Referring to fig. 1 and 2, in one embodiment, a lamp for uniformly emitting light includes a base 11, a light source device 12 disposed on the base 11, and an inner transparent member 13 disposed above the light source device 12.

The inner transparent member 13 has a plurality of protrusions 131 formed on a surface thereof away from the light source 12, and the outer surface of the protrusions 131 is curved. The light source 12 in this embodiment may be an LED lamp bead.

In this embodiment, by forming the protrusion 131 on the surface of the inner transparent member 13 away from the light source element 12 and setting the outer surface of the protrusion 131 to be a curved surface shape, light emitted from the light source element 12 is refracted by the protrusion 131 on the inner transparent member 13, and the divergence angle is expanded and then transmitted to the outside. Because the light emitted by the light source 12 is refracted by the protrusion 131 on the inner transparent member 13, the light emitted by the light source 12 is emitted uniformly along the surface of the protrusion 131, so that people do not feel dazzling or dizzy, and the lighting experience is improved.

Referring to fig. 1-5, in one embodiment, the protrusions 131 are elongated, and the light source devices 12 are linearly arranged on the base 11, and the light source devices 12 are located on the central axis of the inner transparent member 13. The light source is a point light source, and a plurality of point light sources are arranged into a strip shape matched with the bulges. Or the light source piece is a strip shape matched with the bulge. In this embodiment, the light source 12 is linearly arranged on the central axis of the inner transparent member 13, and the outer surfaces of the light source 12 and the protrusion 131 are in a shape matching with a curved surface, so that the light emitted by the light source 12 is uniformly distributed to two sides of the central axis of the inner transparent member 13, and the refracted light is more uniform. In another embodiment, the protrusion 131 may be hemispherical, and the light source 12 may be a point light source or an annular light source.

In one embodiment, the protrusions 131 are axisymmetric lens structures, and the protrusions 131 are gradually thicker from the middle to both sides, so that the light emitted from the light source device can be diverged.

The equation of the curve of the section of the outer surface of the protrusion 131 along the length direction of the inner transparent member 13 is:

please refer to fig. 6 for an image of the equation of the curve. It should be noted that the coordinate system of the curve equation L of the cross section of the protrusion 131 is a straight line perpendicular to the bottom end surface of the inner transparent member and perpendicularly intersecting with the straight line of the central axis of the bottom end surface of the inner transparent member, which is the y-axis, and the direction from the outer surface of the inner transparent member to the bottom end surface is the forward direction. The x-axis is perpendicularly intersected with the y-axis and perpendicularly intersected with a straight line of a central axis of the bottom end surface of the inner transparent member. Fig. 7 shows a light distribution curve obtained by refracting the light emitted from the light source through the inner transparent member.

Preferably, the addition ratio of the diffusion powder is 0.2 to 0.4% of the total mass of the outer transparent member. The diffuse reflection effect of the diffusion powder makes the light passing through the outer transparent member 14 more uniform and softer, and has both an aesthetic and anti-glare effect, and the higher the concentration of the light scattering powder, the more uniform the effect is, the better the effect is.

Clamping protrusions are arranged on two sides of the base 11. The two ends of the base 11 are provided with end covers 15, and one end of each end cover 15 is provided with a clamping groove 151.

The engaging protrusion is in interference fit with the engaging groove 151 through the first side wall 1111 and the second side wall 1112.

A transition plate 152 is arranged between the base 11 and the end cover 15, a threaded hole is arranged on the transition plate 152, and the threaded hole corresponds to the dividing groove 112 and the clamping groove 151. The transition plate 16 and the base 11 are fixed by bolts 153. The bolt 153 penetrates the threaded hole and is in interference fit with the partition groove 112.

Interior transparency comprises the transparent holding tank of one by one, can hold the LED lamp pearl of the different quantity of different models in the holding tank, if can hold a plurality of 2835, 3030, 3535 encapsulation size's LED lamp pearl, the light that LED lamp pearl sent is through interior transparency refraction expand after the divergence angle, pass through outer transparency again, because the effect of interior lens, the even dark spot that does not have in surface of outer transparency during the light-emitting, outer transparency adds the diffusion powder, can make light softer, the light homogeneity that LED lamp pearl sent is better, and have better anti-dazzle effect. The outer transparent piece is uniformly added with diffusion powder according to a curve equation L of a curve equation of a section of the bulge corresponding to the accommodating groove, the adding proportion is 0.2% -0.4%, the light passing through the outer transparent piece 14 is more uniform and softer due to the diffuse reflection effect of the diffusion powder, the appearance and the anti-dazzle effect are achieved, and the higher the concentration of the diffusion powder is, the more uniform the effect is, the better the effect is.

Specifically, the lamp bead with uniform light emission of the embodiment adopts 3030 with a color rendering index of 80 to package an LED, and the total power is 36W. Three LEDs are placed in a containing groove, the whole inner transparent piece is composed of a plurality of containing grooves, the LEDs are refracted by the inner transparent piece, the light distribution of the LEDs is changed, the light-emitting angle is enlarged, and the outer transparent piece with the diffusion powder is added to the rethread, so that the milky outer transparent piece is bright and uniform, the light-emitting bright spots of the LEDs cannot be seen completely, and the light-emitting area is enlarged. Meanwhile, the diffuse reflection effect of the diffusion powder enables the luminous surface to be softer, and the diffusion powder has the effects of attractiveness and anti-dazzle.

Thus, the working principle of the lamp with uniform light emission in the embodiment is described.

According to the invention, the protrusion is formed on one surface of the inner transparent piece far away from the light source piece, the outer surface of the protrusion is arranged in a curved surface shape, and light emitted by the light source piece is refracted by the protrusion on the inner transparent piece, so that the divergence angle is enlarged and then is transmitted to the outside. Because the light emitted by the light source part is refracted by the bulges on the inner transparent part, the light emitted by the light source part is uniformly emitted along the surfaces of the bulges, the dazzling or dizzy feeling of people can not be generated, and the lighting experience is improved.
