Abstract
The utility model discloses a light-emitting diode (LED) fence tube with overheating protection function. The LED fence tube comprises an LED light source, a printed circuit board (PCB), an electronic control circuit and a fence tube shell. The LED fence tube is characterized in that: a thermal protection component is connected between the PCB and the electronic control circuit. The thermal protection component is connected with the electronic control circuit, the PCB and a power supply through leads so that the thermal protection component is connected in series with the PCB and the electronic control circuit. The fence tube shell is made of a full glass fiber double-side panel, and a base of the fence tube is made of aluminum material. Before encapsulation, the PCB and the aluminum base are pressed together during injection molding. The heat dissipation effect of the LED fence tube can be enhanced, and the service life of the LED fence tube can be prolonged.
Description
Technical field
The utility model relates to the application lighting field, and refering in particular to is a kind of overheat protective function LED guardrail pipe that has.
Background technology
Places such as LED guardrail pipe is widely used in bridge, square, building profile, strides the street air corridor, contour of building, road lamp decoration, various illuminated signs board, show window, stage, mansion, hotel, market are decorated, and are the leading products of city lighting engineering.Night, effect was especially eye-catching, and to the beautifying city, mould the meaning that view has particular importance.But the development of the LED industry that the heat radiation of the heat dissipation problem, particularly great power LED of LED at present directly restricts.Simultaneously the heat dissipation problem of LED also burns device easily, shortens the service life of LED, even causes secondary disaster such as fire.So, under the overall background that the LED heat dissipation problem is not solved at all at present, take some peripheral safeguard procedures to limit the problem that the LED heat radiation is caused, be a kind of more rational way.
The utility model content
The technical problems to be solved in the utility model is a LED guardrail pipe caloric value height, thereby causes the LED luminous efficiency low, causes that easily device burns, even problem such as initiation fire.
For solving the problems of the technologies described above, the utility model comprises led light source, the PCB circuit board, and electronic control circuit, the guardrail pipe shell is characterized in that being connected with between PCB circuit board and the electronic control circuit heat protection components and parts.Heat protection components and parts are connected with power supply with the PCB circuit board with electronic control circuit by lead, thereby make heat protection components and parts and PCB circuit board, and electronic control circuit is formed series connection.Heat protection components and parts do not have ill-effect to the PCB circuit board, can not influence LED luminous efficiency and illumination effect on the PCB circuit board.Heat protection original paper can perception around guardrail pipe internal temperature, when temperature in the guardrail pipe reached the temperature protection value of setting, heat protection components and parts will automatic disconnection, formed before series circuit will open circuit.LED lamp outage on the PCB circuit board, then the temperature in the guardrail pipe can descend, and can effectively protect the service life of its guardrail pipe.
As improvement of the technical scheme, described a kind of overheat protective function LED guardrail pipe that has is characterized in that the PCB circuit board adopts full glass dual platen material to be connected with led light source.
Full glass dual platen is in welding quality and protection against the tide, and ageing resistance and electrical aspect all are better than other encapsulating materials such as cardboard single sided board or half glass single sided board.
As further improvement in the technical proposal, described a kind of overheat protective function LED guardrail pipe that has, guardrail pipe base adopt aluminium, it is characterized in that before the encapsulation when injection moulding PCB circuit version suppressed with the aluminium base forming.
The beneficial effects of the utility model are: heat protection components and parts can effectively be protected LED guardrail pipe, prevent the too high other problems that causes of temperature.The guardrail pipe shell adopts full glass dual platen simultaneously, can improve the service life of PCB circuit board greatly.Guardrail pipe base adopts aluminium, the PCB circuit board is suppressed forming simultaneously before the encapsulation when injection moulding with the aluminium base, can strengthen the radiating efficiency of guardrail pipe.
Description of drawings
Fig. 1 is a kind of overheat protective function LED guardrail pipe schematic diagram that has
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is according to for a kind of New LED guardrail pipe, has structure and comprises led light source 1, PCB circuit board 2, electronic control circuit 3, heat protection components and parts 4, guardrail pipe shell 5, guardrail pipe base 6.Guardrail pipe shell 5 adopts transparent engineering plastics to make.With lead PCB circuit board 2 and heat protection components and parts 4 and electronic control circuit 3 are formed series circuit.4 pairs of PCB circuit 2 plates of heat protection components and parts do not have bad workpiece can perception around guardrail pipe internal temperature, when temperature in the guardrail pipe reached the temperature protection value of setting, 4 of first devices of heat protection will automatic disconnection, formed before series circuit will open circuit.LED illuminator 1 outage on the PCB circuit board 2, then the temperature in the guardrail pipe can descend, and can effectively protect the service life of guardrail pipe.Guardrail pipe base 6 adopts aluminium.Because the heat conductivility of aluminium is fine, can be effectively the heat of guardrail pipe be conducted out by base.When injection moulding, PCB circuit board 2 and aluminium base 6 usefulness heat conductive silica gels are compressed to one before the encapsulation.Being provided with the screens that the guardrail base is installed in guardrail pipe shell 5 inwall both sides, is that guardrail pipe base 6 can combine with guardrail pipe shell 5 easily.
