Description

Technical Field

[0001] The utility model relates to the field of lamps, in particular to a lighting lamp with power regulation and temperature control functions. Background Art

[0002] At present, in the safety regulations of lamps, workers need to select lamps of different powers for assembly according to the installation environment of the lamps. For example, when the installation occasion requires high brightness requirements and non-flammable occasions, workers can choose to assemble high-power lamps, and high-power lamps need to meet the high brightness requirements, but they are also prone to temperature rise. When the installation occasion contains flammable materials, only low-power lamps can be selected for assembly. Low-power lamps have lower brightness, but are not prone to temperature rise. However, when workers purchase lamps, they may not know whether the installation location is a non-flammable occasion, which causes troubles in purchase and installation. In addition, workers may misoperate and assemble high-power lamps in flammable occasions, causing obvious temperature rise in the lamps, which is easy to cause safety accidents and affect the service life of the lamps. The applicant provides a new lighting lamp with power adjustment through the improvement and perfection of existing lighting lamps for consumers to choose and use. Summary of the invention

[0016] Figure 2 This is a structural schematic diagram of Example 2 of the present utility model.

[0017] Figure 3 This is a structural schematic diagram of Example 3 of the present utility model. DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example

[0019] like Figure 1 As shown, a lighting lamp with power regulation and temperature control functions includes a light source 2 connected in series to a conductive circuit 1, a power regulator 4 connected in series to the conductive circuit 1, and a temperature control device electrically connected to the power regulator 4 or connected in series to the conductive circuit 1, wherein the temperature control device is adjacent to or abuts against the COB light source 2, and the working power of the COB light source 2 is adjusted by the temperature control device, or / and the conductive circuit 1 is turned on or off by the temperature control device.

[0020] This lighting lamp can work in low power or high power state through the control of power regulator 4, and can be selected through the power regulation circuit, so that the lighting lamp can be suitable for high brightness requirements and non-flammable occasions, and can also be suitable for flammable occasions.

[0021] In addition, the power regulator 4 is equipped with a temperature control device, which can control the power regulator 4 to automatically switch to low power when the COB light source has a temperature rise at high power, or automatically cut off the conductive circuit when the COB light source has a temperature rise at high power, and stop the COB light source from continuing to use, thereby preventing the lighting lamp from having an abnormal temperature rise, and avoiding safety accidents caused by the lighting lamp being used in a low-power situation but switched to a high-power situation, so that the lighting lamp meets safety regulations and improves the safety of the lighting lamp.

[0022] The power regulator 4 includes a selection switch 41 and a high-power circuit 42 and a low-power circuit 43 connected in parallel to the conductive circuit 1. The conductive circuit 1 selects the high-power circuit 42 or the low-power circuit 43 to be connected in series with the COB light source 2 through the selection switch 41; the power regulator 4 can quickly switch between the high-power circuit 42 and the low-power circuit 43.

[0023] In this embodiment, the temperature control device includes a temperature sensing element 5, which is electrically connected to the power regulator 4 to form a signal loop. The temperature sensing element 5 is adjacent to or abuts against the COB light source 2. The temperature sensing element 5 senses the temperature and feeds back to the power regulator 4, so that the power regulator 4 controls the selection switch 41 to switch from the high-power circuit 42 to the low-power circuit 43.

[0024] When the COB light source 2 is used at high power in a flammable environment, temperature rise is likely to occur. The temperature sensing element 5 immediately senses the temperature. When the temperature exceeds the normal value, the power regulator 4 is controlled to drive the selection switch 41 to switch to low power use.

[0025] The power regulator 4 is provided with a manual operating member 44 linked with the selection switch 41. The manual operating member 44 is provided with a high power position and a low power position. The manual operating member 44 switches between the high power position and the low power position to control the selection switch 41 to be connected in series with the high power circuit 42 or the low power circuit 43. Through the manual operating member 44, the worker can judge the installation occasion before assembly, and then operate the manual operating member 44 immediately to drive the selection switch 41 to switch the high power circuit 42 or the low power circuit 43.

[0026] The conductive circuit 1 is electrically connected to the driving power supply, a common positive terminal 204 is provided on the COB light source 2, and the power regulator 4 is connected in series to the conductive line between the driving power supply and the common positive terminal 204. Example

[0027] The difference between the second embodiment and the first embodiment is that: Figure 2 As shown, the temperature control device includes a sudden jump thermostat 6, the sudden jump thermostat 6 is connected in series to the conductive circuit 1, and the temperature sensing end of the sudden jump thermostat 6 is abutted against the COB light source 2. When the sudden jump thermostat 6 senses that the temperature of the COB light source 2 is equal to or exceeds the preset temperature value, the sudden jump thermostat 6 disconnects the conductive circuit 1;

[0028] The sudden trip thermostat 6 directly disconnects the conductive circuit 1. On the one hand, it prevents the COB light source 2 from using high power in flammable situations. On the other hand, when the COB light source 2 uses high power in non-flammable situations and an abnormal temperature rise occurs, the conductive circuit 1 can be directly disconnected to stop the COB light source 2 from continuing to work, thereby improving the safety of the lighting lamp. Example

[0029] In the third embodiment, Figure 3 As shown, the temperature control device can be a combination of the temperature sensing element 5 of the first embodiment and the sudden jump thermostat 6 of the second embodiment, so that the lighting lamp has the functions of adjusting power by temperature sensing and directly disconnecting the conductive circuit 1.

[0030] The above-mentioned lighting lamps are mainly ceiling downlights. A radiator is provided on the back of the COB light source, and the temperature control device is arranged on the radiator. Since some ceilings are provided with sound insulation cotton, which also has a certain heat preservation effect, when the COB light source is driven at high power, its temperature rises rapidly. If it cannot be effectively and quickly ventilated and dissipated, the sound insulation cotton is easily ignited, posing a safety hazard. By setting the power adjustment, in theory, after the power is lowered, there will be no phenomenon of higher and faster temperature rise. However, it is not ruled out that the adjustment to low power drive is forgotten during installation. By setting the temperature control device, the power can be cut off in time when high temperature occurs to avoid accidents, and it is also convenient for the installation master to switch it to low power in time.

[0031] The above is a preferred embodiment of the utility model, which shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model, and these changes and improvements fall within the scope of the utility model to be protected, and the scope of protection of the utility model is defined by the attached claims and their equivalents.
