Description

Technical Field

[0001] This utility model belongs to the field of street light technology, specifically relating to a novel street light module that can improve luminous efficiency. Background Technology

[0002] Existing LED street light modules are assembled from heat sinks, lamp panels, lenses, and waterproof lines. The luminous efficacy of an LED street light module is mainly determined by the efficiency of the power supply, the luminous efficacy of the LED chips themselves, and the light transmittance of the lens. The power supply, LED chips, and lens components are fixed at the factory. The lens is mainly made of PC transparent material with a light transmittance of 90%. When the light from the LED chips passes through the lens, some loss occurs, affecting the luminous efficacy. These losses are determined by the upper limit of the components themselves, which is the upper limit of the luminous efficacy of the LED street light module. To increase the luminous efficacy of the LED street light module, these materials need to be replaced. However, the effect of simply replacing materials on the luminous efficacy improvement is limited, while the cost increases significantly. Therefore, simply piling up materials has a very limited effect on improving the luminous efficacy of street lights. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the background technology and provide a new type of street light module that can improve luminous efficiency. This street light module uses reflective paper to reflect the light lost by the lamp beads, thereby increasing the luminous efficiency by 3~5Lm / W.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A novel street light module with improved luminous efficiency includes a heat sink, a lamp panel, a lamp cover, and a waterproof line. The heat sink has heat dissipation fins on one side and a lamp panel and lamp cover on the other side, with the lamp panel located between the lamp cover and the heat sink. The waterproof line is installed on the heat sink, passes through it, and connects to the lamp panel to provide power. LED beads are mounted on the lamp panel. Lenses corresponding to each LED bead are machined on the lamp cover. Reflective paper is mounted on the lamp panel, with clearances to avoid the LED beads. The lenses are plano-convex lenses, with their inner walls flush with the lamp cover's inner wall. A focusing groove is machined on the side of the lens closest to the LED bead. A gap is left between the reflective paper and the lamp cover; the reflective paper reflects the light scattered by the LED beads toward the lens.

[0006] The reflective paper is bent and has an arc-shaped groove aligned with the light-gathering groove.

[0007] The novel street light module with improved luminous efficiency provided by this utility model has the following beneficial effects:

[0008] (1) By setting reflective paper, the light reflected by the lens and the light diffused by the LED beads can be gathered together and reflected out again from the lens, which can increase the light efficiency of the street light module by 3~5Lm / W.

[0009] (2) By processing arc-shaped grooves on reflective paper, the light-gathering effect can be further enhanced, thereby reducing the loss of light passing through the lens. Attached Figure Description

[0017] Example 1

[0018] like Figures 1-4As shown, the novel street light module with improved luminous efficiency provided in this embodiment includes a heat sink 1, a lamp panel 2, a lampshade 3, and a waterproof line 4. One side of the heat sink 1 is machined with heat dissipation fins 11, and the other side is fitted with the lamp panel 2 and the lampshade 3. The lamp panel 2 is located between the lampshade 3 and the heat sink 1. A sealing strip is also installed between the lampshade 3 and the heat sink 1 to ensure the lamp panel's airtightness. The waterproof line 4 is installed on the heat sink 1, passes through the heat sink 1, and connects to the lamp panel 2 to provide power to the lamp panel 2. LEDs are mounted on the lamp panel 2. The lamp bead 21 has a lens 31 corresponding to each LED bead 21 on the lamp cover 3. The lamp board 2 is equipped with reflective paper 5, which has a clearance 52 that avoids the LED bead 21. The lens 31 is a plano-convex lens 31, and the inner wall of the lens 31 is flush with the inner wall of the lamp cover 3. A focusing groove 32 is processed on the side of the lens 31 near the LED bead 21. A gap is left between the reflective paper 5 and the lamp cover 3. The reflective paper 5 is used to reflect the light scattered by the LED bead 21 toward the lens 31.

[0019] Example 2

[0020] This embodiment is basically the same as Embodiment 1, except that an arc-shaped groove 51 aligned with the light-gathering groove 32 is formed by bending and processing the reflective paper 5. Figure 5 As shown, the arc groove 51 enhances the light-gathering effect and effectively reduces the loss of light passing through the lens 31.

[0021] The principle of this utility model is:

[0022] When the LED beads 21 are powered on, most of this light shines into the focusing groove 32 and passes through the lens 31 to illuminate the streetlight. However, the light transmittance of the lens 31 causes some light to be reflected, and the LED beads 21 also scatter some light. Under the influence of the reflective paper 5, most of this reflected and scattered light re-enters the focusing groove 32, thereby enhancing the luminous efficacy of the streetlight module by 3-5 lm / W. If an arc-shaped groove 51 is machined into the position of the reflective paper 5 corresponding to the focusing groove 32, the focusing effect can be further enhanced, thus reducing light loss.

[0023] This patent applies to various LED street light modules.

[0024] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present invention should be covered within the scope of protection of the present invention.
