Lamp

This creation is about a luminaire, especially a luminaire that can be used as a street light, a security light, a street light, or a garden light.

In recent years, due to the development of light-emitting diodes (LEDs) and based on environmental protection and energy saving considerations, most lighting devices and lamps have gradually begun to use LED lamps instead of traditional bulbs or mercury tubes.

In Japan, in recent years, it has begun to promote the installation of auxiliary lighting fixtures called lights in parks and other places. The anti-compliance lamp used in outdoor lighting is mainly used to provide sufficient illumination of the road surface within a certain range, so that the clothing, behavior, or posture of the pedestrian in this range can be clearly presented to achieve the effect of deterring crime. .

Since the security lights are mostly installed in outdoor places such as parks or courtyards, the housing needs to have a certain waterproof function to avoid damage to the lamps after being blown by the wind, sun, or rain. Therefore, the shell design is mostly tightly locked, but this method will cause inconvenience in subsequent maintenance. In addition, because it is necessary to provide sufficient illumination for the road surface when the ambient light source is insufficient, it is necessary to be able to turn on the illumination function when it is detected that the ambient light source is below a certain brightness.

A lamp includes: a casing, a partition, a light sensing module, at least one fixing portion, an upper cover, a lighting module, and a power source. The housing has an opening, and the partition is fixed in the housing to space the housing out of an accommodating space. And having a through hole in the housing, so that the accommodating space communicates with the outer boundary of the housing via the through hole.

The light sensing module is disposed in the accommodating space, and at least one fixing portion is protruded from the inner wall surface of the housing. At least one fixing portion can be used to fix the light sensing module in the accommodating space. Then, the upper cover is fixed to the partition and covers the accommodating space.

The light emitting module is fixed on the housing and covers the opening of the housing and is electrically connected to the light sensing module. The power source is also disposed in the housing and electrically connected to the light sensing module and the light emitting module.

Through the above structure, when the light sensing module senses that the external environment is lower than a certain brightness, the light emitting module can be turned on to provide a sufficient illumination source. The light sensing module is disposed in the housing to prevent the light sensing module from being damaged by the influence of the environmental climate. If maintenance is required, the entire lighting module can be removed for replacement or repair. It is also possible to directly replace or maintain the components assembled in the housing when the lighting module is removed.

Based on another concept of the present invention, the luminaire can include a frame disposed at the opening of the housing. The light emitting module can be fixed to the housing via the frame.

Based on another concept of the present invention, the lighting module of the above lamp may include a heat dissipation frame, a light source module, and a lens module.

The lens module covers the light source The module is fixed to the heat dissipation frame, and the lens module comprises a plurality of lenses, each lens correspondingly covering a light-emitting element. In addition, a through hole may be formed in the heat dissipation frame and covered with a one-way tarpaulin. The one-way tarpaulin prevents external liquid water from entering between the heat dissipation frame and the lens module through the through hole, but the water vapor between the heat dissipation frame and the lens module is dissipated by the through hole. Thereby, in the process of illuminating the illuminating module, water vapor accumulated between the heat dissipating frame and the lens module due to temperature changes can be dissipated. The water vapor is prevented from affecting the plurality of light-emitting elements of the light source module, and the light-emitting elements are damaged.

Based on another concept of the present invention, the lighting module of the above lamp may include a transparent plate and an annular outer cover, and the transparent plate covers the lens module. The annular cover covers a portion of the transparent plate and is secured to the heat sink frame to simultaneously secure the transparent plate.

Based on another concept of the present invention, the light emitting module of the above lamp may include a waterproof rubber strip disposed between the heat dissipation frame and the transparent plate. The waterproof strip is used to prevent water vapor from entering the luminaire from the junction of the heat-dissipating frame and the transparent plate, and affecting the light source module disposed between the heat-dissipating frame and the transparent plate.

Based on another concept of the present invention, the luminaire may further include a bracket fixed to the housing for locking the luminaire to the support bracket.

Based on another concept of the present invention, the light sensing module of the above lamp may include a light sensor and a light sensing circuit board. The light sensor is electrically connected to the light sensing circuit board, and the light sensing circuit board is electrically connected to the power source and the light emitting module. The light sensor is used for sensing an external light source, and then controlling the opening or closing of the light emitting module via the light sensing circuit board.

According to another concept of the present invention, the luminaire may include a lens disposed in the through hole to allow external light entering the housing to diverge through the lens into the accommodating space. Make The light sensing module placed in the accommodating space can accurately receive the brightness of the external environment to control the opening or closing of the light emitting module.
