Detailed Description

In order to make the technical means, the creation features, the achievement objectives and the functions of the present invention easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to 3, the technical scheme adopted by the embodiment is that the ultra-low glare mining lamp reflective cup structure comprises a PCB (1), lamp beads (2), a built-in reflective cup (3) and an outer reflective cup (4), and is characterized in that the PCB (1) is a circular circuit board in a stepped design, and a plurality of lamp beads (2) are equidistantly distributed on each step; each lamp bead (2) on the PCB (1) is provided with a built-in reflection cup (3); the outer reflection cup (4) is sleeved outside the PCB (1); the overall thickness of the PCB (1) is between 8mm and 16 mm.

The micro-structure design of the inner surface of the outer reflecting cup (4) can be diamond, hexagon, square, rectangle or scaly nail.

Wherein, the curvature of the microstructure on the inner surface of the outer reflecting cup (4) can be adjusted and designed before production.

When the built-in reflection cup (3) is installed, the refraction surface of the built-in reflection cup is outward and faces the inner side of the outward reflection cup (4).

The present embodiment is described by taking the above scheme as an example and combining fig. 4.

There are two types of commonly used reflective cups on the market at present; the first type is a COB reflective cup, and the second type is a medium-power integrated reflective cup. Referring to fig. 5, wherein its grading principle of COB reflection of light cup be a COB light source collocation reflection of light cup carry out the grading, the light that the COB light source sent divide into two parts: the light rays of the first part deviating from the normal of the COB light source are emitted to the reflecting cup and then reflected to the target receiving working surface through the reflecting cup; the light of the second part deflected to the normal of the COB light source is not influenced by the reflecting cup but directly irradiates the target receiving working surface; the light of the second part, which is deviated from the normal line of the COB light source, is not controlled, so that the light of the second part cannot be distributed. This part of the light will be directed towards the human eye, which causes a very unpleasant glare due to the very high brightness of the LEDs. And the second part of the light cannot be optimized to the optical angle we want due to the uncontrolled optical angle of this part of the light.

The light distribution principle of the second medium-power integrated light source reflective cup is that a medium-power integrated light source is matched with a reflective cup for light distribution, referring to fig. 6, light emitted by the medium-power integrated light source is divided into two parts: the light rays of the first part deviating from the normal of the medium-power integrated light source can be emitted to the reflecting cup and then reflected to the target receiving working surface through the reflecting cup; the light rays of the second part deflected to the normal of the middle power integrated light source are not influenced by the reflecting cup but directly irradiate the target receiving working surface; the light rays of the second part deflected to the normal of the middle power integrated light source are not controlled, so that the light rays cannot be distributed. This part of the light will be directed towards the human eye, which causes a very unpleasant glare due to the very high brightness of the LEDs. And the second part of the light cannot be optimized to the optical angle we want due to the uncontrolled optical angle of this part of the light. However, because the energy distribution of the medium-power integrated light source is relatively dispersed with respect to the energy distribution of the COB light source, the glare degree is slightly weaker, but the ideal requirement of low glare is not met.

Through the description above, the built-in reflection cup is configured for the lamp bead to convert a point light source into a surface light source and convert a small-area light emitting surface into a large-area light emitting surface, so that the glare value index is remarkably reduced; wherein the integral optical angle of the combination of the built-in reflecting cup and the outer reflecting cup can be between 30 degrees and 90 degrees; the PCB is a stepped design PCB with the thickness of 8mm-16mm, the number of turns and the number of the lamp beads on the PCB can be changed during production according to actual use requirements, so that the optimal use state is achieved, and the lamp beads distributed at equal intervals can uniformly release heat generated in work; the optical section of the built-in reflection cup is a free spline curve or a high-order equation curve to ensure that the whole reflection cup is a circularly symmetric annular surface, so that part of light which is not incident into the outer reflection cup is reflected onto the outer reflection cup through the optical section, and the light is ensured not to be directly incident into a target receiving surface or human eyes to cause glare or other problems; it is worth mentioning that the utility model discloses can also further adjust the degree of consistency and the size of optics angle through the micro-structural design of designing outer anti-light cup internal surface.
