Definitions
- the present invention relates to a light emitting diode (LED) lamp, and more particularly to a lamp base structure of an LED street lamp.
- LED light emitting diode
- Street lamps are used to guide passengers and indicate vehicles. There has been a determined distance between two street lamps to avoid setting too many street lamps for saving costs. However, there often are unlit areas between street lamps on roads. In a worst-case, the safety of passengers is at risk.
- FIG. 1A is a schematic view for current street lighting. It includes a lamp pole 1, a lamp arm 2 and a lamp set 3.
- the included angle between the lamp arm 2 and the lamp pole 1 is an unvarying quantity of X, it is usually about 101 degree to 105 degree. Under this included angle, a projected area on the ground of the lamp set 3 is A.
- FIG. 1B the included angle between the lamp arm 2 and the lamp pole 1 is changed to Y. Because the direction of the lamp set 3 projecting to the ground is changed, the projected area on the ground by the lamp set 3 is enlarged from A to B. Accordingly, it can solve the problem of unlit areas between street lamps.
- one object of the present invention is to provide a lamp base improvement of a street lamp, which can solve the problem of unlit areas between street lamps by setting a longitudinally slanted bottom of a bracket of a lamp base.
- the invention can change the direction of the lamp set projecting to the ground without rebuilding lamp poles and lamp arms.
- the present invention provides a lamp base improvement of a street lamp. It mainly includes a lamp base, which forms a plurality of brackets inside.
- the brackets are set to have longitudinally slanted bottoms with respect to a transparent mask.
- lighting modules are separately disposed on a bottom of the brackets.
- the transparent mask is assembled to the lamp base to cover the plurality of lighting modules.
- the present invention is to provide a lamp base improvement of a street lamp. It includes a lamp base 10, a plurality of lighting modules 20 and a transparent mask 30.
- the lamp base 10 is made of die casting aluminum.
- a plurality of heat dissipating fins 11 and brackets 12 are disposed on the outside and inside of the lamp base 10, respectively.
- the brackets 12 are array arranged and bowl shaped, or a cross section of the bracket 12 is trapezoid shaped.
- the brackets 12 are arranged into a ladder-shape in a longitudinal direction and having at least three longitudinal lines (refer to FIG. 3 and FIG. 5 ). Two outside lines of brackets 12 are slanted inward for light gathering.
- the lighting module 20 includes a fixing base 21, a substrate 22, a lighting unit 23, a refection cover 24 and a lens 25.
- the fixing base 21 is fixed on the bottom 121 of the bracket 12, and the substrate 22 is disposed on the fixing base 21.
- the lighting unit 23 including a plurality of LEDs is connected to the substrate 22.
- the refection cover 24 which has an accommodating space 241 therein for receiving the lighting unit 23.
- One end of the refection cover 24 is fixed on the fixing base 21, and the other end is covered with the lens 25.
- the lens 25 can be a Fresnel Lens for enhancing light convergence of the lighting module 20.
- the corresponsive arrangement between the lens 25 and the refection cover 24 can allow adjusting the angle projecting to the ground for enlarging the effective lit area.
- the fixing base 21 is disposed on the bottom of the bracket 12, the lighting modules 20 connecting to the fixing base 21 are also disposed along the bottom of the bracket 12 inside the lamp base 10. Even more, the transparent mask 30 being a flat plate is disposed on the lamp base 10 to cover sealedly those lighting modules 20. The transparent mask 30 can make illumination components sealed in the lamp base 10 to prevent from humidity and ultimately being damaged. Besides, the bottom 121 of the bracket 12 inside the lamp base 10 is longitudinally slanted with respect to the transparent mask 30.
- FIG. 6 is a schematic view showing a lamp base improvement of the present invention improvement, which is applied to a street lamp.
- the invention lamp base 10 is assembled on the lamp arm 2 of a lamp pole 1.
- the included angle between the lamp arm 2 and the lamp pole 1 of a street lamp is X.
- the projecting area from the lamp base 10 on the lamp arm 2 towards the ground is B.
- the lamp base 10 of the invention can change projecting direction for adjusting projecting area of the street lamps.
- the lamp base 10 improvement of a street lamp is on the bracket 12, which is longitudinally to set the bottom 121 to be slanted.
- the bracket 12 By setting a plurality of lighting modules 20 on the bottom 121 of the bracket 12, it can provide an LED street lamp which can change the projecting direction.
