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 base, a casing, a light sensing module, a lighting module, a power source, and an outer cover. The housing is fixed to one side of the base, and the light sensing module is disposed in the housing. The light emitting module is fixed on the other side of the base and electrically connected to the light sensing module. The power source is also fixed on the base and is located on the same side of the housing, and is electrically connected to the light sensing module and the light emitting module. The outer cover is fixed to the same side of the base and the casing, and covers the casing and the power source.

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 casing to prevent the light-sensing module from being damaged by the influence of the environment. If maintenance is required, the cover can be opened to replace or repair the light sensor module or power supply. It is also possible to directly remove the light module for replacement or maintenance without opening the cover, thereby improving the convenience of subsequent maintenance.

The housing can be a light transmissive housing such that the light sensing module disposed in the housing can receive external light source changes. The external light source can also be penetrated into the casing by opening a hole in the casing.

The light emitting module of the above lamp may include a light source module and a lens module. The light source module includes a plurality of light-emitting elements and a circuit board, and the plurality of light-emitting elements can be disposed on the circuit board at equal intervals. The board is attached to the base. The plurality of light emitting elements may be Light-emitting Diodes (LEDs). The lens module covers the light source module and is directly locked to the base, and the lens module includes a plurality of lenses, and the plurality of lenses individually correspond to the respective light-emitting elements.

In other embodiments, the base of the lamp is provided with a through hole and covered There is a one-way tarp. The one-way tarpaulin prevents external liquid water from entering between the base and the lens module through the through hole of the base, but the water vapor between the base and the lens module can be dissipated by the through hole. Thereby, in the illuminating process, the water vapor accumulated between the base 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 luminaire may include a waterproof strip disposed between the base and the lens module. The waterproof rubber strip can be used to prevent moisture from entering the light-emitting module from the joint between the base and the lens module, and affecting the light source module disposed on the base and the lens module.

Based on another concept of the present creation, the luminaire can include a bracket that is locked to the base. The bracket is used to fix the luminaire to the support frame.

Based on another concept of the present invention, the light sensing module 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 outer cover of the luminaire may have a perforation, and the perforation is located corresponding to the casing. Then, a lens is used to pass through the through hole, so that external light can be diverged into the outer cover through the lens and directly irradiated onto the casing. The light sensing module disposed in the outer cover and in the housing can accurately receive the brightness of the external environment to control the opening or closing of the light emitting module.

Based on another concept of the present creation, the luminaire may include a lightning strike preventer disposed in the housing. The lightning protection device is used to protect the power line in the lamp and avoid the mine The strike current is too high or too high, causing damage to the luminaire circuit.
