A polarized reflective cup floodlight

Abstract

The present invention relates to a polarized reflector floodlight. The angles of the aluminum reflectors used on LED lamps on the market are all greater than 90 degrees, and they do not play a role in expanding the LED light-emitting angle. Among them: the lamp housing, the aluminum substrate, and the reflector module are fixedly connected in sequence by fixing screws, the surface of the aluminum substrate is fixedly mounted with LED lamp beads, and square holes adapted to the LED lamp beads are provided on both sides and the middle of the reflector module. The reflector module adopts a hexagonal honeycomb arrangement. After assembly, it is sealed by gluing with tempered glass, and the lamp housing and the mounting bracket are fixed by hexagonal screws. The advantages of this device are that the number of LEDs is distributed in a certain proportion and is placed at an angle to the horizontal. The position of the reflector is different from the front and back, left and right four-sided angles. The hexagonal honeycomb arrangement is adopted through optical simulation software. While strengthening the strength of the reflector, the light emitted by the LED is reflected after passing through the scales on the reflector surface, and the light is more orderly, achieving uniform light density on the illuminated surface.

Description

Technical Field

[0001] The present invention relates to the technical field of LED lighting, in particular to a polarized reflective cup floodlight. Background Art

[0002] Currently, the secondary optical implementation of LED floodlights is LED + aluminum reflector or LED + lens to achieve the required luminous angle and uniformity of the illuminated surface.

[0003] In the case analysis of LED+aluminum reflector, the LED chip has a 90-degree luminous angle and the central light intensity is relatively concentrated. Due to process problems, the angle of the aluminum reflector used in LED lamps on the market is greater than 90 degrees, which does not play a role in expanding the LED luminous angle. The decorative effect is greater than the practical effect.

[0004] Through the secondary optical case study of LED + lens, the light emitted by the LED is refracted by the lens material, distributing the light within the required angle, resulting in a uniform light distribution curve. The disadvantage is that the brightness of the light-carrying surface of the lens is too high, which is significantly different from the surrounding brightness. This leads to significant glare and reduces eye comfort. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art. The present invention provides a polarized reflective cup floodlight to solve the above problems.

[0006] The technical solution of the present invention:

[0007] A polarized reflector cup floodlight comprises a lamp housing, an aluminum base plate, a reflector module, LED lamp beads, fixing screws, tempered glass, a power supply, hexagon socket screws, and a mounting bracket; wherein: the lamp housing, the aluminum base plate, and the reflector module are fixedly connected in sequence by fixing screws, the LED lamp beads are fixedly mounted on the surface of the aluminum base plate, square holes adapted for the LED lamp beads are opened on both sides and the middle of the reflector module, the reflector module adopts a hexagonal honeycomb arrangement, a power supply for lighting the LED lamp beads is installed at the bottom of the lamp housing, and after assembly, the lamp housing is sealed by gluing with tempered glass, and the lamp housing and the mounting bracket are fixed by hexagon socket screws.

[0008] Furthermore, the reflector module includes a top mounting hole, a bottom mounting hole, a first side cover (front direction), a second side cover (rear direction), a side cover (left and right directions), and a bottom cover. The reflector module is provided with a top mounting hole at the top and a bottom mounting hole at the bottom. The angle between the first side cover and the bottom cover is 130°, the angle between the second side cover and the bottom cover is 120°, and the angle between the side cover and the bottom cover is 120°.

[0009] Furthermore, the LED lamp beads are discharged in the middle and on both sides, and four LED lamp beads are placed on each side cover. The light emitted by the LED lamp beads is reflected by the reflectors on both sides (i.e. the side covers on the left and right sides of the reflector) to achieve a light distribution angle of 143°.

[0010] Furthermore, the first side cover and the second side cover (i.e., the side covers in the front and rear directions of the reflector) control the light emitted by the four LED lamp beads on both sides and the four LED lamp beads in the middle, achieving a light distribution angle of 68° and a polarization angle of 8°.

[0011] Furthermore, the mounting bracket is bent in a straight-line folding manner and an oblique folding manner.

[0012] The advantages of the present invention are:

[0013] 1. The reflector module adopts a hexagonal honeycomb arrangement through optical simulation software. While strengthening the reflector strength, the surface curvature of the hexagonal honeycomb further optimizes the light emitted by the LED lamp beads, so that the light emitted by the LED lamp beads is reflected after passing through the scales on the reflector surface, the light is more orderly, and the light density of the illuminated surface is uniform.

[0014] 2. The LED lamp beads are discharged in the middle + on both sides. Part of the light passes through the glass directly, and part of the light is reflected by the reflector and then passes through the glass. The intensity of the light passing through the glass is more uniform, there is no strong light spot on the glass, which reduces glare and increases eye comfort.

[0015] 3. The LED lamp beads on both sides are placed at an angle to increase the projection angle. The angle of the horizontally placed LED is only 90 degrees.

[0016] 4. The included angle between the front and rear side covers of the reflector module forms a polarized light projection angle, which directs more light to the position where light is needed, and has a higher utilization rate.

[0017] 5. The LED lamp beads are evenly arranged, the heat distribution is more reasonable, and it is easy to dissipate heat. Unlike conventional reflective cups, the LED lamp beads are concentrated together, causing excessive local heat. BRIEF DESCRIPTION OF THE DRAWINGS
