[0021] In the following, the utility model is further described in combination with the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined to form new embodiments without conflict.
[0022] Embodiment:
[0023] Please refer toFigure 1 The lens of the large-angle light distribution of the culture lamp of the embodiment comprises a shell, an aluminum profile radiator 7, a light source 9, and a driving power supply 3. The shell comprises a PC diffusion lens 1 and a base 2, which are arranged in an upper and lower manner and are integrally formed. The aluminum profile radiator 7 is installed inside the shell. The outer profile of the aluminum profile radiator 7 is trapezoidal, and the wall thickness is uniform. The inside of the aluminum profile radiator 7 is a hollow trapezoid. A groove is arranged in the middle of the two waists of the aluminum profile radiator 7. The light source 9 is symmetrically inserted into the groove arranged in the middle of the two waists. The driving power supply 3 is fixedly installed in the cavity between the bottom side of the aluminum profile radiator 7 and the bottom of the shell.
[0024] The shell is a symmetrical structure on the left and right sides. The cross section of the PC diffusion lens 1 area on each side is composed of four circular arcs connected in a head-to-tail manner. The radius of the four circular arcs from top to bottom is r4 > r3 > r2 > r1, and the thickness of each circular arc is consistent.
[0025] The light source 9 comprises a strip-shaped metal substrate and a patch LED lamp bead. The patch LED lamp beads are uniformly and interval arranged along the length of the strip-shaped metal substrate. The light emitting angle of the patch LED lamp bead is 120° standard Lambert body.
[0026] The upper bottom edge of the aluminum profile radiator 7 is designed with an extension edge on each side.
[0027] The distance d1, d2, d3 between the patch LED lamp bead and the PC diffusion lens is greater than 0.9d and less than 1.1d. The d is the average value of d1, d2, and d3. The maximum light intensity is in the direction of d2. In this way, the angle of the central light intensity of the whole lamp is limited. After light diffusion, the light intensity A10 = light intensity B6 > light intensity C8.
[0028] The width of the base gradually shrinks from top to bottom. The two sides are symmetrical arc surfaces C1 and C2. The bottom surface is a plane, which is convenient for mounting and adhering to the wall surface. It is also suitable for ceiling mounting. The rope can also be fixed on the ceiling mounting bracket. The outer side of the arc surface C1 and the arc surface C2 is provided with a groove 4, which can install a fixed clip. After installation, only the lens area with uniform light can be seen from the front, and other areas can be hidden to form visual aesthetics.
[0029] The inner side of the arc surface C1 and the arc surface C2 is provided with a clamping groove 5. The aluminum profile radiator is inserted into the clamping groove for positioning.
[0030] Specifically, the lamp is composed of four parts, the outer part is the shell of the lamp, the upper part of the shell is a milk white PC diffusion lens, the lower part is a pure white PC base, the two parts are combined into one and cannot be separated, are extruded by the same mold, and have the same thickness, the middle part is an isosceles trapezoidal aluminum profile radiator 7, the outer contour is trapezoidal, the wall thickness is uniform, the inside is a hollow trapezoid, which is designed according to the chimney heat dissipation principle, the third part is a light source 9, long strip light sources are respectively inserted into the slots in the middle of the two sides of the aluminum profile radiator, the two light sources are symmetrical, the light emitting angle of the light source LED is 120° standard Lambert body, the strongest light intensity of the light source is perpendicular to the two sides, after the diffusion of the two light sources through the shell lens, a uniform large-angle light beam angle is formed, and the illumination range is larger, as shown in Figure 5 The light source light range covers the lens area away from the light source at a distance substantially equal to the distance, and the fourth part is a driving power supply fixed in the cavity between the back of the aluminum profile radiator and the bottom of the shell by screws.
[0031] The upper bottom edge of the aluminum profile radiator is respectively designed with a transversely extended edge on both sides, the extended edge part can block the irradiation of the lower light source light to the central area, which is beneficial to the reflection of the light to the two side areas of the lamp, and a larger diffusion angle is formed.
[0032] The shell is a left-right symmetrical structure, the shell lens area is made of PC material + diffusion powder, and is white and diffused, as shown in Figure 2 The light source irradiates from the inside, and the external light can form a diffuse reflection effect, and the light distribution curve is an apple-shaped curve, compared with the light distribution curve of the traditional lamp shown in Figure 4 It can be seen that the application makes the irradiation surface more uniform and the irradiation area larger.
[0033] In order to maintain the ideal scattering effect, the distances d1, d2 and d3 satisfy 0.9d Figure 3 As shown in
[0034] The above-mentioned embodiments are only preferred embodiments of the utility model, and cannot be used to limit the scope of protection of the utility model, and any non-substantial changes and replacements made by those skilled in the art on the basis of the utility model all belong to the scope of protection required by the utility model.
