Referring to fig. 1 and 2, a first embodiment of the utility model provides a lamp 1, where the lamp 1 includes a substrate 10, a lamp bead 20 and a lamp cover 30, a surface of the substrate 10 facing the lamp cover 30 is defined as an inner surface 11 of the substrate, the inner surface 11 of the substrate is a light-reflecting surface, the lamp bead 20 is disposed on the inner surface 11 of the substrate, and the lamp cover 30 is fastened on the inner surface 11 of the substrate and forms a lamp cavity together with the substrate 10. The lamp housing 30 defines a light-emitting portion 301 and light-reflecting portions 302 located at two sides of the light-emitting portion 301, and the light-reflecting portions 302 extend to a connection portion between the substrate 10 and the lamp housing 30. Part of the light emitted by the lamp beads 20 directly exits from the light-emitting portion 301, and the other part of the light exits from the light-emitting portion 301 after passing through the light-reflecting portion 302 and/or after being reflected by the substrate 10. Through the design that the light reflecting part 302 is arranged at the position, close to the connection part with the substrate 10, of the lampshade 30, light emitted to the edge is reflected back to the lamp cavity through the light reflecting part 302 and then directly emitted from the light emitting part 301, and/or is reflected through the substrate 10 and then emitted from the light emitting part 301, the light irradiated to the edge cannot be emitted at the edge to form glare, the edge position UGR is reduced, the softness of the light of the lamp is increased, the glare is reduced, and the problems that the existing lamp UGR does not meet the requirements and the eyesight is damaged are solved.

Referring to fig. 3, as an example, most of light emitted by the lamp bead 20 is emitted from the middle portion of the lamp shade 30, and a small portion of light emitted from the edge of the lamp shade 30 close to the substrate 10 is reflected by the light reflecting portion 302, and then reflected by the substrate 10 to the light emitting portion 301 again, and a portion of light is reflected by the light reflecting portion 302 and then directly emitted from the light emitting portion 301. The light rays at the edge can cause the UGR of the lamp to increase, and the method of arranging the light reflecting part 302 can achieve the effect of reducing the UGR by realizing low cost without changing the original structure of the lamp.

For ease of understanding, the side of the substrate 10 facing away from the lamp housing 30 is defined as the substrate outer surface 12.

It will be appreciated that the substrate 10 may be made entirely of a light reflective material, such that both the substrate inner surface 11 and the substrate outer surface 12 are light reflective, or that only the substrate inner surface 11 is a light reflective surface. Specifically, the reflective surface may be implemented by disposing a reflective film layer on the inner surface.

Optionally, the substrate 10 may be an aluminum substrate, and the aluminum plate has a reflection performance and has the advantages of light weight, good waterproof and antifouling performance, and the like; alternatively, the substrate 10 may be another plate having a reflective film such as a silver-plated film or an aluminum-plated film, which can satisfy the reflective performance requirement and enhance the deformation resistance. It is understood that the reflective film is formed on a surface of the substrate 10 facing the lamp housing 30, i.e., the substrate inner surface 11.

Similarly, the light-reflecting portion 302 may be provided with a light-reflecting layer on a side facing the substrate 10 to achieve a light-reflecting effect, for example, reflective paper is used to achieve the light-reflecting effect, the reflective paper is simple to use and low in price, and can increase the brightness and lumens of the lamp and reduce glare; or, the reflective layer may be provided with a reflective oil layer on one side facing the substrate 10, and the reflective oil layer may be provided by spraying or brushing, so as to ensure uniform coating, and the reflective oil layer does not change the structure and color of the carrier, and does not generate glare. In addition, the light reflecting portion 302 may be formed by two-color extrusion molding with the light emitting portion 301 by directly using a light reflecting material.

Further, the ratio of the width of the light reflecting portion 302 to the width of the light emergent portion 301 ranges from 1/6 to 1/4. The width ratio is set so that the light emitting of the light emitting part 301 is not affected while the light reflecting effect required by the light reflecting part 302 is satisfied, if the light reflecting part 302 is too large, the light cannot be emitted from the light emitting part 301, the loss caused by too many reflection times in the lamp cavity is caused, and simultaneously, the UGR of the lamp can be increased due to the fact that the light is all emitted from the small light emitting part, and the reverse effect is achieved.

Furthermore, the connecting devices 50 are all located on the same plane, so that the effect of increasing the flatness of the lamp is achieved. Meanwhile, the extending portion 101 of the substrate 10 is configured as an inclined surface inclined with respect to the substrate 10, the inclined surface faces the direction of the lampshade 30, and the inclined surface is configured to enable a part of light reflected to the outside of the lampshade through the light emitting portion 301 to be reflected back to the light emitting direction again, so that the brightness and the light utilization rate of the lamp 1 are increased. It is understood that the inner surface 111 of the extension portion described herein may be a light reflecting surface, such as a light reflecting material or a light reflecting material disposed on the inner surface 111 of the extension portion 101.
