A stage light free from damage of sunlight includes a light body and a control assembly, and a light avoiding system. When the light body is in a power-on state, the control assembly controls the light avoiding system not to work; and when the light body is in a power-off state, the control assembly controls the light avoiding system to implement a light avoiding action. According to the present invention, smart light avoiding according to a sunlight status can be achieved by means of a light avoiding system. The light avoiding system has advantages of a high automatic recognition level, a flexible access system, and being cost-effective and easy to implement.

In one embodiment, a light assembly includes a base substrate; a light-emitting device supported by the base substrate; a cover permeable to volatile compounds, completely surrounding the light-emitting device and being transparent to a light flux emitted, during use, by the light-emitting device; a gas sensor configured to sense the volatile compounds, the gas sensor being arranged within the cover. The light assembly includes a pump having an inlet operatively coupled to the cover, and operable to generate a pressure depression within the cover. The light assembly includes a light sensor operatively coupled to the light-emitting device, the light sensor being configured to sense a light intensity value of at least one light component of the light flux. The light assembly includes a processor operatively coupled to the gas sensor, the light sensor, and the pump; a non-volatile memory storing a program to be executed in the processor.

The present invention discloses a side-emitting LED panel lamp, where the side-emitting LED panel lamp includes a frame, a light-emitting element, a driving power supply, a backboard, a pressing bar, a light guide plate, and a diffusion plate; the light-emitting element, the driving power supply, and the backboard are disposed on a lower surface of the frame; the pressing bar is disposed around the backboard and covers the driving power supply; the driving power supply is electrically connected to the light-emitting element; the light guide plate is disposed on a lower surface of the backboard; the light guide plate is flush with the light-emitting element; and the diffusion plate is disposed on a lower surface of the light guide plate. In the present invention, all the components are integrally assembled. When used, the side-emitting LED panel lamp can be directly connected to a mains power supply, so as to avoid lamp damage caused because the light-emitting element does not match the driving power supply due to secondary adjustment, therefore facilitating a direct operation of a user.

An articulated positioning assembly includes a first support channel and a second support channel coupled together using a joint assembly having a plurality of degrees of freedom of movement. A magnetic coupling assembly is coupled to the first support channel and is configured to couple the first support channel to a support surface of a plurality of support surfaces. A light fixture comprising a plurality of individual point light sources is coupled to the second support channel and configured to generate a light field over a work area.

The present invention relates to an eye-friendly illumination spotlight used for cleaning the baby's excreta at night, comprising an open box body with an opening at bottom, the bottom opening of the open box body being mounted with a detachable bottom cover, wherein the open box body comprises a front side of the box body detachably arranged on the open box body, the inner wall of the front side of the box body is fixedly provided with a first luminous assembly and a second luminous assembly arranged symmetrically, the lighting path of the first luminous assembly intersects the lighting path of the second luminous assembly to form an X-shaped lighting path. The present invention has the following benefits: the lighting is good for shining the baby's buttocks and is dispersed and reduced rapidly after clustering. When using, it will not cause a direct shining the baby's eyes, and will not affect the baby's sleeping, more will not injure the baby's vision. It can meet the requirements of the lighting for parents changing the nappy at night and cleaning the baby's extract, and is convenient to use.
