Abstract
The utility model discloses an LED antifog street lamp which comprises a plurality of LED modules (1), a drive power supply (2) and a lamp holder (3). The LED modules (1) are electrically connected with the drive power supply (2) and are arranged on the lamp holder (3), the LED modules (1) are composed of radiators (11), sealing rings (12), LED chips (13), PCBs (14) and light-pervious covers (15), the LED chips (13) comprise red-light LED chips and common white-light LED chips, and the LED chips (13) are indirectly distributed on the PCBs (14) according to a certain proportion. The LED antifog street lamp has the advantages that the percentage of a yellow spectrum area in the spectrum of an LED module light source is high, the wavelength is long, color temperature is low, high permeability is achieved, and the street lamp is made to have strong light permeability and color rendering in rainy and foggy days.
Description
Technical field
The utility model belongs to outdoor road lighting field, particularly the antifog street lamp of a kind of LED.
Background technology
The LED light fixture is due to advantages such as its energy-saving and environmental protection, replace incandescent and electronic energy-saving lamp gradually, become the first-selection of novel green illumination, the white lamp of tradition LED is to produce gold-tinted or green-yellow light by the luminous excitated fluorescent powder of blue chip, make blue light mix according to a certain percentage the generation white light with gold-tinted or green-yellow light, the penetrability of this white-light spectrum, diffusivity and colour rendering are poor, and this light source can only be used in the general lighting occasion, can not be used in special rainy foggy area.Foggy rainy climatic characteristic requires street lamp can possess superpower light penetration and diffusivity, guarantee traffic safety, the penetrability of light in fog precipitation weather is relevant with its wavelength, the penetrability of wavelength longer (being that colour temperature is lower) light is stronger, the colour temperature of sodium vapor lamp is less than 2000K, therefore have and well penetrate effect under foggy weather, but the colour rendering of sodium vapor lamp is very poor.Problem to be solved in the utility model is to provide a kind of LED street lamp that can meet safe driving requirement under fog precipitation weather, and the penetrability that not only can meet light is strong, can also guarantee keeping on top aspect whole light effect and colour rendering.
The utility model content
For solving LED light spectrum penetrability, the poor problem of diffusivity in above-mentioned prior art, the utility model adopts following technical scheme: the antifog street lamp of a kind of LED, comprise a plurality of LED modules, driving power and lamp bracket, described LED module comprises radiator, sealing ring, LED chip, pcb board and diffuser, described LED chip is welded on pcb board, described pcb board is fixed on radiator, described sealing ring is arranged between pcb board and diffuser, and described a plurality of LED modules and driving power are arranged on lamp bracket by electrical connection.
As to improvement of the present utility model, described LED chip comprises red LED chip and common White-light LED chip, and described red LED chip and common White-light LED chip are combined by a certain percentage.。
As to further improvement of the utility model, described red LED chip two one rows be distributed on pcb board indirectly.
The beneficial effects of the utility model are: by certain proportion, by common White-light LED chip red LED chip, both combine composition LED die set light source, in the spectrum of this LED die set light source, the percentage in the general zone of gold-tinted is higher, wavelength is longer, colour temperature is lower, higher penetrability is arranged, the negligible amounts of red LED chip, do not affect the light efficiency of whole street lamp, thereby make street lamp have stronger light penetration and colour rendering under misty rain weather.
The accompanying drawing explanation
Fig. 1 is the structural representation that the LED chip on pcb board is arranged.
Fig. 2 is LED modular structure schematic diagram.
Fig. 3 is the antifog lamp post structure schematic diagram of LED.
The specific embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Refer to Fig. 2, Fig. 3, the antifog street lamp of a kind of LED, comprise a plurality of LED modules 1, driving power 2 and lamp bracket 3, described LED module comprises radiator 11, sealing ring 12, LED chip 13, pcb board 14 and diffuser 15, described LED chip 13 is welded on described pcb board 14, described pcb board 14 is fixed on described radiator 11, radiator is aluminium alloy base plate, good hardness and intensity are arranged, there is fabulous heat conductivity simultaneously, the heat that can be good at LED chip is produced leaves, described sealing ring 12 is arranged between described pcb board 14 and diffuser 15, sealing ring can stop LED chip to be subject to moisture, dust, the erosion of bacterium, improve the service life of street lamp, described a plurality of LED module 1 and driving power 2 are electrically connected to, be arranged on described lamp bracket 3, a plurality of LED modules share lamp bracket, lighting effect is good, simple in structure, reduced the waste of resource, saved the light fixture cost.
In the utility model, described LED chip 13 comprises red LED chip and common White-light LED chip, and described red LED chip and common White-light LED chip are combined by a certain percentage.The LED module spectrum analysis of this kind of combination shows, the percentage occupancy volume in the general zone of gold-tinted is higher, narrow unlike sodium vapor lamp light, colour temperature is low, and higher penetrability is arranged, and the luminous efficiency of current high-end red LED chip also almost reaches the level of white chip simultaneously, red LED chip negligible amounts in the LED module, do not affect the light efficiency of whole street lamp, thereby make street lamp there is stronger light penetration and colour rendering under misty rain weather, guaranteed that vehicle can safe driving at misty rain weather.
In the utility model, described red LED chip two one rows be distributed on described pcb board 14 indirectly.LED die set light source part is comprised of 8-20 LEDs chip, as shown in Figure 1, LED chip is 14, wherein LED-3 ~ LED-12 is white chip, LED-1 ~ LED-2 and LED-13 ~ LED-14 are red light chips, and LED chip is welded to PCB above in the mode of serial or parallel connection, and the chip of LED chip colour temperature of the same race in the paster process is emitted on together, when with machine, carrying out paster, can improve paster efficiency.
