Description
Technical Field
[0001] The utility model belongs to the technical field of LED lighting, and particularly refers to a plastic-encased aluminum light source. Background Art
[0002] At present, LEDs have been applied in the market for a long time, and their main fields are palm computers, mobile phones, and other consumer electronics markets. However, the lifespan of such products is relatively short and the iteration is relatively fast. With the continuous progress of LED design and process technology, it has promoted the continuous improvement of LED brightness in order to compete with incandescent lamps, fluorescent lamps, and even halogen lamps. And like most electronic devices, heat is also the biggest threat to LEDs. The existing effective way to improve the heat dissipation of LEDs is the heat dissipation method of interference fit between the aluminum substrate and the aluminum cup. The heat of the lamp beads is transferred to the outer shell aluminum cup through the aluminum substrate, and then the aluminum cup is transferred to the heat-conducting plastic for heat dissipation.
[0003] The existing lamp source structure of the plastic-encased aluminum light source is relatively fixed. For example, for LED downlights or spotlights, usually the aluminum substrate equipped with lamp beads is integrally installed and sealed in the lamp barrel seat. The gap between the PCB board and the LED lamp beads is small or in an integrated form, and it is easy to damage the components on the PCB board due to the heat generated by the lamp beads. At the same time, due to its relatively single structure, it is difficult to perfect the functions, so the applicable range is small. Summary of the Invention
[0004] The purpose of the utility model is to provide a plastic-encased aluminum light source, which has good internal heat dissipation effect, convenient installation, and diverse functions with a wide applicable range.
[0005] The purpose of the utility model is achieved as follows:
[0006] A plastic-encased aluminum light source includes a lamp shell with an opening at one end. At the end of the lamp shell far from the opening, an installation groove with a gradually decreasing diameter is formed. The installation groove is internally connected with a PCB board. A clamping ring is arranged on the inner wall of the installation groove, and an aluminum substrate is abutted on the clamping ring. LED lamp beads are installed on the aluminum substrate. An installation gap is formed between the PCB board and the aluminum substrate. A light-transmitting cover for sealing is covered on the opening, and the aluminum substrate is located between the PCB board and the light-transmitting cover.
[0007] The utility model is further arranged such that a plurality of components are arranged at the bottom of the PCB board. If the components include a rheostat, a sliding rod is arranged at the bottom of the rheostat. A sliding opening is formed at the bottom of the lamp shell, and a T-shaped sliding rod is inserted into the sliding opening. The top of the T-shaped sliding rod is sleeved on the bottom of the sliding rod.
[0008] The present utility model is further configured such that the T-shaped slide bar includes a sliding portion and a slide bar fixedly connected to the top of the sliding portion. A fine sliding hole for the sliding of the slide bar is provided in the sliding opening, and the upper end surface of the sliding portion abuts against the edge of the sliding opening.
[0009] The present utility model is further configured such that a catch is provided on the side wall of the slide bar. When the T-shaped slide bar is inserted into the sliding opening, the end of the catch abuts against the upper edge of the fine sliding hole.
[0010] The present utility model is further configured such that a metal layer made of aluminum is provided inside the lamp housing, and the metal layer fits the inner surface of the lamp housing.
[0011] The present utility model is further configured such that the material of the lamp housing is heat-conducting plastic.
[0012] The prominent and beneficial technical effects of the present utility model compared with the prior art are as follows:
[0013] 1. For the plastic-coated aluminum light source provided by the present utility model, the aluminum substrate for assembling lamp beads is clamped and installed by means of a clamping ring, so that there is a certain installation gap between it and the PCB board, ensuring that the heat-generating aluminum substrate reduces the high-temperature influence on the PCB board, improving the heat dissipation effect, and at the same time, the installation is more convenient in the form of clamping.
[0014] 2. The variable resistor for adjusting the lighting effect further provided by the present utility model, through the T-shaped slide bar provided at the sliding opening at the bottom of the lamp housing, facilitates the artificial adjustment of the color temperature, optimizes the function, and makes it have a wider application range.
[0015] 3. The present utility model further provides a fine sliding hole in the sliding opening, enabling the sliding position to be covered by the sliding portion during the sliding process of the T-shaped slide bar, ensuring the dust-proof and waterproof effects of the sliding position.
