Abstract

The utility model discloses a street lamp, including the reflector, high strength discharge lamp etc, the reflector internal surface falls into the front end along the reflector longitudinal axis, the middle -end, the rear end, the front end is equipped with protruding divided corrugate triangle curved surface, the middle -end is equipped with protruding divided corrugate circular arc camber, the rear end is equipped with the triangle curved surface of lamp stand screw hole, and still be equipped with the arch of following the lamp stand screw hole and outwards dispersing on the triangle curved surface of rear end, high strength discharge lamp passes through lamp stand screw hole seal installation in the reflector, be equipped with the cell -shell in the high strength discharge lamp, cell -shell length is 0.5cm~3cm, the cell -shell central point is just in time arranged in on the optical center point of reflector, shine behind the reflector grading when the light source and describe for similar rectangle in subaerial illumination area territory. The utility model discloses can equitable grading, with illumination control in certain road surface regional context, guarantee that illumination is bright, even in regional, it is extravagant to reduce regional outer light energy, but simultaneously and the direct projection of effective control light and dazzling solely.

Description

A kind of street lamp

Technical field

The utility model is related to a kind of street lamp.

Background technology

Urban transportation is intricate, and this requires the illumination of urban road more rationally effectively, just can guarantee that the peace of traffic Row for the national games, while also requiring that the reduction cost when lighting requirement is met as far as possible, accomplishes energy-efficient effect, uses in street lamp In, it is to increase source efficiency, light efficiency is given full play to, it is general that light fixture light efficiency is improved using reflector made by aluminium panels punching press Method, but because reflector internal structure is single, easy formation hot spot and glare, along with lacking precision optical design Reflector, easily causes and penetrates light, region transitions illumination etc., and road lamp efficiency can not only lost, and can cause road illumination Uneven, large power road lamp equipment wastes electric energy, also causes a hidden trouble to night traffic safety illumination.

Utility model content

For deficiency of the prior art, the utility model provides a kind of street lamp, and the reasonable luminous intensity distribution of energy exists illumination control In certain road surface regional extent, it is ensured that illumination is bright, uniform in region, reduce luminous energy outside region and waste, while and can be effective The direct projection of control light and glare.

The utility model is achieved through the following technical solutions：A kind of street lamp, including reflector, high-intensity gas discharge lamp with And the shell that cooperates and lampshade, the inner surface of the reflector is divided into front end, middle-end, rear end along the longitudinal axis of reflector, The front end is provided with the corrugated circular arc camber that the corrugated triangular surface of raised separation, middle-end are provided with raised separation, and rear end sets There is the triangular surface of lamp socket screwed hole, and the projection outwards dissipated along lamp socket screwed hole, institute are additionally provided with the triangular surface of rear end State high-intensity gas discharge lamp to be sealingly mounted in reflector by lamp socket screwed hole, be provided with the high-intensity gas discharge lamp Cell-shell, the cell-shell length is 0.5cm～3cm, and the central point of cell-shell is just placed in the optic center point of reflector, works as light source The illumination region irradiated after reflected device luminous intensity distribution on the ground is similar rectangular-shaped.

Preferably, the reflector is anodic oxidation aluminium material or glass material.

Preferably, be provided with the lampshade making the expanded glass plate of light transmission.

Preferably, the cross section of the shell is oval ring, shell is provided with steel fastener, by lampshade, reflector It is fastened on shell by steel fastener.

Compared with prior art, the utility model has the advantages that：By improving original reflector inner surface Semiellipse cambered surface is designed to for reflector inner surface to be arranged to three regions, and front end can suppress light with the triangular surface of rear end And with it is similar it is rectangular-shaped be radiated in the rational regional extent in road surface, prevent light to be irradiated to outside region, cause luminous energy to waste；Together When by selecting Pressurized gas discharge bulb shell length between 0.5cm～3cm, by by the light of cell-shell central point and reflector Learn central point to overlap, optimal light distribution effect can be reached, efficient utilization light source, reflection efficiency height, luminous intensity distribution are uniform;By on lampshade Being provided with makes the expanded glass plate of light transmission, and light can be made dispersed, further control direct projection and glare.

Description of the drawings

Fig. 1 is the structural representation of the utility model street lamp.

Fig. 2 is the structural representation of reflector in street lamp.

Specific embodiment

Below in conjunction with the accompanying drawings with specific embodiment, the utility model is described further.

As shown in Figure 1 and Figure 2, a kind of street lamp, including reflector 1, the high-intensity gas discharge lamp 2 being arranged in reflector And the shell 3 that cooperates and lampshade 4, the wherein inner surface of reflector 1 is divided into front end 1b, middle-end along the longitudinal axis of reflector 1a, rear end 1c, front end 1b is provided with the corrugated circular arc song that the corrugated triangular surface of raised separation, middle-end 1a are provided with raised separation Face, rear end be provided with the triangular surface of lamp socket screwed hole 1d, and rear end 1c triangular surfaces be additionally provided with it is outside along lamp socket screwed hole 1d The projection of diverging, high-intensity gas discharge lamp 2 is sealingly mounted in reflector 1 by lamp socket screwed hole 1d, and high-intensity-gas are put Cell-shell 2a is provided with electric light 2, the length of cell-shell 2a is 0.5cm～3cm, and the central point of cell-shell 2a is just placed in the light of reflector 1 Learn central point on, by such design can overcome original semiellipse arc-shaped curved surface due to outside region illumination cause luminous energy to waste Shortcoming, light can be suppressed and with it is similar it is rectangular-shaped be radiated on road surface, and be to allow by limiting the length of cell-shell Light distribution effect reaches most preferably；Further, the material of reflector 1 is anodic oxidation aluminium material or glass material；Further, lamp The expanded glass plate for making light transmission is provided with cover 4, light can be made dispersed, control direct projection and glare；The horizontal stroke of supporting shell 3 Section is oval ring, and shell 3 is provided with steel fastener, and lampshade 4, reflector 1 are fastened on shell 3 by steel fastener.

Protection domain of the present utility model includes but is not limited to embodiment of above, and protection domain of the present utility model is weighing Sharp claim is defined, and any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement each fall within Protection domain of the present utility model.
