higher the working heat energy that occurs.

Next, a plurality of the above-mentioned heat-acting regions are disposed on the lamp board, and the heat-acting regions are arranged in at least one ring shape with each other, and the boundary lines of the heat-acting regions do not overlap each other.

Setting a center position of the heat-acting zone as a planting position for the LED crystal to be implanted, the farther from the LED crystal being described, the lower the working heat energy generated, and the LED crystal The higher the working heat energy occurs, the higher the working heat energy is, the difference between the working heat energy of the LED crystal and the distance from the planting position in the heat-acting zone is the same. It is further explained that the working heat energy of the LED crystal in the heat-acting zone is 75% to 100% of the total working heat energy.

In the first embodiment, the heats are The boundary line (211A) of the active area (21A) is in tangential contact with each other, but is not limited thereto.

Finally, the center position of the heat-acting zone (21A) is set to a planting position (212A), and the planting position (212A) is used for planting the LED crystal (2A), thereby completing the most appropriate arrangement, avoiding each The interaction of the working heat energy radiated by the LED crystal (2A) causes the loss of the service life of the LED crystal (2A), and also prevents the illumination between the LED crystals (2A) from being shielded from each other, resulting in insufficient illumination in a local area. occur.
