Abstract

The utility model relates to a heat dissipation system for LED fluorescent lamps, which comprises LED fluorescent lamps, a temperature sensor, a heat dissipation miniature fan and a control unit. The temperature sensor collects the temperature on the circuit board and sends it to the control unit for processing. The temperature value controls the heat dissipation of the micro fan to turn on or control the number of working in multiple LEDs. Because the utility model controls the heat dissipation miniature fan in the heat dissipation annular groove through the control system, when the temperature value collected by the temperature sensor is too high, the heat dissipation microfan will be started to dissipate heat, thereby effectively controlling the heat dissipation of the LED fluorescent lamp.

technical field

The utility model relates to a cooling system for lamps, in particular to a cooling system for LED fluorescent lamps.

Background technique

LED is a solid-state semiconductor device that converts electricity directly into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and hole occupies an leading position in it, and the other end is N-type semiconductor, and here mainly is electron. But time these two kinds of semiconductors couple together, between them, just form a P-N junction. When electric current acts on this chip by wire time, electron will be pushed to P district, and in P district, electron is with hole recombination, then will send energy with the form of photon, the principle of LED luminescence that Here it is.

Due to the large heat dissipation of LED lamps, if they cannot be dissipated in time, especially high-power LEDs or LED fluorescent lamps will burn out electronic components after a long time of use, affecting the normal use and life of LED lamps.

As shown in Figure 1, LED fluorescent lamp heat dissipation system 1 includes arc reflector 2 and light emitting diodes 3, light emitting diodes 3 are easy to concentrate on the circuit board below it, not easy to dissipate heat, and will burn out the circuit board after a long time.

Contents of the invention

The utility model designs a heat dissipation system for LED fluorescent lamps, which solves the technical problem that the heat dissipation effect of the existing heat dissipation system for LED fluorescent lamps is not good.

In order to solve the above-mentioned technical problems, the utility model adopts the following scheme:

A heat dissipation system for LED fluorescent lamps, including LED fluorescent lamps, temperature sensors, heat dissipation miniature fans and a control unit, the temperature sensor collects the temperature on the circuit board and sends it to the control unit for processing, and the control unit controls the temperature according to the temperature value collected by the temperature sensor The heat dissipation micro fan turns on or controls the number of working in multiple LEDs.

Further, the LED fluorescent lamp includes an arc-shaped reflector, and a plurality of light-emitting diodes are installed on the arc-shaped reflector through a circuit board, and a heat-dissipating annular groove is connected to the back of the arc-shaped reflector, and the arc-shaped reflector is connected to the arc-shaped reflector. The material of both the heat dissipation annular grooves is the same metal, and the arc reflector is connected tangentially to the heat dissipation annular groove.

Further, the heat dissipation micro fan is arranged in the heat dissipation annular groove.

Further, the material of both the curved reflector and the heat dissipation annular groove is aluminum.

Further, the arc-shaped reflector is integrally formed with the heat dissipation annular groove.

Compared with the traditional LED fluorescent lamp cooling system, the LED fluorescent lamp cooling system has the following beneficial effects:

(1) Because the utility model controls the heat dissipation miniature fan in the heat dissipation annular groove through the control system, when the temperature value collected by the temperature sensor is too high, the heat dissipation microfan will be started to dissipate heat, so that the LED fluorescent lamp can be effectively cooled. thermal control.

(2) The utility model can also control the number of working LEDs, so if the heat is too concentrated when using high-power LEDs, it can control part of the LEDs to work and partly stop working, so as to ensure normal temperature operation environment.

(3) Since the utility model is connected with a heat dissipation annular groove on the back of the arc reflector, the metal heat dissipation annular groove and the arc reflector can jointly export a large amount of heat emitted by the light-emitting diodes and conduct heat dissipation, ensuring the heat dissipation of the LED fluorescent lamp. safe use. the

Detailed ways

Below in conjunction with Fig. 2 to Fig. 4, the utility model is further described:

As shown in Figure 2, a heat dissipation system for LED fluorescent lamps includes a curved reflector 2, a plurality of light emitting diodes 1 are installed on the curved reflector 2 through a circuit board, and a heat dissipation annular groove 4 is connected to the back of the curved reflector 2 , the arc reflector 2 and the heat dissipation annular groove 4 are both made of the same metal, and the arc reflector 2 and the heat dissipation annular groove 4 are connected tangentially. The heat dissipation annular groove made of metal and the curved reflector can jointly dissipate and dissipate a large amount of heat emitted by the light-emitting diodes and dissipate heat, ensuring the safe use of the LED fluorescent lamp heat dissipation system.

The arc reflector 2 and the heat dissipation annular groove 4 are integrally formed, and the material of both the arc reflector 2 and the heat dissipation annular groove 4 is aluminum.

As shown in FIG. 3 , a heat dissipation miniature fan 5 is installed in the heat dissipation annular groove 4 . The heat dissipation miniature fan 5 can blow away the large amount of heat accumulated on the heat dissipation annular groove, so that the large amount of heat emitted by the light emitting diode can be exported in time to ensure the safe use of the LED fluorescent lamp heat dissipation system.

As shown in Figure 4, a LED fluorescent lamp heat dissipation system includes LED fluorescent lamp 1, temperature sensor, heat dissipation micro fan 5 and a control unit. The temperature sensor collects the temperature on the circuit board and sends it to the control unit for processing. The numerical value of the temperature controls the heat dissipation micro-fan 5 to turn on or controls the working quantity of the plurality of light emitting diodes 3 .

Because the utility model controls the heat dissipation miniature fan in the heat dissipation annular groove through the control system, when the temperature value collected by the temperature sensor is too high, the heat dissipation microfan will be started to dissipate heat, thereby effectively controlling the heat dissipation of the LED fluorescent lamp.

In addition, since the control unit can control the working number of multiple light emitting diodes, if the heat is too concentrated when using high-power LEDs, it can control some light emitting diodes to work and some to stop working, so as to ensure a normal temperature working environment.

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the realization of the utility model is not limited by the above-mentioned method, as long as various improvements of the method concept and technical solutions of the utility model are adopted, or the utility model is not improved. Directly applying the conception and technical solutions of the utility model to other occasions is within the protection scope of the utility model.
