The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example 1

Fig. 1 shows an exploded view of a secondary reflection lamp of this embodiment, fig. 2 shows a cross-sectional view of the secondary reflection lamp of this embodiment, fig. 3 shows a schematic structural diagram of a screen of this embodiment, and with reference to fig. 1 to fig. 3, a secondary reflection lamp with a screen includes a lamp panel 1, a bracket 2, an LED light bar 3, a first reflection plate 4, a second reflection plate 5, and a screen 6, where the lamp panel 1 is used as a main frame of the lamp, a cavity 11 is formed inside the lamp panel, the cavity 11 is a mounting cavity, and the second reflection plate 5, the bracket 2, the first reflection plate 4, and the screen 6 are sequentially and fixedly disposed in the cavity 11 from bottom to top. The lamp panel 1 comprises a chassis 12 and a frame 13 on the periphery of the chassis 12, wherein the frame 13 comprises two long frame strips and two short frame strips which are fixed together in a riveting, screwing or welding mode, so that the integral structure of the lamp panel is formed. In the cavity 11, a power supply unit 7 is also mounted. The second reflection plate 5 is directly in contact with the chassis 12 and fixed above the chassis 12.

Specifically, the second reflection plate 5 of the present embodiment is a reflection aluminum plate having two arc-shaped reflection blades 51, that is, the second reflection plate 5 has a double-arc-shaped structure. The outer side 511 of the reflector leaf 51 is fixedly connected to the inner side of the lamp panel 1, while the inner side 512 of the reflector leaf is spliced together and fixed to the bottom of the lamp panel 1, specifically to the upper side of the bottom plate 12. The splicing structure of the reflecting blade 51 can be fixed together through the connecting piece 513, so that the structure is stable, and an effective reflecting arc surface is formed.

Above the second reflecting plate 5, the aluminum profile bracket 2 is provided, and the LED light bar 3 is fixed on the bracket 2. (the connection mode of the LED lamp strip 3 and the bracket 2 will be described later.)

Then, the first reflection plate 4 is fixed above the bracket 2, the reflection arc surface of the first reflection plate 4 faces the light emitting surface of the LED light bar 3, and meanwhile, the reflection arc surface of the first reflection plate 4 faces the reflection arc surface of the second reflection plate 5. Because the reflection cambered surface of the second reflecting plate 5 is larger than that of the first reflecting plate 4, the light emitted by the LED lamp strip 3 can be ensured to enter the second reflecting plate 5 for secondary reflection after being reflected by the first reflecting plate 4, and the emergent light can be directionally controlled to be totally reflected, so that the glare problem caused by direct light is avoided, and the glare-free lighting effect is achieved.

On the reflection cambered surface of first reflecting plate 4 and second reflecting plate 5, can set up reflection check (the area is the same or inequality), reflection check can be regular plate structure, and its cross-section can set up to triangle-shaped, quadrangle, pentagon or hexagon according to the needs of light path direction control, makes its control needs that satisfy light.

Therefore, the first reflecting plate 4 and the second reflecting plate 5 can further perform directional control on light, so that light control and light mixing of the LED light source are realized, the light is totally reflected, direct light and stray light are eliminated, the glare problem caused by the direct light and the stray light is avoided, and the illumination comfort is improved.

Above the first reflecting plate 4, a mesh 6 is provided so as to cover it. As shown in fig. 3, the mesh 6 includes a mesh portion 61 and bent portions 62, the mesh portion 61 is a main portion of the mesh 6, and the bent portions 62 are located at both sides of the mesh portion 61 for connecting the lamp panel 1.

It should be noted that, in the screen of this embodiment, the bent portion 62 is a sheet structure without meshes, so that diffuse reflection light can be blocked, and emergent light of a row-shaped shadow on a lamp panel can be avoided. The screen is different from the existing screens, the whole screen including the bending part is provided with the through hole, but irregular diffuse reflection light is emitted on the through hole, and the light emitting effect of the product is influenced.

The screen 6 is fixedly connected to the lamp panel 1 by a fastener 60 having an arc structure, and is erected above the bracket 2 and the first reflection plate 4, and there is some gap between the screen and the first reflection plate 4. In the actual installation process, the gap range can be adjusted according to the light control requirement.

Fig. 4 shows a schematic diagram of the combination of the bracket and the LED light bar in this embodiment, and as shown in fig. 4, the bracket 2 is an aluminum profile provided with a slot 21, the whole cross section of the bracket has a trapezoidal structure, and a heat dissipation cavity 22 is formed inside the bracket. Therefore, in this embodiment, the bracket 2 is provided with 3 slots, and correspondingly, 3 LED light bars are inserted into and attached to the slots 21. On the one hand, the light source device can be firmly and stably installed, and on the other hand, heat generated by the LED light bar 3 can be dissipated out through the heat dissipation cavity 22 in time.

According to the secondary reflection lamp with the screen, the first reflection plate and the second reflection plate are used for controlling the light emitting path of the LED lamp strip on the support, so that the emergent light rays are totally reflected, the glare problem caused by direct light is avoided, and the glare-free lighting effect is achieved; in addition, the screen with the protection function is additionally arranged, and because hole-free treatment is carried out on the bending part, light ray emergence is not influenced, so that the light emitting of the lamp is uniform, a good lighting effect is further ensured, and the lighting application requirement is met.

The foregoing is merely illustrative and explanatory of the structure of the present invention, which is described in more detail and with greater particularity, and is not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, many variations and modifications are possible without departing from the inventive concept, and such obvious alternatives fall within the scope of the invention.
