Description

High heat dissipation LED module street lamp head with adjustable irradiation angle

technical field

The invention discloses a structure of a high heat dissipation LED module street lamp lamp cap with adjustable irradiation angle, which belongs to the technical field of semiconductor lighting.

Background technique

At present, the light sources used for street lighting include: incandescent lamps, high-pressure mercury lamps, high-pressure sodium lamps, metal halide lamps, fluorescent lamps, etc. The main disadvantages of these lamps are: ① Not environmentally friendly: heavy metals such as mercury, lead, and arsenic are harmful to the environment ; ② high energy consumption; ③ short life.

Traditional street light sources contain heavy metals and pollute the environment; LED light sources do not contain heavy metals and will not pollute the environment. Because the traditional street light source is spherical, the light divergence is not easy to control, and the light is easy to overflow the designated irradiation area, so light pollution is formed; because the light angle of LED can be set, the light can be controlled, and the light can be fully illuminated to the designated area, so there is no light pollution.

The energy consumption of traditional street light sources is 5-10 times that of LEDs. Especially in the context of my country's current energy shortage, choosing LED light sources as street light sources can fundamentally solve the problem of high energy consumption and high electricity bills of traditional street lights.

In terms of color rendering: traditional street lamps are poor, such as sodium lamps, whose color rendering index can only reach about 30; while LED color rendering index can reach more than 75, which is closer to natural light lighting effects. From the perspective of human visual sensitivity: LED street lamps More suitable for road lighting.

In terms of uniformity: the uniformity of traditional street lamps is low. Although the vertical illuminance can reach the road lighting standard, the edge illuminance is far lower than the vertical illuminance. , the vertical illuminance and edge illuminance both meet road lighting standards.

Traditional street lamps can only reach the level of "brightness", not the level of "quality" of lighting. Because the light source of traditional street lamps is spherical light, the direction of light is uncontrollable, forming a circular aperture (spot) on the road surface, resulting in partial shadows, poor lighting effect, and visual impact on pedestrians and vehicle drivers, so it is easy to generate traffic. ACCIDENT. In addition to improving the lighting effect in terms of color rendering and uniformity, LED street lights also form a complete light belt on the lighting road because of the controllability of the LED light-emitting direction (the light-emitting angle can be locked) through the secondary light distribution design. , no shadows, no visual impact on pedestrians and vehicle drivers, good road lighting effects, greatly improving road safety.

At present, there are many kinds of LED street lamps at home and abroad, and the performance is uneven. Due to the constraints of LED lamps in terms of quality and heat dissipation requirements, it is difficult to meet the lighting needs of ultra-high-power LED street lamps.