[0016] 4. The present utility model further provides a catch on the slide bar of the T-shaped slide bar, making the T-shaped slide bar not easily fall off and enabling the sliding portion to fit more closely, further enhancing the dust-proof and waterproof effects.
[0017] 5. The aluminum metal layer provided by the present utility model can facilitate the installation of the aluminum substrate and at the same time achieve the effect of heat equalization. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present utility model will be further described below with specific embodiments in conjunction with the accompanying drawings. See Figure 1 — Figure 5 :
[0031] A plastic-coated aluminum light source includes a lamp housing 1 having an opening 10 at one end. At the end of the lamp housing 1 far from the opening 10, a mounting groove 11 with a gradually decreasing diameter is formed. The mounting groove 11 is internally fitted with a PCB board 2. A clamping ring 12 is provided on the inner wall of the mounting groove 11. An aluminum substrate 3 abuts against the clamping ring 12. LED lamp beads 30 are installed on the aluminum substrate 3. A mounting gap 31 is formed between the PCB board 2 and the aluminum substrate 3. The opening 10 is covered with a light-transmitting cover 4 for sealing. The aluminum substrate 3 is located between the PCB board 2 and the light-transmitting cover 4.
[0032] In the actual installation process, since the mounting groove 11 is designed to gradually decrease, the PCB board will be gradually clamped when installed into the mounting groove 11. After installing the PCB board, the aluminum substrate 3 is installed. And the LED lamp beads are installed on the aluminum substrate, and the aluminum substrate is positioned and installed by means of the clamping ring. There will be a certain mounting gap 31 between the aluminum substrate and the PCB board, so that the heat-generating aluminum substrate will not conduct too much heat to the PCB board. The installation of the aluminum substrate can also play a good positioning role through the clamping ring, ensuring the stable light emission of the LED lamp beads. At the same time, the whole is not sealed with glue between the lamp housing, which also ensures a good heat dissipation effect.
[0033] Preferably, a number of components are provided at the bottom of the PCB board 2. If the components include a rheostat 20, a sliding rod 21 is provided at the bottom of the rheostat 20. A sliding opening 13 is formed at the bottom of the lamp housing 1, and a T-shaped sliding rod 5 is inserted into the sliding opening 13. The top of the T-shaped sliding rod 5 is sleeved on the bottom of the sliding rod 21.
[0034] In the above structure, a rheostat for adjusting the brightness of the LED lamp beads is provided on the PCB board. The adjustment of the rheostat is slidably adjusted by the T-shaped sliding rod 5 at the sliding opening 13, so that the light source can have the effect of adjusting the color temperature. The adjustment function can be realized by sliding, which is convenient to operate and is suitable for more usage environments.
[0035] Preferably, the T-shaped sliding rod 5 includes a sliding part 50 and a sliding rod 51 fixedly connected to the top of the sliding part 50. A thin sliding hole 14 for the sliding of the sliding rod 51 is provided in the sliding opening 13, and the upper end surface of the sliding part 50 abuts against the edge of the sliding opening 13.
[0036] Adopting the above structural method, the sliding opening 13 is used for the insertion and installation of the T-shaped sliding rod 5, and the thin sliding hole 14 is for the sliding of the sliding rod 51 in the T-shaped sliding rod 5. During the sliding process, the sliding part 50 can fit against the outer edge of the thin sliding hole, so that it can play a dust-proof and waterproof effect on the sliding opening 13 during sliding, and avoid damaging the PCB board.
[0037] Preferably, a hook 52 is provided on the side wall of the sliding rod 51. When the T-shaped sliding rod 5 is inserted into the sliding opening, the end of the hook 52 abuts against the upper edge of the thin sliding hole 14.
[0038] The above hook can effectively prevent the T-shaped sliding rod 5 from falling off after it is inserted.
[0039] Preferably, an aluminum metal layer 6 is provided inside the lamp housing 1, and the metal layer 6 fits against the inner surface of the lamp housing 1.
[0040] Preferably, the material of the lamp housing 1 is heat-conducting plastic.
[0041] In the above structure, the lamp housing 1 made of heat-conducting plastic has a good insulation effect. The use of the metal layer 6 can evenly heat the heat generated on the aluminum substrate inside, and has better heat dissipation. In addition, the metal layer 6 is usually made of aluminum.
[0042] In addition, a reserved opening is formed at the bottom of the lamp housing for the penetration and connection of the power supply wire.
