Example Embodiment

[0044] Example 1:
[0045] Such as figure 1 As shown, the lamp module of this embodiment includes a base 1, an LED aluminum substrate 2 and an LED lens module 3.
[0046] Wherein, the base 1 has an upper surface and a lower surface that are parallel to each other, and the upper surface and the lower surface are both quadrangular. The base 1 also has four sides, each of which is a flat surface and includes A pair of opposite sides parallel to each other in the upper surface and the lower surface. And in this embodiment, the four side surfaces are all inclined surfaces, and the value of the complementary angle of the dihedral angle between each inclined surface and the upper surface is the same, and the specific value range is that of the light source The value of the light intensity in the light distribution curve is the angle corresponding to two-thirds of the central light intensity of the light distribution curve to ninety degrees. In this way, the shape of the base 1 is specifically an inverted prism.
[0047] There is a groove 11 at the center of the base 1, the LED aluminum substrate 2 is fixed in the groove 11 by bonding or other connection methods, and the groove 11 has a through hole 12 in the center for realizing the LED The wiring of the aluminum substrate 2.
[0048] At least one single-color color light LED 21 capable of current adjustment is fixed on the LED aluminum substrate 2. In this embodiment, four single-color LEDs are fixed, and the color of the LED can also be any unit color. The full-color light can be adjusted arbitrarily, and the four monochromatic LEDs are a red LED, a green LED, a blue LED and a white LED. The light wires of each LED can pass through the through hole 12 and then be connected to the control circuit (not shown in the figure) under the base 1.
[0049] A lens module 3 composed of a plurality of reflective cups 31 is also fixed on the aluminum substrate 2, wherein the number of the reflective cups 31 is the same as the number of LEDs on the aluminum substrate 2. The lens module 3 covers the LEDs on the aluminum substrate 2 from above. In addition, four positioning holes 22 are provided on the aluminum substrate 2, and four positioning corners 32 are provided on the lens module 3. In this way, by buckling the positioning hole 22 and the positioning corner 32 to each other, a pixel spot can be accurately positioned. The structure of the lens module 3 is as follows figure 2 Shown.
[0050] The lens module 3 can accurately mix the light emitted by the four single-color LEDs 32, and by adjusting the current of each LED separately, their brightness can be changed, so that the mixed light can be Achieve full-color changes. At the same time, in order to ensure the light reflection effect of the lens, the material of the lens module 3 can be made of acrylic or polycarbonate. Of course, the working principle and material composition of the lens module 3 belong to the well-known technology in the field. No longer. While realizing the light mixing function of multiple LEDs, it can also realize the adjustment of color temperature and color rendering index, and by mixing white light into the color light, the color rendering index can be effectively increased, so that the color rendering property can be increased to 90 %the above.
[0051] In this way, through the combination of the above-mentioned LED aluminum substrate 2 and the lens module 3, while realizing the lighting function, the full-color change of the light can also be realized.
[0052] See image 3 The lamp of this embodiment is formed by splicing five lamp modules, and the light emitting direction of the light source in each lamp module of the lamp is the same as the connecting direction from the center of the lower surface to the center of the upper surface, and At least one of the inclined surfaces is included in the contact surfaces of every two lamp modules in contact.
[0053] According to the common knowledge in the field, when the light intensity in the light distribution curve of the light source is two-thirds of the central light intensity, this is the maximum light that enables the two adjacent pixels to be distinguished by the human eye. Strong, that is, if the light intensity value is less than two-thirds of the central light intensity, the adjacent pixels can be distinguished. If the light intensity is greater than two-thirds of the central light intensity, the adjacent pixels cannot Be distinguished.
[0054] It can be determined by referring to the light distribution curve of the light source that the value range of the complementary angle of each dihedral angle between the inclined surface and the upper surface is the value of the light intensity in the light distribution curve of the light source When the angle corresponding to two-thirds of the central light intensity of the light distribution curve reaches ninety degrees, the lights emitted by the two adjacent lamp modules can be separated in the far field, and thus can be distinguished.
[0055] In the specific implementation process, the splicing method of every two lamp modules in contact with each other in the lamp may adopt bonding, welding, clamping or screwing.

Example Embodiment

[0056] Example 2:
[0057] Such as Figure 4 with Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that: in this embodiment, the upper surface and the lower surface of the base 4 of the lamp module are both triangular, and the base 4 also has a groove 41 and a through hole 42, which The functions of the groove 41 and the through hole 42 are the same as the functions of the groove 11 and the through hole 12 in the first embodiment, and will not be repeated here. The lamp in this embodiment is formed by splicing four lamp modules, and the three side faces of each lamp module in this embodiment are also inclined surfaces, and each inclined surface is between the upper surface The value range of the complementary angle of the dihedral angle is also when the light intensity in the light distribution curve of the light source is two-thirds of the light intensity at the center of the light distribution curve. . Therefore, the lamp of this embodiment can also realize full-color arbitrary adjustment of the emitted light and separate the lights emitted by different lamp modules in the far field.
[0058] Of course, in the specific implementation process, the upper surface and the lower surface of the base of the lamp module can also be set to other polygons with the same number of sides at the same time, such as pentagons, hexagons, etc. at the same time. Preferably, it can be Regular polygon.

Example Embodiment

[0059] Example 3:
[0060] The difference between this embodiment and Embodiment 1 is that: in this embodiment, the lamp is formed by splicing at least one first lamp module and at least one second lamp module.
