Description

LED street lamp lamp holder

Technical field

The utility model belongs to a kind of lighting apparatus, particularly relates to the lamp holder that a kind of LED uses.

Background technology

Road lighting is the important component part of city illumination, and traditional street lamp often adopts high-pressure mercury lamp 360 degree of luminescences, and the shortcoming that light loss is large causes the huge waste of the energy.Current, global environment is going from bad to worse, and each state is all at development clean energy resource.And along with the rapid growth of national economy, China's energy supply and demand contradiction is outstanding day by day, supply of electric power comes into existence the situation of critical shortage, and energy-conservation is institute's urgent problem.Therefore, development of new is efficient, energy-conservation, the life-span is long, colour rendering index is high, the LED street lamp of environmental protection is of great significance the energy-conservation tool of city illumination.

Road lighting and people's productive life closely related, along with the quickening of Urbanization in China, LED street lamp with directional lighting, the advantage such as power consumption is low, drive characteristic good, fast response time, shock resistance are high, long service life, environmental protection enter into gradually people the visual field, become the energy-conserving light source of new generation most in the world with alternative conventional light source advantage, therefore, LED street lamp will become the optimal selection of roadway illumination and energy saving transformation.

It is U-shaped housing that current LED street lamp lamp holder is a cross section be made up of base plate and two side plates, and back side of shell arranges fin etc., enclosure interior mounted LED lamp plate, then at housing two end face installation end panels, transparent panel is installed in the front of shell nozzle.

The shortcoming of current LED street lamp lamp holder is: base plate is a surface plate, and two side plates are vertical with base plate, and the angle major part of such LED lamplight is irradiated downwards, open not, can not more effectively road pavement illumination.

Utility model content

The utility model provides a kind of LED street lamp lamp holder, its objective is the shortcoming solving prior art and exist, makes the range of exposures of LED street lamp wider.

The utility model solves the technical scheme that its technical problem adopts:

LED street lamp lamp holder, it is a strip section bar, it is characterized in that: it has bottom surface, a center, bottom surface, side is extended respectively to oblique upper in the both sides of bottom surface, center, bottom surface, side and bottom surface, center angle are 10 °-30 °, bottom surface, side end oliquely downward extends side, and the angle of side and bottom surface, center is 30 °-60 °; The upper surface of bottom surface, described center and bottom surface, side is provided with several pieces fin upwards extended; Upper surface or the lower surface of bottom surface, described center, bottom surface, side, side are provided with installation draw-in groove.

Usefulness of the present utility model is:

The utility model is by changing the cross sectional shape of LED street lamp lamp holder, make the lower surface of LED street lamp lamp holder towards different sides, the light of such installation LED on the lower surface just can according to different directions, and irradiating angle is greater than the LED of installing in current LED street lamp lamp holder, can more effectively road pavement illumination.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the utility model cross section structure figure.

Detailed description of the invention

As shown in Figure 1, the utility model be LED street lamp used LED street lamp lamp holder, it is an aluminum alloy strip profiled bar, be with existing LED street lamp lamp holder difference, it has bottom surface, a center 1, bottom surface, side 2 is extended respectively to oblique upper in the both sides of bottom surface, center 1, bottom surface, side 2 is 10 °-30 ° with the angle α of bottom surface, center 1, angle α can set according to the requirement of specific product, the end of bottom surface, two sides 2 oliquely downward extends side 3 respectively, side 3 is 30 °-60 ° with the angle β of bottom surface, center 1, angle β can set according to the requirement of specific product, the upper surface of bottom surface, center 1 and bottom surface, side 2 is provided with several pieces fin 4 be parallel to each other upwards extended, the lower surface of bottom surface, center 1 is provided with and installs draw-in groove 11, the lower surface of bottom surface, side 2 is provided with and installs draw-in groove 21, and upper surface is provided with and installs draw-in groove 22, the end of side 3 is provided with and installs draw-in groove 31.

LED lamp panel just utilizes installation draw-in groove to be arranged on the lower surface of bottom surface, side 2 and bottom surface, center 1, two end faces of lamp holder utilize installs draw-in groove installation end panel, utilize the installation draw-in groove 31 of side 3 end that transparent panel is installed, such formation LED street lamp, like this, the irradiating angle of LED lamplight is exactly the angle theta of two sides 3, obviously large than the irradiating angle of the LED lamp holder of prior art.

Claims

1.LED road lamp cap, it is a strip section bar, it is characterized in that: it has bottom surface, a center, bottom surface, side is extended respectively to oblique upper in the both sides of bottom surface, center, bottom surface, side and bottom surface, center angle are 10 °-30 °, bottom surface, side end oliquely downward extends side, and the angle of side and bottom surface, center is 30 °-60 °; The upper surface of bottom surface, described center and bottom surface, side is provided with several pieces fin upwards extended; Upper surface or the lower surface of bottom surface, described center, bottom surface, side, side are provided with installation draw-in groove.
