Problems solved by technology
At present, there are few special roadway lights specially designed for roadways on the market. Because of the narrow and long special environment of the roadway, the traditional circular light distribution cannot meet the requirements, and there are optical blind spots in the irradiation range.
Even roadway lights with long and narrow light distribution cannot meet market demand due to power factor control
For example: a 20W roadway light for a three-meter-high roadway can meet the illumination requirements, but when it reaches a 5-meter-high roadway, this roadway light is no longer applicable, but it is a waste to use a 20W power lamp for a 2-meter-high roadway
[0003] Traditional roadway lights generally have fixed power, high power consumption, high calorific value, and short lifespan, requiring frequent replacement of light-emitting elements

Embodiment approach
[0029] Further, see also Figure 2 to Figure 5 , as a specific embodiment of the roadway lamp with optional power provided by the present invention, the lamp housing 1 includes an upper housing 11 and a lower housing 12, and a plurality of The heat dissipation ribs 111 , the LED heat dissipation fixing plate 21 are closely connected to the upper casing 11 . In this embodiment, a plurality of heat dissipation ribs 111 are provided on the upper casing, which can increase the heat dissipation area of the lamp casing. At the same time, the LED heat dissipation fixing plate 21 is closely connected to the upper casing 11. The heat generated can be efficiently conducted to the lamp housing through the LED heat dissipation fixing plate 21, and the heat dissipation area of the housing increases, and the heat dissipation rate increases accordingly, so that the heat can be effectively dissipated into the air without causing the The temperature inside the lamp shell is too high, ther...

The invention applies to the technical field of lighting and provides a power-optional tunnel lamp, comprising a lamp housing, a light source part arranged inside the lamp housing, and a light source driving part for driving the light source part to operate. The light source part is an SMD LED light source, comprising an LED heat dissipation fixed plate and at least one LED lamp bead. The LED heat dissipation fixed plate is provided with a plurality of LED lamp bead plug seats and any number of LED beads is optionally plugged into the LED plug seats to realize light source setting according to power requirements. The light source driving part is provided with an optional multi-power output selection stall switch. Lens components for light distribution are arranged above the LED lamp beads. The lens components are in connection with the LED heat dissipation fixed plate and fit with the LED lamp bead plug seats. The power-optional tunnel lamp employs the SMD LED light source, and the number of the LED lamp beads in the lamp can be properly selected according to the lighting requirement in the tunnel which the lamp is applied to, therefore a change of power is realized to fulfill different needs.
Description
technical field [0001] The invention belongs to the technical field of lighting, and more specifically relates to a roadway lamp with optional power. Background technique [0002] Roadway lights are generally suitable for fixed lighting in coal mine tunnels and caverns, and can also be used for on-site lighting of belt conveyors. At present, there are few special roadway lights specially designed for roadways on the market. Because of the narrow and long special environment of the roadway, the traditional circular light distribution cannot meet the requirements, and there are optical blind spots in the irradiation range. Even roadway lights with long and narrow light distribution cannot meet market demand due to power factor control. For example: a 20W roadway light for a three-meter-high roadway can meet the illumination requirements, but when it reaches a 5-meter-high roadway, this roadway light is no longer applicable, but it is a waste to use a 20W power lamp for a 2-me...
