Abstract

The utility model discloses a dual light source street lamp, comprising a lampshade and a sodium lamp installed in the lampshade and parallel to the top axis of the lampshade, wherein a circuit board is fixed between the inner top of the lampshade and the sodium lamp; reflectors are fixed at the edges of the circuit board and the lampshade; the circuit board corresponding to the sodium lamp is also welded with an LED light; and the back surface of the circuit board installed with the LED light is fixed with a radiator. The utility model uses the reflectors of the lamp for light reflection, mixes the white light of the LED and the red light of the sodium lamp, improves the whole color temperature, color rendering property and illumination of the lamp, and reduces the glare and ghosting of the LED light source, thus leading the light rays to be close to the natural color and to have high brightness and low energy consumption, and prolonging the service life of the street lamp by adding the radiator.

Description

A kind of double-light source street

Technical field

The utility model belongs to technical field of lamps, is meant a kind of double-light source street especially.

Background technology

The LED energy-saving lighting lamp is the product of new science and technology owing to compare with the fluorescent lamp with existing incandescent lamp, have energy-conservation, light efficiency is high, radiationless and advantage that the life-span is long, the LED electricity-saving lamp is applied to various places widely.

Along with social economy's high speed development continuously, energy contradiction can not be put in face of the people with avoiding.Seem especially outstanding as huge lighting energy contradictions of public place power consumption such as urban and suburban roads, square, harbour, school, residential blocks.Therefore utilize efficient, energy-conservation, long-life LED to become the problem of whole world research as lighting source.Because the not enough price of the relatively poor brightness of light efficiency of LED is too high, so become the solar energy lamp preferred light source as every watt of low-pressure sodium lamp near the high light efficiency of 200lm.But the luminous color of low-pressure sodium lamp is seriously red partially, and volume is long, and concerning the client of its custom use warm colour light source, majority is to hope lamp heave a sigh.

It is also not overripened in technology and market that present LED replaces high-pressure mercury lamp as street lamp.Be mainly reflected in following some: the luminous efficiency of 1.LED can't be compared with high-pressure mercury lamp; 2.LED irradiation too concentrated, the uniformity of its irradiation is poor; 3.LED street lamp to light light decay for a long time serious, the life-span is not long; 4.LED luminous quantity instability (short-term light decay) can be in time, seasonal variations; 5.LED the street lamp dead weight is overweight, is unfavorable for installing, and is windproof; 6.LED the street lamp cost is too high, difficult popularizing.

Therefore, how to allow difficult problem pendulum that two kinds of light sources have complementary advantages we in face of.

The utility model content

In order to overcome bright not enough, the high deficiency of power consumption of existing street lamp, the utility model provides a kind of energy consumption little, bright high, and light is near self-colored double-light source street.

The technical scheme that its technical problem that solves the utility model adopts is: this double-light source street comprises lampshade, be contained in the lampshade and with the sodium vapor lamp of the parallel installation of lampshade top axis, between lampshade inner top and sodium vapor lamp, be fixed with circuit board, circuit board and lampshade edge are fixed with reflector, on the circuit board of described relative sodium vapor lamp one side, also be welded with the LED lamp, on the circuit board that the LED lamp back side is housed, be fixed with radiator.

Above-mentioned LED lamp regular distribution on circuit board makes the light intensity of LED lamp be divergent shape; LED lamp regular distribution on circuit board is preferably and makes LED light be bat shape by force.

Described LED lamp be small-power or high-power any one; Sodium vapor lamp can replace with golden lamp or electrodeless lamp, all can require to select for use according to reality.

Effective effect of the present utility model is: utilize the reflector of light fixture reflective, the ruddiness of the white light of LED and sodium vapor lamp mixed rub together, colour temperature, colour rendering, the illumination of light fixture integral body have been improved, reduce the dazzle of led light source and the generation of ghost image simultaneously, make light near Natural color, brightness height, energy consumption are little, have added radiator simultaneously, have prolonged the life-span of street lamp.

Description of drawings

Fig. 1 is the utility model double-light source street structural representation;

The schematic diagram that Fig. 2 distributes on circuit board for the utility model LED lamp.

The specific embodiment

For the ease of those skilled in the art's understanding, the utility model is further described below in conjunction with embodiment and accompanying drawing:

In Fig. 1, this double-light source street comprises lampshade 1, be contained in the lampshade 1 and with the sodium vapor lamp 3 of the parallel installation of lampshade 1 top axis, between lampshade 1 inner top and sodium vapor lamp 3, be fixed with circuit board 4, circuit board 4 and lampshade 1 edge are fixed with reflector 2, on the circuit board 4 of described relative sodium vapor lamp 3 one sides, also be welded with LED lamp 5, on the circuit board 4 that LED lamp 5 back sides are housed, be fixed with radiator.

In Fig. 2, LED lamp 5 regular distribution on circuit board makes the light intensity of LED lamp 5 be divergent shape; LED lamp 5 regular distribution on circuit board 4 is preferably and makes LED lamp 5 light intensity be bat shape.

Described LED lamp 5 be small-power or high-power any one; Sodium vapor lamp 3 can replace with golden lamp or electrodeless lamp, all can require to select for use according to reality.

When sodium vapor lamp 3 is lighted, send serious red partially color light, it is dim to seem when illuminating the road surface; And LED lamp 5 sends the white light of warm colour when lighting, and it is bright to seem when illuminating the road surface, and when sodium vapor lamp 3 and LED lamp 5 lighted simultaneously, the effect by reflector rubbed up the white light of red partially color light and warm colour and forms the high warm light of a kind of light intensity together; When reaching equal brightness, can reduce the power of sodium vapor lamp 3; By LED lamp 5 regular distribution on circuit board, be bat shape as LED lamp 5 light intensity, again in conjunction with the effect of reflector, make the illuminated area maximization of double-light source street; Utilize radiator, the heat that sodium vapor lamp 3 and LED lamp 5 produced in time spreads out of, thereby has prolonged the life-span of street lamp.

The foregoing description is a preferred implementation of the present utility model, and in addition, the utility model can also other modes be implemented.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement also can fall within the protection domain of the present utility model.
