Description

TECHNICAL FIELD

[0001] The present application relates to the field of lighting, in particular to a lighting unit and a lighting lamp. BACKGROUND

[0002] Lamp is the general term for lighting tools, including ceiling lamps, table lamps, wall lamps, floor lamps, etc. It refers to a device that can transmit light, distribute and change the light distribution of a light source. It is widely used in public places such as stores, offices, factories and parking lots. Most of the existing lamps can only rely on powered light-emitting units to achieve the purpose of lighting. Common light-emitting units generally include incandescent lamps and LED lamps. The principle of incandescent lamp is that when electric current passes through the filament (tungsten wire, melting point above 3000°C), heat is generated. The spiral-shaped filament continuously collects heat, so that the temperature of the filament reaches above 2000°C. When the filament is in a white-hot state, it emits light like a red-hot iron. The higher the temperature of the filament, the brighter the light emitted. From the perspective of energy conversion, a large amount of electrical energy is converted into heat energy when the electric lamp emits light, and only a small part can be converted into useful light energy. LED lamp is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. Similarly, LED lamp also converts part of the electrical energy into heat energy, generating heat. In summary, both incandescent lamps and LED lamps generate heat energy, resulting in energy waste and indoor temperature rise. In addition, the emitted light is in a divergent state, and the indoor lighting light is not uniform. SUMMARY

[0003] The purpose of the present application is to design a lighting unit and a lighting lamp to solve the above problems.

[0004] The present application achieves the above-mentioned purpose by the following technical solutions:

[0005] The lighting unit comprises:

[0006] A housing; a first mounting groove is provided on a first side of the housing;

[0007] A first light-emitting module; the first light-emitting module is installed in the first mounting groove, and the lighting direction of the first light-emitting module is towards the direction of gravity;

[0008] A first reflective surface for reflecting light; the first reflective surface is provided on a second side of the housing, the first side and the second side are respectively located on two sides of the housing, and the included angle between the first reflective surface and the horizontal plane is greater than 0° and less than 90°.

[0009] The lighting lamp comprises the above-mentioned lighting unit.

[0010] The beneficial effect of the present application is that the first reflecting surface is arranged on the second side of the shell, after the lighting unit is installed, when the natural light from the outside world is transmitted, the first reflecting surface can reflect the indoor environment, effectively avoiding the case that the natural light is blocked by the lighting unit and cannot illuminate the indoor environment, so that the first light emitting module does not need to be turned on to maintain the bright indoor environment, and the additional heat is not generated without power light, the temperature of the indoor space is relieved, and the purpose of energy saving is achieved; at night, the first light emitting module can illuminate the indoor environment, greatly reducing the daily use time of the first light emitting module, and prolonging the service life of the first light emitting module.
