Abstract
The invention provides a light-emitting diode (LED) street lamp with a protective pendant chain and a tooling hole. The LED street lamp with the protective pendant chain and the tooling hole mainly solves the problems that an LED street lamp power supply with the protective pendant chain and the tooling hole in the prior art is large in inductor heat generating amount, large in size, poor in heat dissipation of a power tube, large in stress of a pin, poor in heat dissipation performance of the power supply and incapable of working under a high-temperature high-dampness environment. The LED street lamp with the protective pendant chain and the tooling hole comprises an LED light source, an LED power supply, a street lamp shell body and a street lamp cover. Due to the fact that thin wires with a diameter smaller than 0.1mm are adopted, the LED street lamp with the protective pendant chain and the tooling hole can increase active area, reduce size of the conductor, solve the problem of heat dissipation and the problem of the stress of the pin; due to vertical arrangement, an air duct is formed and beneficial to heat dissipation caused by circulation of air current, and heat dissipating effect is further improved.

Background technology
High-power with the LED street lamp in pendant chains and frock hole different from conventional high-pressure mercury lamp street lamp be, the efficient white light-emitting diodes that the light source of high-power LED street lamp with pendant chains and frock hole adopts low-voltage DC supply, synthesized by GaN based power type blue-ray LED and yellow fluorescent powder, have the particular advantages such as efficient, safety, energy-saving and environmental protection, life-span length, fast response time, colour rendering index height, can be widely used in city illumination.High-power LED street lamp with pendant chains and frock hole effectively reduces windage and weight, alleviates the load of lamp stand, strengthens safety coefficient.
The inductance of existing LED street lamp with pendant chains and frock hole generally takes thick line to be wound around (wire diameter is generally greater than 1mm), can cause like this Kelvin effect of inductance to increase, and the inductance heating is large; In order to address this problem, the technical staff adopts the mode of dwindling wire diameter, but after dwindling wire diameter, fine rule is more difficult fixing after winding, even can line pressure is disconnected.
The power tube of existing LED street lamp with pendant chains and frock hole generally is set directly on wiring board, causes like this heat comparatively concentrated, is unfavorable for heat radiation; In order to address this problem, the technical staff adopts the set-up mode perpendicular to wiring board, but has increased like this stress of pin, and long-term use easily causes potential safety hazard.
The vacant unit of existing LED street lamp with pendant chains and frock hole is generally positioned on wiring board, and this set-up mode is unfavorable for heat radiation, is not suitable for the normal operation of hot and humid environment.
Summary of the invention
The invention provides a kind of LED street lamp with pendant chains and frock hole, the inductance caloric value that has mainly solved existing LED road lamp power supply with pendant chains and frock hole is large, volume is large, the power tube heat dispersion is poor, pin stress is large, the power supply heat sinking poor performance, the problem of working in hot and humid environment again.
Concrete technical solution of the present invention is as follows:
This is with the LED street lamp in pendant chains and frock hole, comprise LED light source, LED power supply, street lamp casing and street lampshade, described street lampshade is connected with the street lamp casing light source side outside being arranged at LED light source, be provided with heat abstractor on the street lamp casing dorsal part, the centre of heat abstractor is provided with groove, and shape and the street lamp post of groove cross section are suitable; Described street lamp casing dorsal part also is provided with pressing plate, and the cavity that forms between pressing plate and groove is used for inserting street lamp post, and pressing plate is fixedly connected with street lamp casing by locking device; Be provided with at least one lightening hole on described pressing plate, do flange around lightening hole and process; The street lamp dorsal part also is provided with at least two root guard chain slings; Be provided with at least two frock holes in described groove, the height in frock hole is less than groove height; Jockey is connected respectively LED light source by the frock hole and is connected with pressing plate; The jockey that is connected with LED light source, it is provided with waterproof sealing layer away from LED light source one side end; Jockey after installation is lower than the frock hole; Described LED power supply comprises wiring board, power supply box body and power supply lid, described wiring board is fixedly installed in the power supply box body, the power supply box body is " U " type or " L " type, comprises power pack body sidewall and power supply box plate, and wiring board is fixedly installed on the power supply box plate; Be provided with inductance on described power pack body sidewall, inductance is electrically connected to wiring board; Described inductance is by the fine rule coiling of diameter less than 0.01mm; Described inductance is fixed on the power pack body sidewall by screw, be provided with the insulating radiation elastomeric pad between described inductance one side and power pack body sidewall, the inductance opposite side is disposed with the insulating radiation elastomeric pad, fixedly compressing tablet and hold-down nut, fixedly compressing tablet is provided with the flange that is used to the screw guiding near the insulating radiation elastomeric pad; Described power tube is electrically connected to wiring board, and power tube is fixedly installed on the power pack body sidewall; Vacant unit independently is vertically installed on wiring board, and the operating temperature of vacant unit is-40 ℃～100 ℃.
The invention has the advantages that:
This LED street lamp with pendant chains and frock hole has adopted the fine rule of diameter less than 0.1mm, adopted simultaneously the insulating heat-conductive cushion to be carried in coil two ends, use again the fixedly compressing tablet that turns over time with ring-type that it is fixed, increased effective area, dwindled the volume of inductance, volume can be down to original 1/5; Power tube is arranged on the power pack body sidewall, and then pin is connected with wiring board, because the power pack body sidewall is that heat sink material is made, and power tube is completely fixed and be fitted on the power pack body sidewall, namely solve heat dissipation problem, solved again the stress problem of pin; With vacant unit setting mounting means in the circuit board, easy heat radiation is set like this, can carry out independent replacing to vacant unit, be applicable to hot and humid environment, can at-40 ℃～100 ℃, work in 90% humidity environment; When in power supply, humidity was larger, dew can flow down along the wiring board of erectting; Simultaneously, erect setting and can form the air channel, be beneficial to airflow and take away heat, further improved radiating effect.
